The Distribution Food Consumption Among The Family Members at Economic Crisis In Two IDT Villages In Subang District.The economic crisis in Indonesia has decreased the purchasing power of the families which further affected the household food consumption. The objective of this study is to observe the effect of economic crises on the intra-household food distribution, particularly the poor families. In other words, the objective of the study is to identify which of the family members that affected most by the crises. The socioeconomic status and food consumption data was collected from 100 households in two poor villages in the district of Subang, West Java. There were two rounds of data collection. The first data collection was carried out in August 1998 to represent the "paceklik" period, and the second data collection was carried out in November 1998 to represent the "harvest" period. The food consumption data of the individual family member was collected using "Weighing" method for two days. Nutrition intake was calculated based on Indonesian food composition table. The result showed that the energy and protein intake of individual family members in the periods of "paceklik" and "harvest" was still adequate (>90% RDA). The energy intake of all family members was not significantly different in two periods. However, there was a significant decrease in protein intake of the adult members from "paceklik" period to "harvest" period. While, for the underfives and school age children the protein intake was relatively stable in both periods. This study conclude that the most protected members of family in term of protein intake were children underfive years of age and school age children, whereas, the adult members were the most affected by the changes in the agricultural cycle.Keywords: Food Consumption, Economic Crises

Islamic Religious Education (PAI) plays a crucial role in shaping students’ character and religious values, including moderate attitudes in practicing religion. This study aims to analyze the implementation of Project Based Learning (PBL) in PAI as a means to strengthen moderate character and integrate religious moderation values through student collaborative projects. The research employs a literature review approach, collecting data from various scientific literature, journals, books, theses, and dissertations relevant to the topic. Data analysis is conducted using content analysis and narrative synthesis, applying both deductive and inductive reasoning. The findings indicate that PBL allows students to actively engage in contextual real-life projects, making the understanding of Islamic teachings more applicable and reflective. PBL also promotes the internalization of religious moderation values through collaboration and discussion among students, while reinforcing moderate character by developing social skills, empathy, and inclusive attitudes. Despite challenges such as limited resources and teacher readiness, appropriate implementation strategies can optimize the effectiveness of PBL in PAI. Therefore, PBL functions not only as a learning method but also as a transformative pedagogical strategy that shapes a generation of Muslim students who are knowledgeable, tolerant, and moderate.

Penelitian ini bertujuan untuk menganalisis pengaruh Electronic Word of Mouth (eWOM) dan media sosial terhadap keputusan pembelian konsumen di Kecamatan Maro Sebo Ilir, Kabupaten Batanghari. Pendekatan yang digunakan adalah kuantitatif dengan jenis penelitian asosiatif kausal. Sampel penelitian sebanyak 100 responden dipilih menggunakan teknik purposive sampling, yaitu konsumen yang aktif menggunakan media sosial dan memiliki pengalaman membeli produk secara online. Data dikumpulkan melalui kuesioner online yang diukur menggunakan skala Likert 1–5, kemudian dianalisis dengan regresi linear berganda untuk menguji pengaruh parsial dan simultan variabel eWOM dan media sosial terhadap keputusan pembelian. Hasil penelitian menunjukkan bahwa eWOM berpengaruh positif dan signifikan terhadap keputusan pembelian konsumen (B = 0,482; t = 5,23; p = 0,000), sedangkan media sosial juga berpengaruh positif dan signifikan (B = 0,376; t = 4,12; p = 0,000). Selain itu, pengaruh simultan eWOM dan media sosial terhadap keputusan pembelian juga signifikan (F = 45,87; p = 0,000), yang menunjukkan bahwa kedua variabel secara bersama-sama lebih efektif dalam mendorong keputusan pembelian dibandingkan pengaruh masing-masing variabel secara terpisah. Temuan ini menegaskan pentingnya strategi pemasaran digital yang memadukan eWOM dan media sosial untuk meningkatkan minat dan keputusan pembelian konsumen. Penelitian ini memberikan implikasi praktis bagi pelaku usaha dalam merancang kampanye pemasaran berbasis media sosial dan rekomendasi konsumen digital.
