Magnetic susceptibility and heavy metal contents in sediments of Riam Kiwa, Riam Kanan and Martapura rivers, Kalimantan Selatan province, Indonesia.

Kalimantan Selatan is proud of the Martapura River's natural and cultural history. Martapura tributaries include Riam Kanan and Kiwa. The Martapura River is essential because it provides clean water and a livelihood for riverside residents. Human-caused river pollution grows with population density (also known as anthropogenic pollutants). This study characterizes surface sediment magnetic characteristics and heavy metal contents along the Riam Kanan, Riam Kiwa, and Martapura rivers. The purpose of this research is to evaluate the magnetic signal with respect to heavy metal contents found in surface sediments taken from rivers and to confirm the use of the rock magnetism method in environmental studies in the study area. Surface sediment samples were gathered and tested for magnetic, heavy metal, and mineralogical content. According to the findings, the pseudo-single domain (PSD) magnetite mineral predominates among the magnetic minerals that can be found in the surface sediments of the rivers Riam Kanan, Riam Kiwa, and Martapura. This substantially greater grain size may be due to magnetic particles produced by erosion along the river banks. The mass-specific magnetic susceptibility of surface sediments ranges from 103.11 to 1403.64 × 10-8 m3/kg, with an average value of 355.67 × 10-8 m3/kg due to the peatland environment. Magnetic susceptibility strongly negatively correlates with heavy contents like Cu, Zn, and Hg, according to Pearson correlation analysis. Due to this correlation, magnetic susceptibility may indicate heavy metal pollution in certain rivers. This current study demonstrates the novelty of the relationship between magnetic susceptibility and the contents of heavy metals in surface sediments from rivers in peatland and tropical environments by illustrating how the relationship affects the magnetic susceptibility of the sediments.

Hair disorder in dr. Cipto Mangunkusumo cosmetic dermatology and venereology outpatient clinic of Jakarta, Indonesia: A socio-demographic and clinical evaluation.

Hair disorder has a significant impact on sociopsychology. In Indonesia, there are currently few and out-of-date studies on hair disorders. Our study aimed to provide an update on the epidemiology of hair loss, which is common in Indonesia. This is a retrospective study of hair disorder cases seen at Dr. Cipto Mangunkusumo's Cosmetic Dermatology Outpatient Clinic at the National Central General Hospital from January 2017 to December 2019. Each patient's age, gender, family history, education, occupation, body mass index (BMI), comorbidities, and diagnosis were recorded. Hair disorders were found to be more prevalent in males (54.6 percent) with a mean age of 26.41 ± 12.8 years old and the highest age group of 18-39 years old (59.4 percent) among the 64 patients who were eligible for the study. There were 32 cases (50.0%) of alopecia areata (AA), 20 cases (31.2%) of alopecia androgenetic (AGA), 9 cases (14.0%) of telogen effluvium (TE), 2 cases of cicatricial alopecia (CA) due to lupus erythematosus (DLE), and 1 case of trichotillomania (TTM). Female patients had significantly more TE cases. Cases of AGA in the study, mainly early-onset AGA (mean age 29.45 ± 10.29 years old, 39.5% in 18-39 years old) showed a significant positive familial history. At dr Cipto Mangunkusumo National General Hospital Jakarta, the most common types of hair disorders were AA, AGA, and TE, with each disease having a unique socio-demographic and clinical profile.

Magnetic susceptibilities of surface sediments from estuary rivers in volcanic regions.

Estuaries have very complex mechanisms because they are influenced by seawater intrusion, which causes enrichment of contaminants in the maximum turbidity area. Magnetic susceptibility measurements have been used for monitoring a wide variety of environments. However, there have been few studies of the magnetic properties of surface sediments from estuaries in volcanic environments in the tropics. This study investigates the magnetic properties and their correlations with the geochemistry of surface sediments in estuaries in volcanic areas and was conducted in the Krueng Aceh River, Indonesia. Measurements consist of magnetic susceptibility measurements, chemical analysis, and mineralogical analysis. Measurements of magnetic susceptibilities were performed using a Bartington MS2 instrument with an MS2B sensor using frequencies of 460 and 46 kHz. X-ray fluorescence (XRF) and energy-dispersive spectroscopy (EDS) were used to identify elements in the sediments. Scanning electron microscopy (SEM) analysis was used to analyze sediment grains. X-ray diffraction (XRD) analysis was used to determine mineral contents. For the first time, χLF/χFD ratios were found to be an obvious parameter for identifying areas of sediment traps and metal enrichment in the estuary turbidity maxima (ETM) zone. The magnetic properties carried by volcanic rock minerals consist of pigeonite and enstatite. These two minerals have not been previously considered as carriers of sediments with magnetic properties when monitoring heavy metal enrichment in urban rivers. These results provide an extension of the use of magnetic susceptibility measurements in environmental studies, particularly in estuary river environments in volcanic areas such as the Krueng Aceh River, Indonesia.

Type 2 Diabetes Mellitus with Early Dry Skin Disorder: A Comparison Study Between Primary and Tertiary Care in Indonesia.

BACKGROUND: The prevalence of Type 2 Diabetes Mellitus (T2DM) in Indonesia has continued to increase over the years. Management of T2DM is challenging across clinical settings, including primary and tertiary care. Uncontrolled T2DM puts patients at risk of the development of T2DM complications, especially early-stage dry skin that is neglected by most of the patients. This study aimed to investigate the comparison between the T2DM management profile and dry skin clinical profile of T2DM patients in primary care and tertiary care settings. METHODS: The study was conducted as a cross-sectional epidemiological study by comparing T2DM patient profiles in primary and tertiary care. The data collected included sociodemographic, clinical, and laboratory data that were correlated with T2DM and early dry skin related-T2DM. This study included early dry skin within the SRRC score of 3-11 and excluded infection, ulcer, and severe erythema. RESULTS: The patients in primary and tertiary care presented poorly controlled T2DM with median HbA1c levels of 7.8% and 7.6%. The patients in primary care also presented with high triglyceride, 179 mg/dl. Furthermore, several significant differences were found in the duration of T2DM, duration of dry skin, and DM treatment (OAD and insulin). CONCLUSION: Significant differences in the duration of T2DM, duration of dry skin, and DM treatment (OAD and insulin) might be affected by the parameter of T2DM glycemic control (Blood pressure (BP), body mass index (BMI), HbA1c, random blood glucose (RBG), and triglyceride).

Towards an optimal hybrid solar method for lime-drying behavior.

Lime is one of the most commonly consumed medicinal plants in Indonesia, which must be dried to preserve its quality, but mostly by using traditional, ineffective drying method. Therefore, this study aims to investigate lime drying process a hybrid solar drying method. The hybrid solar dryer consisted of a solar dryer and Liquefied Petroleum Gas as the supplementary heater. The drying process was conducted until there was no significant weight decrease, with the drying temperature of 40, 50, 60, 70, and 80 °C. Thin-layer modeling and quality analysis were also conducted. The experimental results indicated that 5 h was required to sufficiently dry the lime at 80 °C, while drying at 40 °C took 24 h to finish. The drying rate curve of lime suggested that lime drying mostly happened during the falling-rate period. Moreover, the average efficiency of the hybrid solar dryer ranged from 5.36% to 38.61%, which increased with temperature. From the 10 thin-layer drying models used, the Wang and Singh model was the most suitable to describe the drying behavior of lime. The effective diffusivity values of the limes and the activation energy value during hybrid solar drying were within their respective acceptable range for agricultural products. However, as the drying temperature was increased from 40 to 80 °C, the total phenolic content and vitamin C content decreased, from 87.3 to 27.8 mg GAE/100 g dry limes and 0.118 to 0.015 ppm, respectively. It can be concluded that hybrid solar dryer is able to sufficiently dry the lime, with acceptable drying time and dryer efficiency, although using high drying temperature will decrease the quality of dried lime. Further modifications and improvements to the hybrid solar dryer are required to maximize the quality of dried lime while still maintaining fast and effective drying process.

Petrology and geochemistry dataset of lava from the Ijen Crater and Mount Blau, Banyuwangi, East Java, Indonesia.

This article presents rock texture and mineralogy, as well as major and trace elements of lava from Ijen Crater and Mount Blau, Ijen Volcanic Complex (IVC), East Java, Indonesia related to article entitled "Rock Magnetic, Petrography, and Geochemistry Studies of Lava at the Ijen Volcanic Complex (IVC), Banyuwangi, East Java, Indonesia" [1]. Six lava samples were taken from three lava flows that are the product of the eruption of the Ijen Crater and three lava samples from a lava flow that is the product of the eruption of Mount Blau. The samples were crushed and used for measuring major and trace elements using XRF method. Meanwhile, the thin sections of all samples were used to analyze rock texture and mineralogy. These data are invaluable in identifying the lithology, tectonic setting, and magmatism process through the analysis of total silica alkaline and Harker diagram. Other researchers can analyze the other diagrams and graphs to know in more detailed information as intended. On the other hand, the data can be used as a comparison for other lava products from different eruption sources.

Environmental magnetism data of Brantas River bulk surface sediments, Jawa Timur, Indonesia.

This article presents measurement data using environmental magnetism method on the bulk surface sediments related to the research article entitled "Heavy metal contents and magnetic properties of surface sediments in volcanic and tropical environment from Brantas River, Jawa Timur Province, Indonesia" Mariyanto et al., 2019. Surface sediments were taken from 20 different locations along Brantas River. In the laboratory, a series of magnetic measurements was conducted on sediment samples i.e. magnetic susceptibility, ARM (Anhysteretic Remanent Magnetization) and IRM (Isothermal Remanent Magnetization). These environmental magnetism data were used to characterize bulk surface sediments in the study area.

Heavy metal contents and magnetic properties of surface sediments in volcanic and tropical environment from Brantas River, Jawa Timur Province, Indonesia.

Brantas River is a largest urban river supplying raw water and drainage in Jawa Timur Province, Indonesia. Dense population along the river is a threat of pollution due to anthropogenic pollutants. In this study, we characterize the magnetic properties and heavy metal contents of surface sediments in various locations along the Brantas River. This study aims to enhance our understanding of the relationship between magnetic parameters and heavy metal contents in surface sediments from river. Surface sediment samples were taken and measured by a series of magnetic measurements, mineralogical analysis and heavy metal contents. The results show that magnetic minerals in surface sediments of Brantas River are dominated by PSD magnetite mineral. This relatively coarser grain size can be caused by magnetic particles produced by erosion around the river. Surface sediments have very high mass-specific magnetic susceptibility varying from 844.0 to 7231.4 × 10-8 m3kg-1 (on average of 3022.9 × 10-8 m3kg-1) because influenced by the surrounding volcanic environment. Magnetic susceptibility can identify and classify enrichment of heavy metals. Based on the Pearson correlation analysis, magnetic susceptibility has strong positive correlation with the heavy metal contents of ferromagnetic elements such as Fe and Co so that it can potentially be used as an indicator of pollution of both these heavy metals in the Brantas River. This present work shows the novelty of the relationship between magnetic susceptibility and heavy metal contents in surface sediments from river in volcanic and tropical environment.
