Abstract

The composition and structure of vegetation is one of the parameters that must be considered in forest planning activities. It can also be defined that the structure of vegetation as a result of spatial planning by the components of the stand and the life form of the vegetation which is described through the conditions of diameter, height, distribution in space, canopy diversity, and species continuity. In order to be able to withstand the occurrence of landslides, especially those in sloping areas, it is very important to analyze the vegetation to determine the composition and structure of vegetation types so that the forest is maintained (Fahrul, 2007). The purpose of this study was to determine vegetation in the existing area around the landslides in Palopo city. Research methods. The method of determining plots is purposive sampling, to find out vegetation and tree classification based on the growth rate of the method, namely by making observation plots and placing them by census at the top of 12 landslide points with a size of 20 m x 20 m for trees, 10 m x 10 m for poles, 5 m x 5 m for saplings and 2 m x 2 m for seedlings. The results obtained for the growth rate of trees found 35 species with the highest IVI Litsea sp 95.94%, the growth rate of poles found 28 species with the highest IVI Litsea sp 71.15%, the growth rate of saplings found 62 species with the highest IVI Cinnamomum camphora 45.62 %, and the level of seedlings found 51 species with the highest IVI Nephrolepis cordifolia 40.78%. The biodiversity index found a sapling growth rate with the highest H' value of 3.41 in the high species diversity category. Likewise the highest evenness index on saplings with an E' value of 0.59 is in medium level of evenness.

Abstract

This study aims to determine the domicile distribution, find out the high-risk areas, and determine the risk of drug-resistant tuberculosis patients based on patient location in 15 districts of Makassar City from Tuberculosis register data of South Sulawesi Provincial Health Office in December 2017 – April 2019 period. Gen Xpert rapid or drug sensitivity examinations were used to define drug-resistant tuberculosis. The domicile location of patients was geocoded by maps in Google Earth and aggregated per area by using Kernel Density analysis using ArcView GIS 10.3 software. We found that drug-resistant tuberculosis cases tended to be clustered in the western part of Makassar City, an area with a fairly high population density. There were areas with the highest concentration of predicted cases as a high risk of transmission of drug-resistant TB, around the Bontoala District, Makassar District, and Mamajang District. Healthcare facilities located in hot spots area need to be equipped with molecular rapid test facilities and conduct drug sensitivity tests for all suspected tuberculosis patients. Further research needs to be carried out to determine the distribution of tuberculosis patients who are sensitive and resistant to drugs.

Abstract

Penelitian ini menganalisis perubahan tutupan lahan menggunakan Google Earth Engine (GEE). GEE menawarkan berbagai alat untuk memetakan dan mengukur tutupan lahan, sehingga memungkinkan untuk mendeteksi perubahan dari waktu ke waktu. GEE menggabungkan citra satelit, data geospasial, dan alat analisis otomatis untuk memahami sifat dinamis dari perubahan tutupan lahan, dan dapat digunakan untuk mendukung strategi pengelolaan yang efektif. Penelitian ini dilakukan di wilayah UPTD KPH Karossa. Dimana, illegal logging, pertambangan illegal, perkebunan kelapa sawit illegal, konflik areal serta permasalahan pada program transmigrasi yang belum memiliki pelepasan kawasan hutan terjadi di wilayah tersebut. Metode yang digunakan yaitu klasifikasi terbimbing (supervised classification) dengan algoritma Random Forest (RF) memanfaatkan bahasa pemrograman (JavaScript) yang merupakan salah satu metode machine learning yang disediakan GEE. Hasil klasifikasi penutupan lahan melalui platform GEE memiliki nilai uji akurasi sesuai dengan standar minimal yang dipersyaratkan, yaitu nilai overall accuracy 0.946 dan kappa 0.902. Sebanyak 14 variabel yang digunakan dalam manjalalankan proses klasifikasi terbimbing (supervised classification) tersedia dalam platform GEE. Penutupan lahan di wilayah kerja UPTD KPH Karossa mengalami perubahan yang sangat dinamis. Kelas vegetasi berubah menjadi kelas lahan terbuka dan kelas semak belukar. Begitupun dengan kelas semak belukar, berubah menjadi kelas vegetasi dan lahan terbuka. Kelas lahan terbuka berubah menjadi kelas semak belukar kemudian berubah menjadi kelas vegetasi. Hal ini dipengaruhi karena tingginya aktivitas perkebunan masyarakat diwilayah kerja UPTD KPH Karossa.

Abstract

Land-use changes result from changes in the human population, their activities, and social and environmental activities, which occur in a complex and dynamic manner. The change of forested areas to non-forested areas, also known as deforestation, is a land-use change. Deforestation influences land cover by creating a specific distribution pattern (fragmentation). Almost the entire forest has been fragmented into smaller areas, but the pattern of each of these forest areas is uncertain. As a consequence, it would be more challenging to control potential deforestation. Using the spatial metrics of Clumpiness index, Contiguity index, and Patch density, deforestation in one of the forest areas, namely the Ko'mara forest area, was carried out. This research was analyzed using GIS and Fragstat software in raster data format. The analysis results show that the spatial pattern of deforestation in this area has a clumped distribution, with a high level of patch contiguity and a low to medium level of fragmentation. This pattern represents the form of deforestation in the Ko'mara forest area in 2005-2010 and 2010-2015 was classified as Low Deforestation with a deforestation rate of <1%, but was classified as Moderate Deforestation in 2015-2019 because the value obtained was 1.1%.

Abstract

The Hydrologic Engineering System-River Analysis System (HEC-RAS) model is a model that can display water surface cross-sections in both 1D and 2D forms. That way, HEC-RAS can predict the amount of peak discharge that results in flooding. This study aims to see the distribution of flood areas in the Paremang Watershed as a basic form of mitigation activity for flood events. A flood disaster analysis was conducted using the HEC-RAS model. The HEC-RAS model data includes river water discharge data from the Soil and Water Assessment Tools (SWAT) analysis, which is an overlay of topography, land cover/use, soil characteristics and climate data from authorized agencies, and direct field observations. The results showed that the flood area was 2,722.38 ha, affected by high rainfall conditions, steep slopes accelerating water flow, and land cover dominated by rice fields, bushes and dry land agriculture. The condition increases surface flow, stimulating the amount of water discharged. This resulted in flooding in most of the downstream and middle areas of the Paremang Watershed in Luwu Regency. Therefore, mitigation in the form of land use planning is needed. The plan is led by the Ministry of Agrarian Affairs and Spatial Planning, which includes other sectors ranging from forestry, agriculture, fisheries, tourism, and public works. This could support in developing policies ranging from forest rehabilitation, social forestry, community forests, expansion of agroforestry patterns, ecotourism development, and flood mitigation such as technical buildings.

Abstract

Balla Lompoa Ri Galesong, known well as the traditional house of the Takalar Regency, South Sulawesi, has become a historical building in Indonesia.  Nowadays, it still functions as a residence for the royal family, a repository for historical artifacts, and a venue for annual cultural performances. Maintaining and protecting buildings from damaging factors is crucial to maintaining their life and function. This research focuses on detecting the damage characteristics of wooden parts of buildings, identifying biological deterioration agents, and assessing the level of infestation. Data collection uses the visual detection method. The results showed that the activities of biodeterioration agents, namely subterranean termites (Microcerotermes serrula), drywood termites (Cryptotermes), powder-post beetles, wood-staining fungi, and wood-decaying fungi found on pillars, windows, doors, walls, floors, and ceiling. Most pillars are targets of attacks by wood-destroying organisms, characterized by the highest attack intensity (70.13%) and the moderate category in the degree of attack (50–74). Understanding and mitigating the damage to historic buildings is critical for implementing effective preventive measures. Keywords: Balla Lompoa Ri Galesong, biodeterioration agents, cultural heritage, wood biodeterioration

Abstract

The increasing population has led to a growing demand for non-agricultural land, resulting in land use conversion. Often, land needs extend to areas designated as protected, such as riverbanks, road margins, and spring borders. The riverbank boundary is defined as the outer limit of a river channel designated as the river protection boundary. In recent years, the Mamasa Sub-Watershed (Sub DAS Mamasa) has experienced forest conversion into plantations and agriculture, impacting the hydrological function of the area. On the other hand, there is a lack of data explaining the functions of riverbank areas in the Mamasa Sub-Watershed. The objectives of this research are (1) to understand the land use along the riverbanks in the Mamasa Sub-Watershed and (2) to identify the conformity of land use along the riverbanks in the Mamasa Sub-Watershed with the Regulation of the Republic of Indonesia No. 38 of 2011 concerning Rivers. The results of the land use identification along the riverbanks in the Mamasa Sub-Watershed include secondary forests (430.95 ha), primary forests (386.64 ha), mixed gardens (321.81 ha), rice fields (218.67 ha), fallow fields (179.25 ha), traditional vegetable gardens (194.65 ha), village settlements (51.83 ha), urban settlements (5.68 ha), coffee plantations (7.23 ha), cocoa plantations (17.93 ha), pine forests (59.60 ha), roads (23.51 ha), reservoirs (1.55 ha), shrublands (131.59 ha), bushes (28.94 ha), home gardens (18.88 ha), rock/sand expanses (3.73 ha), horticultural fields (9.86 ha), other open areas (2.37 ha), and an airport (0.41 ha). The appropriate land use along the riverbanks according to Regulation 38/2011 concerning Rivers is 1,043.01 ha (49.78%), while the non-compliant land use is 1,052.09 ha (50.22%).
