Teknologi akuakultur bioflok merupakan metode menjaga kualitas air dalam budidaya ikan. Penjagaan kualitas air dilakukan dengan mengubah nitrogen anorganik menjadi nitrogen organik yang tidak bersifat toksik menggunakan bakteri. Bakteri ini dapat mengkonversi limbah organik menjadi kumpulan mikroorganisme berbentuk flok yang dimanfaatkan oleh ikan sebagai sumber makanan. Namun metode bioflok memerlukan pemantauan air secara teratur untuk menjaga kualitas air. Oleh karena itu pada penelitian ini dirancang bangun sebuah sistem yang dapat menjaga kualitas air pada kolam ikan bioflok berdasarkan suhu air, TDS air, dan pH air menggunakan komunikasi Long Range agar dapat memantau dan mengontrol kolam dari jarak jauh. Alat yang digunakan untuk komunikasi Long Range adalah LoRa RFM95W. Hasil pengujian pengiriman data menggunakan LoRa dalam keadaan LOS dapat diterima hingga jarak 300 meter dengan nilai RSSI adalah -100dBm. Semua sensor dapat bekerja dengan baik seperti sensor suhu air, TDS air, dan pH air yang dapat membaca perubahan nilai yang terjadi pada air kolam bioflok tiap waktu. Selain itu, pemberian pakan ikan secara otomatis dapat dilakukan sesuai jadwal yang ditentukan dengan bantuan modul RTC. Respon yang diberikan saat kondisi air tidak dalam batas normal juga dapat berjalan baik dengan menyalakan buzzer dan menampilkan notifikasi pada aplikasi.

Short mackerel is one of small pelagic species which is prioritized in fisheries management of East Java. The first steps to improve this fishery is to carry out stock assessment, the impact of fisheries on the environment, and effective management. This study aims to identify and categorize the species supporting the mackerel fishery in Fisheries Management Area (FMA) 712, especially those caught by purse seine vessels in IPPP Paiton, Probolinggo. This study found that there were two species of short mackerel, Rastrelliger branchysoma and R. kanagurta. There were 16 species interacting with this fishery, none of them were included in the Endangered, Threatened, and Protected (ETP) category based on the IUCN Redlist. These species are categorized into 2 groups, namely main secondary (5 species) and minor secondary (11 species), with the largest proportion being was goldstipe sardine. This information can be a start in the fisheries improvement program of short mackerel fishery in East Java. Future research related to the stocks, habitats and ecosystems of each species can be carried out to complete the information and support the formulation as well as implementation of fisheries improvement program of short mackerel fishery in East Java. Ikan kembung merupakan salah satu jenis pelagis kecil yang menjadi prioritas dalam pengelolaan perikanan di Jawa Timur. Salah satu langkah awal untuk melakukan perbaikan perikanan ini adalah dengan melakukan penilaian terkait stok, dampak perikanan terhadap lingkungan, serta tata kelola atau pengelolaan yang efektif. Penelitian ini bertujuan untuk mengidentifikasi dan mengkategorisasi spesies pendukung perikanan kembung pada Wilayah Pengelolaan Perikanan (WPP) 712, khususnya yang ditangkap oleh kapal-kapal purse seine dari IPPP Paiton, Probolinggo.

Based on observations at Josari 01 Elementary School in Tersono District, children's creativity in drawing is still low, because so far, whenever there is a drawing learning activity, children are reluctant to be invited to do activities related to children's fine motor skills. But prefer to choose to play with gadgets and friends than doing activities that are done individually. Therefore this community service aims to improve the creative ability to draw elementary school children in Tersono District, Batang Regency and its surroundings which we focus on children's drawing creativity. The method used is through workshops and drawing assistance for elementary school students in Tersono District, Batang Regency and its surroundings. This community service activity is divided into three sessions, namely the first session provides knowledge about the history of drawing including understanding, history, and types of drawings. The second session was a drawing competition session carried out by all participants. Furthermore, the last session was an assessment session to determine 1st, 2nd and 3rd place winners. The community service program that had been carried out by the STKIP Muhammadiyah Batang Elementary School Teacher Education Study Program had been carried out well and received positive impressions from all participants who took part.

Anti-Drugs Youth Alliance (APAN) is a non-government organization that is engaged in the scope of prevention of drug abuse in South Kalimantan. Although this organization has existed for more than a year until now it still does not have a system that supports its implementation of activities and information. Besides that, problem, another main problem which was found in this study is about the membership management of South Kalimantan APAN, because the member of APAN is widespread in each district and cities in all over the South Kalimantan Area. Based on that problem, this group project implementation aims to make an information system that can manage the South Kalimantan APAN web-based membership system. In this website making, the South Kalimantan APAN information system uses the prototyping method, so that developers and users can have an interaction between one and another along the system making process. The South Kalimantan APAN membership information system that is made is in a form of a website, so it can be accessed by using a computer, laptop, and smartphone at anytime and anywhere if it is connected to the internet., {"references":["Sumarwoto, \"Penyalahgunaan Narkoba Menurut Hukum Positip Dan Hukum Islam,\" Proseding Seminar Unsa, 2014","World Health Statistics, monitoring health for the SDGs, Sustainable Development Goals, Geneva: World Health Organization (WHO), 2017","K.

Perikanan layang yang didaratkan di Pelabuhan Perikanan Nusantara (PPN) Prigi merupakan perikanan pelagis yang disusun oleh tiga spesies sumber daya ikan layang yaitu layang anggur ( Decapterus kuroides ), layang benggol ( Decapterus ruselli ) dan layang deles ( Decapterus macrosoma ). Aturan kendali tangkap pada perikanan layang kerap menggunakan model konvensional spesies tunggal, meski secara teknis tidak sesuai digunakan pada perikanan layang tercampur yang disusun oleh lebih dari satu spesies (multispesies). Aplikasi feedback harvest control rule ( HCR ) merupakan alternatif aturan kendali tangkap yang tervalidasi yang dapat digunakan untuk perikanan multispesies. Pada penelitian ini dilakukan estimasi jumlah tangkapan yang diperbolehkan ( allowable biological catch /ABC y ) dengan menggunakan dua aturan kendali tangkap yaitu feedback HCR dan model konvensional surplus produksi Schaefer (1954) dengan menggunakan data hasil tangkapan dan upaya penangkapan (trip) dalam kurun waktu 2011 – 2020. Hasil estimasi model Schaefer (1954) menunjukkan ABC y bahwa hanya dapat diestimasi untuk layang anggur, sementara dua spesies layang lainnya, tidak memenuhi asumsi model Schaefer (1954). Penggunaan aplikasi feedback HCR pada ketiga spesies layang lebih praktis karena mampu mengestimasi ABC y tanpa perlu dilakukan pemisahan data hasil tangkapan dan upaya penangkapan berdasarkan spesies.

Pelagic fish resources have a very important role in regional economic development. The assumption that fish resources are common property so that everyone is free to catch (open access) is a problem with overfishing in East Java waters. The purpose of this study is to determine the superior commodity of small pelagic fish, the status of exploitation of superior fish resources and to compile a scenario of sustainable management of superior resources. The method in this research is quantitative descriptive method with data analysis used including Location Quotient (LQ), Schaefer (1954), Fox (1970), Walter Hilborn, and programming STELLA (System Thinking, Experimental Learning Laboratory with Animation). The research result of the superior species in the province in the south of East Java) is sardin, while the superior fish in the regency is s Rainbow runner. The status of fisheries at the level of superior fisheries exploitation in South East Java, the level of exploitation of ssrdin fish is 240% with the status of Depleted. Finally, the level of exploitation for s Rainbow runner fish is 689%, which means that they are included in depleted. The scenario of sustainable management of pelagic fisheries for the next 10 years, namely 2018 - 2027 for lemuru fish, the highest biomass reserves will be obtained in 2027, using a fixed effort allocation which has biomass reserves of 179% and the potential value of sustainable reserves of 8,438.48 tonnes. The results showed that the superior commodities of small pelagic fish in North East Java were mackerel fish. The superior fish commodity in the Regency / City is obtained by Finny scad fish. The level of exploitation for mackerel is 127% with the status of Over Exploited, and the level of exploitation for Finny scad is 131% with the status of Over Exploited. The scenario for the management of the superior mackerel commodity, the highest biomass reserve in 2027 is the allowable fishing effort allocation (fJTB) of 129%.Key Words: STELLA ,Superior commodity, Fishery status, Sustainable potential

Cassava or better known as cassava is one of the staples of rice which is popular in Indonesia. Cassava plants can flourish in almost all regions of Indonesia. However, cassava is a plant that is susceptible to plant disease, which attacks the disease resulting in a decrease in the amount of productivity of tubers produced by cassava plants. The application of identifying cassava disease based on leaf image is expected to be useful as a support for cassava farming in easily detecting cassava disease, so that it can be dealt with more quickly. This study uses the Gray Level Co-occurrence Matrix (GLCM) method as an extraction feature and the Probabilistic Neural Network (PNN) method for identification processes. Based on the results of tests on 6 types of cassava leaf images, obtained an accuracy of 83.33%.

Banyuurip is one of the villages in Ujung Pangkah District which has potential natural resource that is mangrove forests. However, the occurrence of abrasion and conversion of mangrove land has impacted mangrove ecosystem. Rehabilitation efforts by replanting mangroves have been carried out, but they have not been effective in overcoming the current problems. The reduction of mangrove area that led the decreased of mangrove’s function can affect the livelihood of the local community, including fishermen. The installation of geosynthetic bags, which are sand-filled bags arranged on the ground, is done as an alternative solution in Banyuurip Village which functions as coastal protection and a sediment trap. The utilization of geosynthetic material is often used to help the coastal problem, the used of geosynthetic material is rarely carried out in mangrove areas. This study aims to determine the sediment characteristics, sedimentation rates, and sedimentation process based on the relationship between current velocity and sedimentation rate. The result shows that generally the type of sediment fraction in this location is silt (79,12% - 80,12%) and the rest is clay. The current installation of geosynthetic bags can result in the land extension from the trapped sediment behind the structure. In addition, the current velocity conditions and the sediment transport process also affect the sedimentation process that occurs. The average sedimentation rates around the geosynthetic bags installation area ranged from 150.72-305.01 mg.cm-2.day-1. This study may provide a basic information for further development in Banyuurip Mangrove Center and other mangrove conservation area.

Blue Swimming Crab (Portunus pelagicus, BSC) is one of the Indonesian important fisheries commodities often captured by traps. Under Decree No. 56/2016, the Ministry of Marine Affairs and Fisheries managed the BSC, with the standard size of BSC is >10cm of Carapace Width (CW) or >60 g of Weight (W), and non-berried or carried eggs for female. This study aims to determine BSC's crawling pattern toward the trap, design an escape vent on the trap, and assess catch of BSC using vented trap and non-vented trap. The video footage was used to examine crawling pattern of 30 BSCs on the laboratory. The study also includes field experiment by deploying twenty traps (10 vented traps and 10 non-vented traps) on the sea. The study obtained two crawling patterns of BSC, crawling forward and sideways with the most BSC crawled sideways. Design of escape vent was 4.6 cm length x 2.6 cm height. The BSCs captured in the vented traps have >10cm of CW, while 14% of BSCs in the non-vented traps have

Tempat Pemrosesan Akhir (TPA) Air Dingin, Kota Padang berlokasi dekat dengan perumahan masyarakat sehingga berpotensi menimbulkan masalah bagi aktifitas masyarakat sekitar karena TPA masih menggunakan sistem semi controlled landfill. Oleh karena itu penelitian ini dilakukan untuk menganalisis konsentrasi mikroba di udara berupa jamur dan bakteri, menganalisis korelasi jarak TPA dengan pemukiman warga terhadap konsentrasi mikroba dam menganalisis hubungan aspek klimatologi udara dengan konsentrasi mikroba. Pengambilan sampel mikroba dilakukan pada 6 titik sampling dengan perbedaan jarak dalam 1 titik yaitu 0 meter hingga jarak terjauh yaitu 500 meter berdasarkan arah angin. Konsentrasi jamur tertinggi yang didapat pada 6 titik pengambilan.sampling ialah 5.936 CFU/m3 pada jarak 0 meter dari TPA dan konsentrasi minimum jamur 71 CFU/m3 pada jarak 500 meter dari TPA. Sedangkan untuk bakteri, konsentrasi maksimumnya ialah sebanyak 12.085 CFU/m3 pada jarak 0 meter dan minimumnya 85 CFU/m3 pada jarak 500 meter dari TPA. Jarak pada penelitian ini mempengaruhi konsentrasi mikroba di udara, semakin jauh jarak TPA ke pemukiman maka konsentrasi mikroba semakin menurun dengan nilai r korelasi yaitu 0,41 atau korelasi menengah. Nilai korelasi Aspek klimatologi kelembapan udara dengan nilai 44%-63,6% memiliki nilai r 0,183 yang berarti korelasi lemah, arah grafik korelasi menunjukkan korelasi yang semakin besar kelembapan udara maka konsentrasi jamur dan bakteri semakin tinggi yang menandakan bahwa korelasi yang positif. Aspek klimatologi suhu udara dengan nilai 33,9°C-39,5°C dan kecepatan angin 0,4-0,6 m/s memiliki nilai r 0,25 menunjukkan korelasi yang lemah untuk suhu udara dan nilai r 0,38 menunjukkan korelasi menengah untuk kecepatan angin dengan konsentrasi mikroba. Arah grafik korelasi suhu udara dan kecepatan angin menunjukkan korelasi negatif dimana semakin tinggi kecepatan angin dan suhu udara maka semakin kecil konsentrasi jamur dan bakteri. Dari aspek klimatologi hanya kecepatan angin yang memiliki korelasi yang menengah terhadap konsentrasi mikroba, ini menandakan bahwa kecepatan angin berpengaruh dalam pendispersian atau penyebaran mikroba di udara. Upaya pengendalian agar mikroba di udara dari TPA tidak tersebar ke pemukiman masyarakat adalah dengan penambahan green barrier dengan ketebalan 10 meter di wilayah TPA.

Harlyan LI, Badriyah L, Rahman MA, Sutjipto DO, Sari WK. 2021. Harvest control rules of pelagic fisheries in the Bali Strait, Indonesia. Biodiversitas 23: 947-953. Multispecies pelagic fisheries have contributed as the main fishery production for the Bali Strait fisheries. To maintain the sustainability of the fish stock, sets of harvest control rules (HCRs) have been introduced in terms of fishery management. Conventional single-species surplus production models have been used extensively to determine the future annual allowable biological catch (ABC). However, they may not technically apply to multispecies fishery management. The feedback harvest control rule HCR has been validated and applied to maintain the catch variability of the multispecies fishery. This study aims to technically compare the use of the surplus production model and the feedback HCR in the ABC estimation. The catch and effort data series of the three dominant species from 2010-2019, collected from Pengambengan and Muncar fishing port, were analyzed by two HCRs, the Schaefer surplus production model and the feedback HCR to obtain the ABC. As a result, the Schaefer model showed a higher estimation of ABC than the feedback HCR because the feedback HCR may reflect the recent historical catch consistent with precautionary principles. The feedback HCR showed an initial step toward sustainably managing multispecies fisheries while dealing with unavailability in species-specific data conditions.

The Covid-19 pandemic has brought big changes to the world of education in Indonesia. Learning that should be done in person or face-to-face turns into online learning. This raises problems for the readiness of schools, teachers, and students in carrying out learning. This study aims to obtain information about the effectiveness of digital media in online learning during the Covid-19 pandemic, whether digital media has been effective and its use is optimal in learning. This research is a qualitative descriptive study using an online survey method. The results obtained were that online learning using digital media at SDN 1 Gambasan Temanggung did not increase student scores because only about 20% of student scores had increased, 50% of students also complained about the lack of facilities and infrastructure that support learning. Teachers also have not been able to use digital media in accordance with the characteristics of learning, this is evidenced by 45% of students answered disagree. Students also do not have higher motivation when using digital media, it is proven that only 5% agree. Based on the research results, it can be concluded that digital media is less effective when the supporting facilities and infrastructure are minimal.

Rajungan ( Portunus pelagicus ) merupakan komoditas ekonomis penting ke-4 yang telah dieskpor ke berbagai negara. Berdasarkan Permen KP No. 56 tahun 2016, rajungan hanya boleh ditangkap dengan ukuran lebar karapas > 10 cm atau berat > 60 g ekor -1 . Penelitian ini bertujuan untuk mengetahui pengaruh bubu dengan escape gap terhadap ukuran hasil tangkapan rajungan berdasarkan experimental fishing . Percobaan lapang dilakukan pada bulan Januari - Februari 2019 di Desa Pangkahwetan, Kabupaten Gresik. Analisis data yang digunakan adalah regresi linier dan uji-t. Hasil analisis data didapatkan dimensi escape gap yang sesuai adalah 4,6 * 2,6 (p * t) cm. Hasil tangkapan dengan lebar karapas ≤ 10 cm pada bubu dengan escape gap lebih sedikit dari pada bubu tanpa escape gap (8% : 29%). Bubu dengan escape gap memiliki rata – rata berat yang lebih besar dari pada bubu tanpa escape gap (115,9 : 87,4). Uji-t menunjukkan t hitung < t tabel (1,981 < 2,037) sehingga penggunaan escape gap pada bubu lipat tidak berpengaruh nyata terhadap berat hasil tangkapan rajungan. Penelitian ini dimungkinan bisa memberikan hasil lebih nyata jika ulangan diperbanyak.

Length-growth analysis of fish cannot be completed without age information. Age study on skipjack has been done through analysis of its first-hard dorsal fin. Sampling was done using 11 fish specimen taken from UPT P2SKP Pondokdadap Sendangbiru, from January to February 2018. Species identification follows the FAO standard procedure (species identification sheet) published 2001. A specimen was deposited at Depository Ichtyologicum Brawijaya with code DIB.FISH 111103. The first hard spine of 11 fish samples were cut with IsoMet low speed cutting machine at 50 mm thickness. The preparates were then analyzed using biological binocular microscope at 40x magnification. The results showed differences in number of growth annuli (annual growth-ring) at different fish length (FL). The number of annuli varied between 4 - 6+ age year at fish length (FL) variation between 38 and 62 cm. These values were closely related to those with other methods such as Modal Progression Analysis (MPA). The number of samples successfully analyzed (5 specimen) were not sufficient for analysis of length-growth parameters (L ∞ , k and t 0 ). Also, this technique did not apply for age less than yearly unit, but quite affordable (Rp.50.000,- per sample) for a fairly variable amount of specimens.

An extreme biomass-burning event occurred in Indonesia from September through October 2015 due to severe drought conditions, partially caused by a major El Nino event, thereby allowing for significant burning of peatland that had been previously drained. This event had the highest sustained aerosol optical depths (AOD) ever monitored by the global Aerosol Robotic Network (AERONET). The newly developed AERONET Version 3 algorithms retain high AOD at the longer wavelengths when associated with high Angstrom Exponents (AEs), which thereby allowed for measurements of AOD at 675 nanometers as high as approximately 7, the upper limit of Sun photometry. Measured AEs at the highest monitored AOD levels were subsequently utilized to estimate instantaneous values of AOD at 550 nanometers in the range of 11 to 13, well beyond the upper measurement limit. Additionally, retrievals of complex refractive indices, size distributions, and single scattering albedos (SSA) were obtained at much higher AOD levels than possible from almucantar scans due to the ability to perform retrievals at smaller solar zenith angles with new hybrid sky radiance scans. For retrievals made at the highest AOD levels the fine mode volume median radii were approximately 0.25 to 0.30 microns, which are very large particles for biomass burning. Very high SSA values (approximately 0.975 from 440 to 1020 nanometers) are consistent with the domination by smoldering combustion of peat burning. Estimates of the percentage peat contribution to total biomass burning aerosol based on retrieved SSA and laboratory measured peat SSA were approximately 80-85 percent, in excellent agreement with independent estimates.

Rajungan ( portunus pelagicus ) merupakan salah satu komoditas penting perikanan Indonesia. Pengetahuan tentang aspek biologi rajungan, termasuk hubungan antar ukuran bagian-bagian tubuhnya (morfometrik) dan sebaran lebar karapas serta beratnya, akan berguna sebagai salah satu informasi dalam pengelolaan rajungan. Penelitian ini bertujuan untuk mengetahui hubungan lebar karapas- berat rajungan, hubungan lebar-panjang-tinggi karapas, serta sebaran lebar dan berat rajungan. Metode yang digunakan adalah survei dengan pengambilan sample secara acak pada 2 (dua) titik pendaratan ikan di perairan utara Lamongan, khusunya kecamatan Paciran pada bulan Juli sampai September 2018. Hasil penelitian menunjukkan sifat pertumbuhan isometrik untuk rajungan betina dan allometrik positif untuk rajungan jantan. Selain itu, didapatkan hubungan linear positif dengan nilai a = 0,06 dan b = 0,45 untuk lebar-panjang karapas serta nilai a = 0,06 dan b = 0,25 untuk lebar-tinggi karapas. Rajungan betina paling banyak ditangkap pada lebar karapas 12-13 cm dan berat 100 g, sedangkan rajungan jantan sering ditangkap dengan lebar karapas 11 cm dan berat 80-90 g. Masih adanya rajungan dibawah ukuran lebar karapas 10 cm yang tertangkap (lebar karapas diatas 10 cm adalah aturan rajungan yang boleh ditangkap sesuai dengan PER MEN KP 56/2016), maka informasi tentang hubungan lebar-panjang-tinggi rajungan dapat dijadikan masukan untuk melakukan modifikasi alat tangkap, misalnya mendesain ukuran celah pelolosan pada bubu, agar rajungan dengan lebar karapas dibawah 10 cm dapat keluar dari alat tangkap.

Determination of regional fisheries based upon the experience of fishing master is one obstacle, because the spread of the fish moving in accordance with the fish habitat, while the fish habitat affected by the condition oceanographic parameters.

This study was conducted at Sendang Biru Coastal Fishing Port Malang Regency from February to May 2021, aiming to find out the utilization rate and bioeconomic conditions of the skipjack tuna fishery. The study used descriptive methods. Statistical data on catches from 2011 to 2020 were used to apply bioeconomic analysis to calculate the maximum sustainable yield (MSY), maximum economic yield (MEY), total allowable catch (TAC), and free access equilibrium (FAE). Results showed that values of catch and effort at MSY level were 1,800 tons and 3,191 trips respectively with a value of TAC as much as 1,440 tons. While values of catch and effort at MEY reached 1,774 tons and 2,814 trips respectively with the highest profit obtained as much as IDR 34.12 billion. In addition, catch and effort at FAE level took place at 751 tons and 5,627 trips respectively. The utilization rate of skipjack tuna (K. pelamis) was 123%. In conclusion, the fish is in over-exploited condition hence the amount of effort must be decreased to maintain resources sustainability.

There are 6 of 7 species of sea turtles in the world found in Indonesia. Meanwhile, the existence of sea turtles is currently experiencing a very drastic decline. This research is one of the conservation efforts to increase the number of sea turtles in several turtle conservation areas in East Java. From the experimental results, the temperature is the most influential factor in the sex determination. The development of egg incubation technology in this study has resulted in hatching results with the number of male sex dominant than female. To produce male eggs the temperature in the hatching media is between 25°C - 30°C, while the optimal temperature for hatching female eggs is >30°C. The artificial turtle egg incubator technology is designed in such a way that the conditions in the hatching chamber are close to the hatching conditions in nature with a temperature that can be set with an incandescent lamp equipped with a temperature sensor, when the high temperature the temperature sensor will work and the incandescent lamp automatically turns off. Optimum moisture conditions of about 70% water content can be regulated by the humidity sensor, when humidity is reduced, it can automatically spray water.

Sejak tahun 2013, Pemerintah Desa Banyuurip bersama dengan Kelompok Pelestari Mangrove dan Lingkungan Banyuurip mendirikan Kawasan Ekowisata dan Konservasi Mangrove yang dikenal dengan nama Banyuurip Mangrove Center (BMC). Selain sebagai tempat pembibitan dan pelestarian mangrove, kawasan ekowisata yang mulai dibuka pada tahun 2015 ini memiliki berbagai jenis mangrove dengan jenis yang mendominasi adalah Avicennia sp. dan Rhizophora. Saat buah mangrove melimpah, penduduk sekitar BMC kadang memanfaatkannya sebagai olahan seperti sirup dan jenang untuk dikonsumsi sendiri. Berangkat dari permasalahan ini, Program Doktor Mengabdi Universitas Brawijaya Tahun 2018 dilakukan untuk membantu para pengelola ekowisata mangrove dalam memanfaatkan dan mengelola produk-produk mangrove untuk mengembangkan ekowisata mangrove yang telah berjalan. Kegiatan yang dilakukan untuk mengatasi masalah tersebut adalah dengan mengadakan pelatihan pengolahan produk mangrove oleh praktisi dari Lamongan yang telah sukses mengolah kopi mangrove serta tim dari KeSEMaT, Semarang yang telah memiliki banyak desa binaan dengan berbagai macam produk seperti stik mangrove, krupuk mangrove, cendol mangrove serta batik mangrove. Dengan adanya pemanfaatan dan pengelolaan produk mangrove, maka BMC diharapkan dapat menjadi satu paket tempat wisata yang lengkap, yakni wisata alam, wisata pendidikan, dan juga wisata ekonomi.Kata kunci: BMC, Mangrove Jawa Timur, Produk Mangrove

Rajungan (Portunus pelagicus) merupakan salah satu komoditas perikanan yang memiliki nilai ekonomis penting yang ditangkap dengan alat tangkap pasif, seperti bubu lipat. Penggunaan celah pelolosan pada bubu diharapkan mampu memenuhi ukuran rajungan yang diperbolehkan untuk ditangkap sebagaimana yang tertulis pada Peraturan Menteri Kelautan dan Perikanan 12/2020 (lebar karapas >10 cm). Tujuan dari penelitian ini adalah untuk mengetahui ukuran celah pelolosan yang sesuai untuk meloloskan rajungan dengan lebar karapas 10 cm serta mampu menahan rajungan dengan lebar karapas >10 cm. Sebanyak 30 ekor rajungan dengan lebar karapas 9-10,8 cm diuji cobakan terhadap tiga ukuran celah pelolosan yang berbeda (4,6 x 2,6 cm; 5 x 3 cm; dan 7 x 2,5 cm), dengan tiga kali ulangan. Uji coba dilaksanakan di laboratorium pada bulan Maret 2020. Hasil penelitian menunjukkan bahwa tidak ada perbedaan tingkat pelolosan rajungan pada ketiga ukuran celah pelolosan. Meski demikian, ukuran 4,6 x 2,6 cm diyakini merupakan ukuran yang paling efektif karena mampu meloloskan rajungan dengan lebar karapas 10 cm (46,9%), serta paling bagus dalam menahan rajungan dengan lebar karapas >10 cm tetap berada di dalam bubu. Percobaan lapang terhadap ukuran celah pelolosan ini pada beberapa perairan diperlukan untuk mengkonfirmasi penggunaannya pada perikanan rajungan.The blue swimming crab (Portunus pelagicus, BSC) is one of fishery commodities caught by passive gears, such as collapsible traps. The use of escape-vent on traps was supposed to comply with the legal size of BSC’s catch declared in the Ministerial Decree 12/2020 (i.e. >10 cm of carapace width). To determine an appropriate escape-vent size which is able to release BSC of 10 cm Carapace Width (CW) and to retain BSC of > 10 cm CW, 30 samples of BSC were tested on three different sizes of escape-vent (4.6 x 2.6 cm; 5 x 3 cm; and 7 x 2.5 cm) with three replications of each size. The results show that there was no significant difference of BSC’s escape rate among the escape-vent sizes. However, the size of 4.6 x 2.6 cm was assumed as the most effective escape-vent as it could release BSC of 10 cm CW (46.9%), and best to retain BSC of >10 cm CW inside the trap compared to other sizes. Field investigation might be needed to confirm the effect of the appropriate escape-vent size of collapsible trap on BSC fishery.

Personality is the life of a person as a whole, individually, unique, effort to achieve goals, ability to survive and open up, ability to gain experience. This personality is influenced by the use of the three personality systems in Sigmund Freud's theory, namely the id, ego, and superego. There are three research problem formulations, namely (1) How is the personality aspect related to the main character Diva's id in the novel "Muhasabah Cinta" by Dini Fitria, (2) How is the personality aspect related to Diva's main character's ego in the novel "Muhasabah Cinta" by Dini Fitria, (3) How is the personality aspect related to the main character superego Diva in the novel "Muhasabah Cinta" by Dini Fitria. The purpose of this study are (1) Describe the personality aspects related to the main character id Diva in the novel "Muhasabah Cinta" by Dini Fitria, (2) Describe the aspects of personality related to the main character Diva in the novel "Muhasabah Cinta" by Dini Fitria , (3) Describe the personality aspects related to the main character superego Diva in the novel "Muhasabah Cinta" by Dini Fitria. This research uses descriptive qualitative method using Sigmund Freud's personality psychology approach. The object of this research is the psychological aspect which is focused on the personality of the main character of Diva according to Sigmund Freud's personality theory. The data source used in this study is the novel: "Muhasabah Cinta". Data collection techniques in this study are note-taking techniques. The data that has been collected is then processed and analyzed through several stages, namely the heuristic reading stage by interpreting the text and the hermeneutic reading stage by interpreting the meaning.

Goatfish is one of the most dominant demersal-fish species currently caught by local fishermen in North-Coast of East Java and Madura using modified Danish-Seine. This research aimed to investigate species diversity goatfish and spawning potential ratio (SPR) of most representative species, U. suphureus. Identification was completed through morphometric and meristic investigation. A total of 2,550 fish were sub-sampled from catches for length-frequency analysis, length at first maturity (Lm), length-weight relationship and SPR. The results showed that there were five species within catches, being: U. sulphureus, U. moluccensis, U. tragula, U. sundaicus, and P. heptacanthus. Length-weight followed cubic formula with Wt = 0.0159 * Lt3.124 (p< 0.05; r2 = 0.92). Female length-at-first mature was reached at 11.67 cm Fork-Length, with total female biomass in the sample 6.5 kg. Total biomass was 93.1 kg, hence the SPR was < 7%. The minimum value of SPR while maintaining stock at good parent stock was >20%. From these results, it was very clear that demersal fishery in North-Coast of East Java, represented by U. sulphureus is unsustainable. Management measure, either size or effort limitation should be implemented, otherwise, the stock will soon collapse.

Tropical peatlands in Indonesia have been disturbed over decades and are a source of carbon dioxide (CO2) into the atmosphere by peat respiration and peatland fire. With a portable solar spectrometer, we have performed measurements of column-averaged CO2 dry-air molar mixing ratios, XCO2, in Palangka Raya, Indonesia, and quantify the emission dynamics of the peatland with use of the data for weather, fire hotspot, ground water table, local airport operation visibility and weather radar images. Total emission of CO2 from surface and underground peat fires as well as from peatland ecosystem is evaluated by day-to-day variability of XCO2. We found that the peatland fire and the net ecosystem CO2 exchange contributed with the same order of magnitude to the CO2 emission during the non-El Niño Southern Oscillation year of July 2014-August 2015.
