Abstract

The mode choice of public transport could be the most important stage in transportation planning. Because of its key role in many transportation policies. Passenger mode choice behaviour based on the mode characteristics and level of service, as well as user characteristics. It is necessary to figure out the preference of mode choice between train and bus route of Cepu-Semarang economic class. This recearch aims to develop mode choice model and analyse sensitivity of the mode choice of public transport. The approach used in this research is stated preference technique. Independent variables are the difference value of : travel cost, travel time, and acces time between train and bus. Data analysis on model is carried out using binomial logit model, and estimation of model parameter is carried out using multiple regression analysis. Results of descriptive analysis showed that majority of respondents option is “definitely train”. It is also shown that train was given preference over bus. According to statistics test, travel cost attribute is excluded from analysis due to its colinearity. Mode choice model obtained from analysis is : Pilihan = 1,045-2,011*∆Travel Time-0,023*∆Acces Time, and probability model of mode choice is : . Based on the direct and cross elasticity, the travel time attribute has bigger elasticity value than acces time.Travel time is more sensitive than acces time in choice probability of train and bus.

Abstract

Infrastruktur perekonomian dibutuhkan untuk meningkatkan produktivitas, memperlancar proses distribusi barang dan jasa serta meningkatkan efektivitas dan efisiensi operasional dunia usaha. Infrastruktur perekomian juga mempunyai peranan yang sangat penting dalam menggairahkan iklim dan perkembangan investasi di daerah. Untuk itulah pemerintah daerah perlu memberikan perhatian dalam penyediaan infrastruktur di daerahnya, agar perekonomian daerah dapat bertumbuh dan berkembang dengan baik. Keterkaitan antara infrastruktur dengan pertumbuhan ekonomi masyarakat perlu diketahui bagi stakeholder terkait untuk kepentingan evaluasi dan pembangunan infrastruktur sejak dari penyusunan anggaran, perencanaan, pelaksanaan, dan perawatan infrastruktur. Sehingga diharapkan pembangunan infrastruktur akan tepat sasaran dan mampu memberikan kapasitas layanan yang sesuai dengan potensi daerah yang akhirnya bermuara kepada peningkatan pertumbuhan ekonomi masyarakat. Oleh karena itu, penelitian tentang keterkaitan infrastruktur dan pertumbuhan ekonomi perlu dilakukan. Penelitian bertujuan menganalisis keterkaitan hubungan antara infrastruktur dengan Produk Domestik Regional Bruto (PDRB). Variabel dependen dalam penelitian ini adalah PDRB Atas Dasar Harga Konstan (ADHK). Sedangkan variabel independen adalah : luas lahan teririgasi, panjang jalan dan jembatan, daya listrik tersambung, dan jumlah air bersih tersalur. Metode untuk menganalisis keterkaitan infrastruktur dengan PDRB Kabupaten Blora adalah dengan analisis data time series dan analisis data panel, yaitu data gabungan time series dan cross section. Hasil analisis menunjukkan infrastruktur jalan kabupaten merupakan infrastruktur yang paling signifikan menjelaskan hubungan peningkatan PDRB dengan jenis infrastruktur di Kabupaten Blora, dengan bentuk persamaan matematika : PDRB = 3,368 + 0,013*PANJANG JALAN KABUPATEN. Interpretasi persamaan model di atas adalah : setiap pertambahan panjang jalan kabupaten sebesar 1 km, maka akan menaikkan PDRB sebesar 0,013%.

Abstract

Industrial waste pollution from the upstream of the Bengawan Solo river, makes the river's quality unfit for various purposes. Water filtering needs to be done first to improve its quality. One of them is the absorption process. One of the adsorbents that have good prospects is rice husk waste because of its ability to bind the adsorbate components. Study related to the effectiveness of rice husk charcoal as a water filter material need to be carried out before it can be used as a water filter material. Making appropriate filter technology needs to be done to apply it. The results of the analysis show that the filter can improve the physical parameters of water, namely reducing the residue by 25% on average. Meanwhile, from inorganic chemical parameters, only DO (Dissolved Oxygen) elements have decreased in quality standards. The organic chemical parameters, namely the phenol content are relatively constant, this indicates that rice husk charcoal is not effective in binding phenols. Based on Government Regulation No. 82 of 2001, the filtered water is classified as Class I. However, in its use, other parameters that have not been studied should be studied, namely microbiology, other organic chemistry, radioactivity, etc.The technological capacity needs to be increased by the use of a larger body and or a reduction in the thickness of the filter layer. Meanwhile, the manufacture of rice husk charcoal should use controlled combustion mechanisms and or husk charcoal activation with the chemical Na OH to strengthen the properties of the husk charcoal adsorbent against harmful chemical compounds.

Abstract

The current land use have made the corridor of Jalan GOR in Blora Regency plays an important role in the aspect of transport demand. The area’s development must be balanced with the adequate transport supply in such a way that it will minimize the negative impact due to the imbalance between demand and transport supply. One of the existing transport supply is an unsignalized intersection at the eastern end of the corridor. The potential problem due to the existence of nearby land uses, such as gas stations, on intersection performance is : the presence of delays. Based on those research backgrounds, the formulation of the research problem is: how does the existence of gas station affect the intersection performance and the cost of delay? This research aims to analyze the performance of intersections due to the existence of gas stations. The results of the analysis show that the existence of gas station gives various contribution to intersection performance parameters. Respectively, the biggest effect occurred on the increase in vehicle volume, degree of saturation, and total delay (especially traffic delay). Overall, the existence of a gas station has no effect on the level of service’s value of the intersection. Meanwhile, the value of the highest delay costs occurs during the peak hours of the day. The predicted intersection performance without any geometric improvement for 5 years will begin to decline in third year. Meanwhile, if the intersection is widened, it will begin to decline in the fourth year. However, this geometric improvement has only a very small effect on intersection performance.

Abstract

The existence of schools on Gatot Subroto Street has potential impact to generate a number of trips. The area’s development must be balanced with the provision of adequate transportation. The first step that needs to be taken is to provide information regarding the characteristics of the attraction and distribution patterns of trips to the area in such a way that the demand for transportation can be anticipated. Therefore, the formulation of the research problem is: what are the characteristics of the attraction and the pattern of distribution of trips to the educational area of ​​Gatot Subroto Street, Blora Regency? While the purpose of the research is to analyze the attraction of trips and distribution patterns of trips to the area. Secondary data was obtained from the school and the Blora District Education Office, namely: teacher and employee population, student population, mode used, land area, building floor area, and parking area. Primary data was obtained from an interview survey via google form. The dependent variable is the number of trips and the independent variables: number of students, teachers & employees, land area, floor area, parking area. Based on the results of the analysis, trips attraction is strongly influenced by the population of travelers. The second variable that has a statistically significant effect is the size of the parking area. Most trips to this area have a range of 3-6 km. While the trip barrier function that best describes the trip distribution is the exponential function. The limitation of this research is that it is not yet known how the impact of Covid-19 has on travel attraction. The research results can be used as a basis for further research, namely the calibration of the transportation demand model. Zoning also needs to use village-based travel origin zones to obtain more accurate analysis results

Abstract

The Bojonegoro-Ngawi highway KM.33-KM.63 is part of the national road that connects the provinces of East Java and Central Java. One of the strategic roles of this road segment is that it is the closest access to the Trans Java toll road Solo-Kertosono section. Accidents on these roads have the potential to result in a decrease in the performance of these roads, namely in the aspect of road user safety. Therefore, it is necessary to conduct a study of accident-prone areas on this road section. Accident data available at the time the research was conducted was still in the form of tabulation of raw accident data. Information regarding accident-prone locations and costs is not yet available. This information is needed in an effort to improve traffic safety for the prevention and handling of accidents. Based on the background of the problem, the formulation of the research problem is: where are the accident-prone locations and what are the costs incurred? Analysis of accident-prone locations uses the Equivalent Accident Number (EAN) and Upper Control Limit (UCL) methods and the accident cost analysis method uses the Gross Output method. The results of the analysis of accident-prone locations show that there are 12 segments whose AEK values ​​are above the limit value or UCL. The biggest loss in an accident is caused by the death toll. While the largest accident classification costs occur in fatal accidents. Meanwhile, the analysis of accident costs per road segment based on the type of accident victim shows that the top 3 segments with the highest accident costs are identical to the results of the analysis of AEK and UCL values. The limitation of this research is that it has not considered qualitative losses. This method does not include compensation for pain, fear, grief or suffering. Therefore, for further research it is necessary to carry out a more comprehensive analysis regarding the types of material and non-material losses

Abstract

Determining the priority order for road repairs requires a road damage study to take a complete inventory of road conditions by means of a survey to collect data on pavement conditions. Determining the level of damage and analyzing the economic feasibility of handling road damage based on the survey results is useful for determining the priority order for handling which parts of the road need to be repaired first. Based on the description of the background to the problem, the formulation of the research problem is: how to determine the priority for handling road damage based on the level of road damage and the economic value resulting from repairing the damage? Primary data collection was carried out by surveying road damage using the survey instrument method of Dirgolaksono and Mochtar (1990). Data analysis is divided into 3 parts: road damage analysis, economic analysis using the ND Lea Consultant method, and determining priorities for handling road damage. The results of the identification and analysis of the level of damage per 100 m of road length showed that Jl. Gatot Subroto segment B (west to east traffic direction) has a greater value than the opposite direction. Meanwhile, the BCR, NPV and LHR values ​​for segment A have greater values ​​than segment B. Therefore, the priority for handling road damage is prioritized on segment A first. This research has several limitations related to several assumptions used. The Consumer Price Index (CPI) data used is assumed to be the same as the Kudus Regency CPI due to limited secondary data. In addition, it is necessary to carry out a comparative analysis of the BOK results if a different type of road damage management is used to that used in this research. Likewise, analysis needs to be carried out regarding determining priorities for handling damage per road length/section/road stationing. Method development or improvement needs to be carried out for further research in order to overcome the subjectivity of observations. For example: by using a scoring or weighting method for parameters that influence priority determination by conducting interview surveys with experts or stakeholders related to road construction.

Abstract

One of the causes of road damage is the presence of excess water due to inadequate drainage systems. Initial information related to the condition of existing drainage and also the damage to existing roads and the relationship between the two is needed for maintenance, evaluation, planning, and construction of both infrastructures so that the priority scale of handling can be applied for budget efficiency and effectiveness. Based on the problems above, this study was conducted with the aim of evaluating the condition of the road and its drainage. Data collection was carried out using survey and field observation methods. Analysis of pavement conditions using the Pavement Condition Index (PCI) method. Analysis of drainage conditions using a qualitative descriptive method with drainage performance benchmarks based on the Bina Marga Road Surface Drainage Design Guidelines (1990). The road sections that were the objects of the study were: Jalan Sorogo, Jalan Gajahmada, and Jalan Hayamwuruk in Cepu District. The characteristics of the road surface drainage surveyed were: road transverse slope, side channel dimensions, and channel sedimentation. The results of the analysis showed that the average road condition at the time of the study had a moderate level of damage with a PCI value of 46 while the drainage had a moderate level of damage both functionally and structurally. The drainage conditions that most affect the road are channel dimensions that are not in accordance with standards and changes in function from open to closed channels. While the most dominant effects of surface drainage conditions are: puddles and water infiltration. With the most dominant types of road damage due to puddles and infiltration are: crocodile skin cracks, peeling of the surface layer, and holes
