Abstract

Material A573 Grade 70 is one type of material used to manufacture pressure vessel shells or walls. The thickness of the shell depends on the required pressure design for production. In a case study on pressure vessel shell manufacturing, a thickness of 36 mm was used near the manhole. Due to the connection between the shell and the manhole, the material A573 Grade 70 in the shell was subjected to heat influence. The shell near the manhole will be connected to the rest of the shell using the same material, A573 Grade 70. Consequently, it was necessary to analyse the heat treatment for this material. The heat treatments used to determine the microstructure and hardness value were Preheat and Post Weld Heat Treatment (PWHT). Both types of heat treatments were employed. The preheat temperatures varied at 120°C, 150°C, and 200°C for each joint undergoing PWHT at 650°C with a holding time of 60 minutes, as well as for joints without PWHT. The microstructure of variations with preheat and PWHT exhibited finer grains compared to variations without PWHT. The highest recorded hardness value among the variations with PWHT was 209.89 HVN in the weld metal for the 150°C preheat variation. The highest recorded hardness value among the variations without PWHT was 235.07 HVN in the weld metal for the 200°C preheat variation

Abstract

The cocoa plant is the main ingredient in the manufacture of chocolate and its de-rivative products. The demand for cocoa derivative products is always high in line with the globalization of food and beverages made from chocolate. Traditional co-coa cultivation techniques are the main priority for farmers and the handling of Vascular Streak dieback (VSD) pests is a top priority for farmers. The purpose of this service is to improve the economy of cocoa farmers in Poli-Polia Village, Poli-Polia District, East Kolaka Regency. The method used is discussion, practice and demonstration material. The results of the shoot grafting technique for cacao seed-lings and the manufacture of organic fertilizers increase the productivity of cocoa plants and the results of turmeric extract can directly deal with VSD diseases that attack cocoa plants. In practice, the method of processing and the efficacy of tur-meric extract is the cause of not developing VSD disease in cocoa plants. On the other hand, cocoa yields can be sold at a high value based on training in harvesting techniques and how to improve the quality of cocoa beans.

Abstract

Energy consumption (kWh) is critical to the operation of electrical systems. Predictive modeling optimizes energy usage, increasing power system efficiency. This study created an artificial neural network (ANN) architecture to estimate energy consumption (kWh) for home users in Banda Aceh. The ANN topology consisted of 5 input layers, 5-25 hidden layers, and one output layer. This study used two scenarios: first, the ANN topology was trained using the logsig activation function, and then the tansig activation function was used for training. Based on training simulations, the ANN architecture with 5 input layers, 5 hidden layers, and 1 output layer has the lowest Mean Squared Error (MSE) of 0.00035. The next phase involved testing this ANN topology. The next stage is to analyze the ANN architecture with 5 input layers, 5 hidden layers, and 1 output layer using the testing technique. Based on the testing technique, the ANN architecture with 5 input layers, 5 hidden layers, and 1 output layer had a MAPE value of 3.34%.

Abstract

This paper reports the outcomes of a ‘Community Service’ activity related to the integration of technology in English language teaching in Indonesia in the 21st century. The activity was conducted for junior high school English language teachers in Depok District, Indonesia. It outlines the opportunities and challenges faced by teachers in incorporating technology into their teaching and learning processes. Key themes emerging from the activity, include enhancing English language proficiency, increasing engagement and motivation, developing 21st-century skills, cultural exchange and global awareness, as well as the role of teachers and professional development. However, the effectiveness of technology integration heavily relies on the teachers' proficiency, availability of infrastructure, and pedagogical adaptation. The findings of the activity highlight the importance of comprehensive teacher training programs, improvements in educational infrastructure, and a pedagogical shift towards a curriculum more inclusive of technology. Recommendations include enhancing collaboration among stakeholders to support a technology-enriched learning environment to meet the evolving needs of learners in Indonesia.

Abstract

This paper reports the outcomes of a ‘Community Service’ activity related to the implementation of the Deep Learning (DL) approach in English language teaching in Indonesia. The activity was conducted for junior high school English language teachers in Bogor regency, Indonesia. It outlines the design, implementation, and evaluation of a structured professional development program aimed at equipping teachers with the knowledge, skills, and reflective capacity needed to adopt Deep Learning within the framework of Indonesia’s Merdeka Belajar curriculum. Drawing on Michael Fullan’s 6Cs framework (i.e., character, citizenship, collaboration, communication, creativity, and critical thinking), the activity emphasized pedagogical transformation that moves beyond traditional content delivery toward student-centered, inquiry-based learning. The program adopted a four-stage model: observation, socialization, training and mentoring, and evaluation. These stages allowed facilitators to map the instructional realities of the participants, co-construct relevant training content, and evaluate the impact through both qualitative and quantitative measures. The results indicated a significant increase in teachers’ awareness of DL principles, improved pedagogical confidence, and willingness to implement more meaningful and contextualized English Language Teaching (EFL) practices. Key themes explored included the coherence between DL and the national Profil Pelajar Pancasila, strategies to overcome implementation challenges, and the integration of AI tools to enhance 21st-century competencies. The findings suggest that DL offers a transformative avenue for revitalizing ELT in Indonesia by aligning global educational innovations with local policy goals. This paper recommends sustained investment in teacher training, digital infrastructure, and curricular alignment to ensure scalable and equitable adoption of DL nationwide.

Abstract

Kelembagaan Badan Nasional Pengelola Perbatasan (BNPP) sebagai institusi koordinatif pembangunan wilayah perbatasan Indonesia menghadapi berbagai persoalan normatif dan struktural yang menghambat efektivitas kerjanya. Permasalahan utama terletak pada status subordinatif BNPP di bawah Kementerian Dalam Negeri yang melemahkan posisi kelembagaan, ditambah dengan defisit kewenangan regulatif dan absennya kerangka hukum yang mengikat kementerian teknis. Penelitian ini bertujuan untuk mengkaji ulang konstruksi hukum BNPP dalam arsitektur kelembagaan pembangunan nasional dengan menekankan pentingnya reposisi yuridis kelembagaan guna memperkuat fungsi koordinatif dan akuntabilitasnya. Pendekatan yang digunakan adalah yuridis-normatif dengan metode analisis deskriptif-kualitatif dan didukung oleh studi perundang-undangan, dokumen kebijakan, serta literatur akademik terakreditasi. Hasil analisis menunjukkan bahwa ketiadaan otoritas hukum yang kuat menyebabkan fragmentasi kebijakan antar kementerian, ketimpangan relasi pusat-daerah, serta rendahnya partisipasi subnasional dalam perencanaan pembangunan perbatasan. Evaluasi kebijakan pun belum terintegrasi dalam siklus kebijakan BNPP, sehingga keberhasilan hanya diukur dari output fisik tanpa memperhatikan dampak sosial dan geopolitik. Penelitian ini merekomendasikan perlunya pembentukan Undang-Undang Pengelolaan Perbatasan yang memberikan kewenangan regulatif kepada BNPP, reposisi kelembagaan agar lebih otonom, penguatan mekanisme evaluasi berbasis data spasial dan sosial, serta peningkatan partisipasi daerah dalam proses pengambilan keputusan. Reposisi hukum kelembagaan BNPP bukan sekadar kebutuhan administratif, melainkan agenda strategis untuk mewujudkan tata kelola perbatasan yang adil, integratif, dan konstitusional.
