Abstract

One of the efforts to increase income is utilizing non-timber forest products in the form of home industries. One of the non-timber forest products utilized by the community and have a business opportunity is the Nipa plant (Nypa fruticans Wurmb). It grows along rivers near estuaries to rivers with brackish water influenced by tides and is included in the mangrove/brackish forest type. The research aimed to analyze the utilization level of nipa (Nypa fruticans Wurmb), examine the income level of the nipa roof craftsman, measure the contribution level of the nipa roofing business to family income, and analyze the relationship between the income level and the utilization of nipa (Nypa fruticans Wurmb). Data was sampled using the census method. The respondents were the craftsmen of nipa roofs (only ten people were still active in making nipa roofs). The required data includes the utilization of nipa resource products, production costs, total revenue, selling price, income from the nipa roofing business, and income from other family members. The results showed that the total production of nipa palm roofs was 303,840/year. The average income of nipa roof craftsmen was Rp10,732,200/year. The income contribution of the nipa roof craftsmen to family income was medium (55%). The utilization of nipa forest resource products had a very strong and positive relationship in increasing the income of nipa roof craftsmen with a correlation value of 0.842.

Abstract

The purpose of this study was to examine changes in the physical and chemical properties of natural peat forests and peatlands designated for oil palm plantations at various ages of oil palm planting. The research was carried out in 4 (four) locations in East Kotawaringin Regency, namely: (1) Natural peat swamp forest in Kota Besi District (2) Peat land designated for oil palm plantations planting age less than 4 years in Parenggean District; (3) Peat land designated for oil palm plantations with a planting age of 4-10 years in Cempaga District; and (4) peat land designated for oil palm plantations with a planting age of more than 10 years in Mentawa Baru District, Ketapang. The results showed that the peat land designated for oil palm plantations caused changes in the physical and chemical properties of the peat soil. Changes in the physical properties of peat soil are indicated by the color of the peat soil which changes from very dull red in natural peat forests to reddish black in oil palm plantations. Peat maturity changes from fibric in natural peat forest to hemic and sapric on peatland designated for oil palm plantations. The water content has decreased significantly, the older the age of the oil palm plant, the water content will decrease. In terms of bulk density, the older the age of oil palm plantations, the higher the density of peat soils. The water level in oil palm plantations has increased when compared to natural peat forests. Changes in chemical properties were indicated by an increase in peat soil pH, total N, and available P, while a decrease occurred in the C-Organic content. An increase also occurred in the content of K-dd, Ca-dd, Mg-dd, Na-dd, and CEC with increasing age of oil palm plants. When viewed from the relationship pattern of each physical characteristic, water content has a positive relationship with fiber content, the higher the water content will be followed by the higher fiber content or vice versa. Bulk density has a negative relationship with fiber content and moisture content, which means that an increase in the bulk density of peat soil will be followed by a decrease in fiber content and moisture content. The relationship pattern of chemical properties shows that the pH (H2O) of peat soil has a positive relationship with organic C, total N, available P, and Cation Exchange Capacity (CEC). High or low peat acidity will be proportional to the high or low -organic, N-total, P-available, and Cation Exchange Capacity (CEC).

Abstract

This study aims to identify the types, frequency, and intensity of pest attacks on seedlings in the Permanent Nursery, Tumbang Nusa, Central Kalimantan. Nurseries play a vital role in supporting the rehabilitation and conservation of tropical rainforests. Pest attacks on seedlings can reduce plant productivity, cause seedling shortages, and hinder growth, ultimately affecting the success of forest rehabilitation efforts. The research was conducted through field surveys and direct observations to identify the types of pests attacking the seedlings.The results showed that six types of pests (grasshoppers, bagworms, crickets, nettle caterpillars, bush snails, and armyworms) attacked forest seedlings (Shorea balangeran, Alstonia spatulata, Tengkawang, and Shorea leprosula) in the Permanent Nursery managed by the Watershed and Protected Forest Management Center (Balai Pengelolaan Daerah Aliran Sungai dan Hutan Lindung) in Tumbang Nusa. The highest percentage of pest attacks on seedlings in the nursery was observed in Shorea balangeran (grasshoppers, 56%), Shorea leprosula (grasshoppers, 37%), Tengkawang (crickets, 51%), and Alstonia spatulata (grasshoppers, 34%).The intensity of pest attacks on the four seedling types in the nursery ranged from low to high damage categories (6% - 17%). The highest pest attack intensity occurred in Shorea balangeran at 17% (grasshoppers), Shorea leprosula at 11% (crickets), Tengkawang at 16% (crickets), and Alstonia spatulata at 10% (grasshoppers, bush snails, and armyworms). This study highlights the importance of nursery management, including seedling selection, routine fertilization, and weekly insecticide spraying, to minimize pest attacks and maintain seedling quality.
