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

Penelitian ini dilakukan dengan tujuan menganalisis pengaruh penggunaan media simulasi interaktif PhET (Physics Education Technology) terhadap peningkatan hasil belajar IPA pada materi Gelombang siswa kelas VIII SMP. Latar belakang utama penelitian ini didasarkan pada tantangan yang dihadapi dalam pembelajaran IPA, di mana konsep-konsep yang bersifat abstrak seperti Gelombang, sering menjadi hambatan utama yang menyebabkan rendahnya hasil belajar kognitif siswa. Untuk mencapai tujuan tersebut, penelitian ini menggunakan metode Kajian Pustaka Sistematis (Systematic Literature Review), di mana berbagai temuan dari penelitian-penelitian eksperimen dan literatur terdahulu yang relevan mengenai penggunaan PhET pada jenjang SMP dianalisis dan disintesis secara mendalam. Hasil sintesis literatur secara konsisten menunjukkan bahwa penerapan media simulasi PhET memberikan kontribusi positif dan signifikan terhadap peningkatan hasil belajar IPA siswa SMP, dengan tingkat efektivitas yang optimal pada jenjang ini, bahkan memiliki nilai effect size yang lebih tinggi dibandingkan jenjang lainnya. Secara spesifik, media PhET terbukti efektif dalam memfasilitasi visualisasi konsep abstrak seperti gelombang berjalan dan gelombang stasioner, serta meningkatkan keterampilan proses sains dan pemahaman konseptual pada materi Getaran dan Gelombang. Disimpulkan bahwa media simulasi PhET memiliki pengaruh positif yang kuat dalam meningkatkan hasil belajar IPA materi Gelombang, dan direkomendasikan untuk diintegrasikan sebagai solusi inovatif dalam mengatasi kesulitan pembelajaran konsep abstrak.

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.
