“…Nilai yang tinggi akan menghasilkan sedikit perubahan bentuk benda walaupun diberi gaya. Oleh karena itu, penambahan PVOH yang semakin banyak menghasilkan biofoam yang semakin kaku dan memiliki regangan elastis yang kecil karena nilai Modulus Young yang dihasilkan semakin besar [12].…”

Starch and fiber-based biofoam as a solution to replace the role of styrofoam. However, the biofoam still unqualified as a good foam characteristic. Polyvinyl alcohol (PVOH) is added to improve the physical characteristics of biofoam. This study aims to determine the effect of PVOH addition on the quality of starch-based biofoam from jackfruit seeds and corn hominy. The gelatinization process was carried out using a mixer in 350 rpm speed at 100 °C for 5 minutes, then moulded in a thermopressing unit for 25 minutes at 100 °C. The characteristics of the material with amylose and amylopectin contents 17.30% and 31.60% respectively and corn hominy's fiber content at 2.72%. The best PVOH addition was 10% addition based on its characteristics from parameters such as water absorption, density, and biodegradability were close to Synbra Technology’s standard. However, all the physical and mechanical characteristics of the produced biofoam still can't reach the standard.

This study is a quantitative study that aims to see whether there is an effect on the problem solving abilities of students who are taught by a project-based learning model with photonovelas media on global warming materials. this study used in this study was a multiple choice test to measure students’ problem solving abilities. The population taken in this study was seventh grade students of SMP Negeri Bongomeme. The sample used was 50 students, namely, 26 students in the experimental class and 24 students in the control class. The analysis used in this study uses Rasch modeling SPSS 16.0 applications, namely hypothesis testing with the Wilcoxon test. Introduction
