Abstract

The purpose of this study was to use the Sports Policy Factors Leading to International Sporting Success (SPLISS 2.0) instrument and the nine pillars of elite sports success approach to survey and assess the success factors of coaching. Athletes from eight districts or cities in Central Java that had paragliding organizations, as well as chairs, secretaries, treasurers, and coaches were included in the survey. Data were analyzed through SPLISS 2.0 reports and quantitative analysis methods. Potential success factors were determined quantitatively using 96 CSFs assigned to a score of 0-1 based on nine pillars. Findings show that Banyumas, Grobogan, the Semarang district, and Karanganyar are the four regions offering the highest numbers of paragliding sports. The districts of Grobogan and Semarang are best in participation, talent identification, and talent development. The results show that many regions have yet to adopt the nine pillars. It is intended that each region would produce paragliding athletes of the highest caliber, honoring Central Java and Indonesia as a country. [ABSTRACT FROM AUTHOR]

Abstract

Composites of manganese and nitrogen-codoped zirconium titanate (Mn,N-codoped ZrTiO4) had been synthesized by the sol-gel method as a visible-light responsive photocatalyst for the photodegradation of methylene blue (MB). Synthesis was conducted at 25 °C using titanium(IV) isopropoxide, zirconium oxide, urea, and manganese(II) chloride. Mn,N-codoped ZrTiO4 containing fixed 10% nitrogen dopant (wN/wTi) with various Mn dopant contents (2, 4, 6, 8, and 10% wMn/wTi) and calcination temperatures (500, 700, and 900 °C) had been investigated. All of the Mn,N-codoped ZrTiO4 exhibit a band gap within the visible range (2.51 to 2.74 eV). Photodegradation of MB was performed under visible light illumination for 120 min. The highest activity was achieved up to 7.7 µg L−1 min−1, which was obtained from Mn,N-codoped ZrTiO4 calcined at 500 °C containing 6% Mn and 10% N dopants.

Abstract

Iron (Fe) and nitrogen (N) were introduced as dopants into zirconium titanate (ZrTiO4) in order to study the codoping effects of nitrogen on iron-doped zirconium titanate (Fe,N-codoped ZrTiO4) composite. Titanium tetraisopropoxide (TTIP), zirconia (ZrO2), urea, and iron(II) sulfate heptahydrate were used as the source of TiO2, semiconductor supports, source of nitrogen, and iron, respectively. A specific amount of iron (1, 3, 5, 7, and 9 wt.%) and a fixed nitrogen content (10 wt.%) were doped into the ZrTiO4 lattice. Various calcination temperatures (from 500 to 900 °C) were also applied to investigate the crystal structure of the composite. The composites were characterized by X-ray powder diffractometer (XRD), Fourier-transform infrared spectrophotometer (FT-IR), scanning electron microscope with energy dispersive X-Ray spectrometer (SEM-EDX), and specular reflectance UV-Vis (SR-UV). The lowest bandgap energy of 2.62 eV was obtained in the composite with 3 wt.% of Fe and 10 wt.% of N calcined at 500 °C.

Abstract

Skripsi berjudul “Ayah Lebih Utama Dibandingkan Ibu Dan Dalam Penetapan Hadhanah (Analisis Putusan Nomor 0050/Pdt.G/2019/ Pengadilan Agama Lubuk Pakam) Untuk menjawab dua masalah: Pertama, Bagaimana Penetapan Hadhanah Menurut Kompilasi Hukum Islam dan Mazhab Syafi’i ?, kedua Mengapa ayah lebih utama dibandingkan ibu dalam Penetapan Hadhanah Menurut Putusan Nomor 0050/pdt.G/2019/ Pengadilan Agama Lubuk Pakam ? Data penelitian dikumpulkan dengan membaca putusan dan wawancara dengan hakim yang terlibat langsung dalam putusan perkara: 0050/Pdt.G/2019/PA.Lpk, kemudian dianalisis menggunakan metode deskriptif analitis menggunakan mazhab KHI dan Syafi'i. penelitian ini adalah Kesimpulan: Pertama, Menganalisis dari putusan nomor 0050/Pdt.G/2019 Pengadilan Agama Lubuk Pakam Ayah lebih utama dibandingkan ibu dan keluarga ibu dalam penetapan Hadhanah, dikarenakan ibu disebutkan sebagai tergugat pada putusan tersebut telah menikah lagi dengan seorang lelaki bahkan telah melahirkan seorang anak pada tanggal 28 Mei 2018 di Rumah Sakit Stella Maris Medan. Kedua, Menganalisis dari putusan nomor 0050/Pdt.G/2019 Pengadilan Agama Lubuk Pakam Ayah lebih utama dibandingkan ibu dan keluarga ibu dalam penetapan Hadhanah, dikarenakan ibu disebutkan sebagai tergugat pada putusan tersebut telah berkelakuan buruk secara berlebihan dan terbuka, sejak september 2015 bahwa tergugat telah menyerahkan anaknya kepada penggugat dalam pemeliharaan hak hadhanah, bahwa tergugat telah berkelakuan buruk dengan tidak menjalankan handhanahnya. Ketiga, Menganalisis berdasarkan pasal 156 (c) kompilasi hukum islam “Jika jelas bahwa pemegang hahanah tidak dapat menjamin keselamatan fisik dan mental anak, bahkan jika biaya hidup dan hadhanah telah telah dibayar, maka dalam yang bersangkutan Atas permintaan seorang kerabat, Pengadilan Agama dapat mengalihkan hak hadhanah kepada kerabat lain yang mempunyai hak hadhanah pula”. Menganalisis berdasarkan bukti saksi yang diajukan Penggugat, yang menyatakan bahwa Peng

Abstract

Electronic waste (e-waste) has been confirmed containing some precious metals such as gold and silver. Mangosteen peel waste as eco-friendly adsorbent has been studied to recover Au(III) and Ag(I) successfully. Recovery was started through adsorbent preparation, consisting of soxhlet extraction and maceration. About 100 mg of adsorbent was dispersed into Au(III) and Ag(I) solutions in various pH conditions (2–6). The result proves that the optimum adsorptions of Au(III) and Ag(I) are at pH 2 and pH 6, respectively. Au(III) adsorption follows the isotherm model of Langmuir with a maximum capacity of 0.580 mmol/g (114.27 mg/g). Ag(I) adsorption follows the isotherm model of Freundlich with a maximum capacity of 0.511 mmol/g (55.10 mg/g).
