Abstract

Muara Enim road segment SP. Sugihwaras very potential to occur landslide based on its location which is on the edge of the river. Recorded by the National Road Implementation Institute (BBPJN) III has been a slope grid in 2014. Slope improvement efforts undertaken by the Ministry of Public Works using a combination of gabion not too successfully overcome the problem. In addition to the strength element of a construction work, the cost and timing of the implementation are also important considerations in planning. Slope at 173 + 535 - Km 173 + 705 along 170 m using soil nailing planned three nails with 19 mmnail diameter and angular slope of 20° with variation of nail length, nail installation spacing, safety factor (SF) and estimated working time to the cost. Using the SPSS.16.0 program, the variations are modeled by nine samples as multiple linear regression equations. Based on the SPSS output, then tested the classical assumption and feasibility test model which produced the model: Cost (million) = - 3159,475 - 54,097 length - 1354,256 distance + 5188,127 SF + 26,483 time. The Budget Plan (RAB) covers preparatory work, drainage system, soil nailing, and shotcrete. An efficient cost estimate of 8 m length nail, 1.5m installation distance, 1.5 safety factor and 64-day working time resulted in a cost of Rp. 3.853.485.500,00 (Three billion eight hundred fifty three million four hundred eighty five thousand rupiah).

Abstract

A typical relatively steep slope makes the Lb. Selasih – Bts. Kota Padang KM.29+650 experienced a landslide in 2017. So, it is necessary to strengthen the slope to overcome the landslide. Alternative slope reinforcement used is reinforcement using cantilever retaining walls or geotextiles. Slope stability analysis before and after were analyzed using the Slope/W program. The output produced by Slope/W program is the value of the safety factor. The safety factor value for the state of the original slope is 1.100. It shows that the slope in the original condition is unstable and vulnerable to landslide hazards. The retaining wall has a height of 11 m and a base plate width of 8 m. The results of the analysis showed that the cantilever retaining wall securely with stands shear, rolling, and bearing capacity of the subgrade with a safety factor value of 1.620; 1.550; 2.160, while geotextile reinforcement has a height of 16 m and an ultimate tensile strength of 200 kN / m. The results of the analysis showed that the reinforcement of the geotextile safely sliding, stability, and bearing capacity of the subgrade with a safety factor value of 1.600; 2.330; 2.860. Both of these reinforcements are safe to stabilize the slope by increasing the value of the slope safety factor by 2.235 for strengthening the cantilevered retaining wall and 2.279 for strengthening the geotextile.

Abstract

There is a potential overflow of a river during rain, resulting in water levels raised beyond normal water levels in the Sentiong Underpass Area, Jakarta in which is one of the strategic locations in Central Jakarta. To guarantee and maximize water flow in the Sentiong Underpass area, a water discharge regulatory system was created to be the form of underground wall structures equipped with pump houses. This wall structure is made of reinforced concrete structures underground at ± 3 m depth. This research aims to evaluate and analyze the underground wall capacity with reference to principles designed by SNI 2847-2013 and SNI 1727-2013. Analysis of data used based on field data including soil test parameters and vehicle traffic. Structural analysis which used is Computer Program (STAADPro), then based on the data obtained from the results of analysis and evaluation can be determined magnitude of displacement and dimensions of the reinforcement. The wall structure in Sentiong Area, Jakarta was planned to use K-300 concrete as high as 3 m underground, 40 cm of wall thickness, bottom floor thickness 40 cm, and upper floor thickness 20 cm. The total length of this underground wall structure was planned 32 m. Based on the results of the analysis, it was found that displacement and capacity structure qualified safely with design steel reinforcement diameters of D13 mm and D16 mm.

Abstract

Flood control is one of the prevention methods which involves various engineering sciences and is unique. One of structural flood control methods is retention basin with the goal of containing a certain storm event flow volume and obtaining a specific peak flow reduction. This paper’s objective is to describe how to assess the performance of retention basin physical components quantitatively on seven retention basins in Palembang City. The reference and the parameter used in this research are referred to Drainage Systems Assessment Design (Vadlon, 2011) that is based on Standard Procedure of Retention Basins and Polders Construction according to Public Works Ministry of Cipta Karya Directorate General and the Regulation of Public Work Ministry No.32/PRT/M/2007. The result of the assessment is that there are three retention basins which are in good condition, namely Kambang Iwak Besak (63,9%), Simpang Polda (60,34%), and Kambang Iwak Kecil (56,8%); meanwhile the other four basins are in bad conditions, namely RS. Siti Khodijah (43,01%), Palembang Icon (41,93%), Kemang Manis (7,03%), and Brimob (0,94%). Therefore, the assessment of the retention basins towards its effectiveness on flood controlling and handling priority level is done by hydraulic modeling simulations and GIS. 4. Based on the inundation priority assessment of simulated flood depth and duration, it can be inferred that the retention basin of Kambang Iwak Besak, Kambang Iwak Kecik, Palembang Icon, RS Siti Khodijah, and Kemang Manis have low priority handling level. Meanwhile, Brimob and Simpang Polda retention basins have high priority handling level.

Abstract

Efforts to change people's behaviors to support the improvement of health status are carried out through the Clean and healthy living behavior (CHLB) development program. Although this program has been implemented by the Ministry of Health in Indonesia since 1996, CHLB implementation has not run optimally. Evaluation of CHLB development's success is carried out by looking at CHLB indicators, one of which is in the school setting. CHLB at school is an activity to empower students, teachers, and the school community to adopt a healthy lifestyle to create healthy schools. This study aims to increase the students' knowledge, attitudes, and actions regarding CHLB in Madrasah Diniyyah, Al Islam Educational Institution, Talang Aur Village, Ogan Ilir Regency, South Sumatra Province.The study uses action research. This activity is carried out by providing communication, information, and education (KIE) regarding CHLB. In addition, we offer knowledge tests about CHLB and demonstrations by practicing how to wash hands correctly and adequately using clean water and soap to increase students' understanding of CHLB activities. This study emphasizes the importance of socializing clean and healthy life early through integrating learning programs in schools. The results showed an increase in the target audience's knowledge, attitudes, and actions about CHLB. The benefits of CHLB in schools include creating a clean and healthy environment, improving the teaching, and learning process, and making students, teachers, and the school environment healthy.

Abstract

Abstrak Pembangunan kolam retensi Arafuru belum mampu mengurangi frekuensi terjadinya banjir secara optimal karena Jalan Arafuru masih termasuk dalam lokasi titik banjir yang terdapat pada DAS Buah dengan ketinggian banjir antara 50-100 cm dengan durasi 24 jam. Kolam tambahan yang akan dibangun direncanakan seluas 5950 m2 untuk menampung kelebihan kapasitas kolam retensi eksisting. Optimalisasi kapasitas tampung kolam retensi Arafuru dapat dilakukan dengan mengkoneksikan outlet kolam retensi eksisting dengan inlet kolam retensi baru yang memiliki luasan 5950 m2 dengan kedalaman minimal 3 m untuk memenuhi daerah layanan/catchment area dengan luasan ±96,17 Ha. Pendugaan debit puncak limpasan permukaan dilakukan dengan metode SCS-CN dan didapatkan tinggi elevasi muka air maksimum inflow sebesar 11,4 m3/s terjadi pada menit ke 60, sedangkan elevasi puncak yaitu 2,7 m. Simulasi reduksi debit banjir dilakukan dengan software HEC-HMS, didapatkan bahwa penambahan kolam retensi dapat mengurangi debit inflow puncak dari 11,4 m3/s menjadi 7,1 m3/s atau sebesar 37,72%. Kata Kunci: Kolam retensi, analisa hidrologi, analisa spasial, pengendalian banjir  Abstract The construction of Arafuru retention basin has not been able to optimally reduce the frequency of flooding since Jalan Arafuru district is still included as one of the flood points within Buah Watershed with flood depths between 50-100 cm and duration of 24 hours. The additional basin is designed to be 5950 m2 in accordance with the area of land that has been acquired to accommodate the over capacity of the existing retention basin. The optimization of Arafuru retention basin’s capacity can be done by connecting outlet from existing basin to the inlet of the new basin. Retention basin of 5950 m2 with a minimum depth of 3 meters is expected to accommodate runoff from ± 96,17 ha catchment area. The estimation of the peak runoff discharge was carried out using the SCS-CN method and the maximum inflow water level elevation was 11,4 m3 / s occurring in the 60th minute, while the peak elevation was 2,7 m. The simulation of flood discharge reduction using HEC-HMS resulted that the addition of a retention basin could reduce the peak inflow from 11,4 m3 / s to 7,1 m3 / s or as much as 37,72%. Keywords: retention basin, hydrological analyses, spatial analyses, flood control
