Abstract

Abstract. Lombok Strait is one part of Indonesia Through Flow (ITF), important for national and international maritime economic. The strait is passed by ITF, i.e., a displacement water from the Pacific Ocean into the Indian Ocean caused by a difference in the sea water level. ITF flows across the Makassar Strait to south direction and passes through the smaller straits along Bali to Flores. ITF pattern is influenced by its local area condition which creates unique characteristics in each place. ITF passes through the Lombok Strait in part directly related to the Indian Ocean, as well as a very diverse state bathymetry of shallow ocean to ocean trenches. Various oceanographic phenomena affect ITF in the Lombok Strait: tides and waves are formed due to the interaction between the ocean currents from the Indian Ocean to the Lombok Strait, met with ITF flowing from the Lombok Strait into the Indian Ocean. As tides, currents are influenced by the tides that have harmonic components, but there are differences in the frequency and phase are formed. Harmonic component is one of indicators in determining the characteristics of a body of water. The purpose of this study is to obtain the derived harmonic components by analysing currents data in the Lombok Strait acquired from The International Nusantara Stratification and Transport (INSTANT) Expedition Mooring Deployment 1 conducted in 2004 to 2005. Based on the analysis it is known that the characteristic harmonic currents in the Lombok Strait is influenced by significant harmonic components such as Solar Semi Annual (SSA) and Solar Annual (SA)constituents be used, as the result of harmonic analyses of tidal data at ports all over the world reveal that they are dominated by the seasonal variations of sun.Keywords : ITF; Sea Current; Harmonic Component; INSTANT ExpeditionAbstrak. Selat Lombok merupakan salah satu alur lintas kepulauan Indonesia (ALKI) yang penting bagi perekonomian maritim nasional dan internasional, sekaligus sebagai alur dari arus lintas Indonesia (Arlindo). Arlindo merupakan peristiwa perpindahan masa air dari Samudera Pasifik menuju Samudera Hindia, yang disebabkan oleh perbedaan ketinggian air laut. Jalur Arlindo melintasi Selat Makasar menuju selatan, kemudian terbagi melewati selat-selat yang lebih kecil diperairan Bali hingga Nusa Tenggara Timur. Pola Arlindo dipengaruhi keadaan perairan setempat yang dilewatinya, sehingga Arlindo memiliki karakteristik yang unik pada masing-masing tempat. Pada Selat Lombok yang berhubungan langsung dengan Samudera Hindia,  fenomena oseanografi mempengaruhi ARLINDO di Selat Lombok diantaranya adalah pasang surut dan internal wave yang terbentuk karena interaksi antara arus laut dalam yang berasal dari Samudera Hindia menuju Selat Lombok. Arus pasut memiliki komponen harmonik seperti gaya pembangkitnya, namun terdapat perbedaan pada frekuensi dan fasa yang terbentuk. Komponen harmonik pasut dan arus pasut merupakan salah satu indikator dalam penentuan karakteristik suatu perairan. Tujuan dari penelitian ini adalah untuk memperoleh besaran komponen harmonik yang diturunkan dari arus di Selat Lombok dari Ekspedisi INSTANT Mooring Deployment 1 yang dilaksanakan pada tahun 2004 hingga 2005. Berdasarkan analisis harmonik diketahui bahwa karakteristik arus di Selat Lombok dipengaruhi oleh komponen harmonik signifikan seperti Solar Semi Annual dan Solar Annual yang merupakan komponen yang dipengaruhi oleh pergerakan matahari secara paruh tahun maupun tahunan.Kata kunci : Arlindo; Arus Laut; Komponen Harmonik; Ekspedisi INSTANT

Abstract

One effort to reduce bycatch in togok is to modify the togok by creating a vent to reduce bycatch by BRD. The BRD installed on the togok was a rope BRD vent made of Polyethelene (PE) with a diameter of 2 mm. The rope BRD vent is attached to the top of the cod-end as an escape vent 25 x 50 cm. The escape vent and the stash cod-end are covered with a net with a mesh size of 5 mm. The cover net aims to collect data on fish catches that pass through the rope BRD vent. The percentage of fish that pass through the rope BRD vent can be calculated, and measure the size of the fish caught in the cod-end and covered as an indicator of the effectiveness of the rope BRD vent on togok. This experiment was carried out for 20 days of fishing operation and 40 hauls. The results showed that the catch of togok without rope BRD vent (conventional) and togok with modified rope BRD vent were different (p 0.05), where the catch of conventional togok was 468.34 kg, and the catch of modified togok was 305.235 kg. The fishing catches in the cod end and cover sections the most are bycatch with 51% and 54% of the percentage of the total catch, and the least in the cod end is the discarded catch, which is 21% of the percentage of the total catch and on the cover is the main catch (main catch) with 19% of the percentage of the total catch.The average size of the catch of togok species of fish is there are many immature sizes, and the average size of the catch of togok species of shrimp is there are in maturity size.Keywords:BycatchBycatch excluder device (BRD)DiscardMain catch

Abstract

The waters of the Mamberamo watershed are around 7.7 million hectares. Some territorial waters are surrounded by jungles that are rich in unique biodiversity. Diverse biodiversity must be accompanied by a state of good water quality. So that the monitoring of water quality is very good in terms of physical and chemical physics parameters. Monitoring using chemical physics parameters has been widely used, but using aquatic biota is still rare, so it is expected to be more assertive in exposing the state of river damage. Aquatic biota used is periphyton. Periphyton has the potential to be a study of ecological indicators, a major producer in the food chain and its inherent nature in aquatic substrates. The purpose of this study was to determine the diversity of the periphyton community, determine the quality of waters in terms of chemical physics in the Mamberamo watershed and see the relationship between the two parameters. The method of determining the location was purposive sampling with descriptive analysis of the correlation results. Field observations and sampling were carried out on three tributaries and ponds in the form of flood-exposed lakes in the Membramo watershed in February, May, August and October 2016. The results showed the highest periphyton composition of Bacillariophyceae class followed by Chlorophyceae and Cyanophyceae. The diversity value of the Mamberamo river is 1 H '= 3 which indicates moderate diversity, and the dominance index value ranges from 0.15 to 0.45, which indicates that there is no species that dominates in the waters of the Mamberamo River. Based on the results of the water quality assessment in the presence of periphyton and the physical chemistry characteristics of the water, it is found that the criteria for river water quality are classified as good and not polluted.Keywords:Ecological indicatorsChemical physics characteristicsPeriphytonMamberamo RiverPapuaABSTRAKLuas perairan DAS Mamberamo berkisar 7,7 juta hektar. Sebagian wilayah perairan dikeliling oleh hutan rimba yang kaya akan keanekaragaman hayati yang unik. Keanekaragaman hayati yang beragam harus disertai keadaan kualitas air yang baik. Sehingga pemantauan kualitas perairan sangat perlu baik ditinjau dari parameter fisika kimia dan biologi. Pemantauan menggunakan parameter fisika kimia telah banyak digunakan, tetapi menggunakan biota perairan masih jarang ,sehingga diharapkan dapat lebih tegas dalam mengekspresikan keadaan kerusakan sungai. Biota perairan yang digunakan dalam penelitian ini adalah perifiton. Perifiton berpotensi sebagai kajian indikator ekologis, produsen utama dalam rantai makanan serta sifatnya yang menempel di substrat perairan. Tujuan penelitian ini adalah untuk mengetahui keragaman komunitas perifiton, mengetahui kualitas perairan dari segi fisika kimia di DAS Mamberamo serta melihat hubungan antara kedua parameter tersebut. Metode penentuan lokasi purposive sampling dengan analisis deskripitif dari hasil korelasi. Pengamatan lapangan dan pengambilan sampel dilakukan pada tiga aliran anak sungai dan telaga yang berupa danau paparan banjir di DAS Membramo pada Februari, Mei, Agustus dan Oktober 2016. Hasil penelitian menunjukkan komposisi perifiton tertinggi kelas Bacillariophyceae diikuti Chlorophyceae dan Cyanophyceae. Nilai keanekaragaman sungai Mamberamo adalah 1H’=3 yang menyatakan keanekaragaman sedang, dan nilai indeks dominasi berkisar 0,15-0,45 yang menandakan bahwa tidak ada jenis yang mendominasi di perairan Sungai Mamberamo. Berdasarkan hasil penilaian kualitas air secara keberadaan perifiton dan karakteristik fisika kimia air maka didapat kriteria kualitas perairan sungai yang tergolong bagus dan belum tercemar.Kata kunci:Indikator ekologisKarakteristik fisika kimiaPerifitonSungai MamberamoPapua
