Abstract

ABSTRAKTebing sungai merupakan daerah yang rawan terhadap erosi yang diakibatkan oleh aliran air. Erosi yang berlangsung terus menerus mengakibatkan longsor. Secara umum, jenis tanah di Kabupaten Bogor didominasi oleh latosol yang mudah erosi, selain itu dikarenakan curah hujan yang tinggi dan juga meningkatkan risiko longsor. Salah satunya adalah kejadian longsor pada tebing Sungai Ciliwung pada ruas Kampung Legok Nyenang RT.01//03, Desa Leuwimalang, Kecamatan Cisarua. Panjang longsoran mencapai 27 meter dengan ketinggian 10,20 meter. Struktur dinding penahan tanah diperlukan untuk mencegah terjadinya longsor yang lebih luas lagi. Mempertimbangkan kondisi lereng dan parameter fisis tanah, maka direncanakan dinding penahan tanah jenis kantilever untuk wilayah ini. Hasil analisis metode Mononobe-Okabe menunjukkan nilai keamanan dinding penahan tanah terhadap geser sebesar 0,36, dan terhadap guling sebesar 0,21, angka keamanan tersebut lebih rendah dibandingkan angka keamanan yang disyaratkan, yaitu 1,5 dengan demikian dinding penahan tanah rencana tidak kuat menahan tekanan tanah yang ada di belakangnya. Oleh karena itu, kekuatan dinding sepenuhnya dialihkan ke tanah dasar, dengan menggunakan fondasi bored pile. Hasil analisis daya dukung tanah, diperoleh nilai kapasitas ultimit aman (qs)sebesar 223,93 kN/m2 yang lebih besar dibandingkan nilai total beban vertikal, yaitu 204,52 kN/m2, sedangkan kapasitas ijin satu fondasi mencapai 569.89 kN.Kata Kunci: Sungai Ciliwung, tebing, longsor, dinding penahan tanah, kantileverABSTRACTRiverbanks as areas prone to erosion caused by water flow. Continuous erosion causes landslides. In general, soil types in Bogor Regency are dominated by latosols which are easily eroded, apart from that it is due to high rainfall and also increases the risk of landslides. One of them is a landslide incident on the cliffs of the Ciliwung River on the section of Legok Nyenang RT.01 / 03, Leuwimalang Village, Cisarua District. The length of the landslide reached 27 meters with a height of 10.20 meters. The structure of the retaining wall is needed to prevent more extensive landslides. Considering the slope conditions and physical parameters of the soil, a cantilever-type retaining wall is chosen for this area. The results of the analysis Mononobe-Okabe method show that the safety value of the retaining wall against shear is 0.36, and against rolling is 0.21, This safety figure is lower than the required safety figure, which is 1.5, thus the retaining wall of the planned soil is not strong enough to withstand the ground pressure behind it. Therefore, the strength of the walls is completely transferred to the subgrade, using a bored pile foundation. The results of the soil bearing capacity analysis showed that the ultimate safe capacity (qs) value was 223.93 kN /m2 which was greater than the total vertical load value, which was 204.52 kN /m2, while the permitted capacity of one foundation reached 569.89 kN.Keywords: Ciliwung River, cliffs, landslides, retaining walls, cantilever.

Abstract

Abstrak: Pengemudi mobil truk memilih jalan tol dengan mempertimbangkan faktor-faktor, yaitu faktor jarak dari asal ke gerbang tol, waktu perjalanan, biaya perjalanan, kemacetan, tempat peristirahatan yang tersedia dan variabel yang sangat sensitif ialah variabel kemacetan. Berdasarkan hasil data yang telah diuji dengan SPSS maka didapatkan model persamaan : Ujt = -0,441*(Jarak Gerbang Tol)-2,449*(Waktu Perjalanan)-0,820*( Biaya Perjalanan)-1,975*(Kemacet an)-0,957*(Pemberhentian). Model persamaan analisis biaya & waktu yaitu : Ujt = 0,414-0,28*(Biaya)-0,057*(Waktu).ABSTRACTEvery Traveler tries to find the best route to minimize travel costs like reducing travel time by considering a few factors. These reasons are the basis for consideration of route selection. That’s why necessary to conduct research on Trans Sumatera Toll Roads and Non-Toll Public Roads to determine the factors that influence the decision of truck drivers to determine the most efficient road route in terms of time and from and economic perspective. The data analysis used in this study is Binary Logistic Statistical and analysis method using IBM SPSS Statistics Software. The result of the study show, Truck drivers choose Toll Roads by considering Distance of Toll Gate, Travel Time, Travel Costs, Congestion and Rest areas. The values of these factors: Distance Of toll Gate -0.441, Travel Time -2.449, Travel Costs -0.820, Congestions -1.975, Resting Place -0.957. The most influencing factor is congestion, the model obtained is Ujt = -0.441 * (Toll Gate Distance) - 2.449 * (Travel Time) - 0.820 * (Travel Expenses) - 1.975 * (Congestion) - 0.957 * (Rest areas). The results of sensitivity test between cost and time is, truck drivers more sensitive against the time variable, the model obtained is Ujt = 0,414 – 0,28 * (Cost) – 0,057 * (Time)Keywords: driver behaviour, travel routes, Toll roads, Non-Toll public roads, route choice, Binary Logistic Method.

Abstract

ABSTRAKPemecah gelombang selama ini hanya dikenal sebagai salah satu struktur pelindung pantai terhadap erosi dan abrasi. Meskipun demikian ada fungsi lainnya, yaitu sebagai pelindung daerah pelabuhan dari gangguan gelombang. Pemecah gelombang memiliki kemampuan mengurangi tinggi gelombang dengan cara memecahkan gelombang melalui pori-pori batuan penyusunnya. Tulisan ini bertujuan untuk melakukan tinjauan literatur terhadap jenis dan fungsi pemecah gelombang, serta aplikasi pemecah gelombang di Indonesia. Dalam tulisan ini dikemukakan 2 (dua) jenis pemecah gelombang, yaitu: pemecah gelombang tenggelam, dan pemecah gelombang tidak tenggelam serta solusi alternatif berupa penggunaan pemecah gelombang terapung.Kata Kunci: Pemecah gelombang, pelindung pantai, aplikasi pemecah gelombang.ABSTRACTBreakwaters are known as one of the coastal protection structures against erosion, abrasion, and protection of the port area from wave disturbances. The breakwater can reduce wave height by breaking the wave through the pores of the constituent rock. This paper aims to conduct a literature review on the types and functions of breakwaters, as well as the application of breakwaters in Indonesia. In this paper, 2 (two) types of breakwaters are discussed: submerged breakwater, and detached breakwater. An alternative solution is proposed, a floating breakwater.Keywords: Breakwater, coast protection, breakwater application.
