Patchouli oil refinery in Gayo Lues Aceh Indonesia commonly used evaporation process in an old drums at high temperature which decreased the quality of oil produced. The research to enhance the quality of patchouli alcohol of Gayo Lues patchouli oil using Citrus hystrix absorber has been done.The juice from kaffir lime (1 – 10 % v/v) used as chelating agent, and the kaffir peels powder (2,5 - 7 gr) used as bio sorbent. The highest patchouli alcohol (P.A) both resulted at T=50 oC and 60 minutes heating. Kaffir bio sorbent at 7,5 gr usage, gave 40,37% P.A and Fe reduction of 77,67%; while kaffir lime juice at 4% v/v usage, gave P.A 39,90% and Fe reduction of 78,25%. Purified patchouli oil also characterized by its light yellow color, density and refractive index based on SNI.06-2385-2006. It’s concluded that kaffir peels bio sorbent purification has superior P.A quality than kaffir lime juice.

Adsorpsi merupakan suatu proses penyerapan, salah satu faktor yang mempengaruhi daya adsorpsi adalah luas permukaan (surface area). Pada penelitian ini digunakan adsorben biomassa berupa batubara sub-bituminous, untuk memperbesar luas permukaan dilakukan proses aktivasi. Aktivasi merupakan bagian dalam proses pembuatan adsorben biomassa yang bertujuan untuk memperbesar distribusi dan ukuran Pori serta memperbesar luas permukaan adsorben. Semakin luas permukaan adsorben, maka semakin banyak adsorbat yang dapat diserap, sehingga proses adsorpsi dapat semakin efektif. Semakin kecil ukuran diameter partikel maka semakin luas permukaan adsorben. Aktivasi fisika dan kimia dilakukan untuk melihat terbentuknya pori-pori baru pada karbon aktif yang telah di aktivasi, dengan terbentuknya pori-pori baru maka luas permukaan karbon aktif dapat meningkat setelah dilakukan proses aktivasi fisika kimia. Ukuran partikel hasil karakterisasi menggunakan difraksi sinar-X menunjukkan hasil yang jelas dimana ukuran partikel setelah di aktivasi menurun, aktivasi asam sitrat memberikan nilai sebesar 3,3396 (Å) dan aktivasi asam nitrat sebesar 3,3188 (Å) sedangkan karbon aktif batubara sub- bituminous sebelum di aktivasi sebesar 4,2269 (Å).Kata kunci: Biomassa, Batubara Sub-bituminous, Aktivasi, Asam nitrat, Asam Sitrat

The industrial wastewater load pollutant caused without treatment. This study uses a simple technology to reduce the levels of COD, BOD5, and Nitrite by using coffee husk to minimized waters pollution or environmental damage. Adsorbents are activated by HCl 0.1 N and carbonized with muffle furnance to enlarge the surface area of the sorbent and to absorb the contaminants in the effluent of tofu industry. Tofu wastes containing COD, BOD5 and Nitrite contacted with activated carbon with varying weight of 0.2, 0.3, 0.4 gr and different stirring times 10, 20, 30, 40, 50, 60 minutes and 125 rpm stirring speed with biosorbent size 80-100 mesh. The stirring time 10-30 minutes with the average concentration absorbed for BOD5 180 mg/l, COD 650 mg/l and NO2- 20 mg/l and increasing the mass of biosorbent can increase the concentrasion of adsorption. The efficiency absorption of wastewater absorbs more BOD5 than COD and Nitrite with BOD5 absorption efficiency is 85.38%. Adsorption of BOD5, COD and Nitrite follows Langmuir’s isotherm equation with R2 value is 0,8104 for BOD5, 0,7121 for COD and 0,7467 for nitrite

Rubber seed is a source of vegetable oil that can be used for biodiesel production, but its use is not optimal. Although rubber seeds contain a lot of oil, it is possible to process them into biodiesel and become a renewable energy source from vegetable oil. The aim of this research is to determine the maximum yield and the effect of temperature on the transesterification process. The results of the research show that temperature variations affect the properties of the obtained biodiesel, namely the maximum yield at a temperature of 60 ºC is 90%, the density value in accordance with SNI 7182:2015 at a temperature of 80 ºC is 853.5 kg/m3, the viscosity value in accordance with SNI 7182:2015 at a temperature of 60 ºC and 70 ºC with a value of 2.83 mm2/cSt and 2.19 mm2/cSt respectively. The GC-MS analysis was carried out on the best samples with density values according to SNI 7182:2015, namely samples with a temperature of 80ºC for 60 minutes and consisting of methyl ether linoleic acid with a surface area of 35.32% and oleic acid methyl ester with a surface area of 4.46%

Demand for salt in Indonesia continues to increase, while local production has not kept up and therefore relies on imports. Salt production faces challenges such as weather dependency and the risk of soil mixtures that degrade product quality. This community empowerment program aims to improve the quality and quantity of hygienic salt production in business groups through the application of geomembrane technology, and increase production capacity to meet standards. The program methods include socialization, technical training on geomembrane installation, assistance in production, and evaluation. The results and impacts of the salt production process increased by 20%, salt products produced are whiter, hygienic, and meet SNI standards. In addition, the income of the business group increased by 50%. This production has successfully improved productin efficiency and the welfare of salt farmers. In the future, the group plans to expand the market, improve infrastructure, and submit products for formal certification. Geomemran technology has proven to be an effective and sustainable solution in supporting hygienic salt production.

This study reports the synthesis and characterization of a monolithic activated carbon adsorbent modified with alumina and chitosan (Al-Chit/OAC), derived from oil palm empty fruit bunches (OPEFB). The adsorbent was fabricated through pyrolysis, followed by alumina incorporation and chitosan impregnation. FTIR analysis confirmed the presence of functional groups including OH stretching (3640cm), CH stretching (2920cm), CN/CO stretching (10551031cm), and AlO vibrations (693, 522, 495cm), indicating successful surface modification. TGA revealed two major stages of thermal degradation, with a total mass loss of 17.4% and a final residue of 17.55%, reflecting the presence of thermally stable inorganic components. SEM imaging showed a heterogeneous and porous surface with agglomerated particles and interparticle voids, suggesting enhanced surface accessibility. Even though we didn't test how well it absorbs substances, the physical and chemical properties of the composite show it could be very useful for cleaning up acid mine drainage (AMD) in the future. Further studies are recommended to validate its adsorption performance.
