Abstract

Water is a very important need for life on earth, especially living things such as humans, plants, animals and others. To meet these water needs, humans make various efforts to get it. Energy loss is a factor that affects the capacity of pipes as a means of conducting the flow of both water and oil. Energy loss leads to a reduction in flow discharge. Energy loss is caused by several factors including the roughness of pipe walls. In general, in a pipeline installation, two types of energy loss are known, namely energy loss due to friction and energy loss due to changes in miners and other accessories. From the test results, the largest energy loss occurred in the 3/4 pipe (P1 and P2) inch of 0.0092 m, also having a large flow speed of 0.579 m / second. The cause of the large energy loss due to friction between fluid and pipe walls or called major losses (hf) in normal pipes is greater than pipe cross-sectional changes and pipe bend resistance. Meanwhile, the flow speed in a normal pipe with a diameter of 2 inches has a flow speed of 0.080 m / s and an energy loss of 0.0000657 m and a flow speed in a normal pipe with a diameter of 3/4 inch has a flow speed of 0.571 m / s and an energy loss of 0.0033 m.

Abstract

Flooding is a seasonal threat that occurs when water overflows from existing channels and inundates the surrounding area. Floods are the most frequent and most detrimental natural threat. Sinrijala Canal is a channel that drains water from the Pettarani region to the sea through the Pannampu Canal with a length of 2.36 km. The canal serves as an urban drainage and as the main base for flood control. The method used in this study is quantitative method. This research method can be done by collecting data and processing data so as to produce data that can solve research problems. Sinrijala's current drainage condition does have several problems, especially in the physical building. The flatness of the channel base and the reduced carrying capacity of the channel are caused by sedimentation. Therefore, handling is needed in the form of normalization activities in the form of dredging regularly and periodically. The channel discharge in the Sinrijala Canal is smaller than the puddle discharge so that the capacity of the canal drainage channel cannot drain or accommodate the amount of inundation in rainy conditions so that there is an overflow of 313.31 m3 / second. Sinrijala canals are declared ineffective for flood control because the flood discharge exceeds the discharge capacity that can be accommodated by the canal channel.

Abstract

Water requirements in irrigation are very variable depending on land conditions and management. This research aims to determine the mainstay discharge in the watershed and water availability to meet water needs in Kalukku, Mamuju district. These needs include evaporation, plant needs, and water loss. Therefore, it is planned to determine the amount of reliable discharge that can be relied upon for water availability in the Kalukku watershed and the value of raw water availability in meeting water needs in irrigation areas in Kalukku. The aim of this research is to determine the amount of reliable discharge that can be relied upon for water availability in the Kalukku watershed and to determine the value of raw water availability in meeting water needs in irrigation areas in Kalukku. This research focuses on the irrigation area of the Kalukku River through the wide Kalukku Dam. The research results show that the mainstay discharge (Q80) of rainfall is 21.96 m3/sec, Q50 is 39.00 m3/sec, and Q20 is 60.06 m3/sec. The availability of irrigation water in D.I Kalukku is sufficient to meet the needs of rice plants in three growing seasons. There is a water surplus in MT1 and adequate supply in MT2 and MT3. This shows that D.I Kalukku has sufficient water supply for rice farming in that planting season. The availability of irrigation water is 128.9 m3/sec while the irrigation requirement is 17.7 m3/sec. This shows that there is enough water available to meet the needs of plants in MT3.

Abstract

Flooding is the most frequent natural disaster in Indonesia. It is defined as a condition in which a region is submerged by a large volume of water due to high rainfall. Takkalasi Village, through which the Takkalasi River flows, is considered a flood-prone area. Given the recurring floods, a comprehensive study is needed to find solutions. This research was conducted in Barru Regency, specifically in the Takkalasi River, aiming to analyze rainfall intensity and flood discharge for 25, 50, and 100-year return periods, as well as flood control methods. The planned flood discharge was analyzed using the Nakayasu Synthetic Unit Hydrograph (HSS) method, yielding 25-year (Q25) discharge at 77.22 m³/s, 50-year (Q50) at 78.64 m³/s, and 100-year (Q100) at 79.97 m³/s. Analysis showed river overflow at 67.888 m³/s, indicating that when both high tides and continuous rainfall for up to 7 hours occur, flooding affects the Takkalasi area. To mitigate this, the construction of two water gates along the Takkalasi River is necessary to prevent overflow during such events.

Abstract

The primary causes of watershed degradation are the loss of vegetation in permanent land/forests and the inappropriate use of land. Given the current condition of the Saddang River, it is highly susceptible to flooding, especially during periods of heavy rainfall. This situation is exacerbated by changes in land use. Flooding in the Saddang watershed occurs almost annually during the rainy season, particularly in the lower reaches encompassing the districts of Duampanua, Cempa, and Patampanua. This study aims to determine the impact of land use changes on flood discharge in the lower reaches of the Saddang watershed. The research employed a quantitative approach, utilizing daily rainfall data for hydrological analysis and land cover data for land use change analysis. The Mononobe method was used to calculate rainfall intensity, while the Nakayasu Synthetic Unit Hydrograph (SUH) method was applied to compute design flood discharge. The results revealed a 7.79% change in land use between 2012 and 2021. This change led to an increase in the surface runoff coefficient (C). Consequently, there was an 8.93% increase in flood discharge during the 2012-2021 period, attributed to the higher runoff coefficient resulting from land use changes.

Abstract

Currently, soil stabilization is being developed using environmentally friendly chemicals. This material is called Soil Stabilizer Solution. This research aims to analyze the characteristic and mechanical properties of soil and analyze the effect of adding soil stabilizer solution and cement on CBR values. Soil plays an important role as a supporting foundation. So from the mixing method applied to mechanical measurements on real soil, the compaction measurement uses 5 soil samples of 100% of 2kg weight without cement and SS solution, as well as the addition of 1.5% SS solution with a fixed composition using 100% soil without cement, and with the addition of 1.5% SS solution plus 4%, 6%, 8% PCC cement which reduces the soil so that the soil used is 96%, 94% and 92% of the total weight of the soil. For CBR, 3 original soil samples are used and the composition of each variation the same, with a sample weight of 5kg, the CBR value of the Original Soil is 10.22% while the increase in adding 1.5% SS Solution + 0% Cement is 18.70%, as well as the increase in adding 1.5% SS Solution + 4 %,6%,8%, experiencing an increase respectively, namely 26.85%, 31.71% and 44.79%, the use of SS solution and PCC cement for soil stabilization can increase the CBR value in the bearing capacity of clay soil.

Abstract

Sultan Hasanuddin International Airport experienced an average growth in passengers and aircraft movements for the 2014-2018 period, respectively 11.35% and 9.29% per year. Therefore, in order to improve service, airport development is being carried out referring to the Sultan Hasanuddin Airport Master Plan, including a parking building for 4-wheelers with a capacity of 624 SRP, while the existing 4-wheeled parking capacity is 1,072 SRP. So that data was collected on the number of passengers during peak hours, data on the number of vehicles and data on the duration of each vehicle's parking in 2018 before the airport development was carried out. From these data, a calculation of the need for parking space is carried out during peak hours as well as a calculation of the availability and need for parking space based on the length of time each vehicle is parked. So that the need for parking space during peak hours is 1,183 SRP, and the required capacity based on the characteristics of the length of time each vehicle is parked is 989 SRP/hour. While currently being developed is 624 SRP with a capacity based on the long parking characteristics of each vehicle is 522 SRP./hour. From the results of these calculations it can be concluded that the development of stage 1 is not able to serve parking needs during peak hours, so that additional parking space capacity is needed.
