This research was conducted in February until March 2017 at Pandan Island island pandan area tourist Park Pieh Island. The purpose of this study was to investigate the characteristics of the nesting habitat of the hawksbill turtle (Chelonia mydas). The method used in this research is the survey method, with measuring directly on the habitat of hawksbill turtle covering the slope of the beach, texture of sediments, within the nest of tides, the temperature of the nest, fecundity, and the type of vegetation and predators in the nesting habitat. The results showed that the nesting habitat characteristics vary between nest with each other. Nesting beach ramps ranged 2,75-4,60º with medium sand sediment texture to coarse sand. Temperatures nest ranging between 27-31ºC. The dominant vegetation in the area is a nesting plant pandan laut (Pandanus tectorius) whereas the dominant predator was biawak (Varanus salvator).

This research was conducted in March 2020 to find out the difference in planktonic diatoms abundance vertically at each station in the waters of Nareh Beach, Manggung Village, North Pariaman Sub-District, Pariaman City, West Sumatra Province. The method used is a survey method that consists of three depths at three observation stations. The water quality measured in this study were temperature, brightness, pH, salinity, current velocity, and depth. Based on the research results, there are 11 types of planktonic diatoms found in the waters of Nareh Beach, namely Gyrosigma sp., Chaetoceros sp., Odontella sp., Rhizosolenia sp., Pleurosigma sp., Thalassionema sp., Leptocylindrica sp., Coscinodiscus sp., Nitzschia sp., Guinardia sp, and Skeletonema sp. the most dominant one. The highest total value of planktonic diatom abundance ranges (9779.65-12867.96 ind/L) is found in the surface layer and the lowest ranges (2573.59-10294.37 ind/L) is at 5 m depth. There is no difference in the total value of planktonic diatom abundance between depths

Sponges are the most primitive multicellular animals that live in various types of waters from freshwater, brackish and sea. Sponges live in bottom waters that typically stick themselves on hard substrate such as rock or coral and compete with other tacks organism to obtain a food hall. The research was conducted in Kasiak Island Pariaman regency West Sumatera in February-March 2019, aims to find outthe type, density, frequency of occurrence, diversity index, dominance index, the distribution pattern of sponge, To support the research data is also observed the characteristics of the environment such as water quality. The method used is survey method, where sampling using belt transect method performed on three stations. The research found 14 genus / species of sponge consisting of 11 families in island waters Kasiak with sponge density values obtained in each research station ranges from 1458-4208 ind / ha. The highest frequency of occurrence of the type Jaspis sp. with the frequency of occurrence of 100%. Diversity index values ranged from 1.8921 to 1.9488, dominance index value obtained was from 0.3163 to 0.3396, and the value of the distribution pattern of the sponge ranges from 0.2941 to 0.3015.

Coral reefs are one of the ecosystems that have ecological functions for marine life, one of which is reef fish. Coral fish are marine biota that live in association with coral reefs. This study aims to determine the abundance of reef fish, the condition of coral reefs and the relationship between abundance of reef fish and coral reefs. This research was conducted in June 2019 in the waters of Tikus Island, Bengkulu City. The method used is a survey method. Data collection on reef fish was carried out using the Underwater Visual Census (UVC) method and coral reefs condition data colletion is done using the Line Intercept Transect (LIT) method. The abundance of reef fish found at the study site averages in the abundant category. At station I, an abundance of reef fish was 2,18 ind/m2, at station II it was 4,18 ind/m2, and at station III it was 1,27 ind/m2. While the average condition of coral reefs at the study site is include in the medium category. At station I, the percentage of live coral cover was 39,30% or include in the medium category. At station II, the percentage of live coral cover was 50,94% or include in the good category. And at station III, the percentage of live coral cover was 46,32% or include in the medium category. Coral fish and coral reefs have a fairly close relationship. Reef fish use coral reefs as a place to find food, shelter and spawn or breed.

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.

According to DLHK Pekanbaru 2021 Report, hotel wastewater makes a significant contribution to environmental problems in Pekanbaru. Many hotels don’t have an IPAL permit and don't report the results of the wastewater quality test to DLHK. This will have an impact on the environment in the community. This study aims to examine the strategy of controlling environmental pollution by hotel wastewater in Pekanbaru. The research method is in the form of surveys, interviews and questionnaires to determine the quality of processing and control strategies for environmental pollution that can be caused. Used descriptive analysis and SWOT analysis. The results of this study: there are hotel BOD and COD values that do not meet the quality standards of Minister of Environment Regulation No. 5 of 2014 due to the influence of visitors and the rainy season, but the values of TSS, pH, ammonia, oils and fats, and total coliform have met the quality standards. There needs to be an evaluation related to hotel wastewater treatment, improvement of policies related to hotel wastewater treatment in accordance with applicable quality standards, sanctions for hotels that are negligent and do not comply with the rules, socialization to the public to care about the environment.
