Abstract

Ale-ale shells are popular shellfish in the Ketapang coastal area. The local community uses the shellfish a lot as food processing, one of which is in the form of fermented products. In the fermentation process, the nutritional content of course will be different from fresh ale-ale because it has gone through the preservation process. In this study, several work procedures were carried out for proximate testing including measuring pH, determining water content, ash content, protein content, fat content and carbohydrate content. The proximate content in fermented products is different and tends to decrease, such as protein content, fat content, carbohydrates. This is due to the difference in preparations between fresh ale-ale and fermented ale-ale products. The purpose of testing proximate levels is to determine the difference in proximate content between fresh ale and ale ale that is processed by fermentation.

Abstract

Law as a tool in carrying out social control in this case requires the help of criminology, which is the science that studies crime as widely as possible. In legal provisions in Indonesia, the discussion on age-related insult or defamation is regulated in Article 310 paragraph (1) of the Criminal Code (KUHP), such as the case in Decision Number: 1014/Pid.SUS/2020/PN.Mdn. In this study the method used to collect data by means of literature study. Literature study is a data collection technique by conducting a review study of books, literatures, notes, and reports that have to do with the problem being solved. In this study, the primary legal material for legislation is Law Number 19 of 2016 concerning Amendments to Law Number 11 of 2008 concerning Information and Electronic Transactions of the Criminal Code. As for this research, secondary legal material is in the form of publications on law and official articles from print media and electronic media and then arranges them systematically to answer the problems in Decision Study Number 1014/Pid.SUS/2020/PN.Mdn. One of the crimes that often occur in society is insult and defamation through electronic documents or called cybercrime, which is regulated in Article 27 paragraph 3 in conjunction with Article 45 paragraph 3 of Law no. 11 of 2008, although the Criminal Code (KUHP) also regulates insults or defamation, it is regulated in Article 310 paragraph (1) of the Criminal Code (KUHP).

Abstract

This research uses quasi-experimental research. The population in this study were students of Class XI MIPA at SMA Negeri 1 Sunggal T.P. 2019/2020. This research aims to make it easier for students to achieve learning goals in understanding concepts and solving linear programming problems using a Think Pair Share (TPS) type cooperative model and a scientific approach. The research results show that the learning model that has been designed is good for use. The tcount value for the problem solving test is 5.0350 while ttable = 1.667, which means tcount > ttable, meaning it is accepted or rejected, so it is concluded that learning using the think pair share type cooperative model is better than the scientific approach to linear programming problem solving in Class XI Sunggal 1 Public High School T.P. 2019/2020. Keywords: Cooperative Think Pair Share Type, Scientific Approach, Concept Understanding

Abstract

Background: Human Immunodeficiency Virus (HIV) is a viral infectious disease that attacks the immune system or white blood cells (lymphocytes). HIV, which belongs to the Retroviridae family, is lymphatic, which can damage the specific immune system, namely T-helper lymphocytes or Cluster of Differentiation 4 (CD4). The CD4 count is normal when it is 500–1400 cells/mm3, which is usually the determinant of whether a patient is infected with HIV or not. Objective: This study aims to assess the comparison of CD4 counts in HIV-TB patients before and after ARV and OAT treatment at Dr. Pirngadi Medan City. Methods: Observational analysis research with a cross-sectional design was conducted at RSUD Dr. Pirngadi Medan City in September 2022. The sample for this study was 20 patient records from the medical records of RSUD Dr. Pirngadi, Medan City. The data were analyzed using an unpaired t-test. Results: The results of the study showed that the most HIV-TB pulmonary patients at RSUD Dr. Pirngadi Medan City were aged 36-45 years (50.0%). The majority of male patients (90.0%) and the domicile of most patients in Medan City are in the Medan Tembung sub-district (15.0%). The results of the unpaired t-test obtained a p-value of 0.022, meaning that there was a significant difference between the CD4 count before and after ARV and OAT treatment in HIV-TB patients at RSUD Dr. Pirngadi Medan City. Conclusion: There were significant differences in CD4 counts before and after ARV and OAT treatment in HIV patients with pulmonary TB co-infection at Dr. Pirngadi, Medan City.

Abstract

This research is an experimental research with the type of research used is quasi-experimental research (pseudo-experiment) which aims to determine whether there are differences in the mathematical problem solving ability of students taught with the contextual teaching and lerning model with a humanistic paradigm with the contextual teaching and learning model with a local wisdom paradigm. The population in this study is the VIII grade of Maria Goretti Kabanjahe Junior High School T.P 2019/2020. After testing the posttest data on students' problem solving ability statistically, it was found that -count < table or tc> table with dk = 40 and dk = 60, namely (-0.997) < table (1.671) so that Ho was rejected and ha was accepted. So it can be concluded that the mathematical problem solving ability of students taught with Contextual Teaching and Learning with Local wisdom paradigm is higher than the mathematical problem solving ability of students taught using Contextual Teaching and Learning with Humanistic Paradigm on the topic of two variable linear equation system.
