Mengatasi Cemaran Getah Kuning Pada Buah Manggis (Garcinia Mangostana) Dengan Aplikasi Kalsium Dan Teknologi Lubang Resapan Biopori

Cemaran getah kuning pada buah manggis akan menurunkan kualitas buah. Cemaran getah kuning terjadi pada saat getah mencemari permukaan kulit buah atau aril akibat pecahnya saluran getah kuning. Pecahnya saluran getah kuning berkaitan dengan keberadaan kalsium dalam pericarp buah. Penelitian ini bertujuan untuk (1) mendapatkan dosis dan sumber kalsium terbaik dan efisien dalam menurunkan cemaran getah kuning pada buah manggis, (2) mengetahui pengaruh lubang resapan biopori di dalam USAha mengatasi cemaran getah kuning pada buah manggis, dan (3) mengetahui kombinasi terbaik dari aplikasi kalsium dan lubang resapan biopori untuk meningkatkan serapan dan translokasi kalsium ke buah dan dapat menanggulangi cemaran getah kuning pada buah manggis. Hasil penelitian ini menunjukkan: (1) pemberian kalsium, baik bersumber dari dolomit maupun kalsit, mampu menurunkan cemaran getah kuning pada aril maupun kulit buah manggis, (2) berdasarkan efisiensi dan efektifitas maka dosis pupuk kalsium sebesar 1,6 kg kalsium kalsit/pohon/tahun menjadi dosis terbaik dalam mengatasi cemaran getah kuning, (3) teknologi lubang resapan biopori dapat meningkatkan pertumbuhan dan perkembangan akar muda yang selanjutnya dapat meningkatkan serapan kalsium dan menurunkan cemaran getah kuning setelah 2 tahun aplikasi, (4) kombinasi 1,6 kg kalsium kalsit/pohon/tahun dengan teknologi lubang resapan biopori (LRB) merupakan teknik yang efektif dan mampu meningkatkan persentase produksi buah manggis berkualitas bebas cemaran getah kuning

Data from an International Multi-Centre Study of Statistics and Mathematics Anxieties and Related Variables in University Students (the SMARVUS Dataset)

This large, international dataset contains survey responses from N = 12,570 students from 100 universities in 35 countries, collected in 21 languages. We measured anxieties (statistics, mathematics, test, trait, social interaction, performance, creativity, intolerance of uncertainty, and fear of negative evaluation), self-efficacy, persistence, and the cognitive reflection test, and collected demographics, previous mathematics grades, self-reported and official statistics grades, and statistics module details. Data reuse potential is broad, including testing links between anxieties and statistics/mathematics education factors, and examining instruments’ psychometric properties across different languages and contexts. Data and metadata are stored on the Open Science Framework website [https://osf.io/mhg94/]

Pengolahan Limbah Cair Industri Jamu Dan Farmasi Menggunakan Anaerobic Baffled Reactor Secara Shock Loading Dalam Upaya Menghasilkan Biogas

PT. Sidomuncul is one of the factories that produce waste. Wastewatergenerated at 130m3 per day. Because of the big amount of wastewater produced, it is necessary to accommodate a short in time wastewater processing, that won\u27t required a large area and much time. Wastewater processing results of PT. Sidomuncul has a COD value of about 15000 mg /l. Wastes with high levels of COD is well treatedby anaerobically better than aerobic. Anaerobic wastewater treatment can be done if the value of minimal COD is 1500mg /l. This research will try to process the wastewater anaerobically by shockloading method using activated sludge. The purpose of this study was to determine the activated sludgestability when it is done with shock loading method and also the effect of COD level and biogas production as changed variables such rector design, HRT, activated sludge type, and activated sludge height. Observed responses are pH effluent, COD levels, and gas production. The results of this research are the process of anaerobic wastewater shock loading on herbal medicine and pharmaceutical industry could reduce COD levels ranged from 78.46% to 93.97% and produce biogas at it\u27s best using organic fertilizer sludge with 1/3 height of ABR
