Latar belakang: Tujuan tulisan ini adalah mengkaji dan menganalisis strategi pemerintah dalam menjaga dan mengelola sumber daya air dalam mencapai ketersediaan air bersih di Indonesia, mengingat peristiwa perubahan iklim juga dapat meningkatkan krisis air. Pemanfaatan air secara terus menerus dan terbatasnya jumlah air yang dapat dieksplorasi dan dikonsumsi dipengaruhi oleh jumlah penduduk yang menyebabkan meningkatnya kebutuhan air. Tulisan ini meninjau secara filosofis dan konseptual yang akan menggabungkan perspektif dari langkah-langkah praktis di tingkat dasar seperti strategi perlindungan berupa kebijakan yang telah dibuat seperti Regulasi, Pengelolaan (dalam pengelolaan akan dikaji sejauh mana campur tangan manusia/pemerintah dalam menjaga kesehatan Ekosistem Lingkungan, termasuk sumber air dan sejauh mana pemanfaatannya, kemudian metode apa yang dipakai dan disepakati oleh pemangku kepentingan dalam memastikan kebutuhan air sehingga dapat terpenuhi), evaluasi dan usaha menjaga/melindungi sumber air.Metode: Metode penelitian ini menggunakan analisis kualitatif dengan pengumpulan data yang dilakukan melalui studi pustaka dengan mengumpulkan berbagai bahan dari buku, jurnal, hasil penelitian, dan media (berita) yang kemudian dianalisis menggunakan model triangulasi yang terdiri dari reduksi data, penyajian data, dan penarikan kesimpulan.Hasil: Pada pelaksanaannya, pemerintah telah melakukan pengelolaan ketersediaan air secara kuantitatif dan kualitatif dengan memperhatikan dan menentukan program prioritas dan kegiatan dalam pemanfaatan air. Hal tersebut dilakukan dengan pemantauan air sungai secara manual dan otomatis secara kontinu. Upaya selanjutnya dalam pengelolaan ialah pelaksanaan konservasi air, perlindungan pelaksanaan pengelolaan secara teknis dan nonteknis berupa kebijakan dalam pengelolaan sumber daya air seperti yang telah diatur dalam Undang-Undang No. 17 Tahun 2019 tentang Sumber daya air. Undang-undang ini memuat kebijakan yang secara tegas mengatur tentang sumber air di Indonesia, termasuk evaluasi berupa upaya pengendalian yang didasarkan dari hasil suatu penilaian bahaya dan risiko terhadap air tanah (Groundwater Hazard and Risk Assessment).Simpulan: Secara konsep, strategi yang dupayakan telah mengarah pada terbebasnya Indonesia dari krisis air di masa sekarang dan masa mendatang sesuai dengan perlindungan/produk yang mengatur. Namun pada Pelaksanaan Pengelolaan, konservasi dilakukan secara parsial atau sebagian. Pengelolaan air tanah belum dilaksanakan secara arif dan komprehensif. Tidak adanya pendekatan yang berkelanjutan dan perubahan paradigma oleh pihak yang terlibat dalam pengelolaan ketersediaan air menjadi pemicu tidak terjalinnya koordinasi yang baik antar pemangku kepentingan. Penilaian risiko belum begitu signifikan karena tidak ada unsur kontinuitas dalam pelaksanaan pengelolaan dan pemanfaatan, baik oleh masyarakat maupun kebijakan yang mengatur. ABSTRACT Background: This paper aims to examine and analyze the government’s strategy in maintaining and managing water resources in ensuring clean water availability in Indonesia, considering that climate change can also increase the water crisis. The continuous use of water and the limited amount of water that can be explored and consumed is influenced by the population, which causes an increase in water demand. This paper reviews philosophically and conceptually by combining the perspectives of practical steps at the basic level such as protection strategies in the form of policies that have been made such as regulation, management (in management, the extent of human/government intervention in maintaining the health of environmental ecosystems, including water sources and the extent to which they are used, then what methods are used and agreed upon by stakeholders in ensuring that water needs can be met), evaluation, and efforts to maintain/protect water sources.Methods: The research method used qualitative analysis with data collection carried out through library research by collecting various materials from books, journals, research results, and media (news). The data were then analyzed using a triangulation model consisting of data reduction, data presentation, and conclusion.Results: In practice, the government has carried out quantitative and qualitative management of water availability by considering and determining priority programs and activities in water utilization. This is done by monitoring river water manually and automatically continuously. The next effort in management is the implementation of water conservation, protection of the implementation of technical and non-technical management in the form of policies in the management of water resources as regulated in Law No. 17 of 2019 concerning Water Resources. This law contains policies that strictly regulate water resources in Indonesia, including evaluation of control measures based on the results of an assessment of hazards and risks to groundwater (Groundwater Hazard and Risk Assessment). Conclusion: Conceptually, the strategy sought has led to Indonesia’s freedom from water crises in the present and the future by the protection/products that regulate it. Still, it is carried out partially in the implementation of conservation management. Groundwater management has not been implemented wisely and comprehensively, and there is no appropriate approach. Then the paradigm shift by the parties involved in water availability is the trigger for the lack of good coordination between stakeholders. The risk assessment is not highly significant because there is no element of continuity in implementing management and utilization by both the community and the policies that regulate it.

Road drainage function as important part that can control a large rainfall that caused puddles that often disturb the comfort of all community activities on the road. Condition of the drainage channel on the road Kebon Pala area, East Jakarta are not qualified due to mistake planning and lack of maintenance. Hence, it is necessary to evaluate the capacity of drainage channel on Road Perindustrian. The purpose of this study is to find the maximum amount of water flow that can be accommodated by drainage channels. Rain intensity was calculated using the Mononobe method, as well as the flow rate is calculated using the Rational method. The existing capacity of drainage dimensions are measured directly in the the field using Manning method for calculating flow velocity. The results obtain Q2yrs = 1.27mm/s, Q5yrs = 1.67mm/s, Q10yrs = 1.84mm/s, while Q channel 0.24mm/s. Thus, it can be concluded that capacity of road drainage channel is lower than Q rain that can not accommodate the existing rain flow.

Based on the Area Sample Framework (KSA) results, rice production in West Sumatra has decreased by 6 per cent from 2019 to 2020. This shows that rice farming still faces various risks affecting its production and productivity. As the main farming actors, farmers receive the most significant impact and risk due to climate-related disasters. Farmers must bear risks in production, price, market, financial, technological, social, legal, and human risks. Production risk occurs due to yield fluctuations due to various factors that are difficult to predict (climate change, extreme weather, floods, droughts, and pest attacks). This study aims to (1) identify the risks of rice farming in Padang City and (2) measure the magnitude of rice farming risks faced by farmers in Padang City. Data were collected using questionnaires from 30 farmers. The results showed that the risks faced by farmers were the risk of land management, the risk of flooding, risk of drought and the risk of pest and disease attacks. The risk faced by farmers in their farming business as a whole is low. The risk of flooding and drought has a large percentage of greater risk. The flood risk mitigation carried out by farmers, in general, is to let their land be flooded, while farmers carry out drought risk management by looking for water sources.
