Abstract

Informasi prakiraan cuaca khususnya di wilayah Tangerang penting untuk diketahui, karena frekuensi banjir akibat cuaca ekstrem semakin meningkat. Dalam NWP, teknik asimilasi dikembangkan untuk memperbaiki kondisi awal model. Penelitian ini bertujuan untuk mengetahui pengaruh asimilasi data satelit cuaca WRF-3DVAR dalam memprediksi hujan di wilayah Tangerang tanggal 21 Januari 2019. Empat eksperimen yang dijalankan pada penelitian ini adalah asimilasi dengan Himawari-8 kanal IR (DA-IR), Himawari-8 kanal WV (DA-WV), gabungan sensor AMSU-A dan MHS (DA-AM), serta tanpa asimilasi (CTRL). Hasilnya, semua eksperimen menghasilkan prediksi yang baik untuk parameter curah hujan, RH, dan kecepatan angin. Namun, pada parameter suhu udara, semua eksperimen menghasilkan nilai error yang melebihi nilai toleransi. DA-IR menghasilkan perubahan terbesar pada suhu udara dan RH. Sementara itu, DA-WV memberikan perubahan terbesar pada rasio pencampuran uap air, ketinggian geopotensial, dan kecepatan angin. Secara keseluruhan, DA-IR merupakan eksperimen yang paling baik dibandingkan yang lainnya, baik secara verifikasi titik maupun spasial. Eksperimen asimilasi diurutkan dari performa terbaik adalah DA-IR, DA-WV, kemudian DA-AM. Meskipun DA-AM tidak memberikan hasil signifikan, eksperimen ini memberikan estimasi terbaik pada kecepatan angin dibandingkan yang lainnya.

Abstract

Acute exacerbation of Chronic Obstructive Pulmonary Disease (COPD) is a worsening of stable COPD/respiratory symptoms. The 2020 Global Initiative for Chronic Obstructive Lung Disease (GOLD) shows erdostein, carbocysteine, and n-acetylcysteine can reduce the risk of acute exacerbations in COPD. The aim of this writing is to determine and compare the effectiveness and safety of erdostein, carbocysteine, and n-acetylcysteine in acute exacerbations of COPD. The scientific review takes the form of a literature review by searching for data using books, journals and websites. Sixteen articles were obtained with the results that erdosteine, carbocysteine, and n-acetylcysteine reduced the risk of acute exacerbations of COPD. The best effectiveness results depend on the dose of the drug and the length of use. The best reduction in the risk of exacerbation was oral erdostein, dose 900 mg daily for 10 days (39.1%), Carbocysteine 1500 mg daily for 6-12 months (p < 0.00001) and n-acetylcysteine 1,200 mg/day for 3 months (p<0.05). Erdostein was well tolerated and there were no treatment-related side effects. The frequency of side effects of respiratory tract infections was not detected for erdostein, but for carbocysteine it was found to be 0.56% and NAC 10.85%. Two patients dropped out of the study because of gastrointestinal disturbances related to carbocysteine side effects. The conclusion of this scientific review is that the use of erdostein 900 mg/day for 10 days has the best effectiveness in reducing COPD exacerbations, then carbocysteine 1500 mg/day for 6-12 months, then n-acetylcysteine 1200 mg/day for 3 months.

Abstract

This study seeks to examine the impact of total asset turnover (TATO), current ratio (CR), profit growth, and business size on stock returns in food and beverage manufacturing firms listed on the Indonesia Stock Exchange (IDX) from 2019 to 2023. The research adopts a quantitative methodology, including multiple linear regression analysis. We acquired data from the annual financial statements of the enterprises that constituted the study's samples. The findings indicated that the Total Asset Turnover (TATO) and Current Ratio (CR) factors had a significant and beneficial influence on stock returns. The profit growth variable exerts a positive and significant influence on stock returns, however the firm size variable does not demonstrate a meaningful impact on stock returns. This study concludes that the company's financial performance, particularly regarding asset utilization efficiency and liquidity capacity, significantly influences stock returns in the food and beverage manufacturing sector.

Abstract

MSMEs (Micro, Small and Medium Enterprises) are businesses that have a fairly high role, especially in Indonesia, which is still classified as a developing country. With the large number of MSMEs, there will be more job opportunities for the unemployed. In addition, MSMEs can be used as a source of income, especially in rural areas and low-income households. Lack of knowledge about the taxation and bookkeeping system for MSMEs is one of the reasons why MSME actors in Sunggal District, Deli Serdang Regency are reluctant to calculate, pay and report their income. In the socialization carried out by the PKM team, it was found that almost all MSME actors in Sunggal District, Deli Serdang Regency did not understand and did not know how to calculate, pay and report taxes on MSMEs. In addition, MSME actors also still do not use a good bookkeeping system to support MSME business records. The PKM team intends to carry out PKM activities with an approach method through counseling and socialization regarding the taxation and bookkeeping system for MSMEs. Through this PKM activity, it is hoped that it will be beneficial for MSME in Sunggal District, Deli Serdang Regency in the form of increasing knowledge and understanding related to the taxation and bookkeeping systems for MSME.

PHBS must be cultivated especially to children, for example through educational institutions. The purpose of counseling is carried out to prevent the disease is that children are taught to wash their hands. The counseling was conducted at Galilee Hosana School, Jl. Bunga Terompet No.30, Padang Bulan Selayang II, Kec. Medan Selayang, Medan City on December 6, 2023. As a result, 4th grade students of SDS Galelia Hosana can understand and practice hand washing properly and correctly. So it can be concluded that PHBS counseling on hand washing practices in grade 4 students is useful and important for health.
