Abstract

Pengelolaan sampah organik di lingkungan kampus menjadi tantangan utama karena tingginya volume limbah biodegradable yang dihasilkan. Penelitian ini bertujuan untuk mengoptimalkan kelembaban dalam proses biodegradasi sampah organik menggunakan larva Black Soldier Fly (BSF) atau maggot di Kampus Universitas PGRI Argopuro (UNIPAR). Penelitian dilakukan dengan pendekatan eksperimental menggunakan Rancangan Acak Lengkap (RAL) dengan lima tingkat kelembaban (40%, 50%, 60%, 70%, dan 80%). Variabel yang diamati meliputi efisiensi penguraian sampah organik dan kualitas kompos (C/N ratio, pH, dan kandungan unsur hara). Data dianalisis menggunakan ANOVA satu arah dan uji post-hoc Tukey. Hasil menunjukkan bahwa tingkat kelembaban 80% memberikan efisiensi penguraian tertinggi sebesar 62% serta menghasilkan kompos berkualitas terbaik dengan C/N ratio 17:1, pH 7.5, dan kandungan unsur hara (N: 1.9%, P: 0.8%, K: 1.2%). Hubungan linier positif antara kelembaban dan efisiensi/kualitas kompos mengindikasikan bahwa kelembaban adalah faktor kunci dalam keberhasilan pengelolaan sampah menggunakan maggot BSF. Penelitian ini mendukung penerapan metode maggot BSF sebagai solusi pengelolaan limbah organik yang efisien dan ramah lingkungan di kampus UNIPAR, dengan potensi manfaat tambahan berupa produk kompos berkualitas tinggi untuk mendukung pertanian berkelanjutan.

Abstract

Pengelolaan sampah organik merupakan tantangan penting dalam pengelolaan limbah domestik, terutama di Indonesia, di mana lebih dari 50% sampah terdiri dari limbah organik yang sering kali tidak terkelola dengan baik. Salah satu solusi yang menjanjikan adalah penggunaan maggot Black Soldier Fly (Hermetia illucens) dalam penguraian sampah organik. Keberhasilan proses ini sangat bergantung pada faktor lingkungan, khususnya suhu dan kelembaban, yang dapat memengaruhi laju pertumbuhan dan efisiensi penguraian maggot. Penelitian ini bertujuan untuk menganalisis pengaruh suhu dan kelembaban terhadap pertumbuhan maggot dan penguraian sampah organik. Metode yang digunakan adalah eksperimen dengan desain Rancangan Acak Lengkap (RAL), dengan perlakuan kelembaban (60%, 70%, 80%) dan suhu (25°C, 30°C, 35°C). Hasil penelitian menunjukkan bahwa kombinasi suhu 30°C dan kelembaban 80% menghasilkan bobot maggot tertinggi (1,2 g) dan volume sampah terurai tertinggi (60,2%). Hasil analisis ANOVA dua arah menunjukkan bahwa suhu dan kelembaban memiliki pengaruh signifikan terhadap kedua parameter tersebut, dengan interaksi antara suhu dan kelembaban yang juga berpengaruh. Penelitian ini memberikan rekomendasi bahwa kondisi optimal untuk pertumbuhan maggot dan penguraian sampah organik adalah suhu 30°C dan kelembaban 80%, yang dapat digunakan untuk pengelolaan sampah organik yang lebih efisien di lingkungan tropis.

Abstract

Indonesia is the second rubber producer in the world, in its processing rubber produces liquid waste that contains quite high ammonia levels. This study aims to provide an alternative solution to the problem of water pollution due to ammonia in rubber industry liquid waste using a bioremediation process with a simple bioreactor. This study used indigenous fungi treatment of 4% and banana peel extract of 0%, 5%, and 10%. This study studies the potential of indigenous fungi with banana peel extract nutrients to reduce ammonia levels in water. The parameter measured is the level of ammonia in the water in the bioreactor. The results showed that indigenous fungi with banana peel extract nutrients had an effect on ammonia parameters. Treatment with a concentration of indigenous fungi 4% and banana peel extract 10% had a significant effect on reducing ammonia levels. The more indigenous fungi inoculum and banana extract used, the more effective it is in reducing ammonia in water.

Abstract

The increasing global demand for food has driven the development of environmentally friendly technologies in agriculture, one of which involves the use of nitrogen-fixing bacteria-based biofertilizers. This study aims to evaluate the effectiveness of two nitrogen-fixing bacterial species, Azotobacter chroococcum and Beijerinckia indica, in enhancing the growth of red spinach (Alternanthera ficoidea) in acidic soil conditions. The results revealed that treatments with various concentrations of bacterial inoculants did not have a statistically significant effect on plant height, based on a two-way ANOVA test (α > 0.05). However, descriptively, B. indica demonstrated more optimal performance compared to A. chroococcum and their combination, particularly at a concentration of 15 mL, which produced the highest plant height (31.00 cm). B. indica exhibited better survival and functionality in acidic soil (pH 4–4.5), whereas A. chroococcum was less efficient under such conditions. These findings underscore the importance of selecting bacterial strains that are compatible with specific soil characteristics to enhance the efficacy of biofertilizers and support the growth of ornamental plants such as A. ficoidea.

Abstract

Banana peels, a by-product of banana consumption, remain underutilized despite their promising bioactive potential. This study aims to assess the antibacterial properties of the peel extract from the Agung banana variety (Musa paradisiaca var. sapientum L.) against two pathogenic bacterial strains: Pseudomonas aeruginosa and Staphylococcus aureus. The extract was prepared through a maceration method, and antibacterial activity was tested using the disk diffusion technique. A Completely Randomized Design (CRD) was employed, involving five concentration levels (0%, 25%, 50%, 75%, and 100%) with four replicates each. Data were analyzed using ANOVA, followed by Duncan’s Multiple Range Test (DMRT) to determine significant differences between treatments. The results demonstrated that the Agung banana peel extract significantly inhibited the growth of both test bacteria. The 100% concentration yielded the largest inhibition zones, with mean diameters of 17.55 ± 3.39 mm for P. aeruginosa and 19.25 ± 0.91 mm for S. aureus. According to the classification of antibacterial strength, these results are considered strong. These findings suggest that the Agung banana peel has considerable potential as a natural and eco-friendly antibacterial agent.
