Abstract

People's dependence on rice is currently very high and this need must be met by imports, so that the need for imports is certain to increase from time to time, both in terms of quantity and purchase price. Indonesia is currently ranked 63rd out of 113 countries in terms of food security, The Increasing consumption of rice is also one of the causes of the increase in the number of diabetes sufferers, considering that rice is a product with a high GI value. One solution that can be done is to replace rice with artificial rice made from cheap local ingredients with a low GI value. One of them is corn which is a leading local commodity. Politeknik Negeri Jember has conducted research on the ideal formulation of artificial rice, namely using 50% corn and 50% mocaf and has optimized the artificial rice making tool, namely a single screw extruder. The aim of this research is to produce a method for making artificial rice with low GI, economical and affordable using local corn and mocaf fermented with L. plantarum 15420 bacteria and produced using a single screw extruder and studying the chemical and physical aspects of artificial rice. The resulting artificial rice has an ash content of 0.52%, , amylose conten of 13.11%, amylopectin conten of 30.28% (with a ratio of 31:68), protein conten  of11.2%, Ca conten of 0.04%, fat conten 0.5%, water conten of 11.3% and resistant starch conten of 6.4%. The GI value of artificial rice is 51.2. Regarding the feasibility study, the R/C ratio value was 1.31. The price of the artificial rice Polije produces is affordable for the entire community at Rp. 37,500,- per package (2.5 kg) which is more economical compared to IR64 rice.

Abstract

Piperine obtained from Javanese long pepper extract is an essential compound, but it has the disadvantage of being insoluble in water, so its bioavailability is low. One of the efforts that can be made to overcome this is by changing the size to nano, such as making nanoemulsion preparations. The study aims to determine the effect of VCO:Tween 80 ratio and homogenization time on nanoemulsion characteristics of Javanese long pepper extract. The research method utilized a completely randomized design by treating VCO:Tween 80 ratio and homogenization time. The research parameters included an organoleptic, percent transmittance, pH, viscosity, piperine content, particle size, polydispersity index, and zeta potential. This research resulted in a percent transmittance value of 97.05-99.55%, pH 4.89-5.56, viscosity 0.35-0.76 cP, piperine content 6.29-12.25%, particle size 41.482 nm and 266.62 nm, polydispersity index 0.7446 and 0.4358, zeta potential -4.443 mV, and -2.166 mV. The study is expected to be a reference in utilizing piperine content to benefit spices and medicines.

Abstract

Landslides have occurred in several tropical regions of Indonesia and caused many losses in both upstream and downstream areas. This study aims to identify landslide prone areas in the Wadaslintang catchment area, Central Java Province Indonesia. Nine parameters were used to analyze landslide potential such as land use, land slope, rainfall, constituent rocks, soil type, soil permeability, population density, drainage density and runoff coefficient. Each parameter has five possibility scores ​​(1 to 5) determined based on certain criteria. The value of each parameter was presented in a raster map with 15 meters of resolution and analyzed in ArcGIS 10.8. The level of landslide susceptibility was classified into five categories.  The relationship between landslides and the triggered factor was analyzed using Frequency Ratio (FR). The result showed that the parameters with the highest FR values were land use, land slope, rainfall, and soil permeability, indicating a strong influence on landslides. Very high vulnerability areas were found in mixed farmland and settlements especially on steep slopes. Area with moderate and low categories of landslide vulnerability covers the largest area of the study site with an occupied area of 98.54 km2 (51.04% of the total area) and 57.91 km2 (29.99% of the total area), respectively. While the others i.e., areas with the very low, high and very high categories, occupy around of 3.74 km2 (1.94% of the total area), 30.94 km2 (16.02% of the total area), and 1.93 km2 (1% of the total area) respectively. Validation results indicated that landslides mostly occurred in areas with medium and high categories of landslide vulnerability.

Abstract

Durian, known as the "King of Fruits," is a prevalent fruit in Indonesia, thriving in the tropical climate of Southeast Asia. One of the most widely cultivated varieties is Bawor, commonly found in Banyumas Regency, Central Java, producing 95,426 quintals in 2024. The price of Bawor durians ranges between Rp. 85,000 to Rp. 120,000 per fruit, weighing between 2 to 4 kg. Durian grows optimally in lowland areas up to 180 meters above sea level, with a humid climate, air temperatures of 25-32°C, humidity levels of 50-80%, and sunlight intensity of 45-50%. The research aims to build an information system called "SiDurIoT" based on the Internet of Things (IoT) integrated with a Geographic Information System (GIS) to evaluate the suitability of Bawor durian land. Land evaluation is classified S1, S2, S3, and N. Durian Information System with Internet of Things "SiDurIoT" is a device designed to measure the suitability of durian orchards in real-time. The device consists of a DHT22 sensor, a wind speed sensor, and GPS connected to the ESP32, with data displayed on an LCD screen. The device is connected to the internet via the website siduriot.my.id and the "SiDurIoT" smartphone application, which allows users to input measurement data. The results of the land suitability assessment show that wind speed, rainfall, soil pH, soil temperature, and land elevation are highly suitable (S1). In contrast, air temperature is suitable (S2), and humidity and sunlight intensity are marginally suitable (S3). Based on the suitability evaluation, the Kemranjen, Sumpiuh and Tambak areas are the most suitable locations for durian plantations because they have productivity above 10,000 quintals and are very suitable (S1).

Abstract

The Forest Area with Special Educational Purposes (KHDTK) at Muhammadiyah University of Mataram, covering 93.55 hectares, has undergone enrichment with eucalyptus and agarwood plants since 2019. In 2024, further enrichment is planned with durian, avocado, jackfruit, and longan. However, concerns have arisen regarding the suitability of the KHDTK area for durian cultivation, necessitating a land suitability evaluation. This study aims to determine the suitability classes, limiting factors, and management recommendations for durian and other selected plants. Using a rigid grid method, a soil survey and evaluation were conducted, assessing 14 parameters related to soil, climate, and land. The findings indicate that the land suitability for durian falls into class S3, with limiting factors including coarse soil texture, low levels of nitrogen, phosphorus, and potassium, insufficient rainfall, and a slope of 16-30%. Recommended management strategies include the application of organic and NPK fertilizers, installation of pipe irrigation, and contour-aligned planting. Enrichment with durian in the KHDTK area is suggested to be developed. This study contributes to sustainable land management by providing scientific data for durian cultivation in KHDTK areas. In addition, the results can support the development of conservation-based agroforestry and agritourism.

Abstract

Processing guava into dried candied is an alternative to extend the shelf life of guava. The purpose of this study was to estimate the shelf life of dried candied guava in polypropylene plastic packaging at any storage temperature. Through changes in the values of the quality parameters, the shelf life of candied guava at various storage temperatures was determined using the Accelerated Shelf Life Testing (ASLT) method of the Arrhenius model. Dried candied guava that had been packaged in polypropylene plastic packaging (0,08 mm thickness) and then was stored in an incubator with several storage temperatures, which are 35ºC, 40 ºC, 45 ºC, and 50ºC. Quality analysis was conducted on changes in water content, color value, and vitamin C. Estimation of the shelf life of the Arrhenius model is based on critical quality parameters, in this study the deterioration of vitamin C content is the critical parameter. The shelf life of dried candied guava in polypropylene plastic packaging when stored at 20˚C is 282 days, at 25˚C storage is 134 days, and storage at 30˚C lasts up to 65 days. Shelf life will increase if the dried candied guava is stored at a lower temperature and vice versa.

Abstract

Continuous consumption of fossil fuels can cause fuel prices to rise and potentially cause shortages. One alternative renewable energy that can replace fossil fuels is biomass pellets. The use of manual biomass pellet stoves has constraints in controlling the amount of biomass burned, the amount of heat released by the stove, combustion efficiency, safety, and wasteful use of pellets. The purpose of this study was to develop a biomass stove using an automatic control system as a substitute for gas or electric stoves. This stove has the same principle and working method as gas stoves in general, but the pellet fuel is solid. This technology controls the temperature through the integration of temperature sensors, fan blowers, screw feeders, and heat insulators automatically. The results showed that the stove temperature value with the coefficient of determination value from sensor calibration 1 was R2 = 0.9945, sensor calibration 2 obtained the value R2 = 0.9956, the R2 value in sensor calibration 3 was 0.9946, and sensor calibration 4 obtained the value R2 = 0.9927. In the system response test, the device was able to reach a temperature of 300°C in 450 to 780 seconds. Stability testing for setting points 100°C, 200°C, and 300°C were 0.98, 0.82, and 0.53, respectively. The accuracy of the device was 92%. In the execution speed test, it took 2.5 to 4 seconds for the pellets to enter the fuel furnace.

Abstract

Honey has significant health benefits due to its rich content of nutrients, enzymes, and bioactive compounds. However, conventional processing methods such as pasteurization can potentially degrade the physical and chemical quality of honey, including moisture content, density, total soluble solids, viscosity, and color stability. This study examines the effectiveness of the Evaporator Vacuum Cooling Four in One technology in maintaining the quality of Acacia honey compared to various pasteurization durations. The results show that vacuum cooling technology significantly preserves honey quality in terms of moisture content, density, and total soluble solids at a better level than conventional methods. Additionally, vacuum cooling optimally maintains honey's viscosity and color, demonstrating its superiority in reducing damage to bioactive components. This study is expected to contribute to the development of more efficient honey processing technology in the industry, aiming to provide high-quality honey that meets consumer health standards.
