Abstract

A food self-heater is a device designed to rapidly heat food by the utilization of exothermic or endothermic reactions. To yet, a food self-heater with a dedicated scent feature has not been developed. The fragrance utilized is derived from residual tangerine peel components. The objective of this study is to investigate the variations in the concentration of the limonene compound in essential oil extracted from tangerine peel, specifically examining the impact of tangerine peel wilting. Additionally, the study intends to identify the most effective food self-heating method by incorporating tangerine peel powder as an aromatic component in the self-heating process. The present study employed a Completely Randomized Design (CRD) consisting of five treatments and three replications. The treatments employed in this study encompassed varying durations of withering time for tangerine peel, denoted as A (0 hours), B (6 hours), C (12 hours), D (24 hours), and E (48 hours). The research findings indicated that the duration of drying tangerine peels had a notable impact on various factors including water content, yield, pH, color, duration for the aromatic self-heating meal to attain the optimal temperature, and aroma. However, no significant influence on limonene levels was seen. Based on the duration required for the aromatic food self-heater to attain the optimal temperature and the organoleptic aroma, treatment D (24-hour withering of tangerine peel) demonstrates the highest efficacy. This treatment exhibits a time frame of approximately 4.5 minutes for the aromatic food self-heater to reach the optimum temperature, accompanied by a fragrance rating of 4.2 in the organoleptic analysis.

Abstract

The research results show that: (1). All liquid waste requirements for land application have been fulfilled properly, even the biodegradation results in anaerobic ponds are much smaller than those required by Environmental Impact Control Agency, (2). Water quality standards in monitoring wells in gardens are based on PP No. 82 of 2001 Class II, BOD-5 and Total Nitrogen do not meet quality standards, but at the resident monitoring well location almost all parameters tested meet quality standards, COD is smaller and even oil and fat are not detected and the Total Nitrogen content is only 2.38 mg/l which has met the requirements. Waste seepage into residents' wells is not significant; (3). The results of plantations that use land applications and non-land applications are different, where the results of gardens that use liquid palm oil mill waste as land applications produce much greater fruit production (average yield is greater/ha 48.28%) than the results of oil palm plantations. (4). The use of fertilizer on land application land was initially greater than on land that did not use land application land, this was because agricultural yields had actually started to decline because they were over 20 years old, but the use of fertilizer was decreasing every year, and (5). The oil content of fresh fruit bunches (FFB) applied to garden land and non-land application shows a difference in oil content, where fresh fruit bunches (FFB) applied to garden land on average have a greater oil content than fresh fruit bunches.

Abstract

The article presents the results of experiments conducted in the Karshi district of the Kashkadarya region to improve the reclamation condition of moderately saline soils, enhance the efficiency of irrigated land use, and achieve higher crop yields. Considering the region’s water scarcity, a water-saving “Chemical” method was employed to improve the reclamation state of saline soils. To ensure the leaching of salts to lower soil layers, irrigation rates exceeding the standard by 25% and 50% under water scarcity conditions were applied, and these methods were compared with traditional approaches to study the soil’s water-salt regime. The chemical ameliorant SPERSAL, recommended by the Swiss company “Sibo-Novartis,” was used as a soil amendment at a rate of 5 kg/ha. When applied to the soil before irrigation or mixed with irrigation water, SPERSAL induces an ion exchange reaction in the soil adsorption complex, displacing sodium cations with calcium and magnesium cations. Salts such as sodium chloride, sodium sulfate, and sodium bicarbonate formed in the plant root zone dissolve in irrigation water and leach into lower soil layers. Key parameters studied include soil water absorption, field capacity, capillary rise height of soil moisture, the amount of water-soluble salts in irrigation, drainage, and groundwater, as well as soil moisture dynamics. Calculations for the water required for leaching and irrigation of saline soils, along with the economic efficiency of the applied variants based on cotton yields, were determined according to the “Methods of Conducting Field Experiments” (Tashkent, 2007) guidelines.

Abstract

Goat farming has a lot of promise in the highland area of Limapuluh Kota Regency in West Sumatra. However, ecological pressure may result from goat population development that is not balanced with land suitability assessments. Goats’ ecological land suitability will be examined in this study using biophysical, socioeconomic, and environmental carrying capacity metrics. The research methodology include field surveys, local farmer participation, and geographic analysis utilizing Geographic Information Systems (GIS). The findings indicated that 91.7% of the district of Limapuluh Kota is suitable for goat rearing. Because of the land elevation over 1,500 meters above sea level and the excessive rainfall exceeding 2,500 mm, 8.3% of the area is categorized as not suitable (N). According to the study’s findings, the growth of goat farming in Limapuluh Kota District must take ecological zoning into account, giving precedence to land areas that are appropriate for intense development and the use of silvopastura systems. These results offer a solid foundation for planning cattle sustainably in tropical highlands.
