This research aimed to determine the influence of usung ketapang leaf (Terminalia catappa) extract for treating common carp (Cyprinus carpio) seeds infected with Saprolegnia sp. fungus. The method employed in this study was an experiment. The test animals was used were common carp (Cyprinus carpio) seeds, totaling 225 individuals, divided into 5 treatments with 3 replications. In each treatment, 100 ppm ketapang leaf extract was administered was with different immersion duration, namely Treatment A (Control) B (3 hours of extract immersion), C (6 hours of extract immersion), D (9 hours of extract immersion), and E (12 hours of extract immersion). The treated common carp seeds were then raised in 15 aquariums with a volume 30 liters of water each, at a density of 1 individual per 2 liters, to observe healing time and survival rates. The research was conducted from August to September at the Tatelu Freshwater Aquaculture Research Institute. The research design used in this study was a Completely Randomized Design (CRD) using Analysis of Variance (ANOVA). Subsequently, post hoc tests were conducted using the Least Significant Difference (LSD) test. The results obtained indicated that the use of ketapang leaf (Terminalia catappa) extract signifucantly influences the treatment of common carp (Cyprinus carpio) seeds infected with Saprolegnia sp. Fungus. The best healing time is in Treatment E (6 days), D (7 days), C (9 days), B (10 days), and A (not healed). The highest survival rates are in Treatment E (57.78%), D (46.67%), C (31.11%), B (26.67%), and A (8.89%).

Abstract

Cherax quadricarinatus is a high-value freshwater crustacean, yet live transportation remains a major challenge as it may reduce survival and induce physiological stress. This study aimed to evaluate the use of rice straw, coconut husk, and banana stem as organic packing media on induction time, sedation time, survival, and molting percentage of C. quadricarinatus juveniles. A completely randomized design was applied with three treatments (JP, SK, BP), each in triplicate, using a total of 90 juveniles (4–6 cm). Data were analyzed using ANOVA followed by the LSD test at a 95% confidence level. Results indicated that transport media influenced lobster physiological responses. Coconut husk resulted in relatively longer induction and sedation times, whereas banana stem yielded the highest survival rate and molting percentage. Although statistical differences were not significant, data trends confirmed the superiority of banana stem in maintaining moisture and physiological stability during transportation. This study recommends banana stem as an eco-friendly and effective organic medium for live transport of C. quadricarinatus juveniles. Keywords: Cherax quadricarinatus; dry transport; organic medium; survival Abstrak.  Cherax quadricarinatus merupakan spesies krustasea air tawar bernilai ekonomi tinggi, namun transportasi hidup masih menjadi kendala utama karena dapat menurunkan kelangsungan hidup serta memicu stres fisiologis. Penelitian ini bertujuan mengevaluasi pemanfaatan jerami padi, sabut kelapa, serta batang pisang sebagai media organik transportasi terhadap waktu induksi, waktu sedatif, survival, serta persentase molting benih C. quadricarinatus. Rancangan acak lengkap digunakan dengan tiga perlakuan media (JP, SK, BP) masing-masing tiga ulangan, menggunakan total 90 ekor benih berukuran 4–6 cm. Data dianalisis menggunakan ANOVA serta uji BNT pada taraf kepercayaan 95%. Hasil penelitian menunjukkan bahwa media berpengaruh terhadap kondisi fisiologis lobster. Sabut kelapa menghasilkan waktu induksi dan sedatif relatif lebih lama, sedangkan batang pisang menunjukkan survival tertinggi serta persentase molting lebih besar dibandingkan dengan perlakuan lain. Meskipun perbedaan statistik tidak signifikan, tren data menegaskan bahwa batang pisang lebih efektif mempertahankan kelembapan serta stabilitas fisiologis selama transportasi. Penelitian ini merekomendasikan batang pisang sebagai media transportasi organik ramah lingkungan untuk mendukung distribusi benih C. quadricarinatus. Kata kunci: Cherax quadricarinatus; transportasi kering; media organik; survival

Abstract

The cultivation of tubifex worms (Tubifex sp) traditionally utilizes nearly 100% organic materials as the growing medium; however, this approach has not yielded optimal biomass compared to the use of fermented organic materials. This study aims to evaluate the effectiveness of fermented media in enhancing the population density and biomass of tubifex worms. The study employed a Completely Randomized Design (CRD) with three treatments and four replications. The treatments consisted of different combinations of fermented organic materials, specifically cow manure and tofu waste, with varying proportions in each treatment. Measurements of population density and biomass were conducted after a specified rearing period. The cultivation was carried out in locations proximate to water sources to ensure optimal environmental conditions. The findings indicated that the use of combined fermented organic materials significantly affected the population density and biomass of tubifex worms (Tubifex sp). Treatment A demonstrated the highest population density and biomass, reaching 44.675 grams. These results suggest that fermented media provide a more conducive environment for the growth and reproduction of tubifex worms compared to non-fermented media. The application of fermented media composed of cow manure and tofu waste effectively enhances the population density and biomass of tubifex worms (Tubifex sp). Additionally, conducting cultivation near reliable water sources is crucial for supporting optimal worm growth. Future cultivation practices are recommended to incorporate fermented media and ensure adequate water availability to achieve maximum yield.

Abstract

The demand for ornamental fish is increasing every year, one of the most popular ornamental fish is comet fish. Feed is a very important factor in supporting the quality of comet fish produced. In terms of improving the color quality of comet fish, the feed given must contain karatonoid as a color-forming content of comet fish. Moringa leaves are one of the ingredients that contain karatoneids and are an alternative pigmentation factor for ornamental fish. Feeding dosage is also a factor that needs to be considered in the maintenance of comet fish. Feed raw materials that have been formulated are first weighed one by one to match the feed formulation that has been determined. This study was conducted for 42 days by measuring the growth and brightness of fish color once a week. Feeding was carried out 3 times a day, namely in the morning, afternoon, and evening with a dose of feeding in each treatment of 10%, 15%, 20%, and 25%. This study used a complete randomized design. The results showed that the average change in fish body length during the observation of each treatment experienced an increase during maintenance, where the highest treatment was in treatment D by 1.69 cm. Observation of absolute weight is a parameter observed to determine the effect of feed containing moringa flour on comet fish. The highest average absolute weight growth rate at the end of the study was in treatment D amounting to 2.63 gr.

Abstract

Lemon cichlid fish has the Latin name (Neolamprologus leleupi) is one of the ornamental fish species with a promising level of potential. The brightness of the color of lemon cichlid fish (Neolamprologus leleupi) is one of the important factors that must be considered by lemon cichlid fish farmers. This is because the brighter the color of the lemon cichlid fish, the higher the selling price, thus affecting the income of lemon cichlid fish farmers. Efforts to increase the brightness of the color of the fish can be done by adding carotenoids derived from marigold flowers (Tagetes erecta) which are mixed into the feed. The use of marigold flower flour (Tagetes erecta) in feed to improve the color of lemon cichlid fish has not been widely carried out, so this study was conducted. This study aims to determine the addition of marigold flower flour to fish feed can provide a real effect. The method used in this study is an experimental method with a completely randomized design (CRD). The main treatment carried out was the provision of marigold flower flour with different doses, namely: 1%, 2%, 3% and one control treatment (without the provision of marigold flower flour). The addition of Marigold flower flour did not give any significant effect based on the results obtained.

Abstract

Learning interest plays a crucial role in promoting students' engagement and persistence in learning English as a Foreign Language (EFL). However, limited studies have explored how students' English learning interest develops within the context of pesantren-based junior secondary schools. This study aimed to explore students' English learning interest at MTs. Raden Rahmat and to identify the factors influencing through the Four-Phase Model of Interest Development. A qualitative case study design was employed involving forty eighth-grade students, with six students purposively selected for semi-structured interviews. One English teacher also participated as a key informant to provide complementary perspectives. Data were collected through questionnaires, classroom observations, and semi-structured interviews and analysed using thematic analysis, while descriptive statistics were used to summarise the questionnaire results. Data triangulation was employed to enhance the trustworthiness of the findings. The findings revealed that 60% of the students demonstrated triggered situational interest, 25% maintained situational interest, and 15% exhibited emerging individual interest, whereas none reached the well-developed individual interest phase. Findings from the interviews further indicated that students perceived English as a difficult subject, low intrinsic motivation, and limited independent learning opportunities were the major factors hindering the development of their learning interest. Overall, the findings suggest that students' English learning interest remains predominantly at the situational level, influenced by meaningful classroom experiences and their perceptions of the relevance and value of English. Therefore, English teachers should implement interactive, contextual, and student-centred instructional practices to foster more sustainable individual interest in learning English.

Abstract

Aktivitas antropogenik di sekitar Danau Limboto telah memicu penurunan kualitas perairan dan status danau kritis. Penelitian ini bertujuan untuk mengidentifikasi struktur komunitas plankton sebagai bioindikator kondisi ekologis terkini Danau Limboto. Pengambilan sampel air dilakukan secara purposive sampling menggunakan metode penyaringan horizontal dengan plankton net pada satu stasiun pengamatan (koordinat 0.597094 LU dan 123.005491 BT). Identifikasi kuantitatif menerapkan teknik pencacahan zigzag di dalam bilik hitung Sedgwick-Rafter Counting Chamber (SRC) di bawah mikroskop digital perbesaran 100×. Hasil pemindaian pada 120 kotak grid, yang teridentifikasi jelas menunjukkan keberadaan 43 taksa (genus) fitoplankton dari 3 kelas dengan total kelimpahan 111 individu. Kelas Bacillariophyceae (diatom) menampung kekayaan taksa tertinggi yaitu sebanyak 16 genus yang didominasi oleh Aulacoseira, mencerminkan karakteristik hidrologi danau yang dinamis, dangkal, dan bersirkulasi aktif. Sebaliknya, secara kuantitas jumlah individu terbesar dikoleksi oleh kelas Cyanophyceae (alga biru-hijau) yang mencapai 38% dari total sampel (42 individu). Dominansi genus alga biru-hijau seperti Oscillatoria dan Lyngbya menjadi indikator biologis kuat terjadinya pengayaan unsur hara (eutrofikasi) akut akibat limbah domestik dan pertanian. Kesimpulan penelitian menunjukkan struktur komunitas fitoplankton Danau Limboto saat ini berada dalam status kritis terganggu dengan risiko tinggi terjadinya fenomena Harmful Algal Blooms (HABs). Penelitian lanjutan disarankan untuk mengukur volume air secara presisi guna menentukan nilai kelimpahan mutlak dan indeks keanekaragaman.

Abstract

Ikan Tongkol (Euthynnus affinis) merupakan jenis pelagis kecil yang banyak ditangkap oleh nelayan lokal Kabupaten Boalemo dan memiliki nilai ekonomis penting. Namun, peningkatan aktivitas penangkapan yang tidak diimbangi dengan pengelolaan berbasis data stok ikan berisiko menyebabkan overfishing dan penurunan populasi sumber daya tersebut. Oleh karena itu, diperlukan upaya untuk menjaga keberlanjutan pemanfaatan sumber daya ikan, salah satunya melalui pendekatan Maximum Sustainable Yield (MSY) atau Hasil Tangkapan Maksimum yang Berkelanjutan. Penelitian ini bertujuan untuk menganalisis data hasil tangkapan dan upaya penangkapan ikan tongkol dan mengestimasi nilai MSY menggunakan metode surplus produksi. Hasil penelitian menunjukkan bahwa hasil tangkapan ikan tongkol telah melebihi MSY pada tahun 2022. Penelitian menyoroti bahwa berbagai jenis pengelolaan berbasis area dapat efektif dalam mencapai hasil konservasi positif, namun banyak di antara daerah yang dikelola tidak memenuhi kriteria efektivitas.
