Abstract

Sebagian besar negara-negara di Afrika mengandalkan pertanian dan vegetasi sebagai sumber utama kehidupan mereka, dan Oodweyne, sebuah desa di Somaliland, tidak berbeda. Pertanian dan vegetasi dianggap menjadi prioritas utama distrik ini. Kedua hal tersebut sangat dipengaruhi oleh air, dan saat ini tidak ada cukup air yang tersedia untuk mendukung pertumbuhannya. Desa ini sudah dua tahun terakhir tidak mengalami hujan, dan sedang mengalami tekanan yang signifikan akibat kekeringan. Pasokan air baru dan tahan lama sangat dibutuhkan. Untuk saat ini, fokus utamanya adalah mendapatkan air untuk irigasi tanaman (pertanian). Oleh karena itu, proyek ini mengusulkan ide untuk mengairi lahan pertanian dengan menggunakan air dari kondensasi (pengumpulan air). Ide kedua adalah mengumpulkan air hujan di desa yang mungkin akan datang secara tak terduga di masa depan menggunakan sistem drainase, lalu menyimpannya di waduk penyimpanan air yang berada di ujung sistem drainase tersebut. Oleh karena itu, proyek ini akan berfokus pada tiga proyek tersebut, yaitu sistem irigasi, sistem drainase, dan penyimpanan air. Untuk sistem irigasi, proyek ini memiliki lahan seluas 55 hektar yang tersedia untuk tanaman. Lahan tersebut terletak di wilayah barat daya desa. Metode irigasi tetes di bawah permukaan (sub-surface drip irrigation/SDI) telah dipilih untuk proyek ini. Metode ini merupakan metode irigasi yang paling efektif dan akurat, yang dapat menghemat air hingga 60% lebih banyak daripada metode konvensional. Keputusan telah diambil untuk membuat saluran drainase dan meletakkannya di tengah jalan di setiap jalan di desa. Diasumsikan bahwa curah hujan total dalam sebulan adalah sekitar 150 mm. Bagian keseluruhan dari sistem drainase ini akan memiliki 132 saluran di seluruh desa. Penyimpanan air akan berada di wilayah tenggara desa, ditentukan oleh topografi desa. Volume akhir penyimpanan adalah 28500 m3, dan itu memenuhi jumlah air yang dibutuhkan untuk sistem irigasi selama sebulan.

Most of African nations rely on agriculture and vegetation as their primary sources of sustenance, and Oodweyne, a village in Somaliland, is no different. Agriculture and vegetation are thought to be the district's top priorities. Both of those things are greatly influenced by water, and there is now not enough water available to support their growth. The village has not had any rain for the last 2 years. The village is experiencing significant strain due to the drought, and a new, long-lasting water supply is desperately needed. For now, the focus is to have water for irrigating crops (agriculture). So, the project came up with the idea of irrigating agricultural land with water from the condensation plant (water harvesting). The second idea is to collect the rainwater in the village that hopefully will come unexpectedly in the future using the drainage system, then reserve it for water storage located at the end of the drainage system. Therefore, this project will focus on those three projects, which are the irrigation system, drainage system, and water storage. For the irrigation system, this project has 55 hectares available for crops. It is located in the southwest area of the village. sub-surface drip irrigation (SDI) has been chosen to be the method for this project. It is the most effective and precise irrigation method, that could save water up to 60% more than the conventional method. The decision was made to make a drainage channel and place it in the middle of the road on every road in the village. It is assumed that the total precipitation in a month is around 150 mm. For the whole drainage system part, this project will have 132 channels all around the village. The water storage will be located in the southeast area of the village, defined by the topography of the village. The final volume of storage is 28500 m3, and it fulfils the amount of water needed for the irrigation system for a month.
