Toxicity is the ability of a substance that is destructive when exposed to organisms. These substances can come from plants to used as plant-based pesticides. Siam orange peel waste (Citrus nobilis) can be used as the main ingredient of botanical pesticides because it contains bioactive compounds. The purpose of this research is to see the ability of the concentration of siam citrus fruit extracts that can cause mosquito death by 50%. This type of research is experimental and a quantitative approach. The experimental design used a Factorial Complete Randomized Design consisting of seven different treatments and three observation times. These treatments were the concentration of 0% conjoined orange peel extract as a negative control, 30%, 45%, 60%, 75%, 90%, and commercial products as a positive control, the treatment was carried out in four replications. Data were analyzed using probit regression analysis. Probit test results obtained that LC50 value is 49.86%, the concentration that can be used is in the treatment of P3 with a concentration of 60% of Siamese orange peel extract. The conclusion of this research proves that the administration of conjoined orange peel extract can cause Culex mosquito mortality by 50% at a concentration of 60%.

ABSTRACTThe Indian blue peacock (Pavo cristatus) is an introduced bird from India. The presence of this bird provides many economic benefits, one of which is the use of its beautiful feathers. One of the Exsitu conservation areas that conserves Indian blue peacocks is the Jantho City Sustainable White Desert Safari Park, located in Aceh, Indonesia. Considering that not much scientific information has been recorded about this bird, including its daily behavior, it is necessary to do research. Data collection was conducted in August-September 2020. This study aims to determine the daily behavior of male and female Indian blue peafowl (Pavo cristatus) in the Lestari White Desert Safari Park. The approach in this research is a qualitative descriptive approach. The data were obtained from the observation and documentation of the Indian blue peacock. The results showed that daily behaviors were found including self-care 383 times (27.51%), moving 471 times (33.84%), ingestive 357 times (25.65%), making sounds 20 times (1.44%). %), resting 142 times (10.20%) and social as much as 19 times (1.36%). The highest daily behavior frequency in male Indian blue peafowl was self-care behavior as much as 251 times (37.02%) and female Indian blue peacock on mobile behavior as much as 277 times (38.94%). The lowest frequency of daily behavior in male Indian blue peacocks, namely social behavior in fighting activities as much as 6 times (0.26%) and female Indian blue peacocks in vocal behavior, to be precise, emitted a sound when there was a threat, namely 2 times (0.08%) .Keywords: Indian blue peacock, Exsitu conservation, daily behavior.ABSTRAKBurung merak biru India (Pavo cristatus) merupakan burung introduksi dari India. Kehadiran burung ini memberikan banyak manfaat dari segi ekonomi salah satunya pemanfaatan pada bulunya yang indah. Salah satu kawasan konservasi Exsitu yang melestarikan burung merak biru India adalah Taman Safari Gurun Putih Lestari Kota Jantho yang terletak di Aceh, Indonesia. Mengingat belum banyak informasi ilmiah yang didata tentang burung ini termasuk perilaku harian, maka perlu dilakukan penelitian. Pengumpulan data dilakukan pada bulan Agustus-September 2020. Penelitian ini bertujuan untuk mengetahui perilaku harian burung merak biru India jantan dan betina (Pavo cristatus) di Taman Safari Gurun Putih Lestari. Pendekatan dalam penelitian ini adalah pendekatan deskriptif kualitatif. Data diperoleh dari observasi dan dokumentasi burung merak biru India.

ABSTRACT This study aims to determine the causal factors of obstacles lab work, and to find alternative solutions. This research was done on march until july 2020. The method in this study was carried out by means of a questionaire and literature review. Sample in this study were 11 SMA in Banda Aceh, with respondents 11 biology teachers teaching class XI and 99 students of class XI IPA. The data was analyzed using a percentage formula. The results of this research showed that the constraints for practical implementation included inadequate supporting facilities, lack of completeness of practicum materials, insufficient time allocation for practicum, lack of readiness of laboratory assistants in prepared practicum tools and materials, absence of laboratory assistants in several sample schools, and some biology teachers or laboratory assistants in sample schools have never attended training on practicum or the use of laboratory equipment. Solutions that can be given in overcoming the constraints of practicum implementation are applying for laboratory development funding assistance to related parties, planning time allocation properly, finding laboratory assistants by the school and holding training for teachers and laboratory assistants regarding laboratory techniques and laboratory management.Keywords: obtacles, lab practice, biologyABSTRAK Penelitian yang dilakukan di SMA Kota Banda Aceh bertujuan untuk mengetahui faktor penyebab kendala praktikum dan mencari solusi alternatif penyelesaiannya.
