Authors:   Lomonosov Moscow State University, Lapidus Larisa V. , Gostilovich Alexander O. ,   Lomonosov Moscow State University
Published: October 2023

Introduction: the popularity of sharing mobility services explains their ability to resolve the “first-mile-last-mile” problems in a seamless transport system. The operation of these services is based on digital technologies, and this places high demands on the quality of such services due to the presence of traditional alternatives in the field of transportation. Ridesharing is a vivid example of such digital sharing services, tempting the companies interested in resolving transport problems to enter this market. Objectives: to explore the attitudes of ride-sharing services users to the quality of services by assessing the levels of loyalty and consumer satisfaction, as well as to develop proposals for improving the quality of relevant services. Methods: systematic approach, analysis and synthesis, expert assessments, sociological research. The study involved 290 respondents from Moscow and the Moscow region who use ridesharing at least once a year. To measure user loyalty to ridesharing services, the consumer loyalty index (Net Promoter Score, NPS) proposed by Frederick Reicheld was used. To assess user satisfaction, the Consumer Satisfaction Index (CSI) was used. Results: it has been revealed that the NPS is negative and amounted to –27.24 %; however, the CSI is estimated at 72.74 %. Loyalty drivers appear to be: (1) convenience, (2) price, (3) safety. The users’ greater satisfaction is the technical condition of cars, safety during the trip and its price. The users are less satisfied with the comfort during the trip, the time of trip registration, the time to register in the application. Conclusions: despite the negative level of loyalty, ridesharing is a promising direction for the development of mobility services, since the quality determinants that affect the loyalty level can be improved by raising the quality of sharing services and the possibility of influencing the processes for which low satisfaction has been identified.
Does adding muscle relaxant make post-operative pain better? a narrative review of the literature from US and European studies
Authors: Verdiner Ricardo , Khurmi Narjeet , Choukalas Christopher , Erickson Colby , Poterack Karl
Published: October 2023

Centrally acting skeletal muscle relaxants (CASMR) are widely prescribed as adjuncts for acute and chronic pain. Given the recent interest in multimodal analgesia and reducing opioid consumption, there has been an increase in its use for perioperative/postoperative pain control. The mechanism of action, pharmacodynamics, and pharmacokinetics of these drugs vary. Their use has been studied in a wide range of operative and non-operative settings. The best evidence for the efficacy of CASMRs is in acute, nonoperative musculoskeletal pain and, in the operative setting, in patients undergoing total knee arthroplasty and abdominal surgery, including inguinal herniorrhaphy and hemorrhoidectomy. The risk of complications and side effects, coupled with the limited evidence of efficacy, should prompt careful consideration of individual patient circumstances when prescribing CASMRs as part of perioperative pain management strategies.
Do tourism promotional videos on social media elicit pleasure-related emotions from viewers?: An experimental approach
Authors:   The Tourism Sciences Society Of Korea, Kim Sohye , Lee Hoon
Published: October 2023

This empirical study aims to investigate the impact of viewing tourism promotional videos on social media channels on viewers’ emotional responses. A combination of cognitive- and physio-psychological measures (i.e., SAM and HRV) was applied to assess participants' basic emotional responses (i.e., pleasure and arousal). Participants consisted of 72 Korean undergraduate students, divided into three groups. The control group watched the baseline video (Control), while two experimental groups viewed videos featuring ether dynamic (Group 1) or static tourism activities (Group 2). Results showed that the average arousal level of Group 1 was higher than that of Group 2, while no statistically significant difference was observed in the degree of pleasure between the two groups. Additionally, LF, HF, SDNN, and RMSSD increased as participants watched tourism promotional videos, regardless of their content. These results, which highlight consistent and heightened pleasure-related responses despite variations in arousal, provide intriguing insights into the role of pleasure in tourism promotions. Pleasure may serve as an emotional common ground, fostering effective and mutually satisfactory communication between viewers and producers in the realm of social media and online tourism promotion. This study contributes to a deeper understanding of the emotion-based tourism phenomenon and offers valuable implications for the development of social media and online marketing strategies.

This study offers a comprehensive evaluation of the efficacy, benefits, and limitations of fiber-reinforced composites (FRCs) in fixed prosthodontics. Emerging as a substitute for conventional dental materials such as metals and ceramics, FRCs are now used in a variety of applications, from dental crowns and bridges to veneers. The study is based on an exhaustive literature review and explores various properties of FRCs, such as mechanical, optical, viscoelastic, adhesive, and thermal attributes. The strength and rigidity of constructions made from FRC are dependent on the polymer matrix of the FRC and the type of fiber reinforcement. In dental appliances of relatively small sizes, the quality of the load bearing FRC sub-structure is very important. A special emphasis is placed on the clinical applications and future potential of these materials. The advantages of using FRCs include their biocompatibility, light weight, durability, and aesthetic superiority. However, there are limitations, such as higher costs and concerns about long-term clinical performance, specifically related to interface degradation. The study concludes that FRCs hold significant promise in the domain of fixed prosthodontics, although further research is needed for optimizing their long-term effectiveness.

Published: October 2023

Introduction: Restless legs syndrome (RLS) is a common sensorimotor sleep disorder, and rheumatoid arthritis (RA) is an inflammatory autoimmune disease that causes disability. Previous studies showed that the prevalence of RLS varies in different populations of RA (13.2 – 68.4%). It raises the need for a pooled metaanalysis to determine a more reliable estimate. Therefore, we aimed to perform a meta-analysis to assess the pooled prevalence of RLS in RA patients.
Methods: Meta-analysis was performed according to the PRISMA checklist. Embase, MEDLINE, Ovid, Web-of-Science, and Scopus databases were used for the systematic search, and eligible studies were analyzed using R version 4.0.3. For further review, we performed sensitivity analyzes to identify influential studies.
Results: Of a total of 763 studies, 11 studies (3 were from Europe, 4 from North America, and 4 from Asia) were suitable for synthesis. A total of 931 RA patients were identified, 300 of whom had symptoms of RLS. The pooled prevalence of RLS among people with RA from 11 studies was 34% (95% CI: 26-43%). The pooled prevalence of RLS in Europe, Asia, and North America was 48% (95% CI: 32-65%), 32% (95% CI: 18-45%), and 28% (95% CI: 15-42%), respectively. RLS prevalence was dramatically high in RA women patients (32% CI: 23-41%) than RA men patients (3%; 95% CI: 2-5%).
Conclusion: This systematic review and meta-analysis indicates that the risk of RLS in RA patients was 34% and female patients with RA were more prone to having RLS than male patients.
Beta-Geometric Regression for Modeling Count Data on First Antenatal Care Visit (ANC) with Application
Authors: Al-Balushi Zainab M. , Sarr Amadou , Islam M Mazharul
Published: October 2023

Introduction: Little attention has been paid to modeling count data with the geometric distribution. There are many real-life phenomena with a constant probability of first success. However, in practice, the probability of the first success may vary, making simple geometric models unsuitable for modeling such data. One can assume one of many continuous distributions for modeling the probability of first success with the parameter space [0, 1]. In this respect Beta distribution defined on the standard unit interval [0,1] is the most useful distribution due to its ability to accommodate a wide range of shapes. Thus, in this paper, by mixing Beta and geometric distribution, we developed a Beta-geometric distribution for modeling the count data through application to real-life count data on time to the first antenatal care (ANC) visit.
Methods: The estimation of the distribution parameters using the method of moments, maximum likelihood estimation (MLE) method, and Bayesian estimation approach are provided. Based on the Beta-geometric distribution, we developed a new Beta-geometric regression model for analyzing count data that follow the geometric distribution. The goodness of fit of the derived model has been tested using real data on time to the first ANC visit.
Results: Beta-geometric distribution has a simple form for its probability mass function (pmf), and is flexible in capturing both underdispersion and overdispersion that may present in count data. It was found that the proposed Beta-geometric regression model fit the count data on the first ANC visit better than simple geometric distribution or Negative Binomial distribution.
Conclusion: Unlike the Poisson or Negative Binomial distribution, Beta-geometric distribution does not need an additional parameter to accommodate underdispersion or overdispersion and thus could be a flexible choice for analyzing any count data. The goodness of fit test of the Beta-geometric model provides better fitting of the model to real data on time to first ANC visit than geometric or Negative binomial models.

Authors: Razen Elvina Roseva , Sulistiyaningsih Retno
Published: October 2023

The COVID-19 pandemic has had a wide impact on the psychological condition and well-being of employees. This is pertinent, especially to Generation Z employees, as the second largest generation in Jakarta. Conditions during the pandemic resulted in a host of problems for Generation Z employees, which will lead to a fall in their job performance. In the”happy worker hypothesis”, job performance is directly influenced by job satisfaction. Therefore, this study aimed to explore the influence of job satisfaction on the job performance of Generation Z employees after the COVID-19 pandemic. The study used a causal associative model. The sampling technique used was purposive sampling with several criteria that needed to be fulfilled, which finally resulted in 389 respondents. This study used two psychological instruments: the Minnesota Satisfaction Questionnaire (MSQ) developed by Weiss et al. (1967) to measure job satisfaction and the Individual Work Performance Questionnaire (IWPQ) developed by Koopmans (2014) to measure job performance. The hypothesis test used was a simple linear analysis. The results discovered that job satisfaction affects job performance significantly and positively. This means that higher job satisfaction is followed by an increase in job performance in Generation Z employees after the COVID-19 pandemic (t = 0.684; p=0.000<0.05; R2=0.504). Job satisfaction had a 50.4% influence on job performance.

Authors: I'tisham Muhammad Rayhan , Chusniyah Tutut Chusniyah , Tania Basma
Published: October 2023

This study aimed to examine the self-acceptance of the victims of the Binomo fraudulent investment using a qualitative research method and a case study approach. Five research subjects experienced a loss of more than 3 million Rupiah due to playing Binomo and aged 18-25 years. They were selected by purposive sampling-snowball sampling. Data were collected through in-depth interviews and observation. Thematic analysis and source triangulation through interviews and observations were used to ensure valid findings. The results found that most subjects had good positive self-acceptance, but there were obstacles and discomfort in presenting themselves as they were victims of fraudulent investments. It has implications for the absence of external factors or support from the environment because victims feel ashamed and do not share their experiences with others, so the internal factor is the most supportive factor in the acceptance of the self in the victims of investment. Each individual has a different dynamic of self-acceptance sequence of stages, and it takes time for self-acceptance. However, all subjects in this study experienced at least two stages of self-acceptance and the bargaining stage were experienced before entering the acceptance stage. The length of the self-acceptance process was not always related to the magnitude of the loss. It is hoped that further research will deepen and enrich the findings with different subject characteristics and prove the interrelationship of the variables obtained in this study to become novelties for science in psychology.

Authors: Octamelia Vionisya , Sa'id Mochammad
Published: October 2023

This study aimed to determine how internalized misogyny influences rape myth acceptance among women. This investigation employed a quantitative correlational design. 396 college women between the ages of 18 and 25 who were studying at universities in Malang City were recruited using incidental sampling. This study employed two instruments to measure internalized misogyny and rape myth acceptance, Piggott’s Internalized Misogyny Scale (2004) and McMahon & Farmer’s Illinois Rape Myth Acceptance Scale (2011). A multiple linear regression test was used to test the hypothesis. The results of the data analysis demonstrated that internalized misogyny had a significant effect on women’s acceptance of the rape myth (F = 2209.310; p = 0.000 < 0.05; R2 = 0.944). The three dimensions of internalized misogyny, namely the devaluation of women (t = 47.731; p < 0.01), distrust of women (t = 51.762; p < 0.01), and gender bias in favor of men (t = 48.696; p < 0.01) partially influenced rape myth acceptance against women.

Published: October 2023

The phenomenon of online disinhibition prompts individuals to relax their internal boundaries, as they can deviate from social norms, particularly in virtual environments. Individuals tend to engage in behaviors that may cause disruption to others and pose potential harm to themselves. We assume that internet usage is expected to remain significant in the coming years, so a tool is needed to assess this phenomenon. We use The Confirmatory Factor Analysis tool to test adapted version of The Online Disinhibition Effect scale from English to Bahasa Indonesia. The analysis findings indicated that the tool is suitable for characterizing the online disinhibition effect X2 (6, 252)=.48, p=.49. It means that this instrument is suitable for use in Indonesia.

Analysis of the suitability of road mirrors for future telematics solutions
Authors: Masłowski Dariusz
Published: October 2023

A huge and quite important role in safe exit from the street with limited visibility plays traffic mirrors. Traffic mirrors, also known as safety mirrors or blind spot mirrors, have a significant impact on road safety. These mirrors are designed with a curved surface that allows for a wider field of view, making it easier for drivers to see objects and vehicles that may be in their blind spots. In order to commit a safe maneuver driver should be confident that the car moving down the street is at a sufficient and safe distance from the exit. Of course, the driver needs to have a perception of the time of the moving car to the place of exit from the street. All of these things play a significant role in safety exit and avoiding collisions. Traffic mirrors ensure an overview of the situation on the road. Moreover, the driver can measure the approximate distance by counting time for approaching the car. The experiment presented in the work is based on the time of the car’s approach. The purpose of this article is to detect the optimal time as well as distance before the street with limited visibility in order to exit the street safely and to avoid collisions. In this paper, we provide systematic approach to the research of a data and statistics of this data.
The role of the neural NO synthase adapter protein in the pathogenesis of metabolic syndrome and type 2 diabetes mellitus
Authors: Kuznetsova L. A. , Basova N. E.
Published: October 2023

The pathogenesis of metabolic syndrome (MS) is characterized by obesity, hypertension, dyslipidemia and insulin resistance. MS increases the risk of developing type 2 diabetes mellitus (DM2). The neuronal isoform of nitric oxide synthase (nNOS) is defined by complex protein-protein interactions, since nNOS, unlike other isoforms of NOS,contains a C-terminal PDZ domain, which allows it to conjugate with other proteins and, first of all, to interact with an adapter of neuronal, or type 1, nitric oxide synthase (NOS1AP), also denoted CAPON in our work. Changes in the interaction between nNOS and NOS1AP lead to metabolic disorders in brain, heart, liver and skeletal muscles, which plays a key role in the development of MS and T2DM. NOS1AP, interacting with the PDZ domain of nNOS, competes with the postsynaptic density protein (PSD95) and regulates the stability of subcellular localization of nNOS and enzyme expression during synapse formation. NOS1AP promotes nNOS binding to targets such as small GTPase (Dexras1), synapsines, regulating the formation of dendritic roots, mediates activation of the nNOS-p38MAP kinase pathway during excitotoxicity. It has been shown that single-nucleotide polymorphism of the NOS1AP gene and its overexpression in the myocardium leads to the manifestation of long QT syndrome, which is most clearly manifested in elderly patients with DM2. It was found that the genetic polymorphism of NOS1AP affects insulin secretion when using calcium blockers, and can promote the development of DM2. The functional role of NOS1AP in stabilizing the functions of skeletal muscle nNOS in the cytoskeletal complex associated with dystrophin/utrophin was discovered. The purpose of the review is to provide updated information on the role of NOS1AP and the nNOS/NOS1AP complex in the pathogenesis of MS and DM2. The potential molecular mechanisms of the interaction of NOS1AP with nNOS and with other proteins, which leads to change in nNOS activity, localization and content, are discussed.

The development of safe drugs occupies a special place in the pharmaceutical industry. One of the main tasks of its preclinical phase is to evaluate possible toxic effects of the developed drug on the body and on various systems, including the immune system. The aim of our work was to study immunotoxic properties of pegylated hyaluronidase (PEG- HYAL). Material and methods. Mice F1(CBA/C57Bl/6) were divided into subgroups which were intragastric and intraperitoneally administered with PEG-HYAL in different dosages (50, 500, 1250, 2500 and 5000 U/kg). The number of antibody-producing cells in the spleen, the mass and cellularity of central and peripheral immune organs, phagocytic activity of peritoneal macrophages and neutrophils, delayed hypersensitivity reaction (DHR), level of hemagglutinin to sheep erythrocytes, spontaneous and mitogen-induced splenocyte proliferation were determined. Results. PEG-HYAL did not induce DHR, did not suppress phagocyte activity of peritoneal macrophages, at a dose of 50 ED/kg did not significantly affect the hemagglutinin content to erythrocytes, but at a dose of 500 ED/kg did statistically significantly reduce the titer of specific antibodies. When experimental animals were exposed to PEG-HYAL at doses of 50 and 500 U/kg, spontaneous and mitogen-induced proliferation of splenocytes decreased. Conclusions. The PEG-HYAL trial produced results that can be used to substantiate the administration of the PEG-HYAL-based medication.

The purpose of the study is to associate alcohol consumption with the level of surfactant proteins SP-A and SP-D in Novosibirsk population. Material and methods. 174 people (87 men and 87 women) aged from 45 to 69 were examined. The study participants were randomly selected. Alcohol consumption was assessed using the AUDIT test. The content of surfactant proteins SP-A and SP-D in blood serum was determined by enzyme immunoassay using standard ELISA test sets. Statistical analysis was performed using parametric and nonparametric methods of descriptive statistics, correlation analysis was performed using Spearman criterion, and multivariate analysis was performed using binary logistic regression. ROC analysis was used to evaluate the diagnostic significance of the variables and to determine sensitivity and specificity. The critical level of significance for the null hypothesis (p) was accepted to be 0.05 in all statistical analysis procedures. Results. A typical single dose of alcohol consumed of 7–9 alcohol units (TSDAC) was inversely associated with SP-A content (r = –0.154, p = 0.043) in a general sample of men and women aged 45–59 years in Novosibirsk. By means of ROC analysis, SP-A was found to be a marker (area under the ROC curve equals 71.2 %) of alcohol intake in TSDAC. With a SP-A level not more than 921 pg/ml, its sensitivity to the determination of alcohol consumption in TSDAC is 68.7 %, the specificity is 87.5 %. Regression analysis showed that the variable “TSDAC” directly affects the presence of SP-A in a concentration not preceding 921 pg/ml (Exp (B) = 13.0; 95 % CI = 1.5; 111.0, p = 0.019) regardless of age and sex. In the general sample of men and women in Novosibirsk aged 45–69 years, as well as in men, inverse associations of Sp-D content with the presence of >0 points were found in the answer to the AUDIT test question “How often during the last year have you not done something that was expected of you?”. It was determined that women had a higher level of SP-A in the blood than men. Perhaps this is due to the fact that women smoked less often than men (10.3 and 23.0 %, respectively, p = 0.020). So, it was established that a high TSDAC is an independent factor directly influencing the presence of SP-A level in the blood not exceeding 921 pg/ml for men and women aged 45–69 years in Novosibirsk.

Following vegetarian diets means, to varying degrees, the exclusion of animal products from diets, which, if poorly planned, can lead to deficiency of some nutrients. Aim of the study was to evaluate some indicators of nutritional security of children with a restrictive type of nutrition and living in the territory of a long-term military conflict in the Donbass. Material and methods. 80 school-age children following restrictive diets were examined. All patients were divided into two groups: 40 children following a dairy-free diet (group 1), 40 children on a vegetarian type of diet (group 2). The control group consisted of 30 children who adhere to the traditional type of diet. Calcium, ferritin, vitamin B12 and zinc content in blood serum were studied in all children, living in Donbass. Results. In group 1 deficiency of calcium was found in 60.0 %, of zinc – in 32.5 %, of vitamin B12 – in 15.0 %, a decrease in ferritin content – in 22.5 %. In group 2 level of ferritin was declined in 55.0%, zinc deficiency was detected in 37.5 %, vitamin B12 deficiency – in 30.0 %, calcium deficiency – in 10.0 %. Conclusions. For children on a long-term dairy-free diet, calcium and zinc deficiency is characteristic, as well as a decrease in tissue iron reserves. Children who observe lactovegetarianism are characterized by a deficiency of zinc and vitamin B12, as well as a decrease in the concentration of ferritin in the blood serum. Children living in the Donbass in the conditions of a long military conflict and adhering to restrictive types of nutrition can be considered as a risk group for the development of deficient conditions. To correct the identified imbalance, it is necessary to develop programs for the supplementation of macro- and micronutrients.
Sektorowa dekompozycja wzrostu wydajności pracy w krajach Unii Europejskiej
Authors: Grodzicki Maciej
Published: October 2023

W artykule zostały zaprezentowane wyniki analiz wzrostu wydajności pracy w 14 krajach Unii Europejskiej w latach 1970–2007, wykonanych techniką dekompozycji sektorowej shift-share. Przy wykorzystaniu danych z baz EU-KLEMS i GGDC Productivity Database zbadano rolę zmian wydajności pracy w 5 sektorach gospodarki oraz przesunięć w zatrudnieniu pomiędzy tymi sektorami dla dynamiki wydajności na całym obszarze gospodarczym. Następnie przy wykorzystaniu metody nieparametrycznej (ważonej regresji lokalnej) zostały wyszczególnione dominujące wzorce rozwojowe. Okazuje się, że średnio blisko 90% wzrostu wydajności pracy w badanej próbie można przypisać wewnątrzsektorowej dynamice wydajności, a ok. 11% zmianom w strukturze zatrudnienia. Przesunięcia pracowników przebiegały zazwyczaj w kierunku sektorów o wyższej wydajności, lecz o niższej stopie wzrostu tej zmiennej. Największy wkład do wzrostu wydajności, na każdym poziomie rozwoju gospodarczego, mają sektory przemysłu i usług rynkowych. Dynamika wydajności jest najwyższa na niskim poziomie rozwoju, a wraz z jej wzrostem coraz trudniejsze staje się odnoszenie korzyści – zarówno wewnątrzsektorowych, jak i tych wynikających ze zmian w strukturze zatrudnienia.

Root caries is common in the elderly, usually detected late, involving enamel, cementum, and dentin below the cementoenamel junction (CEJ). Remineralisation is used to treat it when cavitation has not occurred. Bioactive glass triggers remineralisation by forming hydroxycarbonate apatite (HCA) at an early stage. Injectable paste preparations are needed to overcome these problems. The use of hyaluronic acid and carrageenan polymers supports the physical and mechanical properties of the paste preparation. The purpose this research to analyse the formation of HCA on the tooth root surface by administering bioactive glass (BAG) injection paste with the addition of seaweed carrageenan. This study was a laboratory experimental study with three research groups, namely treatment group 1 (BAG paste and hyaluronic acid), treatment 2 (BAG paste, hyaluronic acid and carrageenan), and control group (BAG without polymer). All groups were immersed in artificial saliva, incubated at 37oC for six days and then tested by Scanning Electron Microscope (SEM) to see the formation of HCA and FTIR. HCA was quantified by a scoring method according to predetermined score criteria. SEM showed HCA formation in both treatment groups, not the control group. There is HCA formation on the tooth surface by administering BAG injection paste with seaweed carrageenan.

Heat-cured acrylic resin is a material that is often used as a denture base. However, heat-cured acrylic resin is porous which can be a site for plaque accumulation. Streptococcus mutans is a microorganism that initiates plaque formation. Therefore, the cleanliness of the denture must always be maintained, one of which is by immersing the denture in 0.5% NaOCl solution. However, NaOCl can fade the color of acrylic resin and is corrosive. Alternative materials that can be used are materials derived from nature. Tamarind leaves are known to contain bioactive compounds that have antibacterial activity. The purpose of this study is to determine the potential of tamarind leaf extract at several concentrations that could inhibit the growth of S. mutans on heat-cured acrylic resin and the concentration that had the greatest ability to inhibit the growth of S. mutans on heat-cured acrylic resin. This type of research is a laboratory experimental study with a post-test-only control group design. Each acrylic resin plate will be contaminated with S. mutans for 24 hours and then immersed in the tamarind leaves extract concentration of 3.125%; 6.25%; 12.5%; 25%, positive control (NaOCl 0,5%), and negative control. The measurement of the number of S. mutans was carried out using a spectrophotometer. . The results showed that tamarind leaf extract was able to inhibit the growth of S. mutans on heat-cured acrylic resin and the highest concentrations in inhibiting the growth of S. mutans on heat-cured acrylic resin were 12.5% and 25%.

Land use change or land change can affect the ability of land to resist erosion. Vegetated land has a stronger erosion resistance than non-vegetated land. The level of criticality of an area's land can be seen from the amount of erosion. This study is purposely to identidy areas that have the potential for erosion based on their greenness index and also their slope. The method used is integration between NDVI (Normalized Difference Vegetation Index) and Slope by utilizing Landsat 8 satellite imagery recorded in 2014, Sentinel 2A satellite imagery recorded in 2018 and 2021, and Digital Elevation Model (DEM) data. Based on the analysis, it was found that the class levels of erosion potential were different in the three periods. The results showed that the Riam Kanan catchment area was dominated by very light erosion potential classes because the Riam Kanan catchment area was still dominated by green land. The potential for very light erosion occurs on predominantly green or vegetated lands such as secondary forests and rubber plantations. Meanwhile, the heavy erosion potential class occurs on land with minimal vegetation such as shrubs and mining landAlih fungsi lahan atau perubahan lahan dapat mempengaruhi kemampuan lahan dalam menahan erosi. Lahan yang bervegetasi memiliki kemampuan menahan erosi lebih kuat dari pada lahan tidak bervegetasi. Tingkat kekritisan lahan suatu daerah dapat dilihat dari besaran erosinya. Penelitian ini bertujuan untuk mengidentifikasi daerah yang berpotensi erosi berdasarkan indeks kehijauan dan juga kelerengannya. Metode yang digunakan adalah pengintegrasian antara NDVI (Normalized Difference Vegetation Index) dan Slope dengan memanfaatkan citra satelit Landsat 8 perekaman tahun 2014, citra satelit Sentinel 2A perekaman tahun 2018 dan 2021, serta data Digital Elevation Model (DEM).  Berdasarkan analisis didapatkan tingkatan kelas potensi erosi yang berbeda-beda dalam tiga periode. Hasil penelitian menunjukkan bahwa di DTA Riam Kanan didominasi oleh kelas potensi erosi sangat ringan dikarenakan DTA Riam Kanan masih didominasi oleh lahan yang hijau. Potensi erosi sangat ringan terjadi pada lahan dominan hijau atau bervegetasi seperti hutan sekunder dan perkebunan karet. Sedangkan kelas potensi erosi berat terjadi pada lahan minim vegetasi seperti semak belukar dan pertambangan

Research on provenance is one of the studies in the field of tree or forestry plant breeding which aims to determine the adaptability of one seed origin to the conditions in which it grows and the superiority of the provenance. Provenance test is important to determine the origin of quality forestry plant seeds, in this case the selected species is Kenari (Canarium amboinensis). In addition, the development of this species in the future uses seeds that come from quality seed sources. This study aims to determine the growth variations of two provenances of walnut (Canarium amboinensis) from Ambon and Seram islands. This research took place in April 2023 and was carried out at the Provenans Nursery of Kenari plants (Canarium amboinensis), which were 5 months old in Hatusua Village, Kairatu District, West Seram Regency. The results showed that of the 20 walnut seedlings in the provenance from Refinery Village, only 19 plants were alive and 1 plant was dead, so the percentage of survivors in walnut plants from Refinery Village was 95%. Meanwhile for Nikulukan Village, it was shown that of the 20 plants that should have existed, 17 plants were alive and 3 plants were dead, so the percentage of survival from the Kenari seedlings from provenance in Nikulukan Village was 85%. the results of the analysis above, t-count = -3.22 and when compared with t-table at α = 0.05 and degrees of freedom (db) = 35 is 2.03 then the absolute value of t-count is more than t-table so there is difference in the number of leaves of this plant in the two provenances

Estimating carbon stock in tropical rainforests is an important indicator of environmental health, and increasingly important in the era of climate change mitigation. In this study, we used Normalized Difference Vegetation Index (NDVI) classification on Sentinel-2 MSI imagery to estimate carbon reserves in the tropical rainforest of the Special Purpose Forest Area (KHDTK) of Lambung Mangkurat University. Sentinel 2 MSI satellite imagery was used to obtain information on NDVI values and land cover, while NDVI classification was used to connect this information with field data on carbon reserve calculations. The results of the study based on NDVI classification values in KHDTK varied between 0.0716 and 0.83424, consisting of five land cover classes: open land, shrubs, plantations or young secondary forests, intermediate secondary forests, and mature secondary forests. The carbon stock was obtained from 47% of the biomass calculated using existing allometric equations, with biomass measurements taken on trees with a diameter of 10 centimeters or more. The five land cover classes classified yielded a carbon stock of 6.05 tons/ha for open land, 13.40 tons/ha for shrubs, 21.04 tons/ha for young secondary forests, 39.56 tons/ha for intermediate secondary forests, and an estimated carbon reserve size of 49.44 tons/ha for mature secondary forestsEstimasi cadangan karbon pada hutan hujan tropis merupakan salah satu indikator penting dalam mengukur kesehatan ligkungan dan semakin penting dalam era mitigasi perubahan iklim.

This study aims to see the impact of the framing of the homecoming prohibition policy on public trust in the government considering that this topic is in accordance with the current situation (according to the context of the era). This study uses the Robert N. Entman model by paying attention to the Define Problems scheme, Diagnose Causes, Make Moral Judgment, and Treatment Recommendations. The results of this study indicate that the presentation of information through infographic media can provide a more interesting experience as well as can understand information easily because this infographic media contains the essence of the information itself. This shows that tirto.id has been able to provide objective information based on a number of factual things such as policies, field situations, and statements from experts. The impact is that the government is not consistent in implementing a policy, making people's trust in the government decrease, due to facts on the ground which show that there are still differences in treatment of someone in implementing a policy. This is shown in several warganet comments on the tirto.id Instagram account.
