The Intimacy with Muzakki in Increasing Trust, Commitment and Loyalty to Increase ZISWAF Fund at Zakah Institutions
Authors: Soleh Mochammad , Linggasari Yasinta Suci 
Published: December 2023

Abstract
This study aims to determine the effect of the intimacy of zakat institutions with muzakki in order to gain trust, commitment and loyalty in order to encourage an increase in charitable funds, namely Zakat, Infaq and Sadaqah (ZIS). This study uses a quantitative approach through the Partial Least Square (PLS) method on 132 muzakki permanent members of zakat institutions using the variables of familiarity, trust, commitment, and loyalty. The results of this study note that the closeness of the relational relationship between zakat institution officials and muzakki as assessed from the familiarity factor in general has a positive relationship with the emergence of trust and commitment which in turn fosters muzakki's loyalty to the zakat institution they choose; However, this closeness does not significantly influence the emergence of trust, commitment and loyalty. One of the reasons for this to happen is that the public still has high distrust of zakat institutions, so it is very important for zakat institutions to start using a professional and responsible management pattern and have the support of all people.

Abstrak
Penelitian ini bertujuan untuk mengetahui pengaruh keakraban lembaga zakat dengan muzakki guna mendapatkan kepercayaan, komitmen dan loyalitas agar mendorong peningkatan dana amal yaitu Zakat, Infaq dan Shadaqah (ZIS). Penelitian ini menggunakan pendekatan kuantitatif melalui metode Partial Least Square (PLS) pada 132 muzakki anggota tetap lembaga zakat dengan menggunakan variable keakraban , kepercayaan, komitmen, dan loyalitas. Hasil penelitian ini diketahui bahwa keeratan hubungan relasional antara petugas lembaga zakat dan muzakki yang dinilai dari faktor keakraban secara umum memiliki hubungan yang positif dengan timbulnya kepercayaan dan komitmen yang pada akhirnya menumbuhkan loyalitas muzakki pada lembaga zakat yang mereka pilih; akan tetapi keeratan tersebut tidak berpengaruh secara signifikan terhadap munculnya kepercayaan, komitmen dan loyalitas. Salah satu sebab hal tersebut terjadi adalah masih tingginya ketidakpercayaan masyarakat terhadap lembaga zakat sehingga sangat penting bagi lembaga zakat untuk mulai menggunakan pola manajemen yang profesional dan bertanggung jawab serta mendapat dukungan dari semua umat.

Published: December 2023

Background: Composite resin is the most used material for caries restoration and highly chosen by dental patients regarding it’s high aesthetic value. People often use mouthwash to maintain dental and oral hygiene, both those containing alcohol and non-alcohol. According to several studies, the alcohol in mouthwash will cause a decrease in the physical properties of the composite resin, such as surface roughness, compressive strength, hardness, and also the aesthetic value of the composite resin. Objective: To determine the difference of bioactive composite resin color on immersion in alcohol and non alcohol mouthwash. Methods: Experimental laboratory with a pre-test and post-test with control group design using 27 samples of composite resin with a diameter of 15 mm and 1 mm. The samples were divided into 3 groups, namely the immersion group in alcoholic mouthwash, non-alcohol, and aquades. Each group consisted of 9 samples to be measured the value of color change before and after immersion for 12 hours. Results: The results of the One Way ANOVA statistical test showed that there was an effect of soaking mouthwash on the color of the bioactive composite resin. The Post Hoc LSD test showed between the alcohol and non-alcohol mouthwash group, as well as alcohol and distilled water group had a significant difference, but not in the non-alcohol mouthwash and distilled water group. Conclusion: The immersion in both alcohol and non- alcohol mouthwash are significantly affecting the color changing in bioactive composite resin. The value of color changing between mouthwash goups are significantly different. Keywords: Bioactive composite resin, discoloration, liquid absorption, mouthwash.

Published: December 2023

Background: Periodontal disease is the second most frequent oral disease in Indonesia, which includes periodontitis. Porphyromonas gingivalis is the predominant bacteria in chronic periodontitis. This disease is usually treated with 0.2% chlorhexidine gluconate mouthwash. However, 0.2% chlorhexidine gluconate has several adverse effects, such as tooth discoloration, irritation of the oral mucosa, and changes in taste sensation. Therefore, an herbal-based mouthwash is needed. A combination of kelakai leaf and katuk leaf extract contains antibacterial substances such as flavonoid, tannin, steroid, alkaloid, and saponin, which can be used as an alternative therapy for chronic periodontitis. Purpose: To compare the inhibitory zone of kelakai and katuk extract combination with 0.2 Chlorhexidine gluconate against Porphyromonas gingivalis. Method: True experimental design with 13 treatment groups and 3 repetitions for each group. The treatment groups include combinations of kelakai leaf extract with 25%, 50%, 75%, 100% concentrations and katuk leaf extract with 20%, 40%, 80% concentrations and 0.2% chlorhexidine gluconate, which were tested on Porphyromonas gingivalis with a total of 39 samples. The inhibitory zone is measured with caliper after incubated for 48 hours. Results: One-Way ANOVA revealed significant differences between all treatment groups and 0.2% chlorhexidine gluconate. Consequently, the Bonferroni post-hoc test was performed, which showed that the antibacterial activity of 75% kelakai leaf and 80% katuk leaf extract did not differ significantly from the activity of 0.2% chlorhexidine gluconate. Conclusion: The combination of 75% kelakai leaf and 80% katuk leaf extract has an equal antibacterial activity to 0.2% chlorhexidine gluconate against Porphyromonas gingivalis statistically. Keywords : 0.2 % Chlorhexidine gluconate, chronic periodontitis, combination of kelakai and katuk leaf extract, inhibitory activity, Porphyromonas gingivalis
DESENVOLVIMENTO MOTOR E COGNITIVO NOS ANOS INICIAIS: UM ESTUDO TRANSVERSAL
Authors: ALBERT ÉVELIN 
Published: December 2023

Este artigo é fruto de uma pesquisa feita com crianças entre 9 e 11 anos de uma escola pública do município de Porto Alegre, Rio Grande do Sul, e teve por objetivo investigar o desenvolvimento motor e escolar delas. Sabendo-se que dos 9 aos 11 anos a criança já deveria ter atingido o estágio maduro e especializado do movimento, os resultados desta pesquisa apresentaram que elas encontravam-se em estágios abaixo do esperado para a sua faixa etária. O mesmo ocorreu quando elas foram testadas quanto ao seu desempenho escolar. Em crianças que possuíam Transtorno do Déficit de Atenção com Hiperatividade (TDAH​), os índices de desenvolvimento motor mostraram-se ainda menores. Desta forma, pode-se concluir que possivelmente pela falta de oportunidades para a prática, encorajamento e instrução em um ambiente que promova o aprendizado dos movimentos, as crianças pesquisadas encontram-se nos estágios motores e escolares apresentados.

Triphenylphosphonium (TPP) derivatives of a decapeptide related to sequences of bactenecin 7 (Bac7) and oncocin (Onc112) were synthesized and studied as potential antimicrobial compounds using various biochemical and microbiological assays. It was shown that while the reduction of the Bac7 length to 10 a.a. residues dramatically decreases the affinity to bacterial ribosomes, the modification of peptide with alkyl-TPP moieties leads to an increase in the affinity. New analogs which structure combines a decapeptide related to Bac7 and Onc112 — Bac(1-10, R/Y) — and TPP, attached to the C-terminal amino acid residue through alkylamide linkers, inhibit translation in vitro and are found to be more selective inhibitors of bacterial translation as compared with eukaryotic translation, than Onc112 and Bac7. Triphenylphosphonium analogs of a decapeptide related to Bac7 and Onc112 suppress the growth of both gram-negative bacteria, similar to Onc112 and Bac7, and gram-positive ones as alkyl-TPP derivatives, and also act against some resistant laboratory strains. Bac(1-10, R/Y)-C2-TPP, containing a short alkylamide linker between the decapeptide and TPP, is transferred into the E. coli cells via the SbmA transporter protein. TPP derivatives of the decapeptide Bac(1-10, R/Y) containing either decylamide or ethylamide linker cause B. subtilis membrane depolarization, similar to alkyl-TPP. The Bac(1-10, R/Y)-C2-TPP analog is proved to be non-toxic for mammalian cells by MTT-test.

The dynamic process of plants’ growth is primarily influenced by interconnected biochemical and physiological activities that operate throughout different growing phases. These processes respond to environmental conditions, affecting plant development and productivity. The present studies were carried out to investigate greenhouse conditions&#039; impact on winter-grown cherry tomatoes (Cheramy F1) in terms of growth, yield, and nutritional composition.Data was collected on various dates during the period extending from December 2022 to March 2023. The greenhouse temperature varies from 22°C to 25.47°C (avg. 21.20°C) during plant growth and from 20°C to 23.85°C during fruit-bearing. Average CO2 concentration was 349.19 ppm; average light was 240.93 w/m2. Measured growth parameters include plant height, leaf growth, stem diameter, leaf spacing, leaf count, leaf area, and inflorescence count per plant. The key results of this study revealed the progressive growth report (PGR), which predicted the daily potential growth rate of plants: plant height, 2.86 to 3.81 cm/day; growth rate of mature old leaf: 0.003988 m2/day; middle younger leaf: 0.008733 m2/day; top Nascent leaf: 0.010722 m2/day; three to five leaves per week; and one inflorescence per week. In our accidental observation, we observed that plants with different orientations and growing spots within the greenhouse responded differently in view of their growth parameters. A exceedingly significant interaction among the inflorescence was found in view of length of inflorescence, number of fruits inflorescence, total fruit mass inflorescence, average fruit mass inflorescence, fruit dry matter inflorescence, fruit height inflorescence, and fruit diameter inflorescence. A non-significant interaction was found between the fruit keeping quality (Shelf days), fruit size, and inflorescence number. Inflorescence with a high, lower leaf area appeared to have high productivity. The nutritional composition of fruit was also different among the inflorescences.. The study&#039;s goal is to investigate and gather data to test the hypothesis that changes in greenhouse conditions and the adoption of green management practices will directly influence plant growth attributes, productivity, and fruit quality. The findings of this research could be valuable for optimizing greenhouse operations to enhance crop yields and quality while also promoting environmental sustainability.
Energy Efficiency of Using Hybrid Heating Points in Conditions of Integration of Electrical and Thermal Networks of Urban Neighborhoods. Part 1. Justification of the Feasibility of Using Hybrid Thermal Points
Authors: Sednin A. V. , Pozdnyakova M. I. 
Published: December 2023

The paper discusses the circumstances and technical solutions that contribute to the integration of electrical and thermal networks of urban neighborhoods within the framework of a surplus of electricity generating capacities arising from the imbalance in the development of energy generation and consumption, stochastic processes of market economy development, the transfer of energy-intensive industrial production to other countries, the desire to diversify fuel energy resources, passion for the construction of energy sources for alternative energy resources in counterbalance to traditional energy facilities without taking into account all aspects of the interaction of the former with the environment, etc. With regard to district heating systems of electrical and thermal networks of urban neighborhoods, the use of hybrid heating points is achieved, which, unlike standard solutions, are equipped with electric boilers, thermal accumulators and heat pumps. According to the time of use of generating capacities, preference should be given to options for covering the hot-water load. Based on the average daily load, the power usage time in this case lies in the range of 6000–6500 hours / year. When choosing the capacity of the equipment, it should be borne in mind that the daily load of hot water supply is extremely uneven and also depends on the day of the week, while the maximum load exceeds the average daily by 2.5 – 3.0 times. When integrating electricity and heat supply systems, it is advisable to consider options for only night-time electricity consumption or night-time consumption plus consumption during the hours of daytime failures of the electricity consumption schedule. If during the new construction the power of the electrical network may vary depending on the selected option, then during the modernization of the heat supply system, the problem is solved if there is a limitation on the available electrical power. Therefore, the definition of these restrictions is a separate issue. In comparison with the direct consumption of electricity for the needs of heat supply, which is a priori energetically and economically inefficient, the use of hybrid systems in heat supply allows us to solve the multifunctional task of increasing the reliability of energy supply and the stability of the functioning of the power system, which is primarily achieved by solving the problem of balancing the capacity of production and energy consumption from the position of aligning schedules of energy generation and consumption.
Analysis of carbon balance in Jiangsu, Zhejiang and Anhui provinces based on land use dynamics

Published: December 2023

Abstract

With global warming, the continuous increase of carbon emissions has undoubtedly become a difficult problem faced by mankind, and studying regional carbon balance is essential to promote the benign development of socio-economic and natural ecosystems and achieve the goal of "dual carbon". Taking Jiangsu, Zhejiang and Anhui provinces as examples, this study collects remote sensing images of land use types in the three provinces from 2010 to 2020, and analyzes the temporal and spatial dynamics of land use in the study area over the past ten years. On this basis, the net carbon emissions of the three provinces were calculated using the carbon emissions and carbon sink functions of land use to measure the carbon balance of the study area. The actual study found that the study area has been in a state of "carbon deficit", and the net carbon emissions have shown a continuous growth trend. Carbon emissions from land use are on the rise year by year, but the growth rate has slowed down. Based on the above results and analysis, this study puts forward policy suggestions for optimizing land use structure, changing land use mode and strengthening macro-control, in order to provide case reference and theoretical basis for regional carbon emission management.

Abstract

In this study, we examined major sources of particulate organic matter (POM) in Godavari River during high flow and low flow periods, to understand the impact of excess N-fertilizers used in agricultural fields. δ13CPOC and δ15NPN, elemental C:N and POC:Chl-a ratios indicated that in-situ sources predominantly contributed (~ 60%) during low flow period, whereas, terrestrial sources largely contributed during high flow period (75–80%). This is attributed to prevailing conducive conditions for phytoplankton growth during former, and increased transport of particulate and dissolved materials from land during latter period. δ15NPN during low flow (7.4 ± 2.9‰) and high flow (9.4 ± 2.1‰) periods demonstrate that contribution of POM produced from N-fertilizers (δ15NPN: 0 ± 1‰) is not significant, rather than hitherto hypothesized. It could be due to seepage of excess N-fertilizers used in agricultural fields into groundwaters rather than transporting to rivers and/or transformation to another from through nitrification/denitrification processes within soils.

Published: December 2023

Abstract

Aluminum alloy and copper used in lithium-ion batteries have low absorption and high reflectivity, so it is difficult to obtain stable joint strength when laser welding is applied. In order to overcome problems, this study has applied multi-seam weld to increase joint area of welded joints. An AA1050-H18 and C11020P sheets with a thickness of 0.5 mm were welded by 2 kW fiber laser welding. Effect of the welding parameters of pitch (0, 1, 4, 8 mm) on weldability in welded joints has been investigated. As the pitch of multi-seam increased, the tensile-shear load tended to increase. The maximum tensile-shear load in the multi-seam weld of pitch 8 mm was 1.25 kN, which was about 108% compared to the single-weld seam 0.6 kN. In addition, the minimum electrical resistance was 77 μΩ at the pitch of 8 mm, which decreased by approximately 49% compared to 115 μΩ of single seam welding. It is thought because resistance reduction caused by be changed from serial to parallel in multi-seam welding.

Abstract

In the aftermath of the World Trade Center (WTC) attack, rescue and recovery workers faced hazardous conditions and toxic agents. Prior research linked these exposures to adverse health effects, but mainly examined individual factors, overlooking complex mixture effects. This study applies an exposomic approach encompassing the totality of responders' experience, defined as the WTC exposome. We analyzed data from 34,096 members of the WTC Health Program General Responder, including mental and physical health, occupational history, traumatic and environmental exposures using generalized weighted quantile sum regression. We find a significant association between the exposure mixture index all investigated health outcomes. Factors identified as risk factors include working in an enclosed heavily contaminated area, construction occupation, and exposure to blood and body fluids. Conversely, full-time employment emerged as a protective factor. This exposomics study emphasizes the importance of considering combined exposures. In an era marked by more frequent and severe natural disasters due to the evolving climate crisis, the exposomic framework holds promise as a valuable tool for disaster preparedness.
