Abstract

Forests are crucial in absorbing carbon dioxide (CO2) from the atmosphere through photosynthesis and storing the carbon in its biomass. This research aimed to assess the potential for CO2 absorption of forests around landslides along the Trans Palopo-Toraja highways. This research employed a destructive sampling to measure understorey and litter biomass. Furthermore, it measured the biomass of understorey plants and litter with a destructive method. The 12 measurement plots were purposively placed on the landslide points to represent various vegetation conditions. The results revealed the presence of 77 plant species, totaling 554 individuals on the measurement plots. Plot 4 and Plot 1 showed the highest and lowest carbon absorption potential at 790.39 tons/ha and 199.63 tons/ha, respectively. The estimated average absorption of 12 plots was 461.75 tons/ha. Tree-level vegetation had the highest carbon absorption value due to its bigger diameter and CO2 absorption capacity than saplings and poles.

Abstract

The inflitration capacity is the soil’s ability to accommodate water that seeps into the soil, reducing surface runoff that will cause flooding, such as in the downstream area of Palopo city. This study aimed to determine the influence of dominant vegetation and soil physical characteristics on infiltration in the upstream area of the Latuppa Sub-Das, Mungkajang District, Palopo city. Data collection was carried out by direct observation in the 2yumnaunanda588@gmail.com field in a purposive manner in 10 plots, which represent the condition of vegetation in the upstream area of the Latuppa watershed, and each plot consisted of 3 replications to observe infiltration and soil samples. The data were analyzed via the rational method, the Horton method, and vegetation index analysis. Additionally, the data were analyzed via simple linear regression and multiple regression analysis to determine the influence of the dominant vegetation and physical characteristics of the soil on the infiltration capacity. The highest infiltration capacity was found in plot 10, with an infiltration capacity of 107.5 mm/minute (6,450 mm/hour) and an average infiltration rate of 0.4 mm/minute (24 mm/hour). The dominant vegetation cover is Cananga odorata, with a vegetation index value of 78.41%. Plot 10 has a height of 362.79 masl, a gentle slope, a crumbly soil structure, a clay sand texture, a very high soil density and 2.10% organic matter. Based on observations and data analysis, the factors that influence the infiltration capacity in the upstream area of the Latuppa subwatershed are vegetation conditions, altitude, slope and physical properties of the soil.

Abstract

The distribution of mangrove plants is influenced by various factors, including the physical characteristics of the soil. The study was conducted to determine the physical characteristics of the soil in the mangrove ecosystem in Bone Bay, Palopo City. Soil sampling was performed using the purposive sampling method in five points with three replications based on the equations of growth and density of mangrove vegetation. Physical characteristics of the soil sample, including texture, color, permeability, bulk density, and soil porosity, were analyzed in the laboratory. The results showed that the dominant soil textures were squirming and sandy loam. The dominant soil color was very dark gray. Soil permeability is high and belongs to the fast criteria, with the highest value of 20.0 cm/hour at the fourth depth point of 0-30. The highest bulk density at the fourth depth point is 31-60 cm, with a value of 0.81 gr/cm3. At the same time, the porosity of the soil is classified as a high or good criterion, with the highest value found at the third depth point of 0-30 cm with a value of 77%. In the future, soil physical characteristics data can be used as preliminary information or databases for the government to organize and preserve mangrove forests.

Abstract

Upaya untuk meningkatkan produktivitas adalah dengan memberikan pakan yang sesuai dengan kebutuhannya. Pakan dengan kualitas dan kuantitas yang cukup, sangat dibutuhkan untuk mendukung pertumbuhan dan produksi. Total produksi dalam usaha perikanan sekitar 80% nya keluar untuk penyediaan pakan saja. Kondisi ini tentu menjadi kendala bagi kelompok Tani POKDAKAN Bamba, karena biaya pakan ikan yang mahal. Sehingga upaya untuk meminimalisir biaya adalah dengan memanfaatkan sumber pakan yang ada disekitar tempat tinggal kelompok POKDAKAN Bamba. Salah satu sumber pakan yang bisa diolah adalah limbah sagu. Limbah ampas sagu selama ini tidak dimanfaatkan oleh masyarakat. Padahal limbah ampas sagu merupakan sumber protein nabati yang dapat diolah menjadi pakan ikan berbentuk pellet. Metode pelaksanaan PKM yaitu sosialisasi dan koordinasi kelembagaan, penyusunan modul, penyuluhan dan pelatihan, pemberian alat TTG dan pendampingan kelompok. PKM di laksanakan di Desa Walenrang, Kecamatan walenrang, Kabupaten Luwu, Provinsi Sulawesi Selatan. Jumlah peserta yang hadir sebanyak 23 anggota kelompok POKDAKAN. Hasil dari PKM ini adalah kelompok Tani POKDAKAN Bamba memiliki keterampilan dalam mengolah limbah sagu sebagai pakan ikan dengan menggunakan mesin pembuat pakan, mandiri dalam menyediakan pakan ikan yang mereka budidaya dan mengurangi biaya pakan. Kesimpulan dari kegiatan ini adalah kelompok POKDAKAN Bamba mampu mengurangi biaya pembelian pakan karena mampu membuat sendiri dari bahan-bahan yang tersedia di lingkungan mereka. Efforts to increase the productivity of fish farming is to provide feed that suits their needs. Feed with adequate quality and quantity is needed to support the growth and production of fish farming. About 80% of total production in the fishery business goes out to provide feed only. This condition is certainly an obstacle for the POKDAKAN Bamba Farmer Group, due to the high cost of fish feed. So the effort to minimize costs is to utilize food sources around the POKDAKAN Bamba group's residence. One of the feed sources that can be processed is sago waste. So far, sago pulp waste has not been used by the community. Even though sago pulp waste is a source of vegetable protein that can be processed into pelleted fish feed. The methods for implementing PKM are socialization and institutional coordination, preparing modules, counseling and training, providing TTG tools and group mentoring. The results of this PKM are that the POKDAKAN Bamba Farmer Group has the skills to process sago waste as animal feed using a feed making machine, is independent in providing food for the fish they cultivate and reduces feed costs. The conclusion from this activity was that the POKDAKAN Bamba group was able to reduce the cost of purchasing feed because they were able to make their own from ingredients available in their environment.

Abstract

Kasa is one of the important species among 120 species in the genus Castanopsis (Fagaceae), which thrives in secondary and primary lowland forest areas up to 1000 m above sea level. This plant species exhibits tolerance to full sunlight. The objective of this study is to assess the regeneration potential of Kasa (Castanopsis acuminatissima Blume) in the Kalaena Nature Reserve, Indonesia. The research plots consisted of two 50 m x 50 m plots, with a nested 10 m x 10 m subplot placed using purposive sampling. The findings regarding the regeneration potential of Kasa in the Kalaena Nature Reserve revealed varying numbers of seedlings, saplings, poles, and trees. The regeneration potential of Kasa is influenced by the growth stages of seedlings and trees. During the seedling phase, the regeneration potential of Kasa is classified as very good. However, the density of trees, although in the productive category, is low due to environmental factors and the characteristics of the parent tree. Conversely, the sapling and pole phases exhibit very poor regeneration potential. In plot 1, there were 1964 individual seedlings, 6 individual saplings, 4 individual poles, and 21 individual trees. Meanwhile, plot 2 recorded 844 individual seedlings, 5 individual saplings, 1 individual pole, and 18 individual trees. The growth of Kasa in both plots displayed a clustered pattern.

Abstract

Landslides are natural hazards driven by both triggering and controlling geological factors. Comprehensive assessments of landslide-prone areas and their associated volumes are essential for understanding present-day risks and informing effective mitigation strategies. This study investigates landslide vulnerability in Battang and Battang Barat Villages, Palopo City, with a focus on geological conditions, landslide extent and volume, and spatial vulnerability using Digital Surface Model (DSM) analysis. Field data were collected from 14 landslide sites through GPS mapping and aerial surveys using a DJI Mavic 2 drone. The data were processed using Agisoft Metashape Professional to generate DSM and orthomozaic imagery, while spatial analyses were performed in ArcGIS 10.5. Landslide area and volume calculations were conducted using PCI Geomatica. The analysis revealed that the average landslide-affected area is 0.30 hectares, with an estimated average volume of 5,195.58 m³. The dominant soil types include Dystric Fluvisols, Humic Ferralsols, and Ferric Acrisols, underlain by geological formations such as Lamasi Volcanic Rocks, the Latimojong Formation, and Palopo Granite. Slope gradients range from flat to steep, and land cover is primarily composed of scrub and dryland forest. The study classifies landslide vulnerability into medium and high categories, providing critical insight for site-specific hazard mitigation and land-use planning.
