Abstract

The Banjarbaru administrative status has changed from an Administrative City to a City, and in 2022 become the Provincial Capital. Population growth and infrastructure/building development due to these changes may affect environmental changes. A significant increase in air temperature against its normal due to environmental changes can trigger climate change. Urban Heat Island (UHI) is a phenomenon recognized by the higher temperature conditions in urban areas compared to surrounding areas. UHI identification is known by calculating the difference in Land Surface Temperature (LST) values using remote sensing (satellite data). An increase in the value of LST in an area can trigger the appearance of UHI and make the environment less comfortable. The LST value is also related to population, vegetation, residential areas, and built-up land. Thermal Humidity Index (THI) is an index used to determine comfort level based on temperature and humidity conditions. This study aims to analyze spatiotemporal changes in UHI phenomena in the Banjarbaru area during three administrative status periods (1998 - 2022) and its effect on the comfortable index. This study uses Landsat satellite data (consist Visible, Near Infrared, and Thermal Bands) and Relative Humidity (RH) from 2 weather stations in Banjarbaru. The result shows that the distribution of UHI in the Banjarbaru City area increases around industrial areas, settlements, government centers, and along arterial roads that are open land without trees. In general, the Banjarbaru area experienced an increase in the comfort index. Initial conditions belonging to the comfortable and less comfortable classes changed to become less comfortable to uncomfortable, especially in the North Banjarbaru sub-district and around Syamsudin Noor Airport ( Landasan Ulin sub-district).

Abstract

Mining activities often cause environmental damage, such as landslides, floods and ecosystem changes. These activities include land clearing, top soil stripping, overburden stripping, coal excavation, coal transport and processing. It is necessary to have an activity as an effort to rehabilitate so that there is no sustainable environmental damage. Therefore topsoil storage must be carried out in order to return the post-mining area to green again. The consideration of replanting ex-mining areas uses a comprehensive environmental management strategy, especially in terms of handling nutrient-rich topsoil. Topsoil is peeled to a thickness of 0.5 – 1 meter using an excavator. Then it is stacked and stockpiled in a place that is safe from mining activities so that later it can be reused in reclamation activities. The purpose of this research is to obtain a technical design on the corner of the storage area to reduce the eroding impact of rain runoff or other mining activities. Where the method used is to calculate the erosion that occurs on each slope where the test is carried out with 4 different slope angles such as 20⁰, 25⁰, 30⁰ and 35⁰. After obtaining the erosion data, the researchers created an ideal design to reduce the impact by considering the balance aspects of the slope and the material itself. Where the recommended angle data obtained to reduce the eroding impact is 25⁰.

Abstract

Kegiatan dalam inventarisasi hutan salah satunya adalah pengukuran potensi volume tegakan. Penggunaan angka bentuk rata-rata sebesar 0,7 dianggap kurang tepat karena penggunaan satu angka bentuk tersebut merupakan rata-rata untuk semua jenis dan semua lokasi menghasilkan dugaan volume yang tidak akurat dan penggunaan satu angka bentuk untuk semua jenis dan semua lokasi menghasilkan dugaan volume yang tidak akurat. Tujuan dari penelitian ini adalah menganalisa besarnya angka bentuk pohon dari beberapa jenis meranti (meranti batu (Parashorea aptera), meranti merah (Shorea leprosula) dan meranti putih (Shorea agamii)) di hutan lahan kering sekunder PT Borneo Indobara Kabupaten Tanah Bumbu Provinsi Kalimantan Selatan. Pengumpulan data dilakukan secara survey menggunakan plot pengamatan berukuran 40 x 40 m sebanyak 5 plot dengan sampel minimal 30 sampel dan pengambilan sampel dilakukan secara purposive sampling yang berdasarkan kriteria. Hasil yang diperoleh yaitu angka bentuk pohon pada beberapa jenis meranti di areal PT Borneo Indobara sebesar 0,86.  Angka bentuk 0,86 lebih besar dari pada angka bentuk rata-rata yaitu 0,7.

Abstract

Recognizing the composition of forest ecosystems is important to maximize forest utilization and conservation. One of the steps that can be used is to identify the vegetation in the forest. Pandamaran Hill, which is located at an altitude of 275 meters above sea level, has a forest with conditions that are still rarely touched by humans so that identification of vegetation at that location is important. This study aims to analyze the distribution and identify plant species at the pole and tree growth levels located in Bukit Pandamaran KHDTK Mandiangin. The method used to determine sample points is based on purposive sampling method with line intercept method. The size of the sample plot in this study is based on the species area curve to determine the minimum sample plot to be made. The results of this study showed that the distribution of pole-level plants in the three locations was the type of Tampar Badak, Rukam, and Margatahan while the distribution of tree-level plants in the three locations was the type of Tengkook Ayam, Serai Putih, and Marsihung. The pole level in locations I, II and III for the highest INP value is the same type of Damar Kumbang. Similar to the pole level, the tree level at locations I, II and III the highest INP value was obtained by the Damar Kumbang species. Mengenali susunan komposisi ekosistem hutan penting untuk memaksimalkan pemanfaatan dan pelestarian hutan.

Abstract

Diameter-height relationship model is generally developed to facilitate the quantification of tree height at the individual level. However, the model’s reliability principally varies due to the influence of certain factors like site quality and type of species. Thus, a site species-specific model is recommended to support sustainable forest management. This study aims to evaluate the best-fit model for estimating the tree height of Shorea assamica in the secondary tropical rainforest, South Borneo. Data from forest inventory consisting of 1,440 tree diameter at breast height (DBH) and height measurements were used to evaluate five alternative models, i.e., Linear, Power, Exponential, Sigmoid, and Gompertz. These data were randomly split into two datasets, i.e., initial model development (1,009 trees) and model validation (431 trees). The model reliability was assessed and ranked using the coefficient of determination (R2), residual standard error (RSE), akaike information criterion (AIC), mean absolute error (MAE), and root means square error (RMSE). The results of the study obtained an average tree diameter of 42.8 cm with the inverval of 22-99 cm and a mean tree height of 16.6 m with the distribution of 11-31 m. The Power model showed the best fit to explain the relationship model between the diameter and height of the S. assamica with an R2 of 74% and an RMSE of 1.72 m. It indicated Power model could facilitate more efficient tree height estimation of S. assamica in the study site

Abstract

TOGA or family medicinal plants are plants with medicinal properties that are planted in home gardens. TOGA can provide health and economic benefits for residents. Based on observations in Kiram Village, so far the people of Kiram Village, especially the people of RT 01, have not used their yard land optimally. Only some village residents use their yard for planting TOGA and it is not optimal. Therefore, it is necessary to provide outreach, training and assistance for TOGA intensification to the Kiram Village community. The aim of this outreach and assistance activity is to improve the function of home gardens through the application of TOGA, empower the community with new knowledge and skills in TOGA cultivation and increase community knowledge of the benefits of TOGA for health. Methods: Activities carried out include outreach and counseling, training and mentoring, as well as monitoring and evaluation. After the counseling and mentoring activities, there was an increase in public knowledge regarding various types of TOGA, the use of TOGA and how to cultivate TOGA. The public also understands more about the benefits of TOGA for health. Before the community service activity was carried out, only three houses had their yards planted with TOGA, whereas after the activity there were 15 houses whose yards had been used by the community to plant TOGA.
