Abstract

This study aims to determine the diversity of soil fauna based on the landscape and soil depth in the cocoa plantation in Parenring Village, Lilirilau District, Soppeng Regency. This research was conducted from October 2020 to January 2021 located on a cocoa plantation in Parenring Village, Lilirilau District, Soppeng Regency. This research was conducted by taking soil samples using the Systematic Sampling (SYS) method, using monolithic soil sampling and disturbed soil samples. The observation of soil biota, hand sorting and microscopy were used. Based on the research results, soil samples in the back area had the highest soil biota diversity (H' = 1.32), followed by the valley area (H' = 1.29) and the middle area (H' = 1.18). Soil biota diversity is included in the medium criteria.

Abstract

The use of fish pond mud in improving soil quality is generally still not widely used. This study used various doses of pond mud to determine the effect of pond mud doses on the availability of N and Fe-soluble in Ultisol soil planted with mustard greens. The research was conducted in the Greenhouse in April - May 2022 with a Completely Randomized Design (CRD), five doses of fish pond sludge namely at doses of 0; 0.5: 7.5: 10; and 12.5% applied to Ultisol soil. The results showed that applying fish pond sludge significantly affected soil pH, N-NO3-, N-NH4+ and Fe-soluble. Soil pH decreases due to a reaction between water and Fe compounds that bind OH- and release H+. Whereas N-NO3-, N-NH4+, and soluble-Fe significantly increased due to chemical reactions that produced soluble salts which reacted with water. As for the soil parameters, the effect of pond mud decreases soil pH at all doses of addition of mud and increases N-NO3-, N-NH4+, and soluble-Fe Ultisol, with the best doses of M3 (equivalent to 1 kg mud + 9 kg of soil). There is a relationship between the chemical properties of the soil and the fresh weight of the plants, as evidenced by the increase in the wet weight of the mustard plants.

Abstract

To optimize Mamasa coffee production, a land use model that is appropriate to its designation is needed. The actual coffee area in Mamasa Regency reached 33,589.79 ha with a total of 20,980 farmer heads of households. This means that a large number of Mamasa people depend on Mamasa coffee. Analyze the land suitability of Mamasa coffee in relation to the regional hierarchy based on the availability of coffee supporting facilities in Mamasa Regency. Data analysis used the land suitability analysis method combined with a scalogram, to see contextually the process of intensification and development of Mamasa coffee supporting facilities. The results of this study indicate that most of the land for the business of managing Arabica and Robusta coffee plants is dominantly constrained by the physical conditions of the area where around 84.5% of the land is not suitable (N) with dominant slopes with erosion hazards (eh), root media (rc) and water availability (wa) in several open locations. In addition, the availability of coffee supporting facilities in Mamasa Regency is dominant in hierarchy 3 of 88%, while hierarchy 2 is only 9% and hierarchy 1 is 3%. This means that the facilities in Mamasa Regency in order to support coffee development related to processing facilities to marketing are still minimal. The Government of Mamasa Regency needs to pay attention to the improvement of coffee supporting facilities, especially in areas that are suitable land for Mamasa coffee, so that the intensification of coffee production in the upstream can be optimized and increased marketing in the downstream.

Abstract

Indonesia is characterized by a diverse topography and low to very high rainfall intensity.  In addition, the population density in fertile Indonesian hilly areas is also increasing.  These conditions translate to high potential for landslide hazard in Indonesia with threats of loss ranging from economic, social, to fatalities.  One of the areas with a high level of landslide hazard is Padalarang Subdistrict, West Bandung Regency, West Java Province.  The purpose of this research is to identify the landslide hazard in Padalarang Subdistrict, West Bandung Regency.  Geographic Information System Analysis was used in this study by using an overlay technique presented on the map.  The analytical method used was a survey-exploratory analysis with descriptive analysis techniques.  The results showed that the landslide hazard in Padalarang Subdistrict could be divided into three categories; having landslide hazard in the north, having landslide potential in the north to the west and southeast, and having no landslide hazard in the central to southern parts which are alluvial plains.  Analysis of the landslide hazard in Padalarang Subdistrict provided a spatial picture so that it could be potentially employed to be part of disaster mitigation to minimize material and non-material losses.

Abstract

Cutting slopes and backfilling land to make land plots for housing is a common practice in Indonesia.This study aims to identify the impact of cutting slopes and backfilling for the construction of residential plots in Imogiri Subdistrict, Bantul Regency, Yogyakarta Special Province. The study employed a field survey at the study site determined by purposive sampling method to find and evaluate the existing condition. Data was also obtained from literature studies and interviews with local communities. Data analysis was carried out in a spatial qualitative descriptive manner, using a geographic information system approach, with the help of ArcGIS 10.8 Software. The results showed that cutting slopes and backfilling have negatively impacted the environment and local communities. In the backfill process, it is necessary to strengthen the supporting slopes of the piled-up soil, control the water content and compact the soil properly to maintain slope stability and prevent a decrease in soil volume. In addition, it is necessary to periodically monitor the condition of the slopes and the surrounding environment to avoid the possibility of other negative impacts.

Abstract

The Palopo City West Ring Road is included in the Malili Sheet which is in Salobulo Village, Wara Utara District, South Sulawesi Province with coordinates 2º59'32.10” - 2º58'41.10”S and 120º10'34.51” - 120º10'40 .49” East. This study aims to determine the potential for landslides based on rock characteristics and slope geometry using the exploratory method, namely conducting research directly in the field and laboratory testing. Data acquisition was carried out at 5 observation stations which indicated the potential for landslides to occur. The data obtained are rock characteristic data including, rock type, fresh color and weathered rock color, rock texture and rock structure, as well as sampling, while the slope geometry data collection includes, height and slope of the slope, as well as observing other supporting factors namely, the degree of weathering, the presence of joints, surface runoff and the condition of the land vegetation.The results of data analysis show that the Palopo City West Ring Road has the potential for landslides which are influenced by several causal factors, namely, the steep slope of the slope, dominated by basalt rock which has undergone a weathering process with a high level of weathering at stations 2, 4 and 5 and the level of weathering moderate at stations 1 and 3. In addition, the presence of joints at stations 1 and 2 is a supporting factor for the potential for landslides to occur at the study site.

Abstract

The tropical climate condition of Baubau City which is located at 5°21'- 5°30' South Latitude 122°30' - 122°45' East Longitude causes the Kota Baubau Region which describes the tropics to experience more intensive weathering. Most of the landslides that occurred in Baubau City were in areas with unstable geological conditions and were often triggered by heavy rains that exceeded the highest point. This study aims to determine the causes of landslides, types of landslides, and countermeasures. In this study, measurements of slope geometry were carried out which included slope height and slope angle, testing rock and soil samples at the research station, as well as observing other supporting factors. The results of the study show that 3 stations have avalanche-prone zones. The causes of landslides are slopes with a slope angle of > 400 at station 1 of 530, station 2 of 410 and station 3 of 610, rainfall in the study area reaches the highest point of 714 MM, human activities such as dredging under the slope and construction of shaft roads cause slope instability and cause hazards such as landslides and vibrations. The types of avalanches at stations 1 and 2 are avalanches, while at station 3 the slides and falls are viewed from the geometry of the slopes processed by Autocad, the appearance of the research station and the results of the geostudio simulation show the shape of the slip plane with a FoS value of <1.07. Based on the results of research at 3 research station points, there is a potential for landslides to occur. The countermeasures methods used are structural mitigation, building of cliff reinforcement walls, surface soil stripping and increasing slope stability, namely changing the slope geometry. Non-structural mitigation, namely by providing information to the BPBD and the community regarding landslides.

Abstract

Soil has an important role "in agriculture for the growth and production" of plants. The combination of organic and inorganic fertilizers can increase crop productivity and improve soil quality on land so that it can be used sustainably. One of the potential plants that can be used as a basic ingredient of organic fertilizer is red onion. This study aims to determine the effect of red onion liquid organic fertilizer on changes in soil chemical properties and plant growth. This research was conducted using a factorial randomized block design (RBD) with 2 factors. The first factor is the dose of organic fertilizer and the second factor is the dose of inorganic fertilizer. Parameters observed were pH, C-Organic, N, P, K, tuber weight, plant fresh weight, number of leaves and plant height. The results showed that red onion organic fertilizer can lower soil pH and increase soil C-Organic, N, P and K. The combination of the D1KB2 treatment (50% basic fertilizer + 15,000 ppm red onion waste) gave the best results in increasing soil organic C, Phosphate and Potassium. Conclusion. The interaction of inorganic fertilizers and red onion liquid organic fertilizer had a significant effect on tuber weight and plant wet weight, and had no significant effect on plant height and number of leaves.
