Pendidikan Kesehatan Prokes Masa Covid-19 Varian Baru Pada Kelompok Pengajian di Dusun Kepel, Lojejer, Wuluhan

The purpose of this service is to increase partners' knowledge and awareness in recognizing and preventing the spread of the new variant of Covid-19. Until now, Covid-19 has undergone several mutations. For the latter is the emergence of the Arcturus variant. Covid-19 cases have also continued to increase since they were first discovered in Indonesia, although they are not as violent as before. This condition makes partners neglect to take care of themselves so they don't get infected. Because you feel safe, you don't need to worry anymore. This phenomenon is a problem that must be addressed immediately, because the Covid-19 case, which is currently in a sloping period and has experienced a very significant decline, is no guarantee that it will be safe from the emergence of new variants and their transmission. The new variant of Covid-19 cases in Mitra has not been detected at this time. However, cases of coughs, colds and fever in partners are still common. For this reason, to prevent Partner negligence which can be fatal, it is necessary to conduct health education for Partners. Health counseling to partners was held on Saturday, 13 May 2023 which was attended by 19 people. This activity was carried out by two lecturers and two students from the Faculty of Health Sciences, Muhammadiyah University of Jember. The results of health education show an increase in knowledge about the new variant of Covid-19 Arcturus, both understanding, causes, signs and symptoms, prevention and treatment. Before counseling 89% of partners had insufficient knowledge, and after counseling 79% of partners had good knowledge about Covid-19. In addition, partners are taught the 7 steps to wash their hands properly. And partners are able to practice it sequentially correctly.

Total Mikroba pada Tanah yang Dicemari Sludge Limbah Pabrik Kertas dengan Perlakuan Pupuk Guano

There are 83 paper mills in Indonesia recorded by the Indonesian Pulp and Paper Association (APKI) spread throughout the archipelago. These paper companies produce products in the form of tissues, various types of paper, and other fiber-based products. Efforts to meet the needs of this raw material produce innovations in the form of using waste paper by separating the ink from the fibers contained in the paper, this separation process is known as the deinking process. Paper mill solid waste can be in the form of sludge, pith, and biosludge. Sludge is a factory solid waste originating from the settling of WWTP which consists of 90% solid and 10% liquid. Paper mill waste in the form of solid waste from sludge contains heavy metals such as Cd, Cr, Pb, Ni, Cu, and Zn. These metals can be overcome by bioremediation using guano fertilizer which is an organic material derived from bat droppings which is rich in phosphate. The purpose of this study was to determine the microbial population in soil contaminated with paper mill sludge waste treated with guano fertilizer. The parameters observed in this study were the total number of bacteria and fungi that survive in soil contaminated with paper mill waste as an indication that the land can still be planted with certain plants. This research was conducted at the Laboratory of Soil Biology, Laboratory of Soil and Land Fertility Agrotechnopark – Faculty of Agriculture – University of Jember. This study used a 3x3 two factorial experimental design with the basic pattern of Randomized Block Design (RAK), namely between the concentration of paper mill effluent and the dose of guano fertilizer, each treatment was repeated three times. The microbial population can be determined by analyzing total bacteria, total fungi. Soil that had been contaminated with paper mill waste was incubated with guano fertilizer, each combination was analyzed at 15 hst and 30 hst for total bacterial and total fungal populations. During the incubation period, irrigation was carried out using a sprayer to maintain moisture in the incubation media. The results showed that the total population of bacteria and fungi in the growing media contaminated with paper mill sludge waste by administering different doses of guano showed results that were not significantly different, but the total population tended to increase. with increasing incubation period. Pollution of sludge waste in the planting medium has a significant effect on increasing the total Fungi Population when compared to the control. The relationship between paper mill effluent pollution and guano fertilization is very low with a coefficient of determination of less than 0.5.

Healthy Food After COVID-19 Vaccination

Coronavirus is a cause of infectious diseases. The European Food Safety Association (EFSA), on March 9, 2020, explained that there is no evidence yet to show that food is part of the coronavirus transmission route (of course, when we consume food in the right and clean way standard). Basic Health Research conducted by the Ministry of Health in 2018 shows that few Indonesian citizens are malnourished or suffer from diabetes. This group risks experiencing fatal health problems when attacked by the coronavirus. The aim of this health promotion is that the post-vaccination participants for COVID-19 in the D3 Nursing Study Program, Faculty of Nursing, University of Jember, Lumajang Campus, have a better understanding of consuming healthy food after the COVID-19 vaccination. The service method uses counseling using lectures, question and answer, and demonstrations with X banner and leaflet media for participants after the COVID-19 vaccination, which was carried out on March 17, 2022, taking place at the D3 Nursing Study Program, Faculty of Nursing, Universitas Jember, Lumajang Campus. The results of this community service activity are likely successful. This can be observed in the level of attendance and the activeness of the participants. This activity took place in an orderly and good manner without experiencing significant obstacles. The follow-up that needs to be done is to continue to provide information on healthy food after the COVID-19 vaccination, so that confusing and untrue news can be suppressed so that the people of Indonesia are free of COVID-19, especially the people of Lumajang.

The Role Macrosystems as Main Proponent of the Ecology Approach in Scientific Writing Learning

The ecological approach is very appropriate for understanding mental, psychosocial, and linguistic development. The aims of this study is to describe the perceptions of sociocultural ecology in agro-industrial societies and their impact on scientific writing competence. Data were obtained by observation and questionnaires on 90 students at the University of Jember as student representatives with an agro-industry environment and their involvement in research and learning texts about agro-industry in the field of writing. The results show that there are groups with high sociocultural ecological perception and knowledge values and groups with low perception and knowledge values. To see the urgency of perception and knowledge of scientific writing competence, these students took a writing test and then the results were examined in terms of reasoning, text organization skills, and procedural knowledge. After the statistical tests were carried out, it was concluded that the perception and knowledge of the agro-industry macrosystem had a significant effect on students' reasoning abilities, significance (sig) 0.032 <0.05; does not have a significant effect on text organization competence with a significance value (sig) 0.067 > 0.05; and has a significant effect on procedural knowledge with a significance value (sig) 0.032 <0.05. These results indicate that the scientific productive competence of language with an ecological approach from the macrosystem aspect needs to pay attention to creativity. Greater efforts are needed to improve the development of writing on the components of unity, continuity, completeness, sequence, and point of view consistency.

Effect of flour-based feed of Tenebrio molitor l. on fresh water lobster (Cherax quadricarinatus von Martens) seed growth

Feed according to nutrient requirements is a major aspect to support optimum growth of C. quadricarinatus. Commontly, farmers still use fish flour as a source of feed nutrients. However, the price of fish flour often fluctuates. While, T. molitor L. flour has potential to be an alternative feed ingredient for C. quadricarinatus because of its high nutrient content. This study aims to determine the effect of feed based on T. molitor L. flour on C. quadricarinatus growth, which is measured by parameters of wet biomass (gram/week), dry biomass (gram/week), carapace length (mm/week), FCR, and FUE (%/week) during the research period. The research was carried out in March-September 2021 at the Animal Laboratory of the Biology Education Study Program, University of Jember.

This study was an experimental design using a completely randomized design, consisting of 2 treatments 1 control with 3 replications each. The results showed that feeding with flour-based T. molitor L. had a significant effect on the growth of wet biomass (p=0.047), dry biomass (p=0.046), and carapace length (p=0.011). However, FCR and FUE showed no significant effect (p=0.089; p=0.162 respectively).

The Increase of National Sugar Production as a Form of Achieving the 2nd SDGs through Mutation Breeding

Bululawang has been cultivated under increasing environmental pressures every year. Environmental pressures are accepted as one of the impacts of global climate change. This condition will cause a decrease in genetic ability, which can impact decreasing yields. The achievement of point 2.4 SDGs, especially in sugarcane, can be achieved through a sugarcane plant breeding program to improve and increase the genetic quality of several sugarcane varieties often cultivated in Indonesia. Mutation breeding to create high-yielding sugarcane varieties has been carried out by the Plant Breeding Laboratory of the University of Jember to increase national sugar production. Mutation breeding to produce superior sugarcane varieties has been carried out by the Plant Breeding Laboratory of the University of Jember to increase national sugar production. This study aims to obtain new high-yield varieties using the Bululawang variety as the parent. Mutation breeding using EMS mutagen resulted in three selected genotypes (M1, M2, and M3), further developed and tested for multilocation. The selected locations are Sukorambi-Jember District, Arjasa-Jember District, and Pakem-Bondowoso District. This study focuses on the agronomic characteristics and yield components of three mutant sugarcane compared to the Buluawang variety as the parent. Bululawang, M1, and M3 genotypes had high yield stability in all test sites. On the other hand, the M2 genotype was declared a specific-location genotype based on the Finlay and Wilkinson, Eberhart and Russell, and AMMI parametric stability tests.

Worldwide Efficiency of Bioremediation Techniques for Organic Pollutants in Soil: A Brief Review

Soil pollution is a major human and environmental issue. Among the several components of soil degradation, organic contaminant in soil is regarded as a significant factor that causes considerable damage to the environment along with several health dangers to humans. Polychlorinated biphenyls, polycyclic aromatic hydrocarbons, polychlorinated dibenzofurans, poly-brominated biphenyls, organic fuels particularly gasoline and diesel, herbicides, insecticides (carbamate and organophosphorus) are by far the most common forms of organic pollutants identified in soils. The employment of living organisms such as microorganisms and plants in bioremediation technology reduces/degrades, eliminates, and transforms pollutants found in soils, sediments, and water. This review examine and critically view the efficiency of bioremediation techniques for the polluted sites. The most common bioremediation technologies for the treatment of organic pollutants are bioventing, bio-sparging, bio-slurping, bio-augmentation, phytoremediation, bio-immobilization, bio-sorption, composting, land farming, aerobic degradation, co-metabolic and natural attenuation. The efficiency of these techniques depends on the pH, type of soil, level of oxygen, any other electron acceptors, temperature, and the nutrients. Selection of the treatment process depends upon the type of pollutant, concentration of the contaminant, site and source of pollution. All the treatment techniques are not good for all type of pollutants. Cost-effective techniques are mostly used worldwide as they have more public acceptance. Pump and treat methods were mostly used in Past but due to its non-reliability and excessive cost, these techniques are no longer in use.

Analysis of the Dynamics of Water Flow and Suspension Flow Discharge in Volcano Watershed with Settlement Land Use

Suspension flow into the upstream of volcano watershed is sensitive to land use. In Indonesia, a settlement is a form of land use in several volcanic landscapes. There is currently no detailed study on the suspension flow sediment from the settlement land use. The purpose of this study is to investigate the characteristics of the relationship between water and suspension flow discharge. The study was conducted through the measurements at a gully outlet that produced 747 suspension load data. For each rainfall event, suspension load measurements were made in the field, followed by laboratory analysis. Additionally, field surveys were used to determine the characteristics of settlement land use and the water flow into the gully system. According to the findings, the peak flow discharge corresponds to the peak suspension discharge, the peak flow discharge comes before the peak suspension discharge, and the peak flow discharge happens after the peak suspension discharge. The average time lag between initial rainfall events and suspension flow was 10.36 minutes, and the suspension peak content varied by an average of 2.22 gl-1. The grain size was also dominated by the clay fraction, averaging 67.86% on the ascending branch and 67.82% on the descending branch.

Analysis of Sea Surface Dynamics during the Coastal Floods in Manado

Coastal flooding is one of the serious problems facing most coastal areas in the world. On January 17 and December 7, 2021, coastal flooding hit the coastal area of Manado, North Sulawesi, Indonesia. The disaster disrupted economic activities on the coast of Manado Bay. This study analyzed the dynamics of the atmosphere and the sea during coastal flood events using water level data from the Geospatial Information Agency, which was then filtered to separate residual and atmospheric tide, and oceanographic reanalysis data of Wavewatch-III from BMKG Ocean Forecast System (OFS). The results show that events on January 17 and December 7, 2021, coincided with the occurrence of the maximum tide. The residual water level shows a significant value of around 0.2 – 0.3 m, indicating the influence of atmospheric phenomena on sea level rise. According to oceanographical data, the local wind is the main factor of flood occurrence, which is shown by wind speed data which increased wave height significantly to 1,5 m on January 17, 2021, and to 2,0 m on December 7, 2021, around Manado Bay coast. Another factor that might contribute to the event is Manado's land morphology. Further study must be conducted to discover the influence of land morphology on coastal floods.

Species Distribution Modelling Using Bioclimatic Variables on Endangered Endemic Species (Bubalus depressicornis and Bubalus quarlesi)

Sulawesi Island is an island located in the Wallacea area. Most of the fauna on the island of Sulawesi is a transitional fauna from Australia and Asia. This study aims to model the potential distribution of the species Bubalus depressicornis and Bubalus quarlesi using famous models in the present and in the future as a result of climate change phenomena throughout the island of Sulawesi and beyond their natural habitat. The parameters used are bioclimatic variables and in-situ presence data. The method used is Maximum Entropy by comparing the GLM, SVM, and RF algorithms. The model is evaluated with reference to the values of AUC, COR, TSS, Deviance, and observation data. The RF model is quite good in modeling the distribution of B. depressicornis and B. quarlesi species with AUC values of 0.92 and 1, COR values of 0.59 and 0.84, TSS values of 0.87 and 1, and Deviance values of 0.37 and 0.08, respectively, while the results of data observations show values of 80% and 84%. B. depressicornis was most affected by bio14=0.665, while B. quarlesi was most affected by bio2=0.525, which means that this endemic species is suitable to live in a tropical climate with a warm and wet climate throughout the year, where the difference in temperature at night and during the day is very large. In the future, B. depressicornis and B. quarlesi are estimated to be compatible in an area of 143,281.78 km2 (81%) and 136,892.89 km2 (77%) of the Sulawesi.

Emergency Response Demand and Supply: A GIS-Based Network Analysis for Fire Station’s Service Coverage Delineation in Kano Metropolis, Nigeria

Inadequate fire emergency response infrastructure and a lack of defined service coverage remain key barriers to timely fire disaster response. This study is applied research which employed geospatial techniques and aimed at examining fire disaster emergency response demand and supply relationships with the view to delineating service coverage and locating more facilities for optimum coverage in Kano metropolis. Locations of the existing fire stations and fire incidents (2009-2019) were gathered through GPS surveying. Network data set were generated. Nearest Neighbor and Network Analysis (origin-destination, service coverage and location-allocation) were conducted to determine emergency response demand and supply relationships, service coverage area delineation and identifying best site for allocating new facilities within the metropolis respectively. It was found that no clearly defined service coverage exist as emergency response supply takes more than 4-8 times the NFPA travel standard, and with a great deal of overlapping response patterns. New service coverage areas were proposed and best sites for 8 firefighting facilities identified for optimum coverage. It is concluded that emergency fire disaster response demand and supply relationships within Kano metropolis is imbalanced, with extensive recurrent demand especially within the core area served by overstretched and inefficient response supply. This, therefore, implies continuous exposure of lives and properties to the menace of fire disaster in Kano metropolis.
