Abstract

This study aims to understand the relationship between the Climate Village Program (ProKlim) success rate and climate change adaptation and mitigation actions in Paser Regency. The results of the analysis showed that simultaneously climate change adaptation actions had a real effect on the success rate of ProKlim in Paser Regency by 81.45% with a significance level of 0.00054 (less than α = 0.05), while climate change mitigation actions have a real effect on the success rate of ProKlim in Paser Regency by 83.66% with a significance level of 0.0052 (less than α = 0.05). Meanwhile, the relationship of adaptation actions to the success rate of the ProKlim in Paser Regency is partially influenced by the efforts of control of climate change-related diseases with a significant level of 0.0305 (less than α=0.05). Meanwhile, climate change mitigation actions, it is partially influenced by low-emission agricultural cultivation efforts with a significant level of 0.0305 (less than α=0.05). Thus,  the efforts to achieve the success of ProKlim cannot be done partially but must be carried out comprehensively because the impact of climate change has been felt in all aspects so it is necessary to apply all variables of climate change adaptation and mitigation sustainably.ABSTRAKPenelitian ini bertujuan untuk memahami hubungan tingkat keberhasilan Program Desa Iklim (ProKlim) dengan aksi adaptasi dan mitigasi perubahan iklim di Kabupaten Paser. Hasil analisis menunjukkan bahwa secara simultan aksi adaptasi perubahan iklim berpengaruh nyata terhadap tingkat keberhasilan ProKlim di Kabupaten Paser sebesar 81,45% dengan tingkat signifikansi 0,00054 (kurang dari α = 0,05), sedangkan aksi mitigasi perubahan iklim mempunyai pengaruh nyata terhadap keberhasilan ProKlim di Kabupaten Paser. berpengaruh terhadap tingkat keberhasilan ProKlim di Kabupaten Paser sebesar 83,66% dengan tingkat signifikansi 0,0052 (kurang dari α = 0,05). Sedangkan hubungan tindakan adaptasi terhadap tingkat keberhasilan ProKlim di Kabupaten Paser sebagian dipengaruhi oleh upaya pengendalian penyakit terkait perubahan iklim dengan tingkat signifikansi sebesar 0,0305 (kurang dari α=0,05). Sedangkan tindakan mitigasi perubahan iklim, sebagian dipengaruhi oleh upaya budidaya pertanian rendah emisi dengan tingkat signifikan sebesar 0,0305 (kurang dari α=0,05). Dengan demikian, upaya untuk mencapai keberhasilan ProKlim tidak dapat dilakukan secara parsial melainkan harus dilakukan secara komprehensif karena dampak perubahan iklim sudah terasa di seluruh aspek sehingga perlu diterapkannya seluruh variabel adaptasi dan mitigasi perubahan iklim secara berkelanjutan.

Abstract

Water and water resources must be maintained by their functions and benefits to meet the needs of all sectors and future generations. One important part of sustainable water resource management that is of considerable interest to the government is irrigation which aims to achieve food security. Food security in Indonesia Development in the field of food security and poverty alleviation in rural areas is one of the leading sectors in the nine national development priority agendas contained in Nawa Cita”. The development of food security in Indonesia faces many complex problems, such as irrigation infrastructures maintenance, regulations, land use change, population, policy implementation, coordination among stakeholders and also budget issues. The method in this study is a qualitative method through the literature review related to the management of water resources for food security in Indonesia. This paper seeks to evaluate the development irrigation policies as part of sustainable water management that supports food security in Indonesia. Literature sources are 5 main regulations, 5 papers and some government reports. To support increased food security, the direction of the Indonesian Government's policy in strengthening food security from the irrigated agricultural sector is realized through a strategy to increase production capacity and improve irrigation network services. The problem of the availability of irrigation water must be addressed quickly by upstream conservation, maximizing capacity through normalization of existing reservoirs, and continuing to build dams to have water storage containers that can accommodate planting season throughout planting. Air dan sumber daya air harus dijaga fungsi dan manfaatnya untuk memenuhi kebutuhan semua sektor dan generasi mendatang. Salah satu bagian penting dari pengelolaan sumber daya air berkelanjutan yang cukup menarik perhatian pemerintah adalah irigasi yang bertujuan untuk mencapai ketahanan pangan. Di Indonesia, pembangunan di bidang ketahanan pangan dan pengentasan kemiskinan di pedesaan merupakan salah satu sektor unggulan dalam sembilan agenda prioritas pembangunan nasional yang tertuang dalam Nawa Cita”. Pembangunan ketahanan pangan di Indonesia menghadapi banyak masalah yang kompleks, seperti pemeliharaan infrastruktur irigasi, regulasi, perubahan penggunaan lahan, kependudukan, implementasi kebijakan, koordinasi antar pemangku kepentingan dan juga masalah anggaran. Metode dalam penelitian ini adalah metode kualitatif melalui studi pustaka terkait pengelolaan sumber daya air untuk ketahanan pangan di Indonesia. Tulisan ini berupaya mengevaluasi kebijakan pembangunan irigasi sebagai bagian dari pengelolaan air berkelanjutan yang mendukung ketahanan pangan di Indonesia. Sumber literatur adalah lima peraturan utama, lima makalah dan beberapa laporan pemerintah. Untuk mendukung peningkatan ketahanan pangan, arah kebijakan Pemerintah Indonesia dalam memperkuat ketahanan pangan dari sektor pertanian beririgasi diwujudkan melalui strategi peningkatan kapasitas produksi dan peningkatan pelayanan jaringan irigasi. Masalah ketersediaan air irigasi harus segera diatasi dengan konservasi di wilayah hulu, memaksimalkan kapasitas melalui normalisasi waduk yang ada, dan terus membangun bendungan untuk memiliki wadah penampung air yang dapat mencukupi kebutuhan pasokan sepanjang musim tanam.

Abstract

The North Coast of Jakarta is a strategic area to support the economy of the DKI Jakarta Province and as a place to live for organisms, one of which is phytoplankton. Phytoplankton is a primary producer in aquatic ecosystems that have an essential role in maintaining aquatic ecosystems and as an indicator of water quality. This study aims to determine the quality of seawater (turbidity, TSS, BOD, Phosphate, and Nitrate) and the diversity of species (H') of phytoplankton in the waters of the North Coast of Jakarta around the reclamation islands C and D from 2006 to 2021. Types of data used in this study is secondary data from Environmental Impact Analysis (ANDAL) documents and reports on the implementation of the Environmental Management Plan and Environmental Monitoring Plan for Reclamation and Development on Islands C and D. Concentrations of turbidity, TSS, BOD, phosphate, and nitrate in coastal waters North of Jakarta around the reclamation islands C and D are fluctuation and several sampling times exceed the quality standard. The species diversity index (H') of phytoplankton in the coastal waters of North Jakarta around the reclamation islands C and D is dominantly included in the criteria for community stability in stable conditions (H 3). Based on the partial correlation test, phosphate with the diversity of phytoplankton species in the waters of the North Coast of Jakarta around reclamation island C and D had a significant relationship (P 0.05).
