The Saddle is 200 m in length with top elevation is 162 m to 165 m and 150 in width. The solution of the problem is necessary Saddle Dam construction by using embankment material. Based on geology map in the location is that Saddle Dam laid on kerek formation with soil classification of loam and susceptible for sliding. The existing soil must be changed by good soil properties to guarantee the stability. This study descripts about Saddle Dam stability analysis by using finite element method. The result shows that factor of safety of Saddle Dam is 2.96, therefore Saddle Dam is stable and safe.</em></strong></p> 2022-06-30T00:00:00+00:00 Copyright (c) 2022 Journal of Disaster Mitigation and Civil Engineering Research Analisis Ancaman Bencana Gelombang Ekstrem dan Abrasi di Wilayah Pesisir Gresik Jawa Timur 2022-12-23T02:57:56+00:00 Azril Reza Tri Septian Noverma <p><strong><em>Coastal areas are vulnerable to disaster hazard, one of them is the hazard of Extreme Waves and abrasion.

The disaster needs to be mitigated as part of preventing sustainable disasters. Disaster mitigation as a form of protection to reduce disaster risk, can be done with hard structure and soft structure. The case study of this research is Bedono Village, Sayung Subdistrict, Demak Regency, whose condition is increasingly worrisome, starting from the sinking of the house to the loss of land/ residential areas. This research was conducted with a qualitative descriptive analysis method. In the initial stages of field observations, the distribution of the questionnaire was then analyzed based on literature studies. The results of the study concluded that the community has knowledge about disasters having a score of 3.55 (good), while about attitudes towards disaster have a score of 2.32 (not good). And the community wants mitigation of soft structures with a value of 3.74 (Very good/ Strongly agree). So that the role of disaster mitigation is not only done in a hard structure, but also must consider soft structure mitigation.</em></strong></p> 2022-06-30T00:00:00+00:00 Copyright (c) 2022 Fajar Setiawan Pengaruh Variasi Penambahan Abu Ketel (Ash Boiler) Terhadap Nilai Kuat Tekan Mortar 2022-12-23T03:11:57+00:00 Ahmad Shofi Arqowi Pribadi Dian Rizky Adinda <p><strong><em>Kettle ash is the solid waste left over from burning bagasse. Boiler ash which can be used as a substitute for cement is planned to reduce pollution and greenhouse gas emissions such as CO<sub>2</sub> from the cement industry. Due to the high SiO<sub>2</sub> content of the boiler ash, it is expected that the ash will improve the quality of the mortar mix. Mortar composition with cement 1:4 using kettle ash instead of cement. This study aims to replace cement in the manufacture of mortar in the amount of 0%, 5%, 15% and 25%. Because it is equivalent to mortar that does not contain boiler ash, the compressive strength test results on a mixture containing 5% boiler ash are the best.

This study will use Mike21 software to investigate changes in sedimentation on islands I, J, and K during the east and west monsoons. The impact of reclamation and high TSS will change current and sediment patterns. The results of this study indicate that in the east season the current direction when the tide is moving east and during low tide the current moves westward with an average current speed of 0.103097 m/s, during the west season the current direction moves west during high tide and to the east at low tide with an average current speed of 0.072885 m/s. The results of the sedimentation modeling show that sediments during the east monsoon move eastward with SSC values reaching 1.19 kg/m<sup>3</sup> in post-reclamation and 1.82 kg/m<sup>3</sup> in pre-reclamation and in the west monsoon sediments will move west with SSC values reached 1.71 kg/m<sup>3</sup> during post-reclamation then pre-reclamation the highest average distribution of SSC reached 1.42 kg/m<sup>3</sup></em></strong></p> 2022-06-30T00:00:00+00:00 Copyright (c) 2022 Bramadica Primadoni Putra Hariyanto, Asri Sawiji, Rizqi Abdi Perdanawati
