IMPACT OF SOME AGRONOMIC PRACTICES ON SOIL PHYSICAL AND HYDRAULIC PROPERTIES: AN OVERVIEW OF COMMON CASES STUDY IN SEMI-ARID ENVIRONMENTS
Authors: Mirko Castellini
Published: August 2024

The development and adoption of sustainable agronomic practices able to preserve and enhance the physical properties of soils and improve agroecosystem functions, with the aim of safeguarding of irrigation and meteoric water, is a challenge for both scientists and farmers. In this investigation a selection of some agronomic practices, common for the Mediterranean agro-environments, including conventional tillage and no-tillage at different soil depth, incorporation of wheat straw into the soil, as well as soil amendments with biochar, were considered. Selected experimental evaporation experiments, obtained under controlled laboratory conditions, were used to detect and summarize the main effect induced on water retention and soil permeability. The use of capacitive indicators, for which reference values of literature are available, e.g., relative field capacity (RFC), allowed to discriminate the effects induced by agronomic treatments, both in accordance with expectations and the results obtained in previous experimental investigations. Results of RFC have clearly highlighted the agronomic treatments that are most capable of modifying the water/air balance of the soil. This study represents an experimental contribution with a view to spreading knowledge on the sustainability of agronomic practices. It further confirms that the assessment of the sustainability of agronomic practices needs specific assessments repeated in space and time, considering long-term experiments.

This research was conducted to know the perception of farmers about the Integrated Farming System (IFS). The study mainly aimed to determine farmers’ knowledge, perception of IFS and constraints about it. A simple random sample method was used to select 100 farmers for the study. To measure the variables, appropriate scales were created. Based on a previously prepared questionnaire, data were collected through face-to-face interviews. The variables were described using descriptive statistics, such as mean, standard deviation, range, and percentage. The study revealed that 44% of the farmers used IFS on their fields and 46% have known about IFS through their friends where 17% have chosen “crop+animal” as their integration type. Most of the respondents acknowledged that IFS may increase economic diversification and ensure nutritional security. Most farmers agree that IFS can help ease the fodder issue and protect the environment. Farmers also have less risk sensation than conventional farmers do. Small and marginal farmers face difficult challenges and IFS is unable to effectively handle all these constraints. The findings of the research will be a good resource and guidelines to take any step for maximum utilization of our limited resources.

The challenge of reducing the greenhouse gas emissions (GHGs) for preserving the environment and increase the food production is one of the main challenges in the agricultural sector to face climate change impact. This challenge encourages the world for maximaizing the mineral fertilizers’ efficiency with the less utilized amount. This paper aims to evalualte the efficacy of Azolla on vegetative growth, fruit quality, yield and storability in zucchini with utilizing different rates of mineral fertilizers. The experiment was carried out in the experimental farm of Dokki site for Protected Agriculture, Ministry of Agriculture and Land Reclamation, Giza, Egypt, during two successive seasons of 2022 and 2023. Three different treatments of mineral fertilizers were applied on zucchini (Cucurbita pepo), which represented 100, 75 and 50% of the recommended dose of NPK. The applied fertilizer treatments were represented once with Azolla (soil addition at rate 5g/plant) and once without. The best vegetative and fruit properties, nutritional status of plants and yield of Zucchini were revealed by the recommended dose of mineral fertilizers (100%). The treated soil with Azolla indicated significant higher measurements such as growth, NPK content of plants, yield and properties of zucchini fruits compared with the untreated soil plants. The highest yield was recorded with the recommended mineral fertilizer dose and the treated soil with Azolla. The less mineral fertilizer treatment (75% of the recommended dose) with the treated soil of Azolla had achieved higher nutrient content, physical and chemical properties than using the recommended dose of mineral fertilizer without Azolla, however the recommended dose of mineral fertilizer without Azolla showed higher yield and fruit quality higher the 75% mineral fertilizers with adding Azolla. The highest nutrient use efficiency was performed with Azolla treatment and 50% of mineral fertilizer. The highest revenue and net profit appeared by 100% mineral fertilizers with adding Azolla, but with low to insignificant difference between the same fertilization dose with non-Azolla addition. While 75% mineral fertilizers with adding Azolla showed a high revenue and net profit with a significant difference (close to double) between the same fertilization dose with non-Azolla addition.

Published: August 2024

Comparative historical linguistics can show changes in languages that have kinship relationships. Analysis carried out on comparative historical linguistics can be both synchronous and diachronic. Diachronically the Javanese language has changed from time to time, namely Old Javanese, Middle Javanese, and New Javanese which are still actively used by the speakers. This article focuses on examining changes in phonological aspects of Javanese based on a diachronic review. To analyze the innovation and phonological retention of Proto Austronesian in Javanese, the historical-comparative method is used. The findings contained in this article are: (1) the PAN phoneme reflex can produce regular phoneme change rules (primary rules) in addition to sporadic rules (secondary rules) ); (2) there is some retention and innovation on PAN etymon. The retention of the Javanese phoneme to PAN appears in several consonant phonemes such as * / p /, * / b /, * / z /, * / j /, and / q /, and some vowels such as / a /, / i /, and / u /. Meanwhile, other phonemes are experiencing innovation, both innovation in the form of substitution, split, metathesis, mergers, dissimilation, protesis, and reduplication. Phonological and lexical innovations are significantly more dominant than retention.Linguistik historis komparatif dapat menunjukkan perubahan-perubahan pada bahasa yang memiliki hubungan kekerabatan.

Published: August 2024

Gober is one of the flagship programs on Prosalina FM that is highly favored by the public and has been running for over 20 years. The research aim to describe the communication patterns between the announcer and callers on the Gober program. The communication patterns under study include verbal language, the structure of message content, as well as the direction and intensity of interactions among participants. This research falls under the study of communication ethnography using a qualitative descriptive method. Data is collected by downloading from YouTube and then continued using non-participatory observation methods. The data analysis stage uses communication ethnography methods and analyzes the eight components of speech proposed by Hymes. The results of this study indicate that the communication patterns established on the Gober program differ when responding to new callers and regular callers. The communication pattern between the announcer and new callers is formal, predominantly using the Indonesian language, and of short duration. This is because the main goal of a new caller is to introduce themselves to fellow Gober listeners and to request a song. Meanwhile, the communication pattern between the announcer and regular callers is relaxed, full of familiarity, often using code-switching and mixing codes, and has a longer duration. This is because the main goal of a regular caller is simply to chat or engage in small talk in the morning with the announcer,Gober merupakan salah satu program acara unggulan di Prosalina FM yang banyak diminati oleh masyarakat dan telah berjalan selama lebih dari 20 tahun. Tujuan penelitian ini mendeskripsikan pola komunikasi penyiar dan penelepon pada acara Gober. Pola komunikasi yang dikaji berupa bahasa verbal, struktur materi pesan, arah dan intensitas interaksi di antara partisipan, dan latar sosial budaya. Penelitian ini termasuk kajian etnografi komunikasi dengan menggunakan metode deskriptif kualitatif. Data dikumpulkan dengan diunduh dari Youtube kemudian dilanjutkan dengan menggunakan metode observasi nonpartisipasi. Tahap analisis data menggunakan metode etnografi komunikasi dan analisis delapan komponen tutur yang dikemukakan Hymes. Hasil penelitian ini menunjukkan bahwa pola komunikasi yang dijalin pada acara Gober memiliki perbedaan saat merespons penelepon baru dan penelepon tetap. Pola komunikasi penyiar dan penelepon baru bersifat formal, dominan menggunakan bahasa Indonesia, dan berdurasi singkat. Hal itu karena tujuan utama seorang penelepon baru adalah untuk mengenalkan diri kepada sesama pendengar Gober dan untuk memesan lagu. Sementara, pola komunikasi penyiar dan penelepon tetap bersifat santai, penuh keakraban, sering menggunakan alih kode dan campur kode, dan berdurasi lebih lama. Hal itu terjadikarena tujuan utama seorang penelepon tetap adalah untuk sekadar mengobrol atau basa-basi di pagi hari dengan penyiar.
Improving efficiency of road transport through the use of hydrodiodes in hydraulic systems taking into account cavitation phenomena
Authors: Sokirko K. N. , Pavliuchenko E. A. , Lysenko E. A.
Published: August 2024

Introduction. One of the promising ways to reduce dynamic loads during operation of hydraulic crane manipulator installations is the use of hydrodiodes. In hydraulic systems operating at high speeds of the working fluid, cavitation phenomena may occur in the hydrodiode, which are accompanied by increased noise and vibration, and may lead to the destruction of the hydrodiode, which is not acceptable. The paper compares the results of calculating the flow of liquid in the flow part of a vortex hydrodiode, taking into account cavitation phenomena and without cavitation phenomena, with the results of research tests. The analysis of the effect of cavitation on the working processes in a vortex hydrodiode for crane manipulator installations is presented.Materials and method. Computational fluid dynamics (CFD) models using the FLUENT CFD code to study the working processes occurring in the working chamber of a vortex hydrodiode were developed. The commercial CFD code ANSYS FLUENT to simulate the flow of liquid in the flow part of a vortex hydrodiode was used.Results. The paper verifies the results of a numerical experiment with the results of research tests. A quantitative and qualitative analysis of the effect of cavitation on the working processes of a vortex hydrodiode has been carried out.Discussion and conclusion. It has been found that the values of pressure and diode in calculations taking into account cavitation and without cavitation practically do not differ, thus, the effect of cavitation at Reynolds numbers Re<30000 does not significantly affect the quantitative values of the parameters of the vortex hydrodiode and the cavitation calculation module can not be used. However, at higher values of the Reynolds numbers, cavitation appears in the working cavity of the vortex hydrodiode and the calculated values of the parameters of the hydrodiode without cavitation and taking cavitation into account differ significantly. Therefore, when calculating high-speed flows, it is necessary to use the cavitation calculation module. The analysis of the effect of cavitation on the working processes of a vortex hydrodiode showed that in the forward direction of the flow, cavitation does not significantly affect the parameters of the hydrodiode and the place of its formation, the upper inlet region of th tangential chamber. In the opposite direction of flow, cavitation has a significant effect on the pattern of fluid flow in the vortex hydrodiode. Cavitation covers almost the entire inlet volume of the radial tube and partially captures the central part of the vortex chamber

Published: August 2024

Introduction. The article deals with a problem relevant to the territory of our country – the calculation of the bearing capacity of ice crossings and winter roads. This problem is becoming more and more urgent in connection with the development of the northern territories, an increase in the carrying capacity of road transport and the volume of cargo traffic. At the same time, the construction of permanent roads and bridge crossings requires very large capital expenditures, which are not yet available for the Russian Federation.Methods and materials. A critical analysis of methods for determining by calculation the bearing capacity of ice cover at crossings (the maximum permissible load on the axle of a single car or road train) was carried out.The recommendations of normative and methodological documents on this issue are considered. The presented analysis of domestic and foreign publications made it possible to evaluate mathematical models of different levels of complexity and detail, with a different set of factors influencing the final result.Results. As a result of the research, a summary table, which contains formulas for calculating the bearing capacity of the ice cover, the parameters that are taken into account in these formulas, as well as the values of the bearing capacity calculated using these formulas for two temperatures: 0 °C and minus 20 °C has been compiled.Conclusions. According to the results of the analysis, it can be seen that the largest number of parameters is taken into account in M.M. Kazansky-R.A. Shulman; Q. Wang; ODM 218.4.030-2016 Methodological recommendations for assessing the carrying capacity of ice crossings’ dependencies. At the same time, the value of the bearing capacity, calculated according to the 11th formulas, varies by 2-3 or more times presented. Consequently, the presented mathematical models for predicting the carrying capacity of ice crossings require experimental verification on real objects by dragging the control cargo (with some refinement of this method).

Abstrak— Energi listrik saat ini masih menggunakan bahan bakar fosil. Indonesia merupakan negara tropis sehingga mempunyai kelebihan sinar matahari. Pemanfaatan sinar matahari dapat digunakan untuk pembangkit listrik tenaga surya, pembangkit listrik tenaga surya merupakan salah satu energi terbarukan dimana pemanfaatan cahaya matahari bisa diubah menjadi energi listrik. Intensitas cahaya matahari dan keadaan cuaca dapat mempengaruhi tegangan dan arus listrik yang dihasilkan dari panel surya.. Alat yang digunakan disini adalah sel surya, karena dapat mengkonversikan langsung radiasi sinar matahari menjadi energi listrik (proses photovoltaic). Agar energi surya dapat digunakan pada malam hari, maka pada siang hari energi listrik yang dihasilkan disimpan terlebih dahulu ke baterai yang dikontrol oleh SCC. Berkembangnya kebutuhan akan penyimpanan energi menyebabkan kebutuhan baterai semakin meningkat misalnya pada penggunaan baterai litium hal tersebut dikarenakan baterai litium ion memiliki banyak kelebihan mulai dari kerapatan energi yang tinggi hingga perawatanya yang mudah. Baterai lithium ion yang dihubungkan secara seri memberikan masalah teknis berupa ketidak seimbangan tegangan yang terjadi pada battery pack. Pada penelitian ini dibuat sistem penyeimbangan tegangan sel baterai dengan menggunakan topologi flyback converter arsitektur pack to cell, dimana energi pada pack yang memiliki tegangan paling tinggi akan ditransfer ke sel untuk menyeimbangkan tegangan antar sel. Battery pack yang digunakan memiliki konfigurasi 3S 5P, pada BMS yang dirancang memiliki tiga fitur utama yaitu monitoring, balancing, dan proteksi. Hasil pengujian menunjukan performa BMS untuk monitoring nilai tegangan dan nilai arus memiliki akurasi sebesar 99,99% dan 91,7%. Pada fitur balancing lama waktu yang dibutuhkan untuk melakukan penyeimbangan tegangan baterai bergantung pada besarnya perbedaan tegangan antar baterai dan banyaknya baterai yang memiliki nilai tegangan yang berbeda. Pada fitur proteksi dapat melakukan kinerja yang baik saat mengatasi masalah overcharge.

El objetivo fue evaluar las condiciones de acceso al agua y el saneamiento, así como la distribución y calidad del recurso hídrico a través de la medición de los niveles freáticos, el contenido de nitrato y bacterias de 16 puntos de control. La totalidad de muestras tomadas presentaron contenido de bacterias coliformes, por lo que, según el Código Alimenticio argentino, ninguna se considera apta para el consumo humano. Las concentraciones de nitrato fueron inferiores a los 45 mg NO3-/L considerado como límite para agua de consumo por el mismo código. Los resultados mostraron que el agua subterránea de consumo presenta contaminación antrópica debido fundamentalmente a un deficiente mantenimiento y gestión de los pozos de agua, además de un insuficiente tratamiento de los sistemas descentralizados de aguas residuales.

The rapid growth of the tourism industry in Indonesia has prompted the government to actively engage in efforts to develop the tourism sector to stimulate economic growth. One of the developments in the industry is the construction of the Southern Cross Road in several cities or districts. For example, Blitar Regency is renowned for its beautiful beaches, one of which is Pasir Putih Beach. This study measures the relationship between visitor satisfaction and future Behavior or recommendations to other tourists regarding destination image. Data for this study were obtained through questionnaires to individuals who have visited Pasir Putih Beach in Blitar Regency, with 200 questionnaires distributed. The data were analyzed using Structural Equation Modeling (SEM). The findings indicate that visitor satisfaction has a positive impact on destination image. Moreover, visitor satisfaction positively influences future Behavior in recommending Pasir Putih Beach to other tourists. Additionally, future Behavior positively impacts destination image and contributes to the economic benefits of individuals directly involved in tourism activities. Thus, an increase in tourist arrivals not only increases local revenue through tourism levies and taxes, but also creates business opportunities for local communities, creating a positive multiplier effect in the local economy around tourism destinations.

Indonesia is a country that has a disaster-prone geographic condition. This is because Indonesia is located at a confluence of tectonic plates, and the tropics have two seasons, namely rainy and dry. Disasters tend to occur in vulnerable communities, and will make communities more vulnerable. The vulnerability of a community begins with the unsafe physical, social and economic conditions attached to it. This insecure condition occurs due to internal and external dynamic pressure, for example in the local institutional community that is less developed and lacks the right skills. Disaster Management Policy is an integral part of national development, namely a series of disaster management activities before, during and after a disaster is carried out by the Malang Regency Government in its efforts to deal with frequent disasters which are not easy, in the implementation process many obstacles occur, disaster mitigation should routinely carried out to reduce the impact of disasters, and make people aware of disaster mitigation, one of which is by carrying out routine socialization on disaster mitigation starting from pre-disaster, during disaster and post-disaster, but BPBD Malang Regency rarely conducts outreach related to disaster mitigation, so that when disaster occurs Disaster impacts are far more severe and result in losses and cause casualties. Malang Regency Government needs to strengthen collaboration with other stakeholders for disaster mitigation efforts.

The purpose of this writing is to assess the community participation in Kabupaten Banyumas in utilizing E-Government media, analyze the supportive and inhibiting factors in the implementation of E-Government, and evaluate the efforts made by the Kabupaten Banyumas Government in overcoming these challenges. This qualitative research involves a literature review. The research process includes gathering primary and secondary literature sources, data processing, citation extraction, and abstraction to present research findings. Interpreting these findings generates comprehensive information, leading to knowledge acquisition for conclusive insights. The results of the discussed research reveal that Lapak Aduan Banyumas is an effective and efficient communication medium between the community and local government through social media, enhancing community participation in politics. Besides, uneven network infrastructure, particularly inadequate transmission towers and fiber optic cables in the hilly areas of Kabupaten Banyumas, results in unsatisfactory website-based service delivery.
We don’t need a science of animal consciousness. On the unexpected insights gained from Walter Veit’s “A philosophy for the science of animal consciousness”
Authors:   Institute of Philosophy, University of Białystok, Kittel (f. Białek) Maja
Published: August 2024

This paper is a critical commentary on Walter Veit’s book "A philosophy for the science of animal consciousness." My goal is to show that although Veit succeeds in presenting a compelling account of animal consciousness, he may have unintentionally undermined the purpose of such science. I argue that, despite the author’s claims, his theory is not as empirically grounded as he makes it out to be. Paradoxically, some of Veit’s arguments against his opponents seem to be double-edged. Still, I also argue that this is a necessary cost, as an alternative would be to succumb to a particular form of metatheoretical anthropomorphism. In effect, we end up with a surprising conclusion that we need many sciences of different consciousnesses, which seems at odds with Veit’s Darwinian continuity assumption. However, this only goes to show that the book is well worth discussing.

Ömer Seyfettin’s Short Story “The Rainbow”: A Precursor of Transgender Narratives
Authors: Gürova Ercan
Published: August 2024

Ömer Seyfettin, the founder of the modern Turkish short story and a widely read literary figure, published “The Rainbow” (“Eleğimsağma”) in 1917 in a magazine. The story revolves around a ten-year-old girl, Ayşe, and her gender transformation as part of a struggle against masculine hegemony and suppression. Although this transformation takes place through the protagonist’s dream, Seyfettin successfully showcases how gender roles and stereotypes become central in building respectful, acceptable, and powerful personas in society. The story also helps to question the so-called domestic roles of women by juxtaposing the responsibilities of the two genders based on existing cultural norms. To this end, this study aims to investigate how established gender roles in a patriarchal society are called into question and how gender fluidity defies stereotypical understanding of gender representation in a male-dominated society. The analysis of this gender transformation in the story will be made through the concept of performativity which has been introduced by Judith Butler. Though biologically female, Ayşe enjoys activities such as riding, wrestling, shooting, and playing in the streets, which are almost always associated with the male gender. Furthermore, she is subjugated to societal and religious pressure to act like a girl and cover her body. In this respect, Ömer Seyfettin’s “The Rainbow” can be hailed as a leading narration that puts gender performativity in the limelight at the beginning of twentieth-century Turkish literature.
