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

Coral reefs are a unique ecosystem of tropical waters that have physical function as a beach protector with its nature that can reduce the energy of waves moving towards the coast. Coral reef ecosystems are a good places for spawning, nurturing and food sources for fish. The aim of this research was to determine the density of zooxanthella on coral Acropora sp based on different depths. The method that used in this research was a survey method by taking coral samples using purposive sampling technique, then the samples were analyzed and the data was discussed descriptively at the Marine Biology Laboratory, Faculty of Fisheries and Marine, Riau University. The results of this research on the waters of Talam Island obtained a brightness up to 100% of depth, a current velocity was 0.05–0.10 m/s, temperature ranging from 30-32 0C, salinity of 34 o/oo and pH ranging from 7.2–7.6. The corals that used as research objects for zooxanthella density were taken at a depth of 3 m, 5 m, and 7 m, namely the coral Acropora sp. The results showed that the average zooxanthella density on Acropora sp coral at a depth of 3 meters was 6.35x106 cells/cm2, a depth of 5 meters was 2.63x106 cells/cm2, and 1.95x106 cells/cm2 at a depth of 7 meters. Based on observations, the density zooxanthella was decreased by increasing depth.

Abstract

The Chaetodontidae family fish is an indicator species because it has a close relationship with coral reefs based on a strong preference for coral stone as the main component of coral reefs. The existence of these fish can be used as a guide to assess and monitor the condition of coral reefs. This study was conducted in March 2022. The purpose of this study was to determine the abundance of reef fish of the Chaetodontidae family in the waters of Talam Island, to determine the condition of life coral cover and the relationship between the abundance of the Chaetodontidae family and coral cover. The method used in this study is a survey method. Data collection on reef fish of chaetodontidae family was carried out using the Underwater Visual Census (UVC) method and coral reefs condition data collection was done using the Line Intercept Transect (LIT) method. The results showed that the abundance of Chaetodontidae ranged from 710 to 1,430 individuals/ha with an average of 1,110 individuals/ha. The highest abundance of 1,430 individuals/ha at station III with a depth of 6 meters, while the lowest abundance was station II with a depth of 8 meters which was 710 individuals/ha. The percentage of life coral cover at each station ranged from 47.70% - 56.98%, 42.60% - 54.40% and 56.68% - 69.08%. Based on these percentages, the average percentage of life coral cover is 54.74% (good category), and there is a very strong relationship between life coral cover and the abundance of the Chaetodontidae family.

Abstract

Even in the setting of schools, open burning of rubbish is still frequently practiced. This is in conflict with the government's program connected to the Pollution Control Strategic Plan (2020–2024), which has the goal of lowering greenhouse gas emissions, and the waste management policy (Law No. 18 of 2008). The justification is that the waste cannot be carried to the TPS or TPA, preventing it from building up and having negative effects like pollution. Lack of awareness, bad habits, and the idea that burning trash is simple and inexpensive are the causes. This issue also exists in SMPN 1 and SMPN 5, Bangko Pusako District, where waste is still managed conventionally by burning it all together without sorting it (visually, 40% of the waste is plastic). The quantity of waste in the two schools, as well as the timetable for its transfer to the disposal/burning site, have not been under control. Because the school has not demonstrated any sort of effective waste management, this requirement makes it more difficult for it to meet the target date for applying for SMP with the Adiwiyata predicate (in 2022). It is known from interviews and the findings of research questionnaires that the school is well-versed in the processes and effects of waste management (including plastic waste). Due to the limited infrastructure, expense, time, and governing laws, they have not been able to participate more. Through an educational approach to improving management conditions regarding the nature of the school as an educational area, and by empowering students as the main component of the school, an optimization of plastic waste management strategies at SMPN 1 and SMPN 5 Bangko Pusako was carried out in this study. Understanding is imparted by repeated verbal socialization, inclusion in instructional materials, use as an example in school life, as well as the creation of policies that have been unanimously agreed upon. Each part of the school is expected to reduce the amount of plastic trash produced, sort waste into its appropriate categories before disposal, reuse waste whenever possible to keep it out of the environment's rubbish heaps, and refrain from burning waste. Due to the majority of the debris being given to scavengers and stacked up, the results indicated a decrease in the volume of waste produced and the frequency of burning. The trash's contents may appear more appropriately for each type. Some plastic products have been replaced with other recyclable materials by students and instructors. This method of controlling plastic waste in the school setting is anticipated to serve as a good model for other schools.

Abstract

This research was conducted in March 2022 in the waters of Talam Island, Central Tapanuli Regency, North Sumatra Province. This study aims to determine the relationship between coral cover and the density of megabenthos in the Talam Island area. The method used in this research is a survey method. Coral cover data were collected using the LIT (Line Intercept Transect) method and megabenthos data were collected using the BBT (Benthos Belt Transect) method. Observations were made at three station points with each station with a depth of 4 meters, 6 meters and 8 meters. The results showed that Talam Island had a good percentage of coral cover with an average of 54.74%. The highest density of megabenthos was Tridacninae found at each station, while the lowest density was Acanthaster planci. The overall megabenthos density has an average of 10.033 ind/ha. Coral reef cover relationship has an influence on the density of megabenthos, there is a strong positive effect on economic megabenthos and a strong negative on non-economic megabenthos.
