Prehrana kokoši obogaćena sušenom ili svježe ubranom biljkom Talinum triangulare: učinak na proizvodnju i lipidni profil jaja

This study investigated the comparative effects of administration of dried and fresh Talinum triangulare (Tt) plant supplements on the egg production and egg quality of laying hens. Two hundred and ten pullets, purchased at the age of 18 weeks, were randomly assigned to seven study groups: A1 , A2 , A3 ; B1 , B2 , B3 ; and C. Aqueous extracts derived from a dried sample of Tt were administered at 62.5, 250, and 1000 mg/L doses for treatment of Group A (A1, A2, and A3 ); or from freshly harvested samples of Tt at 62.5, 250, and 1000 mg/L dose for treatment of Group B (B1 , B2 , and B3 ). Hens in Group C (CC) served as an un-supplemented experimental control group. Laying rate and egg lipid profile were determined at two-month intervals following standard procedures. Supplementation with Tt significantly enhanced egg production, with extended higher laying rates in groups A and B. A significant (P<0.05) reduction in low-density lipoprotein (LDL) concentration and an increase in the high density lipoprotein (HDL) concentration of eggs were observed in the supplemented groups (A and B). Dietary supplementation with dried samples of Tt at doses of 250 and 1000 mg/L increased the number of eggs laid, and resulted in the production of eggs with lower LDL and higher HDL cholesterol. Further research is needed to elucidate the exact mechanisms behind the hypolipidemic principle and egg production enhancement.U ovom su radu istraženi komparativni učinci dodatka prehrani sušene i svježe biljke Talinum triangulare (Tt) na proizvodnju i kvalitetu jaja kokoši nesilica. Ukupno je 210 kokoši u dobi od 18 tjedana nasumično podijeljeno u sedam pokusnih skupina: A1 , A2 , A3 , B1 , B2 , B3 te C. Vodeni ekstrakti dobiveni od sušene biljke Talinum triangulare primijenjeni su u dozama od 62,5, 250 i 1000 mg/L u skupini A (A1 , A2 , and A3 ), dok su ekstrakti dobiveni od svježe ubrane biljke Tt u istim dozama primijenjeni u skupini B (B1 , B2 , i B3 ). Kokoši u skupini C (CC) poslužile su kao kontrolna skupina i nisu dobile dodatak prehrani. Stopa nesivosti i lipidni profil jaja određeni su u dvomjesečnim intervalima prema standardnim postupcima. Dodatak ekstrakta Tt prehrani kokoši znakovito je povećao proizvodnju jaja uz povećanu stopu nesenja u skupinama A i B. Osim toga znakovito je smanjena (P<0,05) koncentracija lipoproteina niske gustoće (LDL), a povećana koncentracija lipoproteina visoke gustoće (HDL) u skupinama koje su dobivale dodatak prehrani (A i B). Prehrana s dodatkom ektrakta dobivenog od sušene biljke Tt u dozama od 250 i 1000 mg/L povećala je broj snesenih jaja i rezultirala proizvodnjom jaja s nižim LDL-om i višim HDL-om. Potrebna su daljnja istraživanja kako bi se razjasnili točni mehanizmi koji se nalaze u podlozi ovog hipolipidemijskog principa i povećanja proizvodnje jaja

The Impact of Drug Abuse and Delinquency on Educational Environment Security

Creating and maintaining a secure and supportive educational environment is essential for the success and well-being of university students. This study investigates the interplay between drug abuse, delinquency, sociocultural factors, and the security of the educational environment. Drawing upon a sample of 356 students from the Federal State-Funded Institution of Higher Education—Tomsk State University of Control Systems and Radioelectronics (TUSUR), we employed a partial least squares structural equation modeling (PLS-SEM) approach to analyze the data. The findings indicate that sociocultural security significantly influences students' behavioral intentions, with a confirmed negative impact on the intention to commit delinquency (β = -0.461, p 0.05). Furthermore, the study reveals that students' behavioral intentions significantly affect the security of the educational environment. The intention to use drugs and the intention to commit delinquency negatively impact the security of the educational environment (β = -0.635, p > 0.05; β = -0.660, p < 0.05, respectively). These findings contribute to the understanding of the complex dynamics that shape the educational environment in universities. The study highlights the importance of promoting sociocultural security and fostering student well-being to prevent negative behavioral intentions and maintain a secure learning environment. Doi: 10.28991/ESJ-2023-07-05-018 Full Text: PD

Audit Tata Kelola Academic Information System Menggunakan Framework Cobit 2019

Pengelolaan sumber daya Teknologi Informasi yang baik efektif, efisien, dan terkendali menghasilkan value bagi sebuah institusi. Upaya untuk mendukung proses manajemen mengembangakan AIS sebagai alat untuk mengevaluasi arah kebijakan, kebutuhan fungsional, dan risiko belum diterapkan secara sempurna. Penelitian ini merupakan audit disertai analisis sistematis untuk mengukur tingkat kematangan sistem Academic Information System (AIS) di STIKES Guna Bangsa Yogyakarta menggunakan framework COBIT 2019. Fokus penelitian adalah pada tata kelola proyek pengembangan AIS yaitu pada proses pengelolaan sumber daya (EDM04) dan inovasi terkelola (APO04). Luaran yang diharapkan adalah sebuah rekomendasi untuk memaksimalkan proses pengembangan sistem menggunakan metode bertahap, yaitu observasi, data collection, data validation, dan identifikasi data maturity level. Audit dan analisis yang dilakukan penelitian ini menemukan tata kelola dalam pengembangan AIS kondisi saat ini berada pada maturity level 2 (managed process) dengan nilai EDM04 = 2,29 dan APO04 = 2,25. Artinya proses sudah dilakukan, tetapi hanya sekedar dilakukan sehingga kurang mencapai tujuan yang diharapkan. Hal ini ditandai dengan ada proses yang tidak lengkap dan tidak terorganisasi dengan baik. Untuk menuju maturity level yang maksimal yaitu level 5, penelitian ini merekomendasikan pengelola untuk melengkapi SOP yang akan dijadikan rujukan dan juga memperbaharui dokumen-dokumen sehingga mengikuti sistem yang dikembangkan sesuai teknologi terkini. Sebagai catatan tambahan lingkungan kerja yang kondusif perlu diciptakan guna mencapai inovasi yang maksimal sesuai dengan sumber daya yang dimiliki. AbstractGood management of Information Technology resources is effective, efficient, and controlled to produce value for an institution. Efforts to support the management process to develop AIS as a tool to evaluate policy directions, functional requirements, and risks have not been implemented perfectly. This research is an audit accompanied by a systematic analysis to measure the maturity level of the Academic Information System (AIS) system at STIKES Guna Bangsa Yogyakarta using the COBIT 2019 framework. The focus of the research is on the governance of the AIS development project, namely the resource management process (EDM04) and managed innovation ( APO04). The expected output is a recommendation to maximize the system development process using a gradual method, namely observation, data collection, data validation, and identification of maturity level data. The audit and analysis conducted in this study found that governance in the development of AIS is currently at maturity level 2 (managed process) with a value of EDM04 = 2.29 and APO04 = 2.25. This means that the process has been carried out, but only done so that it does not achieve the expected goals. It is characterized by incomplete and poorly organized processes. To reach the maximum maturity level, namely level 5, this study recommends managers complete SOPs that will be used as references and also update documents so that they follow the system developed according to the latest technology. As an additional note, a conducive work environment needs to be created to achieve maximum innovation following the available resources

Cybersecurity maturity assessment framework for higher education institutions in Saudi Arabia

The Saudi Arabia government has proposed different frameworks such as the CITC’s Cybersecurity Regulatory Framework (CRF) and the NCA’s Essential Cybersecurity Controls (ECC) to ensure data and infrastructure security in all IT-based systems. However, these frameworks lack a practical, published mechanism that continuously assesses the organizations’ security level, especially in HEI (Higher Education Institutions) systems. This paper proposes a Cybersecurity Maturity Assessment Framework (SCMAF) for HEIs in Saudi Arabia. SCMAF is a comprehensive, customized security maturity assessment framework for Saudi organizations aligned with local and international security standards. The framework can be used as a self-assessment method to establish the security level and highlight the weaknesses and mitigation plans that need to be implemented. SCMAF is a mapping and codification model for all regulations that the Saudi organizations must comply with. The framework uses different levels of maturity against which the security performance of each organization can be measured. SCMAF is implemented as a lightweight assessment tool that could be provided online through a web-based service or offline by downloading the tool to ensure the organizations’ data privacy. Organizations that apply this framework can assess the security level of their systems, conduct a gap analysis and create a mitigation plan. The assessment results are communicated to the organization using visual score charts per security requirement per level attached with an evaluation report

Diseño de hidrogeles basados en complejos biopoliméricos con capacidad de remoción de metales pesados

El presente trabajo realizó un acercamiento al diseño de hidrogeles de quitosano y alginato de sodio (Q:AS), con capacidad de remoción de metales pesados para su posible aplicación en sistemas modelo de suelos contaminados. La estrategia experimental se llevó a cabo en tres etapas. La primera etapa contempló el establecimiento de las condiciones óptimas para la obtención de hidrogeles mediante la determinación del número de equivalentes y potencial zeta de los biopolímeros, resultando las relaciones másicas (Q:AS) de 1:1 y 1:0.8 y un pH de 4 como óptimos para la coacervación. Bajo las condiciones mencionadas se sintetizaron hidrogeles de Q:AS, aplicando técnicas de agitación (AG), microondas (MO), ultrasonido (US) y MO-US, con la finalidad de identificar en las etapas posteriores del estudio, posibles mejoras a nivel estructural o en la capacidad de remoción de metales pesados por parte de los hidrogeles. Como resultado de la primera etapa se encuentra que se presentaron mayores rendimientos de material para la relación másica 1:1, además de un mayor rendimiento para la técnica MO-US en comparación con las demás técnicas aplicadas. La caracterización de los hidrogeles de Q:AS previamente sintetizados se llevó a cabo durante la segunda etapa, la cual contempló el análisis mediante Espectrometría Infrarroja con Transformada de Fourier (FTIR), reología y microscopía óptica. La microscopía óptica permitió identificar posibles mejoras a nivel estructural mediante el uso de US mientras que vía FTIR se logró establecer la formación efectiva de coacervados gracias al incremento de las señales asociadas a los grupos funcionales característicos de Q y AS (NH2+ y COO-), las cuales presentaron una mayor intensidad en los coacervados en comparación con los biopolímeros sin coacervar. La aplicación de AG, MO, US y MO-US podría eventualmente asociarse con los cambios en la intensidad de algunas señales (banda de 1082 cm-1), debido a que estas técnicas pueden ocasionar una ruptura en la estructura de los biopolímeros, conduciendo a la exposición de un mayor número de grupos funcionales y contribuyendo a una mayor reticulación en el hidrogel. El análisis reológico mostró un comportamiento de fluídos pseudoplásticos o reoadelgazantes en los hidrogeles sintetizados así como una diferenciación entre hidrogeles con mayor y menor estructuración dependiendo de la técnica de síntesis utilizada. La evaluación del secuestro de Pb2+ por parte de los hidrogeles de Q:AS se desarrolló a lo largo de la tercera etapa, en donde mediante el uso de espectrofotometría se evaluó el efecto de la concentración de Pb2+ y de la aplicación de AG, MO, US y MO-US. Durante la tercera fase se estableció que factores tales como la concentración inicial de Pb2+ y la síntesis de hidrogeles podrían tener un efecto significativo sobre la remoción de este metal pesado. El uso de US y MO-US mejoró significativamente el porcentaje de remoción de Pb2+ de la fase sobrenadante libre del hidrogel, por lo que es de suponer que estas dos tecnologías mejoran la capacidad de interacción de los biopolímeros y los iones metálicos

Irrigation water has been identified as one of the unusual inputs, which can severely restrict agricultural production and productivity unless it is carefully well-preserved and managed. It is a wide-ranging practice using every drop of water for crop production through suitable irrigation practices. Hence, a field experiment was conducted at Bekoji Negesso area for three consecutive years, 2020-2022 to evaluate the effect of deficit irrigation on yield and water productivity of onion (Allium cepa L.) under drip irrigation for small holder farmers during dry season. Drip irrigation with two treatments viz., 75% ETc and 50% ETc irrigation levels and full irrigation (control) were done. At an operating pressure head of 1.5 m, the average emitter flow rate was 0.43 liter/hr. Drip irrigation with 100% ETc gave the highest yield 34.31 t/ha as compared to 75% ETc and 50% ETc. Water productivity 10.13 kg/m3 were found highest at 75% ETc. The amount of water saved at 75% ETc and 50% ETc were 25 and 50 % respectively. And this would be sufficient to irrigate 0.33 to 1.00 ha of additional area of onion crop. The amount of water saved from 75% ETc could compensate the decrease in crop yield on additional 0.33 ha by using the 25% of saved water. Therefore, the study suggests farmers having limited amount of water for irrigation can adopt 75% ETc of drip irrigation
