Abstract

Corona virus disease (Covid-19) is a disease caused by a virus that attacks the respiratory tract and still continues today. The death toll from Covid-19 continues to rise in Indonesia as the number of positive cases of the coronavirus reaches thousands of people. One of the bacterial infections that cause respiratory infections is Klebsiella pneumoniae. One of the preventive efforts to prevent the spread of infections caused by the corona virus and bacteria is the renewal of waterless hand sanitizers called antiseptic hand sanitizers or hand sanitizers. The approach method used is to provide understanding to the students about the potential of waste treatment in the city of Bontang. Continue by socializing the manufacture of chitosan from shrimp shells and the process of processing chitosan to produce hand sanitizers. From the results of this training, it can be concluded with enthusiasm from the students that the activities are carried out well and are able to increase students' knowledge about the potential of waste in the surrounding environment and it is hoped that they will be able to practice making hand santizers on a simple scale. Keywords: Chitosan, Hand Santizer, Alcohol-Free, Islamic Boarding School Students.

Abstract

Tongkol jagung telah banyak digunakan sebagai sumber arang aktif atau karbon aktif dengan berbagai cara sintesis karena mengandung selulosa, hemiselulosa, dan lignin dengan kadar yang besar. Arang aktif merupakan senyawa karbon yang daya absorpsinya ditingkatkan melalui proses karbonasi dan aktivasi. Penelitian ini bertujuan untuk mengetahui pengaruh waktu aktivasi terhadap karakterisasi arang aktif tongkol jagung meliputi bulk density, Bagian yang tersisa pada pemanasan 950 oC, dan uji daya serap arang aktif terhadap larutan Iod (I2). Pada penelitian ini digunakan variasi waktu aktivasi 6, 12, 18, 24, dan 36 jam dengan menggunakan H2SO4 sebagai aktivator. Hasil penelitian menunjukkan seiring bertambahnya waktu aktivasi, bulk density semakin berkurang, Bagian tersisa pada pemanasan 950 oC semakin bertambah, dan daya serap terhadap larutan Iod (I2) semakin bertambah, di mana waktu aktivasi yang optimum adalah 36 jam. Data karakterisasi arang aktif tongkol jagung sudah memenuhi SII 0258-88, kecuali pada pengujian daya serap terhadap larutan iod (I2). Kata kunci: tongkol jagung, arang aktif, karakterisasi

Abstract

Papaya plants have considerable potential and have not been widely developed, especially in the seeds because there is a high enough oil and protein content. The objective of this study was to investigate in situ transesterification process which allows direct production of biodiesel from papaya seeds. Changing conditions of the process variables studied were the volume of the methanol (100, 200, 300 mL) and time of process (15,30,45, 60, and 90 minutes) with a specified variables weight and water content of seed, catalyst, stirring speed, temperature and observable effect of the yield of oil extracted to form FAME. Volume of methanol and reaction time significantly affect the yield FAME. The highest FAME yield obtained on the volume of 300 mL methanol and 90 minutes time reaction (77,68%).

Abstract

Banana production in Bontang City has increased every year. Along with the high productivity of bananas, the amount of banana peel waste will also increase. In general, waste in the form of banana peels is only used as animal feed or disposed of without further processing so that it can cause environmental pollution. For this reason, it is necessary to manage banana peels so that they have a higher economic value. Banana peel contains alkaloids, flavonoids, phenols, tannins and saponins. This Saponin will produce foam so that it can be used as a washing agent and can also be used as a kitchen equipment cleaner. The samples in this activity were ripe banana peels and orange peels as additives (fragrances and essential oil producers). The method used in the Activities for the Community is the presentation of the material. Discussion, and practice of making dish soap. Participants were very enthusiastic in participating in a series of training activities for making dish soap. The result of this training is an environmentally friendly dish soap product according to the method provided.

Abstract

Desalination (removal of salt content) of salt or brackish water into fresh water is another way to obtain fresh water. The two most widely practiced methods are distillation (distillation), heating seawater until it evaporates and then condensing to get fresh water and reverse osmosis, seawater at high pressure through a thin membrane to pass water molecules. Another method that can be used in the desalination process is the adsrobtion process. One of the media that can be used in the adsrobtion process is chitosan. This research is carried out by the bacth method with two variables, the first variable concentration, namely 800, 1600, 2400, 3200 and 4000 ppm. The second variable is the stirring time with variations, namely 100, 200, 300, 400 and 500 rpm. Based on the results of studies that have been carried out, the best concentration of shrimp skin chitosan is at a concentration of 4000 mg / L or the addition of 200 mg of chitosan in 0.25 L of brackish water. At this concentration, the absorbent can reduce the salinity of brackish water by 86.6694% and for the best stirring speed the shrimp shell chitosan is at a speed of 300 rpm with the addition of 1000 mg of chitosan in 0.25 L of brackish water. At this stirring speed, the adsorbent can reduce the salinity of brackish water by 82.6335%.
