Pemanfaatan Mikro Organisme Lokal (MOL) pada Pembuatan Pupuk Organik Cair (POC) dengan Memanfaatkan Limbah Sayuran
No full textThis study aims to analyse the Nitrogen and pH levels of liquid organic fertiliser (LOF) made using microlocal organisms (LMO) based on vegetable waste. The method used was an experimental method through a fermentation process carried out at the Center for Standardisation and Industrial Pollution Prevention Services (BBSPJPPI). The results showed that the LOF produced had a Nitrogen content of 0.03% and a pH of 3, which did not meet the quality standards of liquid organic fertiliser in Indonesia, namely Nitrogen content of 2-6% and a neutral to slightly acidic pH (5-7). The low Nitrogen content is due to the Nitrogen-poor composition of the vegetable waste, while the overly acidic pH is due to the prolonged fermentation time, which triggers the formation of organic acid compounds. To improve the quality of LOF, optimisation is needed in the selection of raw materials, fermentation ratio, and control of fermentation parameters such as time and temperature. This research provides recommendations for the development of higher-quality LOFs that comply with national standards.Tujuan penelitian artikel ini untuk menganalisis kadar Nitrogen dan pH dari pemanfaatan Mikro Organisme Lokal pada pembuatan Pupuk Organik Cair. Bersumber pada hasil penelitian dapat ditarik kesimpulan bahwa Pupuk Organik Cair yang dibuat menggunakan limbah sayuran dengan persentase kadar Nitrogen 0,034 belum memenuhi standar mutu Pupuk Organik Cair yang ditetapkan pemerintah Indonesia yaitu kandungan N berkisar 2-6%. Kandungan pH yaitu 3 yang berarti asam karena dekomposisi bahan organik. Penurunan pH yang begitu rendah dapat dipengaruhi oleh waktu fermentasi Mikro Organisme Lokal yang terlalu lama

Potensi Penerapan Teknologi Aerobic Granular Sludge (AGS) dalam Pengolahan Air Limbah Industri Tahu
No full textThe tofu industry produces high protein food but produces wastewater with high organic matter and ammonia which is the result of protein breakdown in soybean seeds during the extraction process. Small and Medium Enterprises (SMEs) sometimes neglect waste treatment due to limited resources. Indonesian regulations stipulate special quality standards for wastewater in the Regulation of the Minister of Environment of the Republic of Indonesia No. 5 of 2014 concerning Wastewater Quality Standards for Soybean Processing Businesses and/or Activities. Indicators of organic matter pollution are characterized by the parameters BOD 150 mg/l, COD 300 mg/l, TSS 200 mg/l, and pH 5-9. Meanwhile, tofu industrial wastewater without special treatment can exceed the quality standard with BOD levels of 5.000-10.000 mg/l and COD levels of 7.000-12,000 mg/l. To overcome this problem apart from using activated sludge, researchers are exploring the use of Aerobic Granular Sludge (AGS) technology. AGS involves aggregate microorganisms in granules to treat wastewater efficiently. This increases treatment efficiency, reduces space requirements, and handles high organic loads effectively. Although aerobic granular technology is promising, research is still ongoing to better understand its characteristics and optimize applications in various industries and environmental conditions. This study aims to explore the potential application of Aerobic Granular Sludge (AGS) technology in treating tofu industrial wastewater with high organic matter content and significant ammonia content so that it meets permitted quality standards.Industri tahu menghasilkan makanan dengan kandungan protein tinggi, tetapi juga menghasilkan air limbah yang mengandung bahan organik dan amonia tinggi yang merupakan hasil pemecahan protein dalam biji kedelai selama proses ekstraksi. Usaha Mikro, Kecil, dan Menengah (UMKM) kadang-kadang mengabaikan pengolahan limbah karena keterbatasan sumber daya. Peraturan di Indonesia menetapkan standar kualitas khusus untuk air limbah dalam Peraturan Menteri Lingkungan Hidup Republik Indonesia No. 5 Tahun 2014 tentang Baku Mutu Air Limbah bagi Usaha dan/atau Kegiatan Pengolahan Kedelai. Indikator pencemaran bahan organik ditandai dengan parameter BOD 150 mg/l, COD 300 mg/l, TSS 200 mg/l, dan pH 5-9. Sementara itu, air limbah industri tahu tanpa pengolahan khusus dapat melebihi standar kualitas dengan kadar BOD antara 5.000-10.000 mg/l dan kadar COD antara 7.000-12.000 mg/l. Untuk mengatasi masalah ini, selain menggunakan lumpur aktif, para peneliti juga sedang mengeksplorasi penggunaan teknologi Aerobic Granular Sludge (AGS). AGS melibatkan mikroorganisme dalam bentuk agregat granula untuk mengolah air limbah secara efisien. Teknologi ini meningkatkan efisiensi pengolahan, mengurangi kebutuhan ruang, dan mampu menangani beban organik tinggi secara efektif. Meskipun teknologi granular aerobik menjanjikan, penelitian masih terus dilakukan untuk lebih memahami karakteristiknya dan mengoptimalkan aplikasinya dalam berbagai industri dan kondisi lingkungan. Penelitian ini bertujuan untuk mengeksplorasi potensi penerapan teknologi Aerobic Granular Sludge (AGS) dalam mengolah air limbah industri tahu yang mengandung bahan organik tinggi dan kandungan amonia yang signifikan sehingga memenuhi standar kualitas yang diizinkan

Exploring the Relationship between Logical Reasoning Skills, Scientific Literacy, and Academic Achievement in Science Courses Among Secondary Students: A Mixed Method Study
No full textThis study explores the correlation between Scientific Literacy (SL) results from PISA 2015 released items, the Test of Logical Thinking (TOLT), and Science Score Achievement (SSA). The method of this study used an explanatory sequential research design with cross-sectional and convenience sampling. Ninety-two 15-year-old students and science teachers participated. The correlation between SL, TOLT, and SSA was positive but moderately weak. The average SL score was low at 33.04%. TOLT results showed that 64.13% of students demonstrated concrete reasoning, 32.61% proportional reasoning, and 3.26% formal reasoning. SSA scores averaged 81.90, with 53 students scoring above average. Interviews with teachers suggested low SL and LT scores resulted from a lack of hands-on activities, as teachers relied heavily on lectures. Science textbooks also lacked inquiry-based learning tasks. The limitations of this research are that it does not cover gender comparison, school curriculums, or school locations, whether urban or suburban. The psychological aspects regarding the students’ interest or efficacy are not included in the discussion or provided. Also, students with positive learning experiences in science have good results in SL, and TOLT has not been proven empirically
