Abstract

One of the alternative energies that can be developed is hydrogen. To obtain hydrogen gas by decomposing air compounds (H2O) into hydrogen hydrogen oxygen gas (HHO) through electrolysis. considering the limited energy from the currently available mining materials is increasingly depleted. In order to overcome the above, one solution is to utilize the existence of alternative energy forms by utilizing electrical energy in the form of hydrogen gas stored in H2 which also comes from air (H2O) which can now be used for energy. Through this method, a catalyst is added to improve combustion efficiency in the HHO generator and after research, the addition of 14 grams of catalyst was able to increase energy as seen from the height of the flame 16 mm from the electrolysis process.

Abstract

CVT (Continuous Variable Transmission) components have several components that must be considered, one of which is the roller component that is often used on the 2013 Beat automatic motorbike. The rollers found on automatic motorbikes consist of two types. The rollers have different masses on both parts. Based on the mass of the two types of rollers, a study was conducted using the experimental method, which is a form of study to find cause and effect (causal relationship) between two factors by eliminating or reducing or setting aside other interfering factors. The study was conducted to determine the effect of replacing the roller with a mass of 15 grams on power, torque and top speed on the 2013 Honda Beat motorbike. The testing tool used in this study used a dynamometer that was able to analyze the effect of roller mass on the power generated by the automatic motorbike and also the centrifugal force of the roller. The lighter the roller weight, the smaller the centrifugal force generated. However, at high engine speeds, centrifugal force will decrease faster than rollers that have a heavier weight. The torque obtained in the use of 13 gram and 15 gram rollers respectively is 9.24 Nm, 8.79 Nm obtained at 6000 rpm engine speed. While the top speed obtained from the use of 13 gram roller is 75.06 km / h in 1 second, and the top speed achieved by the 15 gram roller is 78.65 km / h in 1 second.

Abstract

Waste is a problem in Indonesia, both organic and non-organic waste. Bambo powder is an organic waste that can still be utilized to produce energy using the pyrolysis method. The research aims to utilize bambo waste to produce tar using pyrolysis process with temperature variation and with the addition of zeolite. The research method uses 200 g of bamboo powder with a moisture content of less than 2% and 40 g of zeolite and a heating process with a duration of 3 hours. The pyrolysis gas was condensed to obtain tar. The research produced the most tar products at a temperature of 550 ⁰C as much as 57 milli and 72 milli in the addition of zeolite. In the pure pyrolysis process, the highest calorific value was obtained at a temperature of 450 ⁰C amounting to 149.27 (cal/g) at the addition of zeolite, the highest calorific value was obtained at a temperature of 550 ⁰C amounting to 248.29 (cal/g). This shows that adding zeolite to the pyrolysis process can increase the amount of tar when compared to pure pyrolysis both in quality and quantity.

Abstract

Biogas is a widely recognized alternative energy source among Indonesian communities. It is produced through the anaerobic fermentation of livestock manure and water, and can be combined with other organic waste materials to enhance gas production. The addition of organic waste in biogas production has been shown to significantly influence the quantity and quality of the resulting gas output. Therefore, this research was conducted by introducing coffee dreg waste into the process to evaluate its effect on the production of methane (CH₄) and carbon dioxide (CO₂), using MQ-4 and MQ-135 gas sensors for detection. Data analysis revealed that the chemical components present in the added coffee dregs effectively increased the reaction rate during biogas production. This was demonstrated by the highest methane concentration achieved by the specimen with the largest coffee dreg content (444), reaching 247.033 ppm. Meanwhile, the highest carbon dioxide concentration was obtained from the specimen with a smaller amount of coffee dreg addition (441), measuring 141.202 ppm.

Abstract

Penelitian ini mengembangkan sistem berbasis Internet of Things (IoT) menggunakan sensor piezoelektrik untuk menganalisis frekuensi dan amplitudo getaran secara real-time pada blower ventilator guna mendeteksi keausan mekanis dan dampaknya terhadap penurunan laju aliran udara serta efisiensi blower. Sensor piezoelektrik dipilih karena kemampuannya yang tinggi dalam mengubah getaran mekanis menjadi sinyal listrik, sehingga mampu mendeteksi getaran terkecil sekalipun. Data dari sensor dianalisis secara real-time untuk mengidentifikasi tanda awal kerusakan mekanis yang memengaruhi performa mesin. Deteksi dini ini memungkinkan tindakan pemeliharaan yang lebih efektif dan efisien, mencegah kecelakaan kerja, serta menjaga keamanan proses sandblasting. Hasil pengujian menunjukkan perbedaan signifikan pada pola frekuensi getaran antara dua blower. Blower 1 memiliki frekuensi dan amplitudo getaran yang lebih tinggi dibanding blower 2, yang mengindikasikan adanya getaran kuat yang memengaruhi kinerja blower. Hasil uji laju aliran udara juga menunjukkan blower 1 memiliki aliran udara yang lebih rendah dibanding blower 2. Temuan ini menunjukkan bahwa frekuensi dan amplitudo getaran yang tinggi dapat menjadi indikator penurunan performa dan efisiensi blower ventilator.
