Abstract

Abstrak Analisis skripsi ini bertujuan untuk mengetahui aman atau tidaknya bangunan pengaman pantai yang berada di Bambaloka Kabupaten Pasangkayu, terhadap stabilitas kuat dukung tanah, geser dan guling dan studi ini bertujuan untuk mengetahui tipe bangunan pengaman pantai yang cocok untuk pantai Bambaloka. Dari hasil yang di dapatkan berdasarkan analisis yang di lakukan dapat di simpulkan beberapa hal mengenai analisis stabilitas bangunan pengaman pantai ( Breakwater ) yang berada pada pantai Bambaloka, Kecamatan Baras Kabupaten Pasangkayu, Sulawesi Barat. Dapat di simpulkan sebagai berikut, Gaya terhadap gelombang, = 0,7 m, = 0,17 m, Stabilitas bangunan pengaman pantai terhadap kuat dukung tanah = - 44,4 kN/m² < = 7,393 kN/m² ( Aman ) Stabilitas Pemecah Gelombang terhadap geser dan penggulingan Terhadap geser = 0 < 2 ( Aman ) Terhadap guling = 0,116 < 2 ( Aman ). Kata Kunci : Analisis, Breakwater, Geser, Guling, Stabilitas, Pengaman Pantai. Abstrak The analysis this thesis aims to determine whether or not a safe beach building located in Bambaloka Pasangkayu Regency, to the strong stability of soil support, shear and rolling and this study aims to determine the type of beach safety building suitable for Bambaloka beach. From the results obtained based on the analysis carried out, it can be concluded that there are several things concerning the stability analysis of the beach safety building (Breakwater) located on the coast of Bambaloka, Baras District, Pasangkayu Regency, West Sulawesi. It can be summarized as follows, force against wave, l_c = 0.7 m, l_t = 0.17 m, stability of coastal protection building against soil bearing strength σ_maks = - 44.4 kN / m² <q_a = 7.393 kN / m² (safe ) Stability of Breakwaters to shear and rolling Against shear = 0 <2 (Safe) Against rolling = 0.116 <2 (Safe). Keywords : Analysis, Breakwater, Slide, Bolster, Stability, Beach Safety.

Abstract

Sedimentasi di wilayah hulu sungai dapat menurunkan efektivitas fungsi bendung. Penelitian ini bertujuan untuk memodelkan angkutan sedimen dasar di hulu Bendung Sekka-Sekka, Kabupaten Polewali Mandar, menggunakan perangkat lunak HEC-RAS versi 6.6.1. Pendekatan yang digunakan adalah kuantitatif melalui simulasi numerik. Data diperoleh melalui survei lapangan, pengambilan sampel sedimen dasar, serta uji laboratorium berupa analisis saringan dan pengujian berat jenis. Data tersebut digunakan sebagai input pemodelan untuk mensimulasikan proses transportasi sedimen. Hasil simulasi menunjukkan bahwa titik RS 115.00 mengalami lonjakan kecepatan aliran dan tegangan geser pada awal Agustus 2024, yang menyebabkan peningkatan akumulasi sedimen secara signifikan. Temuan ini menunjukkan bahwa wilayah hulu memberi kontribusi besar terhadap sedimentasi di bendung. Pemodelan ini memberikan gambaran kondisi nyata transportasi sedimen dan menjadi dasar dalam merancang strategi pengendalian. Rekomendasi strategi pengelolaan meliputi pengerukan berkala dan pembangunan bangunan pengendali sedimen di hulu. Hasil penelitian ini diharapkan dapat menjadi acuan dalam pengelolaan daerah aliran sungai secara berkelanjutan untuk menjaga fungsi bendung dan mendukung sistem irigasi yang efisien di wilayah sekitarnya

Abstract

Despite being equipped with mud pockets, the Sekka-sekka Dam still requires routine maintenance due to sediment accumulation in the Primary Canal. Sediment modelling has become an effective approach to identify areas with high sedimentation to make maintenance more focused and efficient. This research aims to determine the sedimentation patterns that occur, model the transport of bed sediment, and analyse the magnitude of bed sediment transport in the D.I Maloso primary canal using Hec-Ras software. The analysis was conducted using a Quasy-Unsteady Flow approach, with input comprising cross-sectional data of the canal, a flow discharge of 33.81 m3/s, and the characteristics of the bed sediment. The simulation results indicate the presence of sediment transport along the canal, with a dominance of fine sand and medium sand fractions. The total sediment transport over one month in the upstream reached 14,551 kg/month with a sediment thickness of 0.00227 m, in the midstream 35,351 kg/month (0.00551 m), and downstream 23,791 kg/month (0.00371 m). The shear stress values were 0.0080 Pa, 0.0078 Pa, and 0.0076 Pa respectively, with a fall velocity of 0.26 m/s upstream, and 0.2 m/s in the midstream and downstream. The average sediment concentration over three months was 0.3 mg/l, with the highest concentration recorded downstream at 4.8 mg/l. This modelling demonstrates the distribution of transported sediment in the canal, with the highest accumulation downstream due to the decrease in flow velocity and shear stress.
