AbstractÂ Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Patchouli oil is an essential oil obtained from the leaves of patchouli (Pogostemon cablin) by distillation. Oil is a non-oil export commodities among the most volatile oil exports in Indonesia. Patchouli oil exports in 2004 amounted to 1295 tons, while exports of the whole essential oil was 2633 tons (BPS, 2006). So that nearly 50% of volatile oil exports, dominated by patchouli oil. Patchouli oil are not only used as perfuming ingredients, can also be used as a drag scent perfumes other perfuming ingredients that do not quickly lose aroma and more durable (fixative) in the manufacture of perfumes, cosmetics and soap. Even today, the patchouli oil many developed toward drug product. This is because the essential oil contains more than 24 types of sesquiterpene, which has the potential as anti-cancer compounds, anti-microbial, anti-inflamatory, antibiotics and anti-microbial and anti-tumor. One component of patchouli oil potential and have a very high sale value of patchouli alcohol. Almost all the components of patchouli alcohol can produce the flavor and health products and medicines, and some researchers have attempted to separate them. Therefore, it is necessary to separate the essential oil of patchouli alcohol by combining the extraction and distillation in one column using a solvent used frying oil. This process is known as extractive distillation. Used frying oil is a solvent that can bind impuritas and alter the relative volatility of components in the original condition. This research started with the design and manufacture vacuum extractive distillation.

Minyak nabati merupakan komoditi perkebunan yang memiliki kegunaan, baik sebagai bahan baku oleokimia maupun oleopangan seperti asam lemak. Pemenuhan kebutuhan Asam lemak untuk industri di Indonesia selama ini masih dilakukan dengan import. Mengingat bahwa asam lemak dapat dibuat dari biji karet, dimana di Indonesia hasilnya sangat melimpah sehingga perlu diupayakan untuk dapat memproduksi sendiri dalam upaya penghematan devisa negara. Selama ini produksi asam lemak dilakukan dengan mengolah lanjut minyak nabati, padahal untuk memproduksi minyak nabati sendiri sudah memerlukan biaya operasi maupun investasi yang cukup tinggi. Oleh karena biji karet mengandung enzim lipase yang dapat menghidrolisa trigliserida yang ada dalam biji karet menjadi asam lemak dan gliserol maka perlu dikaji teknologi proses produksinya. Penelitian ini bertujuan mencari kondisi operasi optimum untuk menghasilkan asam lemak secara langsung dari biji karet. Kajian dilakukan dengan cara percobaan untuk mendapatkan kondisi operasi proses dan cara aktivasi enzim lipase yang ada dalam biji karet.

[Bioconversion of Organic Waste using Balck Soldier Fly (BSF): In Collaboration with Resik Sejahtera Waste Community in Polaman Village, Semarang] In many developing countries, such as Indonesia, waste management remains a major issue. The community generates a large amount of waste, however the method for processing organic waste is still landfilling waste in the Final Processing Site (TPA). The amount of organic waste reached 65.05% in 2010, according to the Assessment and Application of Technology. As a result, organic waste processing solutions are required. The larva of the Black Soldier Fly, known as the maggot, is beneficial to humans and does not spread disease. Maggot is a type of animal feed that is regularly used. Maggots contain 43.42% protein, 17.24% fat, 18.82% crude fiber, 8.70% ash, and 10.79% water, making them a viable protein substitute. Furthermore, maggots are better at degrading organic waste than other insects. Maggot growing is the best way to deal with the community's organic waste problem. Community service activities have increased community members' and the Polaman Village community's knowledge and skills in organic waste processing using maggot media, which can reduce animal feed costs, vegetable compost costs, and increase community members' and the Polaman Village community's income.

The pollution resulting from domestic waste has increased with the growing population density, and one of the potential contributors to groundwater contamination is detergent waste. Sodium Lauryl Sulphate (SLS) serves as a common active ingredient in detergent formulations. By leveraging membrane technology, SLS can be processed to reduce its concentration in water to environmentally safe levels. Chitosan, a promising material for membrane composition, is considered as the base material. Exploiting the hydrophilic characteristics of chitosan, silica is introduced to enhance membrane selectivity by reducing pore size through cross-linking between chitosan and silica molecules. The performance of the silica-modified membrane is then evaluated through tests measuring the rejection coefficient against SLS, membrane swelling degree, morphological profiling of functional groups using FTIR, and tensile strength measured with a Universal Testing Machine. Subsequently, the membrane's efficiency in rejecting SLS in detergent waste is assessed based on rejection coefficients using an SLS solution model.
