Abstract

The objective of this study is to determine the sensitivity of Citarum river flow to climate change and land conversion. It will provide the flow information that required in the water resources sustainability. Saguling reservoir is one of the strategic reservoirs, which 75% water is coming from the inflow of Upper Citarum measured at Nanjung station. Climate variability was identified as rainfall variability. Sensitivity was calculated as the elasticity value of discharge using three-variate model of statistical approach. The landuse conversion was calculated used GIS at 1994 and 2004. The results showed that elasticity at the Nanjung station and Saguling station decreased from 1.59 and 1.02 to 0.68 and 0.62 respectively. The decreasing occurred in the before the dam was built period (1950-1980) to the after reservoirs operated period (1986-2008). This value indicates that: 1) Citarum river flow is more sensitive to rainfall variability that recorded at Nanjung station than Saguling station, 2) rainfall character is more difficult to predict. The landuse analysis shows that forest area decrease to ± 27% and built up area increased to ± 26%. Those implied a minimum rainfall reduction to± 8% and minimum flow to ± 46%. Those were caused by land conversion and describing that the vegetation have function to maintain the base flow for sustainable water resource infrastructure.

Abstract

COVID-19 telah menjadi tantangan kesehatan masyarakat global dan merupakan penyakit dengan transmisibilitas yang tinggi. Untuk itu, masyarakat harus melakukan tindakan pencegahan untuk membatasi penyebaran COVID-19. Elemen kunci seseorang untuk melakukan tindakan preventif untuk melindungi dirinya dan orang lain adalah persepsi terhadap risiko. Persepsi risiko ini dapat terdistorsi oleh berbagai bias kognitif yang dapat mendera masyarakat. Dengan menggunakan metode survey daring (dalam jaringan) terhadap 391 responden di Jawa Barat, penelitian ini bertujuan untuk memahami persepsi risiko terhadap pencegahan penularan COVID-19 dan bias kognitif yang menyertainya. masih terdapat responden yang merasa yakin benar bahwa Indonesia relatif aman dari COVID-19 karena beriklim tropis, COVID-19 dapat disembuhkan hanya dengan meminum obat herbal atau pengobatan tradisional lainnya, dan merasa aman untuk bepergian ke tempat umum. Sebanyak 74,9% responden bersedia menjalani vaksin, dan 25,1% responden tidak bersedia menjalani vaksin. Penelitian ini menunjukkan bahwa persepsi responden terhadap COVID-19 masih perlu ditingkatkan agar perilaku masyarakat pada masa Adatasi Kebiasaan Baru (AKB) tetap mematuhi protokol kesehatan. Selain itu, pengetahuan tentang vaksin pada responden perlu ditingkatkan melalui pemberian informasi yang lebih strategis dan masif.
