Abstract

Kebutuhan energi yang terus meningkat diiringi pertumbuhan populasi dan ekonomi global mendorong pencarian solusi alternatif. Blueprint Pengelolaan Energi Nasional 2006-2025 Indonesia menetapkan target energi untuk tahun 2025, termasuk peningkatan penggunaan batu bara dan energi terbarukan. Limbah tempurung kelapa dan cangkang kemiri, yang masih belum optimal dimanfaatkan, menjadi fokus penelitian ini untuk digunakan sebagai bahan bakar alternatif dalam bentuk briket. Penelitian sebelumnya menunjukkan berbagai cara efisien untuk memanfaatkan kedua limbah tersebut. Modifikasi kompor briket dengan tempurung kelapa menghasilkan briket dengan nilai kalor tinggi, sementara briket cangkang kemiri dapat mengurangi polusi dan meningkatkan efisiensi termal. Penelitian ini mencoba mencampur kedua limbah ini dengan berbagai komposisi untuk mengevaluasi efektivitasnya sebagai pengganti minyak tanah yang semakin langka. Penggunaan tempurung kelapa dalam briket umum, namun, dapat menjadi mahal. Oleh karena itu, solusi yang diajukan adalah menambahkan limbah pertanian, seperti cangkang kemiri, untuk mengurangi biaya produksi tanpa mengorbankan kualitas briket. Penelitian ini membandingkan berbagai komposisi briket, termasuk CK50% + TK50%, CK40% + TK60%, CK60% + TK40%, CK30% + TK70%, CK70% + TK30%, CK20% + TK80%, dan CK80% + TK20%. Parameter yang diuji melibatkan kadar air, kadar abu, waktu pembakaran, dan shutter index. Hasil penelitian menunjukkan bahwa komposisi CK60% + TK40% dan CK20% + TK80% menunjukkan performa terbaik. Keduanya memberikan briket dengan daya tahan tinggi, stabilitas, dan efisiensi waktu pembakaran optimal. Kombinasi CK30% + TK70% dan CK20% + TK80% menunjukkan kadar air dan kadar abu stabil, sementara CK50% + TK50%, CK20% + TK80%, dan CK30% + TK70% menunjukkan waktu pembakaran yang lebih lama. Shutter index pada CK60% + TK40% dan CK20% + TK80% menunjukkan daya tahan yang kuat.

Abstract

Hydroponics is an agricultural system that requires electricity to drive water pumps that flow irrigation, and solar panels are tools to convert solar energy into electrical energy. The drawback of installing solar panels so far is static so that the power received is not optimal, considering that the sun is always moving around the earth. In this case a solar panel with a solar tracker system is used as a source of electrical energy for the water pump. The purpose of using a solar tracker on this hydroponic solar panel is to optimize the absorption of the energy received by the solar panel. The method used in this research is the method of literature study and experimental research. The research was conducted from March 4 - April 15 2023 from 07.00 - 18.00 WIB with 1 day of static position testing each, and 1 day of solar tracker solar panels every day. The total power obtained during the test was 2823.31W on the solar tracker system after deducting the power consumption of the solar tracker system, while in a static position the power obtained was 1843.71W. On the solar tracker system it takes 3 Hours 54 Minutes to charge the battery after the battery power is used for 13 hours. Meanwhile, in a static position it takes 6 hours. The conclusion from this study is that the solar panel solar tracker system in hydroponics is capable of producing a power increase of 53% compared to hydroponic solar panels in a static position.

Abstract

Semakin berkurangnya jumlah bahan bakar fosil yang tersedia telah mendorong kebutuhan akan sumber energi alternatif dan terbarukan. Oleh karena itu, pencarian untuk menemukan sumber bahan alternatif yang dapat diperbarui, ekonomis, dan ramah lingkungan menjadi suatu kegiatan yang sangat penting untuk pengembangan sumber energi yang lebih berkelanjutan. Salah satu solusinya adalah melalui penggunaan Biobriket, yaitu briket atau arang yang dihasilkan dari limbah biomassa seperti dedaunan, ranting, jerami, kayu, dan berbagai jenis bahan hayati lainnya. Pembuatan Biobriket dipengaruhi oleh beberapa faktor, termasuk bahan yang digunakan, kehalusan arang hasil karbonisasi, massa jenis arang, temperatur karbonisasi, variasi komposisi, dan tekanan pada proses pencetakan. Biobriket ini memiliki keunggulan dalam menghasilkan asap yang sangat sedikit, bahkan hanya timbul saat proses penyalaan. Pada penelitian ini, biobriket dibuat sedemikian rupa dengan menggunakan campuran tempurung kelapa dan kayu rambutan dengan komposisi yang berbeda-beda. Dua perekat digunakan pada penelitian ini, yaitu molase dan tepung kanji. Hasil penelitian menunjukkan bahwa campuran briket dengan kualitas terbaik adalah briket dengan komposisi campuran 90% arang dan 10% perekat (molase dan pati kanji). Hal ini disimpulkan dari beberapa faktor pengujian yaitu, densitas, shutter index, laju pembakaran, dan sisa abu. Penelitian ini telah berhasil memberikan wawasan mengenai pembuatan biobriket dengan menggunakan bahan baku tempurung kelapa dan kayu rambutan berperekat molase dan tepung kanji.

Abstract

Piezoelectric energy harvesters (PEHs) are gaining attention for their ability to generate electrical energy from environmental vibrations, with applications in various industries. This study focuses on optimizing the performance of a PEH using a cantilever system driven by wind energy through the impact of windmill blades. The objective is to evaluate how the number of windmill blades affects the PEH's voltage output and vibration stability. Experiments were conducted in a wind tunnel with a 250 mm × 250 mm cross-section equipped with a 12-inch blower to generate airflow. Three windmill configurations—3 blades, 4 blades, and 5 blades—were analyzed for output voltage and deflection of two PVDF-based PEHs placed at a 30° angle. Results indicate that the 3-blade configuration produced the highest voltage (1.79V), 4% and 43% higher than the 4-blade (1.71V) and 5-blade (1.01V) configurations, respectively. This configuration also exhibited maximum deflection and lower frequency vibrations. Increasing blade count led to higher frequency vibrations but reduced deflection and voltage output. The study highlights that fewer blades result in greater deflection and better energy harvesting performance. These findings contribute to ongoing research in PEH systems, offering insights into optimizing energy harvesting from fluctuating wind conditions by balancing deflection amplitude and vibration frequency.

Abstract

Plastic injection (injection molding) is a method of forming products from plastic pellets into various daily necessities products. In terms of supporting daily needs, plastic injection molded products must meet criteria, such as strength, ductility, flexibility, hardness, etc. One of the easiest ways is to do a tensile test. In this research, mold with the shape of tensile test specimen products was carried out through several process stages, namely design and simulation, fabrication, and product testing. Autodesk Fusion 360 software is used in the design process to simulate and predict material flow during the injection process into the mold with several parameter variations in the form of time, material temperature and mold temperature. The results obtained were by using polypropylene (PP) plastic material, the maximum injection conditions were by suing a melting temperature of 230°C and a mold temperature of 50°C with an injection time of 14.5 seconds, where it was predicted that the product would be easy to fill and the resulting quality would reach 100% good. This research has succeeded in designing and predicting a plastic injection process that can be utilized in the plastic molding process through the actual injection process in industries that use polypropylene material.

Abstract

Button fatigue testing remains prohibitively expensive for SMEs due to commercial systems costing >$5,000. This study develops a low-cost tester of less than $500, PLC-controlled using dual actuation systems (pneumatic and DC motor) to evaluate pushbutton durability under 100–300 g loads. The pneumatic system maintained extensive pressure stability of ±0.00 MPa at 0.04 MPa for 200 g testing but exhibited 20.64% load deviation due to compressor-induced 600 g transient spikes during reservoir refills. Alternatively, the DC motor system achieved high-precision 100 g testing at 270 rpm with 3.98% deviation with stable speed around 260–278 rpm but failed operationally at 540 rpm for 300 g loads due to vibration-induced signal disruption after cycle 277. Moreover, pneumatic actuation proved more suitable for loads lower than 200 g, completing 10,000 cycles despite load spikes, while a DC motor maintains stability at lower than 200 g with near-constant force below 500 rpm. This study establishes a clear implementation framework: pneumatic systems for production-line screening where ±20% deviation is acceptable per ISO 9241-410 and DC motor systems for calibration-grade testing requiring <5% deviation. The prototype bridges the affordability gap for SMEs and educational institutions, with future work targeting vibration dampeners and pressure accumulators to achieve ASTM E467-21 compliance.

Abstract

Solar panel-based electric charging stations are a combination of electricity sources and solar panels, allowing efficient and effective charging and helping to source electricity from natural energy in the form of renewable energy, namely the sun. The use of solar panels as the main energy source can reduce dependence on limited energy sources and produce lower greenhouse gas emissions and reduce dependence on fossil energy sources. The purpose of this thesis is to design and analyze the strength and durability of solar panel-based electric charging stations on their supports. The method used in this study is quantitative data taken using Ansys software simulations. The results showed that Design 1 on the solar panel supports had a maximum deformation of 0.2397 mm at an angle of 70 and design 2 produced a maximum deformation of 0.0052439 mm at an angle of 70 to the right/left. Based on these results, it can be concluded that the design of 1 solar panel support is better in terms of strength and durability because the load on the solar panel that is on the support only has an effect of 0.2397 mm which can withstand a load of around 320 N.

Abstract

The use of solar panels in electric power charging stations is becoming increasingly popular as part of efforts to adopt renewable energy sources. In this context, the structural framework supporting the solar panels plays a crucial role in maintaining the stability and reliability of the system. Therefore, this thesis aims to investigate the influence of various structural framework variations on the strength of static loading in solar-powered electric charging stations. The research methodology employed simulation of static loading at three different load levels, namely 40 kg, 50 kg, and 60 kg. The analysis was conducted by comparing the equivalent stresses and total deformations between "Design 1" and "Design 2" at each load level. The research findings reveal significant differences in equivalent stresses and total deformations between the two designs at each load level. Design 1, with a stiffer structural framework, exhibited higher equivalent stresses and greater total deformations compared to Design 2. Consequently, this study provides a deeper understanding of the influence of various structural framework variations on the strength of static loading in solar panel support structures. These findings can serve as a basis for optimizing the structural design of solar-powered electric charging systems.

Abstract

High wind velocity can induce external pressures and loads on the structural framework of an Electric Vehicle Charging Station (EVCS), jeopardizing the overall stability and structural integrity of the framework. The objective of this research is to ascertain the magnitude of aerodynamic drag force and the maximum pressure values on the surface of the EVCS framework, with respect to variations in wind velocity. The methodology employed in this study involves Computational Fluid Dynamics (CFD) simulations utilizing the Solidworks Flow Simulation. Three wind velocity scenarios were considered: 3 km/h, 6 km/h, and 9 km/h, allowing for the observation of airflow acceleration phenomena, aerodynamic drag force values, and peak pressure distributions on the EVCS framework's surface. Research findings reveal that the aerodynamic drag force at a wind velocity of 3 km/h measures 22,34 N, escalating to 90,42 N at 6 km/h wind velocity, and reaching 202,7 N at 9 km/h wind velocity. Furthermore, the highest-pressure value at a wind velocity of 3 km/h is 101325,45 Pa. As the wind velocity increases to 6 km/h, the maximum pressure value rises to 101338,18 Pa. Under the condition of the highest input wind velocity, i.e., 9 km/h, the peak pressure reaches 101353,46 Pa.
