Published: September 2020

Tujuan penelitian ini adalah mengidentifikasi pengaruh variasi suhu larutan terhadap struktur lapisan yang terbentuk melalui metode elektroplating. Larutan elektrolit dibuat dengan campuran NiSO4, NiCL2,H3BO3, dan H2O. Elektroplating dilakukan selama 180 s dengan tegangan 4,5 V dan medan magnet 150 G pada arah sejajar permukaan katoda-anoda. Hasil penelitian menunjukkan suhu mempengaruhi ketebalan lapisan, arus listrik, jumlah zat yang terlepas dan terbentuk dan pH larutan. Lapisan paling tebal adalah sampel hasil deposisi pada suhu 40°C dengan ketebalan [(133,8 ± 0,9745)´ 10-5] cm pada pH 4,21. Kemudian yang paling tipis adalah sampel hasil deposisi pada suhu 60°C dengan ketebalan [(59,83 ± 0,6270) x 10-5] cm pada pH 4,18. Ketebalan lapisan yang terbentuk sebanding dengan jumlah zat terlarut dan jumlah arus yang mengalir selama pelapisan berlangsung. The purpose of this study is to identify the effect of temperature variations on the structure of the layers formed through the electroplating method. Electrolyte solution was made with mixture of NiSO4, NiCL2,H3BO3, and H2O. Electroplating was carried out for 180 s on the voltage of 4.5 V and magnetic field parallel to 150 G. The results showed temperature affects the thickness of the layer, electric current, the amount of released and formed substances and the pH of the solution. The thicknest of layer is according to the sample deposited at a temperature of 40°C with a thickness of [(133,8 ± 0,9745)x 10-5] cm at pH of 4.21. Then the thinnest one was according to the sample which was deposited at 60°C with a thickness of [(59,83 ± 0,6270) x 10-5] cm at pH of 4.18. The thickness of the layer is proportional to the amount of solute and the amount of current flowing during the coating. Keywords: Elektroplating, Flim Tipis, Cu/Ni, Suhu Larutan, Magnet Sejajar.

Published: September 2020

Tacca (Tacca leontopetaloides [L.] Kuntze) is a herbaceous plant that grows wild in coastal areas with sandy soil texture. Tacca tuber has a fairly high nutritional content, mainly carbohydrates. At present, the utilization of tacca tuber is limited due to low availability. This research aimed to obtain the fertilizer combination to enhance yield and nutrient content of tacca tuber. The research was carried out in the field using a randomized block design consisting of 6 treatments, namely without fertilizer as a control, manure only (PK), manure combined with inorganic NPK 50% (PKA50), manure combined with NPK 100% (PKA100), manure combined with biofertilizer and NPK 50% (PKHA50), and manure combined with biofertilizer and NPK 100% (PKHA100). The 100% NPK dose is 150: 50: 150 kg ha-1. Biofertilizer used was Beyonic StarTmik with a dose of 25 cc L-1 of water for seedlings soaking, 250 mL for each plant at the age of 1 and 3 months after planting. All those treatments were replicated 5 times. The results showed that the highest yield of tacca tuber was obtained from PKHA50 treatment. Biofertilizer combined with inorganic fertilizer could increase tacca tuber production by 60-100%, but did not affect the nutritional content. The combination of manure, biofertilizer, and NPK 50% can be recommended to optimize tacca tuber production.

Using Biochemistry to Educate Students on the Causal Link between Social Epigenetics and Health Disparities
Authors: Diaz-Cruz Edgar S. , Harland Michael D. , Darensbourg Caleb 
Published: September 2020

Background: While pharmacy education standards require students to recognize social determinants of health (SDOH), there is an opportunity to improve how this is taught in the curriculum. One innovative approach is to educate student pharmacists in a biochemistry course through the integration of topics like epigenetics using SDOH as the framework.
Innovation: A 50-minute educational activity was used to supplement material on the regulation of gene expression, in which epigenetic changes are driven by SDOH. It provided students with a biochemical basis to explain some health disparities, rather than viewing them exclusively as social obstacles to health. The activity employed a mini-lecture, a short video, as well as both small and large group discussion. A reflective paper was used to assess students’ understanding of the topic, and the role of the pharmacist in helping patients prevent diseases caused by epigenetic changes due to social determinants of health.
Findings: A post-activity survey showed that the activity increased students’ perception of knowledge about SDOH, as well as the effect of epigenetic changes on health outcomes. Furthermore, this activity increased students’ awareness about the role that SDOH play in epigenetic changes and challenged students to understand the role that society plays in health outcomes.
Conclusions: The preventable nature of health inequities creates an opportunity to integrate public health into pharmacy education. The integration of epigenetics and SDOH gives the student an opportunity to provide a mechanistic link between social inequities and biochemical processes.

One of the urgent problems of modern surgery continues to be the increasing number of patients with purulent-inflammatory and purulentnecrotic processes of soft tissues – about 60.0 % of patients in the structure of specialized hospitals of a surgical profile. This is due to the adaptation of microorganisms – pathogens of wound infection to existing means for treating wounds. In addition, the number of patients with diabetes mellitus increases annually, and as a result, the number of people suffering from diabetic foot syndrome. Thus, the relevance of developing new modern tools for the local treatment of purulent-necrotic processes of the skin and soft tissues is not reduced.Materials and methods.The material for the study was a highly porous biodegradable sponge (chitosan-collagen) in the ratio of chitosan: collagen 2: 1 with the inclusion of colloidal particles of metallic silver and chymotrypsin. The experiment was performed on 50 Wistar rats that simulated a purulent necrotic wound. During the treatment, the state of the wounds was visually evaluated, the morphological features of the course of the wound process were evaluated after animals were withdrawn from the experiment and the wound material was taken on days 1, 5, 10, 15 and 21, the sections were stained with hematoxylin-eosin and/or according to Van Gieson.Results.By visual assessment, by the 10th day it was noted that necrotic tissues underwent lysis, the wound defect was covered with a scab, swelling of the surrounding tissues was not noted, and on the 21st day of treatment the wound defect was covered with epithelium and had an area of about 3 mm2 with the initial - in 250 mm2. When describing micropreparations, it was noted that on the 10th day the exudation phase passed its peak and the activity of proliferation processes increased from the center of the wound to its periphery and from the granulation surface in depth. On the 15th day, the proliferative phase of inflammation was at its height, and on the 21st day, the proliferation phase was completed and the processes of remodeling of dense fibrous connective tissue began.Conclusion.Based on a visual assessment of the state of wounds and a morphological study, the effectiveness of a chitosan-collagen complex with silver nanoparticles and chymotrypsin was shown to be applied locally to a purulent necrotic wound in an experiment.

Published: September 2020

This legal research uses a conceptual approach and a statutory approach. This research was carried out by inventorying primary and secondary materials, so as to obtain an appropriate analysis and critical review of published legal issues. The purpose of the study was to analyze the dynamics of Large Scale Social Restrictions Policies, especially regarding the Regulation of Minister of Health Number 9 of 2020and analyze various problematic PSBB policies during the pandemic. This study states that the PSBB is different from regional quarantine. On the other hand, the PSBB regulation in the Regulation of Minister of Health Number 9 of 2020 also raises doubts.Then,the Chief of Police's Declaration Mak/2/III/2020 provided strong legitimacy to strengthen the PSBB policy in terms of public compliance.The PSBB policy by the Central and Regional Governments has left various problems. Starting from material errors, contradiction of the article in the Governor's Regulation, and the Governor's Regulation which is not based on the Law above. The solution that can be done is to revise the Government Regulation No. 21 of 2020 and conduct executive review of the Governor's Regulation.
