Abstract

Utilization of Littoral develops continuously along with economic developments and technological advancements nowadays. Therefore, special attention is needed to overcome the problems that may arise in Littoral including coastal areas. One of the most popular beach problems for this time is the unbalanced sediment transport causing Coastal Erosion. The retreat of shorelines is generally due to coastal processes such as erosion and abrasion that will harm either the local population or life sustainability.From Sindulang Beach until Tumumpa II region where is located on Boulevard II experiencing erosion and abrasion. This certainly cannot be ignored for long because besides it will be able to damage the facilities and infrastructure of society and other public infrastructure but it also can harm the lives of coastal communities.Through this paper, The Author tries to do new thing by placing breakwater as a building that has an influence on sediment transport.  We know usually The Breakwater is a Shore protector for the wave attacks, this time we try to see its effect on the sediment transport. Through this study, The Author conducts the modeling of coastline with four variations of breakwater. First Variation: The breakwater is placed in parallel against the west-east direction separately, Second Variation: the breakwater is placed in parallel against the shoreline separately but it is longer than the First Variation, Third Variation: the breakwater is placed in parallel against coastline with tightly placed and longer than First Variation, Fourth Variation: breakwater is placed in parallel against the coastline with very tightly placed and longer than First Variation. The Differences in length of breakwater causes the difference of sediment transported too. In the First Variation, sediment is transported up to 12370 m3 to the right, Second Variation; sediment is transported up to 17589 m3 to the right, Third Variation; sediment is transported up to 22682 m3 to the right, Fourth Variation; sediment is transported up to 11478 m3 to the right. Then we found the configuration of the Second Variation of breakwater beach building is most efficient. The calculation of the effect of groins on shoreline is done with Genesis Software. Before using Genesis for modeling, the Genesis should be calibrated to the calibration parameters K1, K2 and d50 afterward doa Sensitivity Test. After the Test, take the value that produces the smallest DYrms among The values of K1, K2 and d50.  The values of K1, K2 and d50 are 0.11, 0.2 and 0.5 mm. The data that must include in the genesis are wave data, initial and measured coastline, offshore depth and depth of cover. Wave data is obtained from wind data analyzed by SMB method. The wave data that include in Genesis are the period, height and direction of the wave where the wave height that include in this case is the average wave height. Keywords: Breakwater, Sediment Transport, Sindulang-Tumumpa Beach 2.

Abstract

The successful implementation of construction projects can be seen from the accuracy of cost, time and quality. In an effort to control the potential risks need to be done risk identification comprehensively, in the analysis and then controlled, so it can reduce the opportunities and consequences of risks that will occur. The changes occurring in the project implementation phase then have an impact on the performance of the project, whether it be at the cost, quality, time and scope of work, which may pose a risk. As for the risk that there is something that can be tolerated by the owner so as to get additional costs or time and unisolable by the owner (non-excusable scope) so that all the consequences borne by the contractor. As for the purpose of this study is able to identify non-excusable change factors that have a dominant risk in the implementation phase of private building development projects in Manado which resulted in changes in project implementation performance, knowing the impact of any non-excusable change factor, and get the risk model generated from this research includes the mitigation of such risks.The research methodology used is to use quantitative method for data collection of the first stage which is analyzed by using SPSS, then qualitative method supported by survey and questionnaire for data collection stage 2 in analysis with SPSS. 23 is then used AHP (Analytic Hierarchy Process) method to determine the risk level.The results of the study aimed to obtain the non-excusable risks that are dominant in the implementation project of private building development in Manado city are as follows: 1) Using local workforce. 2) The owner likes to change to work image. 3) Many changes by the owner to the image. 4) Short execution time. 5) Morale and low work motivation.From the results of this study can be concluded that there are factors - scope non excusable change which has the risk of impacting changes in the performance of private construction projects in the city of Manado both in terms of cost performance, time, and quality. From the results of the study there are relationships (influence) risk factors that impact on changes in time and cost performance of private construction projects in Manado. The risk mitigation that must be made to mitigate the dominant negative risks in this study is one of the highest using local labor, by reducing the risk of recruiting known or known local laborers, coaching and briefing before work on targets and quality of work, awarding rewards to workers who meet the required criteria, making good contracts, evaluating work periodically, recruiting management personnel on reliable projects. May then transfer the risk or transfer the risk that will occur. Keywords: risk model, non excusable risk, private project performance

Abstract

Kemampuan sebuah jembatan beton prategang dalam memikul beban terutama pada struktur atas sangat dipengaruhi oleh kekuatan girdernya. Girder profil I merupakan bentuk yang paling banyak digunakan untuk pekerjaan balok jembatan. Direncanakan sebuah jembatan prestressed dengan metode post tension yang menggunakan girder profil I sebagai struktur utamanya. Kabel prestress yang digunakan adalah jenis strands Uncoated 7 wire super strands ASTM  416 Grade 270 Low Relaxation. Balok prategang ditinjau sebagai fully prestressed. Perencanaan dilakukan dengan dua model perencanaan, model perencanaan yang pertama adalah memvariasikan bentang jembatan, dimensi girder profil I, serta jumlah tendon yang digunakan. Sedangkan model perencanaan yang kedua adalah dimensi girder profil I dipertahankan dan penggunaan tendonnya dioptimalkan (hanya digunakan 2 tendon untuk masing-masing bentang jembatan). Girder profil I prestressed untuk bentang jembatan 20 m adalah b = 0.47 m dan h = 0.95 m, dengan Pt = 3745 kN, nt = 2 tendon serta ns = 30 strands, dimensi girder profil I prestressed untuk bentang jembatan 30 m adalah b = 0.60 m dan h = 1.36 m dengan Pt = 6026 kN, nt = 3 tendon serta ns = 48 strands. Jika dimensi girder profil I dipertahankan dan penggunaan tendonnya dioptimalkan (hanya digunkan 2 tendon saja), maka diperoleh Pt = 6150 kN, dan ns = 46 strands, dimensi girder profil I prestressed untuk bentang jembatan 40 m adalah b = 0.80 m dan h = 1.74 m dengan Pt = 9415 kN, nt = 4 tendon serta ns = 72 strands. Jika dimensi girder profil I dipertahankan dan penggunaan tendonnya dioptimalkan (hanya digunakan 2 tendon saja), maka diperoleh Pt = 9500 kN, dan ns = 70 strands. Kata kunci :  Jembatan, Beton Prategang, Girder Profil I, Post Tension, Fully Prestressed, Variasi Bentang.

Abstract

In the science of traffic engineering, there are many methods of measuring queues and delays. Some of these methods are queuing theory and shockwave analysis. From these two methods will be compared the most ideal characteristics to analyze the queue and delay. The Methods in this research used primary data collected from Megamas Area through by manual survey method to analyze shockwave and queuing theory. The results obtained the following conclusions: (1) The shockwave analysis at the exit gateway counter are formed by Greenshields’s basic chart and  present the queue length, total duration of the counter opening for the last vehicle entering the queue, and total duration from opening of the counter to the normal condition will increase linearly with increasing incidence duration, while the delay will increase exponentially. (2) In queue theory analysis, existing counters are still capable for serving the vehicles, this is obtained from the average value ρ <1 (eligible) only at certain periods that have value ρ> 1. Based on analysis, the service level on all counters are strongly influenced by the speed and accuracy of service door operators, readiness of reserve money for returns, readiness of drivers who will be out of the area, such as preparing money to pay retribution and admission ticket. (3) The queue theory analysis is easier to use to analyze the queue at the counter than the shock wave analysis. Shockwave analysis is more macro when using traffic parameters such as volume, speed of density and capacity of the road wherein the change of traffic flow due to the obstacle becomes a reference to analyze the shock waves. In the case of the exit gateway of the vehicle counter Megamas, the length of the road for queuing is very limited, and if the number of vehicle queue is too long until the intersection between segment A and segment B then speed in both segments will be affected due to queue. Eventually, queuing theory in analyzing the queue at vehicle counter in Megamas area is more effective and efficient to use. Keywords : shockwave, queue theory, queue length

Abstract

Penelitian dilakukan pada 6 simpang bersinyal, yaitu persimpangan Jalan Yos Sudarso-Jalan Maesa, Jalan B.W Lapian-Jalan Jenderal Sudirman, Jalan Yos Sudarso-Jalan Jenderal R.E Martadinata, Jalan R.E Martadinata-Jalan R.E Martadinata IV, Jalan Diponegoro-Jalan Lumimuut-Jalan Toar Jalan 14 Februari, Jalan Babe Palar-Jalan Maengket-Jalan 17 Agustus. Penelitian ini bertujuan untuk mencari nilai ekivalensi mobil penumpang (emp) dari beberapa jenis kendaraan yang ada di kota Manado. Masing-masing kendaraan memiliki karakteristik pergerakan berbeda-beda sehingga perlu dikonversikan satu terhadap lainnya agar pengaruh setiap kendaraan terhadap lalu lintas keseluruhan dapat diketahui. Mobil penumpang diambil sebagai kendaraan acuan, sementara jenis kendaraan lainnya diekivalensikan. Survei dilakukan pada jam-jam puncak dengan kondisi arus lalu lintas jenuh (saturation flow). Data Sampel diperoleh dengan cara perekaman melalui kamera video (handy cam) dan dianalisa, sehingga diperoleh data jumlah kendaraan yang berbeda-beda per periode pelepasan (saat lampu hijau) yang sama. Sampel harus diseleksi karena tidak semua kondisi lalu lintas jenuh dapat dipakai sebagai bahan analisa. Sampel yang memenuhi syarat dianalisa dengan metode statistik regresi berganda untuk mendapatkan koefisien persamaan yang merupakan nilai ekivalensi mobil penumpang untuk tiap tipe kendaraan. Selanjutnya, nilai emp akhir tiap jenis kendaraan didapat dengan merata-ratakan nilai ekivalensi mobil penumpang dari tiap lengan simpang yang ditinjau.Hasil penelitian menunjukkan bahwa nilai ekivalensi mobil penumpang (emp) untuk kendaraan ringan/ LV (Light vehicle) = 1,00, Simpang Jalan Yos Sudarso-Jalan Maesa kendaraan berat (HV) = 3,1; sepeda motor (MC) = 0,4; Simpang Jalan B.W Lapian-Jalan Jenderal Sudirman kendaraan berat (HV) = 1,6; sepeda motor (MC) = 0,6; Simpang Jalan Yos Sudarso-Jalan Jenderal R.E Martadinata kendaraan berat (HV) = 2,3; sepeda motor (MC) = 0,4; Simpang Jalan R.E Martadinata-Jalan R.E Martadinata IV kendaraan berat (HV) = 0,9; sepeda motor (MC) = 0,3; Simpang Jalan Diponegoro-Jalan Lumimuut-Jalan Toar-Jalan 14 Februari kendaraan berat (HV) = 1,5; sepeda motor (MC) = 0,7; Simpang Jalan Babe Palar-Jalan Maengket-Jalan 17 Agustus kendaraan berat (HV) = 1,2; sepeda motor (MC) = 0,5.Nilai ekivalensi mobil penumpang (emp) di kota Manado diambil dari nilai rata-rata ekivalensi mobil penumpang (emp) enam simpang bersinyal sehingga diperoleh kendaraan berat (HV) = 1,7 dan sepeda motor (MC) = 0,4. Hal ini menunjukkan bahwa nilai ekivalensi mobil penumpang (emp)  yang diberikan oleh MKJI 1997 (HV=1,3; MC=0,4) sudah tidak layak digunakan pada persimpangan di kota Manado karena nilai ekivalensi mobil penumpang (emp) tersebut berbeda dengan hasil perhitungan. Hasil ini dapat dijadikan dasar dalam perhitungan berbagai karakteristik lalu lintas di kota Manado. Kata kunci : Ekivalensi mobil penumpang (emp), simpang bersinyal, lalu lintas, jam puncak

Abstract

Lingkungan Lima Kelurahan Wawalintouan Kecamatan Tondano Barat Kabupaten Minahasa adalah daerah yang sering mengalami genangan pada saat musim penghujan. Genangan tersebut mengakibatkan terganggunya aktifitas masyarakat sekitar dan masyarakat pengguna jalan. Hal ini dikarenakan sebagian daerah tersebut belum memiliki saluran dan gorong-gorong. Untuk itu dilakukan pengembangan sistem drainase, yang direncanakan agar memberikan solusi penanganan genangan yang terjadi Analisis hidrologi dilakukan untuk mendapatkan debit rencana (Qrenc). Perkiraan hujan rencana dilakukan dengan analisa frekuensi terhadap data curah hujan dengan kala ulang 10 tahun menggunakan metode log Pearson III dan perhitungan intensitas hujan menggunakan rumus Mononobe. Debit rencana dihitung menggunakan metode rasional. Untuk menghitung debit kapasitas (Qkaps) dari saluran dan gorong-gorong, dilakukan analisis hidrolika. Dari perbandingan antara debit rencana dan debit kapasitas (Qrenc ≤ Qkaps), diketahui kemampuan dari setiap saluran dan gorong-gorong dalam menampung debit rencana. Berdasarkan hasil analisis di lokasi tersebut perlu dilakukan perbaikan agar saluran mampu menampung debit yang ada, diantaranya dilakukan perubahan dimensi 6 ruas saluran dari 20 ruas saluran eksisting serta penambahan 16 ruas saluran baru dan 6 gorong-gorong baru. Kata Kunci : Genangan, Debit rencana, Debit kapasitas, Sistem drainase
