Abstract

Catfish is a freshwater commodity often found in traditional and modern markets. Cultivation is also carried out in almost all regions, but the obstacle is feed availability. Therefore, we are looking for feed ingredients that are widely available and capable of increasing catfish growth quickly. Octopus is a fishery commodity abundant in certain seasons and requires processing so that it is not wasted. Octopus can be made into meal and used as raw material for catfish feed. The research aimed to analyze the effect of adding octopus meal to commercial feed for the growth of catfish (Clarias sp.). This research used an experimental method with 4 treatments (P1: 100% pellets, 0% octopus (without addition), P2: 98% pellets, 2% octopus meal, P3: 96% pellets, 4% octopus meal, P4: 94% pellets, 6% octopus meal) and 3 repetitions. The results showed that the addition of octopus meal increased the growth of catfish with the best treatment, namely the P4 treatment. Adding octopus meal to commercial feed gave significant results on absolute weight growth, specific weight growth, absolute length growth, specific length growth, feed conversion ratio, and feed efficiency level but did not affect the survival rate of catfish.

Abstract

Catfish is a freshwater consumption fish that is most widely cultivated in Indonesia, occupying the top position in total production, catfish has contributed more than 10% of the national aquaculture production with a growth rate of 17 to 18%. Catfish has a fairly high protein content and is very competent to improve human nutrition, because it is classified as a high quality food and its uniqueness is a must. Due to the high density of cultivation, a technology is needed that supports the maintenance of oxygen content, namely microbubble. This research was conducted for 50 days by observing the growth of catfish in 3 different conditions, namely without aerator, with conventional aerator and microbubble. The results showed that the absolute weight and absolute length without aeration were 5.2 g and 3.5 cm. then with a conventional aerator it produces 5.3 g and 3.5 cm. and on Microbubble it is 9.2 g and 7.2 cm. Judging from some of the parameter test results, it shows that raising catfish using microbubble increases the growth rate and productivity of catfish.

Abstract

Platy fish is freshwater ornamental fish which has beautiful color so it has high aesthetic and economic value, belonging to a type of fish called the “live bearer” or having the ability to give birth. Current problem faced by platy fish farmers are the low production to meet the rising market demand. This causes the lack of ability to reach the desired production target. This research evaluate the effect of giving Oodev through feed to the amount of production of larvae platy fish Xhiphophorus sp. with different dose. The research used completely randomized design with treatment of different Oodev dose which were P1 (0 ml/kg fish), P2 (0,5 ml/kg fish) P3 (1,0 ml/kg fish) and P4 (1,5 Mml/kg fish) each repeated three times. Oodev hormone was given through feed two times a day with feeding rate (FR) 3%. Results showed that the giving of OODEV could raise the number of larvaes produced by female parent with the highest number of 29,33 larvaes on the P3 and lowest treatment as much as 15 larvaes at P1 (P<0,05). The number of larvae produced by the female parent P3 treatment provides the best results with total larvae amount of 176 or average each treatment of 58,76 larvaes.

Abstract

Mud crab (Scylla serrata) is a fishery commodity that has high economic value and has a wide salinity tolerance so that its growth can be developed. The growth of mud crabs can be influenced by genetic traits such as moulting. In cultivation activities there are methods that can accelerate the moulting process such as environmental engineering (increasing and decreasing the salinity of the maintenance media) and mutilation. This study aims to determine the growth and fastest moulting time of crabs in media with different salinities in controlled media. The method used is an experimental method with a Completely Randomized Design (CRD) consisting of 5 treatments and 3 replications, namely: (Control), (P1: 5 ppt), (P2: 10 ppt), (P3: 15 ppt) and (P4: 20 ppt) which are given to mud crabs for 45 days. The results showed that at 5 ppt salinity obtained the fastest moulting time which was 24.3 days and the longest was at 20 ppt salinity for 39 days, while the highest growth was obtained in the 15 ppt salinity treatment with an average absolute weight of 27.3 grams and the lowest was in the control treatment with an average absolute weight of 18.3 grams.

Abstract

Cyberspace digambarkan sebagai Konsep yang sangat dibutuhkan masyarakat modern hingga bergantung pada teknologi untuk menjalankan aktivitas sehari-hari dan menjadi wadah untuk mengatasi konflik politik, membuka pasar, dan menjembatani kesenjangan sosial. Oleh karena itu, regulasi cyberspace menjadi krusial untuk memastikan keamanan, privasi, dan inklusivitas dalam ruang digital. Transformasi siber yang berlangsung sangat cepat telah membawa berbagai permasalahan baru dalam dunia hukum. Kajian artikel ini menggunakan pendekatan normatif, konseptual, dan komparatif dengan meninjau peraturan perundang-undangan. Artikel ini mengkaji tentang kesenjangan antara transformasi siber dan regulasi hukum yang ada di Indonesia; tantangan utama yang dihadapi oleh lembaga hukum dalam menghadapi kompleksitas dunia siber, termasuk isu yurisdiksi dan harmonisasi hukum internasional; dan rekomendasi strategis yang dapat diberikan untuk menciptakan regulasi yang lebih adaptif terhadap teknologi digital di Indonesia. Sehingga berhasil mengidentifikasi beberapa kesenjangan utama dalam regulasi hukum yang ada di Indonesia terkait dengan transformasi digital, diantaranya pertama, regulasi yang ada seperti UU ITE dan UU Hak Cipta belum sepenuhnya mampu mengakomodasi isu-isu terkini dalam teknologi digital, kedua, ada ketidaksesuaian antara hukum yang berlaku dan kenyataan di dunia digital, yang sering kali menimbulkan ketidakseimbangan dalam penegakan hukum. Tantangan yang dihadapi tentunya implementasi hukum di dunia maya masih terbentur oleh hambatan yurisdiksi dan kurangnya kerjasama internasional yang efektif, serta ketidakcukupan kompetensi aparat penegak hukum dalam menangani kejahatan dunia maya. Tantangan lain adalah ketidakpastian hukum dalam penyelesaian kasus kejahatan siber. Selain itu, harmonisasi hukum internasional masih menghadapi kendala akibat perbedaan sistem hukum dan kebijakan antarnegara.

Abstract

Color enhancement in ornamental fish is an essential quality parameter that directly influences market value and consumer preference. Natural pigments derived from marine resources, such as seaweed, offer a sustainable alternative to synthetic color enhancers. This study aimed to determine the effect of seaweed meal (Eucheuma cottonii) on the color brightness of goldfish (Carassius auratus). Goldfish used had an initial weight of 10.12 ± 0.06 g and an initial length of 5.08 ± 0.02 cm. Fish were fed using the ad libitum method three times daily with four feed treatments: P1 (Control), P2 (4 g seaweed meal), P3 (8 g seaweed meal), and P4 (12 g seaweed meal). The study was conducted for 45 days to evaluate growth performance and color characteristics. A completely randomized design with four treatments and three replications was applied. Data were analyzed using one-way ANOVA at a 95% confidence level (p < 0.05). Results showed that the addition of seaweed meal significantly influenced the red hue variable in goldfish. Brightness showed no significant difference among treatments, with the highest value in P4 (55.88%) and the lowest in P3 (52.68%). The red hue differed significantly, with the highest value in P3 (16.96%) and the lowest in P1 (9.13%). The yellow hue showed no significant difference, with values ranging from 36.68% (P1) to 38.43% (P2). Overall, supplementation with 8 g of seaweed meal effectively enhanced the visual red hue of goldfish.

Abstract

This study aims to analyze the impact of the implementation of PhET simulation-assisted deep learning on students' problem-solving skills by considering their level of learning motivation. The research method used a quasi-experimental design with a 2x2 factorial model. The research subjects involved two classes: an experimental class that received PhET simulation-assisted deep learning treatment and a control class that received conventional learning. The research instruments included a problem-solving skills test in the form of essay questions and a validated learning motivation questionnaire. Data analysis was conducted using a two-way ANOVA test to examine the effect of learning methods, motivation levels, and their interaction on problem-solving skills. The results showed that PhET simulation-assisted deep learning significantly improved problem-solving skills compared to conventional learning. Students with high learning motivation achieved better problem-solving scores than students with low motivation, both in the experimental and control groups. In addition, there was a significant interaction between learning methods and learning motivation, where students with high motivation who participated in deep learning showed the highest improvement in problem-solving skills. These findings confirm that PhET simulation-assisted deep learning is effective for developing critical thinking and problem-solving skills, especially in students with high learning motivation. The implications of this research encourage educators to integrate in-depth learning and technology-based interactive media in the science learning process, as well as pay attention to strategies for increasing learning motivation as an important factor in achieving optimal learning outcomes.
