Abstract

Watershed management is starting with knowing and recording the problems that exist in the watershed. Condition of the watershed that continues to deteriorate can trigger natural disasters such as flash floods that occurred in the Cidurian Watershed. Hydrological design, especially for short-term phenomena runs generates the synthetic unit hydrograph. Snyder synthetic unit hydrograph is the common synthetic hydrograph that widely used on hydrological analysis. Generally, on the snyder synthetic unit hydrograph, the coefficient value (peak coefficient, time coefficient, CW75 and CW50) is only based on estimates or previous research so that the calculation of discharge is less accurate and needs further research. This study discusses the prediction of the value of the Peak Coefficient (Cp), Time Coefficient (Ct), CW75 and CW50 in the Cidurian Watershed using the Snyder Synthetic Unit Hydrograph (HSS) and get a calculation graph between the Polynomial and Collins Unit Hydrographs against the Snyder Synthetic Unit Hydrograph (HSS) in the Cidurian Watershed with rainfall data processing using the Thiessen Polygon, Mononobe, and Alternating Block Method (ABM). The results showed that the value of Peak Coefficient (Cp) = 0.59, Coefficient of Time (Ct) = 0.09, CW75 = 1.22, CW50 = 2.14, with Peak Discharge (Qp) Collins Measured Unit Hydrograph 19th hour = 1.589 m3/s, and Peak Discharge (Qp) Snyder Synthetic Unit Hydrograph 11th hour, 1 = 1.59 m3/s.

Abstract

Building construction in Indonesia has increased rapidly; according to the BPS (Badan Central Statistics), in 2020, building construction from 2016–2019 will have 189 buildings in Jakarta. The construction includes apartments, hotels, offices, and campuses. While productivity measurements are useful as information for the company to evaluate the trends of its productivity developments over time, information from these results will later be used for reference in correcting previous shortcomings. This research aims to determine how long a tower crane’s cycle time, productivity, and operating costs are. This research was carried out on the construction project of the State Islamic University of Sultan Maulana Hasanuddin Banten. The study was conducted by observing the tower crane for six days. From data collection, whether cycle time, productivity, or operating cost, the data analysis used in this study is an analysis using productiveness formulas, cycle times, and operating costs. From the analysis of the data, it can be known that the cycle time of the tower crane heavy tool on April 25, 2022, to April 29, 2022, gained an average of 0.311 hours for the average productivity of the tower crane on April 25, 2022, until April 29, 2022, which is 9662.131 kg/hour, while the operating cost of the crane tower was Rp. 575.037.37 per hour

Abstract

The increasing number of COVID-19 cases in Indonesia has caused a decrease in the number of users of public transportation services, one of which is users of train transportation services. This makes some facilities at the station require adjustments to the applicable rules. The purpose of this study is to measure the level of satisfaction and importance of train station service during the COVID-19 pandemic, determine the gap between the level of satisfaction and importance, and determine the attributes that are prioritized for improvement. This research uses Service Quality and Importance Performance Analysis methods. The results of the data analysis show that the expected station services are not in accordance with what is received by users of Serang Station services. It is necessary to improve the quality of service and increase the number of facilities at the station to increase the satisfaction of service users who use Serang Station services.

Abstract

Transportation is one of the driving forces for growing a region. Increase in population and the economic growth of a region resulted in the community needed facilities are increasing. One of the cities that is also experiencing development is Malang City, one of which is Ki Ageng Gribig road which is the access to Malang-Pandaan toll road. This study aims to determine the degree of saturation of Ki Ageng Gribig road section which is around Pandaan-Malang toll gate. This study used a quantitative method and was guided by the 1997 Indonesian Road Capacity Manual. The research was conducted on two sections of the road, before and after entering the toll road. Based on the data obtained from the research survey, the road capacity results were 1473.45 pcu/hour, with a Q value of 2476.1 pcu/hour on road section 1 and a Q of 3230.9 pcu/hour on road section 2. Then, the degree of saturation value obtained at peak hours on the road section 1 is 1.68 and section 2 is 2.19. Both sections of the road have an F value which indicates that this road segment is in a saturated condition. So that attention is needed from the community, especially road users, so that they can pay attention to land use on urban roads so as not to disturb the flow of traffic on Ki Ageng Gribig road.

Abstract

Paving block is a building material composition made from a mixture of portland cement or other hydraulic adhesives, water and aggregate with or without other additives which do not reduce the quality of the concrete. This study aims to analyze the compressive strength of paving blocks from the utilization of local sand and palm shell waste. Palm shell waste is obtained from PT. Tapian Nadenggan who processes palm oil into palm oil. The large amount of waste can be used as an added ingredient in the manufacture of paving blocks. This research method is an experimental research, by making hexagon-shaped paving blocks with a mold size of 20 cm wide, 12 cm side and 6 cm thick using estuary sand and palm oil shell ash waste with variations of 0%, 25%, 50%, 75%, 100%. The addition of ash from palm shell waste resulted in an effective compressive strength test at 28 days of age with the highest value at 50%, namely 17.64 MPa, then a 25% variation, namely 17.38% and a 75% variation with a value of 16.03%, classified as quality B can be used for parking lots. Meanwhile, the 100% variation with a yield of 11.03 MPa is included in grade D and can be used for garden.
