Abstract

A geophysical research has been conducted to determine the level of hazard vulnerability in West Halmahera by using microtremor data. Microtremor data are analyzed using the Horizontal to Vertical Spectral Ratio (HVSR) method and it is processed using Geopsy software to know hazard vulnerability level in the region . Data analysis and processing are used as sources of information in physics learning materials using an integrated learning model. Research objectives are to train the students to understand the materials in the fields of study and to enhance other discovery ideas.This research method uses the correlational method and the type of research is experimental research. The research design is an uniquecase research design and the instrument used is tests and questionnaires. The results of this research indicate that the microtremor data using integrated learning models of integrated types have effect on the students’ Mastery of materials in the implementation of physics learning. The effect of the integrated learning model of integrated type on the students’ Mastery of materials on the concepts of vibration and waves is 16% and it is in low category. Whereas, the students' responses to integrated learning model of integrated type are quite fun and it can help to improve their mastery of the material on the concepts of vibration and waves.

Abstract

This study aims to analyze the effect of substitution of black rice flour as much as 25%, 50% and 75% on the quality of cookies including the quality of shape, color, aroma, texture and taste. This research was carried out with pure experimental research using a completely randomized design method. The data used were primary data from 25 semi-trained panelists by filling in organoleptic questionnaires. The data were analyzed using ANAVA, a duncan test was performed if Fcount> Ftable. The results showed a significant effect on the quality of color and taste, and there was no significant effect on the quality of shape, aroma, and texture. The best results based on organoleptic tests were found in X_1 with a 25% substitution of black rice flour.
