Abstract

One of the widely used post-harvest processing methods for aloe vera is drying, given its high water content. An effective drying method is vacuum freeze-drying, although this method has a drawback in energy efficiency. This research examines the use of paraffin wax as a Thermal Energy Storage (TES) medium to utilize waste heat from the condenser during the freezing phase in a vacuum freeze-drying system. The results of the study show that the use of TES consistently improves drying efficiency and energy savings. The system with TES was able to remove a higher moisture content compared to the test without TES, at 68% for a 2 kg load versus 58.57% without TES. In addition, the Coefficient of Performance (COP) for the system with TES was recorded at 2.23, which is higher than the 2.08 without TES. The use of TES for 2 kg also resulted in an electrical energy saving of 259 Wh. Thus, TES in a vacuum freeze-drying system is effective in enhancing energy efficiency, reducing power consumption, and improving the drying performance of aloe vera.

Abstract

The increasing concern over greenhouse gas emissions from fossil fuels has driven the exploration of hydrogen as a clean energy source. However, the practical application of hydrogen in internal combustion engines is still limited by the stability of on-demand hydrogen production systems and their integration with conventional engines. This study aims to design and evaluate a NaOH-based alkaline electrolyzer for on-demand hydrogen production and its application in a small spark-ignition engine. The electrolyzer was fabricated using 8 cell stacks with electrode dimensions of 16×16 cm, an inter-electrode gap of 2 mm, and a thickness of 1.2 mm. Experimental tests were conducted at currents of 40 A and 50 A with 30 wt.% NaOH solution. The produced hydrogen gas was directly supplied to a 97cc spark-ignition engine under a constant braking load of 0.5 kg/cm². The result showed that hydrogen production reached 0.9 L/min at 40 A and 1.25 L/min at 50 A. The addition of hydrogen significantly improved engine performance, with brake power increasing by up to 20.8%, brake thermal efficiency by 6.2%, and volumetric efficiency by 9.1%, while reducing brake specific energy consumption by 28%. These findings indicate that hydrogen generated from an alkaline electrolyzer can enhance combustion efficiency and improve overall engine performance, supporting the development of cleaner and more efficient energy systems.

Abstract

Energy audit is a technique used to analyze the amount of energy consumption in buildings and identify ways or methods to save it. Based on the Minister of Human Resources Regulation No. 13 of 2012 stated rules regarding energy management and energy saving standards. Shopping buildings are one of the sectors that use electrical energy to operate. A bookstore in Pekanbaru which consists of three floors also uses electrical energy for lighting and air conditioning systems. The use of electricity for lighting and air conditioning for a month is 37985.5 kWh and then ECO is carried out so that the use of electrical energy can be reduced to 30,138 kWh in each month. The use of electrical energy can be expressed in Energy Consumption Intensity (IKE), before the ECO IKE was carried out for the 2nd and 3rd floors of the bookstore building in Pekanbaru was 28.59 and after energy saving opportunities, the Energy Consumption Index became 23.09.

Abstract

Desa Sumber Sari, Kabupaten Kampar, merupakan salah satu wilayah pertanian yang masih menghadapi permasalahan berupa serangan hama tanaman, ketergantungan petani terhadap insektisida kimia, serta belum optimalnya pemanfaatan limbah organik dari aktivitas pertanian dan rumah tangga. Kondisi ini mendorong perlunya alternatif teknologi sederhana berbasis sumber daya lokal yang ramah lingkungan, murah, dan mudah diterapkan oleh masyarakat. Kegiatan pengabdian ini bertujuan untuk mengimplementasikan teknologi pembakaran sampah bebas asap dalam mengkonversi limbah organik menjadi insektisida alami di Desa Sumber Sari, Kecamatan Tapung Hulu, Kabupaten Kampar. Metode yang digunakan adalah pendekatan partisipatif-terapan melalui tahapan identifikasi kebutuhan, perancangan alat sederhana berbasis prinsip pirolisis, pelatihan produksi asap cair, serta pendampingan aplikasi di lahan pertanian. Hasil kegiatan menunjukkan bahwa proses pembakaran terkendali mampu menghasilkan cairan kondensat dengan karakteristik menyerupai wood vinegar, yang mengandung senyawa asam organik dan fenolik dengan potensi insektisida. Variasi frekuensi pembakaran mempengaruhi kualitas produk, di mana kondisi optimum diperoleh pada pH 4–5 yang sesuai untuk aplikasi pertanian setelah pengenceran. Selain menghasilkan produk fungsional, kegiatan ini juga meningkatkan kapasitas teknis petani dalam mengelola limbah biomassa secara mandiri. Implementasi teknologi ini berkontribusi terhadap pengurangan limbah, penurunan emisi dari pembakaran terbuka, serta penguatan praktik pertanian berkelanjutan di tingkat lokal.

Abstract

The implementation of the Closed Rotary Lemang Baking Machine at Rumah Lemang MSME in Pekanbaru improved burning time efficiency by 50%–62.5% per batch. However, field evaluation revealed a critical capacity gap: machine capacity (10 bamboo/batch) was significantly lower than traditional production capacity (40 bamboo/batch), resulting in lower actual throughput (6–7 bamboo/hour vs. 10–13 bamboo/hour) and reduced daily output (20–30 vs. 40 bamboo). This study analyzed this gap through throughput analysis and identified second-generation machine requirements using Voice of Customer (VoC). Methods included in-depth interviews with the MSME owner, production performance measurement, and comparative gap analysis. VoC results identified an ideal capacity of 50 bamboo/batch, with the owner already planning an independent modification as an indication of active technology adoption. This study recommends an iterative development approach with modular second-generation machine specifications grounded in real user needs.
