Due to the pandemic of Covid-19, all universities and institutions in Malaysia are closed during the pandemic to avoid the spread of Covid-19. The face-to-face learning and teaching session are replaced by online learning and teaching session. Online learning was being implemented to deliver a seamless teaching and learning process so that the academic session can continue with the new norm through MCO and social distancing. There are barriers to conducting the practical class or hands-on practice for aquaponic topics due to the teaching and learning online classes. Therefore, this condition may affect the knowledge and understanding or performance of the student on aquaponic topics that require hands-on teaching and learning. Moreover, students at home who do not have the necessary equipment and tools for the practical session are among the challenges of doing practical sessions. Some materials, such as Rockwool and net pot, must be purchased as a set, but students may only require a portion of them, making the purchase burdensome to complete on their own aquaponic. To overcome the problem, the teaching aids "Aquaponic Mini Models was developed. The purpose of this study was to identify the expert perspective on the development and usability of teaching aids "Aquaponic Mini Models" for aquaculture course. The teaching aids “Aquaponic Mini Models” was created using the ADDIE model through five phases: analysis, design, development, implementation, and evaluation. The research method used in this study is a quantitative method (questionnaire survey). In this study, a set of questionnaires was used to elicit data from the experts. Nine experts from the Faculty Technical and Vocational were chosen for their experience developing learning aid kits and teaching pedagogy. All data obtained were analyzed using computer software Statistical Package for Social Science SPSS version 24' to obtain the frequency, percentage, and mean through descriptive analysis. The result showed that the expert perception on the essential elements of teaching aid, necessary features for teaching aid, the development of the Aquaponic Mini Model Learning Aid Kit (Design and Layout) and the usability of the Aquaponic Mini Model Learning Aid Kit has the overall mean perception of 2.00, implying perceptions were good. Therefore, Overall, the result showed that the Aquaponic Mini Models Learning Aid Kit could be developed and used as a learning aid kit for aquaculture courses to increase student understanding and skills in teaching and learning. Moreover, using the Aquaponic Mini Model Learning Aid Kit, students will develop and build the learning kit independently and the results will be more precise and more understandable. For a teacher, the use of teaching aid can save time in determining efficient teaching and learning processes.
Chemical fertilizer application is one of the most common procedures in today's developing intensive agriculture. However, long-term use of chemical fertilizers has resulted in many unintended consequences such as environmental pollution including contribution of toxicity to the soil. Excessive toxicity of soil may prevent the growing of plants roots and containing low nutrients in plants. Previous study has proven that organic fertilizers may increase the plants growth and its soil quality. Therefore, this study was conducted to determine the effects of chicken manure and shrimp paste application on chili pepper growth. This study used Randomized Complete Block Design (RCBD) as an experimental design. There were 4 treatments with 5 replications in this study. The treatments were supplied with: T1 (tap water); T2 (30 gram of chicken manure); T3 (30 mL of shrimp paste solution); T4 (15 gram of chicken manure and 15 mL of shrimp paste). The parameters that have been observed in this study were root length, shoot length, leaves number and soil pH. The data was analysed by using Analysis of Variance (ANOVA), Statistical Package for the Social Sciences (SPSS) and the differences between treatments mean were compared using Tukey test with significant level (P≤0.05). The results of this experiment showed that the chicken manure and shrimp paste solution had significant effects for all parameters measured except for soil pH value. All treatments were significantly higher compared to control. This study was conducted to provide more information as well as awareness to the agricultural industry and society to mainly use organic fertilizers in any cultivation of food product.
Litopenaeus Vannamei is a high-value commodity shrimp species in the aquaculture sector, especially Asia. Unfortunately, disease attack is a problem that emerges from shrimp aquaculture to gain high profit. Among the common disease that usually infects L. Vannamei are white spot disease (WSD) and Fusarium bacteria which causes black gill disease. This problem arises from farmers' lack of knowledge about shrimp disease, low management attitude and poor aquaculture management practices. Therefore, this research objective is to investigate a farmer's level of knowledge, attitude, and practices on the Litopenaeus Vannamei shrimp disease. The research method used in this study is a quantitative method (questionnaire survey) using a google form and the questionnaire was distributed online. The respondents were chosen from the L. Vannamei farmers (50 respondents) in Kota Bharu, Kelantan. The survey was open for one month between 15th November and 15th December 2021. The data was analysed using IBM SPPS software version 24.0 to obtain the frequency, percentage and descriptive analysis to analyse the level of knowledge, attitude and practices of L. Vannamei farmers on the shrimp disease in pond culture. This study showed that the level of knowledge, attitude, and practices of L. Vannamei farmers on the shrimp disease in pond culture is high, as can be seen by the good attitude in L. Vannamei management and having good aquaculture management practices. In conclusion, the high level of knowledge, attitude and practices of L. Vannamei farmers helps to motivate farmers to apply good management on shrimp cultivation to prevent the disease and increase the production of high-quality seeds.
Due to the COVID-19, teachers forced to perform online teaching and learning procedures, which made it impossible for teachers to track students of understanding, especially in practical classes. Teaching and learning in an online class, limiting the learning process of practical classes or hands-on experience for aquaculture, specifically in canvas system topics. In aquaculture subject, practical classes are an essential thing. Students do the fieldwork and at the same time, individual skills tested to measures the level of understanding in specific topics. In this regard, the development of teaching aids kit Mini Model (Canvas system) is required to help teachers enhance students’ understanding and skills related to aquaculture subjects. The development of teaching aid is a critical phase to make sure the teaching aids develop in accordance with the objectives and work well. Therefore, it is important to have an expert perception of the development and usability of the teaching aid kit Canvas system mini model. In this study, nine experts were chosen from the Faculty Technical and Vocational, Sultan Idris Education University based on their experience developing teaching aid kits and pedagogy. A set of questionnaires was distributed to the experts to obtain the required information and data. All data obtained were analysed using Statistical Package for Social Science SPSS version 24' to obtain the frequency, percentage and mean through descriptive analysis. The study’s findings show that the development and usability of the teaching Aids Kit Mini Model (Canvas system) is acceptable and can be used as a teaching aid for aquaculture subject.
Sustainability of the aquaculture industry can be secure through the induce breeding technique. One way that induce breeding can do is to increase the rate of maturation and ovulation in making sure the availability of good quality fish seed all year round. Here, we investigate how Ovaprim hormone impact the reproduction of Clarias gariepinusincluding spawning rate, fecundity, hatching and survival rate. For this purpose, Six broodstocks were divided in three experimental treatments and injected intramuscularly with different doses of Ovaprim hormone of T1: 0.25ml/kg for female and 0.125ml/kg for male, T2: 0.5ml/kg for female and 0.25ml/kg for male and T3: 1.0ml/kg for female and 0.5ml/kg for male. According to our results, broodstock injected with Ovaprim hormone of dose of T3: 1.0ml/kg for female and 0.5ml/kg for male showed higher eggs production and hatching rate compared to other treatment. The results of this study suggest that a dosage of 1.0ml/kg Ovaprim for female and 0.5ml/kg for male have a better effect on the reproductive parameter of Clarias gariepinus.
