Tinjauan Efektivitas Kanal Sinrijala Pada Jalan Sukaria dalam Pengendalian Banjir Kota Makassar

Tyas Maulida Sardinar — 2024-05-30

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.

Syamsu Alam — 2024-05-30

Sediment contained in the channel changes dimensions and can indirectly cause less optimum water flow. Sedimentation buildup in different waterways, field measurements were taken to determine the measured sediment volume and the capacity change in the Bpr.5-Bpr6 secondary channel caused by the influence of sediment. Data collection in the field was carried out in the parota secondary irrigation canal, which is located in the village of Sanrego, Kahu sub-district, Bone district. The data sources in this study are primary data obtained directly from field measurements and secondary data obtained from the literature. The volume of sedimentation in the secondary canal in the Sanrego irrigation network, Bone Regency is Bpr.5-Bpr6 is 707,903 m3, while the capacity of the secondary canal from the initial dimension of the canal with a cross-sectional area is 5.01 m2. After sedimentation, the cross-sectional area becomes 3,985 m2. with the initial discharge of the channel is 2.96 m3/sec. after sedimentation occurs, the channel discharge becomes 2.19 m3/sec.

Zainal Rifaldi — 2024-05-30

Irrigation system in paddy fields in Laliseng Village. distribute water to agricultural land by using gravity or allowing water to flow by itself in the field. This is considered ineffective because the channel used is only made simple without careful planning, this causes the water to flow more than the desired debit. And because this simple channel is unable to accommodate rainwater discharge, so that when it rains with high intensity the water can flow to the land instead of the channel it should be.Therefore it is necessary to analyze rainfall and channel discharge, to determine the design of irrigation canals that are in accordance with the planned flood discharge so that irrigation canals can work optimally. In conducting the research, primary data is collected in the form of channel dimensions and secondary data in the form of rainfall data and irrigation maps. The research results obtained trapezoidal channel dimensions with a channel width (b) of 1.4 m and a depth (h) of 0.60 m and accommodates a discharge channel of 1,166 m3/s.

Analisis Nilai CBR Dan Permeabilitas Tanah Lempung Yang Distabilisasi Dengan Fertilizer Di Desa Alam Buana Kabupaten Luwu Timur

Agus Hary Susetyo — 2024-05-30

In general, clayey soil has low bearing capacity; therefore, clayey soil needs to be improved in terms of its bearing capacity before constructing anything on it. This research aims to utilize fertilizer to enhance the CBR (California Bearing Ratio) and reduce the permeability of clayey soil. One way to improve clayey soil is by incorporating fertilizer as a soil stabilization material, by conducting CBR and Permeability Tests. Urea fertilizer readily dissolves in water and exhibits easy water absorption properties (hygroscopic). On the other hand, NPK fertilizer is a compound fertilizer containing nitrogen (N), phosphorus (P), and potassium (K) in varying compositions, with each element represented by the initial letter of its name (N, P, and K). In this study, 10% Urea is added to the soil, and there is variation in the amount of NPK, namely 0%, 5%, 10%, and 15%. The research results indicate that with the addition of NPK fertilizer, the CBR value continues to increase compared to the original soil and soil with only urea mixture. Meanwhile, in the Permeability Test, with each addition of NPK fertilizer, the coefficient of permeability value experiences a decrease.

Irrigation is an effort to bring in water by making it buildings and channels to paddy fields or fields according to plant needs. Around 86% of national rice production comes from irrigated rice fields. The aim of this research is to determine the irrigation system for rainfed rice fields and sources of rainfall water for irrigation of rainfed rice fields in Tompobulu District, Bantaeng Regency. This research method uses a qualitative descriptive method, with data collection techniques, namely surveys and observations. The results of the analysis show that the Tompobulu District Irrigation Area uses a non-technical irrigation system where the irrigation network is usually managed independently by farmer groups by relying on rainfall in rice fields without permanent buildings. The irrigation area has an irrigation area of 557 ha. The source of irrigation for rainfed rice fields in Tompobulu District comes from rainfall that falls directly on the rice fields to be used as a source of irrigation water in the irrigation areas.

Analisis Kehilangan Energi Pada Pipa PVC Akibat Belokan Dan Perubahan Penampang

Ramdan Ramdan — 2024-05-30

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.

Renaldi Z Renaldi — 2024-05-30

Clay soils in general can be said to have a low carrying capacity. Therefore, it needs to be treated if it will be used as a construction base. This study aims to determine the effect of adding Na₂CO₃ (sodium carbonate) on the consistency and shear strength in clay soils. This study was conducted by preparing a mixture of various concentrations of Na₂CO₃, namely 0.4%, 0.6%, 0.8% and 1.0%, which were added to clay soil samples, which is added to clay soil samples. Consistency testing using the Atterberg limit test (Casagrande Stone). The results showed that the addition of Na₂CO₃ had an influence on the consistency of clay soil. In the shear strength test, there are values of cohesion, shear angle and shear strength, where the percentage of mixture increases. So that in this test the optimum shear strength value can be obtained on a mixture of 1% Na₂CO₃soil.
