Abstract

Papua, the easternmost province of Indonesia, has consistently reported the highest number of new leprosy cases and leprosy-related disabilities for decades. Despite this burden, no comprehensive study in recent years has systematically examined the epidemiological trends of leprosy in Papua using large datasets. This study provides an updated analysis of leprosy elimination efforts and evaluates the province’s readiness to achieve the Zero Leprosy 2030 target. A retrospective descriptive epidemiological review was conducted using secondary data from the routine health information system of Papua Province from 2020 to 2024. Extracted variables included demographic characteristics, new case reports, diagnostic classification, disability grade, case-finding method, and clinical outcomes. Data were analyzed descriptively and presented in tables and figures to illustrate temporal trends. Between 2020 and 2024, a total of 3,909 new leprosy cases were reported, with fluctuating case detection rates. Multibacillary (MB) leprosy predominated, particularly among males, although females also contributed a substantial proportion of MB cases. Child cases showed an increasing trend, accounting for up to 20% of all new cases. Most cases were detected at Grade 0, with passive case finding as the dominant detection method. Treatment outcomes showed that approximately 70% of patients were released from treatment annually, but relapse and default remained considerable. These findings highlight that Papua is still far from reaching the Zero Leprosy 2030 goal. Strengthening active case finding, improving treatment adherence, reducing stigma, and enhancing reporting and evaluation systems are urgent priorities. Sustained political commitment from local leadership will be crucial to ensure the successful implementation of these strategies.

Abstract

The existence of water plays an important role in the lives of all living creatures. Water distribution on the earth’s surface is divided into sea water and fresh water. Rivers are an example of surface fresh water that provides a water source for life. Water quality plays a role in determining a river’s quality status and designation. The Widas River is a sub-watershed of Brantas located in Nganjuk Regency. Based on Government Regulation 61 of 2010, the Widas River is included in class II for the river category. The research was carried out to assess the water quality and quality status of the Widas River. The method used in descriptive-quantitative was obtained by applying the pollutant index method. Water quality data shows that the Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) parameters exceed the established class II quality standards, namely 3 mg/L for the eiver category. Meanwhile, the Widas River’s quality status, with a value of 2,22 using class II quality standards and 1,28 using class III quality standards, is included in the lightly polluted category. Meanwhile, with a value of 0.75 using class IV quality standards, it is included in the river category with good content. Based on this, class III quality standards in Government Regulation Number 2 of 2021 are more appropriate for the Widas River, Nganjuk Regency.
