Abstract

Synthesis of SnO2 has been carried out by using extract of Cnidoscolus aconitifolius leaf as a natural capping agent. The synthesis aims to determine the effect of the use of a capping agent on the crystallinity and the size of crystals. The mass variations of the capping agent used were 5, 10, and 15 gram using the hydrothermal method at relatively low temperature (95-100°C). The synthesized of SnO2 were characterized using FTIR (Fourier Transform Infra Red Spectroscopy) and XRD (X-Ray Difraction). The results of FTIR characterization show the stretching vibration absorption band of Sn-O-Sn in the spectrum with and without capping agent at wave number 599 cm-1 and 599.333 cm-1 . XRD diffractogram shows that SnO2 without a capping agent and using a capping agent has relatively the same crystallinity. Mass variations of 5, 10, and 15 gram resulted in crystals measuring 14.37 nm, 13.75 nm, and 11.78 nm and SnO2 without capping agent measuring 15.93 nm. The results showed that the Cnidoscolus aconitifolius leaf solution could be used as a natural capping agent to produce SnO2. The results of SEM characterization show that aggregate reduction can be seen in the addition of Japanese papaya (Cnodoscolus aconitifolius) capping agent.

Abstract

SnO2/ZnO composites were synthesized using the hydrothermal method using Japanese papaya (Cnidoscolus aconitifolius) leaf extract. This study aims to determine the effect of using Japanese papaya leaf extract (Cnidoscolus aconitifolius) on the formation of crystallinity and morphology in synthesizing SnO2/ZnO composites. Synthesis was carried out with variations in mass of 5, 10, and 15 grams using the hydrothermal method for 12 hours at 160°C. The results of X-Ray Diffraction (XRD) characterization show that wide diffractogram peaks are identified as the peaks of the SnO2 compound with a tetragonal structure and sharp peaks are identified as the peaks of the ZnO compound. The Fourier Transform Infrared (FTIR) characterization shows the peak wave number of 665 cm-1 which is the Sn-O-Sn strain and the peaks at wave numbers 598 cm-1 and 501 cm-1 which are the Zn-O strain. Characterization of Scanning Electron Microscopy (SEM) in the synthesis of SnO2/ZnO composites after adding Japanese papaya (Cnidoscolus aconitifolius) leaf extract had relatively reduced particle size and aggregate formation compared to no extract. The best effective mass of Japanese papaya leaf extract (Cnidoscolus aconitifolius) is the mass variation of 15 grams with 28.49 nm crystals.

Abstract

Demam Berdarah Dengue (DBD) merupakan jenis penyakit akut yang disebabkan oleh virus dengue yang tergolong Arbovirus (Arthropod borne V). Jumlah kasus DBD yang dilaporkan pada tahun 2020 tercatat sebanyak 108.303 kasus. Kasus DBD ini sering menimbulkan kejadian luar biasa (KLB). Tujuan penelitian ini untuk melihat bagaimana profil penggunaan obat pada pasien demam berdarah dengue (DBD) dewasa di Rumah Sakit X Bengkulu dan kategori DRPs yang terjadi pada pasien DBD di Rumah Sakit tersebut. Penelitian ini dilakukan secara retrospektif dengan mengambil data rekam medik tahun 2023 dan dianalisis secara deskripfitif dengan menggunakan metode menurut Cipolle. Sampel diambil dengan metode total sampling dengan beberapa kriteria inklusi. Didapatkan 54 sampel yang sesuai kriteria inklusi. Hasil penelitian ini didapatkan penggunaan obat pada pasien demam berdarah yaitu pemberian infus ringer laktat 98,15% dan infus ringer asetat (Asering) 1,85% Sedangkan hasil identifikasi DRPs 23 kasus yaitu indikasi tanpa obat 14 kasus (25,9%) dan obat tanpa indikasi 8 kasus (14,8%)
