Susceptibility and Metallics Elements in Soil Struck by Lightning in West Kotawaringin Regency, Central Kalimantan

Abstract Magnetic susceptibility is a magnetic parameter that assesses a magnetic material’s susceptibility to external magnetic fields. Magnetic susceptibility values can determine the properties of magnetic minerals related to the elements they contain. This research aims to determine the value of magnetic susceptibility and metal element content in soil struck by lightning in West Kotawaringin Regency. Sample measurements were performed using the Bartington MS2B instrument to determine the magnetic susceptibility value and XRF (X-ray fluorescence) to determine the metal element content in the soil samples. The magnetic susceptibility value obtained for sample A with low frequency (<10 strikes per month) was 26.1 x 10−8 m 3/kg; for sample B with medium frequency (11–200 strikes per month), it was 538.4 x 10−8 m 3/kg; and for sample C with high frequency (>20 strikes per month), it was 24.4 x 10−8 m 3/kg. Fe (388,000 mg/kg) was the most prevalent metal element in samples B and C, while element V (300 mg/kg) was the least prevalent in sample A. The sample with the highest metal element content was Fe (388,0 mg/kg), while sample A had the lowest metal element content, V (300 mg/kg). The highest correlation value between magnetic susceptibility and metals is 0.9 (K); 0.96 (Cr); 0.98 (Fe); and 1.00 (Ca, Ni, Zn, and Re).

Public Perception of the Food Estate Program of Cassava Cultivation as a Strategic Logistic Reserve in Realizing Regional Food Security in Gunung Mas Regency, Central Kalimantan

Gestational Diabetes Mellitus (GDM) is a collection of symptoms that arise in pregnant women caused by an increase in blood glucose levels due to a progressive decrease in insulin secretion, variables that influence the incidence of gestational diabetes include age, history of diabetes mellitus, can occur at any time, but this disease usually begins to attack in the 24th week of pregnancy. The prevalence of Gestational Diabetes Mellitus in Indonesia is still relatively small, namely around 3-5%, but this figure could be higher because cases of GDM are rarely detected. Even though it can heal on its own, that doesn't mean gestational diabetes is not dangerous. If not treated properly, this disease can increase the risk of the baby being born with excess weight, being born prematurely, or being born with low blood sugar or hypoglycemia. For pregnant women, gestational diabetes has the potential to cause complications, such as preeclampsia and hypertension. In Indonesia, all pregnant women are recommended to undergo DMG screening. However, not many pregnant women do this. The aim of this research is to determine the relationship between the perceptions of pregnant women and the behavior of early detection of Gestational Diabetes Mellitus at the Plumbon health center, Indramayu Regency in 2024. This research is quantitative research with a cross-sectional study design.
