Abstract

This study aims to analyze trends in palm oil production, analyze factors influencing palm oil supply, and determine the elasticity of palm oil supply in West Sulawesi. The research method used is quantitative descriptive. The study was conducted in West Sulawesi. The data used is time series data from 2004 to 2024, spanning 20 years. Data analysis used includes trend analysis, multiple linear regression analysis, and the supply elasticity formula.The results show an increasing trend in palm oil production from 2004 to 2024, although annual data shows a fluctuation pattern of 0.4198, or 41.98 percent per year, equivalent to 0.028 units of production per year. Factors simultaneously influencing palm oil supply include the previous year's palm oil price, the previous year's urea fertilizer price, the previous year's cocoa price, harvested area, and rainfall. The variable with a partially significant influence is the harvested area. If the area of ​​oil palm harvest increases by 1 percent, the supply of oil palm also increases by 0.276 percent per year. The elasticity value of the area of ​​oil palm harvested commodities in the short term is 3.50 and the long term is 4.38 elastic while rainfall has an elasticity value with a value of 0.39 in the short term and 0.49 in the long term on the supply of oil palm commodities in West Sulawesi.

Abstract

This study aims to analyze the levels of production risk, cost risk, and revenue risk, as well as the tolerable risk of loss (focus of loss) and minimum income of rain-fed lowland rice farming in the Tanakeke Islands District, Takalar Regency. Primary data collection methods used direct interviews (questionnaires) and field observations. A sample of 82 farmers was selected for this study. Data analysis used descriptive analysis and the Coefficient of Variation (CV). The results indicate that the highest risk of loss borne by rain-fed lowland rice farmers is cost risk, at 23.65 percent. Production risk, meanwhile, reached 13.74 percent and revenue risk, at 14.6 percent. Rain-fed lowland rice farming income is generated only in one planting season per year, averaging Rp 23,803,482.62 per hectare, with total farming costs of Rp 5,201,110.34 per hectare. The average household expenditure of rice farmers reaches Rp 16,423,225.61 per year. The minimum income earned by rain-fed rice farmers to continue farming and meet household needs is Rp 21,624,335.95 per year, with a tolerable or reasonable risk of loss accepted by rice farmers of Rp 2,179,146.67 per hectare. The focus of loss value or risk of loss that can be accepted by rice farmers is 9.15 percent, meaning that if the risk of loss occurs above this value, farmers will experience financial constraints in continuing farming and meeting their household needs.

Abstract

This study analyzes the volatility and trends of non-packaged and packaged palm cooking oil prices in traditional and modern markets and their correlation with monthly food inflation in Makassar City, Indonesia, over the period January 2021–December 2025. Monthly secondary time‑series data on retail palm cooking oil prices were obtained from the Food Security Agency of South Sulawesi Province, while food inflation data were sourced from Statistics Indonesia. Trend analysis using linear least squares and Pearson correlation were employed. In traditional markets, non-packaged palm cooking oil prices were relatively more stable (coefficient of variation, CV=0.1347) than packaged cooking oil grade I (CV=0.1430) and grade II (CV=0.1478), whereas in modern markets, packaged cooking oil grade I was slightly more stable (CV=0.1723) than grade II (CV=0.1745). Price trends were significantly upward for all product types, with monthly increases of Rp75.93/liter (non-packaged), Rp71.87/liter (packaged I), and Rp56.99/liter (packaged II) in traditional markets, and Rp127.05/liter and Rp107.71/liter for packaged grades I and II in modern markets, respectively (p < 0.01). Monthly food inflation for the food subgroup exhibited high volatility (CV=4.0836) but a statistically non‑significant declining trend of 0.0081 percentage points per month. Non-packaged and packaged cooking oil prices were strongly and positively correlated (r=0.739, p<0.001), indicating integrated price movements across market channels, while their correlations with food inflation were weakly negative and statistically insignificant (non-packaged: r=−0.168, p=0.199; packaged: r=−0.129, p=0.324). These results imply that, despite pronounced and synchronized increases in palm cooking oil prices, short‑run monthly food inflation in Makassar was driven more by other food commodities and macroeconomic factors than by palm cooking oil alone.

Abstract

This study aims to analyze the price fluctuations of beef, broiler chicken, and chicken eggs as sources of animal protein, as well as to analyze the correlation between commodity prices and food inflation in South Sulawesi Province, during 2021–2025. Secondary monthly time series data were obtained from the Strategic Food Price Information Center (PIHPS) and the Central Statistics Agency (BPS). Data were analyzed using coefficient of variation (CV) analysis and Pearson correlation. The results show that beef prices in modern markets fluctuate more (CV 9.16%) than in traditional markets (CV 8.01%), while wholesalers experience the highest volatility in the beef supply chain (CV 11.11%) compared to producers (CV 8.86%) and retailers (CV 8.51%). Broiler chicken prices were more stable in modern markets (CV 12.64%) than in traditional markets (CV 19.82%), but wholesalers again experienced the highest volatility (CV 31.07%), followed by producers (CV 28.56%) and retailers (CV 10.17%). Egg prices were slightly more stable in modern markets than in traditional markets (CV 19.45 vs. 20.24%), while producers recorded the highest volatility (CV 24.06%), followed by wholesalers (CV 21.13%) and retailers (CV 18.54%). Monthly food inflation averaged 0.331% and was highly volatile (CV 5.228%). Pearson correlation analysis revealed a strong and highly significant positive correlation between beef and egg prices (r=0.759; p<0.01), while the correlations between beef and broiler chicken, and between broiler chicken and eggs, were weak and insignificant. The correlation between each animal protein price and food inflation is negative and statistically insignificant, indicating that food inflation in South Sulawesi is mainly driven by other staple commodities.

Abstract

Negotiation and strategic positioning in international trade are crucial for maximizing the economic benefits of agricultural commodities. This study aims to analyze the determinants of the export competitiveness of coffee from South Sulawesi, Indonesia, during the 2010–2024 period. The independent variables examined include coffee production capacity, world coffee prices, and the exchange rate of the Indonesian Rupiah (IDR) against the US Dollar (USD), while the dependent variable is export competitiveness, measured by the Revealed Comparative Advantage (RCA) index. Utilizing an Ordinary Least Squares (OLS) regression model, the findings reveal that the model explains 70.5% of the variance in coffee export competitiveness. Statistically, both coffee production and the exchange rate exhibit a significant negative impact on the RCA index, suggesting structural vulnerabilities related to supply quality and high dependency on imported agricultural inputs. Conversely, world coffee prices do not significantly influence export competitiveness, indicating the position of local exporters as price takers bound by long-term forward contracts. These findings emphasize the urgent need for strategic policy shifts from quantity-oriented agricultural expansion to quality standardization and upstream cost stabilization.

Abstract

The research analyzes astrophysical phenomena in binary stars, fast stars, white dwarfs, and neutron stars, taking relativistic effects into account using Hipparcos catalog data. The objectives are to evaluate the relativistic precession of binary stars, the Shapiro delay due to the supermassive black hole Sgr A, the relativistic correction of neutron star luminosity, the distribution of star populations in the Hertzsprung–Russell diagram, the gravitational redshift of white dwarfs, and the characteristics of stars with extreme transverse velocities. Data from 10,726 binary star systems and 602 white dwarfs were processed numerically using R for data manipulation, visualization, and statistical calculations. The results show that relativistic precession in binary stars is generally small, increases in narrow orbits, and follows a power law with respect to the semi-major axis (exponent −0.453). Shapiro delay varies with projected distance to Sgr A, with most stars experiencing small delays, while some experience delays of up to 310 seconds. Neutron star luminosity shows a relativistic correction of ~0.03%, consistent with gravitational redshift and time dilation. The Hertzsprung–Russell diagram shows a clear separation between giants, main sequence stars, and white dwarfs, with a significant linear relationship between absolute magnitude and color index (B−V). The gravitational redshift of white dwarfs is controlled by radius (exponent −1.0001), while stars with extreme velocities form a heterogeneous and evenly distributed population. In conclusion, Hipparcos data support general relativity predictions and enable quantitative evaluation of stellar physics and evolution. Research novelties include systematic measurements of relativistic precession, Shapiro delay, neutron star luminosity corrections, white dwarf radius–redshift relationships, and kinematic characteristics of extreme stars.

Abstract

Penelitian ini bertujuan untuk menganalisis preferensi petani terhadap pembelian benih jagung hibrida serta menganalisis faktor-faktor yang memengaruhi preferensi tersebut. Penelitian ini menggunakan teknik simple random sampling dengan penentuan jumlah sampel menggunakan rumus Slovin. Teknik analisis data yang digunakan meliputi Mean Percentage Score (MPS) untuk menganalisis preferensi petani dan regresi linear berganda untuk menganalisis faktor-faktor yang memengaruhinya. Hasil penelitian menunjukkan bahwa sebagian besar petani (36,84%) memilih benih jagung hibrida merek NK212, diikuti Bisi 18 sebesar 35,09% dan Bisi 2 sebesar 28,07%. Preferensi tertinggi (69,80%) didasarkan pada faktor ketersediaan benih, sedangkan preferensi terendah (65,00%) didasarkan pada faktor kualitas benih. Hasil analisis regresi menunjukkan bahwa kualitas benih, ketersediaan benih, pendidikan, dan luas lahan garapan berpengaruh signifikan terhadap preferensi petani. Semakin tinggi kualitas dan ketersediaan benih serta tingkat pendidikan petani, maka semakin tinggi kecenderungan petani memilih benih jagung hibrida. Sebaliknya, semakin luas lahan garapan, maka kecenderungan memilih benih jagung hibrida semakin rendah.
