Introduction: Indonesia is ranked the 4th most populous country in the world. Since Covid19 is highly transmissible from human to human, Indonesia might suffer a long period of the Covid19 pandemic ...than other less-populous countries. This study aimed to find the correlations of tropical climate, population density and confounding factors with Covid19 progression in Indonesia from March to August 2020. Methods: The climatological data, population density, laboratory testing, and the confirmed Covid19 cases were statistically analyzed. The correlations between each data were performed with Pearson’s Correlation Coefficient using a Statistical Package for the Social Sciences. The values of statistical significance were considered at 95% and 99% confidence intervals. Results and Discussion: Indonesia recorded more than 1,315 confirmed Covid19 cases in almost all provinces (30 out of 34) during the dry season (March to August 2020). During the early pandemic, DKI Jakarta and East Java have been the epicenters of the pandemic in Indonesia. Humidity and precipitation have a weak negative correlation, while the temperatures have a weak positive correlation. Population density and laboratory testing have a strong positive and significant correlation with the cumulative confirmed Covid19 cases. Conclusion: Our study indicates that tropical climate less affects the cumulative Covid19 case in Indonesia than population density and laboratory testing capacity.
The demand for stevia extract consumption as an alternative sweetener that contains stevioside with zero-calorie is increasing. However, dark color and high tannin content from stevia leaf extract ...causes a disturbing aftertaste and reduces interest in consumption. Therefore, the purification process is a mandatory step to be done. Several studies on purification methods show the best approach by adsorption using bentonite. However, natural bentonite has limited adsorption capacity and low selectivity. An activation with acid and high temperature is expected to increase the adsorption capacity of color and its selectivity on maintaining the stevioside at the extract. This study aimed to obtain the optimum acid concentration and temperature for the activation using the Response Surface Method (RSM) experimental design and its application to the purification of stevia leaf extract. Based on the parameter of methylene blue number, the most optimum concentration of H2SO4 used for activation was 0.17 N for both natural bentonite. The heating temperature was 358°C for Na-bentonite and 481°C for Ca bentonite. The maximum adsorption capacities of activated Na and Ca-bentonite were increased from 15.65 and 38.23 mg g-1 to 197.72 and 169.52 mg g-1, respectively. The best adsorbent used for purification is Ca-activated, which increased extract clarification up to 81.37% at 655 nm and 86.64% at 410 nm compared to natural Ca bentonite. It also reduced tannin up to 97.46% and was more selective to recover 50.64% stevia content in the solution, which was higher than other previously reported studies.

Climate change affects the agricultural sector, which has an impact on droughts or floods. Ecological agriculture is expected to be an adaptation method for reducing losses due to climate change. ...This study aims to describe the characteristics of farmers, ecological rice cultivation practices, and the relationship between the two parameters. The research in Kendayakan Village, Terisi District, Indramayu Regency, involved 60 farmers surveyed using accidental sampling techniques in February 2022. The data collected include farmer characteristics (age, education, land area, land ownership status), length of farming, sources of farming knowledge, participation in groups, and rice cultivation practices. Data on the application level of ecological agricultural practices were analyzed descriptively and tested usin the Spearman Rank correlation between farmer characteristic variables and rice cultivation practices. The results showed that farmers were of productive age, with a low level of formal education but experienced and active in local organizations. The level of application of farmers' ecological agriculture is moderate. The return of straw, tillage, and control of plant pests are the components of cultivation that are least following the principles of ecological agriculture. Internal factors of farmers that correlate with the components of ecological rice cultivation are age, education, length of farming, source of farming knowledge, and land ownership status.

Implementation, development is not a stand-alone entity, but rather integrated and becomes a unit with existing development components. The purpose of this study is to examine legal concepts through ...legal development as an effort to realize regional competitiveness. The type of research that will be used is Juridical-Normative Researchers. This research in conjunction with the juridical-normative method in this study uses the results of this study to show that regional competitiveness correlates with the development of national law as stated in Law Number 17 of 2007 concerning the National Long- Term Development Plan that was previously listed in the Outlines of State Policy. The second generation legal theory of development through legal concepts is not only a means of development, but also as a means of renewing the bureaucracy. The development of laws that will improve the competitiveness of the nation needs to pay attention to three important things, first, the development of quality and beneficial legislation. Realizing the competitiveness of each region in Indonesia, which of course will have an impact on the welfare of the State, of course, must be accompanied by legal development both in the substance of the law, legal structure and legal culture.
