Abstract

Most of the social forestry program plantations in Bengkulu are in the form of mixed planting of coffee or rubber trees. The type of land use affects the production and decomposition of litterfall, which play an important role in nutrient cycle. The aim of the research was to determine the production and decomposition rate of litterfall in coffee (Coffee robusta) monoculture, coffee and Gliricidia sepium (gliricidia) agroforestry, and rubber (Hevea brasiliensis) monoculture. The research was arranged in a systematic design with three treatments and fifteen replications. The variables measured included production, composition, and decomposition rate of litterfall. The collected data were analyzed using T-test. According to the results, the litter production in coffee monoculture, agroforestry of coffee and gliricidia, and rubber monoculture was 1051.5, 1001.5, and 662.5 Kg ha-1 4 months-1 with the decomposition rate about 5.13, 4.25, and 5.28 gr m-2 4 months-1, consecutively.  The litterfall composition in the three types of land use consisted of leaf, twig, fruit, and flower. Leaf was the highest component of litterfall in coffee monoculture, agroforestry of coffee and gliricidia, and rubber monoculture, reaching 830.2 (78.99%), 646.7 (64.73%), and 391.0 (59.01%) kg ha-1, respectively. Nutrition analysis of leaf litterfall indicated that the highest content of C, N, P, and K was observed in agroforestry of coffee and gliricidia compared to other plantation types.

Abstract

Nocturnal insects are insects that are active in night time and responsive to light. These insects have a role in ecological processes in an ecosystem, including swamp ecosystem. The research was conducted at The Natural Recreation Park Danau Dendam Tak Sudah Bengkulu Province. The purpose of this study was to determine the abundance, diversity, and dominance of nocturnal insect species in The Natural Recreation Park Danau Dendam Tak Sudah. The method that be used was a black light trap of 20 watts, 220 volts, which emits low ultra violet light with a wavelength of 300 – 400 nm. The results showed that there were 16 species of insects (11 species in open swamps and 13 species in vegetated swamps), with the highest abundance of Hydrobius fuscipes (50.15% or 823 individuals), (12.49% or 205 individuals), and Aulacoscelis Sp. . (10.36% or 170 individuals). The swamp forest in the Natural Recreation Park Danau Dendam Tak Sudah has moderate diversity of nocturnal insects, with the value of H' value was about 1.69 in open swamps, 1.66 in vegetated swamps, and 1.75 in swamp forests. Nocturnal insects have low dominance, with the index value of dominance (D) was 0.27 - 0.29.

Abstract

Fruit fiber oil palm which be generated by the oil palm industries has a potential resource for a growth media. This study aims is to evaluate the effect of planting media based on the fruit oil palm fiber waste on the growth of sea pandan seedlings. This research was conducted in August - October 2020 at the Nursery and Laboratory of the Forestry Department, Faculty of Agriculture, Bengkulu University. The experimental design used in this study was a single factor CRD (completely randomized design), 5 treatments and 3 replications with 6 seedling each replication. The five treatmens was 1) 100% Palm Oil Fruit Fiber, 2) 100% Cow Manure, 3) combination of Palm Fruit Fiber Waste ((75%) and Cow Manure (25%), 4) Palm Oil Fruit Fiber Waste (50%) and Caw Manure (50%) and 5) Combination of Palm Fruit Fiber Waste (25%) + Cow Manure (75%). The results indicated that the different combination media resulted in the different of Pandanus laut growth. The combination media of Palm Oil Fruit Fiber Waste (75%) + Cow Manure (25%) gave the best growth of sea pandanus.

Abstract

Economic diversity has often been promoted as a means to achieve the economic goal of stability. Many empirical studies have also concluded that greater diversification in economic can reduce vulnerability and engendering financial development. The objective of this paper is to analyze the degree of economic diversification at village level. This research was conducted at twenty villages located around Kerinci Seblat National Park (TNKS) and determined purposively and surveyed. Twenty households from each selected village were selected using systematic random sampling method, so the total respondents were 400 households. Economic diversity at the village level was estimated using EDI suggested by Dewi, et al (2005).Research found that EDI value for each village studied varies from 0.20 to 1.00 with no village reaches 1.099, which is an ideal condition. The lowest EDI, i.e. 0.20, occurs in the village of Karang Dapo Atas and Karang Dapo Bawah, subdistrict of Bingin Kuning and the village of Ujung Tanjung II Subdistrict Embong Uram Karang. This value indicates that households in the village surveyed simply rely on one type of work, especially in the agricultural sector. This also means that not many households get into other employment sectors such as mining and or services/stalls/stores. By simply relying on agriculture as its main source of income, households tend to be vulnerable if there is a change in the agricultural sector, especially in sectors such as coffee and rubber plantations.
