<p><strong>Herbs are plants with moist stems that grow wild along roadsides or on the unmaintained ground. Herbs are more commonly associated with plants that are harmful to civilization, even though they have numerous uses in life, including traditional medicine, ornamental plants, and contextual instructional resources. People are unaware of herbs and plants categorized as herbs, which is one of the reasons why they are considered hazardous plants. A mangrove forest is a type of forest with a tidal environment; plants that may grow in mangrove forests are characteristic vegetation, notably salt-tolerant plants. The goal of this research was to describe the plant variety in the Muara Aluh-Aluh Mangrove Area. The data was gathered in the 500-meter-long Muara Aluh-Aluh Mangrove Area, which was divided into ten locations separated by 50 meters. A plot of 1 m x 1 m with as many as 4 pieces was made at each place using the line transect method and oriented diagonally. The quantity and varieties of herbaceous plants found in the plot were counted as samples. According to the findings of the study on herbaceous plant diversity in the Muara Aluh-Aluh Mangrove area, there are 21 different varieties of herbaceous plants with a diversity index of 2.66, putting them in the medium diversity category.</strong></p><p><em><strong>Keywords</strong> -<strong> </strong>Diversity, Herbs, Mangroves, Muara Aluh-Aluh</em></p>

Currently, rice farming land is getting narrower because it is pressed for housing. Ways are needed to utilize narrow land to develop a rice farming system, including hydrogenic farming, which is an organic cultivation system by planting rice on humus soil in plastic cups planted in a row of paralon pipes above fish ponds, integrating a hydro system (water circulation) nutritious and organic systems (without chemical fertilizers). This Community Partnership Program aims to deal with the problems experienced by service partners, namely the Self-help Agricultural and Rural Training Center "Bengkel Mimpi" in Malang Regency which carries out hydroganic rice cultivation, namely how to obtain alternative sources of electricity so that financial expenditures for electricity can be increased. So far, only state electricity company can save more/reduce, so that the solution and output target implemented in overcoming these problems is in the form of a solar power plant which is used to drive 12 hydraulic water pumps. The method of service is action research: discussion, design and application of solar power plants. After going through technical calculations, 6 100 wp solar panels were installed, complete with support brackets, 3 100 AH batteries, 1 solar charge controller, 1 3000 WA inverter, 12 water pumps. The advantage of this solar power plant is the design aspect of the solar panel support bracket which is made attractively resembles the shape of a sunflower. The test results have been carried out in sunny conditions this solar power plant produces 2,144 Watt Hours. The output of this Community Partnership Program can be used as a model for alternative sources of electricity in other villages nationally, especially on hydrogenic and hydroponic agricultural lands which are located far from the state electricity network.

SARS-COV-2 Neutralizing IgG Antibodies in Patients Recovered from COVID-19 in a Hospital-Based Study: From Predictions to Reality
Authors: Khan Hamzullah , Bari Fazli , Mohammad Tahir , Jan Rizwanullah 
Published: February 2022

Background: The duration and immunity nature in form of antibodies to COVID-19 is still not clear. But so far we know that an immune response protects the individuals from future illness for some specific time. The presence or absence of immunity tells us about the future transmission of illness.
Objectives:

To determine the frequency of antibodies to COVID-19 after three weeks of negative PCR report.
To predict the association of the antibodies values with severity of the disease the patient had in recent past.

Material and methods: We did a cross sectional study in department of Pathology on 36 patients recovered from COVID-19 from 3rd July 2020 to 31st July 2020. Antibodies level was measured by electro-chemiluminescence immunoassay using Roche Cobas E411 Chemistry Analyzer for which commercial kits of Roche diagnostics were used as per the instructions of the manufacturer, in respondents after 3 weeks of a negative PCR report.
Results: The mean with standard deviation for numerical variables i.e. (age and antibodies) was 34+11 years and 34.52+12.71 respectively. 29(80.55%) were males and 7(19.45%) females. The mean antibodies level was statically significantly higher in patients with age less than 50 years (p-value: 0.01). Patients who had severe symptoms at time of being reported positive by PCR had significantly higher antibodies cut off values as compared to asymptomatic positive patients (p-value:0.04). Clinically sever Covid-19 patients positively moderates with an increase in the values of the post infection anti SARS-COV-2 antibodies supported by an interaction term with (β=0.388**; ΔR²=0.126, p-value=0.02). Male gender supported by the results of an interaction term with (β=0.388**; ΔR²=0.126, p-value=0.02) had sever disease as compared to female.
Conclusion: The higher anti SARS-COV-2 antibodies were reported in patients with age <50 years and in patients who had severe symptoms or history of hospitalization during the infectious period. There was a statistically significant relationship supported by the interactions terms of higher post infection antibodies level with male gender, an increase in age and with history of sever disease or hospitalization.

Published: February 2022

Abstract:
Background:
Since the emergence of COVID-19 in Wuhan, China, it has claimed many lives and global economic losses. Healthcare workers have been the most exposed group in this pandemic. This study aims to determine the prevalence of anti-SARS-CoV-2 antibodies among the employees of Islamabad Medical and Dental College and its allied hospital Akbar Niazi Teaching Hospital.
Methodology:
All members of the staff and faculty of Islamabad Medical and Dental College and allied hospital Akbar Niazi Teaching Hospital were encouraged to get tested for SARS-CoV-2 antibodies and 294 employees volunteered for the study from 23rd July to 30th July,2020 through Elecsys® Anti-SARS-CoV-2 (Immunoassay for the qualitative detection of IgG antibodies against SARS-CoV-2 in human serum and plasma).
Results:
Out of 284 volunteers, 87 (30.6%) were SARS-CoV-2 antibody positive, with the mean antibody level in seropositive individuals recorded as 24.4418 ± 25.3494. , housekeeping and sanitary workers were the most affected; 14 (48.3%) were antibody positive, while 15 (51.7%) were antibody negative. After housekeeping and sanitary staff, the second most affected workers were lab technicians (37.1% were positive compared to 62.9% negative). Fever, loss of taste or smell and breathing difficulty were the most significantly associated symptoms with COVID-19 antibody seroprevalence as suggested by the p values 0.003, 0.004 and 0.032 respectively. Out of the 13 PCR positive participants (in the preceding 3 months) 10 (76.9%) showed positive antibody in their serum and 3 (23.1%) had not developed antibodies.
Conclusion:
Seroprevalence of SARS-CoV-2 antibodies was estimated to be high among the healthcare staff (30.6%), with the housekeeping and sanitary staff to be the most affected employees, probably due to the breach of personal protection. Fever, loss of taste or smell and breathing were strongly associated with seropositivity of SARS-CoV-2 antibodies.
