Abstract

ABSTRAK Biodiesel merupakan bahan bakar ramah lingkungan yang dihasilkan melalui proses transesterifikasi antara minyaknabati dan alkohol dengan bantuan katalis.minyak kelapa sawit Adalah bahan baku utama yang potensial karenamemiliki ketersediaan yang melimpah. Pembahasan ini bertujuan untuk menganaisis aspek termodinamika dankinetika pada proses transesterifikasi minyak kelapa sawit menjadi biodiesel.berdasarkan Jurnal yang telah kami baca.Analisis ini difokuskan pada jenis katalis,suhu reaksi,jenis alcohol, dan nilai energi yang mempengaruhi produtivitasbiodiesel.Hasil telah menunjukan bahwa Sebagian besar analisis ini menggunakan model kinetika Arrhenius denganpendekatan kinetika orde satu terhadap trigliserida.niali yang terkandung dalam energi aktivasi (Eₐ) sekitar 10–60kJ/mol, dengan katalis basa homogen (NaOH dan KOH) menghasilkan laju reaksi lebih cepat dan Eₐ lebih rendahdibandingkan katalis heterogen berbasis CaO atau abu sawit.secara termodinamika dan reaksi transestrifikasi bersifatendotermik dan reversible, dikarenakan peningkatan suhu dan rasio alcohol mempercepat proses pembentukanbiodiesel.Metanol ini terbukti lebih efisien dibandingkan dengan etanol, karena metanol menghasilkn konversi tinggilebih tinggi dan waktu reaksi lebih singkat dibandingkan dengan etanol. Pemahaman yang luas terhadap hubunganantara termodinamika dan kinetika yang menjadi dasar penting utuk merancang proses produksi biodiesel yang lebihefisien, ekonomis dan berkelanjutan. ABSTRAK Biodiesel is an environmentally friendly fuel produced through a transesterification process between vegetable oiland alcohol with the aid of a catalyst. Palm oil is a potential primary raw material due to its widespread availability.This discussion aims to analyze the thermodynamic and kinetic aspects of the transesterification process of palm oilinto biodiesel based on twenty journals that we have read. This analysis focuses on the type of catalyst, reactiontemperature, type of alcohol, and energy value that affect biodiesel productivity. The results show that most of theseanalyses employ the Arrhenius kinetic model, using a first-order kinetic approach for triglycerides. The activationenergy (Eₐ) value is around 10–60 kJ/mol, with homogeneous base catalysts (NaOH and KOH) producing fasterreaction rates and lower Eₐ compared to CaO-based heterogeneous catalysts or palm ash. Thermodynamically, thetransesterification reaction is endothermic and reversible, as increased temperature and alcohol ratio accelerate thebiodiesel formation process. Methanol has proven to be more efficient than ethanol, as it produces higher conversionrates and shorter reaction times compared to ethanol. A broad understanding of the relationship betweenthermodynamics and kinetics is an important basis for designing a more economically efficient and sustainablebiodiesel production process.

Abstract

Minyak sawit dan turunannya merupakan sumber utama asam lemak jenuh dan tak jenuh, sehingga cocok sebagai bahan baku untuk menghasilkan senyawa bioaktif melalui modifikasi kimia. Salah satu perkembangan menarik adalah produksi bahan aktif antimikroba dari asam lemak sawit, khususnya dengan memproduksi monoasilgliserol (MAG), diasilgliserol (DAG), dan turunan oksidasi seperti epoksida asam lemak, peroksida, dan diol. Makalah ini membahas temuan penelitian selama dua puluh tahun terakhir tentang modifikasi kimia asam lemak sawit untuk menghasilkan bahan aktif antimikroba yang dapat digunakan dalam industri makanan dan farmasi. Penelitian ini dilakukan dengan menganalisis 20 jurnal ilmiah dari dalam dan luar negeri, yang mencakup proses gliserolisis, etanolisis, oksidasi terpilih, dan pengujian aktivitas antimikroba dari senyawa yang dihasilkan. Metode sintesis kimia dan enzimatik telah dilaporkan menghasilkan turunan MAG/DAG dan asam lemak teroksidasi dengan ketahanan oksidasi dan aktivitas antimikroba yang baik terhadap bakteri Gram positif dan Gram negatif. Berdasarkan hasil tinjauan, tampak bahwa monogliserida, terutama monolaurin dan monopalmitin, memiliki efek penghambatan yang kuat terhadap Staphylococcus aureus, Escherichia coli, dan Bacillus cereus, sementara senyawa epoksi dan peroksida dari asam oleat dan linoleat memiliki potensi antimikroba dan sifat antioksidan tambahan. Potensi ini membuka peluang besar untuk mengembangkan pengawet makanan alami dan bahan aktif farmasi yang berasal dari sumber minyak sawit yang ramah lingkungan.

Abstract

This study aimed to determine the optimal rotational speed of the thresher in improving the stripping efficiency of sterilized oil palm fruit bunches. The thresher functions as a rotating drum that separates loose fruits from the bunch by lifting, striking, and pushing empty bunches toward the empty bunch conveyor, while the loose fruits fall through the drum grid and are conveyed to the digester. The research was conducted using a quantitative descriptive method at PT Perkebunan Nusantara IV Regional II Dolok Ilir Palm Oil Mill, Dolok Batu Nanggar District, Simalungun Regency, North Sumatra Province. Data collection at the thresher station was carried out for 20 days, from May 5 to May 24, 2025, including measurements of thresher rotational speed, grid spacing, and loose fruit diameter. The results showed that the optimal thresher rotational speed ranged between 23.8 and 23.9 rpm, with an average grid spacing of 4.51 cm and an average loose fruit diameter of 2.67 cm. The standard deviation of measurements was 0.42%, indicating high operational stability. Technically, the correlation between thresher rotational speed and loose fruit diameter was 21.24 rpm, while the technical deviation correlation was 12.24%..

Abstract

Several factors that affect boiler efficiency in Palm Oil Mill are saturated pressure, feed water temperature, steam temperature, amount of steam produced, amount of fuel consumption, and calorific value of fuel combustion. The purpose of this study is to obtain the relationship between saturated pressure variations and boiler efficiency, the relationship between feed water temperature variations and boiler efficiency, the relationship between variations in the amount of steam produced and boiler efficiency, and to analyze the calorific value of 75% fiber fuel + 25% shell and Water Tube boiler efficiency. From the analysis results that have been carried out, it was obtained that the relationship between saturated pressure variations and boiler efficiency is not constant, but fluctuates. The relationship between feed water temperature variations and boiler efficiency shows an inconsistent pattern, while the relationship between variations in the amount of steam produced and boiler efficiency is relatively constant and increasing. The high combustion calorific value (HHV) is 21323.584 kJ/kg, and the low combustion calorific value (LHV) is 18083.584 kJ/kg. The highest boiler efficiency value produced is 68% and the lowest boiler efficiency value produced is 49%.

Abstract

Quality control of Crude Palm Oil (CPO) is essential to ensure compliance with quality standards. This study aims to control and analyze CPO quality parameters, namely Free Fatty Acid (FFA), moisture content, and dirt content, using the Seven Tools of Quality Control. The research was conducted at a palm oil mill in South Labuhanbatu Regency, North Sumatra, using laboratory quality data collected from October to December 2024. A descriptive quantitative method was applied by utilizing check sheets, Pareto diagrams, control charts, and fishbone diagrams within the Quality Control Circle (QCC) approach. The results showed that quality deviations occurred in 28 samples for FFA, 22 samples for dirt content, and 14 samples for moisture content. Pareto analysis indicated that FFA and dirt content were the main contributors to quality problems, accounting for 78.13% of total deviations. Control chart analysis revealed several periods of process instability, particularly in FFA values. The study concludes that the Seven Tools of Quality Control are effective in identifying dominant quality problems and supporting improvement efforts to enhance CPO quality.

Abstract

The timing of harvesting in oil palm plantations necessitates objective and rapid ripeness assessment, coupled with an estimation of extractable oil volume. This paper presents a philosophical-computational framework with an end-to-end architecture integrating Internet of Things (IoT) sensors and machine learning (ML) for the classification of fresh fruit bunch (FFB) ripeness levels and oil volume regression. The approach rests on explicit ontological and epistemological foundations, operationalizes latent targets through standardized field protocols, and implements reproducible ML practices. We delineate a multimodal pipeline (RGB imagery + environmental sensors + weight), a late fusion modeling strategy (CNN embeddings + tabular features), and an evaluation design that emphasizes cross-block generalization, model explainability, and drift monitoring. Performance targets include an F1-macro ≥ 0.88 for ripeness classification and a Mean Absolute Error (MAE) ≤ 4 ml/kg for oil volume regression on out-of-block data. Discussions also encompass the ethics and axiology of transparency, data governance, and economic impacts, along with future directions such as federated learning and portable hyperspectral integration.
