A river basin (DAS) is an area bordered by mountain ridges where rainwater that falls on the area will be collected by the mountain ridges and will be channeled through small rivers to the main river (Asdak, 1995). A watershed includes a land area which is one unit with a river and its tributaries, which functions to accommodate, store and channel water originating from rainfall to a lake or to the sea naturally, where the boundary on land is a topographical divide and the boundary at sea is up to with water areas that are still affected by land activities. The Lematang River is one of the longest rivers in South Sumatra, the length of the Lematang River is 271 km with a watershed area (DAS) of 295.88 km2. The existence of the Lematang watershed is a source of life for the Lahat community. The decline in the carrying capacity and carrying capacity of the Lematang watershed due to land use can be seen from flash floods and landslides, where flash floods bring sedimentation, logs of wood and twigs causing losses to the community. To overcome the problems of the Lematang Ulu watershed, Integrated Watershed Management is needed by taking concrete steps in the form of efforts to formulate goals, synchronize programs, implement and control watershed resource management across stakeholders in a participatory manner based on studies of biophysical, economic, social, political and institutional conditions in order to realize the goals. Watershed Management.

Flooding is one of the disasters that often occurs in Indonesia, there are several cities that are always subscribed to flooding, one of which is Bandung Regency. On this occasion the author analyzed the vulnerability map in Bandung Regency using ArcGIS software by processing annual rainfall data, land use parameters, slope data, land elevation, and soil texture with this data the author obtained a percentage value of the level of flood vulnerability in Bandung Regency. Areas that have low elevations tend to experience flooding every year. From the processed data, there are 8 sub-districts in Bandung Regency with a flood prone percentage of more than 50%, namely Ketapang, Margahayu, Dayeuh Kolot, Pameungpeuk, Bojong Soang, Margaasih, Rancaekek, and Baleendah sub-districts. Based on the analysis of the flood prone map, most of Bandung Regency has a flood prone level classified as 'Less Prone', with an area of 64,277.228 hectares.

The research area is prone to flooding, which could potentially result in losses for the people of the research area. Based on this, it is important to map flood-prone areas, as a form of flood disaster mitigation effort to reduce the level of flood risk. Hazard mapping is an important stage in the process of disaster risk identification and analysis. Mapping flood-prone areas can use various methods or approaches. Approaches that can be used for assessing or mapping flood hazards are the geomorphological approach and community participation. This type of research is quantitative descriptive, namely a type of investigation that explains or explains a problem. Descriptive studies aim to explain populations, situations or phenomena accurately or systematically. Mapping flood hazards in the Koto Tangah District, Padang City. From the results of the analysis of the level of flood vulnerability above, the relationship between this research is that rainfall is too high and low river beds cause water to overflow into lowlands, causing the level of flood vulnerability to increase as time goes by. So The results obtained from the analysis of Flood Hazard Area Mapping are the area of ​​Koto Tangah sub-district is 22.017,43ha, by getting the level of non-prone areas with an area of ​​10.203.16ha, the level of less-prone areas with an area of ​​4.714.168ha, the level of vulnerable areas with an area of ​​3.990.458ha, the level of very vulnerable area with an area of ​​1.893,630ha. Koto Tangah District, Padang City has five levels of danger zones for flooding, based on the results of the parameter data used.

From the creation of flood prone levels in Koto Tangah sub-district, Padang city, areas with a very high risk of flooding are 10.68% with an area of ​​1892,630 ha, areas with a danger level of flood prone are 14.68% with an area of ​​3990,458 ha, areas with Kuang's flood-prone level is 21.40% with an area of ​​4714,168 ha, the area with a flood-safe level is 46.32% with an area of ​​10,203.16 ha.

Climate change has become a major factor in increasing forest fires in various parts of the world. This phenomenon has had serious impacts on the environment, economy and human health. Environmental conservation efforts are becoming increasingly important to reduce the risk of forest fires and maintain ecosystem balance. With a better understanding of the relationship between climate change and forest fires, preventive and adaptation measures can be designed to protect forests and ecosystems that are vulnerable to this threat. The purpose of this article is to discuss the impact of climate change on the increase in forest fires and environmental conservation efforts that can be taken to overcome this problem. The method used in this research is using a literature study method to collect information about the impact of climate change on forest fires and environmental conservation efforts. Climate change is significantly increasing the risk of forest fires worldwide leading to rising global temperatures that are drying out forests and increasing the likelihood of fires occurring. Changing rainfall patterns also lengthen and strengthen the dry season, increasing the potential for forest fires. These factors, along with human activity and extreme weather, have led to an increase in the frequency and intensity of forest fires. The impacts are far-reaching, including destruction of wildlife habitat, carbon loss, ecosystem degradation, and negative impacts on air quality and human health.

Floods are disasters that often occur in Indonesia. Disasters caused by hydrometeorological factors always increase every year. Even though sometimes it doesn't cause many casualties, this disaster still damages infrastructure and significantly disrupts the economic stability of the community. The characteristics of floods are very diverse, floods can be caused by high rainfall without adequate soil absorption or can occur in the form of flash irrigation failures. South Kalimantan is a city known as the "City of a Thousand Rivers", which of course cannot be separated from flooding situations every rainy season. One of them is quite common in urban areas, especially the city of Banjarbaru. The dense population and the presence of rivers sometimes cause flooding, especially if the intensity of rainfall lasts long enough. Likewise, what often happens in the Kemuning Banjarbaru sub-district, floods that often come suddenly have become a normal activity for local residents. Without hesitation, there were even (9) RTs that were affected by the flash flood. Even though they are used to facing floods, especially when the rainy season arrives, residents are still advised to always be alert.

This study seeks to create a system for monitoring the environment using the Internet of Things. It aims to help farmers manage their rice fields in a way that is both effective and sustainable. The system will provide farmers with real-time data on soil moisture, air temperature, and rainfall, allowing them to make informed decisions. Sensors will collect this information, which will be analyzed and presented simply through a web or mobile app. Early simulations suggest that this system could boost crop yields by as much as 15% and cut water use and costs by 20%.

Indonesia is a country that has extraordinary natural wealth because Indonesia is located in a tropical area which has high rainfall and sunlight almost all the time which makes plants grow fertile then has many mountains which are rich in minerals and has vast waters which are rich in minerals. marine animals and also Indonesia has abundant fertile land. Agriculture is the sector that receives the main attention in the development of food crop commodities. Indonesia is an agricultural country, where the main source of livelihood for the people is agriculture. This is motivated by geographical location. Indonesia is located in a tropical area, so the weather conditions, land and other resources in Indonesia have high potential to develop the agricultural sector. Based on these results, it can be concluded that all variables in this study are reliable. All variables have a normal distribution. This is proven by testing using the normality test. It is known that the Commodity Price, Land Area and Number of Areca Palm variables (X) and the farmer's income variable (Y) have values ​​greater than 0.05, so these variables have a significant effect. Based on the t test, the variables commodity prices, land area and number of areca nut have a significant effect on farmer income. The higher the price of commodities, the area of ​​land and the number of areca nuts owned and managed, the higher the price of commodities and the number of areca nuts and the area of ​​eating land that farmers' income will increase. Meanwhile, the analysis of commodity prices, land area and number of areca palms on farmer income based on test results (R2) has quite a large influence, namely 64.9%. Meanwhile, the remaining 35.1% was influenced by other factors not examined in this research. Thus, commodity prices, land area and number of areca nuts affect farmer income

Bukit Rata Village is a part of Kute Panang District, Central Aceh District, where high rainfall often occurs, so it is necessary to anticipate handling drainage problems.

The implementation of efforts to increase efficiency, care and maintenance of drainage consists of several stages, namely (1) observation stage, (2) program planning, (3) outreach, and (4) directing the implementation of the drainage maintenance program. As a result of this activity, the community is enthusiastic about participating in mutual cooperation activities to clean the drainage so that the drainage is clean and returns optimally according to its function.

Flooding is a problem that still requires special attention from a number of parties, including the community and the government. Flooding is not a light matter. Flooding can occur due to rising water levels due to above-average rainfall, temperature changes, levees or dams bursting, or obstruction of water flow elsewhere. The lack of community management and preparedness for disasters is one of the causes of the high impact of post-disaster damage or loss, so disaster mitigation is needed as an effort to reduce disaster risk. The research aims to analyze public knowledge about flood mitigation and preparedness. This study used qualitative research methods with the sampling technique used was simple random sampling. It was found that among several questions in the interview that the author asked about flood management knowledge and preparedness in flood disaster mitigation, all informants responded and acted very well. From the research conducted, all informants expect attention from the government to make improvements to the drainage system again and make new drainage. And the author hopes that the arrangement of residential areas on the banks of the river will be carried out to overcome floods that often hit the Kampung Baru area, Medan Maimun District.  

This research was conducted by involving the active participation of the Rungkut Kidul community. Through activities to introduce simple hydroponic concepts, communities are empowered to develop sustainable farming skills. The community is given knowledge about the basic principles of hydroponics, nutrient management, selecting suitable plants, and proper irrigation  techniques. The  results  showed  that  community  empowerment  through  simple hydroponics had a positive impact on the Rungkut Kidul community. Communities are able to independently implement simple hydroponic methods, increase crop production with better yields, and reduce dependence on environmental factors such as rainfall and poor soil quality. In addition, empowerment through simple hydroponics also has a significant socio-economic impact. The Rungkut Kidul community can utilize hydroponic crops for their own consumption needs and as an additional source of income through selling their crops at the local market. This reduces their dependence on external food supplies and boosts the local economy. The introduction of modern agricultural technologies such as simple hydroponics can provide sustainable solutions to increase local food availability, reduce dependence on uncontrollable environmental factors, and improve people's economic well-being.

Indonesia is a country that has potential water resources due to high rainfall but is very vulnerable to water crises. This fact shows the great urgency of the need for clean water. One effective solution to deal with this is through the use of rainwater. Harvesting rainwater is an effective step because Indonesia itself has high rainfall so that during the rainy season the product from PT Wujudkan, namely Gama Rain Filter, will collect water and in the dry season it will be used for daily needs. The purpose of this study is to find out about the implementation of the gamma rain filter in increasing access to clean water in rural communities. The research method used is a qualitative approach to gain a deep understanding of the effect of the Gama Rain Filter installation in increasing access to clean water in rural communities. The findings of this study are that with this superior technology, Gama Rain Filter helps people save water resources for drinking purposes during the rainy season. Therefore, existing funds can be used to obtain food sources that contain lots of protein

Flood is an event of flow or stagnation of water in an area that occurs due to the overflow of water from existing canals exceeding the capacity of water disposal caused by high rainfall and the topographical conditions of the area in the form of lowlands to basins, causing physical, social and economic losses. This type of research is qualitative research because the results of this research were obtained from various data collection techniques such as interviews, document analysis, observation and documentation. The population in this study were residents in Tanjung Rejo Village, Medan Sunggal District. The sample is part of the population that has a quality that can represent the entire population. The sampling process was carried out non-randomly (nonprobability sampling) with a purposive sampling technique, namely the method of taking samples based on certain withdrawals. The criteria referred to in this study are local residents who have been affected by floods.

Kukuh Village in Kerambitan District has a hilly topography, large rivers, and high rainfall, which makes the area prone to disasters, especially floods, landslides, and extreme weather. In order to overcome these problems, the Community Service Program (PKM) aims to: 1) create a Disaster Prone Map, Safe Zone Map, Evacuation Route Map, and Temporary Refuge Map; 2) build an informative, interactive, effective, and efficient village disaster information system based on digital technology; 3) organize counseling and training on disaster management to improve community preparedness; 4) provide disaster support tools. The implementation of the community partnership program uses the Knowledge Transfer approach through counseling and training, Technology Transfer through participatory mapping, and Diffusion of Science and Technology through the creation of the SIKADEK application (Kukuh Village Disaster Information System).

The Mediterranean region, in particular Algeria, is experiencing serious challenges due to the increased opportunities for forest fires. Since the mid-1970s, there has been a 50% reduction in rainfall over northwestern Algeria, making northern Algeria particularly vulnerable to the problem for many years. More than 37,000 hectares of sensitive forest are lost every year due to this extreme drought. The findings of this study, which assessed the hazard of forest fires from 2006 to 2019, agree with those of Bentchakal,Chibane (2022), who examined the problems caused by forest fires in the region. The aim of this investigation is to gain a better understanding of the problems caused by local forest fires and to use that expertise to provide insight for the authors and readers of this report. The report was written by presenting the findings of observations made using the Rapid Miner classification approach, which includes the categorization of areas affected by forest fires. Data is collected using a variety of algorithmic techniques, including Naive Bayes, KNN, and decision trees, which are used as tests of data to identify the most accurate results. The findings show that the Decision Tree technique has the best accuracy of 86.49% and provides a thorough explanation of the data.

Departing from the problem of disasters that often occur on river banks where when the rainfall is large enough, the river water discharge is also quite dangerous to the surrounding settlements. Therefore, we realized this greening program by planting tree seeds at a number of points around the riverbanks. With the goal of comprehensive river greening, an integrated, comprehensive, sustainable, and insightful plan is needed to think about the environment with the river as a management unit. This community service activity is carried out by the method of (1) community assistance in encouraging increased community participation (2) completion analysis problems and preparation of plans (3) Monitoring and evaluation of work program implementation activities.   The main target of this program is community groups and individuals who care highly about the environment with the aim of providing motivation for other communities. With the following stages of implementation: Consultation with the Village, Monitoring Planting Locations, Recruitment of seedlings at the Central Sulawesi Provincial Forestry Service, Planting on the banks of the hamlet 2 river, Planting on the banks of the hamlet 1 river, Planting in the yards of residents' houses, Planting at SD Negeri 2 Sindue   Tombusabora, Outreach on the dangers of throwing garbage into rivers and seas, Distributing plant seeds to residents. Greening is a means to overcome the environment so that the environment returns to health free from pollution.  

Accurate weather prediction information is important for various fields that are closely related to weather forecasting, such as agriculture, fisheries and many more. Because precise weather forecasts are very useful for various fields of carrying out various activities. Because of that, it is necessary to make an application to find weather or rainfall prediction information, so that the information can be utilized optimally by the community. In this journal the authors apply the k-nearest neighbors (k-NN) method based on rainfall data obtained from the Bogor climatology station from 2016-2017 and the test results show that the predicted rainfall for the Bogor area with the K-Nearest Neighbor algorithm obtained a value of 0, 93148.
