Road safety is a topic that came out over the years and has now become a worldwideproblem. This can be picked up with the founding of the Decade of Action for Road Safety 2010-2020 by the United Nations. Efforts of prevention road safety during the implementation of roadimprovement has been specified in the path of contract execution. However, assessment of safetyaudits in the work zone on the road improvements has not been studied. Descriptive method used toidentify related attributes of safety in the work zone. Hierarchy and the weighting of each attribute isused the Analytical Hierarchy Process (AHP) method. The results obtained in, the weighting of the 4criteria division of work zones in sequence from the weight of greater are: the work zone; closerszone; initial taper zone and end taper zone by weight are: 59%; 27%; 9% and 6%. Weight rating ofalternative attributes for closers zone criteria is: road work warning signs: lane usage instructionssigns; closers zone distance; narrowing of lanes of the road warning signs and speed limit warningsigns, with their respective weights are: 46%; 23%; 15%; 11%; 5%. Weight rating attributesalternative to early taper zone criteria are: the installation of cone/guardrail; reflector at the initial ofthe work zone; minimum taper length requirement with respective weights: 53%; 30%; 17%.Assessment criteria attribute for the work zone are: minimum length of the work zone; the minimalwidth of the work zone; installation cone/guardrail; and the minimum distance between work zones,with respective weights: 70%; 15%; 9%; 6%. And the weight of attribute ratings for end zonecriteria is: the installation of cone/guardrail and followed with a minimum length end taperrequirements, with respective weights: 82%; 18%. Abstrak: Keselamatan Jalan merupakan isu yang mengemuka dari tahun ke tahun dan saat ini sudahmenjadi permasalahan global. Hal ini dapat dilihat dengan dicanangkannya Decade of Action forRoad Safety 2010-2020 oleh Perserikatan Bangsa Bangsa. Upaya pencegahan keselamatan dijalanselama masa pelaksanaan peningkatan jalan telah diatur dalam kontrak pelaksanaan jalan. Namuncara penilaian pemeriksaan keselamatan di jalan pada zona kerja pelaksanaan peningkatan jalanbelum diteliti. Metode deskriptif digunakan untuk mengidentifikasi atribut terkait aspek keselamatandi zona kerja pekerjaan jalan. Hirarki dan pembobotan penilaian masing masing atributmenggunakan metode Proses Hirarki Analitikal (PHA). Hasil rancangan pembobotan pada levelkreteria medapatkan 4 kreteria pembagian zona kerja secara teurut dari bobot kepentingan yanglebih besar adalah zona kerja; zona pendekat; zona taper awal dan zona taper akhir dengan bobotadalah 59%; 27%; 9% dan 6%. Bobot penilaian atribut alternative untuk kreteria zona pendekatadalah: rambu peringatan ada pekerjaan jalan; rambu petunjuk penggunaan lajur; jarak zonapendekat; rambu peringatan penyempitan lajur jalan dan rambu peringatan batas kecepatan, denganbobot masing-masing adalah: 46%; 23%; 15%; 11%; 5%. Bobot penilaian atribut alternative untukkreteria zona taper awal adalah: pemasangan kerucut/guardrail; pemasangan reflector padapertemuan taper awal dengan zona kerja; persyaratan panjang taper minimum dengan bobot masingmasing:53%; 30%; 17%. Penilaian atribut untuk kreteria zona kerja adalah: panjang zona kerjaminimum: lebar zona kerja minimum; pemasangan kerucut/guardrail; dan jarak antar zona kerjaminimum, dengan bobot masing-masing: 70%; 15%; 9%; 6%. Dan bobot penilaian atribut untukkreteria zona penjauh adalah: pemasangan kerucut/guardrail dan diikuti dengan persyaratanpanjang taper akhir minimum, dengan bobot masing-masing: 82%; 18%.Kata kunci: keselamtan, metode PHA, zona kerja, peningkatan jalan

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. Batam City, Riau Islands.

Anchovies (Stolephorus sp), need to be managed well because although as a natural resource that is open access if not managed properly, the management of fishery resources is not optimal and sustainable. One approach in the management of fish resources is with a surplus production model. The analysis was conducted to obtain the best model that aims to know the maximum sustainable catch (MSY), utilization rate, and use of anchovies. Data on catches and anchovies fishing efforts were collected from the Siak District Fisheries and Livestock Service. The best Surplus Production Model used to assess the potential of anchovies is the Walter-Hilborn model. Optimal effort (EMSY) of 150 Units per year. Cmsy's optimal catch is 247.75 tons per year. The utilization rate for 2020 is 70%, with an entrepreneurial rate of 41%, which indicates that overfishing has not occurred both biologically and economically.

CV Poetra Mandiri Karton is a company that has not been able to meet production target each day. Based on preliminary analysis, production underproduction was due to workers’ fatigue caused by manual material handling activities in the entire production process. To solve these problems, nordic body map (NBM) approach was applied. Prior to work, workers experienced musculoskeletal fatigue at down waist, and they experienced musculoskeletal fatigue at up waist, left forearm, right forearm, left hand, right hand, left ankle, and right ankle after work. Based on questionnaire of National Aeronautics and Space Administration Task Load Index (NASA-TLX), average of mental workload from all three groups is quite heavy. By using rapid entire body assessment (REBA), it is found that average value of the risk in group 1 and group 2 requires immediate action, whereas action is required by the third group. This article also presents a trolley design that will be used in manual material handling activities.
