Abstract

This research aims to evaluate the effectiveness of ice gel packs based on tapioca flour mixed with natural ingredients such as vinegar, lemon and lime as a cooling alternative. Ice gel pack is made through a process of mixing the ingredients until homogeneous, heating to form a gel, and freezing. Characteristic tests carried out include pH, freezing time, and temperature changes. The research results show that the acidity level of ingredients affects product performance. Ice gel packs with lime have the lowest pH (pH = 2) and show the best ability to maintain cold temperatures, while vinegar with the highest pH (pH = 4) freezes the fastest but is less effective in maintaining temperature. This research proves that a combination of natural ingredients can produce ice gel packs that are environmentally friendly, efficient, and have wide application potential as a modern cooling solution.

Abstract

Pembelajaran IPA pada topik bentuk dan perubahan energi kerap menimbulkan kesulitan bagi siswa karena konsep yang dipelajari bersifat abstrak dan tidak didukung media visual yang memadai. Berdasarkan permasalahan tersebut, penelitian ini bertujuan mengkaji sejauh mana simulasi digital PhET efektif digunakan sebagai media pembelajaran interaktif melalui kajian literatur. Penelitian menggunakan pendekatan kualitatif dengan metode studi literatur terhadap sejumlah artikel ilmiah yang membahas penggunaan PhET dalam pembelajaran IPA. Proses analisis dilakukan dengan teknik analisis isi untuk mengidentifikasi temuan, metode, dan hasil penelitian yang berkaitan dengan efektivitas media tersebut. Hasil telaah menunjukkan bahwa PhET mampu meningkatkan penguasaan konsep, hasil belajar, serta kemampuan berpikir kritis peserta didik melalui penyajian visual yang konkret, interaktif, dan memungkinkan eksplorasi mandiri. Selain itu, media ini turut meningkatkan motivasi, minat belajar, dan keaktifan siswa karena memberikan pengalaman belajar yang dekat dengan eksperimen nyata. Di sekolah dengan fasilitas laboratorium terbatas, PhET juga dapat menjadi alternatif praktikum yang efektif. Oleh karena itu, penggunaan simulasi PhET dinilai mampu meningkatkan kualitas pembelajaran IPA pada materi energi dari aspek kognitif maupun afektif. Pengintegrasian PhET ke dalam model pembelajaran berbasis inkuiri atau eksplorasi disarankan untuk memperkuat keterlibatan siswa dalam memahami konsep secara mendalam.

Abstract

Javanese society is known to have a complex and deep belief system, which has been passed down from generation to generation. This study uses a qualitative approach, which was conducted in the Gang Ikla Complex, Jalan Pancing III, Indra Kasih Village, Medan Tembung District. The purpose of this study is to analyze the main factors that influence belief in traditions and myths in Javanese society, as well as the influence of belief in this tradition on social life, decision making, and the behavior of Javanese society. Data collection techniques used in-depth interviews and observations. Data analysis was carried out using Narrative Analysis. Data analysis was carried out by comparing and linking field data with relevant sources from books and journals so that relevant research results were obtained. The results of the study indicate that superstition is not only considered a cultural heritage passed down from ancestors, but also functions as a guideline for life that helps society maintain important norms and values, in addition there are factors that influence people's beliefs.
