Abstract

Massive technological development is something that cannot be avoided in this life, because technological development is in line with scientific progress. Indonesia is a country that has abundant energy of various kinds source. Currently, energy use in Indonesia still comes from oil and gas earth, as well as coal which is non-renewable resources. Dependence on energy becomes main problem in energy supply national. Considering the need for it fuel every year continues has increased and is necessary anticipation of the availability of energy sources which is getting thinner while the price fuel oil increases. Every country in the world is now focusing on energy production through non-conventional sources. Biomass is an alternative energy source to replace fossil fuels (oil earth) because it has several beneficial properties, including being able to be utilized economically sustainable because of its renewable nature, no contains sulfur so the biomass does not cause air pollution. Besides being able to reduce waste, if managed properly biomass has high potential to be used as an alternative energy source in the form of biobriquettes. The method used in this research includes the preparation of salak skin raw materials, the carbonisation stage of salak skin, the starch adhesive preparation stage and the salak skin analysis stage, namely the analysis of calorific value and burning rate. Based on the results of the calorific value analysis and combustion rate analysis, it can be concluded that the biobriquette sample of salak skin with starch adhesive has met the provisions of the SNI No. 01-6235-2000 on charcoal biobriquettes. From the results of the study, it was also found that the Biobriket B sample, namely by using adhesive, has a high calorific value and burning rate compared to Biobriket A, namely without using adhesive.

Abstract

Learning biology, particularly on the topic of cells, often poses challenges for students due to its abstract nature. In addition, the instructional media commonly used in the classroom remain simple and less interactive, which reduces students’ interest and limits their understanding. This condition affects learning outcomes that tend to be unsatisfactory. This study aims to develop an e-booklet learning media based on flipbook maker and to evaluate its feasibility, students’ responses, and its effect on improving learning outcomes. The research employed the Research and Development (R&D) method using the ADDIE model, which consists of analysis, design, development, implementation, and evaluation stages. The subjects were eighth-grade students of MTs Muhammadiyah 25 Marubun Jaya. Data were collected through expert validation sheets, student response questionnaires, and learning achievement tests. The results indicate that the developed e-booklet achieved an average feasibility score of 90% (categorized as “very feasible”) and received student responses of 88% (categorized as “very good”). Moreover, students’ learning outcomes improved after using the developed media. Therefore, the flipbook maker-based e-booklet is considered effective and feasible to be implemented as an alternative learning medium in biology, particularly in the topic of cells.

Abstract

Pendidikan Hak Asasi Manusia (HAM) memiliki peran strategis dalam membentuk sikap sosial siswa, khususnya di lingkungan sekolah yang multikultural. Penelitian ini bertujuan untuk menganalisis hubungan antara pemahaman siswa tentang Hak Asasi Manusia dengan sikap sosial siswa kelas XII di SMA Swasta Utama Medan. Penelitian ini menggunakan pendekatan kuantitatif dengan desain deskriptif korelasional. Sampel penelitian terdiri atas 80 siswa yang dipilih menggunakan teknik simple random sampling. Data dikumpulkan melalui angket pemahaman HAM dan sikap sosial yang telah diuji validitas dan reliabilitasnya, kemudian dianalisis menggunakan statistik deskriptif, korelasi Pearson, dan regresi linear sederhana. Hasil penelitian menunjukkan bahwa pemahaman siswa tentang HAM berada pada kategori cukup baik hingga baik, sedangkan sikap sosial siswa secara umum berada pada kategori positif. Analisis korelasi menunjukkan adanya hubungan positif dan signifikan antara pemahaman HAM dan sikap sosial siswa (r = 0,68; p < 0,01). Hasil analisis regresi mengungkapkan bahwa pemahaman HAM memberikan kontribusi sebesar 38,6% terhadap variasi sikap sosial siswa. Aspek penerapan HAM dalam kehidupan sehari-hari memberikan pengaruh paling dominan terhadap sikap sosial, sementara aspek pemahaman prinsip teoretis HAM menunjukkan kontribusi yang lebih rendah. Penelitian ini mengindikasikan pentingnya penguatan pendidikan HAM berbasis praktik dan kontekstual dalam pembelajaran guna membentuk sikap sosial siswa yang toleran, empatik, dan berkeadilan sosial.

Abstract

Simalungun Regency has 32 sub-districts covering an area of 438,660 hectares, representing 6.12% of the total area of North Sumatra province. There are 386 villages (nagori) and 27 sub-districts (kelurahan). In Pematang Bandar District, corn and rice are commonly cultivated. In Balata Village, Jorlang Hataran District, farmers are organized into the "Harapan Jaya" farmer group and prefer to cultivate corn. Corn prices in the Indonesian market are unstable, impacting farmers' incomes. Training in processing corn into food is needed to increase their income. This training encompasses skills in production and marketing. Digital marketing training can help farmers promote their products and expand their marketing reach. Corn is an important commodity in Indonesia, serving as a source of food, animal feed, and industrial raw materials. Corn is also a staple food in some regions and is used in various industries. Corn mills are essential post-harvest tools to increase corn's added value, improve production efficiency compared to manual methods, and support food security. However, many farmers in Indonesia still use traditional methods with low productivity and lack knowledge of crop processing and marketing strategies. Farmers face various challenges, such as limited access to information and price fluctuations. Capacity building through training is needed to improve production and marketing. The "Harapan Jaya" farmer group focuses on corn cultivation and sales, but has not yet maximized the added value of their harvest.
