Abstract

ABSTRACT The research area is included in the Malili Sheet, located in the Bone-Bone River Sub-watershed, Bantimurung District, Bone–Bone District, Luwu Regency, South Sulawesi Province with coordinates 120o29'00” east longitude – 120°34'00” east longitude and 2°30'00 “LS – 2°37'00” South. In general, this study aims to determine the causes of flood hazards by using the field survey method and data management with geographic information systems (GIS), Analytical Hierarchy Process (AHP) weighting, and potential flooding in the research area. The parameters used in making the map are slope maps, elevation maps, land use maps, distance maps to rivers, and rainfall maps. The results of the flood hazard map showed the highest hazard level of 7.32% of the research area or 5.56 km2. But the map is dominated by a low hazard level of 73.01% of the total area of 55.49 km2. Based on field observations, several factors that can cause flooding at the research location are the results of landslides in the river body, which can cause river silting.   ABSTRAK Daerah penelitian termasuk dalam Lembar Malili yang terletak di Sub-DAS Sungai Bone-Bone, Kecamatan Bantimurung, Kabupaten Bone-Bone, Kabupaten Luwu, Provinsi Sulawesi Selatan dengan koordinat 120o29'00” BT – 120°34'00” Bujur Timur dan 2°30'00 “LS – 2°37'00” Selatan. Secara umum penelitian ini bertujuan untuk mengetahui penyebab bahaya banjir dengan menggunakan metode survei lapangan dan pengelolaan data dengan geographic information systems (GIS), pembobotan AHP (Analytical Hierarchy Process) dan potensi banjir di daerah penelitian. Parameter yang digunakan dalam pembuatan peta adalah peta kemiringan lereng, peta elevasi, peta tata guna lahan, peta jarak ke sungai, dan peta curah hujan. Hasil peta kerawanan banjir menunjukkan tingkat kerawanan tertinggi sebesar 7,32% dari luas daerah penelitian atau 5,56 km2. Tetapi peta tersebut didominasi oleh tingkat bahaya rendah sebesar 73,01% dari luas total 55,49 km2. Berdasarkan observasi lapangan, beberapa faktor yang dapat menyebabkan banjir di lokasi penelitian adalah akibat longsoran di badan sungai yang dapat menyebabkan pendangkalan sungai.

Abstract

The need for built-up areas in the City of Makassar has continued to increase in recent years due to the rate of population growth. The reduced availability of land in the center of Makassar City causes the demand for built-up areas to shift to suburban areas. In this shift, there is a process of changing the use of non-built-up land into built-up areas. Reduced use of non-built-up land in suburban areas can cause environmental damage. The aims of this study are: (1) to predict changes in land use in Makassar City until 2034, (2) to develop directions for controlling built-up areas. The method used is visual interpretation (digitize onscreen) to obtain land use maps for 2012 and 2022, the Land Change Modeler (LCM) model to predict land use change in 2034 by comparing two land use scenarios, namely Without Scenario (TS) and Restriction Built-up Area (PAT). Scenarios that are able to reduce the rate of development of built-up areas will be chosen as directions for spatial use until 2034. The results of this study show the same pattern of land use change in the two scenarios used, namely only settlements, built-up land and open land that experience an increase in area during the analysis period. However, this scenario differs in terms of the extent of change. In the TS scenario, settlements increase by 706 ha (34%), built-up land by 272 ha (13%) and open land by 61 ha (3%). This increase reduced the area of paddy fields by 425 ha (20%), mixed gardens by 228 ha (11%), ponds by 222 ha (11%), shrubs by 69 ha (3%), forest by 52 ha (3%) and water bodies by 44 ha. (2%). Whereas in scenario 2, the increase in settlement area is only 265 ha (31%), 114 ha (13%) built-up land and 44 ha (5%) open land, so that the decrease in the area of other land uses is also small, namely rice fields 186 ha (22 %), ponds 109 ha (13%), mixed gardens 88 ha (10%), shrubs 21 ha (2%), ponds 12 ha (1%) and forest 7 ha (1%). The PAT scenario proved to be more effective in restraining the rate of development of built areas so that it was chosen as the direction for controlling built areas in Makassar City until 2034.

Abstract

Nutrients are the most important thing in plant growth, where one of the nutrients in the soil is nitrogen, phosphorus, and potassium. Without nutrients in the soil, the growth process in plants will also experience obstacles. This study aims to determine the percentage of NPK nutrient content in the soil and to provide fertilizer recommendations for nutrient-deficient soils in Metun Sajau Village, Bulungan, North Kalimantan. This research method uses a random sampling technique based on randomization rules, namely, there is no limit to the number of soil samples to be selected by using GPS to determine the sampling point and by using a mineral drill to take soil samples at each location. All sampling points have the same probability and are independent of each other. Soil sampling will be carried out by taking the top layer of topsoil with a depth of about 0-30 cm by taking 12 soil sample points. And with the provisions of 0.5-3 Ha / 3 points of soil samples. Then the soil samples that have been taken are composited and then labeled. Soil samples taken from the field will then be analyzed and tested in the University of Borneo Tarakan soil laboratory for analysis. The results showed that the recommended fertilization recommendations were Urea, SP-36, KCL, and 15-10-12 compound fertilizer with doses according to plant age and class suitability conditions on the land.
