Abstract

Currently, motor lubricants that are widely consumed are lubricants produced from the processing petroleum. The avaibility of petroleum as raw material for lubricants was decreasing. Therefore we need an alternative material can be further processed into alternative lubricants. This can be done by making biolubricant from processing vegetable oil derivatives. The purpose of this study was to determine the process of makin biolubricant from red palm stearin, to determine the effect of reaction time in the second stage of the transesterification reaction on the quality of biolubricant from red palm stearin and to produce bio lubricant with characteristics according to SNI No. 06-7069.5-2005. Research on the manufacture of this bio lubricant made from red palm stearin used a transesterification process. The fixed variable in the study were temperature 150°C, stirring in 400 rpm, mole ratio 1 : 3.9. and 1% sodium methoxide catalyst. And the variables of this study were the transesterifications time for making triesters TMP, namely 120,150,180,210, and 240. The analysis carried out was analysis of yield, density, viscosity, viscosity index, and corrosion rate. The results of this study showed that the length of time for step 2 transesterification had an effect on viscosity, viscosity index, corossoin rate, and yield.

Abstract

Indonesia is the largest palm oil producing country in the world. Every ton of processed oil palm fruit yields approximately 230 kg of empty fruit bunches (EFB). Currently, only about 10% of the EFB generated by the palm oil industry is utilized, while the rest remains as waste. This has prompted researchers to explore ways to optimize its use, one of which is converting EFB into activated charcoal.. The aim of this study is to examine the effect of phosphoric acid concentration on the quality of activated charcoal made from EFB. The research consists of two main processes: the carbonization of EFB and the activation of the resulting charcoal using phosphoric acid as an activating agent. The concentrations of phosphoric acid used for activation were 6M, 7M, 8M, 9M, and 10M.. Based on the results, the activated charcoal produced at all acid concentrations met the Indonesian National Standard (SNI 06-3730-06). The best quality activated charcoal was obtained using 10M phosphoric acid, with quality parameters including a moisture content of 7.76%, ash content of 6.55%, and an iodine adsorption capacity of 1,011.60 mg/g.

Abstract

This Community Service (PkM) activity aimed to enhance the knowledge of 10th-grade students at SMAN 1 Kuok, Kampar Regency, regarding the sustainable palm oil industry, palm oil processing, and the health benefits of its derivative products, especially red palm oil. The background of the activity was the students' lack of knowledge about palm oil and its derivatives, despite living in a palm oil plantation hub. The implementation methods included a location survey and needs analysis, knowledge and technology transfer, active partner participation, interactive counseling, and evaluation through pre-test and post-test. The results showed high enthusiasm from the participants. Questionnaire-based evaluation revealed that the activity was considered highly beneficial and successfully improved students' understanding of palm oil, its derivative products, and their health benefits. It was concluded that this PkM activity was effective in increasing students' knowledge and is expected to encourage their role as agents of change in supporting the sustainable palm oil industry in their region.

Abstract

Stunting merupakan masalah gizi serius yang masih tinggi di Indonesia, termasuk di Kabupaten Indragiri Hilir dengan prevalensi 18,8%, lebih tinggi dibandingkan target nasional 14% pada tahun 2024 (Kemenkes RI, 2021). Kondisi ini berdampak pada pertumbuhan fisik, perkembangan kognitif, dan produktivitas anak di masa depan (WHO, 2020). Salah satu intervensi gizi potensial adalah pemanfaatan minyak makan merah, produk olahan dari minyak sawit mentah yang kaya β-karoten sebagai provitamin A dan vitamin E, terbukti mengurangi risiko kekurangan vitamin A dan meningkatkan kadar retinol serum (Dong et al., 2017). Penelitian menunjukkan bahwa minyak makan merah dengan kandungan karoten ≥380 ppm efektif dalam mencegah stunting pada anak usia dini (Khairiah & Sihotang, 2024). Program pengabdian ini melibatkan Tim Penggerak Pemberdayaan Kesejahteraan Keluarga Kabupaten Indragiri Hilir sebagai mitra strategis yang memiliki peran penting dalam edukasi gizi keluarga. Program Pengabdian Kepada Masyarakat (PKM) ini bertujuan meningkatkan keterampilan kader dalam memproduksi minyak makan merah skala rumah tangga, memperluas pengetahuan masyarakat tentang gizi seimbang, serta membuka peluang usaha baru. Kegiatan meliputi sosialisasi, pelatihan, penerapan teknologi prototipe, serta pendampingan. Jumlah peserta mencapai 72 orang (kader TP PKK dan tenaga puskesmas). Uji mutu awal menunjukkan kadar karoten minyak makan merah sebesar 420 ppm, melebihi ambang minimal 380 ppm. Evaluasi kuisioner menunjukkan peningkatan pemahaman manfaat (+44%), peningkatan pengetahuan teknis (rata-rata 78%), mitra yang telah mencoba prototipe meningkat dari ±20% menjadi 68% (+48%), kemudahan penggunaan dari ±30% menjadi 76% (+46%), dan ketersediaan bahan baku meningkat (+22%). Hasil kegiatan menunjukkan peningkatan keterampilan kader dalam produksi minyak, kesadaran gizi masyarakat, serta munculnya peluang usaha baru berbasis minyak makan merah. Program ini mendukung pencapaian SDGs, Indikator Kinerja Utama Perguruan Tinggi, serta Perpres No. 72 Tahun 2021 tentang percepatan penurunan stunting Kegiatan ini membuktikan bahwa pemberdayaan masyarakat melalui inovasi berbasis komoditas lokal mampu memberikan dampak positif terhadap kesehatan, ekonomi, dan kesejahteraan keluarga

Abstract

Biodiesel production produces crude glycerol as a byproduct that cannot be utilized directly because it still contains various impurities. The crude glycerol used in this study had a glycerol content of 72%, a water content of 1.78%, ash content of 16.4%, and a density of 1.08 g/cm³, which indicates that the glycerol quality is still low due to the high water content and inorganic components. This study aims to evaluate the effectiveness of three types of adsorbents, namely activated carbon, zeolite, and bentonite, in improving the quality of crude glycerol from used cooking oil. The purification process is carried out through distillation, acidification, and adsorption stages with adsorbent variations of 5%, 7%, and 9%. Then, the purified glycerol was analyzed based on the parameters of glycerol content, water content, ash content, and density.

Abstract

The quality of crude palm oil (CPO) is an important factor affecting the success of the refinery process, particularly during bleaching. This study aimed to evaluate the effect of CPO quality with different Deterioration of Bleachability Index (DOBI) values on the quality of refined bleached deodorized palm oil (RBDPO) at various bleaching earth dosages. Two CPO samples with DOBI values of 2.67 and 0.87 were used, while bleaching earth concentrations were varied at 0.5%, 1.0%, 1.5%, 2.0%, and 2.5%. The observed parameters included carotene content, percentage of carotene reduction, absorbance value as an indicator of oil clarity, peroxide value, and percentage of peroxide value reduction. The results showed that increasing the bleaching earth dosage improved bleaching effectiveness, as indicated by decreases in carotene content, absorbance, and peroxide value in both CPO samples. CPO with a DOBI value of 2.67 exhibited greater reductions in carotene, absorbance, and peroxide value than CPO with a DOBI value of 0.87. These findings indicate that the initial quality of CPO significantly influences bleaching efficiency and the quality of refinery products.
