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

LST and NDVI analysis in DAS Wanggu utilizes Landsat 9 satellite remote sensing. LST calculations usde thermal band 10 and NDVI used Red band (Band 4) and InfraRed Band (Band 5). There are 5 LST classes, 17.25 oC -19.66 oC with an area of 908.16 Ha, 19.66 0C-22.08 oC covering 6973.71 Ha, 22.08 oC -24.49 oC covering 21748.26 Ha, 24.49 oC -26.90 oC covering an area of 4235.37 Ha, and 26.90 oC -29.31 oC with a wide coverage of 81.18 Ha, while NDVI values obtained 3 classes namely NDVI <0.2 of 1783.643 Ha, NDVI with a range of 0.2 – 0.5 covering an area of 28617.74 Ha, and areas with NDVI > 0.5 covering an area of 3544.87 Ha. The amount of LST is highly dependent on the type of land cover and land use. NDVI indicates the presence of vegetation in the study area. A negative relationship was found between LST and NDVI in DAS Wanggu with a Correlation Coefficient of -0.179.

Abstract

Palm sugar is one of the products from aren (Arenga pinnata) which is classified as Non-Timber Forest Products (NTFPs) which has the potential to empower the community's economy. This research was conducted in Bontomanai Village, Bungaya District, Gowa Regency. The purpose of this study is to describe the management of palm sugar and calculate the income of palm sugar farmers. Descriptive analysis approach and income analysis are used as methods in analyzing the data obtained. The results showed that the process of managing palm sap into palm sugar was still managed in a simple and traditional way. The stages of managing palm sugar production which include tapping, cooking, printing, to packaging. Meanwhile, the total income of palm sugar is Rp. 361,081,967 per year with an average of Rp 9,758,967/household/year. The level of education of aren farmers, the productive age group, and the percentage of family dependents are an integral part of the results of this study.

Abstract

This research was based on the condition of the Ulubelu District area, which experienced a decrease in environmental quality and coffee yield productivity. Coffee plantations in Ulubelu District, Tanggamus have experienced a reduction in productivity over the last three years. This reduction in quality is due to the age of the less productive coffee plants (30-40 years) and the lack of shade trees. This study aims to determine the effect of shade trees on coffee productivity and land conditions in coffee agroforestry systems on farmers' land. This research was carried out to increase the productivity of coffee plantations economically and ecologically. The initial stage of this research is collecting secondary data on the application of agroforestry by coffee farmers in the Ulubelu area. The results showed that Ulubelu farmers had implemented agroforestry principles, but they are not optimal in terms of the percentage of shade trees and types of trees planted. Therefore, the recommendation is to plant shade trees of Indigofera sp. with the characteristics of deep roots and the leaves are used to feed cattle

Abstract

The Indonesian government is committed to reducing carbon and greenhouse gas emissions through the Forestry and Other Land Uses (FOLU) Net-Sink 2030 scheme. Efforts that can be made to support the FOLU Net-Sink 2030 is by knowing the carbon storage potential in a forest area. This research aims to calculate the amount of potential biomass carbon storage in the talang forest. The methods used in this research are non-destructive sampling and destructive sampling. The method with destructive sampling for seedlings, understorey and litters, while for saplings, poles, trees and necromass with non-destructive sampling method. The calculation results showed that carbon stocks were trees (77.76 tons/ha), poles (9.56 tons/ha), saplings (7.99 tons/ha), seedlings and understorey (0.65 tons/ha), litters (1.20 tons/ha) and necromass (2.39 tons/ha). Aboveground carbon storage in the talang forest was found to be 99.56 tons/ha. The total aboveground carbon storage potential of the gutter forest was 7,933 tons of carbon.

Abstract

It is feared that the natural growth of sago is unable to keep up with the high intensity of logging. Therefore, sago forest stands need to be managed properly and planned by organizing effective and efficient harvesting to minimize damage to live stands. The purpose of this study was to analyze the impact of logging on the damage of live stands. This research was conducted in Maluku Province, during October - December 2022. Data were collected by observing logging activities, measuring trees and making measuring plots with a size of 20 m x 20 m to measure damage to live stands. The results showed that the level of damage to live stands in the conventional logging system was higher at 31.82% when compared to controlled logging with a value of 12.42%. The productivity of controlled logging was higher than conventional logging. The level of damage to live stands and logging productivity in sago stands is highly dependent on the logging system carried out.

Resources management nature becoming point to important especially in maintaining benefits, continuity and sustainable natural source.Natural resource potential available with proper management would be of avail for human life.Natural resource potential can be attraction the community and can be used as tourist destinations. The area of tanjung bastian is one of the area who was in District North Central Timor are identical to the beach and also the racetrack and natural scenery. The effort to maintain the condition ecology in Tanjung Bastian related in such as planting tourism areas with the aim of land conservation as vegetation regeneration. A condition of vegetation survival in a stable and being able to compete with the physical condition of extreme environmental and climate condition, it is necessary to evaluate the extent to which the level of success of tree growth and the factors that influence it. Based on the results of observation plants who succeeded life 53 a plant consisting of 6 species with the numbers of life most there are to a species Delonix regia as many as 15 plants and the least species is Senna siamea with 3 plants. The classification of the assessment criteria vegetation that the level of success of success in the vetegasi Tanjung Bastian included in a category in quite poor repair the 57,3%.
