Abstract

This research aims to raise public awareness of the importance of utilizing household waste to make compost in Alue Sungai Pinang Village, Sub-District Jeumpa, Southwest Aceh Regency. By making compost, the household waste can be used as fertilizer and help create a clean environment from waste (zero waste). The method used in this research consists of 3 stages, namely: observation, preparation and implementation of activities. Compost is produced using materials originating from the household waste of Alue Sungai Pinang Village residents in the form of vegetable remains, rotting fruits, sawdust, and manure. Household waste that previously had no economic value can be processed or reused to become compost. This compost fertilizer can be applied to residents' plantations or to grow plants around the house such as vegetables, fruits and decorative plants.

Abstract

Even though phytoremediation is considered a green technology for remediating heavy metals, there are some problems with the application of this technology, particularly when it comes to managing the biomass that is used. So, processing biomass needs to be given a lot of attention. This study outlined the utilization of extracts obtained from the hyperaccumulator plant Brassica oleracea var. alboglabra to synthesize nickel oxide nanoparticles. Subsequently, the nanoparticle underwent testing to determine its suitability as an absorbent for heavy metals, specifically lead, as well as its efficacy as an antifungal agent against Fusarium sp. strain. The characterization of nickel oxide nanoparticles involved several measurements, such as scanning electron microscopy analysis, high- and low-resolution transmission electron microscopy, energy dispersive spectroscopy, X-ray diffraction, and hysteresis curve acquisition. The research findings indicate that the extract from hyperaccumulators can be utilized for the synthesis of NiO, which exhibits an absorption capacity exceeding 98% and serves as an efficient antifungal agent against Fusarium sp. pathogens. The approach utilized in this study not only prioritizes "green" and sustainability factors but also takes into account the economic aspects associated with the items being manufactured. The research has important implications in two areas. Firstly, it demonstrates the utilization of natural resources (B. oleracea var. alboglabra) in the production of nickel oxide, which serves as a safer and more eco-friendly substitute for dangerous chemicals. Furthermore, it aids in the advancement of novel techniques for effectively managing biomass hyperaccumulators.

Abstract

Kacang hijau (Vigna radiata L.) merupakan jenis kacang-kacangan yang paling banyak dikonsumsi oleh masyarakat Indonesia. Produksi kacang hijau yang dicapai petani masih terbilang rendah. Salah satu faktor yang menyebabkan rendahnya hasil produksi kacang hijau adalah serangan penyakit. Serangan penyakit pada biji kacang hijau dapat disebabkan oleh bakteri, virus dan cendawan. Sebagian besar biji kacang hijau disimpan dalam karung yang terikat dan disimpan didalam gudang, maka kondisi suhu yang tidak sesuai akan menyebabkan cendawan tumbuh dan melekat pada biji kacang hijau. Metode yang digunakan pada penelitian ini adalah metode blotter test. Metode blotter test adalah salah satu metode isolasi yang mengkondisikan agar cendawan dapat tumbuh pada kertas saring (blotter). Keuntungan dari metode blotter test yaitu cara pengerjaannya yang praktis dan dapat mengidentifikasi cendawan terbawa benih. Hasil yang didapatkan pada hari ke-7 yaitu cendawan Fusarium sp. dan Rhizoctonia solani.

Abstract

This study outlines the fundamental role of microorganisms including bacteria, archaea, and fungi as primary drivers of global biogeochemical cycles. Data were collected through a comprehensive literature review of various scientific databases, covering recent publications on the contribution of microorganisms to biogeochemical cycles. It explores how microorganisms facilitate the transformation of essential elements such as carbon, nitrogen, phosphorus, and sulfur through various metabolic pathways, ranging from atmospheric gas fixation to the decomposition of complex organic matter. It also highlights environmental factors that influence microbial activity, as well as the ecological and environmental implications of their roles, including contributions to climate regulation, soil fertility, environmental purification, and the impact of anthropogenic activities. A comprehensive understanding of microbial ecology is crucial for predicting and managing environmental systems amid global challenges such as climate change and pollution.
