Abstract

In the Covid Pandemic 19, sharia cooperatives must be a solution for the welfare of their members and the UMKM that they support so that they can move up in class, but how if it is difficult to access, therefore sharia cooperatives must be digital-based and include collaborating with fintech. This study tries to answer the problems that occur, strategies, and stakeholders involved in the development of Islamic cooperatives in collaboration with sharia fintech in Indonesia using the Interpretive Structural Model (ISM) approach. The core problem faced in developing sharia cooperatives in collaboration with sharia fintech is the lack of education and promotion of Islamic financial institutions collaboration, especially in sharia cooperatives with sharia fintech (E9), which initially became competitors to financial institutions because they were very flexible and fast and have become OJK's instructions that fintech must collaborate with financial institutions including sharia ones. Furthermore, it can be suggested for legislators, actors and drafter to constantly monitor and improve the process in the context of the progress and welfare of cooperatives and SMEs in Indonesia.

Abstract

The horizontal axis wind turbine (HAWT) design with low wind speed requires blade geometry selection. The analysis uses the potential flow panel method and the integral boundary layer formulation to analyze wind flow around the airfoil. The blade design with the blade element momentum (BEM) theory has an aerodynamic coefficient value along the blade. Power wind calculates to model the wind shear pressure at each blade. This research aims to determine the wind turbine rotor based on the performance, including the power coefficient, tip speed ratio, power, and rpm. The simulation uses an airfoil NACA 4412 which has optimal coefficient lift (Cl) = 1.92 at 190 pitch of angle, coefficient drag (Cd) = 0.0635 at 130 pitch angle and Cl / Cd = 155 at tilt angle = 40. Five models of 2.5 m diameter blades with different angles for each chord. The test results show that the change in the speed ratio affects the power coefficient so that the optimal power coefficient on NACA 4412 in experiment 5 is 0.56, and change in rotation per minute affects the output power so that the rotation per minute and the optimal power in experiment 4 with a value of 374 rpm and 553 W.

Abstract

The aim of this research is to recognize the income variable, the economic activity, and the family size determination, also differences in the location of living against oil palm farmer consumption in Labuhanbatu Regency, Indonesia. The Method that used to analyze the data is Multiple Linear Regression model, specified in Least Square Dummy Variable (LSDV) method. The estimation result found that all of independent variable positive significantly influenced the food consumption. Otherwise, the negative one significantly influenced the non-food consumption outcome. The estimation result also found that the level of consumption for many kinds of urban food was fewer than hinterland society food consumption about Rp.1.248.000. However, the urban consumption more excessively than coastal area society about Rp.1.323.000. While the level of consumption outcome for many kinds of non-food urban consumption larger than non-food hinterland consumption about Rp.2.248.000. Also larger than non-food coastal society consumption about Rp.1.376.000. The variation of independent variable capability to explain the food consumption about 92,5 % and non-food consumption outcome about 87,4 %. The specification models were appropriated which the model free of multicollinearity and Heteroscedasticity classic assumption collision.

Abstract

Business failure in the economic system causes various economicactors to potentially become rent-seekers in an imperfect political system. Sugar isan agricultural commodity that, thus far, is a public good that needs governmentregulation. This study aims to determine the social capital of Indonesia's sugarinterest groups and to determine the dominant variable in Indonesia's sugarindustry. Materials and Methods: This research uses a type of explanatory researchthat has a high relationship level because it not only has independent andcomparative values but also serves to explain and predict the relationship with aqualitative approach between variables. Relationship analysis using DecisionExplorer version 3.3 software. Results: analysis of the relationship of and variablein the sugar industry, the more variables involved in the loop, the most importantrelationship between variables in the loop, the most important loop is loop 4consisting of economic rent, the refined sugar market, entrepreneurs in food andbeverage, lobbying, government. Conclusion: It is concluded from the findings ofthis study that the social capital of Indonesia's sugar interest groups consists of 9loops, Almost every variable has a weak strength to social capital and leads todamage.

Abstract

Body Mass Index problem is becoming a double burden in Indonesia, including among older people. Nowadays, the elderly face a high index of BMI due to some risk factors and it is leading to other non-communicable diseases. This research aimed to examine the correlation between some determinants and obesity among older people in Sintang Regency, West Kalimantan. 358 elderly aged 46 to 65 years participated in this study selected by the total sampling method. The independent variables in this study were knowledge, activity, food intake, sex, attitude, age, the history of obesity, and obesity breeds, type contraception, and the duration of sleep. The multivariate analysis was found that knowledge, activity, food intake, age, and duration of sleep were significantly associated with obesity among the elderly. The preventive and promotive approach is needed to treat the obesity prevalence.

Abstract

This study aims to determine Buzzers' existence and the Buzz Marketing strategy carried out by Buzzers during the 2019 Presidential Election on Twitter. The method in this study used qualitative research with Sostac P.R Smith's analysis. As a result, 1) the Buzzer's existence in the 2019 Indonesian Presidential Election contest was formed at the end of 2018. The formation of a Professional Buzzer was carried out through a recruitment process held by several legal companies with a predetermined payment system; 2) In carrying out Buzz marketing, Buzzer has arranged plans to distribute political content. Buzzers use a variety of political strategies to amplify political messages. Then, the political messages are spread using a minimum of three or more accounts to engage in a conversation. Through systematic Buzz marketing planning, political messages that are informative, persuasive, and instructive systematically and intensely to Twitter netizens make the results more optimal. However, Buzzer still needs to formulate political content that is more attractive to Twitter netizens, such as avoiding old content that uses political narratives containing SARA elements, hoaxes, hate speech, and other propaganda.

Abstract

Herbs utilization spare new opportunities to handle dental health issues. Bangun-bangun leaves have chemical components which are strongly related to the prevention of the occurrence of dental plaque. The current research aimed to observe the effect of using mouthwash made from bangun-bangun leaves extract with the concentration of 40% and 80% towards the occurrence of dental plaque on the students of III A and III B classes in Private Madrasah Ibtidaiyah Annur Medan, North Sumatera. The research used quasi-experimental method through the Pre-Post Test with Control Group design. Analysis of this research was conducted initially through normality and homogeneity tests on the variants. If the variable is normally distributed then it means that the variable is not homogenous, leading to the testing of Difference between Two Means (t test) through two parties’ test of t’-test which was independent sample t-test. Through this research, researcher obtained t count of (57.20) > t table (1.987). Therefore, based on the basic of decision making through distinguishing t count and t table, then H0 was rejected and H1 was accepted. It means that there was difference on the treatment results between before and after using the 80% bangun-bangun leaves solution. Furthermore, the t count value (45.73) > t table (1.987), which based on the basis of decision making through distinguishing the t count and t table values was that H0 was rejected and H1 was accepted. It means that there was difference on the treatment results between the use of 40% and 80% of bangun-bangun leaves solution. It can be concluded that both of the uses of 40% and 80% of bangun-bangun leaves solution affected significantly on the prevention of students’ dental plaque occurrence.
