Abstract

The influence of land cover and intensity is one of the factors that influence the value of surface flow coefficient (C). The coefficient value will affect the surface flow occurs during peak discharge. In this research, calculate surface coefficient (C) with variation intensity 40 mm/h, 50 mm/h, 60 mm/h, 70 mm/h for land cover paving block (brick pattern and matting pattern), grass block , mini elephant grass, sand and concrete pavement. This test is expected to be the solution in choosing the right type of land cover as a substitute for concrete pavement in the parking lot, park, or home or office yard. The implementation methodology was carried out by laboratory testing with rainfall simulator, 4 cm high base layer of sand and various land cover around 4 cm. The test that carried out in this study include filter analysis, rain intensity and surface coefficient value (C) testing. Testing value of coefficient including the test using rational formulas and testing by definition (Scwab, 1981 and Mc Guen, 1989). The result of this research obtained coefficient of land cover paving block pattern of stacking brick 0,857-0,891, in land cover paving block matting pattern 0,825-0,856, while at grass block 0,677-0,765. The coefficient of surface flow (C) for concrete pavement cover is 0.961-0,997, mini elephant grass cover is 0,483-0,538, while without land cover is 0,559-0,639. The value of surface flow coefficient (C) is getting bigger with increased rain intensity and land cover that has fewer gaps, in this case there is a significant difference in the paving block and grass block.

Abstract

The increment of urban infrastructure development causes the green land as a catchment area changes into watertight land cover, so the surface runoff increases. When the surface runoff more than the infiltration, its causes floods. One of the solutions is reduce the quantity of watertight land by using the eco-friendly land cover. Besides land cover, land slope is one of the factors affecting amount of surface flow. Therefore, this study was conducted to determine the effect of land cover use and slope relation to surface flow discharge with rain intensity 70 mm / hour. This research was conducted in laboratory using rainfall simulator with area 2 x 1 m and slope variation 0%, 1%, 2%, 3%. Types of land cover used in this research are paving block (stretcher and basketwave pattern), grass block, grass (Pennisetum purpureum schamach), concrete pavement and sand (as land without cover). The results of this study indicate the use of concrete pavement to produce surface flow discharge value ranged from 2.66 to 3.22 liters / minute, paving block of stretcherbond ranged from 2.43 to 3.0 liters / minute, paving block basketwave ranged from 2.17 to 2.72 liters / minute, grass block ranged from 1.99 to 2.59 liters / minute. Grass produced surface flow discharge ranging from 1.40 to 2.12 liters / minute and sand as land without cover ranged from 1.48 to 2.29 liters / minute. The land slope variation is very influential on the amount of surface runoff discharge. The steeper land, make the surface runoff discharge increase.

Abstract

Daerah dataran tinggi biasanya rentan terhadap terjadinya erosi yang disebabkan oleh tingginya curah hujan, kondisi kemiringan lahan, struktur tanah yang tidak komposit, dan praktek pengolahan lahan yang tidak sesuai. Besarnya curah hujan pada waktu yang lama akan menyebabkan tergerusnya tanah akibat energi kenetik hujan yang bekerja di atas permukaan tanah tersebut. Tujuan penelitian untuk menghitung indek erosivitas serta mengetahui besarnya erosi pada Sub DAS Lematang bagian hulu. Dalam penelitian digunakan model RUSLE (Revised Universal soil Loss Equation), merupakan perhitungan besarnya erosi, disebabkan oleh besarnya energi kinetik yang bekerja pada daerah tersebut. Hasil penelitian menunjukkan bahwa nilai erosi maksimum pada sub DAS Lematang Hulu adalah sebesar 5,904146 Ton/Ha/Tahun, nilai erosi minimum 4,168 Ton/Ha/Tahun. Sementara nilai erosi rata-rata adalah 2.904,157 Ton/Ha/Tahun. Secara umum pada wilayah penelitian terjadi erosi rata-rata sebesar 4,168 Ton/Ha/Tahun.

Abstract

Penyebab Banjir terbesar yang terjadi di kota Palembang khususnya yang terjadi di kawasan perumahan adalah karena banyaknya lahan rawa yang direklamasi menjadi daerah permukiman. Salah satu Perumahan sering terjadi banjir di kota Palembang adalah perumahan Bukit Sejahtera. Untuk itu diperlukan analisis tingkat bahaya banjir, dan tingkat kerentanan pada perumahan Bukit Sejahtera, serta analisis tingkat risiko akibat banjir pada perumahan Bukit Sejahtera. Untuk menganalisis tingkat bahaya, tingkat kerentanan, dan tingkat risiko dilakukan dengan cara pemetaan dengan menggunakan aplikasi program ILWIS. Indeks kerentanan infrastruktur (IVI) ditentukan berdasarkan indikator-indikator kerentanan seperti luas bangunan, jumlah penghuni, jenis pekerjaan, kondisi jalan, dan keadaan drainase. Dari hasil running didapatkan luas daerah yang mempunyai potensi bahaya banjir adalah 47.30 % dari luas perumahan Bukit Sejahtera, dan didapatkan IVI rumah maksimum 0.50 dan minimum 0.10, dimana jumlah rumah moderate vulnerability 593, dan low vulnerability 392 rumah. Analisis akhir pada kajian kerentanan adalah analisa risiko dengan melakukan overlay antara bahaya dan tingkat kerentanan infrastruktur perumahan. Dari hasil analisis risiko diketahui bahwa terdapat 592 rumah yang tidak ada risiko, 138 rumah tingkat risiko rendah, dan 255 rumah dengan tingkat risiko yang sedang. Dalam penelitian ini tidak didapatkan rumah yang memiliki tingkat risiko yang tinggi. Kata kunci : banjir, bahaya, kerentanan, indeks kerentanan infrastruktur (IVI), ILWIS.

Yuono AL, Putranto DDA, Sarino S. 2019. Spatial analysis of environmental and hydrological conditions upper komering sub basin relationship with water availability. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang 4-5 September 2019. pp. 430-436. Palembang: Unsri Press.Potential water resources in the Komering sub-basin (645.49 m3 / sec), in March (Putranto Dinar DA et al, 2015), should be able to increase national agricultural production in South Sumatra. This study aims to analyze spatially the decreasing availability of water in the Komering sub-basin, where the mainstay discharge in August - September, only 43.08 m3/sec. To analyze the reduced mainstay discharge of the Komering sub-basin, due to poor land use practices in the upstream area and the effects of climate variability, it can be analyzed by the Mock method (1978), by analyzing land cover conditions, the value of rain variability, and the amount of evapotranspiration and validation of direct measurements river discharge. Changes in land use for the upper Komering sub-basin, which are used mostly by the population as community plantation areas, have increased the critical condition of the upper Komering sub-basin by 2,517,560 Km2, or about 65.66% of the total upper Komering sub-basin. From the measurement of debit data at the Perjaya weir in the last fifteen years (2005-2019) the biggest mainstay debit value for 2 weeks to two months in April was 241.67 m3/sec, while the smallest mainstay discharge occurred in the first 2 weeks of October at 54,69 m3/sec. A large enough difference between the largest and smallest mainstay discharge, it is necessary to think of a way so that the availability of water is always maintained throughout the year (the mainstay discharge difference between the rainy season and the dry season so that it is not so extreme). Some ways that can be done to maintain water availability include by making water reservoirs during the rainy season, such as reservoirs and reservoirs, or increasing storage in the soil by reforestation and harvesting methode.Keywords: discharge, harvesting, land-use change, resources, spatial

Abstract

Work accidents in the construction industry are practically unavoidable, however they can be minimized. The aim of carrying out this community service is to socialize the importance of introducing occupational safety and health (K3) to protect and ensure the safety of every worker. Apart from that, it is also to increase safety and health awareness for workers in the construction projects and to increase awareness of the use of personal protective equipment for workers. Moreover, it is also to provide management recommendations for the layout of construction equipment and materials so as to create a safe working environment. The results showed that there was a significant increase between before the training and after training to the members for REI of South Sumatra. After the post-test was conducted in class, the community service activities was also integrated with lecture activities by inviting students to get involved in the construction projects.
