Abstract

Gunung Merbabu National Park (TNGMb) is a conservation area with a high level of biodiversity. Information on land cover is very important in making ecological management policies in conservation areas. Proven Remote Sensing technology produces precise information on land cover in a time and cost-effective manner. This study uses Landsat 8 imagery in TNGMb land cover classification process. Maximum Likelihood approach is used because it uses a probability calculation basis. A configuration matrix table between training data and reference data is made to test the accuracy of land cover classification. Reference data refers to Google Earth Pro high-resolution imagery. Results showed that the most extensive land cover type was secondary dryland forest with total of 23393 pixels classified as equivalent to 2113.54 hectares (34.5% of the total classification area. The open area, built-up area, and rice field/vegetable garden each have an area of ​​12.08 Ha; 11.02 Ha; and 170.96 Ha, of which part of the area is in enclaved areas within the TNGMb area. The accuracy test shows the Kappa Coefficient of 86.25%, User's Accuracy Average, Ground Truth Average, and Overall Accuracy respectively 89.62%; 85.42%; and 88.33%. Overall Accuracy shows that 88.33% of the total pixels represent each classification correctly.

Abstract

The potential for wood raw materials in Indonesia is very abundant, but the increasing need for processed wood as a building material makes it difficult to obtain sawn timber in large sizes and with quality, due to the increasingly limiting logging in natural forests. High quality wood is hard to find in the market, so it is necessary to combine low quality and high quality wood by engineering the product with an adhesive, one of which is glued laminated timber. This study aims to see the characteristics of the glued laminated timber of Acacia mangium and Shorea leprosula based on the arrangement of lamina and the weight of adhesive Styrofoam. The blocks used in this study were 120 cm x 5 cm x 3 cm in size with the adhesive composition used was 60% Styrofoam and 40% gasoline with an glue spread of 200, 220 and 240 gr / m2. Observations made to produce data that is, the moisture content obtained layer ranged from 4.14 to 8.86%, a density of 0.38 to 0.51 g / cm3, MOE and MOR ranged from 24.78 to 86.71 kg / cm2.

Abstract

Regional development has a tendency to minimize green open space and also remove the face of nature. The increasingly disharmonious relationship between humans and nature has resulted in ecological deterioration in the environment. Less land covered by trees causes the environment to become hot. The Lancang Kuning University Campus is one of the places of education in which the entire academic community, employees and other parties are located. In carrying out all campus activities, a comfortable environment is needed. The objectives are: to identify tree characteristics in the faculty environment; measuring the comfort level of the faculty environment. The objects this research are tree types. The equipment used is: thermohigro, camera, phi band, haga meter, roll meter, stationery. While the material used is thally sheet. Primary data taken in the field are tree data, temperature and humidity. The comfort index is categorized: comfortable, if it has a value of 21 THI 24; quite comfortable 24 THI 26 and not comfortable THI 26. There were 31 tree species with 472 trunks with an average diameter of 19 centimeters and an average height of 10 meters. The Temperature Humidity Index (THI) of all faculties is in the uncomfortable category.

Abstract

Lancang Kuning University Campus (UNILAK) is one of the campuses that has a fairly wide area and has enormous potential, especially related to the use of space whose potential has not been maximally utilized to support the Tridharma activities of higher education. The lack of land use is due to a more detailed inventory of land cover types that have not yet been carried out so that data and information related to existing land cover types are still very minimal. So it is necessary to identify the type of land cover and land cover characteristics at the Unilak Campus, to obtain information and data for further use. Land cover is the mention of biophysical appearance on the surface of the earth consisting of areas of vegetation, open land, built up land, water bodies and wetlands. One of the activities carried out for land cover data collection is land cover inventory activity using applications in the senses and GIS to collect data on land cover types in the study area coverage. Information on the types of land cover can be obtained from land cover data inventory activities through ground check activities or data collection on land cover conditions in the field.

Abstract

The Social Forestry Policy (PS) in the Perhutani working area has started a new beginning towards the current PS implementation. The issuance of regulation P.39 / 2017 was colored by various narratives / discourses from various actors decorating the journey of the policy issuance above. Using a narrative / discourse analysis approach, this study intends to explore the narratives used by parties in the policy process and those who receive the impact of SF policies. The research method used is descriptive qualitative analysis within-depth interviews with selected respondents proportionally (purposive sampling). The results of the study explain that the narrative of each party is different. The narrative brought by the pro to the policy is based on the condition of the forest and the social conditions of the community around the forest that have not been successfully improved, including the PHBM program that needs to be evaluated. The IPHPS scheme provides opportunities for access and higher profit sharing for the community to manage forests with low cover conditions (10%) and or social conditions that need to be addressed. Perhutani brought a narrative about the current regulation violating the previous regulation.

Abstract

TWA Sungai Dumai is a tourist forest area and ensuring the preservation of natural potential. However, there are problems that can disrupt the sustainability of it, including forest and land fires and conversion of land use to agriculture and oil palm plantations. Until now, there is no vegetation analysis using satellite imagery in TWA Sungai Dumai, so it is important to do so that can be managed sustainably. This study classification of vegetation density classes which are presented in the form of a vegetation density class map in it. This research uses Landsat-8 OLI / TIRS images from October 2017 and October 2020 which are processed to determine density class using Normalized Difference Vegetation Index algorithm. The vegetation density class with the highest area in 2017 was the vegetation density class (2380,832 ha or 66,819% of the total area), while the lowest area was the non-vegetation class (75,737 ha or 2,126% of the total area). The vegetation density class with the highest area in 2020 in TWA Sungai Dumai is dense vegetation density class (3205,039 ha or 89,950% of the total area), while the lowest area is non-vegetation class (1,637 ha or 0.046% of the total area)
