Abstract

This research discusses the utilisation of solar power plants (PLTS) in supporting salt production through a hybrid system with PLN electricity. The main objective is to design and optimise an efficient and sustainable renewable energy system, especially in remote areas with limited electricity supply and to determine the needs of PLN electricity and solar panel energy systems during the salt cooking process. This research method collects data by measuring various important components, such as the voltage from the inverter to the stove supplied from PLN electricity and solar panels to the battery. The test results show that salt production requires 700 watts of power from PLN for 1.5 hours with an average voltage of 195-196 volts and a current of 3.3-4 amperes. The voltage of the solar panel to the battery stabilised at 12.58 volts during sunny weather and decreased to 12.21 volts during cloudy weather. This research shows that the solar power plant for salt production has worked effectively. By building a hybrid system of PLN and solar panels to ensure the sustainability of salt production, especially in overcoming the instability of the power generated by solar panels due to weather changes

Abstract

Base isolators are designed to protect structures from earthquake impacts by decoupling horizontal ground motion from the building. This technology is widely applied to bridges, buildings, and critical facilities due to its efficiency in reducing damage risks. This study aims to evaluate the effectiveness of base isolators in minimizing dynamic structural responses to earthquakes. Numerical simulations were conducted to compare the performance of structures with and without base isolators, focusing on maximum acceleration, velocity, and displacement. The results indicate that base isolators reduce maximum acceleration by 75.1%, velocity by 74.83%, and displacement by 34.79%. Therefore, base isolators have proven to significantly enhance structural resilience against earthquakes. These findings provide practical insights for designing safer and more earthquake-resistant buildings

Abstract

Pests plague farmers both during planting and after harvest. One of the pests that most often causes crops to fail during harvest time is rats. These pests usually attack communities of tens to thousands of people, causing a lot of losses. Since rat pests attack close to harvest, farmers usually drive rats out of the fields. This research method uses the R&D method. This research aims to assist farmers in repelling rat pests to get good quality rice. The test that will be used is a partial test. Where, partial tests that will be carried out on sensor parts are sensor movement tests, LoRa data transmission tests and LoRa distance measurement tests. The LoRa-based rat repellent system uses a combination of sensors and ultrasonic frequency transmitters to detect and repel rats. With LoRa (Long Range) technology, the system can send and receive data remotely with little power, which enables real-time monitoring and control of devices over a wireless network. Test results show that the system can function optimally under various environmental conditions, has a wide communication range, and responds quickly to pests. This shows that the integration of LoRa in the rat repellent system can improve pest control more efficiently and environmentally friendly than conventional methods.

Abstract

Kale (Brassica oleracea var. sabellica) is a high-value vegetable that requires adequate lighting to support photosynthesis, especially when cultivated using a hydroponic system. This study aimed to examine the effect of LED lighting and reflector use on kale growth using the Deep Flow Technique (DFT). The research was conducted in September 2024 at the Horticultural Research Center, MARDI Serdang, Malaysia, using a Completely Randomized Design (CRD) with three treatments: 4 lamps (4L), 4 lamps with reflector (4 LMR), and 5 lamps (5L), each repeated five times for a total of 1,000 plants. Observed parameters included plant height, number of leaves, chlorophyll content, and Leaf Area Index (LAI). The results showed that the 4 LMR treatment produced the best growth, with the highest number of leaves, the highest chlorophyll content, and good LAI values. The use of reflectors effectively increased light absorption efficiency and photosynthesis. In contrast, the 4L treatment showed the lowest growth due to poor lighting and nutrient deficiencies. Overall, the MARDI reflector proved effective in enhancing kale growth in a DFT hydroponic system.

Abstract

This study aimed to extract chitin from rice grasshoppers using the Deep Eutectic Solvent (DES) method. The chitin extraction process involves several stages, namely delipidation, demineralization, and deproteination. In the demineralization and deproteination stages, two extraction methods were compared, namely the conventional method using strong acids and bases and the environmentally friendly method using Deep Eutectic Solvent (DES). The conventional method uses hydrochloric acid (HCl) for demineralization and sodium hydroxide (NaOH) for deproteination. DES is an effective solvent in dissolving proteins without damaging the chitin structure. This success was evidenced by test parameters of fat content from 30.91 to 9.01 with a DL percentage of 70.85%. In the ash content test, it was proven that the % ash content in pure grasshoppers was 4.87% and decreased in the demineralization process to 1.38% for the extraction stage using DES from 1.25 in the extraction process using the conventional method, this shows that the demineralization extraction process was successful in reducing mineral levels. In the protein content test, pure grasshoppers were 53.57% decreased in the deproteination process using DES to 1.11% and in the conventional method using NaOH, it decreased by 1.65%, this proves a decrease in protein content in the deproteination stage. In the chitin extraction process, an infrared spectrum analysis (FTIR) was also carried out on the extracted chitin samples.

Abstract

Bean plants are one of the groups of legumes that are popular with the public. In addition, beans are one of the sources of vegetable protein, vitamins A, B, and C found in their seeds. The demand for beans is increasing every year. Fertilization is an effort to increase the harvest of a plant cultivation. The use of organic fertilizers, both liquid and solid, can be a solution to reduce excessive application of inorganic fertilizers, because organic fertilizers can improve the physical, chemical, and biological properties of the soil. The purpose of this study was to determine the effect of giving Guano fertilizer and SP-36 fertilizer doses on the growth and yield of bean plants. This study used a Factorial Randomized Block Design with 2 factors: Factor l, namely Guano fertilizer (G) with 4 levels, namely: G0 = 0 g/plant (Control), G1 = 30 g/plant, G2 = 60 g/plant and G3 = 90 g/plant. Factor 2, namely the provision of SP36 (K) fertilizer with 4 levels, namely: K0 = Control (0 g/plant), K1 = 1.5 g/plant, K2 = 3 g/plant, K3 = 4.5 g/plant. The parameters observed in this study include plant height, number of branches, number of pods/plant and weight of pods/plant. The results of the study showed that the provision of Guano fertilizer had no significant effect on plant height, number of primary branches, number of pods and weight of pods. Guano fertilizer is a biological fertilizer that is given to add organic material to bean plants
