Abstract

Sumbawa Island is one of the largest islands in West Nusa Tenggara (NTB) Province with an area of 15,414.5 km². Climatic conditions greatly influence the economy of the people of Sumbawa Island because most of the population earns their living as farmers, planters and livestock breeders. Extreme climate changes often occur. This results in natural disasters such as floods, landslides and drought. Sumbawa Island itself often experiences floods in the rainy season and droughts in the dry season. Knowledge of climate characteristics will really help the people there, in overcoming and avoiding the impacts of extreme climate change now and in the future. This research functions to provide information regarding the climate characteristics of Sumbawa Island.The method used to analyze the climate characteristics of Sumbawa Island is the Thornthwaite and Schmidth-Fergusson climate classification methods. The data used is secondary data for 14 years (2005-2018). This data was obtained from the NT I River Basin Center and generation data using the Thomas-Fiering model for the next 10 years (2019-2028).The results of the analysis showed that according to Thornthwaite, Sumbawa Island in the 2005-2018 and 2019-2028 periods had the same climate type, namely a dry climate (E) based on an average PE index value < 16 and a tropical climate (A) based on an average TE index value. ≥ 128. According to Schmidth-Fergusson in the 2005-2018 and 2019-2028 periods, Sumbawa Island has the same 3 types of climate, namely a moderate climate (D) with a value of 0.6 ≤ Q < 1, a slightly dry climate (E) with a value of 1 ≤ Q < 1.67 and dry climate (F) with a value of 1.67 ≤ Q < 3.

Abstract

The aim of this study is to determine the discharge of rainwater runoff from different durations of rain, to determine the magnitude of the differences in the discharge of rainwater runoff produced, and to determine the differences in channel dimensions resulting from differences in the duration of rain used. This study uses 6 years of daily rainfall data recorded at Bengel Station, to calculate the planned flood discharge as an alternative for controlling rain runoff in the Green Asia Housing area with a land area of ±6 hectares, a test time was used with rain times selected as 24 hours and 5 hours. Flood discharge is calculated using the Rational formula with a rain return period of 2 years according to the design area. The results of data analysis will be presented in the form of tables, discussed and concluded descriptively.The results of the study show that there is indeed a quite large difference in flood discharge, where the use of a 24-hour rain period produces a planned discharge that is around 32% lower than the use of a 5-hour rain period. The dimensions of the channel produced for a discharge with a rain duration of 24 hours are also smaller than the dimensions produced by a flow discharge with a rain duration of 5 hours. The fact is that rain events with a duration of shorter than 24 hours are more common than rain events lasting a full day.

Abstract

Drought index analysis requires long data requirements. However, the complete and long recording periods of rainfall data are still the main obstacles to meeting rainfall data needs. Apart from that, there are still many areas that do not have adequate and evenly distributed rain recording stations. This research aims to see if the use of CHIRPS (Climate Hazard Group Independent Precipitation with Station Data) satellite rainfall data can be used to calculate the drought index using the SPI (Standardized Precipitation Index) method. The research began with collecting rain data from ARR measurements and downloading CHIRPS satellite rain data. CHIRPS data is corrected first by reducing the correction factor using simple regression where CHIPS data is the independent variable and ARR data is the dependent variable. CHIRPS data was then corrected and used in calculating the drought index using the SPI method. The results of the SPI calculation from the corrected CHIRPS rainfall data were then compared with the drought index resulting from analysis using ARR data. The results obtained show that both CHIRPS data and ARR data produce the highest drought index with the Normal severity category. The drought index resulting from CHIRPS data analysis is stated to be quite good and corresponds to a suitability level of 60%. So the CHIRPS data is declared good and can be used for drought analysis in this region.

Abstract

Changes in land use that have occurred over a period of several years in the Kuta area have resulted in a lack of water catchment areas. The impacts caused by the lack of catchment areas are flooding and reduced water quality in rivers. The flood disaster in the Bengkang River caused damage to bridge infrastructure and people’s homes. The Bengkang river basin is divided into 3 sub – basins with a total area of 10,45 km2. Based on the results of the design flood analysis using the Nakayasu synthetic unit hydrograph method, the largest flood discharge value was obtained, namely 32,859 m3/second for a return period of 25 years. Hydraulic modeling was carried out to determine the water level and the ability of the river section to receive flow using HEC-RAS 6.1 software. Based on the simulation results with a return period of 5 years, it is known that flooding occurs in the middle and lower reaches of the Bengkang River, so structural mitigation is needed, namely normalization and repair of embankments. A 25-year return period flow simulation was carried out using a cross – section of the channel plan and no runoff was obtained in the Bengkang River.

Abstract

East Suwangi Village is one of the villages in Sakra District, has an area of ​​2.17 km2, has hilly geographical conditions and a population of 5,069 people. Based on survey results and interviews with village heads, some areas are prone to flood disasters. The flooding that occurred was caused by overflow from drainage channels, causing it to accumulate on roads and residential areas. One effort to minimize inudation is the implementation of an environmentally friendly drainage system by constructing infiltration wells along flooded channels. The method used in this community service activity is to explain environmentally friendly drainage systems to the community and the practice of making infiltration wells in locations that are often flooded. The result of this activity is an increase in public understanding of the function and benefits of infiltration wells as a medium for environmentally friendly flood management. And the public can see firsthand how to make infiltration wells through practice in locations that are often flooded.

Abstract

The problem of clean water for people in the highlands always arises every dry season. Getting clean water every day requires a lot of effort to find a water source that is very far away. Some people even have to spend additional money to get clean water. This is also the case with people in Batulayar sub-district who live in the highlands, especially in the mountains. Surface water sources are not available so that it becomes a routine problem every year. In overcoming this problem, some people make rainwater reservoirs either in groups or individually. The reservoir is made with several materials in the form of a reservoir by making a hole in the ground surface covered with plastic or tarpaulin and a reservoir made of brick/brick masonry. The method of capturing water is directly from the ground surface by making a channel and there is by making a reservoir from local materials in the form of bamboo which then the captured water is channeled into the reservoir. The use of local materials in the form of bamboo is very potential to be used because in the Batulayar area, especially in the mountains, the availability of bamboo is very abundant. Bamboo with an age of 3 years already has quite high strength both for water flow materials and as construction materials. The weakness that is still faced by the community in utilizing bamboo is the connection method which is still very simple, so that when it rains with high intensity the connection comes loose. In using bamboo as a rainwater catchment network, it is very important to socialize the right connection model to be used in capturing rainwater.

Abstract

Prako Weir in East Lombok Regency has limited water availability, which affects its ability to serve the provision of irrigation water. Failure to meet irrigation water needs is increasingly felt, so adaptation steps are needed to reduce more significant losses at the farmer level. This study aims to evaluate the current cropping pattern and obtain alternative cropping patterns that are more appropriate according to water availability in Prako Weir to minimize the potential for farmer crop failure. The study began by analysing water availability by calculating the mainstay discharge using a ranking method using Prako Weir discharge data. Continued analysing water requirements in the current cropping pattern and several alternative cropping patterns using the KP-01 method. Furthermore, the best cropping pattern was selected using the water balance method. The results obtained were the best cropping pattern according to the water availability pattern in Prako Weir, namely Rice-Soybeans-Soybeans, which began planting in early October, with an annual water surplus of 775.24 l/second. Meanwhile, the current cropping pattern, Rice-Rice-Soybeans, shows an annual deficit of 625.31 lt/second. However, if economic considerations are used, then the current planting pattern is still acceptable even though it is at risk of being unable to meet its water needs. However, a solution can be taken by providing water in turns.

Abstract

The legal age of marriage in Indonesia is a man and woman who have reached the age of 19 as stated in Law Number 16 of 2019 on the amendment of Law Number 1 of 1974 concerning marriage in Indonesia. Marriage under the age of 19 is called early marriage, which is known as the "Merariq Kodeq" tradition for the Sasak tribe in West Nusa Tenggara. The purpose of this research is to find out the ethnobiological perspective of the Merarik Kodeq culture in West Lombok and find out the efforts that have been made by the local government of West Lombok Regency to prevent the increasing prevalence of Merarik Kodeq West Lombok. This research uses descriptive qualitative methods. The informants involved in this study were selected using a purposive sampling technique based on predetermined criteria, namely couples who married at an early age. The results stated that the average age of early marriage in West Sekotong Village is 16-17 years old. At this age, the reproductive organs are still in the developmental stage, especially the female reproductive organs which will function as a place for the development of the fetus. So if a pregnancy occurs at this age, there will be a high risk of miscarriage, birth defects, and even death of the mother and baby. So that to address the increasing number of Merarik Kodeq or early marriages the local government formed a movement known as the Anti Merarik Kodeq Movement (GAMAK).

Abstract

Jerowaru Beach, located on the southern coast of Lombok Island, is facing a significant threat due to coastal abrasion, which damages both road infrastructure and the environment. Abrasion, the process of land erosion caused by ocean waves, leads to the erosion of coastlines, damage to coastal protective structures, and alterations in coastal ecosystems. At Jerowaru Beach, the effects of abrasion include road damage and the loss of vital natural habitats such as mangrove forests, which are essential for coastal protection and supporting local species. Raising community awareness about the role they can play in mitigating abrasion's impact is a crucial first step toward reducing damage and enhancing environmental conservation efforts. On July 29, 2024, a socialization event was held at Bale Mangrove Jerowaru Beach, involving PMD KKN students and local residents. This event included training on mitigation techniques such as mangrove planting and the construction of coastal protection structures, as well as awareness campaigns through local media and community events. The socialization efforts resulted in increased public understanding of the impact of abrasion and the importance of mitigation measures. Active community participation in rehabilitation activities and collaboration with relevant stakeholders, including the government and NGOs, has also enhanced the effectiveness of these efforts. This socialization serves as a foundation for developing further mitigation strategies that involve ongoing community involvement and continuous monitoring. In conclusion, community engagement in mitigating abrasion at Jerowaru Beach is crucial for protecting road infrastructure and maintaining environmental sustainability. Recommendations include developing abrasion-resistant infrastructure, securing funding, and conducting regular monitoring to ensure the success of mitigation strategies
