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

The use of Scorodocarpus borneensis Becc as wood causes its availability in nature to decrease. An alternative step to utilize and maintain the availability of Kulim in nature is to utilize Scorodocarpus borneensis Becc’s bark extract. The bioactive substances and scent of Scorodocarpus borneensis Becc are considered capable of repelling insects and replacing DEET in chemical mosquito repellent raw materials. The use of Kulim wood extract is considered to be far better than the use of chemicals that can affect human health. This research was conducted in three laboratories, namely the forestry laboratory, organic chemistry laboratory and natural synthesis and chemical engineering laboratory. The parameters to know the quality of the extract from the bark of the Scorodocarpus borneensis Becc’s branch were yield observation, color observation, odor test and skin sensitivity, phytochemical test and the extract effectiveness test against mosquitoes which were expected to be in accordance with the criteria of the pesticide commission of the Department of Agriculture in 1995. The results showed that the yield from Scorodocarpus borneensis Becc’s wood extract was found to be worth 0.83%, the color of the extract was brown because it used water solvent, the distinctive aroma of the Scorodocarpus borneensis Becc was not found in the extract because it was dominated by tannins and the extract felt warm on the skin, phytochemical tests showed that the kulim extract contained substances such as saponins, phenolic, steroids and tannins as well as the effectiveness test of the extract against mosquitoes found a protection result of 44% which has not been able to meet the standard of repellent protection criteria from the Pesticide Commission of the Department of Agriculture in 1995.

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.
