A Analisis Neraca Air pada Daerah Irigasi Cipalih Kecamatan Ciamis
The Cipalih Irrigation Area Cipalih is an irrigation system located in the Ciamis District, utilized as a water source for agricultural and livestock management. The primary water source for the Cipalih Irrigation Area is the Cipalih River, which is capable of irrigating 641.368 hectares of rice fields. However, a problem persists in the Cipalih Irrigation Area where water shortages frequently occur during certain seasons, affecting the planting patterns in the area. Given the extensive coverage of the irrigated land, it is necessary to calculate the water balance to determine water availability and demand. This ensures the sustainability of the farmers' livelihoods by establishing an optimal planting schedule. The objective of this study is to determine the water balance conditions and planting patterns in the Cipalih Irrigation Area. This research employs a quantitative method, utilizing primary data (interviews with local residents and documentation) and secondary data (10-year rainfall data from three stations, river discharge data, climatology data, and technical irrigation data). The analysis of the water balance and planting patterns was obtained through planting pattern simulations. The results indicate that the water balance in the Cipalih Irrigation Area, based on these calculations, remains in surplus (excess water) throughout all months. Furthermore, the optimal planting pattern was identified as the 7th alternative, which consists of a Rice-Rice-Secondary Crop (Palawija) cycle

ANALISIS PEMILIHAN MATERIAL DINDING BATA MERAH DAN BATA RINGAN MENGGUNAKAN METODE SWOT ( STUDI KASUS DI KOTA BANJAR )
Walls are a crucial element in construction projects, serving as roof supports, room partitions, and weather barriers. Traditional materials commonly used are red bricks, made from molded and fired clay, with standard dimensions of 20 cm x 11 cm x 5 cm. While red bricks are considered robust and readily accessible, they weigh up to 250 kg/m², which can increase the structural load and material costs due to greater adhesive requirements. This study employs interviews and questionnaires to gather data from users, workers, and material suppliers as a basis for analysis. The data collected consists of two types: primary data obtained directly through field surveys, including interviews and questionnaires, and secondary data sourced from other references, such as the AHSP DPUTR in the case study area of Banjar City. The analysis reveals that lightweight bricks, made from a mixture of cement, lime, and expanding agents, offer advantages in strength and market potential. Lightweight bricks have dimensions of 20 cm x 60 cm x 8-10 cm and weigh only 57.5 kg/m², making them 4.34 times lighter than red bricks. Despite the efficiency of lightweight bricks, the unit price in Banjar City remains higher, at Rp 125,000.00/m² compared to Rp 117,062.55/m² for red bricks. This research provides valuable insights for the community in selecting wall materials, considering specific needs and the existing construction context

The rapid advancement of construction technology drives innovation in the use of concrete materials to meet the needs of sustainable development. One such innovation is the incorporation of additional materials into the concrete mix. This research aims to examine the influence of adding coconut fiber as an additive on the compressive strength and modulus of elasticity of concrete. Concrete is a mixture of Portland cement or other hydraulic cements, fine aggregates, coarse aggregates, and water. An experimental method was employed using coconut fiber as an additive to fine aggregates. Tests were conducted on 28-day-old concrete with cylindrical specimens measuring 150 mm in diameter and 300 mm in height. The variations in coconut fiber addition were 0% (normal concrete), 0.125%, 0.25%, 0.35%, and 0.45% of the weight of the fine aggregates. Based on the research findings, the average compressive strength at 28 days for normal concrete was 22.94 MPa. The addition of 0.125% coconut fiber reduced the compressive strength to 19.73 MPa (a decrease of 13.99%), and the addition of 0.35% fiber further reduced it to 18.00 MPa (a decrease of 21.54%). However, the addition of 0.25% fiber increased the compressive strength to 24.38 MPa (an increase of 6.32%), and the addition of 0.45% fiber resulted in the highest increase in compressive strength, reaching 27.28 MPa (an increase of 18.94%). Meanwhile, the average modulus of elasticity for normal concrete was 1663.52 MPa, with a decrease of 92.61%. The addition of 0.125% coconut fiber increased the modulus of elasticity to 2109.63 MPa, but with the addition of 0.25%, 0.35%, and 0.45% fiber, the modulus of elasticity decreased to 1401.09 MPa (a decrease of 93.96%), 782.00 MPa (a decrease of 96.08%), and 634.20 MPa (a decrease of 97.42%), respectively. Thus, it can be concluded that the addition of coconut fiber as a fine aggregate additive impacts the variation in compressive strength and the reduction in the modulus of elasticity of concrete.

Pengaruh Beban Muatan Berlebih Terhadap Umur Rencana Perkerasan Lentur (Studi kasus Ruas Jalan Bandung - Tasikmalaya KM 77 - KM 79
This study aims to analyze the impact of overloading on the design life of flexible pavement using the AASHTO 1993 Method, with a case study on the Bandung - Tasikmalaya Road Sector, KM 77 - KM 79. This road is frequently traversed by overloaded vehicles, which can lead to accelerated pavement deterioration and a reduction in the road's design life. Traffic data, vehicle loads, and existing pavement conditions were utilized to calculate the influence of overloading on the increase of the Equivalent Single Axle Load (ESAL) and to compare it with the pavement design life calculated based on the AASHTO 1993 Method. The calculation results demonstrate that the percentage of overloading significantly reduces the road's design life. The Vehicle Damage Factor (VDF) for normal loads over a 10-year design life is $20,495,514.04$ ESAL, whereas for overloaded conditions, it reaches $33,083,921.23$ ESAL. This 47% increase in the cumulative VDF value causes the road's service life to last for only 4 years out of the total 10-year design life. To maintain road functionality throughout the 10-year design life, an overlay thickness of 3.83 cm is required with a Resilient Modulus of 2,000 MPa and a minimum Marshall Stability of 800 kg. Alternatively, an overlay of 3.26 cm is needed for Modified Asphalt Concrete (Laston Modifikasi) with a Resilient Modulus of 3,000 MPa and a minimum Marshall Stability of 1,000 kg, with the material applied at approximately 5 cm before compaction.

ANALISIS HUBUNGAN VOLUME, KECEPATAN DAN KEPADATAN LALU LINTAS DENGAN METODE GREENSHIELD DAN GREENBERG
Ibrahim Adjie Road Km 101+700 in Indihiang District, Tasikmalaya City is a national road with a two-lane two-way undivided (2/2 UD) configuration that plays an important role in connecting various centers of community activities. High traffic volumes during certain periods, combined with relatively high side friction, result in a decline in traffic performance and level of service. This study aims to analyze traffic characteristics in terms of volume, speed, and density, as well as the relationships among these parameters using the Greenshield and Greenberg methods, and to compare the resulting road capacity and level of service with those obtained from the Indonesian Highway Capacity Manual (PKJI) 2023. The results show that based on traffic volume analysis conducted over seven days, the peak traffic volume occurred on Thursday from 16:00 to 17:00 WIB, reaching 2,004 pcu/h. Analysis using PKJI 2023 yielded a road capacity of 2,425.59 pcu/h, resulting in a degree of saturation (Ds) of 0.83, which corresponds to Level of Service D (LOS D). The analysis of the relationships among traffic volume, speed, and density using the Greenshield and Greenberg methods indicates strong correlations, with the coefficient of determination (R²) for the fundamental speed–density (V–D) relationship exceeding 0.90. The capacities obtained from the Greenshield and Greenberg methods are lower than those from PKJI 2023, amounting to 1,854 pcu/h and 2,154 pcu/h, respectively, corresponding to Levels of Service F and E. These differences indicate that PKJI 2023 represents ideal traffic conditions, whereas the Greenshield and Greenberg methods better reflect actual field conditions influenced by side friction and driver behavior.

EVALUASI PENGENDALIAN WAKTU MENGGUNAKAN METODE CRITICAL PATH METHOD (CPM)
In the construction of a construction project, there must be a timing of a project, and control of the cost of the project. In its implementation, sometimes the two things deviate from what has been planned, so it is necessary to do the control and management of a project. Besides being seen from quality, the success of a project can also be seen from the point of view of cost and time control. Time is an important interrelated element in the management of a project. Where time delays can determine how much expenditure is spent on the project, so delays need to be prevented and controlled to prevent it from happening. To restore the level of progress, the scheduling method of CPM can be used to obtain the optimal duration of project activities. This research will evaluate the project of building a pharmacy building in Pangandaran district that has been reviewed in terms of time so that it is expected to minimize the time delay that occurs, so that the project control can be implemented properly. Therefore, time control is required in completing the work project.

ANALISIS PENGENDALIAN WAKTU DENGAN MENGGUNAKAN METODE EVM PADA PROYEK JALAN RAYA LINGKAR UTARA TASIKMALAYA
It is important to know that in a project there is always cost and time control, it is generally called project management. Project management is everything related to planning, implementation, control and coordination in a project from the start of a project until the end of the project period to ensure all implementation of the project runs on time and with the right quality. The purpose of this study is to determine time control using the Earned Value Management method in the North Ring Road Development project in Tasikmalaya City. This earned value method can integrate time in controlling a construction project and is one of the performance indicators. The concept of earned value management (EVM) is to compare costs with schedules in the realization that occurs in the field. The three parameters used in this EVM method that are used as analysis are: BCWS (Budget Cost of Work Scheduled), BCWP (Budget Cost of Work Performed) and ACWP (Actual Cost of Work Performed). Delays and deviations in the project can be identified by looking at the values ​​of CV (Cost Variance) and SV (Schedule Variance). This method can also be used to determine the efficiency of resource use in the form of a cost performance index (CPI) and a schedule performance index (SPI) and can determine the estimated total project cost (EAC). This study shows that the Earned Value Management (EVM) method can control time and costs in the Tasikmalaya North Ring Road Construction project, this is indicated by the performance index value (CPI) = 1 which indicates that the cost is quite good, this is because the costs incurred AC (Actual Cost) is the same as the value obtained EV (Earned Value). And the schedule/time performance index SPI obtained an average value of SPI> 1 which indicates that the schedule performance is very good so that the work can be completed as expected because it is able to achieve the planned work target.
ANALISIS FUNGSIONAL JALAN MENGGUNAKAN METODE INTERNATIONAL ROUGHNESS INDEX (IRI) DAN SURFACE DISTRESS INDEX (SDI) PADA RUAS JALAN CIAMIS – KAWALI (STA 16+000 – STA 19+000)
A road is infrastructure designed to connect various locations, allowing the movement of people, vehicles, and goods from one place to another. Roads are typically equipped with hard surfaces such as asphalt or concrete to support the weight of vehicles and facilitate faster and safer travel. Over time, roads will inevitably suffer damage due to various factors such as weather, vehicle loads, and others. Because of these factors, proper road maintenance is required. One way to determine the necessary maintenance is by analyzing the damage using the International Roughness Index (IRI) and the Surface Distress Index (SDI) methods. The IRI method involves measuring road roughness using an Android-based application called RoadlabPro. Meanwhile, the SDI method is obtained from visual observations and measurements of road damage in the field. The study results on the Ciamis – Kawali road section show a correlation coefficient (ratio) between the SDI and IRI values of r = 0.321, which indicates a weak correlation (ratio) as it falls within the range of 0 - 0.49. The average IRI value for road roughness is 3.25 m/km, indicating a good surface condition, while the average SDI value is 91.00, indicating a fair surface condition. The pavement condition is classified as fair, as the IRI is less than 4 and the SDI falls within the range of 50 – 100. Therefore, the type of pavement maintenance required for this road section is Routine Maintenance.
EVALUASI TINGKAT KERUSAKAN JALAN SEBAGAI DASAR PENENTUAN PERBAIKAN JALAN PADA RUAS JALAN WINDURAJA – WARUDOYONG (STA 0+000 - STA 3+000)
Roads play a crucial role in supporting economic, social, and cultural activities. However, various factors such as high vehicle volume, road age, and poor drainage can lead to road damage. This study aims to evaluate the level of road damage on the Winduraja – Warudoyong road section (STA 0+000 - STA 3+000) as a basis for determining the necessary repairs. The methods used are the Surface Distress Index (SDI) and Pavement Condition Index (PCI). The SDI method evaluates road damage based on the width and area of cracks, the number of potholes, and wheel ruts. Meanwhile, the PCI method assesses the condition of the pavement based on the type, severity, and extent of damage. The study results indicate that certain segments of the road are experiencing light to moderate damage, which may affect the comfort and safety of road users. By using the SDI and PCI methods, this study produces road damage values that can serve as a basis for determining repair priorities. The survey results show that the road surface condition has an average SDI value of 108, which is categorized as light damage. The average PCI value is 36, which falls into the poor category. The dominant types of damage found are alligator cracking, potholes, and ruts. The discussion of these results indicates that significant damage affects the comfort and safety of road users.

ANALISIS PENGARUH DILATASI BANGUNAN PADA GEDUNG 6 LANTAI BERDENAH L TERHADAP GEMPA DENGAN METODE RESPON SPEKTRA
Indonesia is one of the countries with a high frequency of seismic activity. The earthquakes that occur in Indonesia are caused by the vertical movement of two continental plates: the Indo-Australian and Eurasian plates. Furthermore, the island of Java is characterised by a multitude of active faults, which serve to elevate the risk of seismic activity in the region. Given the high potential for earthquakes in this region, it is crucial to prioritize earthquake-resistant construction planning, including the incorporation of dilatation techniques to mitigate seismic impacts. This research aims to elucidate the influence of building dilatation on a six-story L-plan structure subjected to seismic forces and ascertain the optimal dilatation gap distance for the Faculty of Engineering Building Center. The research method entails the analysis of the building structure using the ETABS program, with a comparison between structures with and without dilatation. The parameters analyzed include structural vibration period, inter-storey deviation, base shear force, and torsional irregularity. The calculation of the dilatation gap distance is carried out in accordance with the requirements of SNI 1726:2019. The findings of the analysis demonstrate that the implementation of dilatation in L-shaped buildings markedly influences the structural response to earthquake loads. The model with stiffer dilatation exhibited a smaller structural period of vibration and more restrained inter-storey deviation, while the model with more flexible dilatation demonstrated a larger period of vibration and larger inter-storey deviation. The safe dilatation gap distance of the Building Center building of the Faculty of Engineering was calculated to be 153 mm, which exceeded the minimum required distance.
