Road pavement commonly undergoes damage due to factors such as heavy traffic loads, weather conditions, temperature variations, and inadequate construction practices. To enhance the strength of pavement structures, the utilization of asphalt mixtures with new specifications, particularly PG 70 modified asphalt, becomes essential. The main objective of this study is to assess the durability of the asphalt after 7, 14, 21, and 28 days in terms of Marshall parameters. This experimental research involves creating an initial sample consisting of 12 specimens with asphalt contents of 4.5%, 5%, 5.5%, and 6% to determine the Optimum Asphalt Content (KAO). The samples are subsequently immersed for 30 minutes at a temperature of 60°C. Next, three test specimens are prepared for each planned asphalt content to undergo immersion for 7, 14, 21, and 28 days. The study reveals that the planned KAO is obtained at 6%, and after immersion for 7, 14, 21, and 28 days, the average durability values are 100%, 126.9%, 115.4%, and 127.4%, respectively. Therefore, it can be concluded that the incorporation of Portland cement improves resistance against mixture damage caused by continuous water immersion and enhances the durability value as the immersion period increases.

The Industrial Workers' Flats, located in the Batang Integrated Industrial Area, are supporting facilities workers use. The building was previously planned using conventional methods. In many cases, demands for fast and efficient construction work often occur, especially in the case of high-rise buildings. The need for multi-storey buildings encourages the need for an economical structural design that can be implemented quickly and efficiently without reducing the stiffness between the components of the building structure. From the explanation above, it is re-planned using the precast concrete method so that the work is neat, precise, and fast. In this planning, the SRPMK system is used. It needs good supervision in precast concrete, especially in joints, because precast joints are not as monolithic as conventional ones. It is necessary to develop precast technology to be more innovative in its use and easier to apply.

Development activities always cause environmental damage and/or pollution. This development triggers the acceleration of the phenomenon of climate change which should be a natural phenomenon. This research aims to empower the community with a community development process which consists of the stages of program planning, planning, implementation, evaluation & results of changes, and termination. The community development process was carried out using a qualitative approach and case studies in the field involving 3 informants consisting of the Blawi Village government, Karang Taruna, and the Blawi Village community who were directly involved in the Biopori Program and the Clean Village Program. The selection of informants was carried out to dig deeper into community development in the Biopori Program and the Clean Village Program. Biopori is a simple technology that can increase rainwater absorption and the amount of clean water reserves in the ground during flood control efforts. Clean Village is a simple tool to increase public awareness of the importance of clean houses for public health and flood control efforts in Blawi village. The result of this activity was the planting of biopori, the installation of 40 biopori holes in each community unit in Blawi Village was carried out as a pilot to be developed and carried out by the residents themselves.

The development of West Outer Ring Road, abbreviated as JLLB, to improve the quality of infrastructure in the City of Surabaya. A breakthrough is needed by opening a new existing road section to break down traffic jams that lead to the main corridor section of the central city. The JLLB area, originally a green open area, was converted into a road area. This condition will cause changes in the sum of rainwater runoff that occur. The JLLB also intersects with the railroad tracks. A drainage system plan to ensure no puddles on the road, even through the railroad tracks. The method of this study follows hydrological and hydraulics analysis of the drainage systems. The results of drainage analysis on West Outer Ring Road, abbreviated as JLLB, there are several typical canal dimensions needed. All velocities can be controlled in the range of permissible velocity. The minimum velocity is 0,4 m/sec, and the maximum is 0,873 m/sec. The maximum planned discharge is 1,381 m3/sec. The capacity of boezem is planned to suit 5,104 hr of rain duration. Based on all that results, the drainage analysis of JLLB would be great if implemented according to plan.

This study aims to analyze the application of Precast Half Slab formwork with conventional formwork in terms of cost, time, and implementation stages. The method used in this study is the precast half slab method. The Batang I Industrial Worker Flats project is in the Batang Integrated Industrial Estate. In the highly advanced construction era, many projects compete to innovate to produce a fast and efficient building. This Project uses the precast half slab method, where half of the floor slab is printed offsite (precast) with a thickness of 7 cm, and the other half is in place (topping 5.5 cm). This final Project analyzes the precast half slab method used by comparing it to the conventional method in terms of cost and time, so it can be seen which method is more profitable. The precast half-slab method analysis focuses on calculating the direct cost of conventional half-slab precast in terms of materials, tools, and worker wages, as well as calculating the time needed for each job.

The irrigation area in Sigulai Village is a rain-fed rice field whose irrigation water depends on rainwater and mountains. So that during the dry season, the rice fields cannot be planted due to a lack of water availability. The purpose of this analysis is to determine the need for deep water for the construction of irrigation networks, the capacity of the pumps used and to analyze the rotation of the water supply to each paddy field. The results showed that the irrigation network in Sigulai Village, Simeulue Regency had 1 water pump to irrigate the rice fields. The irrigated rice fields are located on the back (back) of the technical irrigation network in Sigulai Village, Simeulue Regency, so that even though there is a technical irrigation network, irrigation water has not been able to reach all of the rice fields because the rice field elevation is higher than the canal elevation. The amount of water needed for one harvest is 22,809,600 M3/one harvest for a paddy field area of 42 Ha (rice, horticulture, crops). The time required for pump operation to irrigate 42 hectares of rice fields is 23 hours 45 minutes/day with a pump capacity of 8000 (ltr/hour)

Evaluating the availability of irrigation water is a paramount phase in planning and managing an irrigation network system. This research aimed to calculate the availability and demand of irrigation water in the area of Blang Rongka, Timang Gajah Subdistrict, Bener Meriah District. Blang Rongka irrigation waters 81 hectares of rice fields from the Peusangan watershed. There are 408 households in Blang Rongka Village, with an estimated population of 1.418 people, consisting of 743 men and 675 women, with 43% of the population working as farmers. The data used in this research were primary and secondary. Preliminary data includes flow velocity, channel dimension, and a set of questionnaires. Secondary data includes irrigation network schemes, topography, demographics, and climate data. In addition, we also measure water discharge using the buoy method (manual) by finding the cross-sectional area and flow velocity. This research showed that the average value of water availability is compatible with the cropping pattern (paddy – palawija – paddy). The level of farmers’ satisfaction with irrigation was 80% while the level of water adequacy was 85%. The results have proven that the current irrigation is highly beneficial for farmers.
