Abstract

Changes of land cover from forest to non-forest areas affect the hydrological cycle and water quality in watershed ecosystems, such as the change of forest into oil palm plantation areas. Increased production and extention of oil palm plantations have impacts on the environment and water quality, which have become one of the environmental issues. The study was conducted to provide an overview of the erosion and surface runoff from forest and oil palm plantations and their impacts on the water quality. Erosion plots with the size of 15 m × 25 m were made on Jalemu Watershed, Gunung Mas Regency, Central Kalimantan Province. The research was conducted to study the impact of land cover changes on erosion and surface runoff and nutrient loss into the Jalemu River Basin. Sampling of sediments and runoff water was carried out from the erosion plots, inlcuding water sampling from Jalemu watershed. The results showed that the erosion and surface runoff that occurred in the 5 years old oil palm area were higher than in the forest area, which implied the loss of nutrients from oil palm plantation areas and the potential for water pollution by the nutrients.

Abstract

This study aims to describe the techniques of rattan processing and the production process of rattan handicrafts, analyze the income of rattan artisans, and identify the challenges faced by artisans in Tumbang Habangoi Village. The research employed a saturated sampling method (census) and collected data through observation, interviews, and questionnaires. Data were analyzed using revenue and income analysis, as well as qualitative descriptive methods. The findings indicate that the rattan processing and crafting stages typically involve soaking the rattan, drying the stems, cleaning the stems (locally known as maruntih and mangalingking), processing, cutting, and splitting the rattan stems and strands, skinning, thinning, and weaving. The resulting woven products include mats, bags, lanjung (traditional backpacks), baskets, tangok, embung, tampi, pot coasters, and bubu (fish traps). The average annual production cost is IDR 449,875, with an average annual revenue of IDR 1,522,500 and an average annual income of IDR 1,246,750. The primary challenges identified include limited market access and a lack of product innovation, which hinder the development of rattan handicrafts in the community.
