Abstract

Kabupaten Bojonegoro merupakan salah satu kabupaten yang memiliki perkembangan yang pesat pada pembangunan daerah maupun populasi penduduk sehingga menjadikan perubahan tata guna lahan yang berdampak berkurangnya daerah resapan air. Wilayah Timur Kota Bojonogoro terdapat Afvoer Sukorejo yang memiliki fungsi sebagai saluran drainase di Kota Bojonegoro bagian timur. Aliran saluran ini berakhir pada pertemuan dengan kali Loro dan Bersama-sama menuju Sungai Bengawan Solo melalui sodetan sungai sampai pintu air Semanding dan mengalir secara gravitasi menuju pintu air Kalirejo. Wilayah ini sering terjadi genangan banjir disaat musim penghujan melanda. Oleh karena itu, penelitian ini bertujuan untuk bertujuan untuk mengetahui kondisi penampang saluran yang ada (existing) terhadap besarnya debit banjir rencana periode ulang 10 tahun. Analisis yang dilakukan ialah analisis hidrologi dengan melakukan perhitungan debit rencana periode ulang dan analisis hidrolika penampang dengan menggunakan software HEC-RAS (Hidrologic Engineering Center – River Analysis System). Data yang diperlukan berupa data primer yaitu kondisi existing saluran, tata guna lahan, juga arah aliran dan berupa data sekunder yaitu data curah hujan, peta catchment area serta peta tata guna lahan. Hasil analisis didapatkan bahwa kapasiitas existing saluran Afvoer Sukorejo sampai dengan Pintu Air Semanding dalam menerima debit banjir rencana periode 10 tahun terdapat 2 kondisi yaitu tidak aman dan aman. Kondisi tidak aman hampir terjadi pada banyak saluran yaitu meliputi : Afvoer Sukorejo, Kali Loro Segmen 1, 2 dan 3, dan Sodetan Semanding-Kalirejo dengan kedalaman luapan bervariasi. Sedangkan kondisi aman hanya terjadi pada saluran Sodetan Semanding segmen 1 dan 2

Abstract

Watershed health is a crucial indicator of the watershed's ecological function and its capacity to provide sustainable environmental services. Environmental degradation due to anthropogenic activities such as land conversion in the Pacal watershed, Bojonegoro, has triggered an increase in the frequency of floods and droughts, indicating a critical decline in the watershed's hydrological function. This study aims to quantitatively evaluate the health level of the Pacal watershed through the analysis of two hydrological parameters River Regime Coefficient (KRS) and Water Storage Coefficient (KSA). The analysis results indicate that the hydrological condition of the Pacal Watershed falls into the poor category. The average KRS value during the 2013-2022 period was 282, classified as Very High. This very high KRS value indicates extreme discharge fluctuations and significant river flow instability, which have a high potential to trigger floods and droughts. Meanwhile, the average KSA value obtained was 0.057, classified as Poor. A very low KSA value indicates very limited infiltration and groundwater storage capacity, resulting in most rainwater becoming rapid surface runoff and minimal base flow during the dry season. Poor KRS and KSA values ​​indicate that the water regulation function of the Pacal Watershed has been critically degraded.

Abstract

The need for clean water, which is still mostly still supplied by groundwater, if it is used continuously, can experience a clean water crisis, but on the contrary, surface water during the rainy season is very abundant so it needs to be utilized. The use of excess water during the rainy season can be used for various purposes when water is needed, especially supplies when experiencing a water crisis in the dry season. Rainwater is considered cheap in its use because rain must fall in every place so that it can be used directly both without and with the treatment process. The use of rainwater as a source of clean water is by Rainwater Harvesting technique. The purpose and benefits of the service carried out are to provide understanding to the PKK Mobilization Team related to Rainwater Harvesting (RWH) so that it is expected to be able to become a Village Initiator on a household scale to move towards a Clean Water Independent Village. The method is carried out by socialization using interactive material presentations and then discussions at the end of the session. A total of 91 participants from 26 villages who participated were able to receive socialization materials well and a detailed understanding which is evident from the enthusiasm of the participants in the discussion and question and answer sessions provided in the forum. This understanding can be a provision for the PKK mobilization team of each village as a Village Initiator on a household scale to realize an independent village with clean water.
