We developed a more accurate method of analysis for low-concentration volatile compounds used for the determination of free dimethylsulfide (DMS) in marine phytoplankton by using solid phase (SPME) gas chromatography - spectrometry Mass of GC-MS and head space method. DMSP, as a product of bacteria degradation has been scientifically recognized to be affected by climate change due to increased in sea surface temperature, and form DMS compunds.. The present study is to determine the DMSP concentration and degradation pathway in the oligotrophic region of Spermonde waters. The spatial and temporal correlation between DMSP degrading bacterial codes and biological potential controls for DMS formation in the open seas was examined using a statistical factorial analysis of variance and regression against the spatial (or distance) gradients of the Spermonde coastal waters, the concentration of chlorophyll-a, and diatom community structures. Seawater chemical properties, chlorophyll-a, and diatom samples were collected from several sites in the Tallo-Makassar river estuary, and the Pangkep river in September 2017 (transitional wet-to-dry-season). The result shows that the concentration of the Domination Index was higher in the transition season of 35.2 to 85.2 μM than in other seasons. The abundance of diatoms during the transition season reached 16,534 plankter / mL.

Research on the phenomenon of climate change on the region Makassar Strait waters that are part of the oceanographic activities that require observation of the sea surface temperature (SST), surface currents and ocean color imagery from satellite imagery. In this case, satellite remote sensing data using Aqua-Modis analyze both visually and raw-surface temperature parameter data in order to study a variety of other related phenomena that take place in the ocean. The existence of satellite imagery data for the observation of parameters and / or oceanographic phenomena will be more profitable in terms of time and cost and high accuracy. The purpose of this study was to review based on the description of the SST analysis using Aqua-Modis image data (non-commercial) and open source software in providing the information cepatdan applicable. Bodies Spermonde been considering the seas is quite unique because it is located right in the path of the current meeting of the Pacific Ocean through the sea of Sulawesi and spacious enough for the continuity of mesoscale oceanographic processes for coverage in the waters Spermonde in (islands) Indonesia

Plankton abundance is influenced by seasons, sea surface currents (SSC), nutrients and surface temperature (SST). Is a marine organism has a function to stabilize the surface temperature of the earth by regulating the concentration of Dimetyl sulfide (DMS) due to exposure to direct sunlight. There is the ability of the ocean to regulate warming and to regulate the distribution of water vapor in the atmosphere which is controlled by sea surface temperature. Sampling using the transeck system in September and January represents the rainy season and the dry season which is closest to the Tallo river estuary and the Pangkep river estuary represents the estuary region, towards the coast of the spermonde (Litoral) islands and far from the coast (offshore) from freshwater sources, but the relationship of nutrient entry into estuary areas by sea surface currents (SSC) is still poorly known. The dominant aspect of phytoplankton is determined by the amount of nutrients flowing (runoff) from land to estuary to spermonde waters

Land cover change is a major problem with environmental sustainability. The impact of the increasing population is urgent for the need for land for human activities. The purpose of this study is to determine the magnitude of land cover changes that occur in Sinjai Regency for the period 2014 to 2022. The research uses quantitative research. That is research that starts from a specific plan or a detailed set of questions or hypotheses. This research is closely related to the process of enumerative induction (induction based on calculations). Based on the analysis using imagery data, the rate of land change in Sinjai district was obtained as follows: : land cover in the form of mixed land decreased by 287.61 Ha, secondary forest decreased by 135.98 Ha, primary forest by 20.04 Ha, water body by 140.46 Ha and other uses increased by 586.53 Ha.

This study aims to (1) Determine the rate of change in the temporal function of the hedge. (2) Determine the value of the protection coefficient based on the results of satellite imagery analysis. The method used in this study is spatial descriptive, with land units as units of analysis or mapping units. In spatial description, the results of the study will be described and displayed in the form of a map. In this study, it will be described spatially and temporally the land cover and its effect on the index of protected function of the research area (Sinjai Regency Watershed). The analysis used is spatial analysis whose processing uses a Geographic Information System, with outputs including Land Use Maps and Land Cover Maps. In the period 2014 - 2022, there was a dynamic change in land cover in the Sinjai Regency watershed. The largest land cover that has changed is miscellaneous use which changed 49.87%, then mixed land which changed 24.66% and water body 12.20%. The index of the protected function of the Sinjai Regency Watershed in 2014 was 0.57 and in 2022 it was 0.50. During the period 2014-2022 there was an increase in the hedging function index by 0.02.

The Seruni Women's Farmers Group (KWT) whose address is at Bumi Tamalanrea Permai Housing Block G, Buntusu Village, Tamalanrea District, Makassar City was formed on March 12 2013, this KWT is chaired by Hj. Hartinawati, assisted by A. Emilda as Secretary and Hj. Zaenab as treasurer and 27 other members were formed from the Food Security program with the aim of realizing food self-sufficiency. This KWT utilizes empty land which is a public facility (Field) in the BTP Bloh H housing complex. Seruni KWT focuses on horticultural plants, especially vegetables, considering that the planting area is not very large, only using a green house. ccording to the results of an interview with the chairman of KWT Hj. Hartinawati said that Seruni KWT is urban farming in nature because it is located in the middle of an urban settlement and consists of housewives who have other routines so it has not been managed optimally. The main problem is related to production, namely the cultivation aspect in terms of maintenance, the lack of personnel in charge of carrying out maintenance, especially watering. The solution offered to overcome partner problems related to sustainable maintenance is the creation of IoT-based sprinkler irrigation for watering with the aim of making efficient use of water, time and labor. The approach method for solving the problem is the delivery of theoretical material regarding the use of IoT-based sprinkler irrigation, and marketing techniques. and continued with a demonstration and practice of designing an IoT-based sprinkler irrigation system carried out by KWT members. The expected target of this activity is: partners can increase their farming results and become a pilot project for urban fa rming activities. Keywords : Sprinkler, Farming, KWT, IoT

The contribution of the mining sector to forest destruction in Indonesia has reached 10% and is now increasing every year to reach 2 million ha. Efforts to improve ex-mining land is by reclamation. The purpose of this study is to determine the design of reclamation activities and to evaluate the success of reclamation at PT. Citra Lampia Mandiri. The research method used is descriptive method with data collection techniques that are participant observation. Reclamation activities are carried out in several stages and activities that are systematic and well planned which have links between one activity and another in an effort to improve land quality. To determine the success rate of reclamation by providing an assessment of each reclamation activity, namely land use and revegetation, erosion and sedimentation control, top soil management, revegetation activities and plant maintenance. The results of the evaluation of the success rate of reclamation at PT. Citra Lampia Mandiri is 83% with good description.
