Abstract

This research aims to determine the effectiveness of Teaching Model Type Assisted Individualization Model with Problem Based Learning approach toimproving the problem solving skills of students in the class of flat VII buildingmaterials. This research is an experimental research. The sample in thisresearch is VII E (experiment) and VII F (control). The results showed that: (1)learners using learning model Team Assisted Individualization Type WithProblem Based Learning Approach achieved mastery of 80.55% more than75% with complete criterion 75, (2) test results influence motivation andresponsibility to the ability of problem solving has a great influence of 84.4%,(3) the difference test results show the difference of the average value of theexperimental class problem solving ability of 78.28 is better than the controlclass of 68.90, (4) the improvement test results show the problem solving abilityof the class experiments increased with a gain value of 0.618 in the mediumcategory. Based on these four things, it shows that the learning model of TeamAssisted Individualization Type with Problem Based Learning Approach toImproving Student Problem-solving Ability of Class VII Building MaterialDeveloping Material is effective.Keywords: Team Assisted Individualization, Problem Based Learning, ProblemSolving

Abstract

This study aims to determine the effect of supplementation with Moringa oleifera leaf flour as a source of carotenoids on the level of color brightness, growth rate, and survival of koi fish seeds (Cyprinus rubrofuscus). The research design was a Completely Randomized Design (CRD), with 4 treatments and 3 replications. Treatments A (without Moringa leaf flour supplementation), B (100 grams Moringa leaf flour supplementation/kg feed), C (200 grams Moringa leaf flour supplementation/kg feed), and D (300 grams Moringa leaf flour supplementation/kg feed). The results of the study showed that supplementation with Moringa leaf flour as a source of carotenoids in feed, although it did not (yet) have a significant effect on the color brightness of koi fish seeds (P>0.05) because the dose given was thought to be still insufficient, had a significant effect on absolute growth and survival to Koi fish seeds (P<0.05). It can be concluded that Moringa leaf flour can be used as an alternative supplement source of carotenoids to increase the brightness of koi fish color. However, the correct and optimal dosage still needs further research.

Abstract

This study examines the relevance of Mohammad Hatta’s concept of economic democracy through the lens of Islamic economics and the maqāṣid al-sharīʿah. It departs from the persistence of structural inequality, the dominance of large capital, and limited access of lower-income groups to productive resources in Indonesia, conditions that diverge from Hatta’s vision of a people’s economy. Using a qualitative descriptive method and library research, the study analyzes Hatta’s ideas on cooperatives, people’s sovereignty over resources, and state control of strategic sectors, and maps them onto the dimensions of ḥifẓ al-māl (protection of property), ḥifẓ al-nafs (protection of welfare/life), and ḥifẓ al-ijtimā‘/al-‘adl (social justice). The findings show strong substantive alignment between Hatta’s thought and Islamic economic principles while highlighting the need to operationalize them through sharia-based cooperatives, productive zakat, and distribution-oriented fiscal policies to build a more inclusive and just economic model for Indonesia.
