Abstract

Community service activities have been carried out at SDN Inpres Dobonsolo, Jayapura Regency, Papua Province. This activity was in the form of counseling and demonstrations about the introduction of chemistry through Fun Chemistry for students. The purpose of this service is to increase and train creativity and foster students' interest in chemistry. Activities carried out by introducing the role of chemistry in everyday life and conducting simple experiments such as rainbows in bottles; blowing gas balloons using mentos and baking soda; elephant toothpaste; and color magic. Experiments were carried out using tools and materials that are easily available around at home or school. Students are very enthusiastic, active, interactive, and not rigid in conducting simple experiments at the demonstration stage. In other words, through Fun Chemistry students can develop skills in science and scientific attitudes, so that the assumption about learning chemistry is difficultKeywords: SDN Inpres Dobonsolo; Chemistry; Fun Chemistry; Simple Experiment

Abstract

Community service activities have been carried out at SMA PGRI Jayapura, Heram District, Jayapura City, Papua Province. The purpose of this service is to increase students' interest in chemistry through scientific papers training with simple research methods. The initial stage carried out in this activity is the socialization of scientific papers. The next stage is conducting simple research, processing data and training in writing scientific papers. The research topic chosen is the determination of water hardness by complexometry. During this activity the students were very enthusiastic and motivated. This can be seen when students listen to material explanations, discuss, conduct research and write reports. Based on the evaluation results, the success rate of this activity reached 80%. This is because there are still some students who have difficulty in processing data and writing reports. Therefore, the role of the teacher is very important in assisting students to increase interest and creativity in producing a scientific work.Keywords: training; scientific work; SMA PGRI Jayapura

Abstract

Several important chemical components are still present in coffee skin, although they have not yet been put to much use. This study aims to determine the physical and chemical quality as well as the antioxidant activities of cascara tea, which is produced from the skin of Papuan arabica coffee. Coffee skins are gathered by The Highland Roastery Café from several Papuan coffee producers. Cascara is used to make tea, which is packaged in tea bags after being sun-dried. The analysis of physical and chemical quality is in accordance with SNI 3753: 2014. Physical and chemical quality parameters for tea include the condition of the steeping water, moisture content, ash content, crude fiber, phytochemicals, polyphenols, and caffeine levels. It is possible to measure antioxidant activity using the DPPH technique. The physical and chemical characteristics of cascara tea manufactured from Papuan arabica coffee skins are as follows: typical brewing water conditions, moisture content, total ash content, and crude fiber are all 13.00 ± 0.11%, 10.96 ± 0.12%, and 40.55 ± 0.14%, respectively. Phytochemical screening showed that cascara tea contains alkaloids, terpenoids, saponins, and polyphenols, with a total polyphenol content of 1.33 ± 0.05% and caffeine of 0.44 ± 0.05%. Cascara Papua tea exhibits strong levels of antioxidant activity with an IC50 of 13.96 ppm. Therefore, it can be concluded that cascara tea, which is made from arabica coffee skins from Papua and sun-dried, has a physical and chemical quality that complies with the standards. and can be used as an antioxidant beverage to increase endurance. Key words: cascara; coffee skin; arabica coffee; physical and chemical quality; antioxidant.

Abstract

Smoked fish products produced by fishing households in Jayapura City are widely known, becoming food products that are popular with city residents and souvenirs for tourists. The development of this superior commodity requires at least four requirements, namely that commodity procurement must be continuous in quantity, quality and at the right time, have good traceability, continuous development and mastery of technology, and adequate mastery of business management. It is within this framework that this community service activity is carried out. The aim of this Community Partnership Service activity is to empower the community to increase their knowledge and skills in using appropriate fish smoking equipment, making hygienic packaging, understanding production and marketing management and making simple cash books in running a smoked fish processing business in Hamadi Village, Jayapura City. This service uses participatory rural appraisal methods, fisheries education, and pretest posttest control group design. Based on the results of the implementation of activities with POKLAHSAR Mama Papua partners on 26-27 August and 22-23 September 2023, it is known that there is an understanding of cash bookkeeping, the use of appropriate smoking equipment, production management and marketing management, as well as making hygienic packaging for smoked tuna. , has increased. It is hoped that this can become a benchmark for the development of the smoked fish business among partners as targeted in the activity objectives.
