Abstract

RELEX SMILE menjadi pilihan alternatif selain prosedur LASIK dalam mengobati kelainan refraksi mata. Prosedur ini dinilai lebih aman dan mengurangi resiko pasca operasi. Sehingga banyak orang menggunakan prosedur ini di seluruh dunia. Namun prosedur ini bukanlah operasi mata yang tidak memiliki resiko sama sekali. Tujuan dari penelitian ini adalah untuk mendeskripsikan komplikasi yang terjadi pada prosedur RELEX SMILE. Metode penelitian berupa studi literatur dari beberapa artikel ilmiah internasional dan nasional yang diterbitkan tahun 2012-2022. Hasil penelitian didapatkan beberapa komplikasi yang terjadi selama prosedur yaitu suction loss, opaque bubble layer, bintik hitam, mata kering, ekstasia kornea, diffuse lamellar keratitis, induksi higher-order aberration, transient light sensitivity syndrome, dan kesalahan bias. Komplikasi tersebut dapat dicegah dengan skrining yang menyeluruh, pemberian informasi yang komperhensif pada pasien, ahli yang berpengalaman, disiplin dalam pengobatan dan kontrol pasca operasi.

Abstract

Biological literacy is crucial for students to consider solutions to problems after analyzing them from various perspectives. The purpose of this research is to enhance biological literacy by using ARVi (Augmented Reality Virus) learning media. The research type is a quasi-experiment using a control group pretest-posttest design. The research instrument is a multiple-choice test validated by experts and empirical validation. The expert validation result shows an average score of 3.8, which can be interpreted as the test instrument being valid and suitable for use as a biological literacy measurement tool. The empirical validation result indicates that 3 questions are invalid, while 17 questions are valid as a biological literacy measurement tool. The reliability test result shows that the biological literacy test instrument has a reliability coefficient of 0.835, which can be interpreted as 70% confidence that the instrument can be trusted. The data analysis result shows that the data is normally distributed and not homogeneous. The independent t-test result is a t-statistic of 3.16 with a t-table of 1.98 at an α=0.05. This indicates that there is an increase in results between the control group to experimental group. The paired t-test result is a t-statistic of 15.7 with a t-table of 0.68 at an α=0.05. This indicates that there is an increase in posttest results compared to pretest results. This indicates that the ARVi media can enhance all aspects of biological literacy. The highest increase in biological literacy occurs in the nominal (82%), multidimensional (64%), structural (52%), and functional (32%).

Abstract

Microplastic waste has polluted Indonesian waters, especially at Sepanjang Beach. Microplastics that are not handled properly can enter the digestive tract of aquatic animals, one of which is gastropods. The presence of microplastics must be identified in the gastropod digestive tract, considering that gastropods are also a food ingredient. Sampling was done by purposive sampling and quadratic transects. The length of the transect used is 50m perpendicular to the beach with a quadrant plot measuring 1x1 m. In each plot, 1 individual was taken for each species found. Sample preparation using 15 ml of 10% KOH solution and incubated for 1 night. Optical analysis of microplastics using a stereo microscope at 40x magnification. The most microplastics were found in the Turbo setosus species with 701 particles. The most common form of microplastic found in Gastropods and Bivalvia in the sample was fiber with a total of 2204 particles. Microplastics were also found in seawater on the beach with the form of fiber being the most commonly found, namely as many as 553 particles.
