Abstract

The palm oil industry is currently the main supporting sector of the economy from the plantation sector with the main product being Crude Palm Oil (CPO). East Kalimantan is one of the provinces as the center of palm oil production in Indonesia. This study aims to determine the factors that affect East Kalimantan CPO exports with the Ordinary Least Square (OLS) method approach. The variables included are East Kalimantan CPO Exports (Y), East Kalimantan Palm Oil Production (X1), East Kalimantan Total Exports (X2), and East Kalimantan GRDP (X3). The results of the analysis show that the model used is free from classical assumptions so that it can be interpreted. The F-test results show that the variables of palm oil production, total exports, and GRDP together have a significant effect on East Kalimantan CPO exports. The t-test also shows that the variables of palm oil production, total exports, and GRDP each have an effect on East Kalimantan CPO exports. The variables of East Kalimantan palm oil production (X1) and East Kalimantan total exports (X2) have a positive and significant effect on total East Kalimantan CPO exports, while East Kalimantan GRDP (X3) has a negative and significant effect on total East Kalimantan CPO exports.

Abstract

Palm oil (Elaeis guineensis Jacq.) is a strategic plantation commodity that plays a significant role in the Indonesian economy. One of the main factors determining palm oil productivity is the use of superior seeds with good initial vigor. This study aims to examine the morphological characteristics of three-month-old oil palm seedlings as an indicator of initial vigor that can be used as a baseline before the application of bio-amelioration technology using zeolite and Lactic Acid Bacteria (LAB) on post-mining land. The study was conducted at the pre-nursery stage by measuring parameters such as plant height, number of leaves, and stem diameter. Data analysis was conducted descriptively by calculating the average value. The results showed that the average seedling height reached 32.5 cm, the number of leaves was 4.2, and the stem diameter was 0.85 cm. These values ​​are within the international standard range for healthy three-month-old seedlings, thus they can be categorized as seedlings with fairly good vigor. This finding is important because initial morphological quality has been shown to have long-term implications for oil palm productivity. Furthermore, this baseline data serves as a benchmark for assessing the effectiveness of zeolite and LAB applications in further research on post-mining land which is generally poor in nutrients, acidic, and heavily degraded. Thus, this study provides an initial contribution to efforts to support sustainable post-mining land revitalization programs through mineral- and microbial-based bio-amelioration approaches.
