Abstract

Limbah kulit singkong dan kulit pisang berpotensi menjadi bahan baku bioetanol dan mendukung pengolahan limbah organik. Penelitian ini bertujuan membandingkan karakteristik nyala api bioetanol dari kedua limbah tersebut melalui hidrolisis, fermentasi, dan distilasi. Penelitian menggunakan ragi Farmipan sebagai sumber Saccharomyces cerevisiae dengan variasi massa 4 g dan 8 g, serta volume bahan bakar 1 mL, 2 mL, dan 3 mL. Parameter yang diamati meliputi kadar gula terlarut, tinggi, luas, dan durasi nyala api. Kulit singkong menghasilkan kadar gula terlarut 66°Brix, sedangkan kulit pisang 16°Brix. Bioetanol kulit pisang 8 g menghasilkan tinggi nyala tertinggi pada seluruh volume. Luas nyala tertinggi diperoleh pada kulit pisang 8 g untuk 1 mL dan kulit singkong 8 g untuk 2–3 mL. Durasi terlama diperoleh pada kulit pisang 4 g untuk 1–2 mL dan kulit singkong 4 g untuk 3 mL. Temuan ini merupakan data awal karena kadar etanol, nilai kalor, rendemen, dan emisi belum diukur. Cassava peel and banana peel wastes have potential as bioethanol feedstocks. This study compared the flame characteristics of bioethanol from these wastes through hydrolysis, fermentation, and distillation. The experiment used Farmipan yeast containing Saccharomyces cerevisiae at 4 g and 8 g, with fuel volumes of 1 mL, 2 mL, and 3 mL. The observed parameters were soluble sugar, flame height, flame area, and flame duration. Cassava peel produced 66°Brix soluble sugar, whereas banana peel produced 16°Brix. Banana peel bioethanol with 8 g yeast produced the highest flame height at all volumes. The highest flame area was obtained from banana peel 8 g at 1 mL and cassava peel 8 g at 2–3 mL. The longest duration was obtained from banana peel 4 g at 1–2 mL and cassava peel 4 g at 3 mL. These findings are preliminary because ethanol content, calorific value, yield, and emissions were not measured.

Abstract

Penelitian ini bertujuan menganalisis penggunaan campuran Pertamax dengan bioetanol dari ampas tebu dan kulit nanas terhadap emisi gas buang Honda Beat 2025 sistem injeksi. Penelitian menggunakan metode eksperimen dengan lima variasi bahan bakar, yaitu Pertamax murni (B0), E5 tebu, E10 tebu, E5 nanas, dan E10 nanas. Pengujian dilakukan pada 1500, 2500, 4000, 5500, dan 7000 rpm dengan tiga pengulangan. Parameter yang diamati meliputi CO, CO₂, HC, O₂, lambda, dan AFR menggunakan gas analyzer dan scan tool. Hasil menunjukkan bahwa campuran bioetanol menurunkan rata-rata CO dan HC dibandingkan Pertamax murni. Nilai CO terendah diperoleh pada E10 tebu sebesar 0,410%, sedangkan HC terendah diperoleh pada E10 nanas sebesar 96,20 ppm. Secara deskriptif, E10 tebu menunjukkan penurunan CO paling menonjol, sedangkan E10 nanas menunjukkan penurunan HC paling menonjol dibandingkan variasi bahan bakar lainnya. Temuan ini mengindikasikan bahwa bioetanol limbah tebu dan limbah nanas berpotensi sebagai campuran Pertamax untuk mendukung pembakaran yang lebih bersih pada motor injeksi. This study analyzed Pertamax blended with bioethanol from sugarcane bagasse and pineapple peel on exhaust emissions of a 2025 fuel-injected Honda Beat motorcycle. An experimental method was applied using five fuel variations: pure Pertamax (B0), E5 sugarcane, E10 sugarcane, E5 pineapple, and E10 pineapple. Tests were conducted at 1500, 2500, 4000, 5500, and 7000 rpm with three repetitions. The observed parameters included CO, CO₂, HC, O₂, lambda, and AFR, measured using a gas analyzer and scan tool. The results showed that bioethanol blends reduced average CO and HC compared with pure Pertamax. The lowest CO was obtained with E10 sugarcane at 0.410%, while the lowest HC was obtained with E10 pineapple at 96.20 ppm. Descriptively, E10 sugarcane showed the most prominent CO reduction, whereas E10 pineapple showed the most prominent HC reduction among the tested fuel variations. These findings indicate the potential of sugarcane and pineapple waste bioethanol as a Pertamax blend to support cleaner combustion in fuel-injected motorcycles.

Parameter CO, CO₂, O₂, HC, lambda, dan AFR diukur menggunakan gas analyzer. Data dianalisis melalui rata-rata dan persentase perubahan terhadap E0. Hasil menunjukkan seluruh campuran bioetanol menurunkan rata-rata CO dan HC dibandingkan E0. E10 pisang menjadi variasi paling menonjol secara deskriptif, dengan CO 0,410% dan HC 98,67 ppm, atau turun 40,92% dan 48,01%. Temuan ini mengindikasikan potensi awal bioetanol limbah kulit pisang sebagai campuran Pertamax untuk menurunkan CO dan HC pada rentang rpm yang diuji. This study compared exhaust emissions of a fuel-injected Honda BeAT operated with pure Pertamax and Pertamax blended with banana-peel and cassava-waste bioethanol. A descriptive quantitative experimental method was applied under no-load conditions after the engine reached operating temperature. Five fuel variations were tested: E0, E5 banana, E10 banana, E5 cassava, and E10 cassava. Tests were conducted at 1500, 3000, 4500, 6000, and 7500 rpm with five replications. CO, CO₂, O₂, HC, lambda, and AFR were measured using a gas analyzer. Data were analyzed using mean values and percentage changes relative to E0. All bioethanol blends reduced average CO and HC compared with E0. E10 banana was the most prominent variation descriptively, with CO of 0.410% and HC of 98.67 ppm, corresponding to reductions of 40.92% and 48.01%. These findings indicate the preliminary potential of banana-peel bioethanol as a Pertamax blend to reduce CO and HC.

Abstract

A novel approach was devised to optimize the stator slot semi-closed type in order improve the magnetic flux connection and minimize iron leakage in high-speed spindle drives. The concept was executed through a combination of response surface approach including the technique of finite element analysis. The primary objective of this investigation would be to provide an engineering approach which improves the functionality of stator criteria, including the stator slot geometry, coil turn per slot, and wire size. The purpose is to achieve higher flux connection and minimize iron leakage. This study presents an enhanced analytical approach that incorporates the analysis of stator flux connection, finite element calculation of flux connection, and iron leakage analysis of stator variables. The results are analyzed through the utilization of finite element computation, and their accuracy is verified through experimental measurements. The findings suggest the ideal design yields increased magnetic flux connection and reduced iron leakage in comparison to the industrial layout. The precision provided by the suggested model is confirmed through the comparison of the simulation and experimental information. In general, the percentage of errors is estimated to be around 7%.

Abstract

The Competency Test for Teacher Professional Education Program Participants (UKPPPG) is an essential stage for assessing the professionalism of vocational teachers, including those in the field of automotive engineering. Adequate preparation is required to ensure that teachers meet competency standards while also improving the quality of learning in vocational schools. This study aims to describe the preparation strategies facilitated by the Automotive Engineering Subject Teacher Forum (MGMP) in West Sumatra and to identify the challenges teachers face in preparing for the UKPPPG. This research employed a descriptive qualitative approach with a case study design. The subjects consisted of 15 automotive teachers who were actively involved in MGMP activities and preparing for the UKPPPG. Data were collected through in-depth interviews, participatory observation, and document analysis. Thematic analysis was carried out through coding, theme identification, and verification using source and method triangulation. The findings indicate that MGMP preparation strategies include lesson plan development, microteaching, and exam discussions. These activities improved teachers’ pedagogical skills; however, limitations such as inadequate workshop facilities, conventional teaching materials, and the lack of computer-based simulations hindered optimal preparation. This study concludes that MGMP plays a significant role in preparing teachers for the UKPPPG, although its effectiveness remains limited to pedagogical aspects. A more comprehensive strategy involving curriculum renewal, access to updated materials, psychological support, and digital technology integration is needed.

Abstract

Pemanfaatan energi getaran pada suspensi kendaraan merupakan salah satu strategi untuk mengurangi ketergantungan terhadap sumber energi fosil. Penelitian ini bertujuan mengoptimalkan pembangkitan energi listrik Electromagnetic Regenerative Shock absorber (ERSA) pada suspensi belakang Toyota Avanza menggunakan metode Taguchi. Tiga faktor diuji, yaitu jumlah lilitan kumparan (1500–2500 lilitan), diameter kawat (0,2–0,4 mm), dan air gap (2–6 mm) dengan orthogonal array L9 dan kriteria larger-the-better terhadap tegangan keluaran. Hasil analisis S/N dan ANOVA menunjukkan bahwa jumlah lilitan dan diameter kawat berkontribusi masing-masing 55,10% dan 38,96% terhadap variasi tegangan, sedangkan pengaruh air gap relatif kecil. Kombinasi optimum A3B3C3 (2500 lilitan, kawat 0,4 mm, air gap 6 mm) menghasilkan tegangan verifikasi 5,30 V dengan galat 5% terhadap prediksi model. Temuan ini mengindikasikan bahwa ERSA berpotensi dimanfaatkan sebagai sistem energy harvesting berdaya rendah bila dikombinasikan dengan rangkaian penyimpan dan pengkondisi daya. Harvesting vibration energy from vehicle suspensions is a strategy to reduce dependence on fossil-fuel electricity. This study aims to optimize the electrical output of an Electromagnetic Regenerative Shock absorber (ERSA) installed on the rear suspension of a Toyota Avanza using the Taguchi method. Three control factors were investigated number of coil turns (1500–2500 turns), wire diameter (0.2–0.4 mm), and air gap (2–6 mm) arranged in an L9 orthogonal array with a larger-the-better criterion for output voltage. Signal-to-noise and ANOVA analyses indicate that coil turns and wire diameter contribute 55.10% and 38.96% of the voltage variation, whereas the influence of air gap is small. The optimal combination A3B3C3 (2500 turns, 0.4-mm wire, 6-mm air gap) yields a verification voltage of 5.30 V with a 5% error relative to the predicted response. These findings show that ERSA has potential as a low-power automotive energy-harvesting system when combined with power-conditioning and storage circuits.

Abstract

Penggunaan sepeda motor di Indonesia terus meningkat, memicu dua masalah utama: keterbatasan bahan bakar fosil dan meningkatnya polusi udara. Penelitian sebelumnya banyak menyoroti dampak lingkungan, namun aspek ketahanan mesin belum dikaji secara mendalam. Penelitian ini bertujuan menganalisis pengaruh kombinasi busi platinum, pengapian +2°, biogasoline E25, dan sistem Water Injection berbasis ultrasonic mist maker terhadap durabilitas mesin sepeda motor empat langkah. Metode eksperimen dilakukan dengan membandingkan kondisi standar (pertalite) dan perlakuan kombinasi selama 110 jam operasional. Hasil penelitian menunjukkan penurunan signifikan massa deposit karbon dari 680 mg menjadi 260 mg serta volume dari 378 mm³ menjadi 144 mm³, atau pengurangan lebih dari 61%. Temuan ini membuktikan bahwa kombinasi biogasoline dan Water Injection tidak hanya mengurangi pembentukan deposit karbon, tetapi juga berpotensi memperpanjang usia pakai mesin serta mendukung teknologi transportasi ramah lingkungan. The rapid increase in motorcycle use in Indonesia has created two major challenges: fossil fuel depletion and rising air pollution. While previous studies mainly focused on environmental impacts, engine durability remains underexplored. This study aims to evaluate the effects of combining platinum spark plugs, +2° ignition timing, E25 biogasoline, and a Water Injection system using an ultrasonic mist maker on the durability of four-stroke motorcycle engines. An experimental method was conducted by comparing standard conditions (pertalite) with the combined treatment over 110 hours of operation. Results indicated a significant reduction in carbon deposits, with mass decreasing from 680 mg to 260 mg and volume from 378 mm³ to 144 mm³, representing a reduction of over 61%. These findings highlight that the integration of biogasoline and Water Injection not only reduces carbon deposit formation but also extends engine lifespan and supports environmentally friendly transportation technologies.

Abstract

Penelitian ini menganalisis kekuatan struktural rangka trainer sepeda listrik sebagai media pembelajaran di SMK. Rangka dirancang dari pipa baja dan dianalisis menggunakan simulasi Finite Element Analysis pada perangkat lunak SolidWorks 2021. Tiga material dibandingkan, yaitu Baja Chromoly SAE 4130, Aluminium 6061-T6, dan Hi-Ten Steel (AISI 1015). Pembebanan statis 120 kg diterapkan pada titik dudukan pengendara, dengan tumpuan tetap pada titik hubung rangka sehingga diperoleh distribusi tegangan von Mises, displacement, dan safety factor. Hasil simulasi menunjukkan bahwa Baja Chromoly SAE 4130 memiliki kombinasi tegangan, deformasi, dan faktor keamanan paling baik, sedangkan Aluminium 6061-T6 menghasilkan displacement terbesar dan Hi-Ten Steel memiliki margin keamanan terendah. Nilai Safety Factor Minimum seluruh material masih kurang dari satu, sehingga desain rangka perlu dioptimasi. Temuan ini menjadi dasar pemilihan material dan perbaikan desain rangka trainer sepeda listrik di lingkungan pendidikan vokasi untuk mendukung pembelajaran berbasis praktik rekayasa. This study analyzes the structural strength of an electric bicycle trainer frame used as an instructional medium in vocational high schools. The frame is constructed from steel pipes and evaluated through Finite Element Analysis simulation using SolidWorks 2021. Three materials are compared, namely Chromoly Steel SAE 4130, Aluminum 6061-T6, and Hi-Ten Steel (AISI 1015). A static load of 120 kg is applied at the rider’s seat with fixed supports at frame joints to obtain the distribution of Von Mises Stress, displacement, and safety factor. The results indicate that Chromoly Steel SAE 4130 provides the most favorable combination of Stress, deformation, and structural safety, while Aluminum 6061-T6 exhibits the largest displacement and Hi-Ten Steel the lowest safety margin. The minimum safety factor of all materials is still below one, so the frame design requires optimization. These findings guide material selection and frame redesign for engineering practice–oriented vocational education.

Abstract

Brushless Direct Current (BLDC) motors are increasingly utilized across various applications due to their high efficiency and reliability. However, their control requires precise handling, especially during the commutation process. This study presents a detailed simulation design for BLDC motor control using MATLAB Simulink, focusing on the Six-Step Commutation method and PID-based speed regulation. The methodology involves constructing an open-loop model to analyze commutation behavior, followed by a closed-loop system using PID controllers with automatic parameter tuning. The simulation demonstrates accurate replication of hall sensor signals, back-EMF waveforms, switching patterns, and motor responses. Results reveal that the PID controller effectively maintains target speed across varying reference inputs and load conditions, while phase current and electromagnetic torque increase proportionally with speed and load. Results confirm correct switching in open loop and show that, in closed loop, the controller maintains speed within ±2% of the target with brief, well-damped transients. Phase current and torque responses scale with speed and load, informing practical refinements (anti-windup, ripple mitigation, soft-commutation timing). The findings certify that simulation is a vital step to ensure functional logic and hardware readiness, minimizing risks and enhancing system performance prior to physical implementation.

Abstract

This study aimed to develop a web-based electronic jobsheet system for the periodic motorcycle service subject at SMK Negeri 4 Palembang using the ADDIE model. The development was motivated by the continued use of paper-based practical assessment, which limits documentation and digital integration in vocational learning. The system integrates learning materials, digital jobsheets, procedural checklists, evidence uploads, and assessment features within a platform. The study employed the ADDIE stages of Analysis, Design, Development, Implementation, and Evaluation. Effectiveness testing was conducted during the implementation phase involving 66 Grade XI Motorcycle Engineering students, consisting of 32 students in the experimental class and 34 students in the control class. Data were collected through validation sheets, practicality questionnaires, and pre-test/post-test instruments. The developed system achieved an average validity score of 94.44% and a practicality score of 84.21%, categorized as Very Valid and Very Practical. Learning outcomes in the experimental class improved based on the Paired Sample t-test, with mean scores increasing from 80.28 to 90.16. The N-Gain score was 0.42, categorized as moderate, and slightly higher than the control class score of 0.39. Practical performance was higher, with mean scores of 89.23 and 78.41 respectively. These findings indicate that the developed system is effective.
