Abstract

A thin layer is a very thin layer of material (organic, inorganic metal or a mixture of organic metals) which has the properties of a conductor, a semiconductor, a superconductor or an insulator. CoFe2O4 nanoparticles are very popular materials to be developed in the field of electricity and magnetism because they have cubic magnetocrystalline properties and high coercivity properties, as well as medium saturation magnetization. Sol-gel is one of the techniques in the manufacture of thin films that involves chemical processes in the form of hydrolysis and condensation reactions. Sol-gel dip coating is a technique for making a thin layer that has several advantages, namely a simple method, easy, few precursors so that it saves production costs and does not damage the environment. XRD test results of a 0.20 M CoFe2O4 thin layer found a peak in the 2Ө 18.1152 region with a diffraction pattern (111). The highest UV-Vis absorbance peak at a wavelength of 285 nm was 2.5423 A and the lowest bandgap value was 2.79 eV. The resistance value is 6.46 and the resistivity value is 0.00016225 m.

Abstract

This research was conducted in February 2021 in the waters of Pandan Island, West Sumatra Province. This study aims to determine the relationship between coral cover and the density of megabenthos found in the Pandan Island area. The method used in this study is a survey method. Coral cover data was collected using the LIT (Line Intercept Transect) method and megabenthos data was collected using the Benthos Belt Transect method. The results showed that Pandan Island had a good percentage of coral cover. The highest density of megabenthos was trokha snails found at each station, while the lowest density was Acanthaster planci which was only found at three stations and had a percentage of coral cover that had an influence on megabenthos density. Then it was also found that there was a strong negative relationship between coral cover and non-economic megabenthos, which indicated that there was an effect of the percentage of coral cover on both economic and non-economical megabenthos.

Abstract

The availability of water from a water source needs to be known so that it can be used as needed. The main use of river water is as raw water whose management is carried out by a Regional Drinking Water Company (PDAM), which is a Regional Owned Enterprise (BUMD) which is engaged in drinking water services. The obstacle that is always experienced by PDAM users is that the service has not been maximized, both in quality and quantity. The purpose of this study was to determine the availability of water from the Siak watershed as a water source for PDAM Tirta Siak in order to meet the clean water needs of the people of Pekanbaru city. The stage of this research is to collect secondary data in the form of rainfall data and climatological data as well as a map of the Siak watershed. Data analysis was carried out by calculating 90% reliable discharge for raw water sources, calculating the clean water needs of the people of Pekanbaru city based on city categories for the population in 2021. The results of calculating the availability of the Siak watershed of 90% reliable flow were obtained at 12.65 m3/s. While the results of the calculation of the clean water needs of the people of Pekanbaru City for residents in 2021 are 1.73 m3/s. Compared to the production capacity of PDAM Tirta Siak which is only 0.08 m3/s, the amount of water available from the Siak Watershed is much larger than the current production capacity requirement of PDAM Tirta Siak.

Abstract

Unlicensed Gold Mining (PETI), was found in 4 districts in West Sumatra including, Dharmasraya covering an area of 1,773 ha, Solok 1,533 ha, Solok Selatan 2,559 ha, and Sijunjung 1,103 ha. PETI is a traditional gold mining activity, the results are processed using the amalgamation method. The amalgamation process in the PETI activity will result in environmental degradation caused by the washing process carried out in the river and the process of refining gold ore by burning which produces mercury vapor (Hg) which evaporates in the air. The amalgamation process can cause negative impacts in the form of environmental pollution by mercury vapor as a result of the process. As much as 10 - 30% of the mercury used in the gold amalgamation process will be released into the environment. The main health problems caused by mercury vapor occur in the brain, lungs, central nervous system and kidneys. The purpose of this study was to describe the level of toxicity that occurs in humans through nails on illegal gold miners in Nagari Koto Tuo Sijunjung, West Sumatra. The benefit of the research is as information that is conveyed to local governments and people who are exposed to heavy metals for the dangers they face. The research method is an observational study with a cross sectional study design, which is a study in which the variables including risk factors and variables including effects are observed simultaneously at the same time. The number of samples used in this study were 13 people. Samples were taken using accidental sampling technique. The method used to determine levels of metallic mercury in nails is wet destruction and examined by AAS. The results of this study used 13 active gold miners with a working period of 20.10 and 5 years with mercury levels of 10.31 mg/kg, 10.04 mg/kg, and 7.30 mg/kg. Based on the results of the standard deviation (SD) test, it was found that the average level of mercury in the nails of gold miner Koto Tuo, Sijunjung was 9.21 mg/kg with an average working life of 34 years and a standard deviation of 1.665. Mercury is a neurotoxin if used in high doses can damage the person's organs.

Abstract

A healthy environment is very important for people's lives, especially in urban areas. Pekanbaru City is one of the cities in Indonesia that is working on the Wastewater Treatment Plant (WTP) project. However, there are development constraints in the surrounding environment. Many parties expressed dissatisfaction with the idea of the Pekanbaru city government. Congestion, economy, road damage, property damage, and environmental problems caused by dust and water during the project are. The problem that has occurred is one example of an environmental communication study that requires stakeholder participation to be resolved. The purpose of this research is to identify the environmental pollution caused and the Government's communication strategy in responding to this problem.
