Authors: Rahayu Rahayu , Effendi Muhammad Haris 
Published: September 2022

This study aims to develop student worksheets (LKPD) patterned claim, data, warrant (CDW) on human respiratory system material and find out how teachers respond and student responses and the effect of using LKPD on student argumentation ability. The development model used in this research is addie development model consisting of 5 stages, namely analysis, planning, development, implementation and evaluation. The development of this LKPD uses due diligence based on expert validation of materials and validation of media experts, as well as teacher response and student response. Data analysis techniques used are qualitative and quantitative data analysis. The results of both validators state that LKPD is worthy of testing. Furthermore, the results of the teacher's response also stated that the LKPD is feasible in the trial with a score of 93%. Then the results of the odd and even group student response were obtained from kappa test of 0.673 with high category and correlation test of 0.806 with very strong category. This means that the two groups of students have been in touch and agreed to state that LKPD is worthy of trial. In conclusion, students can understand the problem of claims, data, warrant (CDW) arguments judging by the score of the paired sample t test of 0.000 which means that there is an influence of the use of student worksheets (LKPD) on students' argumentation ability.

This study aims to determine the biological aspects of blacktip sea catfish (Piicofillis dussumieri) in the Barumun River. Fish samples were taken for three months (September 2020-January 2121). The research station was determined by purposive sampling. The fish were caught using 3 gill nets with 1.5 inch mesh. The number of fish caught is counted and then the total length and weight are measured. The data were interpreted in graphical form using the Microsoft Excel 2010 application. The results showed that the growth pattern of blacktip sea catfish was negative allometric with a value of y = 26.3531e0.0796 and R2 = 0.9718. The sex ratio for male and female fish is 3:1. The population density is between 1.20 - 1.6 /100 m2. In conclusion, the growth pattern of P. dusumeiri was negative allometric. The sex ratio (sex ratio) between males and females is not balanced.

This explorative type of research using the purposive sampling method. Fish are caught using a gill net with a mesh size of 1 inch. Analysis of the research data was carried out using the SPSS version 22 application program. The results showed that there were three types of mullet fish caught in the Barumun River, namely Chelon subveridis, Moolgarda perusii and Liza alata. The bivariate correlation test analysis results showed that water transparency and pH showed a positive correlation (+), while temperature, current and salinity had a negative correlation (-). The highest positive correlation value is found in water transparency. In conclusion, the higher the water transparency value, the higher the density of the mullet fish.

Virus Bakteri sebagai Terapi untuk Penyakit Infeksi
Authors: Pratiwi Rina Hidayati 
Published: September 2022

This study aims to provide information related to the role of phages or bacterial viruses in treating infectious diseases. The method used is a secondary literature study from several research publications. The results showed that phage therapy had been medically proven to be superior to antibiotic treatment. Phage families Myoviridae and Podoviridae are the best candidates for phage therapy because most of them have a lytic cycle. Phages with lytic phage types tend to be widely used as biocontrol agents because they are specific and lyse target cells (pathogenic bacteria). In addition, phages do not have genetic material that can be integrated into the human body, so therapy using phages is not virulent in humans. Treatment using phages also does not cause phage resistance to antibiotics. In conclusion, phages' advantages, effectiveness, and host specificity make phages used in various applications to treat infectious diseases.

This study aimed to determine the antibacterial activity of the ethanol extract of the leaves of Tapak Kuda (Ipomoea pes-caprae) against Staphylococcus epidermidis. The method used was Kirby-Bauer for the antibacterial test with various concentrations of ethanolic extract of I. pes-caprae leaf extract: 5 mg/mL, 20 mg/mL, 35 mg/mL, and 50 mg/mL, with five replications. The antibiotic clindamycin was used as a positive control, while DMSO was a negative control. The results showed that after 24 hours of incubation, the zone of inhibition of bacterial growth was demonstrated by the experimental and the positive control groups, while the negative control did not show the zone of inhibition. The diameter of the largest inhibition zone (11.40 mm) was at a 50 mg/mL test concentration, which was indicated as a strong category.

This study aims to analyze the water quality of the Barumun river in Pinang City based on water quality criteria and formulate a pollution control strategy that needs to be implemented. The method used is descriptive and quantitative by analyzing river water quality status based on the pollution index. The results showed that the PI value of Barumun river water ranged from 0.82 to 1.71. The recommended pollution control strategies are: 1) maintaining river border protection zones involving environmental cadres and green communities in monitoring; 2) supervision and control of water pollution along the river; 3) improving monitoring of river water quality and supervision of wastewater discharge into rivers; 4) the granting of a wastewater disposal permit (IPLC) to the river must pay attention to the condition of the capacity of the river's pollution load capacity and enforce environmental laws against business actors who violate the established environmental quality standards. In conclusion, the Barumun River in Kota Pinang has decreased in quality, with the status of water quality being lightly polluted. The recommendations for water pollution control strategies that need to be implemented are progressive strategies.

This study aims to examine the characteristics and environmental factors of turtles' preferences in making their natural nests. The method used is the descriptive quantitative method. The results showed that there were two types of turtles found during the observation, namely the green turtle (Chelonia mydas) and the hawksbill turtle (Eretmochelys imbricata). Measurements and observations of the characteristics of the 14 nesting points showed that the diameter and depth of the green turtle's nest were larger than those of the hawksbill turtle. Both types of turtles have a preference for nesting areas on sloping beaches with temperatures of 28-30ºC and humidity of 76-89%, as well as being around vegetation in the form of sea pine (Casuarina equisetifolia), sea oyster (Gynura sp), sea pandanus (Pandanus odorifer), sea kangkung (Ipomea peltate) and sea hibiscus (Thespesia populnea). In conclusion, temperature, humidity and types of vegetation around the nest determine the turtle's preference in making natural nests for laying eggs.

I started editing the Cambridge Journal of Anthropology at the end of 2017. It seemed like a good opportunity to learn a lot. So I accepted the invitation, with the proviso that I would do it for about three years. But you know how it is when you get attached to something….When I started the job, I defined my role as taking the journal further out of Cambridge. I also wanted the journal to assess all work without regard to an author’s politics, reputation, or professional connections. I think we have stuck to these principles. Now, after about five years, I have decided to hand the editing of the journal over to my colleague Liana Chua. Liana is an amazing anthropologist with the type of care and academic enthusiasm that makes a good editor. It’s her job to figure out the next stage for the journal.
