Abstract

Land use that is not based on its capacity will has impact on land quality decreasing. This will lead to the emerging of critical land. This study aimed to analyze the critical level of forest area in the Pengabuan watershed. Critical land analysis was based on the Regulation of the Director General of Watershed Management and Social Forestry Number P.4/V-SET/2013. There were 4 parameters used, namely: land cover, erosion hazard level, slope and management aspects. Land cover was the main parameter in determining critical land because it had the largest weight. Geographic Information System (GIS) and remote sensing technique were used in data processing and analyzing in order to determine the critical level of land. The results showed that 50.58% of the land in the Pengabuan watershed forest area was classified as moderately critical (95,030.7 ha). Land with potentially critical criteria covering an area of 17,804 ha (75.19%) dominated forest areas within protected areas. Approximately 2.71% (4,457.6 ha) of the forest area with open land cover from forest areas outside protected areas was categorised as higly critical land.

Abstract

Degraded land due to brick industry, piling material, and coal mining activities are widely covered the area of Kebon IX Village, Sungai Gelam Subdistrict, Muaro Jambi District. This service activity was aimed at encouraging collective action by the village community of Kebun IX to apply citronella cultivation and processing technology in order to rehabilitate their land as well as develop productive economic businesses as a substitute for their old businesses that were not environmentally friendly. The method used was the combination of Participatory Rural Appraisal (PRA) and collective action model in promotion strategy and technology adoption. Through counseling, training and demonstration plots, four types of integrated businesses, including cultivation, processing and utilization of citronella by-product, have been successfully developed in Kebon IX Village. Citronella plants at aged 6‒8 months produced leaves at a price of IDR 500/kg and after 3 months can be harvested again. One clump of citronella plants can produce 1.5 kg at the first harvest and increase to 2.0 kg after the next harvest. One hectare of land can contain 1000‒1500 clumps of citronella plants. Citronella plant soil costs IDR 250,000/L, the residue of the distillation can be used as animal feed (IDR 150/kg) or used as trichocompost (IDR 1,200/kg). Trichocompost is also needed as organic fertilizer for the continuity of citronella cultivation. The integration of citronella plants cultivation and processing industry has a positive impact on land reclamation efforts as well as to empower the community's economy.

Abstract

Plant biomass is a carbon storage. The amount of biomass depends on the vegetation. This study aimed to analyze and predicted the above ground biomass stock in KPHP Unit X Tebo Timur. Regression analysis was used by correlating the biomass value from field measurement and the NDVI value from Landsat 8 imagery. Some of the regression equations tested were: linear, exponential, quadratic and rank. The best regression equation is used to estimate the biomass stock in KPHP Unit X Tebo Timur. The best model used to estimate above ground biomass stocks based on the NDVI value in East Tebo KPHP is quadratic with the equation Y = 574.05 ((NDVI) 2) - 17.24 (R2 = 85.5%). The analysis results showed that the above ground biomass stock in KPHP Unit X Tebo Timur was 9,695,091.39 tons.

Abstract

Bukit Tiga Puluh National Park is one of the important Nature Conservation Areasin central Sumatra because it has a variety of protected flora and fauna. The aim of this research was to observe the rate of change of land cover in the period 2002-2016 in Bukit Tiga Puluh National Park. The research used remote sensing methods by utilizing satellite imagery data to generate land cover data. This study used the classification of supervised images, where the image classes are self-defined based on field data in the form of coordinate points marked with GPS. The study found that land cover has changed from 2002-2016, where thearea of primary forest has decreased 5.422,80 hectares or with average rate 387,34 hectares/year, secondary forest had an increase of 103,00 hectares or with average rate of 7.35 hectares / year, open land increased 2,243.13 hectares or at an average rate of 160.22 hectares / year, dryland agriculture increased 1,929.69 hectares with an average rate of 137, 83 hectares / year, dryland farming mixed with shrubs increased 641.32 hectares or with an average rate of 45.80 hectares / year, and shrubs increased 505.66 hectares or with an average rate of 36.11 hectares / year. The results of the classification in the management zone, the core zone is dominated by primary and secondary forests while in the jungle zone there is a closure other than forests such as agriculture, shrubs and open land as much as 0.05%.

Abstract

Granting legal access to PT. REKI in ex. PT. The Asialog concession area in 2010 was marked by resistance accompanied by violence and claims by community groups (claimer). Conflict resolution with the Forestry Partnership approach resulted Forestry Partnership Recognition and Protection (Kulin KK) agreements for 79 heads of households who were members of 4 (four) groups. The question of this research is how the perceptions and participation of Kulin KK holders and the relationship between the two variables. The objectives of the study are to analyse the perceptions and participation and the relationship of its variables. This research is descriptive with a quantitative approach. The sampling technique used the census method with many respondents and 75 holders of legal access to Kulin KK. Perception and participation analysis and categorisation use 3 (three) point Likert scale and the score interval equation. The analysis of the relationship between perception and participation variables uses the Spearman correlation analysis. The results showed that the public perception of the provisions of the Forestry Partnership scheme was in the high category of 96% and 4% in the medium category, while the level of community participation was in the high category of 36%, 24% medium and 40% low. Perception and participation are negatively related.

Abstract

Biomass calculations are useful for knowing the amount of carbon stored in a forest ecosystem and essential steps to mitigate global warming and climate change. Restoration activities at PT Alam Bukit Tigapuluh (PT ABT) have indirectly made efforts to absorb carbon dioxide (CO2). This study aimed to analyze and measure carbon storage as well a model and map carbon storage at PT ABT. The method used the survey method of species, diameter at breast height, and vegetation height with a plot size of 20mx20m. The research conducted to analyze carbon storage and build a regression model. The results showed that the average carbon storage of the 30 plots was 259.32 tons/ha and the estimated carbon storage is 5,496,233 tC. The best regression model’s modelling result are Y = -817 + 331.5 MSRVI with the correlation of determination being 76.40%. The distribution of carbon storage in PT ABT is divided into 5 classes, namely, non-vegetated class (<0 tons/ha) of 57 ha, low (0-112.55 tons/ha) of 291 ha, medium (112.55-225.11 tons/ha) covering an area of ​​2,059 ha, high (225.11-337.67 tons/ha) covering an area of ​​18,533 ha and very high (>337.67 tons/ha) covering an area of ​​1,256 ha.

Abstract

Kaji Banding Dampak Ekologi Pengelolaan Hutan Adat dengan Tingkat Pengelolaan Berbeda dilakukan di Hutan Adat Rio Peniti (KUPS kelas biru), Desa Lubuk Bedorong dan Hutan Adat Imbo Larangan Pematang Kulim Inum Sakti (KUPS kelas emas) Desa Temenggung. Penelitian ini menggunakan responden 80 orang dengan masing-masing HA 40 responden. Data primer yang dikumpulkan yaitu aspek ekologi dengan metode wawancara menggunakan panduan instrumen kuisioner dan wawancara mendalam serta observasi langsung. Analisis dampak ekologi dilakukan dengan dengan metode Importance Performance Analysis (IPA). Dampak pengelolaan hutan adat terhadap ekologi kedua HA memiliki persepsi positif terhadap indikator ekologi ini terlihat kesesuaian antara nilai kepuasan dengan nilai kepentingan tinggi yaitu 95% untuk HA Rio Peniti dan 96,4% untuk HA Imbo Larangan Pematang Kulim Inum Sakti.
