Sat, 04 Apr 2026 00:00:00 +0700

Introduction/Main Objectives: Liberica coffee (Coffea liberica W. Bull ex Hiern) is one of the leading commodities in Jambi Province, but its productivity tends to decline due to low seed quality, less fertile planting media, and suboptimal fertilization. One effort to improve seed quality is through the use of organic fertilizer bokashi lamtoro (Leucaena leucocephala L.). This study aims to determine the effect of bokashi lamtoro on the growth of Liberica coffee seedlings in nurseries and determine the best dose that provides optimal growth. Research Methods: The study was conducted in June–August 2025 at the Teaching and Research Farm, Faculty of Agriculture, University of Jambi using a Completely Randomized Design (CRD) with five treatments and four replications. The treatments consisted of P0 (no bokashi + 100% inorganic fertilizer), P1 (100 g bokashi + 50% inorganic fertilizer), P2 (150 g bokashi + 50% inorganic fertilizer), P3 (200 g bokashi + 50% inorganic fertilizer), and P4 (250 g bokashi + 50% inorganic fertilizer). Finding/Results: The results showed that Treatment P4 produced the highest values for most growth parameters. However, in terms of efficiency, the dose of 200 g bokashi leucaena (lamtoro) + 50% inorganic fertilizer was considered the best dose because it was able to produce optimal seedling growth with more efficient bokashi use. Conclusion: It can be concluded that bokashi leucaena is effective in increasing the growth of Liberica coffee seedlings during the seedling phase.

Elisa Elisa, Muhammad Rachmad R, Rahma Nurjanah — Sat, 04 Apr 2026 00:00:00 +0700

Introduction/Main Objectives: This study aims to analyze the effects of interest rates, exchange rates, world oil prices, and inflation on the IDX BUMN20 during the 2019–2024 period. The IDX BUMN20 represents state-owned enterprise (SOE) stocks that play a strategic role in the national economy and, in recent years, have shown relatively lagging performance compared to the Composite Stock Price Index. Background Problems: The performance gap between the IDX BUMN20 and the Composite Stock Price Index indicates differences in sensitivity to macroeconomic dynamics, making it important to examine the short-run and long-run effects of macroeconomic variables on the index. Research Methods: The study uses monthly secondary time series data from 2019–2024 obtained from the Indonesia Stock Exchange, Bank Indonesia, Statistics Indonesia, and the Federal Reserve Bank of St. Louis. The data are analyzed using the Autoregressive Distributed Lag (ARDL) model. Finding/Results: In the long run, the IDX BUMN20, interest rates, and world oil prices tend to have positive effects, while the exchange rate tends to have a negative effect in the initial period and inflation appears relatively weak. In the short run, the effects of the variables are dynamic and vary across lags. Conclusion: The findings confirm that the performance of state-owned enterprises (SOEs), as reflected in the IDX BUMN20, is strongly influenced by macroeconomic conditions. Therefore, strengthening corporate governance, managing exchange rate and financing risks, and ensuring policy stability are essential to sustain the strategic role of SOEs as development agents and contributors to government revenue.

Muhammad Bonie, Ida Nursanti — Sat, 04 Apr 2026 00:00:00 +0700

Introduction/Main Objectives: Rejuvenation method (replanting) in oil palm plants is the process of replacing old or unproductive plants with new, superior plants so that plantation productivity remains high and sustainable. The choice of rejuvenation method depends, among others, on the condition of the plant and the condition of the land. This study aims to determine the growth of immature oil palm and bulk density in several rejuvenation methods. Research Methods: The materials used are 2-year-old Tenera variety oil palm plants from Sampoerna Agro. The tools used are plastic plates, paint, cameras, stationery, meters, Global Positioning System, Dial thicknesses, sample rings and Krisbow light meters. The design used in this study is a Randomized Block Design with one treatment factor, namely the oil palm rejuvenation method, namely L0: new land clearing method, L1: insertion planting pattern (underplanting), L2: total uprooting planting pattern. Each treatment was divided into three groups, with 10 plant samples taken from each group. Observed parameters were plant height, stem circumference, leaf thickness, soil density, and light intensity. Observational data were analyzed using ANOVA. If significant differences were obtained, the DNMRT test was performed at the α level of 5%. Finding/Results: The rejuvenation method significantly affected plant height and stem circumference growth. The interplanted oil palm rejuvenation method resulted in the highest average increase in stem height, while the highest growth in stem circumference and leaf thickness was found with the new land clearing method. The new land clearing method had the lowest bulk density, at 1.32 g/cm³.
