Abstract

Land-use change from the forest to others will affect the soil’s physicochemical properties. The research was conducted to identify soil physicochemical properties affected by land-use change in Sungai Batang, the east-south part of Maninjau caldera. The research used a survey method from which soil was sampled at four different types of land use (forest, bushland, mixed garden, and paddy soil) at 0-30 cm depth with three replicates. The results show that the soil in Sungai Batang was still developing. It was indicated by coarse soil texture (clay loam to sandy clay loam). Land-use change from the forest to other uses has altered some soil physicochemical properties. It increased soil bulk density and decreased total soil porosity, permeability rate, SOM content, and  total-N. However, there was an increase in  soil characteristics, especially soil P-availability, CEC, Ca-  and Na-exchangeable . While the soil pH  (H2O), K-and Mg-exchangeable stayed the same. In general, land use changed from forest to other use, mostly farming land degraded physicochemical characteristics of the soil derived from volcanic materials in Sungai Batang. That was mainly due to the decrease in SOM content.

Abstract

This systematic literature review examines the integration of policy and technology in vocational educational leadership, focusing on studies published between 2022 and 2024. The review addresses four key research questions: (1) technological tools and advancements supporting leadership in vocational education, (2) the influence of policies and frameworks on leadership strategies, (3) challenges associated with integrating policy and technology, and (4) the socio-economic and educational impacts of this integration. The findings reveal that technological tools such as Learning Management Systems (LMS), digital collaboration platforms, and advanced technologies like Artificial Intelligence (AI) and Virtual Reality (VR) are instrumental in enhancing leadership and educational outcomes. Policies promoting digital transformation, industry alignment, and inclusivity significantly shape leadership strategies. However, challenges like infrastructure limitations and policy-implementation gaps persist. Effective integration of policy and technology in vocational education leads to improved learning environments, better skill acquisition, and enhanced socio-economic outcomes, though ensuring equitable access remains a critical concern. This study provides a comprehensive understanding of how policy and technology intersect to shape vocational education leadership in contemporary settings.Keywords: Vocational Leadership, Policy Integration, Educational Technology, Digital Transformation

Abstract

Penelitian bertujuan untuk menganalisis perbandingan pengaruh pencampuran bahan bakar biosolar dengan dexlite terhadap kinerja mesin diesel mitsubishi L300. Jenis penelitian ini adalah penelitian dengan pendekatan kuantitatif dengan menggunakan Metode penelitian eksperimental. Penelitian ini menggunakan dua variabel yaitu satu variabel independent (bebas) dan variabel dependent (terikat). Instrumen yang digunakan pada penelitian ini yaitu berupa alat chassis dynamometer. Subjek pada penelitian ini yaitu pengaruh rasio pencampuran bahan bakar dexlite dengan biosolar terhadap torsi dan daya pada mesin diesel Mitsubishi L300. Berdasarkan hasil pengujian, perhitungan dan pengolahan data serta analisis data yang dilakukan pada performa mesin diesel Mitsubishi L300 pada bahan bakar dexlite rasio 1:0, biosolar rasio 1:0, dexlite dengan biosolar rasio 7:3, dan dexlite dengan biosolar rasio 3:7, maka didapatkan kesimpulan bahwa pada bahan bakar dexlite dengan biosolar rasio 7:3 memang lebih unggul didalam performa mesin dengan selisih yang sedikit dibandingkan dengan bahan bakar biosolar 1:0, maka dapat disimpulkan bahwa penggunan bahan bakar biosolar 1:0 lebih efisien dan signifikan dari sampel bahan bakar lainnya.

Abstract

Suhu motor BLDC berpengaruh langsung pada umur dan fungsionalitasnya. Suhu rotor mempengaruhi efektivitas magnet permanen, sementara suhu belitan stator berdampak pada ketahanan isolasi. Pembuangan panas yang tidak efisien dapat menyebabkan overheating, yang berpotensi mengakibatkan demagnetisasi, kerusakan isolasi, peningkatan kehilangan panas, penurunan efisiensi, dan masa pakai motor yang lebih pendek. Penelitian ini bertujuan untuk menganalisis pengaruh kecepatan aliran udara dalam sistem pendingin terhadap temperatur kerja pada Motor BLDC Tipe Permanen Magnet Fluks Aksial menggunakan fitur (CFD) Computational Fluid Dynamic pada aplikasi Ansys Fluent 2024 R1 Student Version. Motor BLDC yang digunakan dalam penelitian ini terdiri dari beberapa komponen utama, yaitu winding, stator, rotor, dan casing. Simulasi dilakukan untuk memodelkan perpindahan panas konveksi dan konduksi dalam motor pada variasi kecepatan aliran udara sebesar 10 m/s, 20 m/s, dan 30 m/s yang diberi sumber panas berasal dari Heat Loss komponen winding dan stator pada putaran 5000 RPM. Hasil simulasi menunjukkan bahwa peningkatan kecepatan aliran udara secara signifikan menurunkan suhu pada komponen-komponen motor. Suhu tertinggi pada winding, casing dan rotor secara berurut tercatat sebesar 367,83 K, 364,26 K, 360,69 K pada kecepatan aliran 10 m/s, dan menurun menjadi 339,04 K, 336,99 K, 332,88 K pada kecepatan 30 m/s. Perpindahan panas dalam motor terjadi melalui dua mekanisme utama: konduksi, yang mendominasi pada area kontak antar komponen, dan konveksi, yang mempengaruhi pendinginan komponen oleh aliran udara di sekitarnya. Velocity contour menunjukkan bahwa kecepatan fluida yang rendah terjadi di sekitar casing, yang mengindikasikan adanya area dengan perpindahan panas yang kurang optimal.

Abstract

This study aimed to enhance the quality of Shield Metal Arc Welding instruction in Class XI Welding Engineering at State Vocational High School 1 Bukittinggi through the integration of interactive media videos. Employing a class action research design with saturated sampling, the research findings revealed that the implementation of video tutorials significantly improved student motivation and learning outcomes. The use of video tutorials captured students' interest, resulting in increased motivation for learning Shield Metal Arc Welding. In the initial cycle, student motivation in Class XI Welding Engineering at State Vocational High School 1 Bukittinggi, as measured in meeting I, stood at 54%, indicating a less motivated state. By meeting II of cycle I, the motivation increased to 61%, categorized as moderately motivated. In the subsequent cycle, meeting I recorded a motivation level of 72%, demonstrating a motivated state, while meeting II in cycle II reached 82%, indicating a highly motivated state. Consequently, there was a noticeable progression in student learning motivation from cycle I to cycle II. Furthermore, student learning outcomes in Shield Metal Arc Welding for Class XI Welding Engineering at State Vocational High School 1 Bukittinggi improved when videos were utilized as interactive media. In cycle I, the average student learning outcome was 77.88, categorized as moderate. In cycle II, the average increased to 79.06, reflecting a high level of achievement. This indicates a positive shift in student learning outcomes, moving from moderate to good performance.
