Abstract

Kekeringan adalah sebuah bencana alam dengan proses menjalar yang tidak nampak namun dapat teridentifikasi lewat dampaknya terhadap aspek kehidupan manusia. Berdasarkan studi terkini IPCC, bencana alam hidro-meterologi seperti banjir ataupun kekeringan akan mengalami intensifikasi, serta peningkatan dampak risikonya. Hal ini juga semakin tergambar dengan beberapa kejadian kekeringan akibat fenomena El-nino seperti pada tahun 2015-2016 yang dikategorikan kuat. Kejadian ini berdampak sangat parah terhadap aspek pertanian, dan juga perekonomian hingga kesejahteraan penduduk dunia, terkhususnya Indonesia di mana pertanian adalah komoditas utamanya. Oleh karena itu, studi ini bertujuan untuk mengukur seberapa parah kondisi kekeringan yang terjadi akibat fenomena alam El-nino di Indonesia pada tahun 2023 dengan Indeks Kekeringan SPI dan membuat peta sebaran kekeringan pada wilayah tertinjau, sehingga dapat diharapkan menjadi langkah awal mitigasi bencana dampak kekeringan yang terjadi. Metode penelitian yang digunakan adalah perhitungan kuantitatif Indeks Kekeringan SPI, yang diolah menggunakan pengukuran data hujan bulanan berbasis satelit, yaitu GPM 3IMERGMV07 selama 23 tahun (2001-2023) di Pulau Jawa. Pemetaan sebaran wilayah yang terdampak kekeringan dibuat berdasarkan hasil Indeks Kekeringan SPI, dengan menggunakan Metode IDW pada ArcGIS. Hasil analisis dari studi ini menunjukkan bahwa derajat keparahan kekeringan yang terjadi di Pulau Jawa rata-rata akibat fenomena El-nino tahun 2023 adalah -0,84 ± 0,28, selain itu daerah yang mengalami dampak kekeringan paling parah berdasarkan pengukuran indeks ini adalah daerah selatan Pulau Jawa. Hasil ini juga didukung dengan penilaian durasi kekeringan SPI, bahwa rata-rata daerah mengalami kekeringan selama 5 bulan, pada akhir tahun 2023.

Abstract

Gajah Mungkur reservoir is one of the largest multipurpose reservoirs in Java with 100 years of useful life. The purpose of the Gajah Mungkur Reservoir is not only as a flood control, but also for other needs such as hydropower, irrigation and raw water. The construction of the Wosusokas is to objectify the purpose of the reservoir for the distribution of raw water to several regions, namely Gajah Mungkur, Sukoharjo, Solo, and Karanganyar. The purpose of this study was to determine the reliability of the reservoir’s use for raw water with the Wosusokas transmission pipeline network. The method is to simulate a simple operating pattern at the Gajah Mungkur Reservoir using the Standard Operating Rule (SOR) with the target release for irrigation water and raw water. The research findings indicate that more than 70% of the actual release for meeting the needs of irrigation and fulfilling raw water supply is the value of the target release for meeting the needs of irrigation and fulfilling raw water supply. The calculation results also show the percentage of reliability for raw water in 2017 was 100%, while the percentage of reliability in 2018 was 45,833%, and the percentage of reliability from January 2019 to July 2019 was 76,923%.

Abstract

Water use needs to be balanced with efficient management efforts so that quality and quantity are maintained along with population growth. One of the efforts that can support the maintenance of water quality and quantity is water conservation. Therefore, the role of women as the dominating party in water use and control is important in efforts to improve water conservation. This research uses Regression Analysis with 469 respondents, with the criteria that respondents are women over 16 years old and domiciled in the Jabodetabek area. A descriptive quantitative method is used for this research, by classifying the dependent variables, namely listening intensity, knowledge, so-cialization, implementation, and knowledge distribution. The selected independent variables were age, education, occupation, income, and ethnicity. These variables became the reference in making questionnaire questions to find out the factors that most influence water conserva-tion. The results showed that the knowledge factor possessed by respondents was the main factor influencing the level of awareness in the implementation of water conservation, with a category average value of 4,12. This is supported by the results of the study which show that respondents with a doctoral level of education have a much higher level of awareness than those with a junior high school level of education, with a mean score of 3,36.
