Abstract

, because there are still many residents who do not understand what floods are and what to do when experiencing floods. To provide awareness about floods, education about floods must be carried out for children and the elderly so that it occurs. similarities in perception and knowledge about this matter, especially for city residents in upstream areas such as in Mandalika Village. Education about floods is carried out in several stages, including the initial survey stage, coordination, discussion, question and answer activities and evaluation. The counseling material provided includes perceptions about floods, factors that cause floods, ways to avoid and reduce the occurrence of floods and the infrastructure needed to anticipate floods. During the outreach process, discussion and question and answer sessions were also provided, to increase participants' understanding of floods. The result of the service that has been carried out is being able to provide counseling to the community, both young people and parents, totaling 25 representatives who attended, including the management of Banjar Sedana Ayu. Participants have gained knowledge about floods and have understood the phenomenon of flooding and ways to avoid it after a question and answer session at the end of the outreach activity. By having the participants at the location of this trial, some of the people in the Mandalika sub-district already understand how floods occur and are expected to be able to deal with them if they happen.

Abstract

The use of multistage drip irrigation needs to be supported by adequate planting media so that irrigation water can be provided optimally. The planting medium used is practically soil mixed with compost and put in a polybag. Therefore, by adding compost with a certain composition to the soil, it is hoped that a good planting medium will be obtained. This test aims to determine the effect of using cocopeat compost and cow compost as well as soil as a planting medium in polybags on providing multistage drip irrigation. Flow characteristics on the distribution of irrigation water, its absorption capacity, absorption rate and irrigation uniformity achieved. The test was carried out on a ½” PVC drip irrigation network with a 2 lt/hour emitter consisting of 4 network levels on land measuring 2m x 4m, water source from a tower with a height of around 2.5m and a tank capacity of 150 liters. Test data for analysis consists of irrigation volume and distribution, drip system flow rate, irrigation uniformity (Cu), infiltration rate and irrigation depth. The analysis results show that the average irrigation distribution on floors 1 to 4 is 3028ml, 2937ml, 2848.25ml and 2793 ml, with flow rates on floors 1 to 4 of 40ml/s, 39 ml/s, 38 ml/s and 37 ml/sec. The amount of drip discharge (qt) on the 1st floor was 6.7ml/sec, on the 2nd floor the amount was 6.5 ml/sec, on the third floor it was 6.3 ml/sec and 6.2ml/sec on the 4th floor. Irrigation uniformity was obtained by 96% is considered very good, with an average infiltration rate hc in V2 of 0.04 cm/s, in V3 the hc was 0.03cm/s and in V4 the hc was 0.027cm/s. So the irrigation infiltration rate when using cocopeat tends to decrease if the portion of the planting medium increases, so its use needs to be limited.

Abstract

Soil moisture is the most important part of irrigation activities, because it is the result achieved by providing irrigation on a particular land. Likewise, with the application of drip irrigation, soil moisture is also the purpose of irrigation in the planting medium. In multilevel drip irrigation sistems, the potential for soil moisture produced by the irrigation sistem is very important to pay attention to, because the size of the moisture that can be provided will affect the scheduling of the drip irrigation provided. And therefore the ability of an irrigation sistem to provide optimum soil moisture in a particular medium deserves attention, before the sistem is applied to farming activities. For this reason, this test aims to determine the ability to provide soil moisture in a drip irrigation sistem that uses a 4 liter/hour emitter in a 4-tiered drip irrigation network, a polybag planting medium and an irrigation duration of 5 minutes to 20 minutes. The test data analyzed is irrigation and soil moisture distribution data, then the results of the analysis are presented in tabular form and discussed and conclusions are drawn. The test results show that the distribution of drip irrigation water occurs evenly with the optimal application of 41% moisture, and with the application of additional soil moisture of around 6% -7% for an irrigation duration of 20 minutes. The daily decrease in soil moisture that occurred during the three days of testing was found to be around 2% as a result of evaporation

Abstract

The utilization of multilevel drip irrigation needs to be supported by adequate planting media so that the provision of irrigation water is optimal. The planting media used practically uses soil mixed with livestock waste compost and cocopeat in polybags. This test aims to determine the ability of drip irrigation water absorption by the planting media in the form of irrigation depth and soil moisture provision and prediction of irrigation application with a certain duration. The study was conducted on a ½” PVC pipe drip irrigation network with a 2 lt/hour emitter, on a land size of 2 m x 4m x 2m with a water source from PDAM water which is stored in a tank with a capacity of 150 liters and a height of 2.5 m. The test data taken includes data on the distribution of irrigation volume, irrigation depth and soil moisture. The results of the analysis showed that the distribution of drip irrigation depth in cocopeat media ranged from 7.5 cm - 12 cm in 5 minutes, while in rice husks the absorption was around 6.5 cm - 10 cm for the planting media level, with an average Cu of 96% which is very good. The maximum soil moisture that can be provided by four-tiered drip irrigation at a duration of 5 minutes is 30.5% in the early growth phase and at a duration of 10 minutes the average soil moisture is 15%, in the Vegetative phase of plant growth until fruit ripening. So the high irrigation infiltration rate in cocopeat media has the potential to be applied to plants that have long or deep roots, while planting media with rice husks has the potential to be applied to plants with short roots such as vegetables.

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

Abstract

Climate change has had a real impact on the agricultural sector, especially in rural areas where the majority of the population depends on agriculture. This community service activity was carried out in Batu Rimpang Village as an academic contribution to enhance community resilience in facing the impacts of climate change through education and the application of water-saving irrigation technology. This program focused on socializing the climate change impacts, followed by hands-on training in installing sprinkler irrigation systems as a simple but effective solution so that farmers can continue to cultivate their land in the limited water availability. The socialization session was carried out interactively and continued with installing sprinkler practice so that participants could understand the technical aspects and benefits of the irrigation system that had been implemented. The training went orderly, attended by around 20 farmers who showed high enthusiasm in each session. This activity has not only increased community’s understanding of climate change adaptation, but also encouraged local initiatives to adopt more efficient and environmentally friendly technologies. It is hoped that this initiative will contribute to the achievement of Sustainable Development Goals (SDGs)-13 on climate action by increasing the adaptive capacity of communities, thereby reducing the potential impacts of climate change in Batu Rimpang village.
