Abstract

ABSTRAK Tuna mata besar (Thunnus obesus) di Samudera Hindia menjadi salah satu target utama penangkapan. Berdasarkan pemanfaatan tersebut, perlu dilakukan penelitian mengenai parameter populasi tuna mata besar. Penelitian ini bertujuan untuk mengetahui aspek pertumbuhan, ukuran pertama kali tertangkap, parameter populasi, laju mortalitas, laju eksploitasi dan pola rekrutmen. Jumlah sampel tuna mata besar sebanyak 648 ekor diambil dari 21 armada rawai tuna (longline) yang melakukan bongkar selama penelitian. Data panjang tahun 2013-2014 diperoleh dari Loka Penelitian Perikanan Tuna Bali. Penelitian ini dilakukan bulan April-Mei 2016 di Pelabuhan Benoa, Denpasar, Bali. Analisis data menggunakan Model Von Bertalanffy Growth Function dengan software FISAT II. Hasil penelitian menunjukkan pola pertumbuhan bersifat allometrik negatif. Faktor kondisi diperoleh sebesar 1,02-1,27. Ukuran pertama kali tertangkap (L50%) sebesar 126,54 cmFL. Persamaan pertumbuhan Von Bertalanffy Growth Function (VBGF) diperoleh Lt=199,5(1 - e 0,22 (t+0,451)), dengan nilai K= 0,22/tahun, nilai t0= -0,451 tahun dan L∞ = 199,5 cmFL. Laju mortalitas penangkapan (F) = 0,51/tahun, lebih besar daripada mortalitas alami (M) = 0,40/tahun, berarti kematian tuna mata besar lebih banyak disebabkan karena faktor eksploitasi/penangkapan. Laju eksploitasi (E)= 0,56 mengindikasikan tuna mata besar yang tertangkap oleh armada rawai tuna (longline) di Samudera Hindia dalam kondisi fully exploited (padat tangkap).Kata Kunci : Ikan tuna mata besar; aspek biologi; umur; pertumbuhan; mortalitas; laju eksploitasi; rekrutmen; Samudera Hindia  ABSTRACT Bigeye tuna (Thunnus obesus) in the Indian Ocean became one of the main targets of arrest. Based on utilization, research is needed on bigeye tuna population parameters. This study aims to determine of growth, size at the first caught, population parameters, mortality rate, exploitation rate and recruitment patterns. Number samples of bigeye tuna were taken from 648 fishes by 21 tuna longline fleets which was unloading during this study. Length data of 2013-2014 were obtained from Research Institute for Tuna Fisheries, Bali. This research was conducted April-May 2016 in Benoa Harbour, Denpasar, Bali. Data analysis used the Von Bertalanffy Growth Function Model with FISAT II software. The results showed negative allometric growth patterns. The condition factor was obtained for 1.02 to 1.27. The length at first caught (L50%) amounted to 126.54 cmFL. VBGF growth equation was obtained Lt=199.5(1 - e 0.22 (t + 0.451)), with the value K=0,22/year, t0= -0,451/year and L∞= 199,5 cmFL. The fishing mortality rate (F)= 0.51/year, it was bigger than the natural mortality (M)= 0.40/year, means that mostly mortality of bigeye tuna was caused by the exploitation / fishing factor. The exploitation rate (E)= 0.56, indicated that bigeye tuna were caught by tuna longline fleets in the Indian Ocean on fully exploited.Keywords:Bigeye tuna; biology aspect; age; growth; mortality; exploitation rate; recruitment; Indian Ocean

Abstract

ABSTRAK Hasil tangkapan rawai tuna terdiri dari dua jenis yaitu hasil tangkapan utama (target species) dan hasil tangkapan sampingan (by catch). Penelitian ini bertujuan untuk mendapatkan informasi jenis ikan hasil tangkapan utama dan ikan hasil tangkapan sampingan rawai tuna, menghitung komposisi ikan, menganalisa distribusi ukuran ikan dan mengetahui nilai CPUE ikan HTU dan ikan HTS. Penelitian dilaksanakan pada bulan April-Mei 2016 dengan mengikuti kegiatan sampling enumerator Loka Penelitian Perikanan Tuna Benoa, Bali. Hasil penelitian menunjukkan jenis ikan hasil tangkapan utama rawai tuna yaitu ikan Tuna mata besar (Thunnus obesus), Tuna sirip kuning (Thunnus albacares), Tuna sirip biru selatan (Thunnus maccoyii) dan Tuna albakora (Thunnus allalunga). Jenis ikan hasil tangkapan sampingan rawai tuna yang mendominasi yaitu ikan opah (Lampris guttatus), hiu air (Prionace glauca) dan escolar (Lepidocybium flavobrunneum). Perbandingan komposisi ikan hasil tangkapan utama yaitu 69% dan ikan by catch 31%. Distribusi ukuran ikan hasil tangkapan sampingan sebagian besar sudah memenuhi kriteria ikan layak tangkap. CPUE ikan hasil tangkapan sampingan lebih rendah dibandingkan dengan ikan hasil tangkapan utama. Kata kunci: Hasil Tangkapan Sampingan (by catch), Rawai Tuna, Pelabuhan Benoa Bali, Samudera Hndia.  ABSTRACT Catch of Tuna longline has two types, that is target species and by catch product.

Abstract

Fake news is a major challenge in modern journalism in this digital era. Although mainstream media have strict journalistic standards, they can inadvertently popularize fake news. Mainstream media can also increase public exposure to fake news through moral efforts to correct incorrect reporting. This article highlights fake news mitigation practices in Indonesian mainstream media through a literature review approach of previous research and direct observation of eight online news media: detiknews, kompas.com, liputan6.com, okezone, republika, sindonews, tempo.co, and tribunnews.com. The results of the study show that online media are aware of the importance of maintaining credibility amidst the rapid flow of digital information, the balance between meeting readers' information needs instantly and maintaining news credibility, media awareness of the importance of digital literacy among the public, and the importance of maintaining morality amidst online media competition. Several suggestions are given so that mainstream media are better able to improve their quality by reporting high-quality news and preventing fake news from spreading in the community.

Abstract

This research discusses research that focuses on the capabilities of satellitebased LoRa, for satellite positions orbiting in low earth orbit (LEO). The expectation of low power wide area network (LPWAN) satellite can find the quality of transmitting data using LoRaWAN which is part of LPWAN and can provide quality of service (QoS) with high-quality real-time sensor data, low latency, long-range, low-power, no attenuation signal, no problem with obstacles in terrestrial areas, and other benefits that can be widely optimized. This article uses a comprehensive analysis of mathematical calculations as well as precise and accurate simulations for the actual development of satellite-based LPWAN. The satellite-based IoT is unlimited in terms of distance, to provide good services to all IoT users in the world. The comparison with terrestrial measurements is analyzed in detail, especially the signal attenuation factor that causes a lot of signal loss and data is not well received. Several methods are used to help reduce collision data, such as adaptive data rate (ADR) which can reduce collisions by 30%.
