Abstract

In dengue-endemic countries such as Indonesia, Zika may be misdiagnosed as dengue, leading to underestimates of Zika disease and less foreknowledge of pregnancy-related complications such as microcephaly. Objective: To assess the attitudes of frontline physicians in a dengue-endemic country toward testing for Zika infection among patients with dengue-like illnesses. Methods: A cross-sectional online survey was conducted among general practitioners (GPs) in Indonesia. The survey assessed their attitude and also collected sociodemographic data, characteristics of their medical education, professional background, and workplace, and exposure to Zika cases. A two-step logistic regression analysis was used to assess possible variables associated with these attitudes. Results: A total of 370 GPs were included in the final analysis of which 70.8% had good attitude. Unadjusted analyses suggested that GPs who were 30 years old or older and those who had medical experience five years or longer had lower odds of having a positive attitude compared to those who aged younger than 30 years and those who had medical experience less than five years, OR: 0.58; 95%CI: 0.37, 0.91 and OR: 0.55; 95%CI: 0.35, 0.86, respectively. No explanatory variable was associated with attitude in the fully adjusted model. Conclusion: Our findings point to younger GPs with a shorter medical experience being more likely to consider testing for Zika infection among their patients presenting with dengue-like illnesses. Strategic initiatives may be needed to enhance older or longer-experienced physicians' capacity in diagnosing Zika infection.

Abstract

Vaccine hesitancy, defined as the reluctance or rejection in receiving a vaccine despite its availability, represents a major challenge to global health efforts aiming to control the ongoing COVID-19 pandemic. Understanding the possible factors correlated with COVID-19 vaccine hesitancy using a refined well-informed approach can be helpful to address the phenomenon. The current study aimed to evaluate COVID-19 vaccine acceptance rates using four hypothetical scenarios of varying levels of vaccine efficacy and safety profiles in ten Asian, African and South American countries. These scenarios included: 95% efficacy and 20% side effects (Vaccine A), 75% efficacy and 5% side effects (Vaccine B); 75% efficacy and 20% side effects (Vaccine C) and 50% efficacy and 5% side effects (Vaccine D). This study used a self-administered online survey that was distributed during February–May 2021. The total number of study respondents was 1337 with countries of residence as follows: India (21.1%), Pakistan (12.9%), Sudan (11.2%), Nigeria (9.3%), Iran (8.2%), Bangladesh and Brazil (7.9%), Chile (7.7%), Tunisia (7.6%), and Egypt (6.2%). The overall acceptance rates for COVID-19 vaccination were variable based on varying degrees of safety and efficacy as follows: 55.6% for Vaccine C, 58.3% for Vaccine D, 74.0% for Vaccine A and 80.1% for Vaccine B. The highest levels of COVID-19 vaccine acceptance were observed in Brazil followed by Chile across the four different safety and efficacy scenarios. The lowest COVID-19 vaccine acceptance rates were reported in Egypt and Tunisia for the low safety scenarios (20% side effects), and the low efficacy scenario (50% efficacy). The study revealed the potential effect of vaccine safety and efficacy on the intention to get COVID-19 vaccination. At the same efficacy level, higher possibility of side effects caused a large drop in COVID-19 vaccine acceptance rate. This indicates the importance of accurate communication regarding vaccine safety and efficacy on attitude towards the vaccine and intentions to get vaccinated. Regional differences in COVID-19 vaccine acceptance were observed with the Middle East/North African countries showing the lowest rates and the South American countries displaying the highest vaccine acceptance rates.

Abstract

Vaccine hesitancy is considered as one of the greatest challenges to control the ongoing coronavirus disease 2019 (COVID-19) pandemic. A related challenge is the unwillingness of the general public to pay for vaccination. The objective of this study was to determine willingness-to-pay (WTP) for COVID-19 vaccine among individuals from ten low-middle-income countries (LMICs) in Asia, Africa, and South America. Data were collected using an online questionnaire distributed during February - May 2021 in ten LMICs (Bangladesh, Brazil, Chile, Egypt, India, Iran, Nigeria, Pakistan, Sudan, and Tunisia). The major response variable of in this study was WTP for a COVID-19 vaccine. The assessment of COVID-19 vaccine hesitancy was based on items adopted from the World Health Organization (WHO) Strategic Advisory Group of Experts (SAGE) vaccine hesitancy scale constructs. In this study, 1337 respondents included in the final analysis where the highest number of respondents was from India, while the lowest number was from Egypt. A total of 88.9% (1188/1337) respondents were willing to pay for the COVID-19 vaccination, and 11.1% (149/1337) were not. The average WTP for COVID-19 vaccination was 87.9 US dollars ($), (range: $5-$200). The multivariate model analysis showed that the country, monthly household income, having a history of respiratory disease, the agreement that routine vaccines recommended by health workers are beneficial and having received the flu vaccination within the previous 12 months were strongly associated with the WTP. Based on the country of origin, the highest mean WTP for COVID-19 vaccine was reported in Chile, while the lowest mean WTP for the vaccine was seen among the respondents from Sudan. The availability of free COVID-19 vaccination services appears as a top priority in the LMICs for successful control of the ongoing pandemic. This is particularly important for individuals of a lower socio-economic status. The effects of complacency regarding COVID-19 extends beyond vaccine hesitancy to involve less willingness to pay for COVID-19 vaccine and a lower value of WTP for the vaccine.

Abstract

Provinsi Aceh merupakan salah satu wilayah yang berlokasi di zona subduksi aktif sehingga menyebabkan wilayah tersebut sering mengalami gempabumi. Penelitian ini bertujuan menentukan tingkat seismisitas wilayah Aceh menggunakan metode Gutenberg Richter. Nilai parameter dari hubungan antara frekuensi dengan magnitude gempabumi (Log N = a - bM) diestimasi dengan metode statistik least square, yang kemudian digunakan untuk menghitung indeks seismisitas, periode ulang gempabumi, dan tingkat resiko gempabumi di wilayah Aceh. Data yang digunakan dalam penelitian ini adalah dataset kejadian gempabumi di wilayah Aceh dari bulan Januari 1929 sampai dengan bulan Desember 2017 yang secara geografis terletak pada 2,0°–6,0°LU dan 98,0°–92,0°BT dengan magnitude > 1 dan kedalaman ≤ 60 km. Wilayah penelitian dibagi menjadi 24 grid dengan ukuran 1°×1°. Hasil analisis data menunjukkan bahwa wilayah Aceh memiliki tingkat seismisitas yang tinggi, diindikasikan dengan nilai a yang bervariasi dari 2,07 sampai dengan 7,31 dan nilai b yang bervariasi dari 0,40 sampai dengan 1,22. Penelitian ini juga menunjukkan bahwa Aceh Singkil merupakan wilayah yang memiliki tingkat resiko terjadinya gempabumi yang paling besar untuk magnitude M ≥ 7, M ≥ 8, dan M ≥ 9 dengan lama waktu ulang masing-masing 23,6; 65,6; dan 182,6 tahun. Aceh Province is one of the regions located in active subduction zones, causing the region to experience frequent earthquakes. This study focuses to determine the seismicity level for the Aceh region using the Gutenberg Richter method. The parameter values of the relationship between frequency and magnitude of earthquakes (Log N = a - bM) were estimated using the statistical least square method, which was then used to calculate seismicity index, recurrence interval of earthquakes, and earthquake risk level for the Aceh Region. The data used in this study is the earthquake dataset collected from January 1929 to December 2017 that located at 2.0° – 6.0° LU and 98.0° – 92.0° BT with magnitudes > 1 and depth ≤ 60 km. The research area was divided into 24 grids with a size of 1°×1°. The analysis results show that the Aceh region has a high seismicity level, indicated by a-value that varies from 2.07 to 7.31 and b-value that varies from 0.40 to 1.22. The study also shows that Aceh Singkil has the largest earthquake risk level for M ≥ 7, M ≥ 8, and M ≥ 9 with a recurrence interval of 23.6, 65.6, and 182.6 years respectively.

Abstract

Cabai merah merupakan salah satu komoditas pangan yang memiliki nilai ekonomi tinggi. Perubahan harga cabai merah yang berfluktuasi dapat dipengaruhi oleh peningkatan konsumsi masyarakat yang berpotensi mengakibatkan terjadinya inflasi. Salah satu cara pengendalian terhadap inflasi adalah dengan pengontrolan harga komoditas pangan termasuk cabai merah. Tujuan penelitian ini adalah meramalkan harga cabai merah di Kota Banda Aceh tahun 2021-2022 dengan metode Triple Exponential Smoothing. Hasil penelitian menunjukkan bahwa pada tahun 2021-2022, harga cabai merah di Kota Banda Aceh diperkirakan akan cenderung tinggi pada bulan Mei hingga Desember dengan puncak tertinggi terjadi pada bulan Juni. Pemerintah Kota Banda Aceh dan TPID perlu melakukan operasi pasar pada saat harga cabai merah diprediksi tinggi sebagai salah satu upaya dalam menjaga stabilitas laju inflasi di Kota Banda Aceh.

Abstract

Setiap perusahaan diharuskan mempunyai modal yang memadai dalam pemenuhan kebutuhnnya. Perusahaan yang sehat akan memiliki dana cadangan dalam operasionalnya. Karena perusahaan memiliki kebutuhan yang bersifat jangka pendek maupun jangka panjang. Kebutuhan tersebut berupa operasional pegawai, pajak, kredit atau hutang dan lain sebagainya yang perlu dibayar. Namun dalam pengelolaan hutang atau kredit perusahaan, dibutuhkan kecermatan sehingga dapat meminimalisir dana kredit tersebut. Karena pada dasarnya penggunaan hutang akan memiliki implikasi pada pembiayaan dan waktu. Modal kerja adalah bagian dari masalah urgen yang sangat berpengaruh bagi perusahaannya, karena pada dasarnya perusahaan dalam ketika mengelola modal adalah bagian dari aktiva. Dimana modal dikeluarkan untuk menarik keuntungan atau laba dari perusahaan. Laba adalah ukuran dari perusahaan dalam menilai kegiatan usaha dagangnya. Jika perusahaan mengeluarkan biaya besar dan tanpa diimbangi dengan penjualan yang besar pula, maka kemungkinan perusahaan itu akan mengalami kerugian, namun jika biaya usaha diimbangi dengan penjualan yang besar pula, memungkinkan perusahaan untuk mendapatkan keuntungan atau laba. Kata Kunci: Hutang Lancar, Modal Kerja dan Laba.

Abstract

Sisa Hasil Usaha (SHU) adalah pendapatan koperasi yang diperoleh dalam satu tahun buku dikurangi dengan biaya, penyusutan, dan kewajiban lainnya. Besarnya sisa hasil usaha yang diperoleh menunjukkan bahwa koperasi dikelola secara profesional. Perolehan Sisa Hasil Usaha yang besar diharapkan supaya koperasi dapat tumbuh dan berkembang, semakin besarnya sisa hasil usaha yang diperoleh koperasi tentu akan meningkatkan kesejahteraan para anggota dan masyarakat pada umumnya. Walaupun demikian, kesejahteraan anggota tidak hanya diukur dari perolehan sisa hasil usaha yang besar saja akan tetapi bentuk pelayanan yang baik, pemberian bunga yang kecil, dan kesejahteraan sosial lain yang diperoleh anggota. Kondisi Sisa Hasil Usaha yang selalu menurun diakibatkan kurangnya kesadaran anggota membayar kewajiban hutangnya pada tepat waktu mengakibatakan perolehan sisa hasil usaha mengalami penurunan. Tujuan utama koperasi yaitu ingin menjadi lebih baik lagi demi kesejahteraan anggota dan keberlangsungan koperasi dengan harapan anggota sadar akan tanggung jawabnya membayar kewajiban hutangnya sesuai dengan kesepakatan. Akan tetapi, pada kenyataannya masih banyak anggota yang belum sadar akan kewajibannya membayar hutang tepat waktu. Kata kunci: Asset, Sisa Hasil Usaha (SHU), Modal Pinjaman, Koperasi

Abstract

The Financial Services Authority regulation No.46/POJK.03/2015 states that the calculation of Systemic Important Score (SIS) of a bank uses the same weighting for all three indicators: size, interconnectedness, and complexity. It disowns the possibility that one those indicators may give more contribution in determining the data structure of SIS assessment component than the others. This study offers an alternative weighting system to calculate SIS. The weighting system is based on eigenvectors of Principal Component Analysis by starting with standardizing the data. The simulation results show that the order of banking systemic levels in Indonesia from the highest are banking BUSN Devisa, Persero, Asing and BPD, Campuran, and BUSN Non Devisa.
