Application of Tobit Regression on Household Expenditure on Egg and Milk Consumption in Bengkulu City
Get PDFRegression analysis is a statistical method used to examine the functional relationship between two or more independent variables and a dependent variable. One of the regression methods designed to handle censored data or data with significant zero values is Tobit regression. This study aims to model household expenditures on egg and milk consumption in Bengkulu City using Tobit regression and to identify the factors influencing these expenditures. The data were obtained from the 2022 National Socioeconomic Survey, with a total sample of 1,170 households. The Tobit regression model was chosen because most household expenditure data had zero values, indicating censored data characteristics. This study identified several factors affecting expenditures on egg and milk consumption, such as the household head's education level, the number of household members, and the household head's employment sector. The results showed that the education level of the household head (elementary, junior high, and high school), the number of household members, and the household head's employment in agriculture and trade sectors had significant impacts on household expenditures for egg and milk consumption. The education level of the household head and their employment sector had a negative relationship, while the number of household members showed a positive relationship with these expenditures. The Tobit regression model successfully modeled household expenditures with adequate accuracy, as indicated by a Mean Absolute Percentage Error (MAAPE) of 1.38%

Gender-Based Analysis of Technical Efficiency in Rice Farming: A Case Study in Deli Serdang Regency
Get PDFDeli Serdang Regency is the foremost rice grower in North Sumatra Province. The disparity in input access between male and female producers is responsible for the low rice output in this region. This study aimed to assess the technical efficiency of rice cultivation among male and female producers and identify the inefficiency sources among rice farmers in Deli Serdang Regency. We employ a stochastic frontier methodology to assess the technical efficiency of rice cultivation and utilize a statistical difference test to evaluate efficiency disparities between the two cohorts of rice growers. Primary data was gathered from 400 farmers during the 2022 planting season. The study revealed that male rice growers exhibited greater efficiency than their female counterparts. Our findings indicate that male rice producers inadequately utilized labor, fertilizer, land, and pesticides, but female rice producers inadequately utilized labor and fertilizer. Factors contributing to inefficiency also included the frequency of extensions, experience with FBOs, agricultural expertise, and access to irrigation. Given that women dedicate considerable time to domestic responsibilities and child-rearing, local governments may establish extension and training initiatives—such as guidance on fertilizer application, pest management, and agricultural record-keeping—alongside health programs routinely administered at integrated service posts (Posyandu) and family welfare programs (PKK). Extension services are essential to enhance the knowledge and abilities of women rice farmers, hence improving technical efficiency, household welfare, and the sustainability of rice growing in Deli Serdang Regency
Export Competitiveness of Indonesian Cocoa Derivative Products in Main Destination Countries
Get PDFThe purpose of this study is to examine the competitiveness of Indonesian cocoa derivative product exports, especially cocoa paste, cocoa butter, and cocoa powder, to the main destination countries: Malaysia, China, the Philippines, the United States, and India and to analyze the export trends of cocoa derivative products to make a forecast for the next 10 years. Data analysis includes the RCA (Revealed Comparative Advantage), ECI (Export Competitiveness Index) and ARIMA models. The results show that Indonesian cocoa paste has significant competitiveness in Malaysia, China, the Philippines, and the United States, but not in India because the RCA value is < 1. Indonesian cocoa butter and powder have a high competitive advantage in the main destination countries, indicated by the RCA value> 1. Indonesian cocoa paste, cocoa butter, and cocoa powder have been competitive since 2005 to 2022, indicated by the average ECI score > 1. In addition, the projection of Indonesia cocoa paste export prospects to major destination countries shows an increasing trend from 2023 to 2032, except for the Philippines which is expected to decline during that period, with an average of only 142.51 tons per year. The projection of the quantity of Indonesia cocoa butter exports to major destination countries shows an increasing pattern. The projection of the amount of Indonesia cocoa powder exports to Malaysia, China, the Philippines, and India is on an increasing trajectory; however, in the United States, it shows fluctuations with a downward trend with an average of 1,899,175 tons per year

Efektivitas Seed Coating pada Benih Cabai Rawit (Capsicum frutescens L.) Varietas Bara yang Kadaluarsa
No full text[EFFECTIVENESS OF SEED COATING ON EXPIRED ‘BARA’ BIRD’S EYE CHILI (Capsicum frutescens L.) SEEDS]. The decline in physiological quality of bird’s eye chili (Capsicum frutescens L.) seeds due to prolonged storage poses a significant challenge in horticultural crop production, particularly in ensuring the availability of high-quality seeds. This study aimed to evaluate the effectiveness of seed coating using carboxymethyl cellulose (CMC) and humic acid in combination with Plant Growth Promoting Rhizobacteria (PGPR) in enhancing the viability and vigor of aged ‘Bara’ chili seeds. The experiment was conducted from March to June 2025 at the laboratory, field, and greenhouse facilities of the UPT for Rice and Palawija Seed Development, Singosari, Malang, East Java. A factorial completely randomized design (CRD) was employed with two factors: type of coating material (CMC, humic acid, and CMC + humic acid) and PGPR dosage (10 g and 20 g). The observed variables included maximum growth potential, germination rate, vigor index, and seedling growth rate. The results indicated that treatment with 1% humic acid + 20 g PGPR yielded the highest maximum growth potential and germination rate (100%), while the combination of 1% humic acid + 10 g PGPR produced the highest vigor index (33.33%) and growth rate (5.89%/day). The application of organic coating materials combined with PGPR was proven effective in restoring the physiological quality of aged chili seeds. These findings can be implemented as a seed invigoration strategy to extend the shelf life of horticultural seeds and improve seedling establishment under field conditions, thereby supporting sustainable crop production systems.
