Abstract

Microbubble Generator (MBG) merupakan sebuah alat yang mampu menghasilkan gelembung-gelembung berukuran mikro telah menjadi terobosan terkini dalam bidang aerasi karena memiliki banyak kelebihan dibandingkan dengan alat aerasi konvensional. Pada penelitian ini dikembangkan microbubble generator tipe aliran swirl dengan diameter outlet 30 mm, diameter nozzle gas 1,2 mm, dan jarak nozzle gas ke outlet sebesar 5 mm. Penelitian dilakukan untuk mengetahui karakteristik distribusi bubble dan performa microbubble generator dengan memvariasikan debit udara (QG) dan debit air (QL). Untuk mengetahui distribusi bubble digunakan high-speed camera melalui pengambilan gambar bubble yang diolah menggunakan teknik image processing. Digunakan pressure transducer untuk merekam tekanan yang terjadi pada inlet dan outlet MBG untuk mengetahui performa MBG melalui parameter hydraulic power (Lw) dan efisiensi hidrolis (ηh). Hasil penelitian menunjukkan dari analisis probability density function (PDF), ukuran bubble yang diperoleh berada pada rentang 100-200 μm. Nilai hydraulic power dan efisiensi hidrolis secara signifikan dipengaruhi oleh variasi debit air (QL) dibandingkan dengan variasi debit udara (QG). Dari hasil analisis wavelet teridentifikasi bahwa terjadi breakup dan coalescene bubble di setiap aliran air dan udara. Hasil dari penelitian diharapkan menjadi bahan pertimbangan dalam memilih dan merancang microbubble generator tipe aliran swirl.

Abstract

Dalam upaya mengurangi ketergantungan terhadap sumber energi berbasis fosil dan peningkatan penggunaan energi bersih, PLTS menjadi salah satu pilihan yang perlu dipertimbangkan. Optimalisasi penggunaan panel surya atap menjadi salah satu upaya penting dalam mendukung penerapan energi terbarukan. Penelitian ini menggunakan metode simulasi dengan perangkat lunak PV*Sol untuk menganalisis pengaruh arah hadap rumah terhadap produksi energi listrik. Studi dilakukan pada rumah tipe 36 meter persegi dengan arah hadap divariasikan dari utara dan diubah sebesar 10 derajat searah jarum jam hingga mencapai rotasi 180 derajat. Simulasi dilakukan menggunakan panel surya dengan kapasitas sebanyak 315 Wp sebanyak 16 buah dan dua buah inverter dengan kapasitas total 5,04 kWp. Hasil simulasi menunjukkan bahwa arah hadap rumah memiliki pengaruh signifikan terhadap produksi energi panel surya. Energi maksimum tercatat pada rumah yang menghadap ke timur, menghasilkan total produksi sebesar 7.245 kWp per tahun. Sebaliknya, energi minimum terjadi ketika rumah menghadap ke utara, dengan produksi hanya sebesar 7.159 kWp per tahun. Perbedaan ini disebabkan oleh perubahan sudut penerimaan cahaya matahari terhadap permukaan panel ketika matahari terbit dan terbenam, yang memengaruhi efisiensi penyerapan energi. Penelitian ini menunjukkan pentingnya perencanaan orientasi bangunan dalam desain sistem energi terbarukan berbasis panel surya. Studi ini memberikan rekomendasi praktis bagi perancangan sistem panel surya atap untuk memaksimalkan efisiensi produksi energi listrik, khususnya di wilayah tropis. Dengan optimalisasi arah hadap, penggunaan panel surya dapat lebih mendukung upaya transisi energi yang berkelanjutan.

Abstract

Currently, there are individuals around us living with disabilities caused by accidents or other factors. People with disabilities generally require assistance from others, particularly for mobility or moving from one place to another. Although manual wheelchairs can provide a solution for mobility, they remain challenging to operate using hand power alone and often require external help for movement. To facilitate mobility for individuals with disabilities, especially wheelchair users, an electric drive system in the form of an electric motor is proposed as a solution. The development of a motorized electric wheelchair aims to enhance the mobility of individuals with physical disabilities. Members of the Indonesian Association of Persons with Disabilities (PPID) were selected as community service partners for this initiative. It is hoped that, in addition to supporting mobility, the electric wheelchair can also serve as a body support system, enabling users to continue engaging in productive activities while seated.  The implementation of this program began with interviews conducted with persons with disabilities and related partners to understand their needs, followed by the design, fabrication, and subsequent socialization and training on the use of the electric wheelchair for the target beneficiaries. The outcome of this effort is an electric wheelchair equipped with joystick controls. The wheelchair employs a rear-wheel drive system powered by two motors, each attached to a rear wheel, and a chain transmission system. Along with delivering the electric wheelchair to the PPID, this initiative aims to serve as a practical application of mechanical engineering knowledge, directly benefiting the community..

Abstract

Pemesinan merupakan proses krusial dalam industri manufaktur untuk menghasilkan komponen presisi, di mana morfologi chip yang terbentuk dari pemesinan bubut berperan penting terhadap efisiensi proses dan kualitas produk akhir. Penelitian ini bertujuan untuk menganalisis pengaruh kecepatan spindle dan kecepatan eretan terhadap morfologi chip, khususnya panjang dan diameter chip, dalam proses pemesinan bubut. Desain eksperimen faktorial 2x2 digunakan, dengan dua faktor utama: kecepatan spindle (755 RPM dan 1255 RPM) serta kecepatan eretan (0,1160 mm/rev dan 0,2320 mm/rev). Analisis data dilakukan menggunakan ANOVA dua arah untuk menguji pengaruh masing-masing faktor dan interaksinya terhadap panjang dan diameter chip. Hasil penelitian menunjukkan bahwa baik kecepatan spindle maupun kecepatan eretan tidak memberikan pengaruh yang signifikan terhadap panjang maupun diameter chip (p-value > 0,05). Interaksi antara kedua faktor tersebut juga tidak menunjukkan pengaruh signifikan. Hal ini dapat disebabkan oleh rentang pengaturan kecepatan yang terbatas, serta pengaruh faktor lain seperti material dan kondisi pemotongan. Temuan ini memberikan wawasan bagi praktisi manufaktur dalam mengoptimalkan parameter pemesinan untuk meningkatkan kualitas produk akhir dan efisiensi proses.

Abstract

Permasalahan utama dalam budidaya perikanan air tawar adalah ketidakstabilan kualitas air yang sering tidak terdeteksi secara dini, terutama terkait parameter pH, Total Dissolved Solids (TDS), dan Dissolved Oxygen (DO). Pemantauan secara manual memerlukan waktu, tenaga, dan berisiko terhadap keterlambatan deteksi perubahan kualitas air yang berdampak pada penurunan produktivitas dan kesehatan ikan. Untuk menjawab tantangan ini, penelitian ini mengembangkan sistem monitoring kualitas air berbasis Internet of Things (IoT) menggunakan ESP32 Devkit V1 yang mengintegrasikan sensor pH, TDS, dan DO. Data ditampilkan secara lokal melalui LCD 20x4 I2C serta dikirim secara real-time ke platform Blynk dan Google Spreadsheet, guna memudahkan pemantauan jarak jauh dan pencatatan otomatis. Pengujian dilakukan pada akuarium yang dilengkapi teknologi mikrobubble untuk menganalisis efektivitas sistem dalam mendeteksi perubahan kualitas air. Hasil menunjukkan bahwa sensor pH dan TDS memiliki kinerja yang stabil dengan rata-rata pH 7,79 (±0,41) dan TDS 28,27 ppm (±6,97), sedangkan sensor DO menunjukkan nilai rendah (rata-rata 0,038 mg/L) dengan tren peningkatan saat penggunaan mikrobubble. Sistem ini terbukti mampu memberikan solusi pemantauan kualitas air yang efisien, akurat, dan real-time, serta berpotensi mendukung pengelolaan akuakultur berkelanjutan dengan pengembangan lebih lanjut pada sistem aerasi dan sensor DO.

Abstract

This study aims to design a walker for the elderly equipped with an adjustable height feature to improve user comfort and safety. The frame design was developed using CAD software and its structural strength was analyzed using the Finite Element Method (FEM). Simulations were carried out with static load variations ranging from 40 kg to 90 kg on aluminum alloy 6061-T4 material. The analyzed parameters include von Mises stress, equivalent strain, total deformation, and safety factor. The simulation results show a maximum von Mises stress of 28.99 MPa at a 90 kg load, which remains well below the material’s yield strength of 230 MPa, with a minimum safety factor of 7.849. These findings demonstrate that the walker design is safe to use within the tested load range. Future research is recommended to conduct dynamic structural testing and experimental validation of the physical prototype.

Abstract

Mountain bikes have become a popular mode of transportation and recreation among extreme sports enthusiasts. A strong and lightweight frame design is crucial to support performance and ensure rider safety, especially in challenging terrain conditions. This study aims to explore the optimization of mountain bike frame design with a focus on the use of high-strength carbon materials. The research evaluates the performance and durability of the frame through Von Mises stress analysis, displacement, and safety factor under load variations of 65 kg, 70 kg, and 75 kg. The analysis results show that the stress increases with the load, from 7.298 MPa at 65 kg to 8.421 MPa at 75 kg. Displacement also increases, from 0.004982 mm to 0.005748 mm. The safety factor remains above 15, indicating a high safety margin for the material. These findings suggest that although stress and deformation increase, the frame design still meets the strength standards required for user safety. This research contributes significantly to the development of more efficient, sustainable bicycles, and serves as a reference for manufacturers in designing safe and comfortable products. Recommendations for further testing include dynamic load analysis to understand the frame's behavior under real-world usage conditions. Keywords: AL 6061, Mountain Bike Frame, Simulation
