Water requirement in Pesanggaran is rice fields, while the availability of irrigation water is obtained from rainfall and irrigation discharge. The water balance is calculated by using a tool such as the Water Evaluation and Planning (WEAP) where the results of the WEAP are in the form of a broad percentage of water coverage that can be covered (Coverage). The results of the WEAP calculation are in the form of Coverage as a reference in calculating profits for each year. Optimization in the Very Dry and Normal Year is the existing of where the start of planting begins in December period 1 while the optimize has the start of planting in the December period 3 in the Dry and Wet Season. WEAP optimization is seen in the number of Coverage values where the coverage value for a Dry Year before optimization is 99.34%, and after optimization is 100%, Wet Year before optimization is 99.1%, and after optimization is 100%, for Very Dry Year Coverage value is 95.69%, and Normal Year Coverage as 99.16%.

Progo River is one of the rivers that originated in Merapi Mountain. It is one of the active volcanoes, and if it erupted, so it resulted in an abundant material or sediment. The material from its eruption transported by water discharge will become a debris flow, that it gave damage and losses on infrastructure and inhabitants living around riparian areas. Based on the background, therefore, it is essential to do a research-related infrastructure and population in a riparian zone. The research objective is to study the accordance of the condition of the riparian zone of downstream Progo River based on the established rules. The method used was a field survey assissted by the application of Survey123 for ArcGIS. The data processing used ArcGIS software. The research result shows that some locations are not by the established rules on riparian areas. One of the most significant places having the highest settlement percentage included in riparian areas is Jatisarono Village Nanggulan Subdistrict, with the area of settlement of 0.1224 km square and 44.07% for the riparian zone with 50 m width and 0.1766 km square while 21.16% for the riparian zone with 100 m width. Jatisarono village also becomes the village with the highest approximate population number within the riparian zones with 135 people in the riparian zone with 50 m width and 195 people the riparian zone with 100 m width. From the field survey result, it finds that 13 rivers infrastructures along the downstream Progo River consisting of 10 bridges, two dams, and one groundsill (sample) are still in reasonable good condition.

Jakarta is a province in Indonesia with a rapid population growth. Data obtained from the Jakarta Central Bureau of Statistics shows that Jakarta had a population of 102.776 in 2016, increasing to 103.742 in 2017. This rise in population and the role of Jakarta as the center of the economy have led to an uncontrolled increase for the need of different transportation modes. Based on the Jakarta transportation statistics (2017), the number of motorized vehicles in Jakarta reached 20.972.175 units, while the toll road built was only 7.094.000 meters. So it can be concluded that each vehicle only got 0.3382 meters of space. According to data obtained from Numbeo in 2019, Jakarta ranked 5th as the biggest contributor to congestion in Indonesia with a congestion index of 274.39. In order to overcome these problems, various efforts need to be taken, one of which is by implementing Electronic road pricing in several roads in Jakarta which is considered to be one of the solutions to reduce congestion. The purpose of this study is to analyze the potential and problems that arise in the application of Electronic road pricing on Jenderal Sudirman road, Jakarta. The research method used is a combination of literature study and survey using a questionnaire. To achieve effectiveness and efficiency of the electronic road pricing system, studies are carried out in various aspects, so that Electronic road pricing can be one of the solutions to traffic congestion in Indonesia. Based on the result of study, it can be concluded that electronic road pricing implementation can be a solution for traffic congestion especially on Jenderal Sudirman Road, Jakarta if the implementation is integrated with public transportation.

Global warming is a serious environmental issue. Production process of Portland Cement (SP) contribute 5% of all carbon dioxide emissions, the main cause of global warming and making cement means making pollution. High Volume Fly ash (HVFA) concrete technology is one solution that can be offered to overcome this problem. HVFA concrete is a type of concrete made using high enough fly ash, which is more or equal to 50% by weight of cement. In this study, the use of fly ash (FA) as a cement replacement material is about 50%. One disadvantage of HVFA concrete is the low early strength or slower, so in this study HVFA concrete was made with coarse aggregate size to smaller. This study compared HVFA concrete beams with size of aggregates are 20 mm and 4.75 mm, the planed compressive strength (f’c) is 25 MPa. Fly ash will substituted by 50% of the weight of the cement and the addition of superplasticizer about 0.4% by weight of cement. The size of specimens for flexural capacity of reinforced concrete beams about 140 x 240 mm with a span of 2000 mm. The flexural strength test arrangement with two-point loading. And the results of the study showed an increase in flexural capacity of 13.38%.

Dynamic behavior and system identification are important topic in monitoring and maintaining existing infrastructures. System identification using Frequency Domain Decomposition (FDD) is an operational modal analysis (OMA) in frequency domain used on experiment of shear frame model with random vibration method is validated by comparing output of FDD data using acceleration input from simulated model with output of FDD using acceleration result of experimental model. The result of acceleration data is recorded using USB accelerometer X16-1D then calibrated and analyzed using Matlab programs, data_procces.m and solve FDD_eksperiment.m to estimate the modal parameter of model structure. Compared with parameter modal of simulation model, FDD method with input simulated acceleration resulted in difference of 1.757% in first frequency and 0.462% in second frequency. Meanwhile for FDD method using acceleration of experimental model, resulted in difference of 6.3126% in first frequency and 7.7327% in second frequency. FFD method is fairly accurate in predicting the frequency of structure, but for difference of mode shapes in experimental is very big compared to simulated model therefore it can be concluded that, this modal parameter is cannot be detected in experimental model.

Sinduadi urban settlements with rapid population growth as a result of the growth of property, shopping, industry, campus and tourism businesses have the potential to create slum areas. Based on the 2016 Sleman Regent Decree in RT 011 RW 026 Kutu Dukuh have an area of 1.23 hectares of slums. To decrease size of slum areas, it is necessary to study calculations in accordance with applicable regulations. The purpose of the study was to identify the parameters determining the slum, calculate slum scores, reduction in slum area and slum level at the end of 2018. Data were taken from survey results and the Sleman KOTAKU Program document. From the analysis of slum measurements with 19 parameters the value is 23 (light slum category) measured based on PUPR Regulation No. 2/2016 which uses 7 aspects and 19 parameters, such as the limitations of building conditions, roads, clean water, waste management, drainage and the unavailability of hydrants. The initial calculation results show a score of 23 consisting of the unavailability of drainage value of 3, a waste management system that does not conform to the technical standard of value 5, the non-maintenance of waste management facilities and infrastructure of value 5, and the unavailability of a fire protection facility of value 5. For handling investment is required in the form of paving roads ( 853.5 m2), rainwater infiltration wells (18 units), drainage channels (154.5 m1), public hydrants (HU) clean water (10 units) and 3R waste (39 kk) which become the final score of 14 (< score 19) which means not slum.

Precast reinforced concrete beams are building structures without using on-site casting and can shorten construction time and reduce costs and labor. In this research a method was used to overcome the shortcomings of the precast method in terms of weight and size, by dividing the precast segment into a new connection between the beam to the beam where the connection was reinforced with Carbon Fiber Reinforced Concrete (CFRP) and Steel Plate. Where there are 2 beam joints namely Type II connection on the connection area, steel plate and bolt data are used as Type III washers and joints, CFRP is added to the joint area and 6 mm thick steel plate and 20 mm diameter bolt. The dimensions of the beams used are 150 x 250 x 3200 mm with 4P10 longitudinal reinforcement as pressure reinforcement and 2P10 as pressure reinforcement. While 2P8-200 as shear reinforcement in the field area, 2P8-150 for connection area and 2P8-100 for support area. Where the quality of reinforcing steel in this method is BjTP 24, with a yield stress of 323.533 MPa for P10 and 237,249 MPa for P8. According to the results of the study the beam joints with centralized loading, the type II joint beam obtained a load capacity of 2782,718 kg while the type III connection experienced a load increase of 3553,875 kg due to the addition of CFRP layers on the beam joints.

Lumpur Sidoarjo (Lusi) is an environmental issue in Indonesia that produce wasted soils, specifically clay soils, distributed to Porong River which causes a greater problem. Cement treated clay (CTC) becomes one of the solutions to overcome the problems caused by Lusi due to its ability in improving the strength of clay soils. This paper investigates CTC with lower cement amount (C <70 kg/m3) for reclamation and higher cement amount (C >150 kg/m3) for deep mixing marine clay for its strength and degradation due to the attack of magnesium sulphate as the main component of seawater which cause the degradation of CTC. The enhancement of soil strength is investigated by unconfined compression test (qu) and the degradation by penetration test. Water content of the specimens for both tests are arranged in its liquid limit condition (60%) and two times of its LL (120%). The result of the cement amount addition for both water content shows the enhancement of qu represented by linear and the tip resistance is increased. The characterictic of degradation for lower cement amount with close range present similar depth of deterioration, like-wise higher cement content. The value of tip resistance is not relatable with qu.
