Abstract

Generator merupakan komponen penting dalam sistem tenaga listrik yang mengubah energi mekanik dari putaran turbin menjadi energi listrik. Pada penelitian ini, turbin digerakkan oleh angin yang dihasilkan di salah satu puncak gedung di Institut Teknologi Sumatera. Generator dirancang dengan tiga variasi diameter kawat tembaga dalam lilitannya, yaitu 0,15 mm, 0,75 mm, dan 1 mm, untuk mengevaluasi efisiensi daya listrik yang dihasilkan pada putaran rotor rendah. Hasil eksperimen menunjukkan bahwa kawat tembaga dengan diameter 0,15 mm menghasilkan tegangan tertinggi sebesar 744 V, arus 29,6 A, dan daya 22.022,4 W pada putaran rotor yang tertinggi 1500 RPM . Diameter 0,75 mm menghasilkan tegangan 125 V, arus 4,8 A, dan daya 600 W, sedangkan diameter 1 mm menghasilkan tegangan 92 V, arus 3,4 A, dan daya 312,8 W. Dengan demikian, daya tertinggi dihasilkan oleh kawat berdiameter 0,15 mm, menunjukkan bahwa diameter kawat berpengaruh signifikan terhadap output daya generator turbin angin.

Abstract

Pemanfaatan limbah biomassa sebagai sumber energi alternatif merupakan solusi potensial dalam mendukung keberlanjutan energi. Penelitian ini bertujuan untuk mengkaji karakteristik briket berbahan dasar kulit kakao yang dipadukan dengan selulosa asetat dalam tiga variasi komposisi (%), yaitu A (95:5), B (93:7), dan C (90:10). Briket diproses menggunakan tekanan sebesar 60 kg/cm² dan dikeringkan pada suhu 100°C selama 4 jam. Pengujian dilakukan untuk menentukan kadar karbon, kadar zat terbang, kadar abu, nilai kalor, serta laju dan durasi pembakaran. Hasil penelitian menunjukkan bahwa kadar karbon tertinggi diperoleh pada variasi A (79,29%), yang mendekati standar SNI 1683-2021 dengan batas minimal 79%. Kadar zat terbang pada semua variasi memenuhi standar, dengan nilai terendah pada variasi A (7,05%), lebih rendah dari batas maksimal SNI, yaitu 10-17%. Namun, kadar abu masih jauh melebihi standar, dengan variasi C memiliki kadar abu tertinggi (20,83%), sedangkan batas maksimal SNI adalah 4%. Dari segi nilai kalor, seluruh variasi belum memenuhi standar SNI yang mensyaratkan minimal 6500 kal/g, dengan nilai tertinggi hanya mencapai 4671,63 kal/g. Laju pembakaran tertinggi terjadi pada variasi C (0,26 g/menit) dengan waktu pembakaran 69 menit, sementara variasi A memiliki laju pembakaran terendah (0,22 g/menit) tetapi dengan durasi terpanjang (81 menit), menunjukkan efisiensi pembakaran yang lebih baik. Secara keseluruhan, briket kulit kakao dengan selulosa asetat memiliki potensi sebagai bahan bakar alternatif, tetapi masih memerlukan optimasi lebih lanjut untuk meningkatkan nilai kalor dan menurunkan kadar abu agar sesuai dengan standar nasional.

Abstract

Small-scale renewable energy use is crucial for supplying the world's electrical needs. Utilizing these renewable energy sources requires a device that can transform mechanical power into electrical power. The purpose of this research is to construct a simple AC generator by converting mechanical power into electricity by varying the copper wire's diameter and rotational speed. The outcomes of the investigation include information on the electrical power, torque, mechanical power, and efficiency of the generator. The technical details of the generator employed are 12 poles, a rotor diameter of 9.25 cm, and a stator diameter of 9 cm. The results of the investigation reveal that the generator with the 0.15 mm variation in copper wire diameter performs better than the generators with the 0.75 mm variation in wire diameter. It can generate 80,6 watts of electric power, 1,231 N.m. of torque, 193,468 watts of mechanical force, and 41.66% of efficiency at a rotational speed of 1500 rpm. The result shows that the generator's performance will vary depending on the diameter of the wire at different rotating speeds.

Abstract

Concentrated Photovoltaic (CPV) technology offers the potential to enhance solar energy conversion by utilizing light focusing technology to increase the solar irradiation flux received by photovoltaic cells. On the other hand, as the solar energy density increases on a PV cell, the surface temperature of the PV also rises, which results in decreased energy conversion efficiency and the possibility of thermal fatigue. Therefore, a reliable cooling system is required for CPV. This study aims to evaluate the performance of a two-phase flow heat sink with ethyl acetate (C4H8O2) as the working fluid, which has a low boiling point and high heat of vaporization, making it quite effective for heat transfer. The method used is numerical simulation using Computational Fluid Dynamics (CFD) software. The simulation results show that the heat sink heat transfer effectiveness is 86.03%, with a thermal resistance value of 0.0073 . The highest temperature on the solid part is 105  showing an increasing trend but not significantly, while the average fluid temperature tends to remain constant at 55 . This indicates that the evaporation process is able to maintain the heatsink temperature at stable level.

Abstract

Alkali treatment using NaOH solution aims to to enhance the mechanical strength of the composite. This study investigates the effect of varying immersion durations of vetiver root fibers in a NaOH solution on the tensile strength of polyurethane-based composites. The vetiver fibers, serving as reinforcement, were cut to a length of 3 cm and immersed in a 5% NaOH solution for 2, 3, 4, and 5 hours, along with a control group without treatment. After soaking, the fibers were rinsed until reaching neutral pH and dried for three days. The composites were fabricated using the compression molding method under a pressure of 5 bar for 24 hours. Tensile tests were conducted following ASTM D638 standards. The results indicate that alkali treatment affected the surface characteristics of the fibers, including cleanliness and structural changes. The maximum tensile strength of 1.592 MPa was achieved with a 4-hour immersion, whereas the lowest tensile strength of 0.893 MPa was recorded after 5 hours of soaking.

Abstract

This study aims to develop a Sustainability Decision Support System (SDSS) based on the Sustainable Development Goals (SDGs) using a System Engineering approach at the Institut Teknolgi Bisnis dan Bahasa 'Dian Cipta Cendikia' (ITBA DCC). The main issues faced are a lack of a structured system to integrate environmental, social, economic, and governance aspects into policy campus. The methodology study covers six phases: Main, which includes Requirements Analysis, System Design, Implementation, Testing, Deployment, and Maintenance. This system merges Multi-Criteria Decision Making (MCDM) techniques, modeling system dynamics, and data analytics to visualize SDGs progress, prioritize programs, and provide recommendation strategies. Research results show that SDSS is capable of increasing transparency, accountability, and effectiveness in data-driven decision-making. The novelty of the study lies in its multidisciplinary and contextual approach to college-level vocational education in Indonesia. This system also has the potential to be replicated in other institutions as an innovative model for management sustainability

Abstract

Climate change and global sustainability demands are prompting universities to integrate sustainable principles into all academic and non-academic activities. This research led to the design and implementation of a Sustainability Decision Support System (SDSS) at Institut Teknologi Bisnis dan Bahasa Dian Cipta Cendikia (ITBA-DCC), using the System Engineering Process (SEP) and the Higher Education Sustainability Initiative (HESI) framework. The SDSS uses Multi-Criteria Decision Making (MCDM) and interactive data visualization to assess sustainability across four dimensions: environmental, social, economic, and governance. Initial pilot testing showed an overall sustainability index of 74/100, with the highest score in the environmental dimension (82/100) and the lowest in governance (68/100). User Acceptance Testing (UAT) reported a 91% satisfaction rate among staff, lecturers, and campus leaders. Although the system relies on annual data and some manual inputs, the SDSS shows potential for adoption by similar institutions and supports Sustainable Development Goals (SDGs) in higher education.
