Abstract

Onion is one of the commodities of annual vegetable crops that have high economic value, a type of short-lived plant, can be propagated vegetatively or generatively, can be developed in low to highland areas and can be cultivated throughout the year. High demand for onions was not followed by supply of onion in the market. This is caused by high risks in the cultivation of  Onions. As the theory of supply, the level of supply of a commodity will be affected by the amount of commodities produced. The research aims to analyze the risk factors for onion production and onion supply behavior. The method of this research was survey methode. The location of this research was at Tonjong, Kramatwatu subdistrict. The population of onions farmers was 117 farmers and the amount of the sample used in this research is 54 farmers. Sort of datas that used in this research were primary data and secondary data. The analysis data that used are risk analysis, and multiple linear regression analysis. The results showed that the level of risk of onion in Tonjong Village was 1621.91 or 32 percent of the productivity value obtained by farmers. The source of the risks on Onion farming in Tonjong Village are climate and weather, pests and plant diseases, land fertility, and the effectiveness of using inputs. There are two factors that significantly influence the behavior of onion offering in Tonjong  Village, the cost variable of fungicide and the variable cost of insecticide.

Abstract

 Small and Medium Enterprises (SMEs) in the food processing sector often face challenges in managing raw material inventories efficiently, which can affect operational sustainability. This study aims to analyze inventory control of sweet potato procurement in a local SME producing processed food. Data were collected through interviews with three key informants (owner, production supervisor, and procurement staff), direct observation of raw material handling, and documentation of purchasing records, complemented by literature review. A descriptive quantitative approach was applied using calculations of Safety Stock, Minimum and Maximum Inventory Levels, Reorder Point, and Economic Order Quantity (EOQ). Results indicate that the optimal inventory range lies between 5,160 kg (minimum) and 6,420 kg (maximum). The EOQ method suggests an ideal order size of 732.04 kg per cycle, reducing annual inventory costs to IDR 464,787, which is lower than conventional ordering practices. Efficiency of inventory control was recorded at 10.19%, highlighting the need for structured methods to improve effectiveness. The findings demonstrate that systematic inventory management can minimize storage and ordering costs, prevent shortages or excess stock, and enhance operational efficiency. This research contributes to strengthening inventory management practices in SMEs engaged in local food processing.

Abstract

This research investigates the impact of productive land area, production volume, the rupiah exchange rate against the US dollar, and international prices on Indonesia's dry natural rubber export volume from 2015 to 2024. Secondary data were sourced from the Central Statistics Agency, the Ministry of Agriculture, and Bank Indonesia. The analytical approach employed multiple linear regression, incorporating classical assumption tests and hypothesis testing to validate the model. Partial results reveal that productive land area, exchange rate, and international prices exert a negative yet insignificant influence on export volume. In contrast, production volume demonstrates a positive and significant effect, underscoring that higher output can substantially boost exports. Simultaneously results the four independent variables significantly affect export volume, as evidenced by an Fvalue of 97,446 exceeding the Ftable value of 5,19 and a significance level of 0,000 below 0,05. The R² value of 0,987 suggests that 98,7% of the variation in export volume is accounted for by these factors. These findings highlight the critical role of enhancing production efficiency and implementing economic stabilization measures to improve the global competitiveness of Indonesia's rubber exports.

Abstract

This study aims to analyze the influence of the agricultural and non-agricultural sectors on regional economic growth in Depok City during the 2020–2024 period. Although agricultural land area has declined to 157.42 hectares in 2024, this sector exhibits a paradoxical phenomenon in the form of an increasing growth rate, thereby necessitating a strategic evaluation of its development potential. Using Gross Regional Domestic Product (GRDP) data, this study applies the Location Quotient (LQ), Basic Service Ratio (BSR), Regional Investment Multiplier (RIM), Shift Share, and Klassen Typology methods. The results indicate that the economy of Depok City is driven by ten base sectors, including construction, trade, and financial services. Although the agricultural sector is classified as a non-base sector with an average LQ value of 0.50, it falls into the category of a potential sector in Quadrant III of the Klassen Typology due to its growth rate of 17.76 percent, which significantly exceeds the average growth rate of the reference region. Furthermore, a BSR value of 1.70 and an RIM value of 1.58 indicate that each one-unit increase in growth in the base sector is able to generate a substantial stimulus to non-base sector activities as well as an overall increase in regional income. This study concludes that despite the ongoing process of economic modernization, the agricultural sector in Depok City remains competitive.
