Abstract

The development of feed technology with the fortification of silkworm flour (Tubifex sp) is one solution that can be attempted. The silkworm contains high protein. This study aimed to analyze the effect of fish feed fortification with silkworm flour on the growth phase of Sangkuriang catfish. This research method used a Completely Randomized Design on one factor with three replications. The factors used were four treatments including A (95% fish flour + 5% silkworm flour), B (90% fish flour + 10% silkworm flour), C (85% fish flour + 15% silkworm flour), and D (80% fish flour + 20% silkworm flour). The results showed that the rate of length increase and weight increase of Sangkuriang catfish significantly increased when the catfish were in the 20-day enlargement phase in the tarpaulin pond. Treatment C (85% fish meal + 15% silkworm meal) was the best feed formulation seen in the high absolute weight growth (23,67 g), daily growth rate (2,66%), and feed utilization efficiency (1,32%). The results of this study can used as a reference in making artificial feed for the enlargement of Sangkuriang catfish.

Abstract

Fish meal is the main raw material used for feed because it contains high protein. Currently, the fulfillment of fish meal is still supplied from abroad. Indonesia imported 121 thousand tons of fish meal in 2023. This has an impact on the expensive price of feed. In addition, fish meal is produced from fishing in the sea which threatens the sustainability of the fish population. Maggot meal and mustard waste meal as local resources can be a solution in fulfilling alternative protein sources as sustainable fish feed ingredients. The study aimed to evaluate the growth response of tilapia to the effect of adding fish feed ingredients from maggot meal and mustard waste meal. The study used a single factor Completely Randomized Design with four treatments namely, P1: 75% fish meal + 12.5% ​​maggot meal + 12.5% ​​mustard waste meal, P2: 50% fish meal + 25% maggot meal + 25% mustard waste meal, P3: 25% fish meal + 37.5% maggot meal + 37.5% mustard waste meal, P4: 0% fish meal + 50% maggot meal + 50% mustard waste meal. The results showed that the provision of artificial feed based on maggots and mustard waste treatment P4 (0% fish meal + 50% maggot meal + 50% mustard waste meal) provided the best growth performance of tilapia with a daily growth rate of 2.13%, an absolute length of 2.61 cm, an absolute weight of 5.19 g, a percentage increase in length of 32.49% and 100% survival.

Abstract

Critical and creative thinking skills at SMA Pangudi Luhur (PL) Don Bosko are still classified as moderate critical thinking and less creative thinking, respectively. This illustrates that some students have not been able to interpret information scientifically and develop ideas to solve a problem. This study aims to analyze students' critical and creative thinking skills in understanding renewable energy material at SMA PL Don Bosko. These skills are important to face global challenges related to sustainable energy utilization. The research method used is descriptive with quantitative and qualitative approaches. Data were obtained through tests and questionnaires involving 20 students as respondents. The results of the analysis show that most students have critical thinking skills in the moderate category with an average achievement percentage of 62.94%, with the most dominant aspect of Elementary Clarification. However, students' creative thinking skills are still classified as lacking with an average achievement of 63.8%, with dominant results in the fluency aspect. Factors such as learning approaches, active student involvement, and learning resource support influence the development of these skills. This study suggests integrating a project-based learning model to improve students' critical and creative thinking skills on renewable energy materials.

Abstract

Allelopathy-based bioherbicides for drought-stressed sorghum plants are a concrete step towards sustainable agriculture. This study aimed to look at the characteristics of seed germination and flavonoid levels of extracts that have experienced various levels of drought stress. Extract materials were prepared from June to August 2024 at Bengkulu University Greenhouse, Kandang Limun, Bengkulu City, and bioassay tests were conducted in August 2024 at Pematang Gubernur, Muara Bangkahulu, Bengkulu City. Flavonoid analysis was performed at the Integrated Research and Testing Laboratory (LPPT) of Gadjah Mada University in August 2024. This research used a completely randomized design (CRD) with one factor. One sorghum variety, Super 2, was planted with water stress treatment through watering patterns every day, every 2 days, every 3 days, every 4 days, and every 5 days. The experimental unit was a petri dish, and the experiment was repeated four times. The Petri dish bioassay method was applied in this experiment. Each petri dish was given 10 mL of aqueous extract, and 25 mung bean seeds were planted and incubated for three days. The results showed that the highest flavonoid levels were achieved by watering every 5 days (3625.00 µg/g) and the lowest every day (3165.26 µg/g). Sprout inhibition occurred due to sorghum water extract treated with watering patterns.

Abstract

Misconceptions are a phenomenon that is often experienced in the learning process, that is important to identify so it doesn't occur continuously. However, in the research that has been conducted regarding misconceptions about the solar system, there has been no research conducted in elementary schools. In addition, the research that has been conducted is only based on interviews without diagnostic tests. This study aimed to identify the level of misconceptions about the solar system material of grade VI students at an elementary school in Trenggalek regency. This research was qualitative research using a three-tier Certainly Response Index. The first tier was conceptual understanding, the second tier was the reason for choosing an answer, the third tier was the student's level of confidence in the previous answer. The results of this study indicated that in general 56.875% of students experience misconceptions. If reviewed from each concept, 65.63% of students experienced misconceptions in solar system concepts, 51.65% of students experienced misconceptions in earth's rotation and revolution concepts, while 50% students experienced misconceptions in eclipse concepts. Meanwhile, if reviewed from each question, misconceptions occur in question number 10 about determining the characteristics of the sun with a percentage of 81.25% with a high misconception category. The results of this identification are expected to be used as a reference for designing learning materials on the solar system.
