Abstract

A problem encountered in oil palm cultivation on tidal acid sulfate soils is the pyrite content. If pyrite in the soil oxidizes, it will increase soil acidity and metal content, thereby impacting oil palm root growth. This study aims to analyze the chemical properties of acid sulfate soils at various depths within the sulfuric horizon and their impact on oil palm root development at PT. Sumber Asih Kebun Paya Rambe II, Aceh Tamiang. The study used a soil survey method with an exploratory-descriptive approach, including soil profile identification and the collection of 32 composite soil samples at four depths (0–20, 20–40, 40–60, 60–80 cm) in two blocks with different sulfuric horizon depths. pH analysis was performed using a pH meter in a soil-water suspension (1:2.5), while AI and Fe contents were determined using Atomic Absorption Spectrophotometry (AAS) after wet digestion. To evaluate root development, 8 root samples were taken purposively and analyzed using the oven-dry weight method (105°C). The results showed the lowest pH at 60–80 cm, namely 4.5 (Block 27) and 5.0 (Block 24). The highest AI content was also found in the same layer, namely 5.2572% and 3.7582%, while the highest Fe content was at a depth of 0–20 cm, respectively, 3.1274% and 2.8684%. Root development decreased significantly in locations with shallow sulfuric horizons, indicated by a decrease in root dry weight of 34–38% compared to locations with deeper sulfuric horizons. This study confirms that the position of the sulfuric horizon directly affects soil acidity, AI mobilization, and reduced oil palm root growth in acid sulfate soils.

Abstract

Oil palm (Elaeis guineensis) is one of the most important plantation crops in tropical regions, yet its productivity is often threatened by the rhinoceros beetle (Oryctes rhinoceros), a major pest that damages growing points and significantly reduces yields. Understanding the habitat and breeding potential of this pest is essential for sustainable management strategies. This study was conducted at Sei Silau Estate, PTPN III, Asahan Regency, to examine potential breeding sites of O. rhinoceros in immature plants (TBM), mature plants (TM), and empty fruit bunches (EFB). A total of 381 individuals were collected, with the highest population found in TM (206 individuals), followed by EFB (107 individuals) and TBM (68 individuals). The larval stage dominated up to 88.19%, particularly the third instar. These findings indicate that organic materials such as fronds, decaying trunks, and EFB are highly suitable habitats supporting the life cycle of O. rhinoceros. Therefore, organic waste management is essential for sustainable pest control, while manual hunting can serve as a complementary strategy within an integrated pest management framework in oil palm plantations.

Abstract

Robusta coffee seeds (Coffea canephora) exhibit relatively long physiological dormancy, which often constrains seedling production. One approach to accelerate seed germination is soaking seeds in gibberellic acid (GA₃). This study aimed to evaluate the effect of GA₃ soaking duration at 250 ppm on germination and early seedling growth of robusta coffee seeds. The experiment was arranged in a Completely Randomized Design (CRD) with a single factor, namely GA₃ soaking duration, consisting of five levels: 0, 12, 24, 36, and 48 hours. Observed parameters included time to dormancy breaking, germination percentage, root length, hypocotyl length, percentage of cotyledon opening, and fresh weight of seedlings. Data were analyzed using analysis of variance (ANOVA), followed by Duncan’s Multiple Range Test (DMRT) at the 5% significance level. The results showed that GA₃ soaking duration significantly affected dormancy-breaking time, germination percentage, root length, hypocotyl length, and seedling fresh weight, but had no significant effect on cotyledon-opening percentage. Soaking seeds in a GA₃ solution (250 ppm) for 24–36 hours produced the best response, as indicated by faster dormancy-breaking, higher germination percentage, and better early seedling growth. Excessive soaking duration tended to reduce treatment effectiveness. Therefore, an appropriate GA₃ soaking duration is recommended to improve robusta coffee seedling establishment.

Abstract

Oil palm is a strategic commodity in Indonesia, contributing significantly to rural income and regional economic development. However, inefficiencies in the supply chain, particularly at the village level, often reduce the economic benefits farmers receive. This study aims to analyze the supply chain structure and the effect of marketing channels on the income of oil palm farmers in Terawas Village, Musi Rawas Regency. This study employed a quantitative descriptive approach, using a survey, with a purposive sample of 60 farmers. Data were collected from primary and secondary sources and analyzed using descriptive methods, combined with marketing margins, farmers’ shares, and benefit-cost ratio (R/C) models. This study offers novelty by providing empirical evidence at the village level that integrates multiple efficiency indicators simultaneously, a feature that remains limited in previous research. The results show three main marketing channels: farmers–middlemen–palm oil mills, farmers–collectors–palm oil mills, and farmers–direct to mills. Shorter marketing channels are more efficient and generate higher income for farmers. The highest marketing margin occurs in the longest channel (Rp700/Kg), while the lowest is in the direct channel (Rp400/Kg). The highest farmer’s share is found in the direct channel (84%), compared to 72% in the middlemen channel. The R/C ratio indicates that all channels are profitable, with the highest efficiency in the direct channel (1.75). This study recommends strengthening farmer institutions, improving access to market information, and promoting direct marketing channels to reduce dependency on intermediaries and enhance supply chain efficiency.
