Abstract

ABSTRAK Penelitian ini bertujuan untuk mengestimasi emisi gas metana (CH4) dari proses pengomposan feses babi (sus scrofa domesticus) menggunakan effective microorganism-4 (EM4). Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dan 4 ulangan. Perlakuan terdiri dari yaitu K0: 100% Feses babi, K1: 100% Feses babi + EM4 konsentrasi 5%, K2: 100% Feses babi + EM4 konsentrasi 10%, K3: 100% Feses babi + EM4 konsentrasi 15%, K4: Feses babi 100% + EM4 konsentrasi 20%. Peubah yang diamati adalah suhu, kelembapan, pH, CH4 dan, penyusutan kompos. Data yang dihimpun dianalisis ragam dan apabila berpengaruh nyata, diuji menggunakan Uji DMRT. Hasil penelitian ini menunjukkan bahwa penambahan EM4 berpengaruh nyata (P< 0,05) terhadap suhu, kelembapan, pH, CH4 tetapi tidak berpengaruh nyata (P>0.05) terhadap penyusutan. Estimasi emisi gas CH4 dari proses pengomposan feses babi menggunakan EM4 untuk mitigasi emisi gas CH4 dengan menggunakan EM4 konsentrasi 10%.

Abstract

Corn straw has the potential as a ruminant feed, but is constrained by low crude protein so it must be combined with Indigofera zollingeriana legumes which have high crude protein. The addition of Indigofera zollingeriana at different levels is expected to increase the crude protein of corn straw silage (Zea mays) and is expected to produce good silage quality. This study aims to determine the physical quality of corn straw silage (Zea mays) and Indigofera zollingeriana in different proportions. The variables observed in this study were the percentage of shrinkage, pH value, percentage of moldy silage, fleigh value, and physical quality (color, aroma, and texture). This experiment was arranged in a Completely Randomized Design (CRD) with 3 treatments and each treatment was repeated 6 times, so there were 18 experimental units, namely P1 = 80% Corn straw + 15% Indigofera zollingeriana + 4% bran + 1% mineral mixture; P2 = 70% Corn straw + 25% Indigofera zollingeriana + 4% bran + 1% mineral mixture; P3 = 60% Corn straw + 35% Indigofera zollingeriana + 4% bran + 1% mineral mixture. The results of the analysis of variance test showed that corn straw silage (Zea mays) with a mixture of Indigofera zollingeriana had no significant effect (P>0.05) on the percentage of moldy silage, fleigh value, and physical quality (color, aroma, texture) but had a significant effect (P<0.05) on the percentage of shrinkage and pH of silage. Based on this study, it can be concluded that the best silage proportion was obtained in the P2 treatment with 70% corn straw + 25% Indigofera zollingeriana + 4% fine bran + 1% mineral mixture, resulting in good quality silage.

Abstract

Granular adsorbents are essential for fixed-bed column systems because they reduce the pressure drop and minimize the material loss commonly associated with powdered adsorbents. However, transforming powdered materials into mechanically stable granules without compromising their structural integrity remains a significant challenge. In this study, a granulated composite consisting of biochar, montmorillonite (MMT), and Zn/Al layered double hydroxide (LDH) was developed as a potential adsorbent for column application. Biochar derived from Avicennia marina biomass was combined with MMT and Zn/Al LDH to produce a composite material, which was subsequently granulated using bentonite, tapioca starch, and polyvinyl alcohol (PVA) as binding agents. The resulting granules (0.5–1.5 cm in diameter) were evaluated for mechanical durability under static water immersion and dynamic water flow conditions. The results indicate that the binder composition strongly influences granule stability. Granules prepared without PVA rapidly disintegrated in aqueous environments, whereas the inclusion of PVA significantly improved structural durability. The optimized formulation exhibited durability of up to 8208 min under static conditions and maintained its structural integrity under continuous water flow. These results demonstrate the potential of Biochar–MMT–Zn/Al LDH granules as durable adsorbents for fixed-bed column water treatment systems

Abstract

Acid mine drainage (AMD) represents a long-term environmental challenge originating from the oxidation of sulfide minerals and mobilization of dissolved metals into surrounding water systems. This study developed a comprehensive framework for AMD control that integrates drainage prevention strategies, hydraulic engineering, active and passive treatment technologies, monitoring systems, and sustainability principles into a unified approach. The framework synthesizes advances in geochemical mine planning, diversion and dewatering systems, hybrid chemical–biological treatment processes, and emerging technologies, including microbial electrochemical systems, selective metal recovery, and digital twins. A life cycle assessment was applied to evaluate environmental and economic trade-offs, emphasizing the potential for circular economy strategies that convert AMD byproducts into valuable resources. This review highlights the importance of adaptive management supported by real-time monitoring, stakeholder involvement, and robust regulatory structures. By connecting technological innovation with policy and ecological restoration objectives, the proposed framework supports resilient AMD control over the entire mine lifecycle and contributes to sustainable post-closure water management.
