Mapping of coastline changes helps in coastal development and monitoring. The city of Dumai, on the east coast of Riau Province, has undergone significant and radical changes caused by the intervention of humans and nature over the past three decades. This study mapped and measured the rate of change of the coastline of Dumai City for 30 years. The Landsat (TM, and OLI) image series, 1990, 1999, 2008, and 2020 became a data source to generate coastlines through on-screen digitization techniques, then to study the temporal behavior of coastlines using the Digital Shoreline Analysis System (DSAS) and geographic information systems to describe the spatial and temporal variations of coastlines. The results showed that the coastline length during the observation ranged from 123,14 to 125,23 km, while the average accretion rate was 1.17 meters per year while the average abrasion rate was 2.04 meters per year. Those rates of change affected coastline expanded to the sea for 60,82 hectares and eroded 760,20 hectares coastline to the land.

The condition of the waters in Papua is that there are various kinds of marine life in the body of water. One of the water bodies is the Kampwolker River which has a length of 14.15 m with an intlet river (a river that empties into Lake Sentani) which is located in the Kampwolker River watershed to Jl. 2 Expo Arena, Waena. It turns out that the Kampwolker River has a heavily polluted result with a score of 48. GPS and Arcgis Software Version 10.3 show three locations of the Kampwolker river, including: the intake Kampwolker River, the middle Kampwolker River, and the downstream Kampwolker River. Water quality was measured using the STORET method. Analysis of water samples obtained several samples of the most dominantly high chemical parameters, including Phosphate (PO4 – P) of 2.48 mg/l, Copper (Cu) of 0.235 mg/l, and Lead (Pb) of 0.15 mg/l. l. Kampwolker river pollution shows a color change to brown. This is due to the activities of densely populated community settlements, the agricultural industry, mineral C mining, and other industrial fields. Floods and erosion occur due to the ignorance of the community around the Kampwolker river to the importance of ecosystems and drinking water sources for the survival of the people in Jayapura City.

Palangka Raya City is one of the cities affected by COVID-19, where on November 11, 2021, and 13104 people were confirmed positive for COVID-19. The Health Protocol continues to be carried out in this New Normal era. The Health Protocol by washing hands with soap is an environmental issue that needs attention, namely the use of hand soap which reduces surface air quality. Hand soap contains chemicals that can increase the concentration of Chemical Oxygen Demand (COD). There is a need for laboratory testing of the COD parameters of surface water around handwashing facilities in public facilities in the era of new habits. The research was divided into laboratory tests on surface water parameters, namely pH, temperature, and COD as well as field surveys on the use of handwashing facility. The results of laboratory tests show that the quality of surface water on the COD parameter is below the quality standard. The use of handwashing facilities is not justified, because its use is only 19%. Along with the low use of handwashing facilities, hand washing facilities do not have an impact on decreasing surface water quality on the COD parameter, it can be an action to maintain surface water quality.

The waste composition in Boyolali Regency consists of 37.13% garden waste. The waste can be treated with a thermal process so that it can be reused for energy. The method of sorting waste with thermal technology consists of various types adapted to the gods. This study aimed to evaluate the most co-cog heat treatment processes for waste processing in Boyolali Regency. The determination process is carried out using a literature review, while the selection process uses the Analytical Hierarchy Process (AHP) method. The alternatives given in this research are carbonization, pyrolysis, and synergy processes. In the alternative selection, there are three criteria, namely mass balance, CO2 residue, and energy volatility. In terms of mass balance, the waste that the carbonization process can treat tends to be higher than that of the pyrolysis and incineration processes. Meanwhile, the carbonization process is better than pyrolysis and carbonization for wood waste for emission and energy requirements. The result of AHP shows that the carbonization process is suitable to be applied in Boyolali Regency. However, it is necessary to conduct further studies on non-technical aspects to strengthen alternative election results.

Tidal flood and erosion are familiar phenomena in coastal areas that have an impact on the destruction of facilities and infrastructure (water, waste management, drainage) as well as environmental damage which is marked by a decrease in the quality of life of the community. However, the community persisted and chose to stay in the area and the population was increasing from year to year. Community resilience can be seen from several aspects: economic, social, infrastructure, and health. Building community resilience depends on social relationships, networks, and connectedness among communities. This paper reviews and compares the level of community resilience in Portsmouth (UK) and Semarang (Indonesia) to the erosion and flood disasters that hit these regions. With the descriptive comparative method, it is studied how the community's resilience to floods and abrasion is studied. The analysis results show that despite adequate defenses, Portsmouth’s resilience faces a higher economic risk of disasters and the resulting residual risks. Changes that occur on the coast of Semarang City have made people have to carry out a learning process to maintain their lives in the context of adaptation to the social, political, economic, and ecological environment in which the population lives.

Mangrove forest in Sungai Apit Sub District, Siak District, Riau is one of the mangrove ecosystems in Riau Province which has experienced a reduction in land area and is the widest in Siak Regency. This study aims to determine the perceptions and attitudes of the community in the protection and management of mangroves. The research was conducted in three villages in Sungai Apit Sub District, namely Rawa Mekar Jaya, Sungai Rawa and Mengkapan. Data was collected through observation and interviews with the community using mangroves. The results showed that the perception of the community in Sungai Apit towards the function and management of mangroves is classified as very good, while the attitude of the community towards the protection and management of mangroves is classified as good. The perception and attitude of the people of Rawa Mekar Jaya and Meng Kapan are better than the people of Sungai Rawa. Community involvement in rehabilitation activities is generally only at the time of the project and due to wages. The community has a high awareness of utilizing mangrove resources in a sustainable manner. The community has a high awareness of the protection and management of mangroves, but their involvement in rehabilitation activities requires money to compensate for the time and energy used. Therefore, alternative activities are needed that can increase funding sources and increase funding sources in local institutions related to mangroves.

Pneumonia is a type of lower respiratory tract infection and the main cause of under-five mortality, especially in developing countries, with a mortality rate of 3 million each year. Pneumonia cases in children under five in Pelalawan Regency are quite high, namely 72.8% in 2018. Pneumonia is also influenced by climatic condi-tions and seasons. Parasites and disease vectors are very sensitive to climatic factors, especially temperature, humidity, and rainfall. The purpose of this study was to determine the effect of season on the incidence of pneumonia in children under five in Pelalawan District. This type of research is analytic observational with a cross sectional approach. The study population was all patients with pneumonia under five who were recorded in the registration of 12 Puskesmas in Pelalawan Regency in 2018-2019. The research sample uses total sam-pling. Data analysis uses the Vector Autorgressive (VAR) method on time series data with time level being monthly data. The results showed that the trend of the number of pneumonia cases fluctuated approximately every 2 months, this was caused by the influence of the season, namely the rainy season and dry season. Mostly in the rainy season the number of pneumonia cases tends to experience an increasing trend. Based on statisti-cal tests, it is known that seasonal variables (rainfall, rainy days, humidity and temperature) have no signifi-cant effect on the incidence of pneumonia in children under five, but the R Square value in the modeling above is quite good, namely 0.655, meaning that 65.5% of the diversity of pneumonia cases can be explained. by these variables while the rest is explained by other variables outside the model. For this reason, it is hoped that the Puskesmas will campaign for the '5 M' program, especially in the rainy season (opening ventilation, entry of light, entry of air, maintaining house cleanliness and increasing body immunity). It is suggested to the Pelalawan District Health Office to monitor climate factors on an ongoing basis in the context of the pro-gram to eradicate pneumonia in children under five.

The problem that occurs in Lake Sentani is that it has been contaminated by parameters of TSS, BOD, Pb, Cu, and DO respectively with valuesof 76 mg / L, 4.63 mg / L, 0.035 mg / L, 0.03 mg / L, and 5.72 mg / L because these parameters have exceeded the quality standard according to environmental regulations. This study aims to determine the assimilation capacity of TSS and PO4 parameters and analyze pollution control models in the Tlaga Ria sub-watershed. The research method used to determine the assimilation capacity is a linear regression equation and in analyzing the pollution control model the interpretative structural modeling method is used. The results showed that the TSS assimilation capacity value in Lake Sentani was -12,700 tons/month. The value of water quality in Lake Sentani is above the value of the assimilation capacity, this shows that Lake Sentani has been polluted by TSS parameters. Meanwhile, the value of PO4 parameter assimilation capacity is 44.36 tons/month and since 2016 Lake Sentani has been unable to conduct self purification. The key elements of the Sentani Lake pollution control constraints in the Tlaga Ria watershed are weak implementation of environmental regulations, differences in objectives among stakeholders, differences in objectives between administrative areas, weak support of business owners, conflict of interests, and weak enforcement of regulations.

The development of aquaculture in the Marine Protected Area (KKP) has to recognize the sustainability and the balancing of the ecosystem in that area. It causes limited rights of users who want to develop their business, where the issuance of permits and business management regulations is an obligation that must be followed by aquaculture business developers in the KKP area. The study aimed was to formulate the technical directions in developing the potential for aquaculture business in the Marine Protected Area of Datok Bandar (KKPD) at Lingga Regency. The method used in this research is a descriptive quantitative using analysis of the carrying capacity of the environment for aquaculture, water quality parameters, and a participatory approach. The results showed that the potential area to be developed for aquaculture was 3,736.01 ha. However, based on the carrying capacity analysis, only 268,420 ha or 7.2% from the existing potential can be utilized for aquaculture. Furthermore, based on the water quality measurements for aquaculture, the KKPD area was divided into 3 designations groups of aquaculture areas, namely the KJT, KJA, and seaweed. The number of aquaculture business units that were allowed in this area was 16,776 units consisting of 10,066 small business units and 6,710 medium business units with 7 types of superior fish. The limitation of land area and some business units in conservation areas were important to ensure the sustainability of the environment in the future. The implication of this research could be used as a basis for issuing aquaculture business permits, and to ensure that small-scale aquaculture fishermen have a large proportion. In addition to ensuring the existence of local communities who were generally small farmers, conservation areas were very vulnerable to environmental changes, so the risk factors and impacts of business utilization were important to consider.

The needs for added value of agricultural products is increasing, both in the form of health benefits and of reducing pollution waste. The sorting-out fruits that are just wasted can still be used as materials that have added value. In general, fruits contain glucose which is the basic ingredient in processing of bioethanol. Even though the quality has decreased, it still contains glucose which can then be fermented into bioethanol or organic fertilizer. Recently, the pharmaceutical and food and beverage industries require a large supply of bioethanol for further processing according to the industrial needs. Meanwhile, agricultural land is increasingly promoting organic farming. The objective of this activity is to produce new products from fruit waste into bioethanol and organic fertilizers that are useful for both the community and the government so that they can be used as the right solution to reduce environmental pollution and create new business opportunities. Bioethanol processing method uses Saccharomyces cerevisiae as a biocatalyst and uses an EM4 activator to produce organic fertilizers. This activity produces an output product in the form of bioethanol 46.78 % and organic fertilizer which contain 1% N.

Pests that are often a household problem in several cities in Indonesia are mosquitoes, rats, cockroaches, flies. Causes of settlement pests are dirty environments, food scraps, rubbish, and waterlogged gutters / ditches. The presence of pests in the house causes occupants to control pesticides. Pesticides are used primarily to control mosquitoes, ants, flies, cockroaches, mice and termites. This research is a descriptive research that aims to explain, detail and make a description of a phenomenon or object under study. The target population in this study is households residing in Pekanbaru City, namely in the Districts of Tenayan Raya, Sail and Pekanbaru City with three clean, medium and dirty categories. Determination of the sample is done purposively with multistage sampling technique. The sample was determined purposively with multistage sampling technique and the total sample was 101 households. The data obtained were nominal, ordinal and ratio, analyzed the relationship between these data using chi-square. The results showed that the physical environmental factors of housing settlements that affect the presence of residential pests are dirty environments caused by garbage and dirty drainage / ditches. Meanwhile, biotic environmental factors in residential housing that affect the presence of pests are plants grown in residential areas in the form of ornamental plants and unkempt shade plants. The dirty condition of the residential environment is due to the lack of environmental cleaning activities and the not yet routine transportation of waste from residential homes to landfills. In addition, there is less care for ornamental plants and shade in the yard, such as pruning.

The study of ecological characteristics, health conditions and the level of vulnerability of mangrove degradation when initiating North Rupat as a Regional Aquatic Conservation Area (KKPD) was conducted in July 2018 with the aim of future baseline data and comparison. Data collection on the condition of mangrove vegetation is carried out by making line transects and plots drawn from the reference point (outermost mangrove stands) in a direction perpendicular to the coastline to the mainland. The results of the study showed that 12 identified species. The diversity index and dominance are relatively low (H’ ≤ 2.0 and 0 < C ≤ 0.5), while the uniformity is classified as stable (0.75 < E ≤ 1). For the density of mangroves the highest category of trees is at Station 4 (2525 ind/ha ± 638.15), while the density of saplings and seedlings at Station 1 (2800 ind/ha ± 873.48 and 50000 ind/ha ± 17638.34), where Xylocarpus granatum is the dominant species in the tree and seedling category (Importance Value Index/IVI 191.74% and 240.80%), while Avicennia alba was for the saplings category (IVI 216.01%). In the main land part of the North Rupat KKPD area, the mangroves' health condition was increasingly threatened by destruction compared to the small islands around it. However, overall the level of vulnerability of mangrove degradation in the initiating area of North Rupat KKPD is still relatively low.

Factors that significantly influence the income of goldfish cultivators (Cyprinus carpio) at the real level α = 5% are the yield (HP) kg / unit and the number of cages (JK) unit. The surplus value of goldfish cultivation producers (Cyprinus carpio) is IDR 42,102,269,258.00 / year. The results of the analysis of the financial feasibility value (NPV) of Rp. 77,136,617.10, - / unit for the volume of cages 6 x 6 x 4. Whereas for the volume of cages 6 x 8 x 4, it has a value (NPV) which is much greater than Rp. . 173,394,632.39, - / unit. The second value (NPV) is positive based on the criteria for a feasible business investment if the value (Net B / C) is greater than 1, the value (IRR) is the same as 12.00% for both cage size categories. The sensitivity analysis shows that the cultivation of goldfish (Cyprinus carpio) KJA in the Koto Panjang Hydroelectric Power Plant is more sensitive to changes in decreased production compared to changes in decreasing price of carp feed (Cyprinus carpio). Based on the Exponential Comparative Analysis (MPE), it is found that the best alternative development policies to be developed and implemented are capital strengthening and improvement of facilities and infrastructure related to fish cultivation development.

Trawl has the size a mesh size a small size pockets of the cod end. This allows the trawl fishing gear to potentially be a fishing gear that is not selective about the size of the fish and the species that are targeted for its catch. If this fishing gear is left, its existence will eventually have a negative impact on the sustainability of fish resources, especially in coastal waters. The purpose of this study is to calculate the composition and proportion of main catches, bycatch and discarded catches. It is expected that knowing the composition and proportion of the main, by-product and discarded catches can provide an overview of the pressure on stocks and sustainability of fisheries resources in the waters where trawl is operated. The method used in this study is a survey method. A series of survey activities were carried out directly in the field to identify and count the types of species caught by trawlers. Based on the percentage of main catch, by-catch and discard per type, it Matuta planipes are the dominant species caught by trawlers (23.65%). The main catch Parapenaeus longirostris 15.92%. In addition, the main catch caught were Parapenaeopsis sculptilis (9.787%), Penaeus merguiensis (0.646%), Metapenaeus brevicornis (10.118%), Penaeus indicus (0.029%) and Squilla mantis (0.153%). Percentage of bycatch reaches 2.245% of 10 species caught and discarded catches reach 61.103% of 25 species caught.

The high demand for shrimp commodities will increase catching to spur production so that it will affect the shrimp population. This scientific study will discuss the spawning season of banana shrimp (Penaeus merguiensis), catch size, and environmental conditions of Dumai and surrounding waters. This research was conducted from April to December 2018 using survey methods around the waters of Dumai, Riau. Data collection was carried out monthly on 4,677 banana shrimps assisted by enumerators. The analysis was carried out on the relationship between carapace length and body weight, sex ratio, gonad maturity level, and catch size. The condition of the aquatic environment that influences the process of reproduction becomes a comparison in determining management efforts. Banana shrimp size structure 18-60 mm, dominant at 28 mm and negative allometric growth patterns. The genital ratio shows that female shrimp are more dominant than males and the spawning season lasts throughout the year with peaks in June and December. The length at first capture was 34.5 mm with the length at first maturity was 30.8 mm (Lc> Lm), meaning that it had spawned before being capture. However, the polluted water environment can interfere with the process of growth and population growth even though various environmental parameters are still within normal limits. So the thing to do is to close the shrimp catching area in June and December, not catch in the spawning area, the size of the shrimp that can be caught is 31 mm and protect the aquatic environment from pollution.

Abstrac :Plastic pollution / waste has an impact that will disturb the stability of the ecosystem, especially aquatic organisms such as fish. The main source of plastic contamination comes from household waste that is not managed properly, especially in coastal areas that make the sea as a place of final discharge. Plastic pollution is currently the main problem that is accepted by the environment, especially water. Plastic will dissolve in the waters and will form small sizes (micro-plastic) impacting biota, including fish. Fish including aquatic organisms that can not distinguish between food and plastic particles clearly, thus providing an effect on digestion and growth. The results showed the growth rate of silver Pompanoo with the highest plastic concentration will cause slower growth, the control treatment is the best growth yield compared to treatments that have a plastic content mixed with feed. Growth of weights with the highest concentration of plastic particles is 0,48 gr/week, length growth is 0.75 cm / week, and survival is 69.17% and shows the growth and survival rates are worse or there is a tendency to worsen with an increase in the concentration of plastic contamination . Plastic particles consumed by fish are not digested properly and can even cause the growth response of fish to be slow even to death.
