Abstract

Fitoplankton merupakan parameter biologi yang dapat dijadikan sebagai indikator untuk mengevaluasi kualitas dan tingkat kesuburan suatu perairan. Perubahan kualitas perairan sebagai akibat banyaknya beban nutrien yang masuk ke sungai Ciliwung akan berpengaruh terhadap kehidupan fitoplankton. Penelitian ini bertujuan untuk melihat komparasi indeks keanekaragaman (H’) dan Indeks Dominansi (D) fitoplankton di Sungai Ciliwung dari hulu sampai hilir. Penelitian dilaksanakan pada bulan Desember 2016 sampai Februari 2017 dari mulai hulu sampai hilir Sungai Ciliwung. Dari analisis indeks keanekaragaman dan indeks dominansi diperoleh perbedaan yang nyata, dimana semakin ke hilir indeks keanekaragaman (H’) fitoplankton semakin rendah dengan kisaran 1,21 sampai dengan 2,6. Sebaliknya, indeks dominansi menunjukkan hasil bahwa semakin ke Hilir indeks dominasi lebih tinggi dibandingkan dengan bagian hulu dengan kisaran 0,09 sampai dengan 0,68. Dengan demikian indeks keanekaragaman dan indeks dominansi fitoplankton memiliki hubungan berbanding terbalik. Perbedaan indeks keanekaragaman dan indeks dominansi di sepanjang aliran hulu sampai hilir mengakibatkan terjadinya ketidakseimbangan ekosistem di Sungai Ciliwung.  Kata Kunci: Ciliwung, indeks keanekaragaman, Indeks Dominansi, FitoplanktonCOMPARISON OF DIVERSITY INDEX AND DOMINANT INDEX OF PHYTOPLANKTON AT CILIWUNG RIVER JAKARTAABSTRACTPhytoplankton is a biological parameter that can be used as an indicator to evaluate the quality and level of fertility of a water. Changes in water quality as a result of the large load of nutrients entering the Ciliwung River will affect the life of phytoplankton. This study aims to see the comparative index of diversity (H ') and the Dominant Index (D) of phytoplankton in Ciliwung River from upstream to downstream. The study was conducted from December 2016 to February 2017 from upstream to downstream of the Ciliwung River. From the index analysis of diversity and index of dominance, there was a significant difference, where the downward index of diversity (H ') of phytoplankton was lower, ranged between 1,21 and 2,6 (the index of diversity ranging from low to medium).  Otherwise, the dominance index showed the opposite result. The more downstream the dominance index is higher than the upstream, ranged between 0,09 and 0,68. Thus the index of diversity and the index of phytoplankton dominance has a relationship inversely. Differences of diversity index and dominance index in upstream to downstream poses an imbalance of ecosystem in Ciliwung River.Keywords: Ciliwung, diversity index, Dominant Index, Phytoplankton

Abstract

One of the regions in Surabaya which has accumulated the largest pollution levels was the region of Wonorejo. Wonorejo is an area that is used as a mangrove conservation. But, Pb and Cu are heavy metals that have been detected in high concentration in this region. Avicennia alba has been known to have the ability to absorb heavy metals so that mangrove can be used us phytoremediation agent. The purposes of this research were to analyze the concentration of heavy metals (Pb and Cu) in sediments, roots and leaves of Avicennia alba;  to understand the potential of Avicennia alba as an agent of phytoremediation. The result showed that Cu concentration was higher than Pb concentration in sediment, roots and leaves. The concentrations  of Cu were 4.13 ppm - 36.95 ppm and Pb between 3.28 ppm - 23.79 ppm. Based on bioconcentration factor (BCF) Avicennia alba was categorize as excluder (BCF1)  of both heavy metals, but concentration of translocation factor (TF) of Pb was categorized phytoexstraction (TF1) and Cu was categorized phytostabilization (TF1). The result of the BCF and TF showed that Avicennia alba can absorb heavy metals (Pb and Cu) from the environment, however the mobility of the heavy metals in the mangrove will experience different phytoremediation mechanisms (phytostabilization for Cu; phytoexstraction for Pb).POTENTIAL OF AVICENNIA ALBA AS AN AGENT OF PHYTOREMEDIATION HEAVY METAL (PB AND CU) IN WONOREJO, SURABAYAABSTRACTOne of the regions in Surabaya which has accumulated the largest pollution levels was the region of Wonorejo.

Abstract

Bengkoang Island is an unpopulated island in the northern region of the archipelago. The island is divided into 2 zones, Marine Protection Zone and Marine Tourism Utilization Zone, based on the zoning and management plan of the Karimunjawa National Park, Central Java. This research is aimed to observe the condition of the coral reef and coral community fish abundance in Bengkoang Island based on the zoning. There were 2 stations to represent each of the zones at depths of 5 and 10 meters. Line Intercept Transect (LIT) method was used along 100 meters to data the reef substrate and Visual Census method with Belt Transect was used to data the coral community fish. The result showed that the coral cover was the highest in Station 1 at 5 m which was located in the Marine Protection Zone with 80,31%, while the lowest was found in Station 2 at 10 m which was located in the Marine Tourism Utilization Zone with 18,81%. Meanwhile, the coral community fish abudance was the highest in Station 1 at 10 m with 15.600 individual/ha and lowest in Station 2 at 10 m with 4.280 individual/ha. Based on the result, it can be said that the condition of the coral reef ecosystem in Bengkoang Island varies with a high margin between the data stations. The result indicated that the coral reef ecosystem in the Marine Protection Zone was in a better condition than in the Marine Toursim Utilization Zone.DIFFERENCES OF CORAL REEF AND CORAL COMMUNITY FISH ABUNDANCE CONDITION BASED ON ZONING OF BENGKOANG ISLAND, KARIMUNJAWAABSTRACTBengkoang Island is an unpopulated island in the northern region of the archipelago.

Abstract

Biaya operasi kapal yang tinggi merupakan tantangan bagi setiap industri maritim, dalam beberapa studi ditemukan bahwa komponen biaya untuk perawatan kapal mencapai 40% dari keseluruhan biaya operasi kapal, untuk itu diperlukan suatu perbaikan sistem perawatan kapal untuk menekan biaya ini namun tidak mengakibatkan kualitas pelayanan menurun.Sistem Pemeliharaan Kapal Terencana/Planned Maintenance System (SPKT/PMS) adalah suatu sistem yang menyangkut/mengenai rencana-rencana, prosedur-prosedur, dan langkah-langkah untuk mengurangi pemeliharaan tak terduga/darurat (emergency) menjadi sekecil mungkin, sehingga dapat menekan biaya pemeliharaan menjadi sekecil mungkin. SPKT juga merupakan suatu sistem yang akan menolong untuk dapat mengetahui lebih awal kebutuhan-kebutuhan pemeliharaan yang akan datang, mengurangi pemakaian suku cadang (spare parts) dan inventaris (inventory), menghindari pemborosan pemakaian tenaga kerja/jam orang untuk pemeliharaan, menekan waktu dan biaya docking, dan secara umum dapat menghemat biaya pemeliharaan kapal, serta menjamin kondisi teknis kapal sehingga meningkatkan waktu  pengoperasian kapal karena kondisi layak laut kapal yang lebih lama. Pemeliharaan terencana rneliputi pekerjaan pemeliharaan perbaikan (corrective maintenance) dan pekerjaan pemeliharaan pencegahan (preventive maintenance).Standard Operation Procedure Planned Maintenance System yang telah dibuat di desain untuk kegiatan PMS yang bersifat manual, dalam artian menggunakan media form-form berbasis kertas yang harus di-isi secara manual oleh semua entitas sistem PMS. Proses PMS secara manual membuat user harus lebih aktif dalam melakukan isian form yang sudah ada, diantaranya adalah memilah-milah perawatan harian, mingguan, bulanan dan lain sebagainya. Tantangan terbesar implementasi teknologi informasi pada Sistem Pemeliharaan Kapal Terencana adalah bagaimana mentransformasikan SOP yang bersifat manual menjadi berbasis elektronik sehingga meningkatkan kualitas sistem menjadi lebih baik. Jurnal ini menguraikan langkah-langkah implementasi teknologi informasi pada Sistem Pemeliharaan Kapal Terencana mulai dari transformasi SOP, arsitektur jaringan dan metode pelaporanAPPLICATION OF INFORMATION TECHNOLOGY ON PLANNING MAINTENANCE SYSTEMABSTRACTHigh ship operating costs are a challenge for every maritime industry, in some studies it was found that the cost component for ship maintenance reached 40% of the overall operating costs of the ship, for this reason an improvement in ship maintenance systems was needed to reduce these costs but did not result in decreased service quality. Planned Maintenance System / Planned Maintenance System (SPKT / PMS) is a system that involves / plans, procedures, and steps to reduce unexpected maintenance / emergency (emergency) to be as small as possible, so as to reduce costs maintenance becomes as small as possible. SPKT is also a system that will help to be able to know in advance the future maintenance needs, reduce the use of spare parts (inventory) and inventory (inventory), avoid waste of labor / person hours for maintenance, reduce time and costs docking, and in general can save ship maintenance costs, as well as guarantee the technical conditions of the ship so as to increase ship operating time due to longer ship seaworthy conditions. Planned maintenance includes corrective maintenance work and preventive maintenance work. The Standard Operation Procedure Planned Maintenance System has been designed for manual PMS activities, in the sense of using paper-based media forms that must be filled manually by all PMS system entities. The PMS process manually requires the user to be more active in filling in existing forms, including sorting out daily, weekly, monthly treatments and so on. The biggest challenge in the implementation of information technology in the Planned Ship Maintenance System is how to transform SOPs that are manual into electronic-based so as to improve the quality of the system for the better. This journal describes the steps of implementing information technology in the Planned Ship Maintenance System starting from SOP transformation, network architecture and reporting methodsKeywords: Planned Maintenance Maintenance System, Planned Maintenance System, Standard Operation Procedure, vessel operation

Metode pengambilan data pasang surut menggunakan metode Tide Pole yaitu pengukuran menggunakan rambu ukur. Metode pengambilan data arus laut menggunakan metode Float Tracking yang merupakan metode Lagrangian yaitu mengukur menggunakan benda apung ke laut kemudian diukur jarak dan perpindahannya. Metode pengambilan data gelombang menggunakan metode Wave Pole yaitu mengukur tinggi gelombang. Hasil dari pengolahan data tersebut berupa peta dan informasi tentang kondisi hidro oseanografi.Kata Kunci : Hidro-Oseanografi, Pasang Surut, Arus, Gelombang.HYDRO-OCEANOGRAPHIC CONDITION (TIDES, CURRENTS AND WAVES) OF NONGSA BATAM WATERSABSTRACTTanjung Bemban is one of the waters located in Nongsa district, Batam. This research is needed for knowing the hydro-oceanography component of the tides, currents and waves. Tidal measurements were obtained by the semi-diurnal tidal type with the highest tide of 260 cm and the lowest retrograde of 19 cm with observation for 4 days and the interval for 15 minutes. Measurement of ocean currents is done at 30 second intervals, the current velocity in Tanjung Bemban waters ranges from 0.26 m / s up to 0.02 m / s. Wave measurements are made by measuring the wave height, so that the wave heights range from 18 cm to 21 cm. Tides data retrieval method using Tide Pole method is measurement using measuring beam. Method of taking data of ocean current using Float Tracking method which is Lagrangian method that is measuring using floating object to sea then measured distance and its displacement. Waves data collection method using Wave Pole method is measuring wave height. The results of data processing in the form of maps and information about the condition of hydrooceanography.Keyword: Hydro-Oceanographic, Tidal, Current, Wave.
