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

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

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%.

Abstract

Cooking oil has been used repeatedly, also known as used cooking oil. Used cooking oil or used oil is usually disposed of carelessly so that it becomes waste in the surrounding environment. This community service activity aims to educate the people of Bontang City about the dangers of using cooking oil. The participants of this activity are the people of Bontang City, especially high school / vocational / MA students. So that the results of community service, especially for students in Bontang City, can improve their abilities and bridge in educating the public about the dangers and utilization of used cooking oil waste. This activity consists of discussion, demonstration, and hands-on practice. The method in this community service is practice and demonstration to provide skills to participants in determining the right formula for making soap from used cooking oil. After this activity, it is hoped that high school/ vocational / MA students in Bontang City will be more aware of the dangers of using used cooking oil and can utilize used cooking oil waste in products that have useful value.
