"In line with the increasing need for higher performance for optical and photonic telecommunications equipment at the lowest possible cost, the need for supporting equipment is also increasing. One of these components is an optical power splitter. This component is needed in network systems to distribute light to other components, especially multi-channel optical power separators to support larger network systems. One of the materials developed as a photonic device material from group III-nitride is gallium nitride (GaN). Besides having a large direct bandgap (3.4eV), GaN also has good resistance to temperature changes. Thus, GaN-based power splitters are an interesting research topic to obtain more improvements, innovations and inventions for future demands. In this research, an optical power splitter design is proposed based on the 1 × 8 multimode interference (MMI) structure. The design has been carried out theoretically using 3D FD-OptiBPM on GaN material. Structural modeling using 300 nm AlN and 200 nm AlGaN as a buffer layer on a sapphire substrate material. Numerical experiments were carried out at the optical telecommunications wavelength at = 1.55 m with the effective refractive index of the coating used =2.279±0.001 and =2.316±0.001. The results showed that the optimum width and thickness of the rectangular input channel and taper-shaped output channel was 4 m, and only supported single mode propagation. From the experimental simulation results, it is shown that the MMI-based optical power separator with a total length of 2010 m and a width of 85 m is the best result. It is also shown that the output power is split almost uniformly into eight output channels with a relative output power of 0.96 on the output channel, 0.28 dB of excess loss and 0.28 dB of power imbalance. 13 dB.

"Penyimpanan obat menjadi salah satu faktor penting dalam pengelolaan obat di apotek karena dengan penyimpanan yang baik dan efisien, pelayanan obat kepada pasien dapat dilakukan dengan tepat guna serta hasil guna. Namun, penyimpanan yang tidak efisien dapat membuat obat cepat rusak atau tidak terdeteksinya obat kadaluwarsa. Tugas khusus ini bertujuan untuk melakukan simulasi penyimpanan obat non padat, alat kesehatan, dan bahan medis habis pakai (BMHP) berdasarkan Peraturan Menteri Kesehatan (PMK) Nomor 73 Tahun 2016 di Apotek Roxy Poltangan. Metode yang digunakan melalui observasi serta simulasi. Tata cara penyimpanan obat non padat, alat kesehatan, dan BMHP dikumpulkan melalui observasi langsung. Selain itu, dilakukan simulasi perbaikan penyimpanan sesuai dengan peraturan di atas. Hasil penelitian menunjukkan bahwa penyimpanan obat non padat terdiri dari sediaan non padat oral yang meliputi sirup dan drop. Sediaan non oral meliputi salep, krim, gel, injeksi dan infus, ovula dan suppositoria, tetes mata, tetes telinga, inhalasi, nebulasi, dan insulin. Penyimpanan obat non padat, alat kesehatan, dan BMHP yang sesuai PMK No.73 Tahun 2016 meliputi penyimpanan di wadah asli pabrik, high alert, penyimpanan sesuai suhu, tempat penyimpanan obat dipisahkan dengan barang kontaminan, dan FEFO. Penyimpanan berdasarkan bentuk sediaan, alfabetis, dan LASA masih belum sesuai. Kesimpulan dari tugas khusus ini adalah penyimpanan obat non padat, alat kesehatan, dan bahan medis habis pakai (BMHP) di Apotek Roxy Poltangan masih belum sesuai namun sudah diperbaiki sesuai dengan Peraturan Menteri Kesehatan (PMK) Nomor 73 Tahun 2016.

Drug storage is an important factor in drug management in pharmacies because with good and efficient storage, drug services to patients can be carried out effectively and efficiently. However, inefficient storage can make drugs spoil quickly or expired drugs cannot be detected. This special assignment aims to simulate the storage of non-solid drugs, medical devices, and consumable medical materials (BMHP) based on Minister of Health Regulation (PMK) Number 73 of 2016 at the Roxy Poltangan Pharmacy. The method used is through observation and simulation. Procedures for storing non-solid drugs, medical devices, and BMHP were collected through direct observation. In addition, storage repair simulations were carried out according to the regulations above. The results showed that storage of non-solid drugs consisted of oral non-solid preparations which included syrup and drops. Non-oral preparations include ointments, creams, gels, injections and infusions, ovules and suppositories, eye drops, ear drops, inhalation, nebulization and insulin. Storage of non-solid drugs, medical devices, and BMHP in accordance with PMK No. 73 of 2016 includes storage in original factory containers, high alert, storage according to temperature, where drugs are stored separately from contaminants, and FEFO. Storage based on dosage form, alphabetical, and LASA is still not appropriate. The conclusion from this special assignment is that the storage of non-solid drugs, medical devices, and consumable medical materials (BMHP) at the Roxy Poltangan Pharmacy is still not appropriate but has been repaired in accordance with Minister of Health Regulation (PMK) Number 73 of 2016."
