Abstract

This study analyzes the feasibility of industrial-scale pyrolysis of polyethylene (PE) and polystyrene (PS) plastic waste with a feedstock capacity of 200 kg per day. PE and PS plastics are pyrolyzed at temperatures of 400°C, 450°C, and 500°C until the feedstock is fully decomposed, indicated by the cessation of smoke emission from the reactor. The optimal conditions obtained are then used as a reference for energy calculations in a 200 kg industrial-scale process. The pyrolysis duration varies depending on the type of plastic and operating temperature, with the longest time recorded for PE pyrolysis at 450°C for 98 minutes, while the shortest time was observed for PS pyrolysis at 400°C for 31 minutes. The resulting heating rate indicates that higher temperatures lead to lower heating rates for both PE and PS plastics. The results indicate that increasing the temperature enhances the oil yield (v/wo) up to a certain limit before it begins to decline. The pyrolysis oil yield from PS plastic is higher than that from PE, as styrene monomers naturally exist in a liquid phase. The oil yield from PS remains relatively constant despite temperature increases, whereas the yield from PE follows an increasing trend before declining at the highest temperature. The decrease in PS pyrolysis oil density at higher temperatures also suggests differences in physical characteristics compared to PE. The energy consumption analysis indicates that PS plastic pyrolysis requires more energy than PE, with an average energy consumption of 75.14–77.57 kJ/g for PS and 18.7–33.94 kJ/g for PE. However, the oil yield from PS reaches approximately 79–80% of its initial weight, which is higher than that of PE pyrolysis oil. From an economic perspective, converting PE and PS plastic waste into fuel is not entirely feasible, as the energy produced is insufficient to sustain the pyrolysis process itself. The revenue from selling PE pyrolysis oil amounts to Rp 14,729,000 per month, while PS pyrolysis oil generates Rp 30,927,000 per month. Nevertheless, the social benefits of reducing plastic waste provide an added value that cannot be overlooked.

Abstract

This study aims to evaluate the impact of RLC loading on the power stability and power quality in Wind Power Plant (PLTB) systems. The RLC is applied to stabilize the power generated by the PLTB system, which tends to fluctuate due to wind speed variability. The testing was conducted by measuring the output power of the PLTB system loaded with various RLC configurations. The results show that RLC loading can enhance the apparent power stability and efficiency of the PLTB system. The resistive load (R) yielded the best performance, improving the power factor to 0.95 and maintaining relatively stable output voltage. Meanwhile, the LC loads exhibited lower efficiency with a reduced power factor, but still played a role in balancing reactive power. The reduction in reactive power for inductive and capacitive loads indicates that RLC loading can help reduce power waste and improve power quality. This research makes a significant contribution to the development of more efficient and stable PLTB systems and more reliable renewable energy-based power plants, particularly in managing power stability in the face of fluctuations caused by wind variability.

Abstract

Selama masa pandemi Corona Virus Disease 2019 (Covid-19), semua orang dituntut untuk dapat mengoperasikan media digital dengan kurang adanya pembelajaran tentang literasi digital yang baik. Panduan penggunaan aplikasi atau media digital saja belum cukup untuk meningkatkan kemampuan siswa-siswi sehingga muncul berbagai permasalahan yang menyebabkan adanya kemunduran prestasi. Kasus ini terjadi pada SD Miftahul Ulum berlokasi di Jalan Cokro Aminoto, Gg III Nomer 26, Kelurahan Kebonsari Kulon, Kecamatan Kanigaran, Kota Probolinggo. Memberikan tambahan bimbingan belajar dapat membantu mengejar ketertinggalan siswa-siswi dalam mempelajari materi. Namun, belum dapat membantu dalam peningkatan kemampuan menyerap materi pembelajaran. Selain itu, masa pandemi Covid-19 maupun pasca pandemi nanti siswa-siswi dituntut untuk memiliki kemampuan literasi digital yang tinggi. Kegiatan yang dilakukan telah direncanakan dan disusun menjadi enam tahap, yaitu tahap persiapan, asesmen, bimbingan belajar, pendampingan, implementasi, dan evaluasi. Melalui enam tahap tersebut, hanya terdapat dua jenis kegiatan utama yang dilakukan. Pertama, kegiatan bimbingan belajar bagi siswa-siswi yang kesulitan memahami materi pembelajaran akibat dampak pandemi Covid-19. Kedua, kegiatan pendampingan dalam memberikan pengetahuan mengenai literasi digital terhadap siswa-siswi. Setelah seluruh tahap kegiatan dilakukan, siswa-siswi yang mengalami kemunduran materi dapat kembali menyusul dengan baik. Selain itu, kemampuan siswa-siswi dalam memanfaatkan media digital juga semakin baik.

Abstract

Meningkatnya permintaan energi global mendorong pengembangan bahan bakar alternatif berkelanjutan dengan karakteristik pembakaran yang kompetitif terhadap petrodiesel. Penelitian ini mengkaji fenomena termofluida dinamis pembakaran droplet campuran petrodiesel dan biodiesel minyak kesambi, baik tanpa maupun dengan penambahan katalis nanopartikel TiO₂ 100 ppm. Komposisi sampel bahan bakar yang digunakan terdiri dari B0, B10, B20, B30, B40, dan B100, serta masing-masing komposisi dengan penambahan TiO₂. Parameter yang dianalisis meliputi penundaan penyalaan, durasi pembakaran, tinggi nyala api, suhu optimal, dan visualisasi nyala api. Hasil penelitian menunjukkan bahwa peningkatan fraksi biodiesel menghasilkan durasi pembakaran yang lebih lama hingga 6,83 detik pada B100 dan penurunan suhu puncak sebesar 734,76°C, dibandingkan dengan B0 yang memiliki durasi pembakaran selama 3,22 detik dan suhu puncak sebesar 794,54°C. Penambahan TiO₂ secara konsisten meningkatkan kinerja pembakaran, ditunjukkan oleh suhu puncak yang lebih tinggi hingga 821,76°C pada B0+TiO₂, penundaan pengapian yang lebih singkat, dan nyala api yang lebih stabil. Tinggi nyala api tertinggi teramati pada B0+TiO2 sebesar 53,79 mm dan terendah pada B100 sebesar 40,87 mm. Selain itu, penundaan pengapian tertinggi terjadi pada komposisi B100 sebesar 7,95 detik, sementara terendah terjadi pada komposisi B0+TiO2 sebesar 1,65 detik. Hal ini menunjukkan adanya hubungan antara komposisi bahan bakar dan intensitas pembakaran.

Abstract

Dependence on fossil fuels causes significant environmental damage and increases costs and scarcity in the future. To overcome this problem, a transition to renewable energy is needed, one of which is biodiesel which can be obtained from used cooking oil. This study aims to convert used cooking oil that cannot be reused into biodiesel products. Biodiesel synthesis can be carried out by the transesterification process, using NaOH catalyst with concentration variations of 0.5%, 0.75%, 1%, 1.25%, and 1.5% of the total mass of oil. The test parameters are calorific value, density, viscosity and flash point as well as yield on used cooking oil biodiesel products. The test results show that the use of a catalyst concentration of 1% produces more optimal density, viscosity, and calorific value and flash point. Each value is 0.859 g / cm³, 2.34 cSt, 10,356 cal / g, and 139°C. However, the use of a catalyst concentration of 0.5% shows that the biodiesel product is less than optimal. This can be shown by the highest density, viscosity and flash point values of the catalyst concentration variations used. Each value is 0.88 g/cm3, 3.16 cSt and 178°C, while the calorific value is also low with a value of 9,689 cal/g. However, when viewed from the yield, the catalyst concentration of 0.5% produces the highest value of all catalyst concentration variations used with a value of 88%.

Abstract

Kebutuhan energi yang masih ditopang oleh energi fosil menimbulkan efek ketergantungan pada sumber daya fosil. Energi fosil yang tidak tidak dapat diperbarui menjadi sebuah permasalahan yang terhadap konsumsi energi. Hal ini dikarenakan keberadaan energi fosil bersifat sementara. Oleh karena itu diperlukan langkah untuk mengurangi ketergantungan pada energi fosil. Salah satu langkah yang dapat dilakukan adalah memulai penggunaan energi alternatif. Salah satu energi alternatif yang dapat mengganti energi fosil adalah biopelet. Biopelet dapat diperoleh dari sumber hayati. Jika ditinjau dari kekayaan alam di Indonesia maka Indonesia kaya terhadap sumber keanekaragaman hayati. Penelitian ini dilakukan dengan cara memproduksi biopelet dari biji buah kesambi. Biji buah kesambi merupakan tanaman yang tidak tergolong bahan pangan sehingga cocok digunakan sebagai bahan baku sumber energi terbarukan. Biji buah kesambi diproduksi menjadi biopelet dan diuji karakteristiknya. Hasil pengujian menunjukkan bahwa nilai kalor rata-rata biopelet dari biji biji buah kesambi sebesar 5.520,22 kal/gram, kadar air sebesar 10,39%, kadar abu sebesar 0,318%.

Abstract

This community service program aims to improve the quality of honey products produced by small-scale producers in Probolinggo by implementing the Dehydrated Honey Machine. The main problem faced by partners is the high moisture content in honey (28%), which exceeds the Indonesian National Standard (SNI 8664:2018) limit of less than 22%. High moisture content reduces shelf life, product quality, and market acceptance, especially in pharmacies and online stores. The program was conducted through participatory methods consisting of socialization, training, technology implementation, and monitoring-evaluation. The Dehydrated Honey Machine with a capacity of 15 liters per 3 hours was installed at the partner’s production site, followed by training on operation and maintenance. After implementation, the moisture content of honey decreased to 17–18%, in line with the standard requirements. This improvement has extended the shelf life of honey, increased the selling price, and reduced product rejection. The program demonstrates that appropriate technology transfer effectively enhances production quality and competitiveness of local honey producers.
