Abstract

Determinant Factors of Harvest Labor Productivity in Oil Palm (Elaeis guineensis) Plantation at PT Danar Rimba Raya. Oil palm plantations play a strategic role in Indonesia’s economy by contributing significantly to export earnings and rural employment. However, productivity challenges in labor-intensive harvesting activities remain a critical issue affecting production efficiency and sustainability. This study aims to analyze the productivity of harvest workers and identify the factors influencing it at PT Danar Rimba Raya Pelantaran Estate, Kotawaringin Timur Regency, Central Kalimantan. In 2024, the company’s production realization reached only 80% of the target, with a worker attendance rate of 90%. A descriptive quantitative approach was employed using a census method involving 24 harvest workers. Data were collected through questionnaires, field observations, and interviews, and analyzed using multiple linear regression. The results show an adjusted R² value of 0.958, indicating that 95.8% of productivity variation was explained by the model. Partial test results revealed that work experience had a significant negative effect (β = –0.217; p < 0.05), while incentives had the strongest positive influence on productivity (β = 0.632; p < 0.01). Other variables, including age, motivation, tool availability, and work environment, were not statistically significant. These findings emphasize the importance of performance-based incentive systems and adaptive labor management strategies to enhance productivity in the oil palm plantation sector.

Abstract

Growth and Yield Response of White Radish (Raphanus sativus L.) to the Application of Rabbit Urine and KCl Fertilizer in PMK Soil. Radish (Raphanus sativus L.) is a root vegetable of the Brassicaceae family, closely related to cabbage. Based on data from the Central Statistics Agency of West Kalimantan (2021), the productivity of radish in West Kalimantan in 2020 decreased compared to the previous year. Increasing radish production can be achieved through agricultural intensification using Podsolik Merah Kuning (PMK) soil (Ultisol). The main problem of PMK soil is its low fertility. One way to improve the chemical properties of PMK soil is to apply organic fertilizer, namely rabbit urine liquid fertilizer, and inorganic fertilizer, namely KCl. This study aimed to determine the best concentration of rabbit urine and the most effective dose of KCl fertilizer for the growth and yield of white radish in PMK soil. The research was conducted in the experimental field of the Faculty of Agriculture, Tanjungpura University, Pontianak City, from September 15 to October 30, 2024. The experiment used a factorial completely randomized design with two factors. The first factor was rabbit urine concentration (U) at three levels: u1 = 20 ml/L, u2 = 40 ml/L, and u3 = 60 ml/L. The second factor was the KCl fertilizer dose (K) at three levels: k1 = 0.8 g/plant, k2 = 1.2 g/plant, and k3 = 1.6 g/plant. The results showed no interaction between rabbit urine concentration and KCl fertilizer on the growth and yield of white radish in PMK soil. Individually, rabbit urine at 20 ml/L and KCl fertilizer at 0.8 g/plant gave the best results on radish tuber length. However, no optimal and effective dose was found to significantly improve the growth and yield of white radish in PMK soil.

Abstract

Inventory and Analysis of Barriers to Increasing Areca Nut Productivity in Sungai Kakap District, Kubu Raya Regency. Areca nut productivity in Kubu Raya Regency is relatively low, at around 0.86 tons/ha, compared with the national average of 1.53 tons/ha. This indicates that there are still many problems in areca nut farming in Kubu Raya Regency. Based on this, research is needed to inventory and analyze obstacles to increasing areca nut productivity, with the results informing recommendations for policy interventions in Kubu Raya Regency. The research was conducted in Punggur Besar Village, Sungai Kakap District, Kubu Raya Regency, and is a descriptive study using a survey method with respondents as research objects. Primary data were collected using a questionnaire to obtain systematic, objective information on farmer characteristics, technical, economic, and external obstacles experienced in running areca nut farming, while secondary data were obtained from relevant agencies and the literature. The results of the study concluded that areca nut farming in Sungai Kakap District, Kubu Raya Regency is still faced with various obstacles, namely: (1) farmers' limited access to information and technology about good and correct areca nut cultivation, (2) farmers can only sell dried areca nuts to collectors at low prices, (3) farmers do not have access to other sources of financing besides their income, and (4) the role of institutions has not been fully felt by farmers, there has been no special guidance and ongoing technical assistance regarding areca nut farming including its financing.

Abstract

Screening of Ganoderma Antagonistic Fungi from Palmae Roots in Kubu Raya Regency, West Kalimantan, Indonesia. Basal stem rot (BSR) disease, caused by the pathogen Ganoderma sp., is the most important disease in palms (Arecaceae, formerly known as Palmae). To date, there is no effective method for controlling Ganoderma. In oil palms, several methods developed can only slow the rate of infection or extend the plant's productive period. Biological control is an alternative method for controlling Ganoderma and is currently under development. However, the development of biological control is hampered by its limited distribution. The most feasible approach is to identify effective indigenous antagonists from the rhizosphere of palms and develop methods for their utilization. This is because the palm family is a group of plants with high species diversity, so it is suspected that they also have a high diversity of rhizosphere fungi. Therefore, it is suspected that there are fungi antagonistic to Ganoderma that can be used as biological control agents against Ganoderma sp. This effort can be done by isolating and screening microorganisms from the rhizosphere of palm plants for their ability to act as antagonists against Ganoderma, and testing their activity in the rhizosphere of palm plants under various combinations of environmental factors thought to support their effectiveness in controlling Ganoderma. Specifically, this research aims to identify Ganoderma antagonists from the rhizosphere of palm plants in West Kalimantan that are effective in controlling BPB disease. The research has been conducted by isolating and testing the ability of fungi from the roots of palm plants in West Kalimantan in controlling Ganoderma sp. The results showed that 50.97% of fungi isolated from palm roots inhibited Ganoderma growth in vitro, with inhibition ranging from 70% to 83%. Given this ability, further testing is needed to determine the effectiveness of these fungi in controlling stem rot disease caused by Ganoderma in palm plants.
