Abstract

Green coffee beans to be stored for transportation must meet storage quality standards, especially the maximum moisture content of 12.5%, so the drying process must be carried out to achieve quality standards, but still economical. The study aims to obtain optimum operating conditions on the drying of Arabica-type coffee beans using a fluidized bed dryer assisted by zeolite adsorbents in a separated fluidized bed prior to heating, as well as calculating the energy consumption of blowers and air heater. The operating conditions were varied, namely air flow rate of 1.79 – 2.29 m/s, air temperature of 45 o C, 50 o C, and 55 o C, zeolite adsorbent mass of 150 g, 175 g, and 200 g. The coffee beans quality tests carried out were the moisture, carbohydrates, protein content, and the visual appearance of the beans. The results show that the optimum drying process of coffee beans resulting a minimum protein and carbohydrate damage are the air velocity of 2.1 m/s, air temperature of 55°C, drying time of 240 minutes, and zeolite adsorbent mass of 150 grams, with energy consumption of 5.02 KWH (equivalent to 180 MJ/T). The addition of zeolite as much as 150 grams, 175 grams, and 200 grams as adsorbent was able to reduce the relative humidity (RH) of air by 16.65%, 18.60%, and 21.17% respectively. The drying rate of coffee beans is mainly influenced by air temperature (more predominantly) than the adsorption of air humidity by zeolite.

Abstract

This research is entitled The Role of Group Counseling Using Sociodrama Techniques in Overcoming Prosocial Behavior in Adolescents in Subdistrict 8 Ilir Palembang. The aim of this research is to determine the description of prosocial behavior of adolescents before being given sociodrama techniques and to determine the role of group counseling using sociodrama techniques in dealing with prosocial behavior of adolescents. The research method used is field research. Data collection techniques include observation, interviews and documentation. Data analysis techniques consist of data reduction, data presentation and drawing conclusions. The results of the research are first, teenagers in sub-district 8 Ilir had low prosocial behavior before being given sociodrama techniques. This was proven by the results of the pre-action interview where it was seen that teenagers from sub-district 8 Ilir Palembang had low prosocial behavior, where in each indicator in the interview items, teenagers from sub-district 8 Ilir answered questions quite indifferently. Second, group counseling using sociodrama techniques has a significant role in overcoming prosocial behavior of teenagers in the 8 Ilir sub-district. This behavior increased significantly along with the meeting when the behavior was given. This is in line with the enthusiasm of the teenagers at every service delivery meeting, as well as the answers to every discussion regarding what should be done in the climax of the drama script. Apart from that, the interview answers to each indicator of prosocial behavior also gave a positive response, which could also be the answer that group counseling using sociodrama techniques has a significant role in overcoming adolescent prosocial behavior.

Abstract

This thesis research departs from problems seen in the field, where currently many educators still use conventional media. The background of this thesis is that the only media used by teachers in the eyes of Jurisprudence is the blackboard in the school. Even though at the school there are infocus facilities that can be used as learning media, teachers also do not utilize technology-based media. This has an impact on students' interest in learning and the quality of learning. Therefore, the researcher wants to develop an animated video on the Islamic Jurisprudence subject, using the Powtoon application at MTsN 15 Tanah Datar. The aim of this research is to determine the validity and practicality of the product being developed, namely animated videos on the Islamic Jurisprudence subject, the material on Mavaris. This research uses a type of field research, with the ADDIE (Analysis, Design, Development, Implement and Evaluation) development model method. The research procedure begins with the needs analysis stage of product development, the design or product planning stage, the product development stage, the implementation or product testing stage and the evaluation stage. Data collection tools include validation sheets and questionnaires. The product trial subjects are located at MTsN 15 Tanah Datar. Data analysis techniques for validation and response questionnaires use the Aiken Formula. Based on the results of the validity test of animated videos using the Powtoon application in Class IX at MTsN 15 Tanah Datar, the validation results on the media aspect in general are 0.94 with the criteria "very valid" and the validation results on the material aspects in general are 0.91 with the criteria "very valid" so the developed animated video can be used. The research continues to the implementation stage. The animated video was tested on eighteen class IX students for practicality testing. The practicality test on the media display aspect in general received a score of 0.85 with the criteria "very practical" and the material presentation aspect in general received a score of 0.85 with the criteria "very practical". Conclusion: Animated video media using the Powtoon application in Fiqh subjects at MTsN 15 Tanah Datar is suitable for use in Fiqh subjects
