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.

Abstract

PHBS stands for Clean and Healthy Living Behavior, aiming in the health sector to cultivate clean and healthy living behavior in the form of individuals, groups or the wider community. 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.

Abstract

Mesoscale Convective Complex (MCC) adalah sistem konvektif terbesar bertipe circular dan memiliki masa hidup yang panjang serta mampu menyebabkan terjadinya cuaca buruk. Penelitian ini mengidentifikasi fenomena MCC yang terjadi di Pulau Papua dan sekitarnya pada Desember 2021-November 2022 dengan menggunakan kriteria MCC berdasarkan teori Maddox (1980). Fenomena MCC diidentifikasi berupa distribusi spasial periode musiman dan temporal dengan menggunakan data suhu puncak awan dari Satelit Himawari-8 kanal 13 serta intensitas curah hujan dari data GSMaP. Hasil penelitian menunjukkan pada distribusi spasial terdapat 10 kejadian dengan 5 kejadian di darat dan 5 kejadian di laut. Luasan awan terbesar terjadi di laut mencapai 507.000 km2 yang terjadi pada bulan Maret dan rata-rata nilai eksentrisitas adalah 0.97. Distribusi temporal MCC tergolong aktif di malam hari, matang pada tengah malam hingga meluruh pada pagi hari dengan masa hidup selama 8-14 jam. Hasil pengolahan data dari GSMaP menunjukkan nilai curah hujan yang terjadi mencapai 64.1 mm/jam. Intensitas curah hujan yang terjadi di darat tergolong sedang hingga sangat lebat, sedangkan yang terjadi di laut tergolong sedang hingga ekstrem.

Abstract

This study aims to examine the impact of liquidity, solvency, and profitability on the financial performance of manufacturing companies in the food and beverage sector listed on the Indonesia Stock Exchange (IDX) for the years 2021–2024. The study employs a quantitative explanatory methodology utilizing secondary data derived from audited financial statements. Researchers utilized a purposive sampling strategy to choose 16 organizations as research samples. The examination of the data included classical assumption tests, multiple linear regression, partial t-tests, simultaneous F-tests, and the coefficient of determination. The findings indicate that liquidity (Current Ratio), solvency (Debt to Equity Ratio), and profitability (Return on Assets) each exert a positive and significant influence on financial performance as assessed by Return on Equity. At the same time, the three independent variables have a big effect on financial performance, with a good correlation (R = 0.828). This means that 68.6% of the changes in ROE can be described by CR, DER, and ROA, while the other 31.4% is due to other factors that are not part of the model. These results show how important it is for businesses to keep their capital structure healthy, manage their liquidity at the right level, and make more money in order to increase shareholder value and keep their business going
