Abstract

Abstract: Research and development of the BPBL’s teaching materials (Blended-Problem Base Learning) aim to measure its effectiveness on students learning outcomes (in extraction and chromatography courses) and their soft skills. Based on the preliminary questionnaire regarding the need for the development of the BPBL’s teaching materials states that the students felt quite difficult to understand the concepts in extraction and chromatography so their learning outcomes does not meet the standards.  Students also realize that improving their soft skills is important for personal development, social participation, and success in the work environment. BPBL’s teaching materials are a combination between blended learning and problem-based learning. Using coffee as daily content is used to give meaningful learning for students and aim them to easily understand the concept in extraction and chromatography courses.  The effectiveness of BPBL’s teaching materials on learning outcomes of students with n-gain is 0,64 or 64% and the effectiveness on soft skill of students with n-gain is 0,31% or 31%, both are included in the medium effectiveness category. Abstrak: Penelitian dan pengembangan bahan ajar berbasis BPBL (Blended- Problem Base Learning) bertujuan untuk mengukur efektifitasnya terhadap hasil belajar (pada materi ekstraksi dan kromatografi) dan soft skill mahasiswa.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

An attempt to have a scientific course for the public from higher education institutions was done by preparing a good set of contents for one particular topic of interest, which is also a science topic. Coffee chemistry is the topic chosen and some content was developed, including videos, audio-embedded social media, infographics and motion graphics packed with 8 topics. The choice of coffee amongst many sciences’ topic is considered strategic in bringing science to all audiences of society. Science content must explain nature as the object in wholistic concepts, starting from smaller parts of each division, including chemistry. The microlearning approach is employed in the MOOC platform from The State University of Malang, Indonesia. This also is one of the three main tasks of higher education institutions which can be delivered in the MOOC system.
