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

Gas rumah kaca (GRK) dalam bentuk CH4 dan N2O memberikan kontribusi terhadap pemanasan global. Sektor pertanian menyumbang 10-12% dari total GRK antropogenik dari gas CH4 dan N2O. Sedangkan sektor peternakan menyumbang sekitar 18-51% GRK antropogenik. Penelitian bertujuan untuk menganalisis beban emisi gas CH4 dan N2O bersumber dari Peternakan terhadap GRK Di Kabupaten Muara Jambi yang diestimasi dengan menggunakan metode Tier-1 IPCC. Pada metode ini data yang diperlukan adalah populasi ternak dalam satu tahun 2018 dan nilai faktor emisi (FE) setiap gas GRK menurut buku panduan IPCC (2006). Data populasi ternak sapi diambil dari buku statistic peternakan, sedangkan nilai FE diambil dari buku IPCC (2006). Hasil penelitian menunjukkan beban emisi gas CH4 dari fermentasi enterik 1,1227 Gg CH4/tahun, Emisi CH4 dari Pengelolaan kotoran 0,0239 Gg CH4/tahun, emisi N2O langsung dari pengelolaan kotoran 465,85 Kg N2O/tahun dan emisi N2O tidak langsung dari pengelolaan kotoran ternak 69,88 Kg N2O/tahun. Sektor peternakan telah berkontribusi terhadap pemanasan global yang bersumber dari gas CH4 dan NO2 baik dari fermentasi enterik maupun dari pengolaan kotoran ternak sapi.

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.
