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 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.

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.
廖内省Siak区Sungai Apit街道的红树林是廖内省陆地面积减少的红树林生态系统之一，是Siak县面积最大的红树林。这项研究旨在确定社区对红树林保护和管理的看法和态度。研究在Sungai Apit街道的三个村庄进行，即Rawa Mekar Jaya, Sungai Rawa和Mengkapan。通过对使用红树林的社区的观察和访谈收集数据。结果表明:双溪Apit社区对红树林功能和管理的认知为“非常好”，对红树林保护和管理的态度为“好”。拉瓦麦卡加亚和孟卡潘人民的认知和态度比双盖拉瓦人民要好。社区对康复活动的参与一般只在项目进行时和由于工资的原因。社区对以可持续的方式利用红树林资源有很高的认识。社区对红树林的保护和管理有很高的认识，但他们参与恢复活动需要金钱来补偿所花费的时间和精力。因此，需要其他活动来增加资金来源，并增加与红树林有关的地方机构的资金来源。

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 need for data and information is an essential issue in sustainable mangrove management. The availability of data from authorized institutions is essential considering the reliability and consistency of the data, both to process techniques and data availability. This study used national mangrove and landcover data produced by the Ministry of Environment and Forestry through online services. 11 data series (2000 – 2019) obtained through the Representational State Transfer (REST) Application Programming Interface (API) service. Application of spatial analysis of vector data through geoprocessing tools and attribute data management to determine the distribution and changes in mangrove cover and the factors that trigger changes. Estimated data indicate a 13.4% decline in mangroves in Riau Province, with an average decline of 2,495.9 hectares/year. Over 98% of mangrove changes into other functions are caused by human behavior towards mangroves; we need a genuine attitude to preserve the mangroves of Riau Province for the future

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.

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.

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.
绘制海岸线变化图有助于沿海地区的开发和监测。在过去的三十年里，由于人类和自然的干预，位于廖内省东海岸的杜迈市发生了重大而彻底的变化。本研究绘制并测量了30年来杜麦市海岸线的变化率。1990年、1999年、2008年和2020年的Landsat (TM)和OLI (OLI)图像序列成为通过屏幕数字化技术生成海岸线的数据源，然后利用数字海岸线分析系统(DSAS)和地理信息系统研究海岸线的时间行为来描述海岸线的时空变化。结果表明:观测期间海岸线长度为123.14 ~ 125.23 km，平均吸积速率为1.17 m /年，平均磨损速率为2.04 m /年。这些变化速度影响了海岸线向海洋扩展了60,82公顷，侵蚀了76,20公顷的海岸线到陆地。

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.

Leachate, as liquid waste is rich in nutrients, can be used as organic material for the microalgae culture such as Chlorella sp. This study aims to determine the effect of different concentrations to of leachate on the abundance of Chlorella sp populations. The observation was conducted at the laboratory of Microalgae, Agriculture faculty, Islamic University of Riau. The method used in this study was an experimental method using a randomized design; one factor, namely the different concentrations of leachate with five levels, were 5%, 10%, 15%, 20%, and 25%/l of water and three replications. The testing organism in this study was phytoplankton Chlorella sp. The culture container used was a gallon with 20 L of capacity and a water volume of 16 L. The measured parameters were cell abundance, specific growth rate, and water quality. The obtained results showed that the highest abundance of Chlorella sp at a concentration of 25% at 7,322,222 cells/ml, and the peak on day 16, the lowest concentration of 5%, was 2,580,556 cells/ml. On the sixth day, the highest specific growth rate was at a concentration 5% at 0.195/day, and the lowest was 20% at 0.077/day.
