Judul: Behavior of Komodo Dragon  in Rinca Island, Komodo National Park East Nusa Tenggara During the Covid-19 Pandemic
Abstrak: Pandemi Covid-19 mengakibatkan pemerintah menutup kegiatan wisata. Penelitian ini membandingkan perilaku komodo di kawasan di lokasi wisata Loh Buaya dan lokasi non wisata di Loh Baru SPTN I Pulau Rinca, setelah pembukaan kawasan yaitu 21 Juni hingga 28 September 2020. Pengamatan perilaku dilakukan terhadap 9 individu komodo (3 jantan dewasa, 3 betina dewasa, dan 3 remaja) pada masing-masing lokasi. Pengamatan perilaku menggunakan metode focal animal sampling dari jam 06.00 – 18.00 WITA dengan waktu pengamatan 30 jam per individu. Hasil penelitian menunjukkan terdapat perilaku agonistik, lokomosi, investigatif, ingestif, pemeliharaan dan agresif. Perilaku agresif kepada manusia, yang tidak ditemukan pada penelitian sebelumnya, terlihat pada 3 individu komodo dewasa. Penggunaan ruang oleh komodo menunjukkan bahwa komodo jantan lebih .banyak menggunakan ruang non alami pada kedua lokasi. Komodo betina lebih banyak menggunakan ruang alami pada lokasi non wisata dibandingkan pada lokasi wisata. Komodo remaja lebih banyak menggunakan ruang alami di kedua lokasi., Tourism activities in Komodo National Park have been halted due to goverment policies relating to the Covid-19 pandemic. This study compared the behavior of komodo dragons after opening at tourist’s site on Loh Buaya and non-tourist’s sites on Loh Baru SPTN I Rinca Island from June 21st- September 28th, 2020. Behavior observations were made on nine individual komodo dragons at each location, which include three adult males, three adult females, and three juveniles. Focal animal sampling approach was used for observation from 06.00 – 18.00 WITA, with a total observation duration of 30 hours for each individual. Komodo showed agonistic, locomotion, investigative, ingestive, maintenance, and aggresive behaviors. Aggresive behavior to human, which had not bee seen previously, was seen in three adult komodo dragons: two at tourism locations and one at non-tourism area. The use of space by komodo dragons shows that male use more non-natural space at both locations, female use more natural space at non-tourist locations than at tourism sites, while juvenile use more natural space in both locations.

Judul: Simulasi Perancangan Sel Surya Triple Junction Al0.3Ga0.7As / InP / Ge Menggunakan Program PC1D Dan Matlab
Abstrak: Solar cells are one source of renewable energy that harnesses sunlight for generating electricity. Increasing the efficiency of solar cells can be done by preparing a multiple layer of semiconductors with different energy gap, commonly referred to as multijunctions solar cells. Simulations were carried out in two different models. Model 1 is a simulation that generate different valuer of currents in each layer. while Model 2 is a simulation that generate the same value currents in each layer. In Model 1, those three layers of Al0.3Ga0.7As / InP / Ge produce 26.2 mA, 16.2 mA, and 11.0 mA of ISC current respectively. The total efficiency for this model is 38.86 %. As for simulation of Model 2 Isc current value is fixed for each layer is 11.9 mA. The total efficiency of Model 2 is obtained around 20.26 %. All simulations is performed using Solar Irradiance of 1367 W/m2 obtained from the calculation of the blackbody radiation spectrum, at 6000 K.
