    Background and Purpose: The large number of shipyard industrial activities that stand around Buluh Island has the potential to pollute the waters of the island of Buluh so that it impacts on the catches of the reed island fishermen themselves. Some electronic media reported the impact felt by the fishermen of Buluh Island on the shipyard industry and farm of pig activities. This study aims to maintain the quality of the aquatic environment on Batam City's Buluh Island through the modeling of sources of scattered waste, so a study of non-point pollution is needed that has a direct impact on people's lives. Material and Methods: BOD parameters, in general are widely used to determine the level of waste water pollution. BOD measurement is a measurement of the amount of oxygen used by microorganisms in decomposing organic matter that is in a waters. Decomposition of organic matter involves various organisms and oxidation reactions occur with the end result of carbon dioxide (CO2) and water (H2O). Oxidation reactions during the BOD examination are the result of biological activity and the reactions that take place are influenced by the population and temperature. This research was conducted in the Buluh Island area, Bulang District, Batam City, Riau Islands Province. This research was conducted in April - June 2019. The location of the study was Buluh Island, where there were many shipyards and pigs which were thought to be a source of waste distributed in the marine waters of the island of Batam City. Sampling is done based on the station (5 stations) that have been determined and measured in the laboratory and compared with the results of the model using equation 1. Results: Based on the results obtained at the five stations both for measurement results and modeling results (calculation results) BOD concentration values the highest is at station-3 and station-5 with values 16,978 and mg / L.17, 986 mg / L. This is because the station is the main source of waste in the farm of pigs and the location of the largest shipyard in the study area which has an impact on the decline in catches of Batam Island's Buluh fishermen. Conclusion: Based on the analysis conducted in this study, it can be concluded that by using the equation of the distribution model of scattered limbs and some physical parameters such as current speed, distance, coordinates and some water samples at each station, it is very easy to map the BOD-wide waste distribution model in Buluh Island waters.

    Model Distribusi Limbah Nitrit (No2-N) Terhadap Kualitas Air Bawah Tanah Di Kota Pekanbaru
    (2018-03-12) Syahril, Syahril; Sukendi, Sukendi; Zulkarnain, Zulkarnain; Juandi, Muhammad
    Background and Objective: Nitrite waste is an important factor in determining the sustainability of underground water quality that can be associated with the value of nitrite concentration based on the water quality standard. This study aims to determine the distribution of nitrite waste in the lithology of the study area. Materials and Methods: This study was conducted using experimental methods. These measurements use equipment that suits the needs of pizometers, geoelectric equipment, GPS. The data obtained are data ratio such as hydraulic conductivity data, well depth, well position, nitrite concentration and coordinate of research location. Contour distribution model of nitrite waste in lithology using Surfer-13 software. Results and Discussion: Nitrite concentrations obtained through existing wells in community settlements ranged from 0.005 mg / L to 0.09 mg / L. While for class I, II and III is 0.06 mg / L while class IV is not required. This concentration value is actually a value derived from the accumulation of all sources of pollutants that exist in the city of Pekanberu, therefore this research is included in the research source of pollution spread (Nonpoint Source Polutan). Conclusion: The highest nitrite concentration values were in Rumbai, Rumbai Pesisir, Sail and Tenayan Raya sub-districts with an average of 0.08 mg / L, while the lowest was Marpoyan Damai and Tampan sub-district with an average of 0.014 mg / L. Although this concentration value ranges from 0.08 mg / L which exceeds the water quality standard for each class of 0.06 mg / L, it is still less than 1 mg / L and is suitable for community use.

    STRATEGI PENGELOLAAN PENGGUNAAN ALAT PELINDUNG DIRI (APD) DI LABORATORIUM KLINIK KOTA PEKANBARU
    (Program Doktor Ilmu Lingkungan UNRI, 2019-11-16) Yulianti, Fepy; Siregar, Yusni Ikhwan; Syahril, Syahril
    The number of work accidents in Indonesia tends to increase. There were 157.313 cases of work accidents during 2018. The laboratory is a workplace that has many potential hazards such as spills, chemical explosive reactions, punctured needles, exposure to infectious material. Workers in the laboratory are required to use the appropiate PPE, which is a lab coat, shoes, masks and gloves. Managers must provide proper PPE at work. Ineffective use, leads a problem that arises in the field. Management strategies for utilizing appropriate PPE usage are needed to improve the health status of workers. Percentage of clinical laboratory workers in Pekanbaru City who have knowledge based on STR ownership (68.61%) and the availability of work guidelines in the form of SOP (65%), which classified as the quite good category. The practice of PPE usege and the role of managers in managing, supplying, procuring and number of PPE is also classified as good category. Waste management in the laboratory uses a third party. Policy in the form of rewards (35%), administration of decrees/ sanctions (55%), availability of PPE signs / symbols (30%), providing training to each officer (40%) and providing health insurance in the form of MCU (50%) and vaccination (10%) is classified as poor category. Determination of management strategies for the use of PPE in the Pekanbaru clinical laboratory in this study using the SWOT calculation. The right strategy used from the results of the SWOT calculation is the survival strategy. The disadvantage is that there are no signs / symbols of PPE guidelines when entering the laboratory and the threat is that PPE waste that has been used without being managed properly according to B3 waste regulations will contaminate the environment.

    Valuasi Ekonomi Pengelolaan Usaha Panglong Arang Berkelanjutan Di Desa Jangkang Kabupaten Bengkalis
    (wahyu sari yeni, 2019-01-10) Nurliah, Nurliah; Genta, Muhammad; Syahril, Syahril
    Background and Objectives: Mangroves are very productive ecosystems. Various products from mangroves can be produced either directly or indirectly, including: fuel wood, building materials, household needs, paper, leather, medicine and fisheries. Material and Methods: Mangrove ecosystems are a system in nature where life takes place that reflects the reciprocal relationship between living things and their environment and between living things themselves, found in coastal areas, affected by tides and dominated by species of trees or shrubs that typical and capable of growing in salty / brackish waters. Economic valuation in this study consisted of the sorting of mangroves (Rhizophora apiculata), the amount of raw material per furnace, the amount of wet raw material, rendeman of raw materials, the amount of clean charcoal, charcoal prices per kilo, income per furnace. The economic value obtained can use equation 1. Results: The time needed to complete the manufacture of charcoal ± 2 months so that the average wage to be paid to the panglong charcoal workers for one person is between Rp. 600,000, - Rp. 800,000 / kitchen (as long as it becomes charcoal). Charcoal produced for the capacity of 2-3 tons of wet mangrove is 2837.5 kg (20% yield) so that 1 panglong of charcoal produces 2270 kg (1 average length is 2-3 tons) for small plants, where the price per kilogram of charcoal is sold by long-term owners is Rp. 3,000, - / kg, the total income of the landlord is Rp. 6,810,000.00, - / panglong / production. Conclusion: If every 1 kg of mangrove wood is valued at Rp. 120 - Rp. 180, the business owner spends Rp.480,000 - Rp. 600,000 / day or Rp. 14,400,000 - 18,000,000 / month so that every day every worker only earns Rp. 60,000, even though the Regional Government of Bengkalis Regency has determined the District Minimum Wage (UMK) of Rp. 2,250,000 / month.
