Analisis Potensi Debit Air Tanah Melalui Pumping Test Metode Step Draw Down pada Sumur Bor Irigasi di Desa Bonto Rannu, Kecamatan Kajang, Kabupaten Bulukumba, Sulawesi Selatan

The rice fields in Bonto Rannu Village, Kajang District, Bulukumba Regency are dominated by rainfed rice fields. This species has limitations in the dry season because irrigation/agricultural irrigation is completely dependent on rainwater. Therefore, it is necessary to identify alternative irrigation sources for the sustainability of farmers' farming activities in Bonto Rannu Village. This study aims to analyze the quantity of groundwater wells by testing in the form of a pump test (pumping test) with the step draw down method. The optimum discharge (Qopt) of well 1 is 0.01876 m3/s or 67.53 m3/hour with an optimum Sw of 2.891 m. This shows that groundwater in well 1 can be pumped at 67.53 m3/hour with a decrease in water level of 2.891 m with the pump condition still technically safe. As for well 2, the optimum discharge (Qopt) is 0.00318 m3/s or 11.45 m3/hour with an optimum Sw of 2.100 m. These data indicate that there are limited groundwater reserves.The rice fields in Bonto Rannu Village, Kajang District, Bulukumba Regency are dominated by rainfed rice fields.

Distribution of mangrove health in the coastal area of Maros Regency in 2021 based on Sentinel 2 satellite imagery

Changes in the area of mangroves in the coastal area of Maros Regency have been degraded from year to year. Various problems that often occur cause a decrease in the distribution and quality of mangrove community health. This happens because there is still pollution and external disturbances which make the quality of the mangroves decrease. Therefore, it is important to know the condition of mangrove distribution to find the latest information and baseline data for area managers. The purpose of this study was to obtain information on the extent and type of mangrove health, as well as identify the types of mangrove damage in the coastal area of Maros Regency in 2021. This research method used (1) supervised classification, to obtain mangrove distribution, (2) analysis of mangrove health using the normalized difference algorithm vegetation Index, (3) map overlay, mangrove distribution map, administrative map, and mangrove health index map, (4) validation of mangrove health data through an assessment of mangrove conditions based on the distribution of observational plots in a proportionate stratified with random sampling. Mangrove areas are found in the coastal areas of Maros Regency and are scattered in Marusu District, Maros Baru District, Lau District, Bontoa District with an area of 131.87 ha, 95.59 ha, 85.37 ha, and 60.01 ha, respectively. Mangrove health is divided into 5 categories, namely excellent, good, normal, bad, and awful with an area of 100.73 ha, 240.43 ha, 1.99 ha, 9.5 ha, and 20.2 ha, respectively. While mangrove damage based on 30 sample points, 6 types of damage were identified, namely changed leaves, damaged shoot leaves and shoots, broken/dead branches, open wounds, resinosis, and broken stems with percentages of 29.91%, 19.63%, 17.76%, 16.82%, 12.15%, and 3.74% respectively

PEMANFAATAN CITRA ALOS PALSAR UNTUK ESTIMASI KANDUNGAN SERAPAN KARBON DI WILAYAH PESISIR KABUPATEN MAROS

This study aims to determine the type of land use in 2009 using alos palsar image, then calculate carbon stocks and sequestration using the 2006 IPCC Software approach. The data sources of this research are primary data and secondary data. Primary data in the form of data obtained through the interpretation of Alos Palsar Imagery, while secondary data is data obtained from literature studies concerning the results of measurement data in the form of volume, diameter and tree height at the research location. The data will be calculated using IPCC GL 2006 software. The results showed that the land cover of the coastal area of Maros Regency based on Citra Alos was dominated by ponds and grasslands with an area of 59.05 ha of the total coastal area, while the forested area was only a small part, namely 1.16% mangrove forest and 0.94% agroforestry. Mangrove forest and agroforestry are the largest carbon storage areas in the coastal area with 96,223.52 and 33,608.81 tons, respectively. Based on IPCC mangrove forest and agroforestry have carbon sequestration of 22.39 and 9.6 tons/(ha/year, respectively). However, with carbon sequestration of only around 2.4 and 5.1 ton/(ha/year) rice fields and shrubs actually show that the total carbon absorption in coastal areas has 8,901.36 and 7,159.25 ton/year. With a very small area, mangrove forests and agroforestry are able to absorb carbon of 4,811.18 and 1680.44 tons/year

PENGARUH PENGETAHUAN EKOSISTEM, PENGETAHUAN KONSERVASI, DAN PENGETAHUAN PENCEMARAN, TERHADAP SIKAP MEMELIHARA LINGKUNGAN MASYARAKAT DIWILAYAH DAS MAROS BAGIAN HULU KABUPATEN MAROS

The Maros watershed area in Tompobulu District is experiencing environmental degradation, especially forest destruction, a high rate of erosion, and deforestation that is mostly done by the surrounding communities. Other damage is also caused by the conversion of forests into estate crops. Forestry Service Data Kab. Maros in 2017, stated that the level of forest degradation and damage in the upper Maros watershed area is estimated at around 7,936.76 ha, where the average annual rate of forest degradation and critical land is around 372.94 ha / year, or estimated to be around 20-25 years forests will come in the upper watershed of the Maros watershed due to forest destruction. Damage to the upper watershed of the Maros watershed which has resulted in a decrease in water discharge has given misery to the surrounding communities, especially in the need for water in agricultural areas and also the need for water as a source of drinking water. This phenomenon is happening right now, which must be considered by all parties concerned with the Maros River Basin. Conversion of forest land in the upper watershed region due to pressure on economic needs and the need for clothing and boards such as taking wood to make houses, making impromptu rice fields, and wood as fuel. This activity has become a community activity that results in higher degradation of forests and critical land, which has implications for decreasing water debit in the upper Maros watershed. From these problems, it can also be said that the tendency of Maros Bagan Hulu watershed damage is possible because there are community attitudes in maintaining the watershed environment that tends to be less responsive to the watershed damage problem, which in turn will behave negatively towards the use of watershed without paying attention to aspects of the sustainability of watershed management. . The tendency of negative community attitudes towards environmental management in the watershed region can also be caused by the lack of understanding and knowledge of the community about ecosystem knowledge, conservation knowledge and pollution knowledge that exists in the upper Maros watershed. The purpose of this study is to analyze ecosystem knowledge, conservation knowledge, and pollution knowledge that influence the attitude of caring for the environment, the community in utilizing the upper Maros watershed. This study uses a quantitative approach and hypothesis testing and survey methods with questionnaire type instruments. The instruments used were developed by researchers, including: ecosystem knowledge questionnaires, conservation knowledge, pollution mitigation, and environmental care attitude questionnaires. Based on SEM analysis method, it can be said that conservation knowledge (X2), and pollution knowledge (X3) have a direct and significant effect on the attitude of caring for the environment (Y). While the ecosystem knowledge variable (X1) does not have a direct and no significant effect on attitudes to care for the environment in the upper Maros watershed, this is indicated by the significance value of p - value> 0.05
