IMPLEMENTASI KEBIJAKAN ADAPTASI KEBIASAAN BARU DI MASA PANDEMI COVID-19 (Studi Pada Masyarakat Pelaku UMKM di Sekitar Lingkungan Kampus IAI Darussalam Kelurahan Tanjung Rema Martapura)

The Indonesian government policies in implementing "adaptation of new habits" during the Covid-19 pandemic are received various responses from the public. Some people are very supportive of the implementation because they are aware of the benefits and know the dangers of Covid-19. Furthermore, the others are still ignorant and do not respond well to the government's policy for various reasons. Among them are the economic reason and a lack of understanding of the Covid-19 risks and their implications for human health. The government also begin vaccination across the country to prevent the spread of the virus. This study uses a quantitative-descriptive method. It aims to determine the implementation of the "adaptation of new habits" in the community of the MSME businesspeople around the Darussalam Islamic Institute Martapura campus during the Covid-19 pandemic period. This study concludes that most of them obeyed the new Covid-19 health policies implemented by the government because most of them understand the dangers of Covid-19 transmission.

Portraying "Village Regulations" among Urban Community in Campago Guguak Bulek Nagari, Mandiangin Koto Selayan, Bukittinggi, West Sumatra

Migrant workers usually come to a city for economic reason as cities are still deemed to provide much available economic opportunities. Urban communities, on the other hand, typically preserve village regulation that they specifically formulate in dealing with comers like what occurs in Bukittinggi, West Sumatra. On the basis of it, this article aims to portray the village regulation taking sample at the Campago Guguak Bulek Nagari, Mandiangin Koto Selayan, Bukittinggi, West Sumatra. The research problems are on the current village regulation from its establishment, form, dissemination, sanction, stratification of legal subjects, and the effect as well as how the regulation will look like in the future. This is a qualitative normative research using in-depth interview with comers who directly deal with local regulations as well as local communities as the one who preserve the regulation. It found that regulations at Bukittinggi emphasize protection of the local economy and socio-cultural aspect. More specifically, it aims to regulate life together, protect rights and obligations as well as social institutions, maintain safety and order, and improve community welfare. This all make the village regulation deserve for future preservation. (Salah satu alasan perantau mendatangi sebuah kota biasanya adalah faktor ekonomi. Kota-kota besar hingga hari ini masih dianggap menawarkan banyak peluang ekonomi. Masyarakat kota, di sisi lain, biasanya memiliki berbagai aturan khusus bagi para pendatang seperti yang terjadi di Bukittinggi, Sumatera Barat. Dari situ, artikel ini ingin memotret hubungan antara aturan lokal di Bukittinggi dengan para pendatang di situ, khususnya di Kelurahan Campago Guguak Bulek, Mandiangin Koto Selayan, Bukittinggi, Sumatra Barat. Pertanyaan penelitian ini adalah seputar peraturan kampung yang berlaku mulai dari pembentukan, bentuk-bentuk, sosialisasi, sanksi, subyek hukum, dan efeknya. Selain itu, akan dilihat juga bagaimana prediksi akan ‘nasib’ peraturan ini di masa mendatang. Penelitian ini bersifat normatif-kualitatif dengan wawancara mendalam kepada para pendatang maupun komunitas lokal sebagai salah satu metode penggalian data utamanya. Hasilnya menunjukkan bahwa aturan-aturan tersebut menitikberatkan pada perlindungan sosial—ekonomi lokal, utamanya perihal aturan-aturan hidup berdampingan, perlindungan hak dan kewajiban, pranata sosial, jaminan keamanan dan ketentraman, serta peningkatan kesejahteraan. Inilah yang membuat peraturan tersebut layak untuk tetap berlaku hingga di masa mendatang)

Preliminary Assumptions for Identification of the Common Hamster (Cricetus cricetus) as a Service Provider in the Agricultural Ecosystem

The common hamster is a critically endangered species, but it is also perceived as a pest. Searching for an economic reason for its protection can be an argument to prevent its extinction. The purpose of this paper is to reveal the identification services provided by hamsters in the agricultural ecosystem and the determination of their correlation with human welfare. We propose the methods that can be applied for this purpose, and we check if the knowledge of the species is sufficient in order to use available methods for estimating the value of the services. The common hamster is a provider of supporting, regulating, and cultural services. Estimating their value is difficult because (1) available knowledge on the species’ ecology requires an update, in many aspects, due to changes to agricultural practices that have taken place since the 1970s (e.g., assessment of actual losses to cereal, vegetable, or root crops), and also extending by context, enabling the economic valuation of services (e.g., determination of impact range on various habitat components); it is also necessary to identify the correlations between profits and losses caused by this species; (2) there is a low level of public knowledge on the presence of hamsters and their role in the ecosystem. Education, primarily for consumers, followed by the promotion of hamsters as an umbrella and key species for agricultural areas, may result in the development of cultural services, which will increase the economic value of the services provided by hamsters.

The Relevance of Liquidity and Country Risk to Euro-Denominated Bonds and the Influence of ECB Monetary Policy

This paper investigates the main determinants of euro denominated corporate bond yields, then analyses the “country effect” by focusing on economic reasons for the strong link between country and corporate yields. It also examines the potential impact of monetary policy of the European Central Bank (ECB) on corporate bond yields on the days of Governing Council meetings. A sample of 1,762 corporate euro-country bonds is analyzed for the period May 2005 – January 2012 using OLS panel data. The economic reason for the strong link between countries and corporate yields is investigated up to 2017. We find that idiosyncratic liquidity and risk have a crucial impact on bond yields, but yields are also strongly influenced by the risk of the corresponding sovereign bonds. Finally, we show that unexpectedness component of ECB policy also exerts a strong short-term effect.

Impact of intergenerational transfers on fertility

On the theoretical basis of the "generational economy" the article describes the "model of overlapping generations" and "life cycle model" as the cause of the existence of intergenerational transfers. The classification of approaches to their study is carried out. Based on the exchange model (the concept of childbearing as a long-term investment in future transfers from adult children to elderly parents) and the theory of substitutions (crowding out private transfers by public social systems), the "elderly security hypothesis" is highlighted as a possible socio-economic reason for the demographic transition. Based on the works of A. Cigno, a theoretical review of this theory is made using the concepts of ^substitution effect» and «free rider effect». According to the works of R. Fenge and B. Scheubel, the "income effect" and "price effect" are defined as the key parameters for testing this hypothesis. An overview of the existing scientific and practical works on the topic of research is made, highlighting methods and results on the following examples: Italy after World War II, Germany at the turn of the 19th and 20th centuries, Brazil in 1991-2000, Hungary in 19502006, 34 OECD countries in the 1990s and the consolidated data for 121 countries at present. The author has carried out his own empirical test of the «hypothesis of elderly security» in the countries of the world on the basis of UN and OECD statistics. Coverage, social security spending, replacement rate, mandatory premium rate, and an increased risk of poverty among older people support the safe aging theory of upward intergenerational transfers from children to parents. But the internal rate of return of pension systems and the average income of older people support the competing hypothesis of top-down intergenerational transfers from parent to child. It is concluded that, with a relatively low standard of living of population, intergenerational transfers go from children to parents, but when a certain level of national welfare is reached, the movement of transfers changes to the opposite direction.

Reverse Migration Determinant Factor: A systematic literature review

Reverse migration in Malaysia is a relatively new emerging phenomenon where the migrants have intentionally chosen to return to their hometown for better living. Thus, there is a considerable demand to investigate the determinants that lead to these changing trends of population mobility in Malaysia. This study adopts the systematic literature review to identify the determinant factors of reverse migration. The aim is to analyze empirical studies to determine factors in reverse migration. Consequently, the findings discovered several determinants namely following family, career, environment, economic reason, quality of life, and social aspect as the driving factors towards achieving subsistence living.

The Bay Leaves Active Compounds and Its Lipid Oxidative Inhibition Activity in Bulk Cooking Oil

Cooking oil is one of the basic human needs. Improving the quality of bulk cooking oil is necessary because it is related to economic reason. The bulk cooking oil have a lower price than brand package oil, of course. Based on these reasons, research is needed on the use of antioxidants to improve the quality of bulk cooking oil. This study aims to identify the phytochemicals of bay leaves extract through TOF profiling, analysis of iodine number and acid number of bay leaves extract against bulk cooking oil. TOF profiling was carried out to see whether bay leaves had chemical compounds that supported antioxidant activity which had an impact on the inhibition of fat oxidation. The research consisted of 4 stages: 1) extraction and fractionation of bay leaves, 2) TOF profiling of bay leaves extract, 3) application of bay leaves extract to bulk cooking oil, 4) analysis of iodine and acid numbers. Profiling TOF of the bay leaves extract showed 3 peaks : C6H13NO5 (cyclohexanol, galactose, and fructose derivatives), C11H14O5 (pyran and furan), andC11H19NO3 (morpholine derivate). According to SNI, the acid value maximum 0.6 mg KOH/g. Iodine value minimum is 45 g I2/ 100 mL (SNI 3741 : 2013). Based of this data standart, this study recommended use bay leaves extract in concentration 0.80%. The addition of bay leaves extract as much as 0.80% showed an iodine number of 48.2 g I2/100 mL and an acid number of 0.34 mg KOH/g where the positive control TBHQ showed an iodine number of 48.7 g I2/100 mL and an acid number of 0.19 mg KOH/g.

Clinical-economic evaluation of a screening for Pompe disease in children in the local conditions

Pompe disease with late onset (PDLO) can’t be diagnosed in time due to common symptoms with several neuro-muscular diseases. Screening and diagnostic measures could lead to efficacy enzyme replaced therapy (ERT) with alglucosidase alfa with aim of severe complications prediction. Screening has a nominal cost, so evaluation of it’s clinical-economic reason to use is important, especially in the local conditions. Materials and methods. Dynamic of expenditures for PDLO in case of screening in kids from risks groups has been performed, including treatment with alglucosidase on time in 12-months horizon — cost of illness. Direct and non-direct costs were calculated in case of diagnostic on time and for non-diagnosed patients, cost-effective ratios were calculated and compared in both cases. Results. The analysis showed a 10 % reduction in the total cost per year with 50 % coverage of children at risk group and 18 % (837 mln RUR) — in case of 100 %-coverage with screening on PDLO. These changes in costs are associated with a significant reduction in the burden on outpatient and inpatient care units. Cost-effective ratio in case of early treatment with alglucosidase alfa was less than in non-diagnosed group on 18,1 %. ERT had main cost in diagnosed group, and costs of complications and disability were main in nondiagnosed group. Conclusion: Health Care system expenditures are expecting less in case of screening on PDLO in risks groups.
