Nutritional needs for humans in addition to staple food, the need for vitamins as additional food such as fruit. Consumption of fruits will produce fruit skin waste. Garbage is a problem for human life in the world. Unlike the case with organic waste, organic waste for Dr. Poompanvong can be converted into an eco-enzyme. Eco-enzyme is a multifunctional liquid produced from the fermentation of waste or organic waste, brown sugar / granulated sugar, and water. Eco-enzyme is a magic liquid whose benefits are very environmentally friendly, such as in the production process of eco-enzymes to produce O3 gas (the same as planting 10 trees), one liter of eco-enzyme solution can purify contaminated rivers, as an antiseptic and fertilize the soil. The objectives of implementing this community service activity are: first to introduce an organic waste management program with the concept of eco-enzymes; second, through dedication can produce output in the form of a national journal. This activity was held on July 28, 2020 at SMA Teruna Bhakti Waena Jayapura City and July 30, 2020 at SMA Negeri 2 Skanto Keerom. The target audience involved in this activity is high school students. The selection of target audiences is based on the duties and obligations of students to build Adiwiyata High School that loves the environment. The methods used in the implementation of the activity are lectures, simulations and practices on organic waste processing with the concept of eco-enzymes. The conclusion was that the participants were enthusiastic and knew the results of organic waste products with the concept of eco-enzymes. Based on the results of the evaluation, it shows that the level of participant satisfaction is high when viewed from the percentage of all aspects.

Thermophilic bacteria are bacteria that are able to survive in environmental conditions with high temperatures. Thermophilic bacteria are one of the important sources of thermostable enzymes that can be isolated from geothermal environments such as hot springs with temperatures ranging from 50–80 oC. Aims of the study to isolate and identify local isolates of thermophilic bacteria from hot springs in Moso Muara Tami District, Papua. The results showed that 7 isolates (A1, A2, A3, A4, B1, B2, and B3) that were isolated and identified based on phenotypic characters were included in the genus Bacillus. Key words: Thermophilic, characterization, isolation, identification, phenotypic.
Genetic substance of DNA has many functions as a basic component of the organism. DNA can be obtained directly through the isolation of DNA. Isolation of genomic DNA Wamena arabica coffee is done by treating the young leaves to get DNA extract. This reasearch is intended to provide scientific contributions in an effort to screen the best methods of DNA isolation, including a modified extraction of Zheng et al method (2005), a modified method of Doyle and Doyle (1990), and method of George and Khan modificaation (2008) or CTAB method. All of methods were tested on Arabica coffee Jayawijaya Wamena. Testing was done by looking at the difference in quality and quantity of products in the form of genomic DNA concentration and DNA thickness, comparing with the marker DNA then electrophoresis on agarose gel. From the results of testing the effectiveness of three types of isolation methods, it was found that the method of George and Khan (2008) or CTAB genomic DNA produce the best quality than other methods. In terms of quantity, the criteria in the form of DNA concentrations ranging from 100 ng λ-DNA/ml, λ-DNA 50 ng/ml, λ-DNA 10 ng/ml. Concentration of genomic DNA bands visible when the profile is visualized in gel electrophoresis with UV luminescence. This study will be a step and initial information about the genetic composition of a population of arabica coffee which still exists, and will be developed through DNA amplification technique. Key words: coffee, isolation of genomic DNA, CTAB method, profile band pattern
The aim of this study was to understand the plant species grown in house yard of local people in Heram District which had been used as food by local people and the potential of those plant to be and income sources for local people. This research was conducted from August 2016–April 2017 using survey and laboratory analysis. Purposive sampling was used to determine the sample, and from 5 villages 5 house yard will be selected to be the sample (total 25 house yard). From this study we found that there were 45 species from 33 family of plants which used as vegetables, ingridients, fruits, and mainly foods.Key words: tanaman pangan, masyarakat lokal, Papua
Recently, SMAN 4 Jayapura is the only one high school in Jayapura which implemented aaccelerate program for their student. The pupils included into this program should complete their studies within two years, which is one year earlier than common pupils. The problems rising from this program was with limited times (2 years) the student should accomplish all the same theory with regular class, which means they have to have extra class to finish it. Therefore, our team was ofering the solution to be an assistant for their extra class. The extra class was given after school hours, start from 3pm to 5pm once a week. The result of our assistance, the student can complete all the theory within times given and from total 28 students 10 of them have choosen biology and its apllied for their major in University.Keywords: : accelerate class; biology; assistant; SMAN 4 Jayapura school
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
