Abstract

To overcome excess residues and fish mortality rates during transportation, natural ingredients, namely clove oil, can be used. Compounds in clove oil are considered safe because they use natural ingredients. The purpose of this study was to determine the effectiveness of using clove oil as an anesthetic agent with different doses on the length of time of unconsciousness and survival rate of tilapia. This research was conducted from May to June 2023. This research was carried out at the Bungus Fish Seed Center, Padang, and West Sumatera. The method used in this study is the experimental method. The design used in this study was a completely randomized design (CRD) consisting of 4 treatments and 3 replications. The treatment used in this study is use of clove oil with different doses. Treatment A1 = 0.5 ml L-1 water, A2 = 1 ml L-1 water, A3 = 1.5 ml L-1 water and A4 = 2 ml L-1 water. Observations of changes in tilapia behavior and water quality were analyzed descriptively, while the length of time of stupor and survival of tilapia obtained during the study were analyzed using analysis of variance (ANOVA). To see the differences between treatments, the Duncant Multiple Range Test (DMNRT) was performed. Data is processed using the SPSS 26 program. The conclusion that can be considered in this study is that the administration of clove oil with different doses as an anesthetic has a significant effect on the longest induction time, on the length of time the fish were unconscious, the length of time the fish regained consciousness and survival rate of tilapia. In treatment A2 with a dose of 1 mL L-1 of water, it was optimal to stun tilapia for 244 minutes with a survival of 88.89%.Keywords:Clove oilFish transportationTilapia

Abstract

This research was motivated by the decline in students' abilities and grades and the teaching and learning process carried out was still less effective because after several semesters the learning process was online. So to improve it, an efficient learning model is needed which is expected to improve students' learning abilities and values. This research aims to determine student learning outcomes using the Numbered Heads Together learning model based on Mind Mapping in class X IPA MAN 3 Langkat, to determine the effect of the Numbered Heads Together learning model based on Mind Mapping on student learning outcomes in class X IPA MAN 3 Langkat. This type of research is quantitative research and uses an experimental design, that is true experimetal design. The population in this study were all MAN 3 Langkat students.

Abstract

This study investigated the attitudes of eighth-grade students at SMP Negeri 13 Kota Bengkulu towards learning English as a foreign language. This study aimed to determine students' attitudes towards learning English as a foreign language, specifically whether they hold positive or negative views. A mixed method was used in this study to uncover students' attitudes, which focuses on combining quantitative and qualitative approaches. To gather data, a carefully and systematically designed questionnaire was adopted, consisting of 30 questions using a five-point Likert scale survey. 60 participants were asked to answer a questionnaire. Irn addirtiron, ther irnterrvirerw was applirerd to obtairn a morer irn-derpth analysirs and 15 students were selected to be interviewed to support the responses to the questionnaire given. Three aspects of attitude being explored are: behavioural, cognitive and emotional. Most students showed positive attitudes towards learning English as a foreign language. Based on the three aspects above, from a behavioural aspect, it is evident that most students exhibit good behaviour in learning English. From the cognitive aspect, students have confidence, awareness, and knowledge in learning English. And also from the emotional aspect, students show that almost all students have good emotional attitudes toward learning English. The results of data analysis show that students are motivated and have positive attitudes in the three aspects of attitude. In the sense that their attitudes seem to influence their understanding, their participation, and their interest in the perceived benefits of learning English, as well as their strategies to improve their abilities.

Abstract

This research aimed at improving the students’ mastery on tenses through the implementation a Project-Based Learning model using interviewing and reporting techniques. Class Action Research was the design of this research and was conducted on the first semester students of class A in the English Education Study Program at the University of Bengkulu, enrolled in the Basic English Grammar course. The research involved 37 participants and was carried out over two cycles, each consisted of three meetings. The stages of the research included planning, action, observation, and reflection. The instruments used were test and observation checklist. The result of the test showed an increase in the percentage of students who scored ≥70, from 54% in cycle 1 to 81% in cycle 2, indicating 27% improvement. The result of cycle 2 also demonstrated that the success indicator of this research has been achieved by more than 75% students got score ≥70. It can be concluded that the implementation of Project-Based Learning model using interviewing and reporting techniques effectively improve students’ mastery of tenses by encouraging them to apply grammatical knowledge in both speaking (interviewing) and writing (reporting), thereby deepening their understanding of grammar.

Abstract

Konseling keluarga berencana (KB) pada masa nifas merupakan salah satu langkah strategis untuk menurunkan angka kehamilan yang tidak direncanakan serta meningkatkan kesejahteraan ibu dan bayi. Dukungan dan sikap bidan sangat berpengaruh terhadap keberhasilan pemenuhan kebutuhan informasi dan pelayanan KB bagi ibu nifas. Penelitian ini bertujuan untuk mendeskripsikan dukungan dan sikap bidan dalam pemenuhan kebutuhan konseling KB pada ibu nifas di Puskesmas Lau Baleng Kabupaten Karo Tahun 2023. Metode yang digunakan adalah observasional deskriptif dengan pendekatan studi pengabdian masyarakat. Kegiatan meliputi wawancara, observasi, dan pemberian edukasi kepada ibu nifas terkait KB pasca persalinan. Hasil kegiatan menunjukkan bahwa sebagian besar ibu nifas (78%) mendapatkan dukungan penuh dari bidan dalam bentuk pemberian informasi, motivasi, dan bimbingan dalam memilih metode kontrasepsi. Sikap bidan yang ramah, terbuka, dan responsif mempermudah ibu dalam mengungkapkan kebutuhan dan kekhawatiran terkait KB. Kesimpulan penelitian ini adalah dukungan dan sikap bidan yang positif berkontribusi besar terhadap peningkatan pengetahuan dan minat ibu nifas untuk menggunakan KB pasca persalinan.

Abstract

Ectoparasites pose a significant threat to the health and productivity of vaname shrimp (Litopenaeus vannamei) in aquaculture settings, particularly in tropical regions. This study aimed to assess the prevalence, intensity, and dominance of ectoparasites in vaname shrimp ponds in Padang Pariaman, West Sumatra. This study was conducted from March to May 2024 in vaname shrimp ponds in Padang Pariaman, West Sumatra. Sampling was carried out at five different pond stations, and water quality assessments were carried out. Ectoparasites were identified, and their prevalence, intensity, and dominance were measured. Station II had the highest prevalence (100%), intensity (69 ind/shrimp), and dominance of ectoparasites from all other observation stations. The dominant types of ectoparasites were Epystylis sp. (37.81%), Zootamnium sp. (18.65%), and Vorticella sp. (20.64%). Water quality at five Vaname shrimp pond stations showed significant variations, especially in pH, COD, and ammonia parameters, with some values exceeding the quality standard. Station V was identified as the most critical location with the highest COD (90.08 mg/l) and ammonia (0.188 mg/l) values and pH below the optimal threshold. It is important to implement better pond management strategies to improve shrimp health and productivity while minimizing the ectoparasites on aquaculture systems in tropical regions.Keywords:Vaname shrimpEctoparasitesAquaculture managementWater quality
