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

This study explores the role of indigenous ecological narratives in shaping sustainable environmental practices through an ecosemiotic-cultural perspective. By employing a retro-prospective analysis, the research examines traditional ecological knowledge embedded in Indonesian literary texts, revealing how past wisdom informs contemporary and future environmental consciousness. The primary data for this research comprises three contemporary Indonesian novels that encapsulate indigenous ecological wisdom and human-nature relationships: Mata dan Manusia Laut (2019) by Okky Madasari, Tanjung Kemarau (2020) by Royyan Julian, Sanggarguri (2021) by Lalu Agus Fathurrahman. The findings demonstrate that indigenous narratives function as semiotic systems that encode ecological values, communal responsibility, and harmonious relationships with nature. Through cultural symbols, myths, and folklore, these narratives offer sustainable models of environmental stewardship rooted in collective memory and local traditions. The study also highlights the potential of integrating these narratives into modern sustainability policies and education, ensuring their relevance in addressing contemporary ecological challenges. By bridging historical ecological wisdom with future sustainability efforts, this research contributes to the broader discourse on ecosemiotics and sustainable development. The implications of this study underscore the significance of interdisciplinary approaches in preserving cultural heritage while fostering environmental resilience.

Artikel ini membahas tentang bahasa Presiden Joko Widodo selama pandemi Covid-19. Kami mencoba menyoroti bagaimana seorang pemimpin negara mengkonstruksi bahasa guna menciptakan kedamaian dan ketenangan pada masyarakat di tengah kepanikan akibat pandemi Covid-19. Data penelitian ini berasal dari akun Youtube Sekretariat Negara berjudul Penjelasan Presiden Joko Widodo Terkait Larangan Mudik (rilis 16 April 2021). Studi ini menyelidiki bahasa berdasarkan model metadiscourse Hyland. Hasil penelitian menunjukkan bahwa frekuensi transisi paling tinggi diikuti self-mentions.Penyebutan self-mentions menjadi titik penting dalam metadiscourse Presiden Joko Widodo terkait dengan unsur politik dan mengelolah emosi. Ini mengindikasikan bahwa Presiden Joko Widodo menarik simpati melalui ajakan secara bersama-sama untuk menjaga kondusivitas daerah akibat Covid. Presiden Joko Widodo juga seolah-olah menunjukkan kehadirannya melalui perasaan yang sama seperti yang dialami masyarakat. Bahasa-bahasa ini berkorelasi dengan aspek kebahagiaan, kesejahteraan, dan memuat unsur politis guna memberikan ketenangan. Meskipun aspek tersebut guna meredam sisi emosi dan stress yang dialami masyarakat.
