Abstract

Ruko Waingapu yang berlokasi di ruas Jalan Ahmad Yani merupakan tempat perbelanjaan padat di Waingapu yang tidak pernah sepi setiap harinya dari pengunjung dan pembeli karena menjual barang-barang kebutuhan pokok maupun sekunder yang lengkap. Hal ini mengakibatkan konflik terhadap lalulintas yang berada disekitarnya, yaitu diantaranya terjadinya penurunan kinerja ruas jalan akibat adanya aktivitas kendaraan berhenti atau parkir yang memiliki tujuan ke Ruko, kendaraan yang keluar masuk Ruko serta adanya aktivitas pejalan kaki menuju maupun keluar ruko.Tujuan penelitian ini adalah (1) Untuk menganalisis bangkitan pergerakan yang ditimbulkan oleh aktivitas di depan Ruko Waingapu (2) Untuk menganalisis kinerja ruas Jalan Ahmad Yani saat ini dengan dan tanpa adanya pengaruh bangkitan pergerakan di Ruko Waingapu. Dari hasil analisis diketahui: (1) Bangkitan pergerakan di Ruko Waingapu saat ini pada jam puncak tertinggi terjadi pada pukul 17.45-18.45 WITA yaitu sebesar 147 smp/jam. (2) Hasil analisis kinerja ruas jalan diketahui bahwa kapasitas ruas jalan sebesar 2066 smp/jam dengan derajat kejenuhan sebesar 0,25 pada jam puncak volume lalu lintas dan 0,25 pada jam puncak bangkitan pergerakan. Kecepatan yang terjadi ialah sebesar 13,72 km/jam pada jam puncak volume lalu lintas dan 13,7 km/jam pada jam puncak bangkitan pergerakan. Berdasarkan rasio Q/C dan kecepatan didapat tingkat pelayanan jalan tersebut terletak pada level F.

Abstract

Flowing water by pipe is mostly used to distribute the water from itssources to taps for various needs. On the way of distribution, it meets some obstacles,i.e.: velocity, surface and roughness changing. Thus, the research has been done inorder to know the influences of all the changes of the head loss on the 1 meter pipe.This research used Fluid Friction Apparatus complete with hydraulic bench andmanometer. Variation of flowing on pipe has done for 50 times, using each 6 mm and10 mm and four 17.5 mm pipe with different roughness which consist of differentsands diameter.From that research we found out that there’s a similarity in velocity and roughnesswith head loss showing polynomial order 2 ( hf = a + bu + cu2 and hf = a + bk + ck2 )where much velocity and roughness causing higher head loss. While pipe surfaceinverse proportional to head loss that shows exponential relationship (hf = a e –bA)where more surface causing less head loss.

Abstract

Abstract: Behavior analysis and performance evaluation of frame structures with infilled wall (RDP) has been done by making four structure models, a model of open framework (MOF) and three RDP models (M1, M2, and M3). In the RDP models, walls in transverse direction of the building was placed fully on the floor 2, 3 and 4, and varied on the ground floor. The wall in longitudinal direction, however, was not included in the model because of the holes and irregularity. The walls on the ground floor were placed fully for M1, at the ends and middle of the building for M2, and none for M3. The walls were modeled as 3 diagonal struts that can withstand compressive stress only. The behavior of the structure was observed through linear elastic analysis by comparing story drift and its ratios, while the performance of the structure was evaluated through nonlinear static Pushover analysis using SAP2000. The analysis showed that the inclusion of infill walls in the model increases the stiffness of the structure. The values of drift at roof level were 8 mm, 10 mm, 12 mm and 28 mm for M1, M2, M3, and MOF, respectively. Soft story mechanism was detected in the RDP models with irregular wall placement with maximum drift ratio of 157% and 249% for M2 and M3, respectively, while MOF and M1 with continuous wall have drift ratios of 101% and 92%. Discontinuous walls also decrease performance of the structure. Pushover analysis results in the transverse direction showed that M1 is capable of resisting the largest base shear force 658 tons with a level of performance Operational (O), while M2 with O performance levels capable of resisting base shear of 437 tons. M3 and MOF can resist the lowest base shear force of 270 tons and 279 tons with performance level of Immediate Occupancy (IO) and Life Safety (LS). Pushover analysis in the longitudinal direction of the building (where the wall was not modeled) showed that, MOF can resist the least base shear compared to the three RDP models. This suggests that the struts on the transverse direction also affect the stiffness of the structure in the longitudinal direction. The actual value of ductility in the transverse direction of the structure are 4.6; 2.9; 2.8; 3.4; for MOF, M1, M2 and M3, respectively. While in the longitudinal direction the ductility are 3.2; 3.6; 3.8; 3,9. All models ductility values are smaller than the design value, i.e., µ = 5.

Abstract

Tanah yang terdeposit di alam akan memiliki struktur tanah secara alamiah. Struktur tanah akan memberikan ciri pada parameter sifat fisik dan mekanik tanah. Tanah dapat mengalami kerusakan struktur alamiahnya karena aktivitas/gangguan luar seperti pembebanan dan gangguan mekanik, misalnya pengambilan contoh tanah (sample). Tanah yang mengalami kerusakan struktur (remolded) akan kehilangan sebagian besar dari kemampuannya dalam memberikan respons mekanik atau daya dukung serta perilaku pemampatannya. Untuk mengembalikan kondisi struktur tanah yang telah rusak dengan cara alamiah, dibutuhkan waktu geologi yang sangat lama. Pada penelitian ini, dilakukan upaya pembentukan struktur tanah buatan dengan merekayasa pertumbuhan struktur tanah dengan menambahkan bahan aditif. Tanah remolded berupa lempung hasil fabrikasi dicampur dengan bahan semen dengan variasi kadar tertentu. Campuran semen dan tanah lempung dengan kadar air pada batas cair dibentuk sebagai benda uji dan diberikan beban pra-konsolidasi dalam kurun waktu tertentu. Uji konsolidasi satu dimensi dilakukan pada seri benda uji sesuai dengan kadar aditif dan waktu pembebanan pra-konsolidasi. Hasil uji indeks pemampatan, cc untuk variasi kadar semen 0%; 0,5%; 1%; 3% dan 6% adalah 0,41; 0,44; 0,49, 0,61 dan 0,62 Sedangkan uji indeks pemampatan pada benda uji tanpa aditif yang diberikan beban pra-konsolidasi 25 kPa dengan lama waktu pembebanan 2, 30, 45, 60, dan 80 hari memberikan hasil pada kisaran 0,34. Kata kunci: struktur tanah, kerusakan struktur, remolded, konsolidasi, indeks pemampatan.

Abstract

Pesisir merupakan wilayah yang sangat rentan terhadap berbagai bencana yang datang dari laut, salah satu bentuk bencana tersebut adalah kerusakan pantai (erosi). Untuk menanggulangi masalah tersebut perlu dilakukan  mitigasi bencana dengan mereduksi serangan gelombang dan arus sebagai penyebab utama erosi. Hingga saat ini penangulangan kerusakan pantai membutuhkan biaya yang sangat besar, sehingga perlu adanya inovasi perlindungan pantai yang ramah lingkungan dan biaya murah supaya garis pantai di Indonesia bisa tetap terjaga. Penelitian ini dilakukan dengan mengaplikasikan sistem pelindung Eco-hybrid (kombinasi antara serabut kelapa dan vetiver) untuk  merestorasi kerusakan pantai dengan berbasis material lokal serta mudah dalam pemasangan dan perawatan. Digunakannya rumput vetiver dikarenakan mempunyai perakaran yang kuat dan mampu menstabilkan daya dukung tanah dengan akarnya yang menyatu dengan tanah dan menambah kuat tarik tanah (komposit). Fungsii dari serabut kelapa dalam penelitian ini adalah sebagai tempat penyimpanan cadangan air bagi vetiver selama awal pertumbuhan. Parameter efektifitas rekayasa eco-hybrid ini diamati dengan mengukur laju pertumbuhan akar vetiver dan peningkatan kuat geser tanah. Hasil penelitian yang dilakukan, dapat disimpulkan bahwa vetiver mampu tumbuh dengan baik dengan tingkat ketahanan vegetasi yang bagus dan belum terjadinya biodegradasi material serabut kelapa,  dan terjadi sedimentasi di sepanjang garis pantai tempat vetiver ditanam.

Abstract

Abstract: This study investigates the influence of household income on both car and motorcycle ownerships in the city of Denpasar using a Multinomial Logit Model. The household income is about 61%, 17% and 61% more likely to influence a household owning 1 motorcycle and 1 car, 2 or more motorcycles and 0 car, and 2 or more motorcycles and 1 car respectively than 1 motorcycle and no car. The probability of both car and motorcycle ownerships increases substantially by more than 4% in the next 20 years if household income in Denpasar city rises. This is particulary applied for the household owning 1 motorcycle and 1 car and 2 or more motorcycles and 1 car. The probability of a household owning 1 motorcycle and no car ownership however, drops significantly by almost 10% in the next 20 years if household income in Denpasar city increases. Consequently, the household income significantly influences both car and motorcycle ownerships in the city of Denpasar. A huge number of car and motorcycle uses on the road continously leads to serious transport problems in the city of Denpasar for the next few years. This is related to the negative impacts of transport in particular road safety and environmental impact. Improving the existing public transport and introducing a high quality public transport service within and to/from Denpasar city is urgently required. The fare of such high quality public transport service in Denpasar city however, must be sufficiently low to compete with the cost of riding a motorcycle. In addition, a significant amount of fare subsidy from both local and central government is considerably required
