Land infrastructure such as a Power House (PH), a communication tower, and a Beach Manhole (BMH) is needed to sustain the system's power in order to survive. Therefore, the aim of this scientific paper is to study several alternative landing station locations in Pasangkayu, West Sulawesi and then determine the priority locations. The methods used to achieve these objectives are field observation methods and secondary data analysis based on parameters of land area conditions, environmental conditions, supporting infrastructure, social conditions and licensing systems, and marine activities. These aspects are then assessed to determine the priority of the selected location. The location selected based on the assessment carried out is ALT-02B. In succession, the three priority locations selected from the order of most priority to least priority are ALT-02B, ALT-02A, and ALT-06. This selected priority location is not necessarily the final choice location to be used in the construction of a tsunami early detection system land infrastructure because in the process there are still things to be considered and aspects that are made the main priority for consideration in making decisions.","PeriodicalId":270402,"journal":{"name":"Jurnal Alami : Jurnal Teknologi Reduksi Risiko Bencana","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129158759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Untuk untuk memberi rasa aman kepada masyarakat di calon ibukota baru tersebut nantinya akan dibangun sistem peringatan dini bencana tsunami. Selat Makassar terletak pada persimpangan tiga lempeng, yaitu Lempeng Indo-Australia, Lempeng Eurasia dan Lempeng Pasifik, menyebabkan tektonik dan kegempaan di kawasan tersebut sangat kompleks. Potensi tsunami di Selat Makassar baik berasal dari gempa maupun longsor bawah laut termasuk tinggi. Potensi tsunami yang disebabkan oleh gempa berasal dari megathrust Sulawesi Utara dan sesar-sesar naik yang berada di perairan Selat Makassar. Sementara longsor bawah laut diakibatkan oleh batuan tidak kompak pada morfologi curam serta longsor bawah laut akibat pergerakan sesar akibat goncangan gempa. Potensi longsor bawah laut sangat mungkin terjadi akibat longsornya endapan produk Delta Mahakam yang bermuara di Selat Makassar. Dalam merencanakan jalur kabel InaCBT diusahakan jalur kabel bisa melewati endapan Delta Mahakam yang berpotensi longsor bawah laut, memotong topografi terjal, memperhatikan kondisi batimetri, serta menyesuaikan master plan kabel laut dari Kementerian KKP. Alternatif rencana jalur kabel InaCBT di Selat Makassar yang paling baik dengan mempertimbangkan berbagai aspek tersebut adalah dari Kota Balikpapan – Kecamatan Sarudu (Kabupaten Pasangkayu).","PeriodicalId":270402,"journal":{"name":"Jurnal Alami : Jurnal Teknologi Reduksi Risiko Bencana","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129412881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are various configurations of trench placement in the field and this study aims to simulate the placement of trench by comparing the three trench configurations to find out which configuration is most effective in capturing surface runoff. The simulation is carried out by calculating the catchment capacity of surface runoff under different rainfall intensity conditions and runoff coefficients in the three trench configurations that have different catchment areas. From the calculation, it is known that configuration 3 in optimal conditions has a comparative advantage of 41.67% - 68.80% (compared to configuration 1) and 27.78% - 52.83% (compared to configuration 2). Meanwhile, configuration 2 has a comparative advantage of 13.89% - 16.06% when compared to configuration 1. From the calculation it is also known that there are conditions where the three configurations will produce a uniform value so that there will be no comparative advantage between the three configurations. This condition is generally above the rain intensity of 50 mm per hour and the runoff coefficient is above 0.45. \u0000 ","PeriodicalId":270402,"journal":{"name":"Jurnal Alami : Jurnal Teknologi Reduksi Risiko Bencana","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121259910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pada permukaan lereng komponen gravitasi yang bekerja pada tanah cenderung akan menggerakkan tanah ke bawah. Komponen gravitasi ini disebut sebagai gaya penggerak tanah. Lereng mempunyai perkuatan alami yang berasal dari komponen material tanah itu sendiri untuk melawan gaya penggerak tanah, sehingga gerakkan tanah atau kelongsoran tidak terjadi. Ada banyak metode analisis yang bisa digunakan dalam menganilisis kestabilan lereng, salah satunya adalah dengan menggunakan Metode Elemen Hingga (Finite Element Method). Permasalahan kestabilan lereng diselesaikan dengan Metoda Elemen Hingga dengan menggunakan program Plaxis 2D, dimana data analisis diperoleh dari hasil penelitian terdahulu. Data analisis merupakan kombinasi dari berbagai data analisis yaitu jenis tanah dan kemiringan lereng. Hasil analisis terdahulu dengan menggunakan program Slope-W untuk Potongan East (S-W Section), Potongan West (S-W Section), Potongan East HW (N-S Section), Potongan East LW (N-S Section) diperoleh model keruntuhan (collapse) dengan angka keamanan SF < 1.0 dan dibandingkan dengan Analisis dengan menggunakan Plaxis-2D, dimana nilai angka keamanan SF < 1 tidak bisa ditentukan. Berdasarkan analisa Slope-W diperoleh nilai SF < 1.0 (0.114) dan analisis Plaxis diperoleh nilai SF < 1 terjadi pada Potongan East (S-W Section), hal ini menunjukan bahwa Analisa dengan program Slope-W dan program Plaxis 2D mempunyai hasil yang sama dalam menentukan kemungkinan akan terjadi keruntuhan.","PeriodicalId":270402,"journal":{"name":"Jurnal Alami : Jurnal Teknologi Reduksi Risiko Bencana","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117063535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
