Abstract

The problems of fish and plant cultivation are limited land, decreasing quality and quantity of water for human needs, food sources, and increasing population on earth. Optimization of fish farming with high stocking densities accompanied by high feeding will cause accumulation of organic matter in the culture containers which will worsen the quality of the rearing water which will ultimately have an impact on the physiological conditions, survival and growth of fish. One of the technologies for growing vegetables, fruit and fish farming that has been developed to overcome these obstacles is the Budikdamber system with red tilapia organisms and water spinach plants. The purpose of this study was to determine the quality of water with different stocking densities in the Budikdamber system with water spinach and without water spinach. The experimental design used a factorial complete randomized design with density treatment (A (2 fish/10L), B (4 fish/10L), C (6 fish/10L), D(8 fish/10L) and system (budikdamber with water spinach) (a) and without water spinach (b)). The results showed that temperature parameters ranged from 22.4 - 30.6°C, pH ranged from 6.4 - 8.9, and DO ranged from 1.07 - 16.4 mg/l. Parameters of temperature, pH, and DO are in a range that is not in accordance with optimum conditions (temperature = 25-32°C, pH = 6.5 – 8, and DO ≥3 ), but can still be tolerated by tilapia so that fish tilapia still survive. Water spinach plants can reduce ammonia so that the ammonia value in the treatment using kale decreased from week 1 to 4 and conversely, for budikdamber without water spinach, it increased from week 1 to week 4. The highest SR value was found in the Ba treatment (4 fish/10 liters) with water spinach is 91.67%.

Abstract

Reprocessing organic vegetable waste from conventional markets can have beneficial effects, such as producing bioenergy, reducing the need for inorganic fertilizers, and minimizing the volume of contaminants in the environment. Organic material composting can help lower greenhouse gas emissions and generate income. Physical-chemical factors like temperature, pH, particle size, moisture content, aeration, and CN ratio were used to regulate the breakdown process. Trichoderma harzianum, an effective microorganism, and Trichoderma harzianum helped the degradation process function. High-quality compost is produced by converting organic matter in a bioreactor system, where the solid substrate replenishes nutrients. Based on the optimum point of the decomposition procedure, the analytical findings were achieved. After that the material had been homogenized and aerated, this process took place (oxygen). When the temperature is increased, the active and ripening stages take place, which triggers the breakdown process. The ideal temperature for composting, between 30-45 °C, was reached. The temperature steadily drops when the majority of the material has broken down, and the composting process is complete.

Abstract

The Project Based Learning (PjBL) model has been widely applied in elementary schools. However, in practice, not a few teachers and students encounter obstacles when implementing the PjBL model. This research was conducted with the aim of identifying, compiling and describing studies regarding the obstacles in implementing the PjBL model in elementary schools and their solutions. This research is a library research. Researchers collected data from books and 40 articles related to the implementation of the PjBL model in elementary schools. Data analysis was performed using content analysis techniques. The results of the research show the fact that there are obstacles in implementing the PjBL model in elementary schools. These obstacles are: (1) poor time management; (2) teachers and students do not understand the essence of PjBL; (3) lack of motivation of teachers and students; (4) teachers and students have not been able to understand the relationship between PjBL and real life; (5) the inequality in the ability of students in groups makes the project implementation not run smoothly; (6) teachers are confused about adapting learning to the PjBL model, in other words the teacher is not able to understand when PjBL should be implemented; (7) lack of training for elementary school teachers on the PjBL model; and (8) inadequate facilities. At the end of the article, the researcher presents alternative solutions that can be further considered by teachers, schools and curriculum designers to overcome problems that occur during the implementation of PjBL in elementary schools

Abstract

In Era 4.0, the development of media and learning processes, such as using Instagram as a learning media, is required to make learning more meaningful. This is due to the fact that Instagram is a prominent social media network with over 400 million members. Learning models that can accommodate the skills required in the twenty-first century must be used to make learning more relevant. The discovery learning model is one of them. As a result, this study aims to evaluate the effect of using Instagram learning media on student learning outcomes using the discovery learning model on reaction rate material. A quasi-experimental design was used in this study, with an experimental class of 36 students and a control class of 36 students. This study employed ten multiple-choice questions in the pre-test and post-test to measure student learning outcomes. The N-Gain and Wilcoxon tests were then performed. The study findings demonstrate that employing Instagram learning media using the discovery learning model influences increasing student learning outcomes.
