Abstract

Safitri R, Riswanda J, Armanda F. 2020. Monitoring of  heavy metal polution the lead (Pb) with bio indicator baung fish (Hemibagrus nemurus) at the Musi River of South Sumatra. Jurnal Lahan Suboptimal : Journal of Suboptimal Lands 9(2): 127-138.The high activity of the community in the musi river waters could affect the quality of river water, and can even caused water pollution and aquatic biota including fish baung (Hemibagrus nemurus) by lead heavy metals (Pb). This study aimed to determine the lead (Pb) heavy metal content of baung fish (H. nemurus) catches of fishermen in the musi river waters of palembang city. This research was conducted in May-June 2019. The method used is quantitative descriptive. The sample of this research is the meat, skin, liver, kidney and gill of baung fish (H. nemurus) which are tested for lead (Pb) heavy metal content using aas (atomic absorption spectrophotometry). The results of this study indicated that the concentration of heavy metal the lead (Pb) in fish baung (H. nemurus) in the waters of the musi river on the average meat of 0.046 mg/kg, on the skin of 0.058 mg/kg, in the liver of 0.1516 mg/kg, in the kidney at 0.2513 mg/kg, and in the gills at 0.2216 mg/kg. The Pb concentration on the meat, skin and liver samples were still below the established quality standards so that they were still suitable for consumption while the kidney and fish gill samples are above the quality standards that have been set based on the regulations of the Regulations Drug and Food Control Agency (DFCA) number 5 of 2018 which is equal to 0.20 mg/kg.

Abstract

Pediculosis capitis affects all races and all social levels, but low socio-economic status is more affected by this disease. The mode of transmission can be direct (hair to hair) or through intermediaries such as hats, pillows, mattresses, combs, and veils. This study aims to analysis of socio-economic status, morphology, and dominant factors of personal hygiene behavior on the incidence of pediculosis capitis at Orphanages in Palembang City, Indonesia. The cross-sectional design is a sample of all orphanages in Palembang City. The results obtained were then analyzed by chi-square, logistics regression statistical test, and correspondence analysis. Morphology of pediculosis capitis female body length is 2461.70µm, male is 2596.90µm. Antenna shape are shorter and wider, abdomen curve is protruding. Crest of the paraterga plate is extends into the intersegmental membrane. Knowledge of respondents is not good and suffers from pediculosis capitis by 43 (74.1%), knowledge of respondents is good 52 (57.8%), attitude of respondents is negative and suffers from pediculosis capitis 27 (87.1%), positive attitude of the respondent suffered from pediculosis capitis 25 (42.4%), the respondent's actions were not good and suffered from pediculosis capitis 34 (75.6%), the respondent's action was good 18 (40%). The results of the logistic regression test: the most dominant factor is the attitude of the respondents (OR: 6.260 95% CI: 1.836-21.34). This research needs to be continued with individual characteristics in improving behavior in preventing pediculosis capitis.

Abstract

Zingiberaceae is a family of spice plants that are commonly found in the Sriwijaya Botanical Gardens, this type of plant is often used as medicine, cooking spices, ornamental plants and hair medicine. Families of Zingiberaceae are still not well identified. This study aims to determine the species of the Zingiberaceae families in the Sriwijaya Botanical Gardens. This research uses descriptive qualitative research and uses the method of exploring the location in the Kebun Raya Sriwijaya. The identification results obtained six species of plant species from the Zingiberaceae family, namely galangal: Alpinia galanga (L.) Wild., yellow turmeric: Curcuma longa L., kencur: Kaempferia galanga L., white turmeric: Curcuma zeodaria (Christem.) Roscoe., ginger white : Zingiber officinale var. amrum., and forest galangal : Alpinia malaccensis.
