Abstract

The tradition of Merarik Kodeq, or early marriage, remains a serious issue for the Sasak community in West Nusa Tenggara. The aim of this study is to explore the ethnobiological perspective on the Merarik Kodeq culture in West Lombok and to identify the efforts made by the local government of West Lombok Regency to curb the growing prevalence of Merarik Kodeq. This study uses a descriptive qualitative method. Informants were selected using purposive sampling based on specific criteria, namely couples who married at an early age. The results show that the average age of early marriage in Sekotong Barat Village is 16–17 years. At this age, reproductive organs are still in the developmental stage, especially the female reproductive system, which functions as the place for fetal development. Therefore, pregnancies occurring at this age pose a high risk of miscarriage, birth defects, and even maternal and infant mortality. In response to the increasing rate of Merarik Kodeq or early marriage, the local government initiated a movement known as the Anti-Merarik Kodeq Movement.

Abstract

Taliwang Swamp Lake is a source of livelihood for the people of West Sumbawa. High levels of local activity, such as agriculture and mining, have the potential to pollute the lake with mercury (Hg) due to waste from the amalgamation process and fertilizer residues flowing into the lake. This study aims to determine the heavy metal content of mercury (Hg) in snakehead fish (Channa striata) from Rawa Taliwang Lake and its suitability for consumption. Sampling was carried out using a purposive sampling technique at both stations. The criteria for selecting the sampling location were that it could represent the west and east sides of the lake and also take into account the fishing points that could be accessed, considering that the lake was partly covered with vegetation. Data analysis included determining mercury (Hg) levels using a mercury analyzer. The results showed that the mercury (Hg) content in snakehead fish was 0.078 mg/kg. This level is still suitable for consumption according to Food and Drug Supervisory Agency (BPOM) regulation No. 9 of 2022.
