Abstract

Transportation problems in residential areas arise because of the movement patterns of people and goods and the development of land areas that are not in accordance with the capacity of the road network performance. In this case if the influence of the road network is not considered it will have an impact on the level of road services to be low, causing congestion, increasing the number of accidents, traffic violations and the function of the road itself. The development of subsidized housing aimed at low-income people in East Baturaja District has increased since 2017 with 722 houses. That is, with the increase in development can have an impact on housing traffic with the performance of the road network. The purpose of this study is to predict trip generation due to the construction of subsidized housing on the performance of the road network of subsidized housing areas in East Baturaja District. The problem in this study is knowing the character - istics of the respondents, then determining the variables that become the benchmark in this study are the Purpose of Leaving the House (X1), Total Revenue (X2), Total Expenditures (X3), Types of Transportation Modes Used (X4), Ownership Motorcycle (X5), Car Ownership (X6) and Transportation Costs (X7). The study uses quantitative methods and multiple linear regression analysis with sampling using a tiered formula and the proportional formula to take samples so that some regions are represented as many as 135 samples. From the results of the study there are four variables that meet, namely, X1, X2, X4, X2 and obtained the equation Y = -1.07 + 0.13 (X1) + 0.19 (X2) + 0.20 (X4) + 0.73 ( X5) and the price R2 = 0.79 is obtained. The effect of the trip generation on the road network is: 102.5 pcu / hour.

Abstract

The bathymetric mapping activity at sea requires sea tide data for the needs of the depth of measurement results. This manual tidal observation is carried out day and night without stopping for a certain period of time, so that a minimum of 4 people are needed to observe one observation station. This manual observation is prone to reading errors, especially at night. Basically there are currently semi-automatic and automatic tidal gauges for sale, but the price is quite expensive. In this study, tide gauges have been developed automatically and real time both in observations and in data transmission using ultrasonic and micro-controller sensor technology. The method used is a design by utilizing an ultra-sonic sensor and micro controller arduino uno, as well as a GSM module (Global System for Mobile Communications). Each device is connected to a micro controller then programming is done for the data retrieval process, calculation of water level, and sending data to mobile phones through the SMS (Short Message Service) facility. Testing the results of tidal measurements from the tools made was carried out in the hydro-graphic laboratory and then tested directly into the field around the coast of Lampung bay. This study produces equipment for measuring tides automatically and real time with ultrasonic sensors. The results of tidal measurements will be stored in a micro SD and displayed on the LCD screen, and sent to the destination number via SMS with the SIM module 800L v.2. The error rate generated from the field test is 1.833%

Abstract

This study aims to investigate the amount of clean water demand per capita in Bandar Lampung City, including the factors that affect the clean water needs, the amount of clean water consumption costs, and compare the results of research with clean water needs in Indonesia and other countries. The research location is in the Bandar Lampung City area which covers 20 sub-districts and 126 villages. Data collection on clean water needs was carried out using a questionnaire distributed to 126 households randomly. Based on the results of the analysis that has been carried out, it can be concluded that: (1) The amount of clean water per capita in Bandar Lampung, which is the sum of all types of clean water needs such as drinking/cooking, bathing, washing, and other needs for washing vehicles is 130.44 ltr/person/day. Factors that influence the need for clean water in the City of Bandar Lampung include: respondent characteristics, number of family members, education status, type of work, number of vehicle ownership, and ease of obtaining water. The cost of clean water needs issued by the people of Bandar Lampung City every month ranges from Rp. 127,267.00 up to Rp. 187,449, 0. (4) The results that obtained in this study are far different from the results of Kindler and Russel's (1984), which stated that the average water use for households is 295 liters / person / day. But the results obtained in this study approached the Planning Criteria Set by the Directorate General of Human Settlements, Public Works Agency in 1996, which stated that the Big City, which is a city with a population of 500,000 - 1,000,000 people, has domestic water needs about 120 ltr/person/day until 150 ltr/person/day.

Abstract

Road instalation is one of crucial sector which become connection zones of campus ITERA. Optimum planning of design pavement is very necessery. Variable that affected the planning process of pavement design on the road zone of ITERA is, CBR Subgrade value, Traffic loads factor, road classification, and pavement types. Pavement design of ringroad inside campus ITERA planned with 2 methods, the pavement thickness analysis method using Bina Marga 1987 and Pavement Design Manual using Bina Marga 2013. Based of survey and analysis obtained CBR subgrade with 6%-10%, traffic loads for 20Years reach 1.210.994, and region condition categorized as tropical climate with rainfall around 1900-2500mm/year. Pavement design with the pavement thickness analysis method using Bina Marga 1987 and Pavement Design Manual using Bina Marga 2013 resulted variation thickness, MDP2013 with flexible pavemet HRS WC, HRS Base, LPA class A and LPA class B resulted total thickness at 44cm while MAK1987 resulted at 35cm. Significant differences is in LPA class A and LPA class B. By the studies, total thickness with the pavement design manual 2013 is more thick than using the pavement thickness analysis using Bina Marga 1987, this caused by some standard in the pavement design manual 2013.
