Abstract

Betta splendens is an ornamental fish with a beauty appeal to the shape of the tail fin and color. The purpose of this study was to determine the effect of different temperatures and optimal temperatures on the growth rate and survival of betta fish fry (Betta splendens). The research method was experimental using a completely randomized design (CRD). With 4 treatments, namely P1 (control), P2 (25°C), P3 (27°C), P4 (29°C). The result of the highest specific weight growth rate was in treatment P4 (4.08 g), the lowest treatment was in treatment P2 (3.85 g). The highest specific length growth rate was in treatment P4 (1.78 cm), the lowest treatment was at P2 (1.52 cm). The highest feed conversion ratio (FCR) was in treatment P2 (5.82%), the lowest FCR value was in treatment P4 (6.23%). The survival rate of the highest Betta splendes fry was on average 100% in the P1, P3, and P4 treatments. The survival value of betta fish fry was lowest in treatment P2 (82%). The results of water quality parameters for P1 treatment temperature ranged from 27-28.2°C, pH ranged from 6.3-7.85, dissolved oxygen ranged from 6-8.8. The results of the analysis of variance test (Anova) on the growth of the specific weight of betta fry produced F-count -30.85 > F-table 5% (4.07). Specific length growth resulted in an F-count value of 2.75 < F-table 5% (4.07). Feed conversion ratio (FCR) F-count 1.24 < F-table 5% (4.07). The survival of betta fish fry resulted in F-count 12.60 > F-table 5% (4.07). The conclusion of the study is that temperature has a significant effect on the growth rate and survival of Betta splendens fry. The optimal temperature for growth rate was obtained in treatment P4 (29°C) of 4.08 g, optimal survival rate was obtained in treatments P1 (control), P3 (27°C), and P4 (29°C).

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

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.

Abstract

Banyaknya permasalahan hukum yang ditimbulkan akibat aktifitas ekonomi melalui transaksi elektronik, mengakibatkan perlunya Inovasi dan pembaharuan hukum dalam rangka mekanisme penyelesaian sengketa dalam jaringan yang sesuai dengan kompleksitas dan karakteristis unik dari transaksi elektronik. Adapun penelitian ini menggunakan pendekatan yuridis-normatif yang dikombinasikan dengan analisis deskriptif-kualitatif. Pendekatan yuridis-normatif digunakan untuk menelaah peraturan perundang-undangan yang berlaku dan relevan dengan penyelesaian sengketa transaksi elektronik melalui mekanisme Online Dispute Resolution (ODR). Hasil penelitian ini bahwa pengembangan penyelesaian sengketa online pada transaksi elektronik merupakan pengembangan dari mekanisme yang telah ada mengingat sifat lintas wilayah dan virtual dari transaksi yang dilakukan. Kemudian, berbagai negara telah mengembangkan model Online Disputes Resolution (ODR) yang sesuai dengan kebutuhan, infrastruktur hukum dan kesiapan teknologi masing-masing. Adapun Indonesia telah mencoba mengimplementasikannya walaupun belum terintegrasi dalam satu sistem nasional yang komprehensif. Bentuk paling nyata dari implementasi ODR dapat dilihat dari kebijakan internal platform e-commerce seperti Tokopedia, Shopee, Bukalapak, dan Lazada. Platform-platform ini telah menyediakan mekanisme penyelesaian sengketa antara penjual dan pembeli secara daring melalui fitur pelaporan masalah, negosiasi langsung, pengembalian dana, hingga intervensi tim mediasi internal. Temuan penelitian ini menegaskan pentingnya infrastruktur hukum dan teknologi dalam rangka memberikan kepastian hukum bagi para pihak yang menyelesaikan sengketanya melalui ODR

Abstract

Program pengabdian masyarakat ini dilaksanakan di SMK Darul Muttaqien, Lombok Timur, dengan fokus pada edukasi kesetaraan gender dan pencegahan pernikahan usia anak. Permasalahan utama meliputi tingginya angka putus sekolah akibat pernikahan dini, rendahnya kesadaran orang tua, serta keterbatasan kapasitas guru dalam melakukan pencegahan. Metode pelaksanaan mencakup baseline survey untuk memetakan kondisi awal, penyusunan modul edukasi, pelatihan guru, workshop siswa, post-test untuk mengukur perubahan pengetahuan, pembentukan peer educator, hingga kampanye sekolah dengan slogan “Remaja Sehat, Pesantren Kuat”. Hasil kegiatan menunjukkan peningkatan rata-rata lebih dari 30% pada pengetahuan guru terkait isu gender, hak remaja, dan strategi komunikasi pencegahan. Sementara itu, pengetahuan siswa meningkat rata-rata sebesar 33%, terutama pada aspek keterampilan mengambil keputusan untuk menunda pernikahan dan merancang masa depan pendidikan. Pembentukan santri pelopor menjadi strategi keberlanjutan agar edukasi sebaya terus berjalan di lingkungan pesantren. Secara teoretis, program ini memperkuat bukti bahwa intervensi pendidikan berbasis komunitas yang mengintegrasikan perspektif gender, nilai keagamaan, dan pendekatan vokasional efektif meningkatkan kesadaran kritis remaja dan pendidik. Secara praktis, model ini mudah direplikasi di pesantren lain karena memadukan pelatihan, pendampingan, dan peer learning dalam satu rangkaian intervensi. Program ini menunjukkan potensi signifikan dalam menekan praktik pernikahan usia anak di Indonesia melalui pendekatan pendidikan yang kontekstual dan berkelanjutan. Gender Equality Education and the Prevention of Child Marriage in Islamic Boarding Schools Abstract This community service program was conducted at SMK Darul Muttaqien, East Lombok, focusing on gender equality education and the prevention of child marriage. The main challenges identified included a high school dropout rate due to early marriage, low parental awareness, and limited teacher capacity in prevention efforts. The implementation method included a baseline survey to map the initial conditions, development of an education module, teacher training, a student workshop, a post-test to measure knowledge change, formation of peer educators, and a school campaign with the slogan “Healthy Youth, Strong Pesantren (Islamic Boarding School).” The results showed an average increase of more than 30% in teachers’ knowledge regarding gender issues, adolescent rights, and prevention communication strategies. Meanwhile, students' knowledge increased by an average of 33%, particularly in the aspect of decision-making skills to postpone marriage and plan their educational future. The formation of santri pelopor (pioneer students) serves as a sustainability strategy to ensure peer education continues within the pesantren environment. Theoretically, this program reinforces the evidence that community-based educational interventions which integrate gender perspectives, religious values, and a vocational approach are effective in increasing the critical awareness of adolescents and educators. Practically, this model is easily replicable in other pesantren because it combines training, mentoring, and peer learning in one intervention series. The program demonstrates significant potential in curbing the practice of child marriage in Indonesia through a contextual and sustainable educational approach.

Abstract

Sea urchins are a highly nutritious and economically valuable fishery product. In West Nusa Tenggara (NTB), particularly in Lombok, the public is still largely unaware of the benefits and market value of sea urchins in international markets such as Japan and Korea. Sea urchin gonads are consumed by Koreans and Japanese, and their high nutritional content is believed to improve health performance. However, there are obstacles in the sea urchin market development is the lack of proper standard operating procedures in post-harvest handling. Appropriate and standardized post-harvest techniques are not yet widely known or disseminated among sellers and sea urchin business actors. Prima Nusantara Cooperative is one of the cooperatives that supplies fishery products, including sea urchins, to exporting companies. Based on this, the current community service activity was conducted at Prima Nusantara Cooperative in East Lombok, targeting the cooperative staff. The aim is to provide both theoretical socialization and hands-on training to enhance the staff’s knowledge and skills in post-harvest handling of sea urchins. Through this technical guidance, it is expected that the quality of sea urchin products sold to exporters will improve and be more competitive in the Japanese and Korean markets. The method used during the technical training included presentation of materials on proper sea urchin handling procedures, followed by field practice involving sea urchin sampling, hands-on demonstrations, and direct mentoring through each stage of the process. The post-harvest handling stages included harvesting (collection), cleaning, shell breaking, rinsing, weighing, packaging, and storage at low temperatures.
