Abstract

The ideas of civic empowerment have transformed the discourse on sustainable suburban development, particularly through the active involvement of young people and the use of digital participatory media. This study, conducted in Manglayang, Bandung, employs an observational method using participatory action research to explore pathways toward the final evolutionary stage of sustainable development, focusing on rural agriculture and social, legal, and welfare citizenship. The research identifies key typologies of youth engagement in sustainable development, including social empowerment, entrepreneurship, and millennial agricultural movements, all facilitated by digital participatory media platforms. It also highlights a redefined notion of youth citizenship, emphasizing membership and participation in both civil and economic spheres through voluntary and profit-oriented activities. The findings reveal that this active, empowered form of citizenship, supported by digital participatory media, is a critical driver of modernization and sustainable economic development in Manglayang, Bandung.

Abstract

Abstrak: Dalam rangka menjamin ketersediaan energi dan menjaga kelestarian lingkungan, penerapan energi bersih dan berkelanjutan (sustainable) adalah isu yang sangat penting. Manajemen penggunaan energi yang efisien harus diperkenalkan kepada generasi muda sedini mungkin. Tujuan kegiatan ini adalah untuk meningkatkan pemahaman siswa mengenai teknologi pemantauan energi pintar dan kesadaran mereka tentang efisiensi energi. Metode kegiatan yang digunakan adalah penjelasan teori dan praktik perakitan sistem berbasiskan teknologi IoT. Peserta kegiatan ini adalah siswa menengah kejuruan Program Keahlian Teknik Instalasi Tenaga Listrik. Karenanya, materi pelatihan ini sangat lah penting untuk mendukung bidang keahlian mereka dalam dunia kerja nantinya. Sistem evaluasi yang digunakan adalah survei dengan 11 pertanyaan dalam bentuk angket yang diisi oleh para peserta di akhir sesi pelatihan. Berdasarkan hasil evaluasi, sekitar 89% peserta menyatakan "setuju" atau "sangat setuju" bahwa mereka senang dan berminat untuk mempelajari lebih lanjut tentang teknologi sistem pemantauan energi cerdas berbasiskan IoT. Dengan pelatihan ini, diharapkan tingkat kesadaran siswa menengah kejuruan mengenai efisiensi energi menggunakan sistem pemantauan energi pintar dapat meningkat sehingga mereka lebih siap menghadapi Revolusi Industri 4.0 pada dunia kerja nantinya.Abstract: To ensure energy availability and maintain environmental sustainability, the implementation of clean and sustainable energy is a crucial issue. Efficient energy management must be introduced and educated to the younger generation at the earliest possible period. The objective of this activity is to enhance students' understanding of smart energy monitoring technology and their awareness of energy efficiency. The methods used in this activity are theoretical explanations and practical sessions on assembling IoT systems. The participants of this activity were students from the Electrical Power Installation Vocational Program. The evaluation system employed was a survey with 11 questions, which participants completed at the end of the training. Based on the evaluation results, approximately 89% of participants stated that they "agreed" or "strongly agreed" that they were pleased and interested in learning more about Smart Energy Monitoring System based on IoT technology. It is hoped that this training will increase the awareness of the students regarding energy efficiency using smart energy monitoring systems, thus better preparing them to face the Industrial Revolution 4.0.

Abstract

Conventional multipliers in digital systems still face major challenges in the form of high latency, which negatively impacts performance in computationally intensive applications such as digital signal processing (DSP) and artificial intelligence. In addition, limitations in hardware resource efficiency present a significant challenge in designing systems that are both fast and area-efficient. This study aims to analyze the performance of 8-bit multipliers based on the Booth Radix-4 and Vedic (Urdhva Tiryagbhyam) algorithms in terms of speed and resource efficiency. This research adopts a quantitative approach. The research subjects consist of three 8-bit digital multiplier architectures: Shift-and-Add (baseline), Booth Radix-4, and Vedic. Data were collected using a documentation technique with instruments in the form of post-synthesis reports generated by the software, which include parameters such as propagation delay and logic element (LE) utilization. Data analysis was conducted using quantitative comparative analysis. The results show that both advanced algorithms (Booth and Vedic) perform significantly faster than the conventional method. The Booth Radix-4 multiplier demonstrates the best performance, with the lowest delay of 8.114 ns and a resource usage of 139 LEs, while the Vedic multiplier exhibits a delay of 9.298 ns and the highest resource consumption of 219 LEs. The study concludes that the Booth Radix-4 algorithm is the most optimal choice for implementing an 8-bit multiplier, as it provides the best balance between high speed and moderate resource utilization. The implications of this research provide a valuable reference for digital system designers in selecting appropriate multiplier architectures based on application requirements.

Abstract

This study presents a System Dynamics model integrating maritime chokepoint risk in the Strait of Hormuz with mineral-fertilizer supply-chain dynamics, applied to PT Pupuk Indonesia. The problem addressed is that Indonesia's compound-NPK production depends on imported sulfur, phosphate, and potassium, leaving it exposed to a disruption of the Strait of Hormuz through which most of its sulfur supply transits. A continuous-time stock-and-flow model of four raw-material subsystems with first-order sourcing delays, a normalized logistic production response, and a downstream agricultural submodule is validated structurally, parametrically, behaviorally, and under extreme conditions, then analyzed across 2,000 Monte Carlo runs. Under a 180-day total blockade, urea remains fully insulated by domestic gas while NPK is drawn to a critical near-miss trough of 64% as the sulfur buffer falls to 21 equivalent days. Blockade duration and sulfur dependency dominate risk, with 20% of scenarios reaching production halt by day 240, while buffers exceeding 180 days preserve output above 97%. A combined strategy of extended strategic buffer and accelerated alternative sourcing sustains output across all scenarios. We quantify working-capital, fiscal-subsidy, and real-option dimensions and propose a Strategic Sulfur Reserve of about 180 days of consumption as the principal policy contribution for strengthening national food-security resilience.
