Abstract

This research aims to find out; 1. Land quality and characteristics, 2) Land suitability level. Using a GIS-based purposive sampling method, overlapping land use maps, slope maps, soil maps and landform maps. Using field and laboratory analysis data with data analysis techniques, namely matching. The research results show that; 1. The characteristics of the land in the Kaonisik watershed are that it is in a rather dry climate, with moderate air temperature; rooting media for good to obstructed soil drainage; clay to sandy soil texture; medium-deep effective depth; nutrient retention for medium-high soil CEC; Neutral soil pH; available nutrients for P2O5(available P) high-very high; K2O low-very low; N-total 0.06-0.22; Potential mechanisms for slopes from flat, sloping, slightly sloping/sloping, steep and very steep; erosion hazard none-moderate; There isn't much surface rock. The level of land suitability obtained is four classes, namely verysuitable (S1), quitesuitable (S2), marginallysuitable (S3)

Abstract

Extreme rainfall that often occurs in South Sulawesi is caused by high rainfall intensity. Rainfall patterns greatly affect areas that are highly dependent on agriculture and natural resources. In this regard, research has been conducted on rainfall patterns in Maros Regency. The study used rainfall data analyzed using the isohyet method. The results of the study showed that rainfall patterns in the Maros Regency area in the last 10 years showed increasing shifts and variability, especially in the last three years (2021-2023). This can be seen on the 2014-2020 isohyet map showing that the distribution of rainfall in Maros Regency is uneven, with a tendency for increasing rainfall from the southwest to the northeast, in 2021 there was a change in rainfall intensity in the northeast and several central areas, in 2022 there was a decrease in the highest rainfall in the northeast and an expansion of the low rainfall area to the center, in 2023 an increase in rainfall in the southwest, the dominance of the 2000-3000 mm interval in most areas, and the disappearance of the very high rainfall zone in the northeast are important changes that indicate significant climate dynamics
