Abstract

Transportation is defined as the activity of moving passengers and goods from one place to another, in which there is an element of movement. Transportation plays an important role in the development and development of infrastructure in urban areas. This is the main reason for choosing those that are considered efficient in terms of fuel in meeting the transportation needs of the vehicles used. According to the author's observations, people tend to prefer to buy subsidized fuel because of the higher prices. cheap, so willing to wait in long lines and cause the road to be consumed by queues that disturb other road users. Fuel oil itself is divided into 2 groups, namely subsidized and non-subsidized. The problem of adjusting subsidized fuel prices has also developed a discourse regarding who is entitled to subsidized fuel based on Presidential Regulation Number 43 of 2014 as amended by Presidential Regulation Number 43 of 2018 concerning the supply, distribution, and retail selling price of BBM. Data collection was carried out directly in the field by giving questionnaires and asking directly to Bandar Lampung City Government Employees. After that, perform an analytical test by evaluating the tariff according to the ability to buy Ability To Pay (ATP) and the willingness of consumers to buy Willingness To Pay (WTP) using the Analytical Hierarchy Process (AHP) method. From this, the authors are interested in conducting research with the title: "SUBSIDIED AND NON-SUBSIDIED OIL FUEL PREFERENCES IN BANDAR LAMPUNG GOVERNMENT EMPLOYEES".This research begins by collecting literature studies and data, including primary and secondary data. Primary data were obtained through interviews with several respondents using the selected random sampling method. Secondary data sourced from BPS, PT. Pertamina, Bandar Lampung City Government and the results of other studies related to this topic. The data will be used for the next process, namely the analysis of calculations, and the last stage, namely the results and drawing conclusions.Based on the results of the study using the Analytical Hierarchy Process method, it can be concluded that risk is the most influential criterion in selecting the type of fuel oil.Keywords: preferences, subsided and nonsubsided oil fuel

Abstract

Abstract One method of road infarstructure maintenance is dredging the old asphalt pavement to then be re-coated with a new asphalt pavement. The result of dredging old asphalt pavement is called RAP (Reclaimed Asphalt Pavement). RAP can be used as an aggregate substitution in the manufacture of new asphalt pavement layers, especially in the AC-WC (Asphalt Concrete-Wearing Course) layer by recycling. In addition to the utilization of RAP, improving the quality of road pavement also needs to be done by modifying paved mixtures by adding additives to the asphalt. The additive added in this study is ATK (Coconut Shell Charcoal). This study aims to determine the effect of the addition of ATK on the durability of RAP-based AC-WC mixtures. Furthermore, the immersion of the test object is carried out with a variation of 30 minutes, 1 day at a temperature of 60 °C. The effect of the addition of ATK to the RAP-based AC-WC mixture on its durability judging from the residual Strength Index (IKS) value shows that the residual strength value is getting smaller along with the increasing rap levels and ATK levels in the mixture, this can be caused because ATK is an organic material that is susceptible to the influence of water and RAP is a used asphalt pavement that has suffered damage due to road service. Keywords: AC-WC, RAP, Durability,Coconut shell charcoal Abstrak Salah satu metode pemeliharaan insfrastruktur jalan adalah pengerukan perkerasan aspal lama pada jalan untuk kemudian dilapis kembali dengan perkerasan aspal baru. Hasil dari pengerukan perkerasan aspal lama disebut dengan RAP (Reclaimed Asphalt Pavement). RAP dapat dimanfaatkan sebagai substitusi agregat pada pembuatan lapis perkerasan aspal baru khususnya pada lapisan AC-WC (Asphalt Concrete-Wearing Course) dengan cara daur ulang. Selain pemanfaatan RAP, peningkatkan kualitas dari perkerasan jalan juga perlu dilakukan dengan cara memodifikasi campuran beraspal dengan menambahkan bahan aditif pada aspal. Bahan aditif yang ditambahkan dalam penelitian ini yaitu ATK (Arang Tempurung Kelapa). Penelitian ini bertujuan untuk mengetahui pengaruh penambahan ATK terhadap durabilitas campuran AC-WC berbasis RAP. Selanjutnya perendaman benda uji dilakukan dengan variasi 30 menit, 1 hari pada suhu 60˚C. Pengaruh penambahan ATK pada campuran AC-WC berbasis RAP terhadap durabilitasnya ditinjau dari nilai Indeks Kekuatan Sisa (IKS) menunjukkan nilai kekuatan sisa yang semakin kecil seiring dengan bertambahnya kadar RAP dan kadar ATK dalam campuran, hal ini dapat disebabkan karena ATK adalah bahan organik yang rentan terhadap pengaruh air dan RAP adalah perkerasan aspal bekas yang telah mengalami kerusakan akibat masa layan jalan. Kata Kunci: AC-WC, RAP, Durabilitas, ATK

Abstract

The Covid-19 virus has caused a decrease in transportation movement activities on the Z.A Pagar Alam road. Transportation movement activities due to the pandemic in which the government established a WFH (Work From Home) with this policy resulted in a reduction in the level of transportation modes so that it had a positive effect, namely reducing traffic congestion in the city center and also reducing air pollutants.In connection with the above problems, it is necessary to study the calculation of the emission load on the Z.A Pagar Alam road during the new normal period which can then be compared with the Z.A Pagar Alam emission load during the normal period, in order to find out how much the emission load changes on the R.A road. Kartini due to Covid-19.this study aims to determine the emission load of Pagar Alam Z.A during new normal conditions and during normal conditions. The results of this study indicate that there is a change in the emission load for each of the existing concentrates and the most significant is CO2 on the Z.A Pagar Alam road due to changes in vehicle volume that occur during normal and new normal conditions.

Abstract

Self compacting concrete (SCC) is a concrete innovation that is carried out to overcome problems during casting that does not require manual compaction even in hard-to-reach places such as tight reinforcement. In this study, 3D Dramix steel fibers and bendrat wire were used as a mixture in SCC with volume fractions of 0%, 0.5%, 1%, 1.5%. The addition of this fiber aims to determine the effect of the two fibers on SCC on compressive strength, split tensile strength and flexural tensile strength. The sample in this study was a cylinder with a diameter of 150 mm and a height of 300 mm for testing the compressive strength and split tensile strength while the flexural tensile strength used a beam sample with a size of 100x100x400 mm. All samples of these specimens were tested when the concrete was 28 days old. The increase in the value of compressive strength, split tensile strength and flexural strength at the addition of 1.5% steel fiber were 26.39%, 64.71% and 111.88% respectively for concrete with 0% fiber. While the increase in compressive strength, split tensile strength and flexural strength with the addition of 1.5% bendrat wire was 20.31%, 60.74% and 76.18% for concrete with 0% fiber, respectively.

Abstract

Self Compacting Concrete (SCC) is an innovation of concrete which has an ability to flow on its own to fill the empty voids between reinforcement and formwork without support of compaction equipment to obtain its optimum compaction. In this research, concrete cylinder with dimension of 15 cm for diameter and 30 cm for height were used as a specimen and mixed with fly ash type C as cement partial substitute material and additional substance by variation of 0%, 3%, 6%, 9%, and 12% with water cement ratio of 0.41. Slump flow test was perform to identify concrete flowability and workability followed by concrete compression test to identify compressive strength which was conducted at the age of 35 days and 56 days. Due to the fact that percentage variation of fly ash increment, the value of slump flow test was experiencing degradation whereas the compressive strength was increased. Nonetheless, the optimum fly ash application appeared when fly ash was applied as a cement partial substitute at variation of 3%, which provide concrete compressive strength in the amount of 35.98 MPa (35 days) and 33.68 MPa (56 days), and the value of concrete density were 2313.21 kg/m3 and 2279.66 kg/m3 , where the standard of slump flow test and T50 values had accomplished.
