Crude Palm kernel Oil (CPKO) adalah minyak nabati yang diperoleh dari mesokarp buah kelapa sawit. Proses pengolahan CPKO pada Kernel Crushing Plant (KCP) mengenai risiko keamanan dan kesehatan pekerja serta lingkungan menjadi perhatian utama di PT.ABC. Potensi bahaya pada kasus kecelakaan kerja dan insiden lingkungan penting untuk dilakukan identifikasi, evaluasi, dan pengendalian. Penelitian ini bertujuan untuk mengidentifikasi potensi bahaya dalam pengolahan CPKO di KCP pada PT. ABC dengan metode HIRARC untuk dapat mencegah dan meminimalisir tingkat kecelakaan kerja. Data primer didapatkan melalui observasi langsung dan wawancara dengan personel terkait. Analisis data dilakukan dengan mengelompokkan bahaya, memberikan penilaian risiko, dan menerapkan upaya langkah-langkah pengendalian. Hasil penelitian menunjukkan beberapa bahaya yang terjadi, seperti terjatuh, terpeleset, kebisingan tinggi, terjepit karena mengatasi masalah pada peralatan yang sedang beroperasi. Berdasarkan penilaian risiko, terdapat empat kategori tingkat risiko, yaitu risiko ekstrim, risiko sedang, risiko tinggi, dan risiko rendah. Upaya pengendalian risiko yang dilakukan adalah eliminasi, substitusi, rekayasa teknik, administrasi dan alat pelindung diri. Metode HIRARC dapat membantu mengurangi tingkat risiko terhadap kesehatan dan keselamatan dilingkungan kerja.

Spent bleaching earth (SBE), a waste generated from palm oil bleaching, contains residual oil and organic matter that block its pore structure and pose environmental disposal concerns. Regeneration of SBE is therefore essential to enable its reutilization. In this study, SBE was regenerated by calcination and further modified via KOH impregnation at concentrations of 1.00, 0.10, and 0.01 M. The regenerated materials were characterized using XRF, SEM, TEM, XRD, and BET surface area analysis. Calcination combined with 0.10 M KOH impregnation increased the surface area from 8.70 to 93.81 m2/g, approaching the value of activated bleaching earth (94.29 m2/g), and significantly altered pore volume and pore size distribution. These findings indicate that calcination restores the basic structure of SBE, while subsequent KOH impregnation enhances its morphological properties, highlighting the potential of regenerated SBE as a low-cost adsorbent or catalyst support.

PT. XYZ is a palm oil processing enterprise. The products produced are crude palm oil (CPO) and palm kernel oil (PKO). The level of oil loss in PT. XYZ Empty Bunch Press should not exceed 0.90%, but there has been a significant increase in the last three months, exceeding the company's guidelines. This disease may have an impact on CPO production output. As a result, this study was done to investigate oil loss in empty bunch presses. The method employed is Statistical Process Control (SPC), which employs three tools: a checksheet, histogram for data distribution, and fishbone diagram to aid in understanding and fixing the problems encountered. The largest oil loss is 1.56%, which surpasses the Company's requirement of 0.9%. In order to achieve the required standards, suggestions for improvement must be made using a fishbone diagram that incorporates human, machine, method, and raw material aspects.

Smallholder oil palm plantations play a crucial role in the Indonesian palm oil industry, but research on their spatial characteristics and performance at the district level is limited, as most previous studies tend to generalize plantation trends without utilizing local geospatial analysis. This study addresses this gap by using QGIS 3.32.1 to classify, map, and assess the status of smallholder oil palm plantations in Tanah Laut Regency, South Kalimantan. Plantations are categorized into productive and non-productive based on district-level BPS data, with a total planted area of 14,479 ha, consisting of 12,693 ha of productive land and 1,786 ha of non-productive land. Batu Ampar has the largest productive land (3,527 ha), while Tambang Ulang and Panyipatan have significant non-productive land, 328 ha and 300 ha, respectively, indicating the presence of immature plantations. Total production varied between 396–4,603 tons, with Batu Ampar, Jorong, and Tambang Ulang as the main contributors, while yield per hectare ranged from 435–620 kg, with Bati-Bati recording the highest yield. These findings confirm that plantation management practices determine productivity more than land area alone. This study presents an integrative method that combines spatial and statistical data, facilitates district-level plantation monitoring, and demonstrates that the use of open-source GIS tools such as QGIS offers a cost-effective, replicable approach that supports planning, policy, and sustainable development for smallholder farmers.

Tofu is an Indonesian traditional food which basically made from soybean. Tofu production process yields both solid and liquid wastes. If these are not handled properly, they may cause environmental contamination. Therefore, clean production planning needs to be conducted in order to bringout an environmental friendly industry for increasing productivity, increasing efficiency of raw materials and reducing wastes. This research was conducted at the tofu processing industry UD. Sumber Urip by collecting data through field observation, interview, questionnaire filling and 3 (three) stages of quick scan method which consists of identifing the production process of tofu based on the concept of clean production through the mass balance, analysing the alternative clean production improvements, observating and giving recommendations on waste utilization. The result shows that the tofu production process with clean production through the mass balance produced 210 kg dregs of tofu and 2.115,51 kg total liquid wastes. The research also proposes some alternative improvements of clean production as the implementation of good housekeeping principle, modification of funnel principle grinding, utilization of personal protective equipment, and implementation of recovery and reduce principle. On the other hand the wastes generated from the tofu production process may be reproduced in to tempe gembus, animal feed, organic fertilizer, and biogas.
