Garbage is a problem that has not been resolved until now. The central and local governments have tried to make regulations on waste management and have disseminated them to the public, but the waste problem still cannot be resolved. Community concern for the environment plays an important role in overcoming this problem. Starting from the smallest scope, namely the family or household to get used to managing waste properly and correctly. Household waste, especially kitchen waste, can be used as compost. The processing of household waste into compost can be done individually or in groups such as at the RT level. This community service aims to provide counseling about the importance of maintaining environmental cleanliness and the use of household kitchen waste as compost. The activity is intended for residents of Jalan Agus Salim RT 18, Sungai Pinang Luar District, Samarinda. The method used is counseling followed by demonstration of composting, pre-test and post-test are also carried out to determine the level of community understanding of this community service activity. This activity was attended by the head of the RT and several residents as representatives of the residents of the RT. The existence of this activity is expected to change people's behavior to be better in managing waste and become a source of income for residents.

Sejak terjadinya pandemi covid 19 ketersediaan hand sanitizer di Indonesia menjadi sangat langka di pasaran, dikarenakan banyak orang yang membeli barang tersebut secara berlebihan. Pemerintah menghimbau kepada masyarakat untuk selalu menjaga kebersihan tangan dengan rajin mencuci tangan menggunakan sabun atau menggunakan hand sanitizer sebagai salah satu upaya mencegah penularan covid 19. Pembersih tangan (hand sanitizer) memiliki kemampuan menghambat hingga membunuh bakteri. Tujuan dilakukannya pengabdian masyarakat ini adalah memberikan pelatihan kepada masyarakat cara membuat hand sanitizer dari bahan sintetis dan bahan alam. Formula hand sanitizer dari bahan sintetis berupa alkohol 96%, hydrogen peroksida, gliserin dan aquades. Sedangkan formula hand sanitizer dari bahan alam berupa daun sirih, jeruk nipis dan aquades. Kegiatan ini merupakan kerjasama antara Dinas Perindustrian, Perdagangan, Koperasi, Usaha Kecil dan Menengah Provinsi Kalimantan Timur dengan Sekolah Tinggi Ilmu Kesehatan Samarinda. Peserta pada kegiatan ini adalah perwakilan warga Kelurahan Karang Asam Ilir, Kelurahan Sempaja Utara dan Kelurahan Sungai Kapih. Metode yang digunakan pada pengabdian masyarakat meliputi ceramah tentang pentingnya menjaga kebersihan tangan, pengertian hand sanitizer, uraian bahan yang digunakan, dilanjutkan demonstrasi dan bimbingan. Kegiatan ini didanai oleh Desperidagkop UKM Provinsi Kalimantan Timur. Harapan dengan dilaksanakan pelatihan ini ialah masyarakat dari kelurahan yang menjadi peserta lebih peduli dengan kebersihan dan dapat memenuhi kebutuhan hand sanitizer untuk keluarga dan masyarakat sekitarnya.

Syzygium jambos is a medicinal plant. This study aims to determine the effect of variations in ethanol concentration on yield of guava leaf extract by maceration method. The research conducted was experimental research. The research phase includes sample collection, determination, manufacture of simplicia, extraction by maceration with variations in ethanol concentration, determination of yield, phytochemical screening and determination of drying losses. Phytochemical screening results showed that 50% of ethanol extracts of positive rose guava contained flavonoids, tannins, saponins and steroids / terpenoids, 70% ethanol and 90% positives contained flavonoids, tannins and steroids / terpenoids. The yield of rose guava ethanol extract was 50% (23.01% ± 0.372), 70% ethanol (21.96% ± 1.181) and 90% ethanol (16.57% ± 0.384). LSD test results showed a significant difference (p

Akar KB (Coptosapelta tomentosa Valeton ex K. Heyne) secara empiris digunakan sebagai obat keputihan, namun data penelitian terkait akar KB belum dilakukan. Hal ini yang menyebabkan akar KB belum terbukti secara ilmiah. Tujuan penelitian ini adalah untuk mengetahui aktivitas ekstrak etanol akar KB terhadap salah satu fungi penyebab keputihan yakni Candida albicans serta mengetahui berapa konsentrasi hambat minimum ekstrak etanol akar KB yang mampu menghambat pertumbuhan Candida albicans. Akar KB mengandung senyawa fitokimia antara lain alkaloid, flavonoid dan saponin. Senyawa antifungi yang terdapat dalam akar KB diekstraksi dengan metode maserasi menggunakan pelarut etanol 70%. Hasil ekstraksi dipekatkan hingga menjadi pasta dan dibuat konsentrasi 10%, 20%, 30%, 40% (b/v). Ekstrak diujikan pada Candida albicans menggunakan metode difusi agar (sumuran) dengan mengukur zona hambat yang terbentuk. Ketokonazol 0,1% sebagai kontrol positif dan akuades sebagai kontrol negatif. Hasil penelitian menunjukkan bahwa ekstrak etanol akar KB pada semua konsentrasi efektif terhadap Candida albicans. Konsentrasi hambat minimum terhadap Candida albicans adalah 10% (b/v) dengan diameter zona hambat 12,98 mm. Hasil analisis data menggunakan SPSS menunjukan bahwa varian data homogen dan terdapat perbedaan bermakna pada setiap perlakuan uji.

Antioxidant activity, total phenolic and flavonoid content of several indigenous species of ferns in East Kalimantan, Indonesia. Biodiversitas 20: 576-580. This study aimed to determine the total phenolic and flavonoids content and antioxidant activity of ethanol extract of several indigenous species of ferns in East Kalimantan. Total phenolic content was determined by Folin-Ciocalteau method and flavonoid content was measured by colorimetric method. Antioxidant activity was evaluated by DPPH (2,2-diphenyl-1-picrylhydrazyl) method. The result of photochemical screening indicated that the leaves of Plagiogyria pycnophylla, Plagiogyria glauca, and Stenochlaena palustris contained alkaloid, flavonoid, tannin, saponin, and steroid while Acrostichum aureum contained flavonoid, tannin, saponin and steroid. The result showed extract Acrostichum aureum had the highest total phenolic content (366.4573 ± 2.2117 mg GAE.g-1), flavonoid content (228.6087 ± 2.2548 mg QE.g-1), and very strong antioxidant activity with IC50 value 29.5303 ppm. There is positive correlation between total phenolic content, flavonoid with antioxidant activity.
