Abstract

The community service activity which was carried out in the Panjer Traditional Village, Denpasar aims to help overcome flooding in the Panjer Traditional Village area by installing hundreds of biopore holes. Biopores are small holes made at the surface of the soil with the aim of increasing the soil's absorption of rainwater. This method was first developed by Dr. Kamir R. Brata from the Bogor Agricultural University (IPB) as a solution to overcome the problem of waterlogging and urban flooding. Biopore holes are made using special tools to drill the soil to a certain depth, usually filled with organic matter such as leaves or food scraps. This organic matter will then be broken down by soil microorganisms, creating empty spaces that increase soil porosity. The activity was carried out simultaneously with hundreds of students and lecturers of the Faculty of Engineering and Informatics, Universitas Pendidikan Nasional. There are 14 groups divided into this biopore hole installation activity. The installation locations are spread across several points starting from the Waturenggong Street area to the end of Jalan Tukad Yeh Aya. The main function of biopores is to increase the absorption of groundwater, so that it can help reduce the risk of flooding and waterlogging. In addition, biopores also function to improve soil structure and increase soil fertility by adding organic matter. Another benefit of biopores is that it helps the process of recycling organic waste into compost that is beneficial to plants.

Abstract

Inundation on roads is a common problem in urban areas, the ones at the Palangka Raya City. The existing drainage system at the study area still uses a conventional drainage system and unable to accommodate the inundation. Thus requires for handling by absorbing or temporarily accommodating the inundation before being discharged into the river which is the concept of an eco–drainage system. To determine the design discharge of the drainage channel at the study area, hydrological data processing is analyzed using the TRMM satellite rainfall data due to the limited rainfall data length. From the results of processing the TRMM satellite rainfall data, the design discharge for the Kahayan and Sebangau Drainage Systems are different in each channel. By using a 5-year return period, the smallest design discharge value is 1,097 m3/s and the largest is 59,111 m3/s. From the evaluation results, 11 out of 28 existing channels need to have inundation control. Chosen alternative to inundation control with eco–drainage concept is by rehabilitating channels and making detention ponds. This alternative can reduce inundation by 100%. Genangan air yang muncul di ruas-ruas jalan merupakan suatu permasalahan umum di daerah perkotaan salah satunya pada Kota Palangka Raya. Sistem drainase yang ada pada kawasan ini masih menggunakan sistem drainase konvensional dan belum mampu menampung genangan yang terjadi. Sehingga perlu adanya penanganan dengan cara meresapkan atau menampung sementara genangan sebelum dibuang ke badan sungai yang merupakan konsep dari sistem drainase berwawasan lingkungan. Untuk mengetahui debit rancangan pada saluran drainase di lokasi studi, dilakukan pengolahan data hidrologi menggunakan bantuan data hujan satelit TRMM karena keterbatasan panjang data hujan di lapangan. Dari hasil pengolahan data hujan satelit TRMM, didapatkan debit rancangan pada Sistem Drainase Kahayan dan Sebangau yang berbeda pada tiap saluran. Dengan menggunakan kala ulang 5 tahun, didapatkan nilai debit banjir rancangan terkecil 1,097 m3/dt dan terbesar 59,111 m3/dt. Dari hasil evaluasi didapatkan 11 dari 28 saluran yang ada perlu dilakukan penanganan genangan. Alternatif penanggulangan genangan dengan konsep drainase berwawasan lingkungan yang dipilih yaitu dengan merehabilitasi saluran dan pembuatan kolam detensi. Alternatif tersebut dapat mereduksi genangan sebesar 100%.
