Judul: Observation of Daily Behavior of Javan slow loris (Nycticebus javanicus) Using Camera Trap at Yayasan Inisiasi Alam Rehabilitasi Indonesia.
Abstrak: Kukang jawa (Nycticebus javanicus) merupakan primata endemik Indonesia yang masuk dalam kategori kritis (critically endangered) oleh IUCN. Penelitian ini bertujuan untuk mengidentifikasi perilaku harian individu kukang jawa kandidat release dan individu yang tidak bisa release, serta membandingkan perilaku harian antara keduanya yang didasarkan data rekaman kamera jebak. Penelitian dilakukan di Yayasan Inisiasi Alam Rehabilitasi Indonesia (YIARI) pada bulan Maret hingga Mei 2024. Data yang diambil yaitu perilaku harian yang terdiri dari perilaku aktif, perilaku tidak aktif, perilaku makan, perilaku sosial, dan perilaku abnormal. Pengamatan dilakukan dengan bantuan kamera jebak dengan metode pencatatan one zero sampling dan instataneous sampling. Hasil penelitian menunjukan kukang jawa kandidat release dan yang tidak bisa release menunjukkan aktivitas pada pukul 18.00 WIB, mencapai puncaknya antara pukul 23.00-01.00 WIB, dan berhenti pada pukul 05.00-06.00 WIB. Perilaku yang paling banyak tertangkap oleh kamera jebak yaitu perilaku aktif dan yang paling sedikit yaitu perilaku abnormal dan perilaku tidak aktif. Analisis uji beda Mann-Whitney menunjukan tidak terdapat perbedaan yang signifikan antara perilaku harian individu kukang jawa kandidat release dan individu yang tidak bisa release.

Judul: Perilaku Harian Kukang Jawa (Nycticebus javanicus Geoffroy 1812) di Taman Nasional Gunung Halimun Salak (TNGHS) Jawa Barat
Abstrak: Javan slow loris (N. javanicus) is an endangered species however ecological data and information about its life in nature is limited. According to the IUCN, javan slow loris is one of the critical wildlife status (critically endangered) and listed on Appendix I of CITES since 2007. This study aimed to investigate daily activities of N. javanicus and to assess correlation between climate, moon phase and daily activities of javan slow loris in the Mount Halimun Salak National Park (MHSNP) West Java. Behavioral observations was carried out using a modified method of focal time sampling. Principal Component Analysis (PCA) was used to determine the correlation between the climatic aspects and daily activities. Behavioral observations was conducted on two wild adult females. The most dominant of daily activities N. javanicus were travelling (37.9%), feeding (21.8%), active (12.5%) and foraging (12.3%). N. javanicus preferred natural food items such as nectar (79.9%), sap (16.6%), insects (3.0%) and fruits (0.5%). Correlation climate aspect and moon phase of the daily activities N. javanicus was 59.3%. Phases of the moon gave impact mostly on the daily activities. Nycticebus javanicus is a primate lunar phobia or likely to be active in slightly or no light conditions (dark).

Abstrak: The solution of Schrodinger equations with plasma Coulomb potential in spherical coordinat results solution wave function and energy plasma particle. Electron probability density at Debye length with thermal effect same as ion, which indicates plasma in neutral state. Electromagnetic waves perturbation of an electric field given to result wave function perturbation system. The probability density of plasma particle due to electromagnetic waves perturbation is the largest when an electromagnetic waves frequency 1.41 times the plasma frequency .
