Oleh karena hal itu kunjungan keluar masuk kapal dalam dan luar negeri harus dilakukan dengan seksama dan terekam secara baik. Back Propagation merupakan simulasi buatan yang dibuat berdasarkan system kerja jaringan syaraf tiruan. Simulasi ini meniru data input yang dimasukkan sehingga menghasilkan data output yang mendekati hasil dari data input. Simulasi ini juga memiliki kecanggihan berupa menirukan data range yang berada diantara data input. Sehingga memudahkan dalam memprediksi data yang tidak ada didalam data input. Data kunjungan kapal dalam dan luar negeri diambil dari data Badan Pusat Statistik Sumatera Selatan dari tahun 2019 sampai 2021. Hasil simulasi Back Propagation untuk data kunjungan dalam negeri yang menghasilkan eror terkecil 0,92% dengan trial epoch sebanyak 175693 dan mengalami eror data di 53%. untuk data kunjungan luar negeri yang menghasilkan eror terkeci 1,44% dengan trial epoch sebanyak 189367 dan mengalami eror data di 73%.

Khususnya kota Bandung yang merupakan pusat pariwisata di wilayah Jawa Barat. Salah satu akses menuju tempat pariwisata di Kota Bandung dan merupakan ikon Kota Bandung. Disamping itu, Jalan Ir.H Juanda memiliki permasalahan yaitu tingkat kemacetan yang tinggi dan banjir pada musim penghujan. Sepuluh tahun terakhir kawasan Jalan Ir.H. Djuanda selalu banjir jika terjadi hujan deras. Hal ini menyebabkan genangan air masuk ke ruas Jalan Ir.H Juanda yakni dari Pasar Simpang menuju Terminal Dago. Hal ini berdampak pada kerusakan jalan, drainase, dan kemacetan. Untuk mengetahui risiko terjadinya luapan saluran pada wilayah kajian sebagai akibat berbagai besaran debit banjir, dilakukan analisis metode safety factor dan first order-second moment. Hasil analisis menunjukkan terdapat 2 titik yang memiliki peluang untuk terjadinya luapan yaitu di lokasi Masjid Al-Ihsan dan Bengkel Honda. Solusi yang diberikan untuk mengatasi hal tersebut adalah melakukan normalisasi drainase dengan ukuran 1.5 m x 1.5 m dari hulu hingga hilir. Hasil menunjukkan bahwa keandalan saluran meningkat menjadi 92.96 % (Q2), 88.54 % (Q5) dan 85.81 % (Q10) untuk saluran Masjid Al-Ihsan serta 100 % (Q2), 99.98 % (Q5) dan 99.92 % (Q10) untuk saluran Bengkel Honda. Metoda pada analisis risiko di atas dapat menghubungkan probabilitas kegagalan atau pelampauan dengan harapan keberhasilan fungsi suatu struktur penampang drainase dalam menampung aliran banjir.","PeriodicalId":430468,"journal":{"name":"Bulletin of Civil Engineering","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134403884","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}

Therefore, Jenelata Dam is planned to be built in South Sulawesi with a watershed area of 221.22 km2. Every dam has a dambreak potential due to many factors such as earthquakes. Risk analysis is carried out in order to study the most effective mitigation plan on minimizing the risk index. Flood hydrograph modeling due to dambreak is done using HEC-HMS with the most extreme dambreak scenario is due to overtopping with a discharge peak of 48726.47 m3/s. The flood inundation modeling is done using HEC-RAS with the inundation area due to overtopping was 20842.48 Ha. The results of the inundation map and demographic data are then used as the basis for determining the risk index per sub-district. The mitigation plan is in the form of structural and non-structural. The structural solution was determined through testing the effectiveness of every solution on reducing the flood inundation area, where the installation of embankments with 150 cm high on the main and river branch give the best result. Implementation of the mitigation plan is based on the risk index value of the sub-district and its components. The final result is a risk index with implementation of the mitigation plan as a comparison to the risk index without the mitigation plan. The result obtained is a decrease in the risk index on several sub-districts from high to medium or medium to low.","PeriodicalId":430468,"journal":{"name":"Bulletin of Civil Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125747889","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 penelitian ini akan memberikan gambaran penggunaan BIM sebagai konsepnya sampai dengan pemodelan 3D (dimensi) pada konstruksi struktur penuh pada sebuah proyek gedung X dengan menggunakan software Tekla Structures Student License. Kemudian dilanjutkan dengan membandingkan perhitungan volume struktur dengan Microsoft Office Excel dengan QTO (Quantity Takeoff) dari Tekla Structures yang akan menghasilkan rencana anggaran biaya dari kedua metode tersebut. Hasil penelitian ini perbandingan volume menghasilkan selisih untuk struktur bawah beton 0% dan besi 1% atau lebih efisien menggunakan metode konvensional. Untuk struktur atas selisih beton 0,28%, besi 1,1% dan bekisting 0,22% atau bisa dibilang disemua selisih tersebut lebih efisien perhitungan menggunakan metode BIM. Sedangkan, struktur atap memiliki selisih jurai 3,39%, gording 0,4%, usuk 1,23% dan reng 0,42% atau bisa dibilang selain perhitungan reng saja yang lebih efisien dihitung menggunakan metode BIM. Lalu perhitungan biaya didapat nilai selisih untuk struktur bawah sebesar 0,48% atau sebanyak Rp 1.452.861 struktur atas sebesar 0,58% atau sebanyak Rp 14.078.298 dan struktur atap sebesar 1,4% atau sebanyak Rp 6.795.712.

Puddles that do not enter or are hampered can cause damage to the road. This can be overcome by the inlet design of the road drainage channel that is suitable for the conditions in the field. By paying attention to the distance between inlets, dimensions, and inlet types adjusted to the rainwater discharge and the width of the existing road. Street Inlet is a hole on the sides of the road that serves to accommodate and distribute rainwater runoff along the road leading into the drainage channel.The research was carried out on a prototype that describes the condition of the highway with street inlet modifications such as conditions in the field. The method of analyzing surface runoff in the use of rational methods, inlet dimension analysis is used in the applicable hydraulic rules. The input data used are rainfall data, type of road, type of inlet street, rain runoff or inundation, drainage channel conditions, linear regression. This study discusses the performance of the road inlet to reduce inundation due to rain runoff (with a model of a rectangular inlet on the shoulder of the road). In the research carried out the type of inlet that will be used is the gutter inlet which has a horizontal opening.
