Effects of NaNO3 and KNO3 in Kosaric fertilizer on the growth of Arthrospira platensis
No full textThis study was carried out to determine whether the replacement of NaNO3 to KNO3 in Kosaric media can give better growth to Arthrospira platensis. The growth of A. platensis in different culture media was which are Kosaric media and Kosaric media with the modifications of NaN03 to KNO3 at concentration of 0.75, 1.25, and 1.75g/L in indoor condition. The pH value for Kosaric media shows the highest reading which is 9.63, followed by both modified Kosaric media with the addition of 1.25g/L KNO3 and 1.75g/L KNO3 which have the same reading of 9.58, and 9.56 for modified Kosaric media with the addition of 0.75g/L KNO3. Cell dry weight is 2.13mg/L for modified Kosaric media, I.78mg/L for modified Kosaric media with the addition of l .25g/L KNO3, 1.61 mg/L. for modified Kosaric media with the addition of 0.75g/L KNO3 and 1.18mg/L for Kosaric media. While for chlorophyll a content, Kosaric media shows the highest value which is 2.79mg/L, followed by modified Kosaric media with the addition of 1.75b/L KNO3 (1.65mg/L), modified Kosaric media with the addition of 1.25g/L KNO3 (1.29mg/L), and modified Kosaric media with the addition of 0.75g/L KNO3 (1.09mg/L). Kosaric media is still the best culture media for culturing of A. platensis. Except for cell dry weight, the modified Kosaric media with the addition of 1.75g/L KNO3 shows the highest reading. The alternative commercial fertilizer that are cheaper than Kosaric media are hoped to replace Kosaric media in culturing A. platensis

No full textIn 2023 the Supreme Court issued Circular No. 2 of 2023. This SEMA was issued
because of the large number of permits for the registration of interfaith marriages
by the courts, even though there was already a prohibition in the previous
regulation, namely SEMA No. 231 of 2019. However, on the other hand, SEMA
No. 2 of 2023 also has substantially the same content as the 2019 SEMA which
discusses interfaith marriages. If, SEMA No. 231 has no effect, then the question is
what impact will SEMA 2023 have on interfaith marriages? Seeing this, there is a
need for legal certainty regarding this issue.
This research is field research. The author uses a normative and empirical
approach. An empirical approach was used to collect data by conducting interviews
with judges. Then the data sources used are primary data taken from judge
interviews, secondary data from statutory regulations and tertiary data.
Looking at the explanation above, it can be concluded that the judges at the
Yogyakarta District Court have the same opinion. This opinion states that interfaith
marriages are a legal event for which applications for permits will not be granted
either with the existence of SEMA No. 2 in 2023 or not. This is because they follow
the essence of existing laws which state that marriage must be in accordance with
the teachings of each religion. However, judges can still use legal discovery
methods in deciding a case regarding an application for registration of an interfaith
marriage. However, this opinion appears to be inconsistent with the Marriage Law,
this is because in several decisions and opinions the judge himself also grants
permission on condition of submission from one of the parties which clearly
contradicts the contents of the Marriage Law
