The effort of developed hand sanitisers (HS) production is needed in the era of the Covid-19 pandemic. The improvement of HS in terms of colour, aroma sharpness, and hand comfort is very important in the consideration of users choosing the HS product used. The socialisation of this service aims to report community service in creating HS production on a scale of 6 L/30 minutes using Propeller Mixing Hand Sanitizer (PMHS) by testing color, aroma, and hand comfort using synthetic and natural materials with chemical technology processes. The addition of the aroma of natural ingredients from fruit, flowers or seeds using maceration techniques from strawberry fruit, jasmine flowers, green tea leaves, and coffee grounds were extracted by the natural aroma liquid, which were added to HS products. The addition of HS products with the aroma of natural ingredients from strawberry, jasmine, green tea, and coffee was compared to the synthetic aromas of strawberry, jasmine, green tea, and coffee obtained from perfume shops. The questionnaire test of 44 respondents consisting of lecturers, staff, administration, and students for HS products evaluated color, aroma sharpness, and hand comfort. The results show that the colour, sharpness of the aroma and a sense of comfort in the hands of HS products with synthetic aromas of jasmine and green tea are highly favoured by users. These results were recommended as a reference for the manufacture and distribution of HS aromas of jasmine and green tea on a large scale.REFERENCESKualitas Gel Pembersih Tangan (Handsanitizer) Dari Ekstrak Batang Pisang Dengan Penambahan Alkohol, Triklosan Dan Gliserin Yang Berbeda Dosisnya.” Bioeksperimen 4(2):61–70.Anugrah Ricky Wijaya, Yudhi Utomo, Sumari, and Irma Kartika Kusumaningrum. “Pembuatan Hand Sanitizer Menggunakan PMHS (Propeller Mixing Hand Sanitizer).”HKI: 2019Diah JuliantariD, Ni Putu, Luh Putu Wrasiati, and Ni Made Wartini. 2018. “karakteristik ekstrak ampas kopi bubuk robusta (coffea canephora) pada perlakuan konsentrasi pelarut etanol dan suhu maserasi.” Jurnal rekayasa dan manajemen agroindustri 6(3):243. doi: 10.24843/JRMA.2018.v06.i03.p08.Golin, Andrew P., Dexter Choi, and Aziz Ghahary. 2020. “Hand Sanitisers: A Review of Ingredients, Mechanisms of Action, Modes of Delivery, and Efficacy against Coronaviruses.” American Journal of Infection Control 48(9):1062–67. doi: 10.1016/j.ajic.2020.06.182.Nazma Sabrina Sani, Rofiah Racchmawati dan Mahfud. 2012. “Pengambilan Minyak Atsiri Dari Melati Dengan Metode Enfleurasi Dan Ekstraksi Pelarut Menguap.” Jurnal Teknik Pomits 1(1):1–4.Riza Ibnu Fajar, Luh Putu Wrasiati*, Lutfi Suhendra. 2018. “kandungan senyawa flavonoid dan aktivitas antioksidan ekstrak teh hijau pada perlakuan suhu awal dan lama penyeduhan.” Jurnal Rekayasa Dan Manajemen Agroindustri 6(3):196–202.Septiani Mangiwa, Agnes Eri Maryuni. 2020. “Pengaruh Metode Ekstraksi Terhadap Sifat Fisik Dan Kimia Ekstrak Biji Kopi Sangrai Jenis Arabika (Arabica Coffea) Asal Wamena Dan Lanny Jaya.” AVOGADRO Jurnal Kimia 4(1):31–40.Shabri dan Dadan Rohdiana. 2016. “Optimasi Dan Karakterisasi Ekstrak Polifenol Teh Hijau Dari Berbagai Pelarut.” Jurnal Penelitian Teh Dan Kina 19(1):57–66.Sulusi Prabawati, Endang D.

Jamur tiram putih (Pleurotus ostreatus) merupakan bahan pangan yang sangat digemari masyarakat. Selenium adalah salah satu mikronutrien essensial yang masih rendah pemenuhannya. Penelitian ini bertujuan untuk menganalisa beberapa faktorr yang berpengaruh dalam fortifikasi selenium pada jamur tiram putih. Jamur tiram putih merupakan tanaman saprofit yang menyerap bahan makanan dari media tanam untuk pertumbuhannya, karena itu masa pertumbuhan dan kandungan badan buahnya dipengaruhi oleh komposisi dan keasaman (pH) media tanam. Makalah ini akan memaparkan tentang pengaruh keasaman (pH) dan waktu panen terhadap kandungan selenium badan buah jamur tiram. Dari hasil penelitian diperoleh kesimpulan bahwa, pertumbuhan miselium jamur paling cepat terjadi pada jamur tiram yang ditanam pada media tanam pH 8. Kadar selenium pada badan buah jamur dipengaruhi oleh lama pertumbuhan miselium jamurnya, jamur yang ditanam pada media dengan pH 6 memiliki kadar selenium yang paling tinggi, serta terdapat perbedaan yang signifikan antara kadar selenium badan buah jamur yang dikumpulkan dari waktu panen pertama dan waktu panen kedua. White oyster mushroom (Pleurotus ostreatus) is a very popular food. Selenium is one of the essential micronutrients for human. The intake of selenium is low. The aim of this research is to analyze some factors that affect to selenium fortification on white oyster mushrooms. White oyster mushrooms are saprophytic plants that absorb their food from their growing media, so the growth periode and their fruit body content is influenced by the composition and the acidity (pH) of their growing media. This paper describes about the effect of acidity (pH) and the harvesting time on the selenium content of oyster mushroom. From the results, we concluded that the most rapid growth of mycelium occurred on the oyster mushroom that grown on growing media with pH 8. The selenium content of mushroom fruit body are influenced by their mycelia growing period, the oyster mushroom that grown on growing media with pH 6 had the highest selenium content ,and there is significant difference between the content of selenium of the mushroom fruit body that collected from the first and second harvesting time.

The competition in petroleum industry to meet customer requirements is very tight. Companies that are able to survive are a company that can meet consumer demand in a timely manner. Companies must pay attention to the smoothness of its distribution system so as to meet consumer demand for continuous and timely. The problems frequently encountered by the Petroleum Industry are a delay in delivery of fuel from depots to filling stations are located in the region such coverage Depot. This is caused by a number of previously unknown oil demands, the limited number of tank cars for fuel and lack of accuracy, adequacy determination of delivery routes fuel from depots to retail outlets. This paper is intended to help the Oil Industry to determine the fuel distribution system and the determination of delivery routes with the aim of minimizing shipping costs and delivery schedules to determine fuel from depots to retail outlets. The method used in this study is the Distribution Requirements Planning (DRP) to determine how the delivery of fuel from depots to retail outlets each with respect to the amount of the daily requirement of each pump.This research begins with forecasting demand for fuel at 81 gas stations for several future periods. Under the DRP method of forecasting at each gas station for one week ahead will be a need for fuel to be supplied by the Depot Tasikmalaya. So that the Depot can estimate the amount of fuel that must be sent to each retail outlets in the coming period. Furthermore Djikstra algorithm used to determine fuel delivery routes from depots to retail outlets. The selected route is a route with a shorter distance and minimum shipping costs. After that car assignment scheduling done by using rule-based scheduling longest travel time (Longest Processing Time), to obtain the finish time of fuel delivery is almost the same on every car is assigned.Use of the DRP method, assignment and scheduling and Djikstra algorithm, tank car is useful because it can estimate the needs of Tasikmalaya Depot gas station in the coming period so that the fuel supply depot in accordance with the requirements both in terms of quantity and time, can determine the route of delivery of fuel depots to gas stations with the shipping costs more low-cost, timely delivery time and workload tank car that is almost the same.

Black garlic is a traditional spice having potential of herbal medicine; however, continuous heating darkens its color and changes its taste due to chemical processes and new equilibrium in the system. In this study, fresh garlic was processed into black garlic at 60 °C for 24 days. Changes in physical and chemical parameters, such as browning and protein content, reducing sugar content, and antioxidative components were recorded. Protein content was measured by Kjeldahl method, brown color development was analyzed using a color reader, reducing sugar was examined using a dinitro salicylic DNS reagent, and antioxidative activities were studied with a diphenyl picrylhydrazyl DPPH reagent in terms of their percent inhibition. Gas chromatography – mass sepctrometry (GC–MS) and Liquid Chromatography-High Relosultion Mass Spectrometry (LC–HRMS) were performed to determine the chemical profiles. Results showed a number of interesting features. The protein and sugar contents increased up to 3 and 4 times that of the initial values, respectively during processing. The antioxidative properties improved in the later stages. The chemical profiles of volatile and nonvolatile components were altered in their final stage. Sulfur and nitrogen-containing nonvolatile components were relatively stable during heating, but their compositions changed. The natural chemical changes reflect the biological potential dynamics in biological processes as herbal supplements. The reflection of the processes might go further into food chemistry and the food industry. This needs an interdisciplinary approach, expanded to biological concepts and safe, ethical industrial processes.

Free Fatty Acids (FFA), which include unsaturated fatty acids like oleic and linoleic acid and saturated fatty acids like palmitic and stearic, are present in most oil compositions. The various negative impacts of FFA require these compounds to be eliminated. This research aims to separate FFA using Liquid-Liquid Extraction (LLE) and determine the levels of FFA using acid-alkalimetric titration in corn oil and palm oil. FFA extraction was carried out for 4 minutes with a solvent ratio of 9,5 ml diethyl ether + 40 ml ethanol + 0,5 ml water. By adding 1M Na2SO4, re-extraction was carried out for 3 minutes. The results obtained were 0.95% FFA levels in corn oil and 1.26% FFA levels in palm oil. FFA levels of both oils are still below the SNI FFA percentage of 3%; besides that, it is found that the FFA levels in palm oil are higher than in corn oil
