Abstract

This study examined water quality from various land cover in the Bialo watershed. Water sampling was carried out at three land cover namely, primary dryland forest, scrubland and dryland agriculture. sampling was carried out four times, two before rain and two after rain. The parameters measured were temperature, TSS, turbidity, color, pH, BOD, and DO. The results of water quality parameters are temperature values of 19.0-25.2 0C, turbidity ranged from 0.3-14,4 NTU, TSS 3.47-23.0 mg/l, color 0 Pt.Co- 39 Pt.Co, pH ranges from 6.99-7.16, BOD 0.29-2.05 mg/l and DO values ranged from 6.27-8.10 mg/l. The results of the study show that water quality in the Bialo Watershed from primary forest land cover is better than shrubs and dry land farming as indicated by the value of temperature, TSS, turbidity, color and BOD were low and high DO values.

Abstract

Soil and Water Conservation is an effort to protect, restore, improve, and maintain the function of the land by the capabilities and allotment of land to support sustainable development and sustainable living. This study aims to identify and assess the proper use of soil and water conservation techniques applied by farmers based on the assessment guidelines for soil and water conservation techniques and their relationship with socioeconomic factors that influence the actions of Soil and Water Conservation. Methods of direct observation in the field both in the form of surveys and in the way of interviews with farmers who apply soil and water conservation techniques. Data collected from socioeconomic factors such as age, level of education, income, number of family dependents, and area of ​​arable land. The data is processed by contingency techniques then classified and tested in chi-square.The results of this study indicate that the application of soil and water conservation techniques in The Catchment area of Nanggala river in the form of vegetative methods is applied in the way of cover crops, yards, and mixed gardens, while mechanical methods in the form of bench terraces. The application of soil and water conservation techniques by farmers is 67.75% correct, 9.67% somewhat proper, and 22.58% incorrect. Soil and water conservation techniques do not have a real relationship with socioeconomic factors.

Abstract

The biogeophysical characteristics of watersheds have an important role as a determinant of the river discharge amount in the watershed. Various watershed problems such as flood and drought related to river discharge require data and information. The importance of this data and information will determine a better watershed management plan. The issue of flooding and drought are the important issues in Ralla subwatershed, Souht Sulawesi Province. This study aims to describe the biogeophysical characteristics and the discharge of Lompo Riaja Atas and Lompo Riaja Bawah Rivers in Ralla subwatershed, Lisu Watershed. This research was conducted in from November 2016 to August 2017. Primary data collection was done through river discharge and precipitation measurements during 34 days of observation. Secondary data obtained from government or related agencies such as geological data obtained from Geological map of the Ujung Pandang sheet 1982, the slope data from Aster DEM, land type from RePPProt 1987, land cover data from google earth image 2015. A quantitative descriptive method was used to analyze the data obtained. The results showed that the Lompo Riaja Atas and Lompo Riaja Bawah rivers have relatively similar discharge fluctuation, although they have a different amount of discharge. River discharge of both rivers is more influenced by rainfall compared to biogeophysical conditions such as geology, topography, soil type, watershed area, watershed shape, river length and order, gradient, flow pattern, flow density,and land cover.

Abstract

Payment for Environmental Services (PES) is an environmental service compensation activity conducted by Forest Programme IV (FP-IV), designed to be implemented in the Mamasa Sub-Watershed of the Saddang Watershed. The implementation of this PES plan will be collaborated with parties such as the Bakaru Watershed Forum, Hydroelectric power plant (PLTA), and Forest Farmer Groups (KTH) in selected villages over a 5-year contract. However, the challenge is that the target community lacks trust in PES activities and most refuse to join, making the formation of KTH Mappideceng problematic. The purpose of community service is to enhance the capacity of KTH Mappideceng based on the requirements and criteria established by the PES model scheme. The methods used include primary socialization (door-to-door) such as surveys, lectures, and discussions. The results of the community service activities in KTH Mappideceng, Betteng village, showed an increase in the number of members from 12 to 21, with 15 being new members and 6 being existing ones. After the socialization carried out by the team, enthusiasm and motivation to join increased; however, the intervention location and funding limitations were predetermined by the PES model mechanism (FP-IV).
