Abstract

Many coastal structures or structures in coastal areas were destroyed by a tsunami attack. Such destructions were due primarily to the fact that such structures were not designed to withstand a tsunami. Those which were designed to withstand tsunami force may also have been destroyed due to some damaging factors which were not included in the design. The damage of the coastal structures is one of the important factors that have caused casualties. Especially, when the destroyed structures were originally aimed to mitigate the area against tsunami, they may cause higher fatalities. Examples of such structures are sea walls in many parts of Japan which were destroyed by the 2011 tsunami. This paper discusses the important factors relevant to the damage of seawall as tsunami mitigation structure such as impact force due to tsunami front, hydrostatic force, and hydrodynamic force, debris force and scour due tsunami. The study was carried out based on literature about the damages of seawall as tsunami protection structures and laboratory experiment reports. The destructions to the structures were divided into three classifications namely instantaneous direct destruction due to impact and drag forces, slowly direct destruction due to drag force, and slowly indirect destruction due to scour. Finally, important aspects to be considered in the design of seawall as tsunamis protection were proposed.

Abstract

The coastline is the boundary between the sea and land. Line changes are caused by abrasion and accretion. Abrasion and accretion occur throughout the coast of Laha so that the coastline undergoes quite drastic changes. This study aims to determine how much the average rate of abrasion and coastal accretion per year and how much the average area of abrasion and accretion for 10 years of recording data on the Laha coast. This study uses the remote sensing method as a rapid study to detect the rate of abrasion and accretion on Laha beach using Landsat 8 images in 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022 as primary data Calculation of shoreline changes using DSAS (digital shoreline analysis system) using the NSM (net shoreline movement) statistical method. The results of the 10-year coastal abrasion rate study occurred thoroughly on the coast of Laha beach. The highest abrasion occurred in 2018-2019 with an average value of NSM -15 cm/year while the highest accretion occurred in 2019-2020 with an average value of NSM +19.97 cm/year. Abrasion area for 10 years with an average value of NSM of -89.29 m2 / year while accretion for 10 years with an average value of NSM of +70.70 m2/ year. With the rate of abrasion that occurs, it is necessary to build coastal buildings evenly so that abrasion can be minimized.

Abstract

Dalam sistem irigasi, pengawasan dan pengendalian terhadap operasional jaringan irigasi secara teratur merupakan hal yang sangat penting. Untuk mewujudkan hal tersebut, dibentuklah sistem operasi dan pemeliharaan prasarana sumber daya air guna mencegah terjadinya kerusakan maupun penurunan fungsi. Pengelolaan ini dilakukan dengan mempertimbangkan prioritas penanganan terhadap kerusakan yang terjadi pada sistem irigasi. Berdasarkan prioritas tersebut, dilakukan evaluasi terhadap kinerja jaringan irigasi, mengingat sistem irigasi merupakan suatu kesatuan yang saling terintegrasi. Salah satu alat bantu yang digunakan dalam proses ini adalah e-PAKSI (Evaluasi Performa dan Kinerja Sistem Irigasi), yang berfungsi untuk mengolah data irigasi secara masif dan menghasilkan skala prioritas penanganan kerusakan berdasarkan indeks penilaian kinerja irigasi. Berdasarkan hasil evaluasi dengan metode ini, ditemukan bahwa kinerja irigasi terburuk berada pada Daerah Irigasi (D.I) Way Meten, yang mencakup empat saluran: saluran primer 1d Way Meten, saluran sekunder 1a Way Aha, saluran primer 1c Way Meten, dan saluran sekunder 1f Mako.

Abstract

The Way Ruhu River is one of the rivers in Ambon City, Maluku, empties into Ambon Bay, has a length of 8.37 km, and is one of the rivers that is prone to flooding. There have been several floods on this river and the most severe occurred in early August 2012 where flash floods occurred and caused considerable losses to the people living around the Way Ruhu River. The research location was carried out on the Wai Ruhu River in Ambon City - Maluku Province. Geographically, the Wai Ruhu River is located between 3°39'44.18" - 3°41'39" South Latitude and 128°11'49.06" - 128°13'46.47" East Longitude. The stages of this research are processing rainfall data, choosing the appropriate rainfall frequency distribution method. The distribution of rainfall frequency referred to in this case is the normal method, Gumbel, Normal Log and Pearson III Log. Testing the accuracy of the results of this method using the Chi Square method. Calculating the planned discharge using the HSS Nakayasu Method. Conclusions from the results of the analysis of the cross-sectional capacity of the Way Ruhu River using HEC-RAS, the highest water level considered is at point S14. At the 10 year discharge period, the flood height was 0.16 m with a discharge of 237.04 m3/sec, 25 years was 0.64 m with a discharge of 282.43 m3/sec, 50 years was 0.89 m with a discharge of 316. 69, 100 years with a discharge of 351.16 m3/s, and for 200 years of 1 m with a discharge of 385.10 m3/s. The solution to the capacity of the Way Ruhu River is to improve the river cross-section. It is necessary to carry out routine maintenance on the canal such as cleaning grass and rubbish because this can affect the storage capacity. There is a need to provide outreach to the community about the impacts caused by the overflow of the Way Ruhu River so that the community and the Regional Government can work together in maintaining and maintaining the infrastructure that has been built.

Abstract

Assessment of Beach Damage in Teluk Ambon Sub-district and Prioritisation of Handling. In the management of coastal areas, the assessment of the level of damage to coastal protective buildings is an initial planning step in controlling, preventing, protecting and restoring damage to land, infrastructure and public infrastructure in coastal areas. Assessment or evaluation of the level of coastal damage is needed to find locations of coastal damage that require immediate action. This research was conducted to assess the level of coastal damage and prioritize the handling of coastal protection buildings along the Teluk Ambon sub-district which consists of 8 districts / villages which are then divided into several segments. Each segment was separated by the estuary or edge of the coastal protection structures under review. This study starts by collecting data on damage to coastal structures, analyzing it, then weighing the level of damage and determining the priority of handling. The assessment was conducted in reference to the Circular Letter of the Minister of Public Works No. 08/SE/M/2010 on Guidelines for Beach Damage Assessment and Prioritization of Handling. The coastal damage parameters analyzed include damage/failure of coastal buildings with EA-2 code. The results showed that there were no beach buildings that suffered very heavy (ASB), very heavy (AB) and heavy (B) damage. Coastal buildings that experienced moderate damage (S) with less priority (D) were located in segment 4b of Laha Village. Coastal structures that suffered minor damage with no priority are in segments 1 to 4 of Hunuth Village, segments 1 to 5 of Poka Village, segments 1 to 3 of Rumah Tiga Village, Segments 1 and 2 of Wayame Village, segments 1 to 8 of Hative Besar Village, segments 1 to 4 of Tawiri Village, and segments 1 to 4a of Laha Village.

Abstract

The availability of clean water is a fundamental need that is crucial for the survival of all living beings, including humans. Katapang Hamlet, located in Lokki Village, Huamual District, West Seram Regency, faces serious issues related to the distribution of clean water due to frequent pipeline system failures, particularly caused by flooding. The pipeline system in this area has been built three times, but it continues to experience damage, affecting the clean water distribution to the community. The current system is highly vulnerable to natural disasters such as floods, with pipelines located in high-risk areas like riverbanks and steep cliffs, irregular pipeline routes, and inadequate system components. During floods, the community often goes without a clean water supply for days. To address this problem, a redesign of the clean water distribution network is required. This study aims to design an optimal clean water distribution system using Epanet 2.2 software. Through this application, the analysis and simulation of the distribution pipeline network are carried out to ensure that the system continues to function well, even during heavy rain or floods, so that the community can consistently receive a clean water supply. The results of this study are expected to provide a long-term solution to the clean water distribution problems in Katapang Hamlet.

Abstract

The Way Sikula River is one of the rivers in Ambon City with a length of 22.55 km. The Way Sikula River is in the Way Sikula and Air Manis watersheds. In July 2022, there was a flood downstream of the river which resulted in paralyzed road access to Ambon City and West Leihitu District. In this regard, it is necessary to analyze the profile of the flood water level in the river which is expected to become a flood control plan in the future. Calculation of flood discharge in the Way Sikula River for return periods of 2, 5, 10, 25, and 50 years used the rational method using rainfall data from the BMKG Pattimura Ambon station and Gunung Nona Ambon Post Station in 2012 - 2021. The results of the flood discharge calculation for the 2012-2021 period. 2nd, 5th, 10th, 25th and 50th year respectively are 99,51 m3/s, 130,47 m3/s, 150,36 m3/s, 168,87 m3/s and 192,74 m3/s. Floodwater profile analysis using HEC-RAS ver. 5.0.7. From the simulation results it is known that the Way Sikula River began to overflow at the Q2 year flood discharge in all simulated cross sections with a flood overflow height at a 50 year flood discharge reaching 1,86 meters.
