Shopping centres in Denpasar are faced with parking supply problems. One of the problems is the difficulty in providing sufficient parking spaces based on actual demand. Efficiency of parking supply can be achieved if parking supply meets actual demand. This research is conducted in order to know parking characteristic, the degree of relation ship between parking demand and parameters of shopping centres as independent variables, to develop parking demand model and to analyse parking demand standard for shopping centres in Denpasar. Primary and secondary data are required in order to know parking characteristics. Primary data were obtained from direct observation onsite which include: parking vehicles data, number of visitor & parking inventory. Primary data were obtained from one day survey an Saturday between 09.00 am to 09.30 pm at each shopping centres. Secondary data (i.e. parameters of shopping centres) were obtained from the management of shopping centres. Shopping centres included in this study are: Robinson, Alfa Imam Bonjol, Ramayana Bali Mall, Tiara Grosir, Alfa Diponegoro and Hardy’s Sesetan. Parking demand models were developed by using simple & multiple regression methods with the help of SPSS 15.0 software. Independent variables included in this study are: floor area, netto floor area, service floor area, number of permanent employees, number of non-permanent employees, number of cashier and number of visitors. The dependent variables are average parking accumulation for car, motor cycle and taxi. Parking demand standards were calculated based on regression analysis of parking demand and shopping centres parameters. The results of the simple regression analysis showed that the relationship between car parking demand and number of non-permanent employees (X5) was indicated by regression formula : Y1 = -1,805 + 0,358.X5 (R2 = 0,965), where the car parking demand standard was 1,097 spaces/person. The relationship between motor cycles parking demand and number of non-permanent employees (X5) was indicated by regression formula: Y2 = -24,497 + 2,059.X5 (R2 = 0,873), where the motor cycles parking demand standard was 6,205 spaces / person. The relationship between taxi parking demand and number of non-permanent employees (X5) was indicated by regression formula: Y3 = -1,262 + 0,037.X5 (R2 = 0,915), where the taxi parking demand standard was 0,001 spaces / person. The results of the multiple regression analysis showed that the relationship between car parking demand and number of non-permanent employees (X5) was indicated by regression formula : Y1 = -1,805 + 0,358.X5 (R2 = 0,965). The relationship between motor cycles parking demand and combination number of permanent employees (X4) with number of non-permanent employees (X5) was indicated by regression formula : Y2 = 135,401 – 1,200.X4 + 2,829 (R2 = 0,972). The relationship between taxi parking demand and number of non-permanent employees (X5) was indicated by regression formula: Y3 = -1,262 + 0,037.X5 (R2 = 0,915).

FINANCIAL ANALYSIS OF BALI-EAST JAVA TIRTAYATRA TRANSPORTATION ABSTRACT Bali, with its predominantly Hindu, has experienced a fairly rapid development of the tourism sector. With personal awareness and supported by the better economic condition, the Balinese Hindu people are able to religious travel (tirtayatra) to other areas. Travel Companies catch this opportunity by opening travel packages to several temples in East Java. This study aims to analyze the level of financial investment feasibility in the tirtayatra transportation business. Feasibility of investment can be obtained by comparing the variables of benefit and cost. Analysis of the level of feasibility is determined by applying the NPV, IRR and BCR methods and sensitivity analysis. Data used, both primary and secondary, are obtained from several Travel Companies in Bali. From the results it can be concluded that the investment of the Tirtayatra package Bali - East Java is a package that continues to grow. In the feasibility analysis that is served by 3 medium bus and the vehicles economic life of 7-year, the Present Value of benefit is Rp. 11,891,301,439 and the Present Value of cost is Rp. 11,335,305,821. Therefore, the result gives the value of NPV Rp.555,995,618 > 0, BCR = 1.0490 > 1 and IRR = 27.63% > i (17%). Thus the investment at religious travel can be considered feasible. However, this package will be inappropriate if the annual interest rate passes the value of 27.63%.

Abstract: Celukan Bawang Harbour is located in the northern province of Bali. Port traffic through the Celukan Bawang Harbour during the period of 2005-2009 has decreased. So It is necessary for the performance evaluation of the port so that the reduction in traffic flows of goods can be determined. In addition, this study also predict traffic flow of goods 30 years future so it can be evaluated development of the port in the future . The evaluation was done based on the performance data Celukan Bawang Harbour last 10 years. Then a prediction of traffic flows to goods the next 30 years using multiple linear regression analysis. For the evaluation of the development of the port to analyze the financial feasibility of the port master development plan (RPIP) 10 years from 2014 to 2023 years that compare to the development plan based on a prediction of traffic flows. Based on the evaluation of operating performance, port obtained poor performance. This is evident from the performance indicators in 2013 that the waiting time: 58 hours and BOR value: 88 % above the standard value is specified, while the percentage of effective time / Berthing time: 31.6%, SOR: 6%, Yor: 0% is far below the standard set value. Meanwhile, if the predicted assuming port performance has been improved, the traffic flow of goods grew 10.90% annually. Financial analysis based RPIP port development is not feasible to get the value NPV = -1,521,941,710 BCR value = 0.9828 and a IRR = 11.46%, while the development of port based traffic flow prediction goods with the sensitivity condition cost increase 15% and benefits decrease 15% get decent results with NPV = 12,191,952,255 and BCR value = 1.4546.

Nusa Penida (20,284 ha) is nearly 2x the areas of the other three districts of Klungkung regency,which located in the Bali mainland (11,216 ha). However, the condition of people is very underdeveloped. The regionsdisparityis caused by various factor, one of them is "isolated" area of ??Nusa Penida. So,itsneed to be planned a pioneering road to improve accessibility. In the prediction of traffic assignment, of course, can not be based solely on the existing very small trip generation. For that ananalogous method should be set up to the region that has the same characteristics. Analogy method was developed through a comparative study to other areas of Bali with a similar limestone structure, the same road networkand tourist areas. In accordance with development plan, it can be predicted that the road ADT in 2020 will be 5,800.62 pcu/day and DHV725.08 pcu/hour. Meanwhile, the end of the road horizon-year 2045 reaches 37,576.31 pcu/day with DHV of 4,697.05 pcu/hour. Assuming that of the rural environment, the capacity of the 2/2UD hilly road is 2,910 pcu/hour. Therefore, from the loading analysis shows that in the year of 2038 the road should be widened to be 4 lanes to serve the-2traffic directions. Keywords:pioneer road, analogy method, nusa penida

ABSTRAK Berdasarkan hasil survai tahun 2014, kecepatan perjalanan rata-rata segmen terkrusial di jalan utama Ibu Kota Kecamatan (IKK) Nusa Penida hanya 23,61 km/jam akibat tingginya intensitas parkir di tepi jalan serta belum tersedia rute alternatif. Pemerintah Kabupaten Klungkung telah merencanakan tata guna lahan (TGL) di IKK Nusa Penida dengan membuat Rencana Detail Tata Ruang (RDTR) dan jalan lingkar untuk memindahkan lalu lintas menerus. Jalan lingkar serta TGL yang direncanakan dalam RDTR diasumsikan beroperasi tahun 2020. Penelitian ini menganalisis beban lalu lintas total pada jalan lingkar yang terdiri dari volume lalu lintas yang dihasilkan TGL dan volume lalu lintas menerus sehingga jumlah lajur (kapasitas jalan) cukup agar tingkat pelayanan jalan tidak kurang dari level C sampai akhir umur rencana jalan tahun 2040. Data yang digunakan berupa tingkat bangkitan perjalanan dari tiap tipe TGL, data pencacahan lalu lintas, waktu tempuh kendaraan dan asal-tujuan perjalanan. Data survai diperoleh tahun 2018. Volume lalu lintas yang membebani jalan lingkar IKK Nusa Penida pada jam puncak tahun 2020 terdiri atas; 1) volume lalu lintas menerus hasil persamaan Moskowitz untuk jarak dan waktu yang dihemat sebesar 207,11 smp/jam; 2) bangkitan lalu lintas dari TGL (lalu lintas lokal) sebesar 346,56 smp/jam, sehingga total beban lalu lintas adalah 553,67 smp/jam. Total beban lalu lintas bervariasi bergantung pada tingkat pertumbuhan yang dipilih. Berdasarkan tingkat pertumbuhan rendah jumlah lajur 2/2 UD cukup sampai dengan akhir umur rencana, namun untuk pertumbuhan sedang dan tinggi diperlukan 4/2 D mulai tahun 2035.

ABSTRACT: In developed countries, road capacity values derived from time headway is in accordance to their local traffic characteristics. In theory, time headway standards are developed using statistics models. These standards however, are not necessarily relevant to use in Indonesia. This is because of the differences in traffic conditions and motorists behaviours between those in developed countries and Indonesia. This study is to develop the time headway distribution model and subsequently to determine lionk-road capacity in the city of Denpasar, Bali Province. The study consists of time headway data analysis, model calibration and validation and road capacity values??determination. The study found that normal distribution model fitted the local traffic conditions. Road capacity values are of 2,466 pcus/hour and 2,900 pcus/hour obtained from time headway model and the Indonesian Road Capacity Manual (MKJI) respectively.

One of asphalt mixture being developed is Cold Bituminous Emulsion Mixtures (CBEMs) that its performances need to be improved. Within this experiment it is done by adding epoxy. The objective of this study was to analyze the characteristic of CBEMs with and without epoxy. Epoxy variation was 1%, 3%, and 6% by weight of residual bitumen. The epoxy was mix with hardener in ratio 1:3, then mixed with bituminous emulsion. Epoxy was added into the Optimum Residual Bitumen Content (ORBC) of 7,5%. The aggregate was dampened with water first then mixed with emulsion that had been added with epoxy, then compacted. It was found that CBEMs added with 1% and 3% epoxy met the specifications, however CBEMs with 6% of epoxy did not, because the porosity was 17,83% (spec.5%-10%). The soaked stability of the mixture without and with epoxy 3% was 1177,02 kg and 1416,47 kg. Addition of 3% epoxy increase soaked stability up to 20%. In stiffness, creep, and fatigue tests, CBEMs without epoxy compared by CBEMs with 3% of epoxy, respectively gave result: stiffness 1854 MPa: 959 MPa (-48,27%); strain at 106 loads repetition (Nf) was 78,09 µ?: 93,22 µ? (+19,38%); Nf at strain 100 µ? was 358.897 times: 539.585 times (+50,35%); creep slope was 23,752: 39,939 (sample was collapsed before 3600 loads repetition). However, epoxy caused the mix stiffer hence increase the porosity of the mixture to 20%. It is suggested to reduce the hardener content of the epoxy, to manitain workability and reduce porosity.

ABSTRAK Jalan Imam Bonjol Denpasar yang termasuk dalam ruas jalan nasional Denpasar – Tuban merupakan salah satu jalan arteri primer yang memiliki peranan penting dan padat lalu lintas. Pesatnya perkembangan tata guna lahan di sekitar jalan ini serta tingginya volume lalu-lintas yang melewati ruas jalan ini berakibat pada menurunnya tingkat pelayanan jalan sehingga sering menimbulkan kemacetan. Sebagai solusi dari masalah tersebut, pemerintah merencanakan peningkatan kapasitas jalan melalui pelebaran jalan Imam Bonjol, dengan menutup permukaan Tukad Teba menggunakan box culvert. Penelitian ini dilakukan untuk menganalisis kinerja jalan Imam Bonjol Denpasar tanpa dan dengan adanya pelebaran jalan. Data yang digunakan untuk analisis kinerja jalan adalah berupa data sekunder yang diperoleh dari instansi terkait. Hasil analisis menunjukkan bahwa kinerja jalan Imam Bonjol kondisi eksisting (tahun 2019) tanpa adanya pelebaran mencapai derajat kejenuhan sebesar 1,61-2,14, dengan tingkat pelayanan F pada setiap segmen. Kinerja jalan Imam Bonjol pada tahun 2019 apabila rencana pelebaran dilakukan mengakibatkan perubahan derajat kejenuhan menjadi 0,41 s.d 1,00, dengan tingkat pelayanan jalan menjadi bervariasi antara B s.d E.

AbstrakCold Paving Hot Mix Asbuton (CPHMA) adalah campuran yang terdiri dari agregat, asbuton butir, bahan peremaja dan bahan tambah lain yang dicampur panas dipadatkan dingin (pada temperatur ruang 30°C). Karakteristik campuran dipengaruhi temperatur pemadatan. Tujuan penelitian ini adalah untuk memperoleh: kadar aspal residu optimum, temperatur pemadatan ideal dan perbandingan karakteristik CPHMA yang dipadatkan secara dingin dan panas. Pemadatan dilakukan pada suhu 30°C, 60°C, 90°C, 120°C, dan 150°C. Diperoleh hasil, kadar aspal residu optimum 7 %; suhu pemadatan ideal 90°C. Pemadatan dibawah suhu 90°C memberikan porositas lebih tinggi berkisar antara (4,86-5,53)% namun masih memenuhi spesifikasi (4-10%). Pemadatan diatas suhu 90°C memberikan porositas antara (2,04-3.0)%, yang lebih rendah dari spesifikasi. CPHMA yang dipadatkan pada suhu ideal 90°C memberikan karakteristik Marshall, cantabro, kekakuan (stiffness), rangkak (creep), dan kelelahan (fatigue) lebih baik dibandingkan dengan CPHMA yang dipadatkan dingin.AbstractCold Paving Hot Mix Asbuton (CPHMA) is a mixture that consists of aggregates, asbuton particles, rejuvenating materials and other added materials, which were hot mixed and compacted cold (at ambient temperature 30°C). The characteristics of the mixture were affected by compaction temperatures. The objectives of this study were to obtain: residual optimum asphalt content; ideal compaction temperature and characteristics comparison of CPHMA compacted cold and hot. Compaction were carried out at 30°C, 60°C, 90°C, 120°C and 150°C. It was obtained that the optimum residual asphalt content for CPHMA mixture was 7% and the ideal compaction temperature was 90°C. Compaction at temperature lower than 90°C gave higher porosity, i.e between (4.86-5.53)%, nonetheless still met specification (4-10)%. Compaction at higher than 90°C gave porosity between (2.04-3.0)% which were lower than the specification. CPHMA compacted at ideal 90°C gave better Marshall characteristics, cantabro, stiffness, creep, and fatigue, compared to the cold compacted CPHMA.

Southern Bali, a tourism center of Indonesia, has been rapidly developed. Unfortunately, the development is not followed simultaneously by the development of adequate transportation network, as a result, traffic congestion are inevitably occurred along every urban road in the district. Therefore integrated development and regional transport planning therefore, is urgently required. In this study, trip generation is determined using Category Analysis. It is Figured out from the household based interview that Denpasar Barat zones are found to have the largest trip generation while Pecatu zones are found to be the smallest. Most of the household trips generated use private vehicles (94.95%) and the rest uses public transport. This also indicates that public transport services in Southern Bali still need to be developed.
