Abstract

This research aims to assess the potential of bio-oil from Moringa oleifera seeds through the analysis of physical and chemical characteristics resulting from the pyrolysis process. Raw materials in the form of Moringa oleifera seed powder were pyrolyzed at 400°C using a microwave reactor. To create oxygen free pyrolysis conditions, nitrogen gas was constantly flowed into the system at a rate of 0.15 NL/min. The process temperature was monitored using a K-type thermocouple, and the reaction was stopped when condensed vapor output was no longer observed. The pyrolysis products in the form of bio-oil and bio-char were then collected and weighed to determine the product fraction. Furthermore, the bio-oil was analyzed to determine its physical and chemical properties, including density, pH, and an indication of its constituent compound components. The results showed that pyrolysis under these conditions produced a dominant amount of bio-char (54.3%) and bio-oil of 24.7% of the total weight. The bio-oil obtained had a high density, in the range of 0.97-1.00 g/cm³, with a relatively acidic pH of 4.5-5.5. Although the bio-oil yield is not high, its complex chemical properties, particularly the content of phenolic compounds, nitriles, and amides, show great potential to be developed as a valuable bio-chemical base material such as antioxidants, biophenols, resins, and bioplastic raw materials. These findings strengthen the prospect of Moringa oleifera seeds as a strategic local biomass for sustainable bioindustry.

Abstract

This study aims to assess the potential of bio-char derived from Moringa oleifera seeds through an evaluation of its physical and chemical properties. Moringa oleifera seeds were processed into fine powder, dried, and then subjected to pyrolysis at 400°C using a microwave reactor. Nitrogen gas was introduced before and during the pyrolysis process to create a low-oxygen environment. The pyrolysis continued until no more condensable vapors were detected, indicating that the thermal decomposition process had reached completion. The resulting bio-char was collected and analyzed to determine its physical and chemical characteristics, including proximate analysis (moisture content, ash content, volatile matter, and fixed carbon), calorific value, and density. The results showed that the bio-char from Moringa oleifera seed powder had a very high fixed carbon content of 79.13% and low volatile matter. The calorific value reached 25.04 MJ/kg, which is comparable to that of low-rank coal. Additionally, the bio-char had a density of 0.905 g/cm³, which is relatively high compared to most biomass-derived bio-chars. These characteristics indicate that bio-char from Moringa oleifera seeds holds significant potential for use as a solid fuel in the form of briquettes or pellets, as a biomass energy source, and as a long-term carbon storage medium for climate change mitigation.

Abstract

A crucial global issue is the world's dependence on fossil fuels as its primary energy source. An alternative solution to this problem is to use fuels such as ethanol. Using ethanol as fuel requires comprehensive optimization of the vehicle system, including the engine's temperature control. This research aims to determine the effect of engine operating temperature variations on fuel efficiency thru 4 engine temperature variations: 70, 80, 90, and 100 degrees Celsius, using two approaches: static and dynamic. The test results show that engine temperature affects fuel consumption and engine operating stability. Based on the experiments conducted, it was concluded that a temperature of 90°C is the most optimal working temperature, with an increase of 9.91% in static testing and 14.74% in dynamic testing (compared to the temperature with the lowest efficiency). It can be concluded that 90°C is recommended as the optimal working temperature for ethanol engines in the development of energy-efficient vehicles.

Abstract

Penelitian ini bertujuan untuk menganalisis hubungan antara laju aliran fluida terhadap parameter perpindahan panas dan penurunan tekanan pada sistem pipa heliks. Metode eksperimen dilakukan dengan pengamatan 23 titik waktu dalam satuan detik, menggunakan alat sensor suhu dan tekanan. Hasil menunjukkan bahwa Nilai 1 meningkat dari 12,47 hingga 87,33, sedangkan Nilai 2 mencapai puncaknya di 100 sebelum mengalami penurunan. Penurunan tekanan dihitung sebesar 6 psi menggunakan persamaan Darcy–Weisbach. Data grafik menunjukkan adanya zona linier dan zona jenuh, mencerminkan keterbatasan respons sistem sensor saat beban termal meningkat. Temuan ini menunjukkan bahwa hubungan input-output tidak selalu linear dan sistem memiliki batas performa tertentu yang perlu dikendalikan

Abstract

Pertumbuhan jumlah penduduk di Indonesia yang terus meningkat berdampak pada semakin menipisnya ketersediaan bahan bakar fosil. Seiring dengan kondisi tersebut, pengembangan sumber energi alternatif pun semakin berkembang, salah satunya adalah briket biomassa. Briket biomassa merupakan salah satu bentuk energi terbarukan yang dapat dimanfaatkan sebagai pengganti bahan bakar minyak. Namun demikian, proses produksi briket biomassa umumnya masih dilakukan secara manual karena penelitian dan pengembangan terhadap alat pemotong briket otomatis masih terbatas. Beberapa studi sebelumnya telah merancang alat pemotong briket otomatis berbasis mikrokontroler Arduino  dengan tingkat konsistensi sebesar 77,5% hingga 90,7%. Penelitian ini bertujuan untuk menganalisis kinerja serta mengembangkan alat pemotong briket otomatis berbasis sistem pneumatika dengan variasi kadar air pada adonan briket sebagai variabel. Parameter yang dikaji meliputi tingkat konsistensi dan produktivitas alat pemotong briket otomatis tersebut. Hasil pengujian menunjukkan bahwa konsistensi tertinggi sebesar 91,6% dan produktivitas sebesar 68,1% diperoleh pada pengujian ketiga dengan kadar air adonan sebesar 46,9%. Kinerja alat ini masih dapat ditingkatkan melalui penyesuaian kecepatan pada mesin screw extruder, modifikasi pada bidang miring tempat jatuhnya briket, serta optimalisasi bahan campuran adonan briket.

Abstract

Krisis energi akibat menurunnya ketersediaan bahan bakar fosil mendorong pengembangan kendaraan hemat energi, salah satunya melalui upaya pengurangan rolling resistance pada ban kendaraan Urate Evo-7. Penelitian ini bertujuan untuk menganalisis pengaruh variasi tekanan ban terhadap waktu akselerasi, jarak gelincir, dan efisiensi konsumsi bahan bakar. Metode penelitian yang digunakan adalah eksperimental dengan variasi tekanan ban sebesar 55 psi, 65 psi, 75 psi, dan 85 psi. Pengujian dilakukan di Sirkuit Mijen Semarang sepanjang 2,7 km dengan empat kali percobaan pada setiap variasi tekanan ban. Parameter yang diamati meliputi waktu tempuh satu lap, jarak gelincir kendaraan dari kecepatan 32 km/jam hingga berhenti tanpa pengereman, serta konsumsi bahan bakar yang diukur menggunakan buret, stopwatch dan pita ukur, kemudian dianalisi secara deskriptif dan komparatif. Tekanan ban 85 psi menghasilkan jarak gelincir rata-rata sepanjang 778 meter dan konsumsi bahan bakar rata-rata  18 ml dengan efisiensi mencapai 450 km/l. Kendaraan Pandawa Team dapat meningkat sebesar 34,5% dibandingkan tekanan ban 55Psi. Diikuti pengurangan waktu saat berakselerasi sebesar 10,6 % dan jarak gelincir saat mesin dimatikan mengalami peningkatan 17,5%. Secara keseluruhan, hal ini didasari perbedaan tekanan ban pada kendaraan, sehingga nilai rolling resistance menurun akibat dari tekanan ban yang lebih besar. Penelitian ini diharapkan dapat menjadi referensi dalam pengembangan kendaraan hemat energi berbasis optimasi tekanan ban.

Abstract

This review paper provides an overview of simulation-based hydrodynamic design optimization for ship hull forms. It also includes a numerical analysis aimed at accomplish early-stage simulation-based design in terms of hydrodynamic performance. A hydrodynamic module, a hull surface modeling module, and an optimization module are the primary components of this numerical analysis. The hydrodynamic module includes both simple design approaches and high-fidelity numeric tools; these integrated tools are used to evaluate hydrodynamic performances at different design stages. The hull surface modeling module offers a variety of techniques for ship hull surface representation and modification. It is also used to automatically create hull forms or change existing hull forms based on hydrodynamic performance and design constraints. The optimization module includes several optimization algorithms and surrogate models used to determine optimal designs in terms of hydrodynamic performance. Numerical findings indicate that the current tool is well suited for hull form design optimization at the early design stage because it can produce effective optimal designs within a short time.
