A Novel UV-Vis Spectrophotometric Method for Quantifying Rifaximin: Method Development and Validation
Authors: Raut Shibani , Amat Geetanjali , Mishra Akshya Ku
Published: July 2024

This study evaluated the standardization and method validation of rifaximin using different acid and phosphate buffer conditions (pH 1.2, 6.8 and 7.4). Although all tested conditions showed excellent precision (less than 2% RSD), limitations in linearity and precision were observed. Although the correlation coefficients were high (0.9898 to 0.9972), they deviated from the ideal (1.0), indicating possible nonlinearities. Accuracy ranged from 89.45% to 94.16%, indicating slight under- or overestimation of rifaximin concentration. These limitations compromise the reliability of the rifaximin quantification method. Other optimization strategies are recommended, including exploring different pH conditions, refining the concentration range of the standard curve, and considering alternative analytical methods such as HPLC when possible. By addressing these limitations, a more robust and reliable method for rifaximin standardization can be achieved.

Superior varieties are one of the technological components that are very important in achieving high production. The use of nitrogen fertilizer is the most important factor for plant growth and development. Chemical fertilizers in general and nitrogen fertilizers in particular are important determinants of productivity levels per unit area, and the importance of increasing the use of chemical fertilizers in soil conditions that lack organic matter. The research was carried out from February 2023 to May 2023 at Agro Techno Park, Jatikerto Village, Kromengan District, Malang Regency. The research was carried out in the form of a factorial experiment arranged in a Randomized Group Design (RGD). Consists of 2 factors, where the first factor is three varieties of glutinous corn and the second factor is the dose of nitrogen fertilizer. The first factor, varieties which consist of 3 levels, namely: Arumba Variety (V1), Srikandi Variety (V2), and URI 1 Variety (V3). The second factor, nitrogen fertilization dosage with 4 levels, namely: No fertilizer/Control (A0), Nitrogen 100 kg ha־¹ (A1), Nitrogen 200 kg ha־¹ (A2), and Nitrogen 300 kg ha־¹ (A3). Overall, the variety treatment and N fertilizer dose showed a significant interaction effect on all growth parameters except for the number of leaves at 42 DAP, and leaf area at 14, 21, 35 and 49 DAP. The variety treatment and N fertilizer dose showed a significant interaction effect on all yield parameters except ear length. Variety treatment and N fertilizer dosage had an influence on the analysis of increasing starch, amylose and amylopectin content. The Srikandi variety had the highest yield in every growth and yield of glutinous corn followed by the Arumba and URI 1 varieties. In the treatment with a N fertilizer dose of 300 kg ha־¹ had the highest yield in every observed parameter.

Authors: Escalante Jiménez José Luis
Published: July 2024

La integración y regulación de la Inteligencia Artificial (IA) representa un desafío a nivel mundial. Por ello, la presente investigación pretendió identificar la actitud y percepción de los estudiantes universitarios de educación ante el uso de la IA. El método se aplicó en un enfoque cuantitativo con un diseño descriptivo transversal, de corte básico. Se eligió una muestra representativa de 124 estudiantes universitarios de la facultad de educación (Licenciaturas en educación inicial, primaria, matemáticas, lengua y literatura para secundaria-Instituto Superior de Formación Docente Salomé Ureña, República Dominicana). A esta muestra se le aplicó un instrumento ad hoc con 21 ítems de selección múltiple, dividido en 6 dimensiones. El nivel de confiabilidad del instrumento es de.780 en la escala de Alfa de Cronbach, la cual se considera alta. Los principales resultados demuestran que los estudiantes sin la orientación de los docentes tienen la IA como recurso de estudio y generación de textos, y también ven la IA como aliada para su proceso de aprendizaje. Asimismo, entienden que la apertura de los docentes es baja para la integración y aceptación de la IA. Se concluye que la integración de la IA es muy frecuente en la formación docente de estos estudiantes. La IA implica un reto para los docentes, porque necesitan tener más formación y apertura en este sentido, y que la universidad tiene que diseñar planes y proyectos para la integración y formación de los estudiantes en el uso de la IA.
Situación de las mujeres rurales colombianas y su acceso a la tierra
Authors: Villamizar Acosta Camila
Published: July 2024

El presente artículo producto de un análisis documental, tiene como objetivo revisar la situación de la mujer rural colombiana respecto a la tenencia de tierra. Se muestra la existencia histórica de una gran desigualdad en su distribución, y cómo ha sido el germen de múltiples conflictos armados que se han presentado en Colombia desde el siglo XX y que, a pesar de diversos intentos por mitigarla, a través de reformas agrarias, persisten, evidenciando el fracaso de dichas iniciativas. También se muestra que la mujer rural tiene un acceso menor que los hombres a la tierra, producto de factores culturales y dinámicas patriarcales, que hacen de ellas un sector social altamente vulnerable. A partir del análisis, se concluyó que en Colombia persiste un gran desnivel en la repartición de tierra, comprobado por medio de un coeficiente Gini de .89; que muestra la existencia de una clara diferencia en la tenencia de este bien según género, ya que los hombres la poseen en mayor cantidad que las mujeres; que la informalidad en su posesión continúa siendo alta, situación que afecta en mayor medida a las mujeres, y dificulta su acceso a créditos y asistencia técnica, lo que no les ayuda a salir de la pobreza.
Loyalty to influencers and brands: Does negative publicity matter?
Authors: Bari Andriansyah , Angguna Welan Mauli , Izzati Astika Ulfah , Anindea Frianka
Published: July 2024

This study examines the critical role of trust in influencer marketing, focusing on how influencers' expertise, authenticity, and homophily affect followers' trust and subsequently their loyalty to influencers and brands. Utilizing an explanatory quantitative cross-sectional non-experimental design, data were collected from 202 consumers who purchased products such as cosmetics, skincare, and gadgets after watching influencer reviews. The data were analyzed using structural equation modeling (SEM). The results indicate that authenticity, expertise, and homophily significantly contribute to building trust among followers, with authenticity being the most influential factor. Meanwhile, physical attractiveness does not significantly impact trust. Furthermore, trust serves as a crucial mediator, enhancing the effects of influencers' expertise, authenticity, and homophily on both influencer and brand loyalty. Interestingly, negative publicity does not significantly moderate the relationship between trust and loyalty, suggesting that cultural and emotional factors in the Indonesian context may mitigate its impact.
Fuzzy C-Means Algorithm Modification Based on Distance Measurement for River Water Quality
Authors: ‘Uyun Shofwatul , Sulistiyowati Eka Sulistiyowati , Jati Tirta Agung
Published: July 2024

River water quality could be determined by understanding the capacity of pollutants in a water body. Fuzzy C-Means (FCM) is one of the fuzzy clustering methods for determining river water quality by measuring water quality parameters, that is, dissolved oxygen (DO) and total dissolved solids (TDS). The FCM algorithm is an effective fuzzy clustering algorithm for grouping data but often produces local and inconsistent optimal solutions due to the partition matrix's random initialisation process.  Therefore, this study proposes to modify the FCM algorithm to be precise in the partition matrix initialisation process using several distance concepts. The purpose of the proposed algorithm modification is to get more consistent FCM clustering results and minimise stop iterations. The validation process for the clustering results uses the FCM algorithm, and the FCM modification algorithm uses three parameters, namely the Partition Coefficient Index (PCI), Partition Entropy Index (PEI) and Silhouette Score (SS). The experiments were conducted with three replications and using various distance concepts. The results showed that the number of iterations stopped in the FCM algorithm has different values for PCI, PEI, SS, and stop iterations and objective functions in each trial. On the contrary, the FCM modification algorithm has consistent PCI, PEI, and SS values, and the number of iterations stops with fewer iterations. Therefore, the modified algorithm for initialising the partition matrix can be used in the fuzzy C-means clustering algorithm.

The Lion Air JT610 Crash Due to Lack of Pilot Training: Is There Responsibility for Indonesia?
Authors: Ghaisani Amalina , Sefriani Sefriani , Safitri Alya Ananda
Published: July 2024

This research analyses international law, specifically in the realm of international aviation law. This research aims to determine whether Indonesia is responsible for the crash of Lion Air JT610 that happened on October 29, 2018. The accident was also followed five months later by the crash of Ethiopian Airlines ET302 on March 10, 2019. Both crashes involved the Boeing 737 MAX 8 and were linked to inadequate pilot training on the new Maneuvering Characteristics Augmentation System (MCAS). Using the normative legal research with statutory and case approach, the findings proved that besides its responsibility as a regulator, Indonesia is only responsible for issuing the airworthiness certificate, supervision, and investigation. On the other hand, the responsibility to ensure the maximum level of flight safety remains in the hands of the manufacturer company, including conducting pilot training and providing information regarding the new system.

Intergenerational Cooperation and Justice between Age Groups
Authors: Bognar Greg
Published: July 2024

In this paper, I bring together the problems of justice between age groups and intergenerational cooperation in light of real-life demographic trends. I begin by presenting a simple model of intergenerational cooperation based on indirect reciprocity and show how cooperation can break down due to exogenous factors, including demographic change. I use the model to make the argument that principles for justice between age groups must be sensitive to the stability of intergenerational cooperation. I illustrate my thesis by considering the debate between distributive and relational egalitarians on justice between age groups.

To ensure the sustainability of forest ecosystem products and services, changing people’s perspectives and increasing their awareness of these resources and services is crucial. Determining people’s perceptions and opinions regarding ecosystem services is critical to this context. This study aims to assess the knowledge levels and views of individuals living in both urban and rural areas of Kastamonu province in Turkey regarding forests and the ecosystem services they provide. Data for the research were collected through 97 face-to-face surveys conducted in urban and rural settings. Differences in participants’ opinions based on their place of residence were analyzed using Kruskal-Wallis and Mann-Whitney U tests. The study results reveal that when people think of forests, the top three associations in terms of importance are nature and wildlife (41.8%), clean air (15.5%), and wild food (7.6%). Regarding the importance of forest ecosystem services, the ranking is as follows: regulatory services (39.2%), supporting services (28.2%), provisioning services (25.1%), and cultural services (7.5%). To ensure the sustainable use and continuity of forest ecosystem services, voluntary payment tendencies per capita are approximately 846 TL/person for the general population, 413.8 TL/person (24,8 $) for rural residents, and 1443.3 TL/person (86,4 $) for urban dwellers in Kastamonu. The total voluntary payment tendency for Kastamonu amounts to 318414942 TL (19066762 $).

Ramsay Modeli ile Orman İşletme ve Fidanlıklarının Toplam ve Kısmi Faktör Verimlilikleri: İstanbul Orman Bölge Müdürlüğü Örneği
Authors: Kaya Güven , Ok Kenan , Porsuk Tuncay
Published: July 2024

Türkiye’de devlet orman işletmelerinin verimliliklerinin ölçümüne yönelik birçok araştırma olmasına rağmen, uygulamaya yansımamıştır. Uygulanabilir ve muhasebe verilerine dayanan verimlilik hesaplama yöntemlerinin geliştirilmesi gerekmektedir. Bu makalede İstanbul Orman Bölge Müdürlüğüne bağlı 10 orman işletme müdürlüğü ve 2 fidanlık müdürlüğünün kısmi verimlilik, çok faktörlü verimlilik ve toplam faktör verimliliği ölçütlerinin Ramsay modeli kullanılarak hesaplanması, bulguların karşılaştırılması ve daha iyi yönetim uygulamalarına yönelik iyileştirme yollarının tartışılması amaçlanmıştır. Analizler işletmelerin ve fidanlıkların 2018-2022 yılları arasındaki döner sermaye hesaplarına dayanmıştır. Her bir kısmi verimlilik ölçüsünde farklı bir yönetim birimi diğerlerinden iyi durumdayken, toplam ve ayrıntılı verimlilik ölçülerinde Demirköy işletmesi öne çıkmıştır. Ayrıca Ramsay modeli bulgularının; işletmelerin sahip olduğu normal, toplam orman alanı veya ağaç serveti düzeylerinden bağımsız değerlendirilemeyeceği görülmüştür. Literatürde yer alan ve orman işletmeleri için daha önce kullanılmış fiziki ve parasal verimlilik ölçütlerine kıyasla Ramsay modelinin; muhasebe verilerine dayanması ve hesaplama kolaylığı açılarından orman işletmeleri ve fidanlıklar için gerekli verimlilik ölçümleri için uygulanabilir ve pratik bir fırsat sunduğu görülmüştür. Bununla birlikte, yapılan fark analizleri, işletme ve fidanlıklar için hesaplanan değerlerin farklı olduğunu ortaya koymuştur. Sonuç olarak Ramsay modelinin, tüm orman işletmeleri ve fidanlıklarda verimlilik ölçümleri yapmaya uygun olduğu ancak kurumsal yönetim etkinliği ve kurumlar arası başarı sıralaması yaparken, yapısal farklılıkların dikkate alınması gerektiği görülmektedir.

Published: July 2024

Biofuel production and utilization are becoming more widespread around the world. One environmentally friendly and economically viable feedstock considered for biofuel production is orange peels (zest). Previous research has documented the viability of using orange oil as an additive for aviation-grade fuel. It has been determined that it is acceptable to mix as much as 15% by volume of treated orange oil with current jet fuels without performance degradation. Prior to mixing with conventional jet fuel, the orange oil must be treated to avoid excessive soot formation during combustion. Hydrogenating the orange oil prior to mixing with jet fuel will diminish this problem. This article reports the results of a senior-student project, in which the processes of orange oil extraction, hydrogenation, and the conversion of orange oil into biodiesel fuel were reviewed. A small amount of biodiesel fuel was produced using orange peels as feedstock. The orange peels collected from several juicer establishments initially had a wet mass of 5130 grams. The peels were dried by the process of sun drying to remove unwanted water. This resulted in a net production of 6.79 ml (5.7 g) of orange oil through steam distillation. We were able to produce 0.03 ml (0.025 grams) of biodiesel fuel in less than 11 weeks. The measured heat of combustion of the biodiesel fuel was 33.65 MJ/kg. The scale of orange peel-based biofuel production must be increased by several orders of magnitude to make this process economically feasible. Key words. Orange Peels, Biofuel Production, Aviation Fuel, Heat of Combustion

This research aims to analyze the maturity level of Electronic-Based Government Systems, both at the National, Central and Provincial Levels in 2022 using quantitative data sourced from the Decree of the Minister for Empowerment of State Apparatus and Bureaucratic Reform Number 108, 2023 concerning Results of Monitoring and Evaluation of Results Electronic Based Government. The quantitative data analysis technique used is descriptive statistical techniques, while the evaluation technique covers four SPBE domains, eight SPBE aspects, and forty-seven SPBE indicators. The research results show that the SPBE maturity level at the national level is 2.40, at the central level is 2.49 and at the provincial level is 2.37. The three SPBE indices show that the Indonesian SPBE process is at the managed level, while the SPBE service is at the interaction level. This means that both the managed level and the interaction level show that Indonesia's SPBE is still far from the optimal level. Based on these findings, it can be recommended to policy makers that economic institutions as a value and bureaucratic reform as a modern organization are more optimized in their implementation.

Novice voters are susceptible to political misinformation, which can influence democratic decision-making. Thus, reducing the negative impact of political misinformation is essential to support more democratic elections. Utilizing the Stimulus-Organism-Response theoretical framework, this research examines four hypotheses concerning the correlation of media literacy and information literacy on the capability of novice voters to recognize misinformation about politics and their intention to disseminate it on social networks. A quantitative research approach employing cross-sectional surveys was utilized. The sample consisted of 380 novice voters comprising high school students in Cianjur Regency, selected through a stratified random sampling method. Data were collected through online surveys using Google Forms and tested using the application of the Statistical Package for the Social Sciences. According to the findings, media literacy and information literacy simultaneously significantly impact novice voters' competence to recognize political misinformation on social network sites, and higher media and information literacy scales correlate with lower intentions to disseminate political misinformation on social platforms. The findings conclude that media literacy and information literacy perform a crucial function in determining the behavior of beginner voters regarding political misinformation on social media. These findings also support policymakers, media organizations, and educational institutions in designing more effective literacy programs.
