Abstract

Penelitian Bertujuan adalah mengevaluasi mutu briket melalui pengukuran nilai kalor, kandungan air, dan kadar abu pada enam sampel berbeda. Dari hasil analisis, sampel K-A1, yang mengandung 77% kulit kemiri dan 3% bahan perekat, mencatatkan nilai kalor tertinggi, yaitu 6562 kkal/kg. Seluruh sampel yang diuji menunjukkan nilai kalor di atas 5000 kkal/kg, melampaui ketentuan standar nasional (SNI). Selain itu, kadar abu pada sampel K-A1 sebesar 6,78%, masih dalam batas toleransi SNI yang memperbolehkan kadar abu hingga 8%. Dalam aspek kadar air, sampel K-A3 (97% kulit kemiri dan 3% perekat) mencatat angka 5,78%, sedangkan sampel C-A3 dan K-A2 masing-masing memiliki kadar air 6,46% dan 7,59% — semuanya memenuhi syarat kadar air di bawah 8% menurut SNI. Berdasarkan keseluruhan parameter, briket dari sampel K-A1 dinilai sebagai yang terbaik, dengan kombinasi nilai kalor 6562 kkal/kg, kadar abu 6,78%, dan kadar air 9,07%.

Abstract

Environmental Physics concepts are very likely to be explored to facilitate the cultivation of spiritual attitudes because they are closely related to phenomena in everyday life. Visual media can help visualize environmental phenomena so that they are easier to understand. This study aims to instill spiritual values through the concept of Environmental Physics as an alternative learning that focuses on the affective domain with the help of visual media. This study involved 15 science education postgraduate students. This research used a Pre-experimental design with a Shoot Case Study. The research design includes pre-experiment, experiment, and analysis of experimental data results. In the pre-experiment stage, the concept of environmental physics and spiritual attitudes were analyzed, learning tools were prepared, and questionnaire instruments for student perceptions related to the cultivation of spiritual values were prepared. At the experimental stage, the implementation of Environmental Physics learning integrated with spiritual values was carried out. In the post-experiment stage, data analysis and interpretation were carried out to answer research problems. Based on the results of data analysis, it is known that 92.15% of respondents strongly agree that learning environmental physics can instill awareness of the nature of God. Based on the results of the open-ended questionnaire, it is known that students can explain the content of spiritual values in various phenomena in the environment. In addition, students stated that visual media can facilitate the activity of instilling awareness that God is omnipotent over all the universe. Thus it can be concluded that environmental physics learning activities can instil spiritual attitudes through environmental physics content assisted by visual media. Science content, especially environmental physics, is very relevant in instilling spiritual values

Abstract

Tujuan dari penelitian ini adalah untuk mengkaji literatur yang ada tentang peran administrasi sekolah dalam mendukung implementasi kurikulum yang efektif. Metode dengan melakukan tinjauan pustaka yang komprehensif dengan memanfaatkan basis data seperti Scopus dan Google Scholar. Artikel yang diterbitkan dari tahun 2019 hingga 2024 dan kriteria inklusi dan eksklusi juga disertakan. Pemilihan artikel untuk dikaji menggunakan panduan Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). Studi yang membahas peran administrasi sekolah dalam mendukung implementasi kurikulum ditemukan memiliki keterbatasan dalam generalisasi temuan, potensi bias dalam pengumpulan data, serta ketidaklengkapan dalam menjelajahi variabel atau tantangan yang relevan dalam konteks geografis masing-masing. Penelitian selanjutnya dapat memperhatikan diversitas konteks, penggunaan metode campuran (kuantitatif dan kualitatif), dan pengurangan bias dalam pengumpulan data. Penelitian yang lebih luas dan lebih mendalam akan memberikan pemahaman yang lebih komprehensif dan aplikatif mengenai tantangan dan praktik terbaik dalam pendidikan dan administrasi sekolah. Selain itu, ditemukan peran administrasi sekolah dalam mendukung implementasi kurikulum seperti pengelolaan sarana dan prasarana, pengaturan jadwal dan alokasi waktu, manajemen sumber daya manusia, dukungan teknologi dan inovasi, monitoring dan evaluasi pelaksanaan kurikulum, pengelolaan anggaran dan penciptaan lingkungan yang kondusif. Administrasi yang kuat dan terorganisir dengan baik akan memastikan bahwa proses pembelajaran berjalan lancar dan sesuai dengan tujuan kurikulum, sehingga menghasilkan lulusan yang berkualitas dan mampu bersaing dalam berbagai bidang.

Abstract

The purpose of this study is to make snake fruit briquette charcoal mixed with goat dung an alternative energy source that supports environmentally friendly technology. The samples used were snake fruit and goat dung as charcoal and tapioca flour as an adhesive. Each sample has 200 grams of charcoal and 30 grams of adhesive. The percentage of charcoal is 50% snake fruit bark charcoal and 50% goat dung charcoal. Snake fruit briquettes and goat dung are divided into 3 groups: A1 (87% charcoal: 13% adhesive), A2 (77% charcoal: 23% adhesive), and A3 (97% charcoal: 3% adhesive). In 3 samples tested with the percentage of charcoal flour to tapioca flour, the first one was produced in sample A1 (87%: 13%), which produced a moisture content of 9.87%, an ash content of 36.75%, and a calorific content of 5899 kcal/kg. The A2 sample (77%:23%) yielded a moisture content of 11.44%, an ash content of 32.13%, and a calorific content of 5634 kcal/kg. The A3 sample yielded a moisture content of 8.93%, an ash content of 41.38%, and a calorific content of 6339 kcal/kg.  This study concludes that the best calorific value in the A3 sample is 97% charcoal briquettes with 3% adhesive, with a calorific value of 6339 cal/kg.
