Penanganan limbah kelapa sawit terutama pelepah kelapa sawit menjadi perhatian khusus. Hal ini disebabkan karena minimnya optimalisasi limbah saat ini terutama pada Industri Kecil dan Menengah khususnya pada kelompok tani. Melimpahnya pelepah kelapa sawit yang berserakan di kebun diakibatkan belum diolahnya pelepah menjadi produk bernilai tinggi. Beberapa produk yang dapat dihasilkan dari limbah pelepah kelapa sawit adalah pupuk, pakan ternak, tali serat dan biopellet. Kendala yang dihadapi oleh mitra adalah tidak memiliki mesin pencacah pelepah kelapa sawit sebagai bahan baku pembuatan produk tersebut. Minimnya pengetahuan dalam merancang mesin pencacah pelepah kelapa sawit dan minimnya modal dalam pengadaan mesin tersebut menambah bagian permasalahan dari mitra usaha ini. Melalui Program Kemitraan Masyarakat ini tim menawarkan solusi untuk merancang dan menerapkan mesin pencacah pelepah kelapa sawit sebagai upaya pemecahan masalah tersebut. Tahapan pelaksanaan kegiatan yang direncanakan seperti: Analisis Situasi pada Unit Usaha, Merancang dan membuat mesin pencacah pelepah kelapa sawit, Melakukan pelatihan pengoperasian dan maintenance mesin sekaligus penyerahan mesin kepada Unit Usaha, Evaluasi Program Kegiatan. Diharapkan dengan Program Kemitraan Masyarakat ini dapat mereduksi limbah pelepah kelapa sawit, diversifikasi atau variansi produk dan meningkatkan pendapatan pelaku usaha dari unit Industri Kecil dan Menengah dalam hal ini kelompok tani.

Batik Jembatan Akar Small and Medium Industry (IKM) endeavors to produce Root Bridge batik fabric, which is a defining feature of the IV Nagari Bayang Utara sub-district. In its production process, IKM Batik Jembatan Akar still relies on rudimentary and traditional equipment and lacks the means to handle textile waste, leading to its disposal in nearby ditches. While the current waste output may not be significant, its continuation poses a threat to the local environment. Insufficient awareness of the environmental impact of textile waste can result in environmental pollution issues and disrupt community harmony around IKM Jembatan Akar. Additionally, IKM Batik Jembatan Akar struggles to stimulate consumer interest in traditional batik amidst the abundance of low-priced printed alternatives. The limited demand for production means that this SME has yet to invest in technology and waste processing equipment for its batik cloth production. Politeknik ATI Padang Community Service initiative seeks to educate all IKM Batik Jembatan Akar employees on the importance of waste processing and online marketing strategies, while providing training on donated textile waste processing equipment to enhance sales value and mitigate environmental harm. The approaches employed in this community service endeavor include (1) comprehensive activity planning, encompassing location surveys, production assessments, and inventory checks; (2) the fabrication and testing of waste processing machinery; (3) educational workshops covering waste management in batik production and its environmental implications, alongside practical training in equipment usage; (4) evaluation of activity outcomes. The outcomes of this Community Service initiative include the provision of textile waste processing equipment and a heightened awareness of environmental conservation, facilitating the integration of waste processing equipment into batik production at IKM Batik Jembatan Akar.

Several MSMEs in Padang Panjang City are engaged in livestock and processed meat and poultry products. These MSMEs can still be said to be small businesses because they implement a pre-order (PO) system for marketing, the variety of products offered is quite diverse, but limited knowledge about quality meat processing and market demands related to food products that comply with halal principles, and effective marketing strategies are not yet well understood as seen from the product packaging which still looks simple. The purpose of this community service activity is for MSMEs to be able to develop and improve product quality, increase competitiveness in the market, and contribute to local economic growth. The ATI Padang Polytechnic Team provided assistance including the introduction of meat processing techniques to create new product variations such as good and halal sausages, selection of quality raw materials, and the right marketing strategies to increase product competitiveness. The activity was carried out on August 20, 2024. The results of the Community Service activities were shown from the questionnaire given to participants. It is known that MSMEs in Padang Panjang city have been able to understand about natural and artificial food additives, healthy and halal meat processing processes, halal certification, shelf life of processed meat products and effective marketing methods.

SMA Yadika 5 has one of the goals, namely "Providing knowledge and skills in the field of entrepreneurship and plant cultivation that are beneficial for students and the surrounding environment". In cultivating plants, supporting materials such as organic fertilizer are needed. Coconut juice is often used as a cooking ingredient in household activities, where the pulp from coconut juice that is no longer used can generally be reprocessed into organic fertilizer. Organic fertilizer can improve the chemical, physical and biological fertility of the soil, in addition to being a source of nutrients for plants. Organic fertilizer made from coconut pulp waste for plants can be one way to carry out the goals of SMA Yadika 5. In addition, it can be a solution for agriculture or plantations for housewives or family members of SMA Yadika 5 students in urban areas. Based on the analysis of the situation around us, it turns out that teenagers are interested in learning this knowledge but have not had the opportunity because there has been no training and counseling in managing waste. The target of this training in managing household organic waste from coconut pulp is male and female teenagers at SMA Yadika 5, Kembangan District, West Jakarta.

This study aims to produce biodiesel from Refined Bleached Deodorized Palm Oil (RBDPO) using a heterogeneous catalyst based on calcium oxide (CaO) derived from limestone andmodified with palm oil mill fly ash (FA) as a catalyst support. The limestone feedstock was first activated to obtain the CaO catalyst. Subsequently, the FA material was activated through calcination at 500°C. The CaO-FA catalyst was synthesized using the wet impregnation method and then calcined at 600°C. This catalyst was applied in the transesterification of RBDPO with methanol at various molar ratios. The study investigated the effect of different CaO-FA catalyst compositions (1:1, 2:1, and 3:1), and methanol:RBDPO molar ratios (8:1, 10:1, and 12:1) on biodiesel yield. The results demonstrated that both the CaO-FA catalyst ratios and the methanol:RBDPO molar ratios significantly influenced the biodiesel yield and the resulting Fatty Acid Methyl Ester (FAME) composition. Gas Chromatography-Mass Spectrometry (GC-MS) analysis revealed that the 3:1 CaO-FA composition with an 8:1 methanol:RBDPO molar ratio produced biodiesel with the highest methyl palmitate (C17H34O2) content of 88.99%, which meets the characteristics of high-quality biodiesel. These findings provide valuable insights into the development of CaO-FA-based heterogeneous catalysts for cost-effective and environmentally friendly biodiesel production, in line with government initiatives to promote renewable energy utilization.

Palm Oil Mill Effluent (POME) contains a high organic load and requires effective treatment to prevent environmental pollution while enabling energy recovery. Anaerobic digestion is widely applied for POME treatment due to its ability to reduce organic pollutants and produce methane-rich biogas; however, its performance is highly dependent on process stability. This study aims to evaluate the stability of the anaerobic digestion process of POME through correlation analysis among volatile fatty acids (VFA), total alkalinity (TA), suspended solids (SS), and methane content (CH₄) using field operational data. The study was conducted at an industrial-scale biogas plant treating POME, where slurry samples were collected periodically from multiple biodigester units representing different digestion stages. VFA and TA were analyzed using acid–base titration, SS by gravimetric method, and methane content using a gas analyzer. The results show that the anaerobic digestion process operated under stable mesophilic conditions (35 ± 2 °C) with reactor pH maintained in the optimal range of 6.8–7.5. VFA concentrations remained relatively low (approximately 480–510 mg/L), supported by sufficient alkalinity (about 5,600 mg/L as CaCO₃), resulting in a low VFA/TA ratio (~0.09), indicating stable process conditions. A significant reduction in COD from approximately 41,700 ppm in the influent to about 7,200 ppm in the effluent was achieved, corresponding to a COD removal efficiency of 83%. Methane content in the biogas remained stable at ≥55%, supporting effective energy utilization without flaring. These results demonstrate that maintaining a balanced relationship among VFA, alkalinity, suspended solids, and operating conditions is essential for ensuring stable anaerobic digestion and consistent biogas quality in industrial-scale POME treatment systems.

Palm oil mill effluent (POME) is a high-strength agro-industrial wastewater whose management governs both environmental performance and operational resilience of palm oil mills. Treatment trains optimized solely for COD/BOD reduction often accumulate operational penalties under feed variability, including scaling, sludge burden, and persistent polishing demands, rather than forming a controllable value-generating platform. This review reframes nutrient recovery from POME as a fertilizer manufacturing problem embedded in a wastewater system, where removal does not equal recovery unless nutrients are transferred into a defined product phase with mass-balanced yield, controlled composition, impurity management, and agronomic function. Anaerobic digestion is positioned as a pivotal pivot point because it converts organic load to methane while producing an anaerobically digested liquor that is operationally more suitable for targeted nutrient recovery than raw POME. Using a PRISMA-ScR scoping review with a systematic search, evidence was mapped across three coupled outcome domains: water reuse/reclamation, energy recovery (biogas/CH₄), and nutrient circularity (N–P recovery and derived products). The synthesis compares unit operations by function and operability constraints, then assembles feasible combinations into a process superstructure and a decision roadmap for pathway selection under mill constraints. Findings emphasize that raw POME and anaerobically digested POME are not interchangeable feedstocks: raw POME is dominated by solids/colloids that hinder selective recovery and contaminate products, while post-digestion variability is more chemistry-driven and governs precipitation windows and membrane stability. Recovery options converge toward hybrid systems integrating crystallization (struvite/phosphate minerals), adsorption/ion exchange with regenerability, membrane concentration including fertilizer-drawn forward osmosis, and biological assimilation (microalgae), with fouling, scaling, and crystallization inhibition as decisive design variables. Overall, meaningful nutrient recovery from POME is achieved only when fertilizer grade products are produced while simultaneously reducing compliance risk and operational burden.
