Abstract

The dam is a crucial river-crossing structure that ensures a sustainable water supply and offers numerous benefits. However, the potential hazard of dam failure is an imminent threat that could materialize unexpectedly. To comprehend the potential impact of dam break flood and identify vulnerable areas, it is essential to conduct rigorous analysis and simulate various dam failure scenarios. This comprehensive assessment is invaluable for informed land use planning and the development of effective emergency response plans. Therefore, this study aimed to analyze flood inundation resulting from the hypothetical failure of Gongseng dam, using Iber model. The modeling approach relied on a two-dimensional finite volume shallow water model, guided by specialized software. The scenarios for Gongseng dam break showed inundation areas of 12.57 km² and 7.55 km² for overtopping and piping failure, respectively. Overtopping failure resulted in the highest discharge, with Von Thun method causing severe damage due to wide break dimensions, and eventually leading to catastrophic consequences. However, this study showed that Froehlich method provided the most rational prediction for break parameters. In contrast to the other methods focusing solely on water height behind dam, Froehlich equation considered both the volume and height at the time of failure. Implementing dam break analysis held the potential to benefit downstream communities by providing inundation maps, thereby aiding in the mitigation of flood risks. Particularly, in situations with limited data and resources, as shown in this study, the cost-effective modeling method proposed could be an attractive option for simulating extreme flood induced by dam break.

Abstract

The form of cooperation agreement made by managers and investors of shrimp ponds in the Gampong Lhang Village is to provide loans to managers who are considered feasible and trustworthy to manage the ponds with an agreement that the capital will be fully provided by the pond owners. The profit sharing process is explained at the time of the agreement between the pond owner and the manager, the profit sharing is 70% for the manager while 30% for the owner, but there are also some who share 40% for the owner while 60% for the manager, in this case more profit is given to the manager because of course the responsibility is heavier felt by the manager. The mudharabah contract carried out by the community is in accordance with sharia, because the basic concept of the contract is that there is an agreement between the two parties and no party is forced to enter into the cooperation agreement, therefore this contract can be said to be valid, unless there is one party who feel compelled or threatened to do the contract, then this is not allowed in Islam of course.

Abstract

Coastal zones are inherently dynamic, often resulting in long-term cumulative impacts such as erosion, which can potentially escalate into disasters. Discussions regarding nature-based solutions, particularly the utilization of coastal forests, have gained prominence due to their environ[1]mental benefits. This paper investigates the role of vegetated coasts in mitigating the effects of wave attacks on land, focusing specifically on Coastal Pandanus species. We conducted a systematic monitoring effort to quantify land changes directly around these species in the field. The southern coast of Java, characterized by significant coastal processes, served as the investigation site. We monitored the changes in the foredunes of eight Pandanus clusters identified along a 1 km stretch of the Pandansari and Samas coasts in the Special Region of Yogyakarta, Indonesia. Our systematic monitoring, conducted biweekly from September to December 2023, involved precise measurements of land elevation, sediment deposition, and erosion around the Pandanus clusters. We utilized manual leveling surveys and installed erosion pins to enhance the precision of our topographic assessments. These monitoring techniques allowed us to thoroughly examine the relationship between Pandanus cluster characteristics and coastal processes. Our findings illuminate the pivotal role of Pandanus clusters in shaping coastal profiles, which depend on cluster area and growth characteristics. Additionally, we underscore key points regarding their success rates, limitations, and future strengthening efforts through the implementation of this nature-based solution. This research contributes to a deeper understanding of the complex interactions between coastal dynamics and vegetative elements, paving the way for informed coastal management strategies in the future.

Abstract

This research was conducted to determine the wage system in the perspective of Islamic law, with data collection techniques using observation and documentation methods. Data analysis in this study will use qualitative data analysis which is constructive, develops and discovers social theories. The results obtained from this study are that the wage payment system must be in accordance with the agreement, so that wage earners can overcome some of the economic difficulties that are needed daily. The act of delaying the payment of wages without a valid reason is very contrary to Islamic law and is classified as an unjust act, what is more important in the matter of wages is that before working as a girlfriend, both parties first inform or provide an explanation regarding the amount of wages that must be received or arrested. so that there is no interpretation at a later date. Islam also explains that in the wage payment system, the wages that workers will receive
