Abstract

Benih ikan baramundi Lates calcarifer diperoleh dari pemijahan alami dengan jumlah induk terbatas sehingga variabilitas pertumbuhan dan kelangsungan hidup antar-batch menjadi tinggi. Penelitian dilakukan untuk menganalisis pertumbuhan dan mengevaluasi variasi genetik ikan kakap putih populasi Australia, Situbondo dan Lampung hasil domestikasi dan dibudidaya di hatcheri skala rumah tangga (HSRT). Sebanyak 10 ekor ikan barramundi dari setiap populasi digunakan untuk analisis variabilitas genetik dengan dua lokus mikrosatelit, yaitu Lca21 dan Lca32. Selanjutnya, data mikrosatelit diolah menggunakan software genetic analysis in excel (GenAlEx 6.51b2). Hasil yang diperoleh menunjukkan bahwa pertumbuhan panjang dan bobot tubuh serta laju pertumbuhan spesifik ikan baramundi dari Australia lebih tinggi dibandingkan dari Situbondo dan Lampung (P<0,05); sedangkan ikan baramundi dari Situbondo dengan Lampung adalah sama (P>0,05). Jumlah alel setiap lokus ikan baramundi berkisar 2-8 alel dan heterozigositas tertinggi dimiliki oleh ikan barramundi asal Situbondo (0,85), diikuti Lampung (0,65) dan paling rendah dari Australia (0,54). Dari hasil riset tersebut dapat disimpulkan bahwa ketiga populasi ikan baramundi hasil domestikasi dan dipeliharan dalam sistem HSRT memenuhi kelayakan untuk digunakan untuk kegiatan hibridisasi atau membentuk populasi awal (sintetis). Barramundi seeds, Lates calcarifer are usually sourced from natural spawning using a limited number of broodstock. Therefore, the growth and survival rate of these seeds vary greatly between batches. The research was performed to determine the growth pattern and genetic variations of barramundi seed populations produced from domesticated broodstock sourced from Australia, Situbondo, and Lampung and reared in small-scale hatcheries. Ten individuals of barramundi from each population were used for microsatellite analysis using two microsatellite loci, namely: Lca 21 and Lca 32. The resulted microsatellite data was processed using the genetic analysis available in Excel software (GenAlEx 6.51b2). The results showed that the growth in length and body weight as well as the specific growth rate of barramundi seeds produced from Australia broodstock were higher than that of Situbondo and Lampung (P<0.05) while the later two were similar (P>0.05). The number of microsatellite alleles ranged from 2-8 and the highest heterozygosity was obtained by barramundi seeds produced by Situbondo (0.85), followed by Lampung (0.65), dan Australia (0.54) broodstock. From the results of the research, it can be concluded that the three populations of barramundi fish, which were domesticated and reared in the HSRT system, meet the criteria for use in hybridization program or for forming a synthetic population.

Abstract

This study investigates the dynamic interplay between ethical Leadership, sleep quality, and employee service innovation behavior within organizational contexts. Employing a dual-path model analysis, we explore how ethical leadership practices influence service innovation and how sleep quality moderates this relationship. The research in diverse industries integrates quantitative survey data and draws upon organizational behavior theories to unravel the intricate dynamics shaping contemporary workplace environments. Anticipated findings reveal a substantial positive correlation (approximately 85%) between ethical Leadership and service innovation. Additionally, the study uncovers the nuanced conditions under which sleep quality amplifies or diminishes the positive effects of ethical Leadership on employee service innovation behavior. This research contributes theoretical advancements to dual-path models and offers practical implications for organizational strategies, emphasizing ethical leadership development and sleep quality improvement. Future research directions include longitudinal exploration, cross-cultural analyses, and intervention studies, while ethical considerations prioritize participant well-being and informed consent.

Abstract

Keracunan ciguatera mempunyai dampak yang signifikan, memengaruhi kesehatan fisik individu, dan memberikan pengaruh terhadap kesejahteraan ekonomi dan sosial penduduk yang tinggal di daerah yang terkena dampak. Tujuan dari penelitian ini adalah untuk mengevaluasi tingkat literasi masyarakat pesisir di Gili Matra, Indonesia, sehubungan dengan pemahaman mereka tentang fenomena Ciguatera dan potensi dampaknya terhadap kegiatan ekonomi lokal. Melalui penggunaan pendekatan penelitian kualitatif, penelitian ini menemukan bahwa sebagian besar penduduk yang tinggal di kawasan pesisir Gili Matra memiliki pemahaman yang terbatas terhadap fenomena Ciguatera. Meskipun dampak ekonomi langsung terhadap masyarakat lokal mungkin terbatas, namun penting untuk mengedukasi masyarakat mengenai fenomena ini guna meningkatkan kesadaran masyarakat, khususnya dalam hal pencegahan terjadinya keracunan ciguatera.   Abstract Ciguatera poisoning has significant implications, affecting both the physical health of individuals and exerting influence on the economic and social well-being of populations living in affected areas. This study aims to evaluate the level of literacy proficiency among coastal populations in Gili Matra, Indonesia, in connection to their understanding of the Ciguatera phenomena and its potential impact on local economic activities. Through the utilization of a qualitative research approach, the present study discovered that a significant proportion of residents living in the coastal area of Gili Matra had a restricted understanding of the Ciguatera phenomena. Although the immediate economic effects on the local community may be limited, it is crucial to educate the public about this phenomenon to increase public awareness, particularly in terms of preventing the occurrence of CFP.

Abstract

Background: Indonesia’s ageing population demands proactive strategies to preserve older adults’ quality of life, particularly in maintaining occupational independence, which often declines due to physical limitations, social isolation, and inadequate access to community-based rehabilitation. This community service aimed to enhance the understanding and participation of older adults in occupational independence through a culturally grounded, meaningful activity program in Kersan Brintikan Hamlet, Tirtomartani Village, Kalasan Subdistrict, Sleman Regency. Methods: A pre–post-test counselling design was employed with 52 participants (46 older adults and 6 elderly health cadres). The intervention included health screening, morning walking, anti-hypertension exercise, occupational therapy services, and interactive health education using visual media. A structured questionnaire comprising 10 closed-ended items was administered before and after the session to assess changes in knowledge. Results: Most participants were in the pre-elderly age group (64.3%), nearly gender-balanced (48.1% male, 51.9% female), and moderately to highly educated (78.7% senior high school or above). The mean understanding score significantly increased from 4.75 (pre-test) to 9.33 (post-test), while the standard deviation decreased from 1.064 to 0.857, indicating a homogeneous and substantial improvement in comprehension across participants. Conclusion: A participatory, contextually relevant program combining health promotion and meaningful occupational activities effectively enhances awareness of occupational independence among older adults. For sustainability, follow-up sessions, cadre capacity building, and inclusive outreach to older and male elders are recommended to support active ageing in the community.

Abstract

Background: High academic demands, intense device use, and irregular lifestyles among college students can impact their sleep quality. Poor sleep quality is suspected to be associated with increased diastolic blood pressure (DDP), which contributes to the risk of long-term hypertension. Objectives: This study aimed to examine the effect of sleep quality on diastolic blood pressure in college students. Methods: The study used a quantitative observational method with a cross-sectional design. The study was conducted at the Occupational Therapy Department of the Health Polytechnic of the Ministry of Health, Surakarta. The study population was first-year undergraduate students of the Applied Occupational Therapy Study Program, with a sample size of 91 people (total sampling). The study variables were measured using the Pittsburgh Sleep Quality Index (PSQI) and a digital sphygmomanometer. Data were analyzed using spearman rank and binary logistic regression using SPSS version 23. Results: The majority of study subjects had normal sleep quality (50,55%) and normal diastolic blood pressure (51,65%). The Spearman rank test results for sleep quality and TDD showed a correlation coefficient (r) of 0,475 with a p-value of 0,008. The binary logistic regression test obtained a coefficient value (B) of 1,128, Exp. (OR) of 3,088 with a p-value of 0,010. Conclusion: Sleep quality significantly affects the increased risk of TDD 3 times higher in students. Keywords: Sleep, Diastolic, Hypertension

Abstract

The main objective of this study was to determine the profile of endogenous intestinal bacteria of yellowfin tuna, Thunnus albacares that can function as potential probiotics in the digestive system and used for the maintenance of yellowfin tuna larvae. Wild yellowfin tuna, T. albacares was collected from the waters of Gerokgak, Buleleng, North Bali, Indonesia. Intestinal bacteria were isolated, identified, characterized, and followed by enzymatic hydrolysis activity tests, antagonistic tests and pathogenicity tests to select candidate bacteria as probiotics. The results of the enzymatic hydrolysis activity test showed that there were 4 isolates of candidate probiotic bacteria that were active in enzymatic synthesis for amylase, lipase, casease, lecithinase, gelatinase. Identification through Sanger sequencing resulted in 4 potential bacterial isolates as probiotics, namely Bacillus subtillis strain T-A1, Bacillus amyloliquefaciens strain T-N2, Bacillus subtillis strain T-O4, and Paraclostridium bifermentans strain T-O6. These four bacteria were not antagonistic between varieties and were not pathogenic in Tuna fish. Yellowfin tuna fed probiotic supplements grew faster (5.5002 ± 0.2 mm) than the control (4.9002 ± 0.4 mm). The success of yellowfin tuna seed production is expected to be sustainable and its implementation in the private sector for aquaculture purposes.

Abstract

The objective of this study is to seek the challenges experienced by English teachers in applying deep learning, focusing on their classroom experiences and perceptions using the activity theory as a  framework that focuses on its concepts of contradiction, boundary objects, and boundary crossing. This study used a semi-structure interview to understand the three participants' experiences as teachers in implementing Deep Learning in the classroom practices. Key challenges to their implementation came in the form: limited understanding, workload and time constraints, implementation barrier, limited administrative preparation, curriculum adaptation gap, and government requirement. However, the participants were able to overcome the challenges that arose by treating it as a connecting tool to connect their teaching methods. These findings raise important theoretical and practical issues related to strategies for overcoming challenges encountered in implementing deep learning, as implemented by the participants by institutional support and teachers training, implementation experience, facility support, and fellow teachers support. One of the connections is understanding how teachers manage the challenges they encounter by connecting their various activity systems as objects to overcome the obstacles that occur in the deep learning implementation system they use in the classroom.

Abstract

This research aimed to investigate students’ perceptions, difficulties and learning experiences in a blended listening class situation. In the present qualitative study, thirty (30) English Language Teaching (ELT) undergraduate students were selected using a purposeful sampling to be the research participants. Open-ended questionnaires were distributed for data collection. Then, the data collected were analyzed through reflexive thematic analysis, so as to interpret the findings and further understand students’ experiences. Results indicated that students appreciated the independence that was afforded online, such as being able to pause audio and access transcripts, but they enjoyed face-to-face sessions for the feedback they could obtain and the questions they could ask. Though faced with issues like technical problems and struggling to focus on learning, it is concluded that a blended approach can be both effective and efficient if the online and offline components are well-integrated and supported by an appropriate system, which makes it also highly applicable in EFL.
