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.

Abstract

Rice (Oryza sativa) production in Indonesia has declined due to low iron (Fe) availability in alkaline soils, impacting plant growth and yield. Integrating Fe seed coating with sago (Metroxylon sp.) waste organic fertilizer may improve Fe availability and soil quality, offering a potential solution to enhance rice production. Our objective was to examine the effects of Fe seed coating and the incubation of sage waste organic fertilizer on rice growth. The study employed a factorial 2-factor randomized block design. The first factor was the concentration of Fe seed coating, with four levels: 0 g, 55 g with 2.5 g gypsum, 110 g with 5 g gypsum, and 275 g with 12.5 g gypsum. The second factor was the incubation time of organic fertilizer, with four durations: 0 weeks, 3 weeks, 4 weeks, and 5 weeks. The interaction between Fe seed coating and sago waste organic fertilizer incubation significantly impacted plant height (153.33 cm), leaf color chart scale (4), chlorophyll a (254.73 μmol.m-2), chlorophyll b (96.90 μmol.m-2), with the most notable effects observed at a Fe seed coating concentration of 275 g with 12.5 g of gypsum and a 5-week incubation period. The application of Fe seed coating at a concentration of 275 g with 12.5 gypsum, combined with a 5-week of sago waste organic fertilizer, effectively enhances plant height, chlorophyll a, chlorophyll b, and the leaf color chart scales.

Abstract

The small value of erosion on a land is sometimes ignored even though it can sometimes have an effect on a land. Industrial plantation forests (HTI) are present as a government effort to combine timber production and forest rehabilitation. However, the problems faced are low land productivity, decreased soil fertility due to erosion processes in the soil layer. The research hypothesis is that the use of a layered canopy, good soil infiltration will reduce the rate of erosion and surface flow. This research aims to study the amount of erosion in industrial plantation forests in Tompobulu District, Maros Regency. This research was conducted in January-February 2022 in Bahagia Hamlet, Bontomanurung Village, Tompobulu District which was carried out using the erosion plot method. Erosion plots were made in two stands in monoculture and agroforestry industrial plantation forest areas. The measurement results of the amount of flow rate in monoculture HTI is greater than agroforestry HTI which each has a surface flow, namely 113.86 m3/ha and 55.43 m3/ha. While the erosion rate in monoculture HTI is greater than agroforestry HTI, each of which has an erosion rate, namely in monoculture HTI of 0.19 tons/ha and agroforestry HTI of 0.06 tons/ha. The estimated value of annual erosion and tolerable soil loss (TSL) in each stand, namely monoculture HTI is 2.57 tons/ha/year and 4.69 tons/ha /year, while in agroforestry HTI respectively 1.45 tons/ha/year and 9.69 tons/ha/year. Each of the two stands produced estimates of annual erosion that were smaller than the tolerable soil loss (TSL). Good interception (use of layered canopy, vegetation with large leaf surface area) and good infiltration can reduce erosion and surface runoff.
