Abstract

Gambier cultivation location is usually carried out on sloping land which results in decreased land carrying capacity due to soil erosion. This research was to determine whether the factors of altitude and slope are related to the production of gambier plants and other factors related to gambier production. This research was conducted in Lima Puluh Kota Regency, West Sumatra in September 2020. The data collection methods is to use the interview method, observation and document study. Interview and observation methods were used to obtained gambier production data, gambier harvesting, gambier processing, general conditions of the research location, visual appearance of soil erosion, height of the gambier growing area, topography and soil type. Indirect data were collected using the document study method. The selection of informants was carried out by purposive sampling with a total of 10 people. Data analysis used qualitative descriptive analysis by linking the informants 'answers with document studies, then doing a description in the form of gambier production as outlined in the informants' responses. Altitude has no relation to the production of gambier, but the factors of price, treatment process, soil type and the choice of mixed plant species are factors related to gambier production in Lima Puluh Kota Regency. The slope factor has no relation to the production of gambier in Lima Puluh Kota Regency. Land owners still observe the principles of soil and water conservation by applying mulch (ground cover) from the dregs of gambier and conducting mixed planting with seasonal and annual plant types.

Abstract

Indonesia is the third richest country in Asia on bamboo resources. In Indonesia, bamboo has been widely used to substitute wood on many applications and also exported in certains bamboo products, such as sticks (used primarily for plaiting), charcoals, flooring, plywood, mats and screens, plaits and plaiting articles, pulp, and paper articles. This research aimed to analyse comparative and competitive advantages of Indonesian bamboo products in international market, including the factors effect its export growth on the period 2013 to 2017. Analysis was conducted under techniques RCA (Revealed Comparative Advantage), TSI (Trade Specialization Index) and CMS (Constant Market Share). Overall, the results showed that bamboo sticks and bamboo charcoals had strong and mature competitive advantages. However, bamboo flooring, bamboo plywood, bamboo mats and screens, and bamboo plaits and plaiting articles had weak competitive advantages and were on growing phase. Bamboo pulp and paper articles had had strong competitive advantages, but it was lessening to the phase of re-importing. The results of CMS analysis showed that commodity composition factor had positively affected export growth, while standard growth and competitiveness factors gave negative effect to Indonesian bamboo export growth.

Abstract

The Gajah Mungkur Reservoir (WGM) is located south of the center of Wonogiri Regency, Central Java. The variety of aquatic biotas, such as fish, in WGM is quite diverse due to the many rivers flowing into it. This identification is important because regions in Indonesia have a diversity of different types of fish and endemic types. The data collection locations were divided into four stations in the WGM. The diversity of nekton was studied using two methods, namely active and passive methods, and data were also collected on abiotic parameters, including TDS, water temperature, brightness, DO, and pH. The nekton found in this study consisted of 11 families comprising 15 species of fish and two species of shrimp. The dominant family was the Cyprinidae family, with six species: Hampala macrolepidota, Dangila cuvieri, Osteochilus vittatus, Barbonymus gonionotus, Rasbora argyrotaenia, and Oxyeleotris marmorata. The TDS levels ranged from 790-1050, water temperature from 28.9-30.4°C, brightness from 42-83 cm, DO from 3.55 to 4.8 ppm, and pH from 8.5-8.9. The Shannon-Wiener diversity index showed a value of 1.07-1.89, the evenness index ranged from 0.65 to 0.97, and the species richness index was within the 0.54-2.37 range. This sedimentation results in soil formation that local residents use for agriculture, especially in planting palawija crops. Sedimentation can also reduce the fishery areas within the reservoir and cause habitat displacement for nekton. Additionally, Mimosa pigra plants have been found to inhabit the sedimented soil, which may affect the water quality and ecosystem of the reservoir.
