Publisher : GoAcademica Research & Publishing

This study aims to estimate the shelf life by applying the Arrhenius formula model to "galendo" which is vacuum packed and stored at various temperatures. Estimation of the shelf-life limit of galendos was carried out by measuring the peroxide number and sensory values of galendos which were deliberately kept open without being packed at room temperature (25 ○C). The sensory values used as the threshold for consumer rejection of the level of galendo's rancid odor were achieved on the 27th day of storage and the current peroxide count value was 42.2724 meq/kg. Galendo which was vacuum packed with aluminum foil and stored at various temperatures of 15 ○C, 25 ○C, and 35 ○C, then the shelf life was determined using the Arrhenius and Q10 models based on the parameters of the total peroxide number (TPN) and the total microbial content. Based on the experiment in this study, the estimation results of galendo's shelf life based on the total peroxide number (TPN) test parameter show that storage at 15 ○C has a shelf life of 83 days with a deterioration rate (k) of 0.0207, storage at 25 ○C shelf life 67 days with a deterioration rate (k) 0.0247, and storage at a temperature of 35 ○C for 58 days with a deterioration rate (k) 0.0286. The rate of quality degradation with a value of Q10 (15 oC - 25 oC) of 1.23 and a value of Q10 (25 oC - 35 oC) of 1.16. The higher the storage temperature, the higher the microorganism content.

Indonesia’s high dependence on soybean imports as a raw material for tempeh has brought various efforts to find a substitute of this raw material. One of the most potential substitute is lupin (Lupinusangustifolius). However, the mass adoption of these beans as raw material for tempe production is still low. In this study, we test effects of several ratios between soybeans and lupine, by using mix starters on the characteristics and quality of a substituted tempeh. The results indicated that the best treatment for the substituted tempeh was a2b6 treatment with a 1: 2 ratio of soybeans and lupin by using the starter produced by Indonesian Institute of Sciences (LIPI). Moreover, the substituted tempeh has a low water and fiber content as well as sensory acceptable.

Physics is one of the subjects that have a conditional concept for every level of the subject matter. Students are basically already had its own conception before studying physics. Conception of students may be same or different with concepts that are derived from the experts. Different conceptions can be said to be a misconception. Misconceptions can be identified by the diagnostic tests are multiple choice tests using a scale of Certainty of Response Index (CRI). This research aims to minimize the misconception of students on the concepts momentum and impulse with model of learning by using two stay two stray (TSTS) and computer-assisted simulations. This research method using quasi-experimental design with nonequivalent control group design involves two classes (experimental and comparison of each of the 37 students and 35 students) as a subject of research. Classroom interactive lecture using model comparison to compare the learning effectiveness in minimizing any misconception. The research results showed that: 1) profile of the popular high school students on the concepts momentum and impulse after learning of more than 20%, 2) learning model Uses two stay two stray (TSTS) and computer-assisted simulations can minimize the misconception by misconception results percentage of post-test up 21.3%, smaller than the comparison class with the grade percentage misconception results post-test of 40.2%, 3) Effectiveness of learning model-assisted computer simulation of TSTS is better than an interactive lecture model viewed from the value of the Normalized Gain such that both classes of 0.64 and 0.14.

This study aims to develop and examine students' conceptions of Work and Energy in relation to the Indonesian Capital City in East Kalimantan, using the Four-Tier Test of Work and Energy (FORTUNE) Open-Ended. The 4D methodology was followed, involving defining, designing, developing, and disseminating the research. The FORTUNE test, comprising 13 questions, was administered to 70 tenth-grade students (44 girls and 26 boys) aged 15 to 16. Rasch analysis was applied to categorize student responses into seven distinct categories: Sound Understanding (SU), Partial Positive (PP), Partial Neutral (P0), Partial Negative (PN), Misconception (MC), No Understanding (NU), and No Coding (NC). The results revealed that FORTUNE effectively diagnosed students' conceptions, with 61% of responses falling into the Misconception (MC) category, while only 3% were classified as Partial Positive (PP). Notably, students displayed misconceptions in questions of moderate difficulty, as indicated by Rasch analysis. In conclusion, this study successfully developed and implemented the FORTUNE Open-Ended test to assess students' conceptions of Work and Energy in the context of the Indonesian Capital City in East Kalimantan. The findings highlight the prevalence of misconceptions among students, particularly in questions of moderate difficulty. Addressing and rectifying these misconceptions require targeted instructional strategies to foster a deeper and more accurate understanding of the topic. Future research should explore the effectiveness of intervention programs aimed at enhancing students' conceptual understanding of Work and Energy.
