CHARACTERIZATIONS ON BENDING EFFECT ON CUSTOMIZED SPLITTERS USING VARIOUS RADII OF ELLIPTICAL-SHAPED BLOCKS
SUPIAN, L. S
Macro-bending effect unto polymer optical fiber (POF) based splitters study is done to analyse the performance and characterizations using several bending radii of geometrical blocks that hold a customized prepared polymer fiber splitter. A pair of etched fibers with similar core diameters are attached to the ellipse-shaped blocks built using matching refractive index material where the blocks were built with various bending radii. The tapered fibers were lapped closely with some forces exerted upon them in order to stimulate the splitting of modes between the two fibers. This study is done by experimental set-up where each of the splitter ports is connected with optical power meter to measure the power output while pressure is exerted. Characterization is executed in order to investigate and analyse which bending radius gives the most optimize splitting ratio with considerable low loss for the particular splitter prepared. As for normal force of 0.3 lbF, the optimum splitting ratio with low loss is specified having bending radius, Rc, of 13 mm whilst for external force of 3.0 lbF, bending radius is found to be 19 mm. Small bending radius stimulates the
radiation of rays into the second fiber while larger Rc gives longer coupling length that optimize the splitting ratios. Efficiencies between simulated values and experimental values are also analysed.

2-D Modes Analysis of Micro-Ring Resonator:In case of chemical vapor sensing
Ramza, Harry
This paper describes 2-D modes analysis on the waveguide structure. Micro – Ring Resonator formation was simulated to able the chemical vapor detection by using COMSOL Multiphysics application. We present the simulation of mode analysis from a Micro-ring Resonator as sensing the chemical vapor. By implementing the device parameters. We have seen from the simulator that the optical mode is handled equally within the ring. Using the variation of effective refractive index, our simulator result of ring resonator generated the mode analysis in two-dimension perspective. We conclude that the ring resonator device has potential for generating the certain wavelength.

Design and Simulation of MEMS Electrostatic Resonator for Ammonia Gas Detection Based on SOIMUMPs
Ba Hashwan, Saeed S
The analytical modeling, design, and simulation of micromachined MEMS resonator for ammonia gas detection
is presented in this paper. The MEMS resonator is designed to be vibrated electrostatically using interdigitated comb fingers. The demonstrated device is designed to be capable to carry micro-ring resonator and vibrated in-plane laterally to enhance the sensitivity of the gas detection. This MEMS resonator working principle is based on the changes in the output signal wavelength due to the change in the effective refractive index introduced by the ammonia gas. The resonant frequency of the actuator and the pull-in voltage have been calculated theoretically and found to be 11.15 kHz and 79.7 V respectively. The design and simulation of the micromachined microresonator has been carried out using CoventorWare software. Furthermore, the mathematically modeled results were verified using the finite element analysis software and the result shows a good agreement within 1.06% error between the modeled and simulated frequencies where the modeled and the simulated frequencies are found to be 11.15 kHz and 11.27 kHz respectively.

The first proposed of fiber to the home (FTTH) protection unit for clients scattered placement
Ramza, Harry
This paper describes the design and analysis of protection schemes that it is not regular customers’ location in optical communication system network. Distance and number of customers with the design of optical point protection unit achievements are recognized as the user for a series of rings from CAPU-Ring 1 (Customer Access Protection Unit). CAPU-Ring 1 is made as a safety point of optics that will be placed on the prior user. This system is an optical spot that will be placed in a ring circuit for use in placement of clients scattered. Proposed construction of a series with a protection channel architecture is about designing CAPU-Ring 1 as optical nodes, condition and repair damage to the circuit, the power budget calculations, design in the simulation, and analysis of the node to node. Parameters outlined in this discussion are the relationship of each node optical output power, improving the system of the eye diagram to the distance and also increase the system working against the maximum optical node. Characterization of ring network protection architecture can be identified from the results of a simulation study.

Pola Asuh Balita Stunting Usia 24-59 Bulan Pada Masa Pandemi COVID-19
Hermawan, Saputra
Indonesia termasuk salah satu negara dengan “tiga beban malnutrisi”, sebelum adanya pandemi COVID-19. Tujuh juta
anak di Indonesia mengalami stunting. Sebagian dari total ibu hamil mengalami anemia. Stunting dapat terjadi akibat
pola asuh balita yang tidak sesuai dan pola makan balita yang tidak seimbang. Penelitian ini bertujuan mengetahui pola
asuh terhadap balita stunting usia 24-59 bulan pada masa pandemi COVID-19 di wilayah kerja Puskesmas Kecamatan
terpilih Kota Depok Jawa Barat Tahun 2020. Penelitian dilakukan di wilayah Puskesmas Kecamatan Pengasinan, yaitu
Kelurahan Pengasinan dan Bedahan. Pelaksanaan penelitian ini mulai bulan Juli-Agustus tahun 2020. Metode yang
digunakan dalam penelitian ini adalah dengan menggunakan metode kualitatif. Hasil penelitian menyatakan bahwa
masih banyak ibu balita yang kurang tepat dalam hal pola asuh balita. Mulai dari kurangnya pemahaman tekait ASI
Eksklusif dan MPASI, pentingnya imunisasi dasar lengkap, vitamin A, dan praktik pemberian makan serta kurang
tepatnya pola pemberian makan pada balita. Selain itu praktik pelayanan kesehatan di Puskesmas Pengasinan sudah
cukup baik selama masa pandemi stunting tetapi pelayanan kesehatan khusus balita stunting dianggap kurang karena
selamapandemi tidak ada pelayanan kesehatan khusus yang diterima balita stunting. Diharapkan untuk mengevaluasi
kinerja kader-kader posyandu. Selain itu, nakes juga perlu memberikan mentoring dan coaching pada kader, sehingga
meningkatkan kapasitas kader posyandu.
