Abstract

Empty Fruit Bunches (EFB) of oil palm are the main solid waste generated by the palm oil industry, with an increasing volume and high lignocellulosic content that can affect the decomposition process. This article aims to review the effectiveness of various microorganisms as bioactivators in EFB composting based on experimental studies and recent literature. The review results indicate that using microbial consortia such as Trichoderma spp., cellulolytic bacteria, and local microorganisms (MOL) is more effective than single microorganisms in reducing the C/N ratio to levels approaching the compost quality standard (<20). Aerobic composting methods with proper aeration management and the addition of organic materials can also accelerate decomposition. Further research is recommended to examine the interactions among microorganisms within the consortia and to conduct application trials to validate the agronomic benefits of EFB compost sustainably.

Abstract

The water-gas shift (WGS) reaction is a crucial process for increasing hydrogen (H₂) production by minimizing carbon monoxide (CO) content. It is widely applied in the petrochemical industry to reduce CO levels in syngas produced from hydrocarbon reforming. Conventionally, this reaction is conducted in two stages: high-temperature shift (HTS) and low-temperature shift (LTS). However, this approach presents both technical and economic limitations. To address these issues, catalysts capable of operating optimally at intermediate temperatures—referred to as medium-temperature shift (MTS)—have been developed. The scope of discussion in this article consists of catalyst development challenges such as sintering, deactivation, and side reactions. This review is intended to serve as a reference for the development of efficient WGS catalysts under MTS conditions, along with modification strategies aimed at enhancing their performance based on current research findings.

Abstract

The energy content of a fuel is represented by its calorific value. When biodiesel combusts in the presence of air or oxygen, the heat released during the combustion process is expressed as the calorific value. This study aims to analyze the effect of reaction time (60, 120, and 180 minutes) and the volume ratio of chicken fat oil-to-methanol (OM) (25:30 and 25:50) in the transesterification process on the calorific value of the produced biodiesel. The transesterification process was conducted using MgO as a catalyst under various reaction times and OM ratios. The produced biodiesel was then analyzed to determine its calorific value as a key fuel quality parameter. The results indicate that a longer reaction time and a higher OM volume ratio lead to an increase in the calorific value. The highest calorific value obtained in this study was 9952 kcal/kg, achieved at a reaction time of 180 minutes and an OM volume ratio of 25:50.

Abstract

Food spoilage, driven by factors like microbes and oxygen, is a major challenge in food preservation. Edible films offer an eco-friendly and biodegradable solution, acting as a protective barrier that reduces waste and extends a product's shelf life. While starch is a common and affordable material for these films, it has limitations, including poor water resistance and brittleness. This study investigates combining starch and pectin to create a superior composite edible film. This approach leverages the synergistic interaction between the two materials, which forms a more stable, dense structure through hydrogen bonds. This combination enhances key properties like tensile strength, flexibility, and water vapor resistance. The specific structure of the pectin, such as its level of methylation, is crucial, as it directly impacts how well it blends with starch and the film's final performance. By carefully controlling these interactions, the resulting edible films can achieve properties comparable to some fossil-based plastics, positioning them as a promising and sustainable alternative for food packaging. To support these findings, this research will analyze and review key performance factors from studies published over the past five years.
