The study of starter concentration effect and fermentation period of cocoa pulp on ethanol production has been carried out in order to determine the concentration of Saccharomyces cereviceae as a starter and optimum fermentation period to produce bioethanol from cocoa pulp. Variables in this research were S. cereviceae consentration of 6, 7, 8 and 9%; and fermentation periods 3, 5 and 7 days. The results showed that 5 days of fermentation period and the addition of S. cereviseae with a concentration of 9% obtained the highest ethanol content as much as 5.93% by the end of fermentation acidity of 6.0.

Pasta is a kind of food made from wheat flour, water and other additional ingredients. This research was aimed to know the impact of wheat flour substitution with maize flour in pasta making. Preliminary research was done to found the better formulate between CMC, STPP, wheat flour and maize flour in pasta making and resulted good formula between wheat flour ad maize flour were 90% : 10%: 80%: 20%: and 70%: 30%. These formulate were used for the main research and the best formulated were resulted on 90% wheat flour and 10% maize flour water content was 9,10% which near to control value 8,14%. Rehydration potential was 9,93 minute and elasticity value 792,4 N/m2 which almost similar the elasticity control value 810,73N/m2.

The urgency of analyzing the needs of learning media is very important to analyze the needs of student learning media because there is a possibility that future learning will increase. For this reason, it is important to conduct further research on school policies in meeting student learning needs during the learning process. This study aims to analyze the needs of learning media in biology subjects at SMAN 4 Tanjungpinang. The research method used was descriptive and quantitative analysis with data collection through questionnaires and interviews with biology teachers. The subject of this study was a grade 11 science student of SMAN 4 Tanjungpinang. The results showed that teachers always use learning media in every meeting and with the existence of learning media makes students motivated and not easily bored in the learning process. However, students still need a variety of learning media to support learning needs. This article emphasizes the importance of effective learning through the use of appropriate media and materials.

This study aims to determine the physical and chemical characteristics of fermented and unfermented BR 25 clone dry cocoa beans. The treatment in this study was the fermented treatment (Treatment A) and the unfermented treatment (Treatment B). The fermented and unfermented treatments were processed from wet cocoa beans with 10 kilograms of beans for each treatment. The fermentation treatment uses a box of Styrofoam, while the unfermented treatment is directly dried in the sun after removing the mucus (pulp). The parameters for fermented and unfermented dry cocoa beans were water, pH, fat content, protein, polyphenols, antioxidant activity (IC50), and ALT. The results showed that fermented cocoa beans had a moisture content of 5.77%, pH of 6.41; fat content of 55.63%; protein of 14.36%; polyphenol content of 4.62%; antioxidant activity (IC50) of 21.96%; and ALT value of 1.0 x 102 colonies/gram. Unfermented cocoa beans have a moisture content of 6.52%, pH of 5.20; fat content of 59.63%; protein of 17.83%; polyphenol content of 2.06%; antioxidant activity (IC50) of 62.23%; and ALT value of 1.1 x 102 colonies/gram.Keywords: cacao beans; fermented; unfermented; characteristics

INOVASI PEMANFAATAN TANAMAN BAMBU MENJADI LAMPU HIAS Sjahruddin, Herman; Djaya, Subhan; Linan Langodai, Theresia Megawati; Hasmia, Hasmia; Rosniati, Rosniati; Saniapon, Nining

Utilization of bamboo plants as a form of innovation by increasing the utility of bamboo into lanterns. The abundance of bamboo resources is the reason for carrying out community service activities through training activities carried out for approximately one month in Sunggumanai Village, District. Pattallassang, Gowa Regency, South Sulawesi Province. The training is carried out as an effort to support the fulfillment of the economic needs of the community through the use of abundant natural resources in the village through the use of bamboo plants. The stages of the implementation of this activity began with observation activities and then continued with training on making bamboo lantern products. This product training activity was carried out at the Village Office in collaboration with village institutions (Bumdes) which was attended by village communities who in this activity acted as training participants. From the implementation of this activity, various benefits were obtained, namely an increase in people's income, changes in behavior, increased knowledge and skills, because the slowly made lanterns gain sympathy from consumers and in turn can increase people's income
