Abstract

Indonesia is the 4th most populous country in the world. The main factors influencing the high rate of urban population growth are urbanization and migration. This condition causes an increase in the amount of waste generation, whether solid, liquid or gas waste. Therefore, efforts are needed to manage and process waste generation, one of which is composting. Composting is a form of reuse and recovery of resources from solid waste by decomposing organic matter with the help of organisms. One of the organisms that can be used as a waste decomposition agent is the Black Soldier Fly larvae. The composting process requires several requirements to produce good quality compost, namely the content of macro nutrients, namely N, P, K. This research was conducted on 3 February – 2 March 2022 at the Sahabat Alam Waste Bank (SAWB) Kp. Apar, South Pariaman, Pariaman City, West Sumatra. Sample testing was carried out at the Chemistry Laboratory of FMIPA UNP using the levels of Nitrogen (N) (Kjehdahl Method), Phosphorus (P) and Potassium (K) (X-Ray Fluorescence Method). The quality of N, P, K solid compost obtained from this study was nitrogen levels 6.09% (S.Week 1) and 9.324%, phosphorus levels 8.113% (S.Week 1) and 6.176% (S.Week 2), and 29.759% (S.Week 1) and 38.181% (S. .Week 2) for potassium levels.

Abstract

Operasional dari PLTU ini akan memberikan dampak terhadap kualitas air disekitarnya. Salah satunya gangguan biota air. Dengan adanya pembongkaran batu bara di laut sebagai bahan bakar dan juga adanya pembuangan air bahang ke laut, kegiatan ini tentunya berdampak terhadap makrozoobentos. Penelitian ini bertujuan untuk menganalisa kualitas air berdasarkan eksistensi komunitas makrozoobentos dan menganalisa factor fisika kimia air. Penelitian ini menggunakan metode survey dan pengkoleksian langsung. Lokasi pengambilan sampel terdiri dari 2 titik sampel yaitu di inlet dan outlet PLTU Teluk Sirih dengan 3 kali ulangan pada masing-masing stasiun. Hasil penelitian ditemukan makrozoobentos sebanyak 16 jenis terdiri dari jenis Bivalvia, 7 jenis Gastropoda, 2 jenis Malacostraca, dan 6 jenis masuk dari kelas Polychaeta. Kepadatan populasi bentos pada outlet adalah 429 ind/m2 sedangkan kepadatan pada inlet adalah 528 ind/m2. Indeks keanekaragaman pada titik outlet yaitu 2,815 dan inlet adalah 2,727. Berdasarkan indeks keanekaragaman makrozoobentos, maka kondisi perairan Teluk Sirih dalam kondisi baik dan stabil. Berdasrkan indeks kemerataan menunjukan makrozoobentos tersebar merata dengan nilai mendekati 1, dan indeks dominansi mendekati nol, artinya tidak ada makrozoobentos yang mendominasi. Kualitas air seperti kecerahan dan Total suspense Solid (TSS) menunjukan kualitas air bersih dan jernih, suhu didapatkan 24,6 dan 24,7oC, pH berkisar dari 7,76-8,18, Salinitas 19,2 ‰ dan Total Organik Karbon (TOK) 62,5-62,6 mg/L.

Abstract

The management of rice straw (Oryza sativa) waste in Indonesia, particularly in Pasaman Regency, faces significant challenges due to the widespread practice of open burning, which harms the environment and poses health risks to local communities. Despite this, rice straw holds great potential as an organic compost material that is environmentally friendly and nutrient-rich. This study explores the use of Rhizopus oryzae, a fermentation fungus capable of accelerating the decomposition of rice straw, as an efficient, economical, and sustainable waste management solution. Through fermentation, rice straw can be converted into high-quality compost that enhances soil fertility and agricultural productivity while reducing dependence on chemical fertilizers. This technology is highly relevant in promoting sustainable agriculture and climate change mitigation by lowering greenhouse gas emissions. However, field adoption still faces challenges, particularly in fermentation control and farmer outreach. Therefore, policy support, technical training, and cross-sector collaboration are essential to ensure broad and effective implementation. This approach presents a strategic solution for environmentally friendly agricultural waste management and improving farmer livelihoods in the future.

Abstract

Mangosteen peel waste (Garcinia Mangostana L) is mixed with coffee grounds (Coffea Sp) to make compost, aiming to return organic matter to the soil and increase fertility. This study looks at the effectiveness of EM4 activator and dry leaves in composting mangosteen peel waste. There are two treatments: mangosteen peel, coffee grounds (KA), mangosteen peel, coffee grounds, dry leaves, EM4 (KADE). As a result, the addition of EM4 and dry leaves increases the composting speed in 31 days, using a C/N ratio reaching 4,79%, according to SNI stndards. The nutrient content in the compost also meets SNI 19-7030-2004 standards, using analysis providing levels of nitrogen, phosphorus, potassium, organic C, and water content thatare suitable for use. The study is recommended to beapplied to several types of plants in appropriate soil pH conditions. It is also recommended to make compost from mangosteen peel in the form of organic fertilizer.
