Management information system (MIS) of Engineering Faculty (EF) Internship Office (IO) Universitas Negeri Semarang (UNNES) 2018 is an efficient and effective information system in colleges. The purpose of this study is the learning outcomes of MIS IO EF UNNES 2018 through users and systems. This research method was conducted using a questionnaire with HOT (Human, Organization, and Technology) fit model. This questionnaire was filled by 64 respondents consisting of students, supervisors, study program coordinator, administrative both departments and faculties. The results show that the user’s response to human instruments was a good average (54%) but the assessment of the department and faculty administration by all respondents was only 3% and 1.5%. Meanwhile, the average organizational instrument was good (53.86%), but the climate factor or organizational culture (55.40%) was the best from the organizational existence (55.01%) and the quality of organizational work (50.22%). Finally, it was good (54%) with the system quality factor (55.28%) was better than the information quality factor (53.15%). Improvements to the website consist of the front view and the contents of the system. This questionnaire can help the performance of MIS IO EF UNNES 2018.

The increase in plastic causes environmental problems. Indonesia ranks second with 5.4 million tons/year. Plastic waste cannot be degraded, so it is necessary to replace plastics with biopolymers as bioplastics. Starch-based bioplastics have high biodegradability, one of which is from durian seeds. Durian seeds have a fairly high starch content of 76.65%. Optimization of the mechanical properties of bioplastics in the form of extension needs to be done. This study aims to obtain the gelatinase temperature process conditions, glycerol and chitosan compositions that produce optimum bioplastic elongation. The optimization method uses a Response Surface Methodology based on Central Composite Design. The experiments were gelatinization temperature (80, 85, and 90°C), glycerol concentration (1.5; 2.5; and 3.5 g), and chitosan concentration (2, 3, and 4 g). The results of the study were the optimum conditions at a gelatinization temperature of 80°C, a concentration of 2 g of chitosan, and 3.5 g of glycerol with an elongation value of 26.67%. Biodegradation test for 7 days resulted in a mass reduction of 90.02% according to European standard EN: 13432.2000.
