Lapangan LV memiliki tiga sumur yang dapat dianalisis yaitu XD-02, XD-04, dan XD-05. Penelitian ini dilakukan untuk mengevaluasi formasi dan menentukan zona hidrokarbon untuk selanjutnya dilakukan perhitungan saturasi air. Penelitian dilakukan dengan menganalisis log secara kualitatif dan kuantitatif dengan menggunakan software Interactive Petrophysics. Analisis log secara kualitatif bertujuan untuk menentukan lithology formasi serta menentukan zona hidrokarbon, sedangkan analisis log secara kuantitatif bertujuan untuk melakukan perhitungan volume shale, porositas, resistivitas air formasi, dan saturasi air. Perhitungan saturasi air pada penelitian ini akan menggunakan metode simandoux. Metode simandoux biasa digunakan untuk formasi yang mempunyai kandungan shale sebesar 5-30%. Harga kandungan shale pada sumur XD-02, XD-04, dan XD-05 secara berturut-turut yaitu sebesar 15,38 %, 7,14 %, 14,29 %. Harga saturasi air dengan menggunakan metode Simandoux pada sumur XD-02, XD-04, dan XD-05 secara berturut-turut yaitu sebesar 19,90 %, 19,25 %, dan 12,32 %. Kemudian setelah didapat harga saturasi air, maka dapat dicari harga saturasi hidrokarbon yang terkandung didalam lapisan tersebut. Harga saturasi hidrokarbon pada sumur XD-02, XD-04, dan XD-05 secara berturut-turut yaitu sebesar 80,10 %, 80,25 %, dan 87,68 %. Dari hasil perhitungan ini disimpulkan bahwa sumur di lapangan LV cocok menggunakan metode simandoux untuk perhitungan saturasi air dikarenakan kandungan shale pada sumur-sumur tersebut masuk ke dalam kisaran 5-30%.

Used cooking oil is an oil that has been used repeatedly in the process of frying food. Repeated use of cooking oil will cause a decrease in the quality of used cooking oil and if consumed will be harmful to health. The decrease in the quality of used cooking oil due to the formation of more double bonds in the structure of used cooking oil causes the oil to be more easily oxidized. The oxidation experienced by used cooking oil causes the quality of used cooking oil to decrease marked by the increasing value of peroxide number, free fatty acid content, water content and acid number of used cooking oil. One of the efforts that can be done to improve the quality of used cooking oil is to add an adsorbent to the used cooking oil. The added adsorbent serves to adsorb the impurities contained in the used cooking oil. One of the adsorbents that can be used is zeolite, zeolite can be used as an adsorbent because of the wide surface area of zeolite which makes it easier for zeolite to adsorb chemical compounds on its surface. To test the quality of the oil can be done by measuring the peroxide number, free fatty acid content, water content and acid number. In this community service, training activities for refining used cooking oil will be carried out to the people of the Tanjung Gedong area, Tomang, West Jakarta. The link between PkM training in refining used cooking oil using natural zeolite for residents of the Tanjung Gedong area, West Jakarta and PkM flagship usakti, namely in the areas of regional development, ecogreen, and alternative energy. Namely using natural materials such as zeolite which is environmentally friendly to improve the quality of used cooking oil.

Indonesia has a large amount of liquid waste originating from the tofu industry. Currently, the treatment of tofu industrial wastewater is carried out using both anaerobic and aerobic methods, but both methods still have several weaknesses. In this study, the tofu industrial wastewater was utilized as a culture medium for Spirulina sp. to provide economic value from wastewater that can be used as bioethanol, pharmaceuticals, and food products rich in omega 3, chlorophyll, carotenoids. Aim: The growth of Spirulina sp. is closely related to the availability of macro and micronutrients as nutrients and the influence of environmental conditions, so this study was aimed to see the best variation of the addition of urea and NaHCO3 as additional nutrients to maximize growth and cell density of Spirulina sp. with tofu industrial wastewater media. Methodology and Results: This study was done by culvitating Spirulina sp in the growth media, measuring the Optical Density (OD), and analyzing quantitatively and using ANOVA on IBM SPSS Statistics version 20. The study indicated that adding urea and NaHCO3 to Spirulina sp. had no effect on cell density and growth rate. Treatment with addition of urea 0.36 g/500 ml without additional of NaHCO3 had the highest growth rate, 0.00852/day, and the highest cell density value on Spirulina sp. growth. Conclusion, significance, and impact study: The tofu liquid waste can be used as a new alternative used as fertilizer because in the liquid tofu waste, it provides the nutrients needed by Spirulina sp.

Drilling mud is a type of fluid that can help smoothing a drilling. The function of the drilling mud in the drilling process is to lift the drilling cutting. In this laboratory research, corn starch was used as a substitute for starch to reduce filtration loss. Corn starch is made by cleaning, drying, grinding, and sieving. The purpose of this research is to make mud with the addition of corn starch. its effect on filtration loss and mud cake at two temperature conditions. In this study the use of corn starch to be mixed into the mud with concentrations of 3 grams, 5 grams, 7 grams, 9 grams, and 11 grams. Accordingly, it can be seen which mud composition complies with the standard drilling mud specifications. Laboratory test results showed that the addition of corn starch additives caused a decrease in filtration loss for each difference in concentration and temperature. With the addition of 11 grams of corn starch, filtration loss decreased from 6.2 ml to 4.4 ml at 80°F, and it decreased from 5.2 ml to 3.9 ml at 200°F. In addition, corn starch additives cause the thickness of the mud cake formed to decrease. At a temperature of 80 oF the thickness of the mud cake decreased from 0.76 mm to 0.46 mm, while at a temperature of 200 oF it decreased from 0.62 to 0.42 mm. Based on the research results, corn starch additives and temperature influence changes in filtration loss and mud cake.

Metal plating frequently employs nickel (Ni) and copper (Cu) as anodes. Cu/ Cu-Ni film formed has many advantages, such as better corrosion resistance and high hardness characteristics. This study aims to assess the properties of Cu/Cu-Ni film, such as phase, surface morphology, crystallographic orientation, hardness, corrosion analysis, and contact angle, which were fabricated using electrodeposition with various Ni salt additions (0.3, 0.5 and 0.7 M). In addition, the cathode current efficiency (CCE) and deposition rate of the Cu/Cu-Ni electrodeposition were also investigated. An increase in Ni salt in the plating bath could enhance the pH, promoting higher CCE and depleting hydrogen evolution at the cathode, leading to the presenting Ni phase in the alloy. The higher concentration of Ni salt in the solution could also enhance the deposition rate due to a shift to a pH value, which affects the roughening of the surface morphology, promoting a higher contact angle. All crystal structures generated by Cu/Cu-Ni electrodeposition were FCC, with the preferred orientation of the (111) plane. Crystallite size and lattice strain depend on the deposition rate. Less crystallite size and lattice strain affect the film’s hardness and corrosion resistance. Moreover, the third bath had the resulting Cu-Ni layer with the best hardness and corrosion rate of around 136 HV and 0.081 mmpy.

Industri tahu adalah industri yang didominasi oleh usaha-usaha skala kecil dengan modal yang terbatas dan tersebar di seluruh wilayah Indonesia. Salah satunya adalah industri tahu Harapan Maju (HS) di Cimanggis, Depok, Jawa Barat. Industri ini masih menggunakan cara tradisional dengan membuang limbah ke sungai. Jika langsung dibuang ke sungai, limbah tahu dapat mencemari lingkungan. Oleh karena itu sebelum limbah dibuang, sebaiknya dijernihkan terlebih dahulu untuk menjaga lingkungan. Salah satu metode penjernihan adalah dengan menggunakan bentonit dan karbon aktif ampas tebu. Bentonit memiliki kemampuan untuk menyerap zat organik yang baik dan mengikat padatan yang relatif kecil dalam air. Sedangkan karbon aktif ampas tebu berfungsi sebagai penjernih dan menyerap logam berat pada air limbah. Proses yang terjadi adalah proses adsorpsi atau proses pemisahan zat padat dari fluida dengan jalan melewatkan fluida melalui medium penyaring atau septum sehingga zat padat akan tertinggal pada medium. Teknologi sederhana ini sangat efektif bila diaplikasikan dalam pengolahan air limbah industri tahu. Sebelum pengujian nilai BOD 714 mg/L, TDS 1129 mg/L, COD 1152 mg/L dan pH air limbah adalah 4. Pengujian dengan menggunakan kombinasi ampas tebu dan bentonit pada sampel 2c yaitu ampas tebu 1 gr dan bentonit 0.1 gr memberikan hasil yang terbaik, dimana nilai BOD 142,8 mg/L, TDS 407 mg/L, COD 195,84 mg/L dan pH 6 yang memenuhi standar Permen LH no.51 tahun 1995.

The world of oil cannot be separated from drilling operations in extracting hydrocarbons from below the earth's surface. Drilling mud or drilling fluid is essential to the drilling process. Cibinong Oil and Gas Vocational School is a vocational school that has two study programs, namely, Oil and Gas Drilling Engineering and Oil and Gas Production Engineering. The laboratory assistants at the Oil and Gas Vocational School have limitations in explaining in detail about drilling fluids. Therefore, activity is necessary to increase insight and knowledge of drilling fluids, especially in supporting practical activities. The method used in this activity is the dissemination of knowledge about drilling mud accompanied by the practice of making a simple drilling mud mixture. Making drilling mud is carried out by comparing KCl polymer mud and polyamine as a shale inhibitor. This comparison is seen from the results of the physical properties of the mud produced, namely mud weight, funnel viscosity, plastic viscosity, yield point, 10-second gel strength, 10-minute gel strength, filtration rate, mud cake, and pH (acidity level). With this introductory activity, knowledge about drilling fluids for laboratory assistants and chemistry teachers as participants in PkM activities has increased. This increase in knowledge can benefit students who will continue their education at the undergraduate level in earth sciences at universities.
