After implementing various policies to deal with covid-19, which were still considered ineffective, the Government of Indonesia is now trying to implement a mandatory vaccination policy for all of its citizens. However, the program's success depended on the perceptions and beliefs that developed in the community regarding the covid-19 vaccine itself. This study aimed to examine the Health Belief Model (HBM) effect using the variables of perceived susceptibility, severity, benefits, and barrier s on covid-19 vaccination intention. By using a quantitative method that was cross-sectional and involving 452 respondents who were taken using the purposive sampling method. After being analyzed using Partial Least Square Structural Equation Modeling (PLS-SEM), the results of this study showed that perceived susceptibility, severity, and benefits had a positive influence on covid-19 vaccination intention. At the same time, the perceived barrier showed a negative effect. In the end, this study provided a theoretical model of HBM in predicting behavioral intention, which in turn, predicted behavior. On the other hand, this research also provided a starting point for research into the interest in vaccination against covid-19 in Indonesia.

To resolve the health crisis caused by coronavirus disease (COVID-19), the Indonesian government is trying to implement a mandatory vaccination policy for all Indonesians. It was just that the success of this policy is largely determined by acceptance preceded by the public intention to be vaccinated, in which public perception plays a major role in determining intention. This research, therefore, aimed to evaluate and examine the role of perceived risk, benefit, and susceptibility on the COVID-19 vaccination intention. By using a cross-sectional approach, this quantitative study involved 98 participating respondents who were determined by the purposive sampling method. The results of this study finally found and proven that perceived risk (coefficient β=0.290 and T-value 2.456 with p-value=0.011), perceived benefits (β= 0.394 and T-value 3.873 with p-value=0.000), and perceived susceptibility (β=0.233 and T-value 3,230 with p-value=0.001) had a positive and significant effect on the COVID-19 vaccination intention.

Tariffs or price control has been a controversial subject in recent years. The debate between legal experts and economists is still a hot topic in any discussion. Tariff control regulated in the work creation omnibus law seems to be a topic that must be discussed again regarding this regulation’s urgency. Are specific prices so impressive that the government can intervene in regulating them? This article examines the urgency of rules regarding price controls to create a healthy competitive environment. After conducting a critical literature review, it was analyzed with critical analysis and looking at the objective of competition law was to maximize welfare by protecting competition. The results in this article indicated that the government could only intervene in regulating price-fixing only if companies’ pricing could harm the country’s economy and consumer welfare. The government, therefore, had an interest in regulating the price ceiling. Meanwhile, the price floor, which was believed to be pro-consumer and could promote consumer welfare had no interest and should not have been limited by the government.

Covid-19 outbreak, which is considered to be still not optimal enough, the Indonesian government seems to be risking its efforts on a mandatory vaccination policy. However, this intervention will not succeed without the participation of the community in the form of their interest in receiving the Covid-19 vaccination. Therefore, by involving 422 Muslim respondents who live in the Special Region of Yogyakarta, the main objective of this study is to focus on the factors that influence or predict halal Covid-19 vaccination intention. Thus, it is clear that this research is a quantitative descriptive study with a cross-sectional survey. The results of the descriptive analysis of this study then explained that the majority of respondents were Muslim people who were male as much as 217 (51.42%), aged 19 - 24 years (38.39%), domiciled in the city of Yogyakarta (38.63%) and worked as students as many as 188 people (44.55%). While the results of quantitative analysis using the Partial-least square structural equation modeling (PLS-SEM) method in this study revealed that halal Covid-19 vaccination intention was influenced by factors such as attitude toward halal vaccination (β = 0.541, t-value = 10.199, -value = 0.000), subjective norm (β = 0.196, t-value = 3.913, -value = 0.000), and social norm (β = 0.156, t-value = 3.374, -value = 0.001) positively and significant. In addition, the theoretical and practical implications based on the results of the research are also discussed in this study.

This study aims to reveal how the role of the police in handling the case of the traditional hot air balloon flight in Ponorogo which includes law enforcement, obstacles experienced, and future concepts based on the perspective of the police. Therefore, this research will be juridical and empirical by using a statutory and qualitative approach. After processing data using qualitative analysis, the results of this study reveal that the police have the authority to enforce the law against anyone who violates the order, safety, or laws and regulations. It's just that in matters of investigation, the police hand over the authority to the Civil Investigating Officer (PPNS) in the field of aviation. In addition, the police in each sector in Ponorogo Regency also have difficulties or obstacles, the majority of which are making tradition and lack of knowledge from the community and the lack of the role of local government as the main factors. Therefore, even the police, in this case, do not expect that this tradition should be eliminated, it's just that in the future there must be strict supervision and control so that the practice of this hot air balloon flight tradition does not endanger the safety and security of anyone and does not violate applicable laws.

Predatory pricing has long been termed like a dragon or a unicorn because the practice is often considered irrational and therefore impossible to find or at least unlikely to work. However, the case that befell PT Conch South Kalimantan Cement broke the stigma in Indonesia, which was legally proven to practice predatory pricing through the Business Competition Commission Council (KPPU) Case Decision Number: 03/KPPU-L/2020. Considering that predatory pricing is complicated to prove because it requires certain elements to be fulfilled, this research then aims to analyze the predatory pricing elements, which became strong reasons that underlay the KPPU Council's determination of PT Conch South Kalimantan Cement as a predatory business actor so that it is entitled to be punished with billions of rupiah. By applying the normative method with a statutory, conceptual, and case approach through primary and secondary legal materials, which were analyzed by qualitative and prescriptive analysis, this study ultimately found the results that the elements in the form of business actors, supply, goods, selling at a loss or fixing a very low price, eliminating or shutting down the business of its competitors, the relevant market, and causing monopolistic practices and/or unfair business competition have become the ratio decidendi of the KPPU Council in determining the practice of predatory pricing. These reasons can then be used as decisions on similar issues in the future.
