Abstract

Bandung CO2 emissions continue to increase in line with its population. The emissions source comes from the industrial, transportation, Liquefied Petroleum Gas (LPG), household, and livestock sectors, whereas CO2 absorption only comes from vegetation through photosynthesis. High CO2 emissions could decrease air quality and reduce environmental health. This study aims to estimate the amount of CO2 emissions and their absorption in Bandung by implementing CO2 Emission Rate Reduction Simulation (CERRS). The simulation comprises four scenarios, namely substitution of vehicle fuel and the application of smart driving techniques, optimization of waste processing in IWPS, processing 90% of livestock waste into biogas, and green space development of 30% of Bandung City area. Estimated CO2 emission and absorption rates were calculated for the next 10 years (2021-2030) using the Stella program version 9.0.2. The results showed that without implementing the CERRS, the amount of CO2 emissions in Bandung in 2030 was estimated to reach 10,983,666.82 tons while implementing the CERRS was 2,361,721.30 tons. Without implementing the CERRS, the estimated amount of CO2 absorptions in 2030 was 214,235.11 tons, while implementing the CERRS was 2,785,703.11 tons. It is expected that the application of the CERRS could reduce the level of CO2 emissions in Bandung by 78.5% and increase CO2 absorptions by 1,200.3%.

Abstract

Fish as natural predators of mosquito larvae is a way of controlling mosquito larvae biologically that does not pose a risk to the health of organisms and environmental damage and overcoming the problem of mosquito resistance to chemical larvacide. One fish tested in the study was the rosy barb (Pethia conchonius) and lemon cichlid (Labidochromis caeruleus). Objectives: To analyzed  a difference in the predation ability of male and female fish to the larvae. Methods: This was an experimental study in the laboratory with a post-test-only design and five replications. One aquarium contains one liter of water, one fish, and 25 larvae of Ae. aegypti. Fish testing starts in the afternoon at 15.00 WIB. Observation the predation time of the fish until the fish eat all the larvae. Results: The average predation time of male P. conchonius fish was 1.57 minutes, and the female was 76.05 minutes. The average predation time of male L. caeruleus fish was 36.72 minutes and for females, 22.08 minutes. There was a significant difference between the predation of the male and female P. conchonius fish groups. There was no significant difference between the predation of male and female L. caeruleus fish groups to Ae. aegypti larvae. Conclusion: Rosy barb (P. conchonius) and lemon cichlid (L. caeruleus) have the potential to control the larval population of the Ae. aegypti mosquito. Rosy barb male has faster predation ability than other fish.Keywords:  Aedes aegypti, female, Labidochromis caeruleus, Pethia conchonius, male

Abstract

One important factor in improving the quality of learning is the classroom atmosphere, which is formed through the activities carried out in it between the teacher and students with position, posture, and body language, as non-verbal communication, and the use of words, intonation, and pronunciation as verbal communication. Another important factor is the characteristics of the space where the activity takes place (setting). In applying the student-centered approach, which motivates students to learn more actively and not depend on the teacher, the role of a teacher is very important to always be able to improvise, exploit the potential and position, for the success of the teaching-learning process in schools. The purpose of activities in the field of interior science architecture community service at SMAK St. This framework is to strengthen the participation of teachers and students through the setting of learning spaces that support the establishment of communication as desired. The method used is observation of the physical environment and surveys of teachers and students about the communication experience and the convenience of learning on three subjects that are considered difficult, namely Chemistry, Biology, and English. The survey results show that effective verbal and non-verbal communication media between teachers and students and fellow students is triggered by the setting of the space outside the classroom, with more relaxed and enjoyable reasons, such as in a library room. This has a real impact on increasing student motivation in the form of subjects' likes and grades. Other results indicate an increase in teacher awareness that changes in varied learning space settings can support non-verbal communication with students. How to cite:Anggraeni, Lya Dewi. (2020).
