Authors: Morlans Molina Marius , Ramos Pozón Sergio , Robles Olmo Bernabé , Montero Delgado Francisco
Published: March 2024

La investigación biomédica en los últimos años se financia fundamentalmente por la industria farmacéutica. Esta dependencia modifica las relaciones entre los centros, los equipos de investigación y las empresas del sector, creando condiciones para que proliferen los conflictos de intereses y sus potenciales consecuencias negativas, para las personas enfermas y para los sistemas de salud. En este contexto, los intereses y motivaciones de los investigadores tienen un papel relevante: identificar posibles conflictos y sus potenciales consecuencias negativas, y conocer los procedimientos preventivos cuando la mera declaración del conflicto no basta es imprescindible. En este sentido velar por el respeto a los principios éticos de veracidad, confiabilidad, responsabilidad e integridad debería ser una premisa de la comunidad científica, con el compromiso por parte de los centros de investigación en fomentar y garantizar que estos se cumplan. La declaración del conflicto de intereses es un primer paso y debería ser un procedimiento exigido a todos los investigadores no solo por las revistas científicas, sino por los comités directivos de los centros de investigación.
Implementation of Ministerial Regulations Based on Attribution Power in the Administration of Government
Authors: M. Yasin al Arif
Published: March 2024

This research aims to analyze the incompatibility of Ministerial regulations in the implementation of government which are formed based on attribution of power and intends to formulate a concept to prevent Ministerial regulations from resulting in regulatory obesity. The focus of this research is to answer the questions regarding the position of Ministerial regulations within the Indonesian legal system and how the incompatibility of Ministerial regulations based on attribution power affects the administration of government. This paper is a normative research using secondary data and literature study for data collection.The research findings indicate that firstly, within the legislative regulations system, Ministerial regulations are considered as delegated legislation or delegated regulations based on regulations above them. Secondly, through the independent authority of ministries and/or Ministers, a wide scope has been opened for creating regulations based on the independent authority of Ministers and/or ministries. This has resulted in an anomaly, namely the emergence of laws that provide attribution power to Ministers and/or ministries to directly create Ministerial regulations. This situation creates incompatibility in the administration of government because attribution power cannot be exercised by Ministers as assistants and mandate holders of the President.
Understanding European Union Climate Change Governance through Political Parties Euromanifesto
Authors: Nur Asrul Ibrahim
Published: March 2024

This study offers a novelty specifying climate change as the legislation results in the European Parliament (EP) as an indicator of the consistency of political groups in realising their Euromanifestos. The article aims to investigate precisely the prospects and future of climate change policies in the EU post the 2019 general election. This study adopted qualitative legal research methods by studying the Euromanifestos of political groups in the European Union that competed in the 2019 European elections. Environmental issues, particularly climate change, were a significant focus in the study of these manifestos. Based on data from Euromanifesto, this study selected five EU Regulations as indicators of realising such political promises. In addition, the record of legislation and the results of voting during the establishment of the regulation was also applied as a data source in this study. In general, the cohesion between political groups in the EP is excellent. Based on a manifesto study, there are three essential findings; namely, most political groups in the EP make environmental issues, especially climate change, a politicised issue in elections. The second finding is that there are specific intersections between political groups, so it has implications for making the issue of climate change a common interest, and the results of the vote showed that a majority of Member of European Parliament members supported the establishment of the regulation. Finally, the solidarity of the EP political group cohesion in establishing regulations related to climate change is the last finding in this research.
Think-pair-share based flipped classroom: A model for improving students’ learning achievement and self-efficacy
Authors: Samaila Kamaludeen , Tsong Chau Kien , Masood Mona , Bervell Brandford
Published: March 2024

The lack of clear instruction and teaching strategy during the in-class learning activities of flipped classroom (FC) model has affected the model’s efficacy. This study aims to improve FC model by proposing the think-pair-share-based flipped classroom model (TPS-FCM). This study investigates the effect of TPS-FCM on students’ academic achievement and self-efficacy in an information and communications technology (ICT) in education course. One hundred and seventy-three students were involved in the quasi-experimental study. The students in the experimental group (n=91) learned with TPS-FCM, and students in the control group (n=82) used the conventional flipped classroom model (CFCM). Pre-test, post-test, and survey were employed. Results showed that TPS-FCM significantly improved students’ ICT learning achievement and self-efficacy compared to CFCM. Gender was found to have been significantly affected by TPS-FCM in students’ learning achievement but not in self-efficacy. This study recommends think-pair-share (TPS) strategy to improve in-class activities in FC model. Moreover, the study has limitations because of using two different teachers, which might affect students’ learning achievement and self-efficacy. Nonetheless, this study contributed that integrating TPS into FC model improves in-class learning activities. Integrating TPS into the in-class learning activities proved the budding support to enhance the efficacy of FC model. Based on the results of this study, the authors suggested that flipped practitioners can use the think-pair-share strategy to minimize in-class issues, particularly the lack of clear instruction and teaching strategy. Many practical studies of FC model have already been conducted. The originality of this work is in the fact that it proposes a suitable strategy (TPS) to improve the in-class learning activities of the model. The study also explores the effect of the proposed model on students’ learning achievement and self-efficacy, which enrich the current literature.

Authors: Plotnikov A. V. , Komleva T. A. , Skripnik N. V.
Published: March 2024

The paper presents various derivatives of set-valued mappings,their main properties and how they are related to each other.Next, we consider Cauchy problems with linear homogeneousset-valued differential equations with different types ofderivatives (Hukuhara derivative, PS-derivative andBG-derivative). It is known that such initial value problems withPS-derivative and BG-derivative have infinitely many solutions.Two of these solutions are called basic. These are solutions suchthat the diameter function of the solution section is amonotonically increasing (the first basic solution) or monotonicallydecreasing (the second basic solution) function. However, the secondbasic solution does not always exist. We provideconditions for the existence of basic solutions of such initialvalue problems. It is shown that their existence depends on thetype of derivative, the matrix of coefficients on the right-handand the type of the initial set. Model examples are considered.
Development and exploitation of shape-generating molding tools made of polymer composite materials in the production of aircraft composite structures
Authors: Shevtsov Sergey , Snezhina Natalia , Kamchatny Alexander
Published: March 2024

The problem of rational design of the structure, manufacturing of shape-generating molding tools made of polymer composite materials and its use in forming thin-walled composite structures by vacuum infusion is viewed. Taking into account the requirement of minimum deformations of warping of the molded composite structure caused by residual stresses as a result of polymerization of the binder, the necessity of creating such equipment in two stages is justified. This implies both: a master mold making on CNC and producing the most open composite mold used for molding finished structures. Using the example of a thin-walled aircraft structure of complex geometry, the possibility of obtaining a process scheme and controlling the modes of manufacturing a composite mold and a part molded on it applying a developed computer modeling tool, that uses experimentally determined characteristics of components (reinforcing glass, carbon fabrics, thermosetting resins) and CAD models of the molded structure as initial information, is shown. The necessary experimental equipment, experimental technique and data processing to obtain the dependences of compressibility and permeability on the degree of binder filling of composite molds, and also on the ratio of externally applied compression and internal pressure, are viewed evidence from an 8-layer fiberglass preform T-10-14. For the consistent description of the viscosity of thermo-reactive resins, which evolves within the process and depends on temperature, degree of polymerization and time, a semi-empirical model is proposed, the parameters of which can be found in an empirical way by methods of differential scanning calorimetry and rheometry. The use of the developed computer modeling tool to maximize the level and equalization of the specific volume of the reinforcing component in the body of the molded structure, reducing the duration of the vacuum infusion process is illustrated by the example of three strategies for controlling external compression and vacuum pressures.

Published: March 2024

Soil bacteria have an effective role in dissolving soil potassium. Bacillus mucilaginosus plays an effective role in dissolving potassium in the soil so that the plant may absorb it easily. The present study aimed to test the efficiency of bacteria in dissolving potassium present in the soil surrounding the roots of crops. B. mucilaginosus was isolated and diagnosed from the rhizosphere soil of Celery, Wheat, Basil and Alfalfa plants. The diagnosis included studying the isolates' culture, microscopic and biochemical characteristics. The laboratory study also included testing the efficiency of these bacterial isolates in dissolving potassium compounds in Modified Aleksandrov agar medium and estimating the dissolution coefficient. The results of isolation and identification of bacteria isolated from 19 out of 50 soil samples planted with different crops (Celery, Wheat, Basil and Alfalfa) showed that 8 isolates could dissolve potassium. The results of the microscopic examination of these eight isolates showed that they were sticky in shape, positive for Gram-staining, forming spores and the capsule, while the movement examination showed that they were positive for these tests (movement test). The biochemical tests and cultural characteristics showed that the eight isolates bear the characteristics of B. mucilaginosus. The results showed that the dissolution coefficient of potassium for the different isolates ranged between 2.28 and 1.14, while the type of sugar added to the culture medium increased the efficiency of bacterial isolates for potassium solubility. The study demonstrated the bacteria's efficiency in the rhizosphere region in dissolving potassium, which helps the plant use it easily.
Application of data ratio analysis of lead accumulation in cartilage and bones of goats and chickens in Yogyakarta, Indonesia
Authors: Djohan Djohan
Published: March 2024

Cartilage and bones (CB) are primary organs for lead accumulation in domestic animals, but very few studies have addressed the occurrence of lead in both organs. CBs, especially from goat and chicken, although classified as non-edible food, are still being consumed by many local communities globally. Male goat and rooster were bought in traditional markets in Yogyakarta, Indonesia. Lead in CBs of humerus, radius, femur, and tibia (HRFT) were extracted by aqua regia digestible method and measured by Atomic Absorption Spectrophotometry. A set of data ratios, generated by data ratio analysis (DRA), namely concentration ratio (CR), amounts ratio (AR), variation ratio (VR), coefficient of variation ratio (CVR), joint probability (JP) and conditional probability (CP) based on the AR and CR, were determined to characterize the lead exposure in CB. The means of lead concentrations in CB in goat were 4.9 and 5.2 µg.g-1, and those in chicken were 5.00 and 5.20  µg.g-1, respectively. The CRs in goats and chickens were 0.95 and 0.96, and the ARs in goats and chickens were 1.34 and 1.16, respectively. A high linear relationship was found between Ln VR and Ln CVR, and the JP and CP supported decision-making on CB consumption. By targeting CB as primary organs for lead accumulation, considering its potential exposure for many communities, and comparing its further uses as animal feed, the DRA in this study is useful to provide broadened comparability in bioaccumulation studies.

Published: March 2024

Natural farming, a recent agricultural innovation emphasizing minimal inputs, helps boost crop production. While strawberries are conventionally cultivated, their natural farming potential remains untapped. In this regard,  an experiment was conducted to evaluate the influence of Subhash Palekar natural farming (SPNF) and conventional farming (CF) systems on the vegetative growth and yield performances of five different strawberry cultivars viz. Capri, Winter Star, Winter Dawn, Camarosa, and Nabila under field trials in the Doaba region of Punjab conditions. The experiment included ten treatments and was laid out in the factorial randomized block design employing five distinct strawberry cultivars (Capri, Winter Star, Winter Dawn, Camarosa, and Nabila) as factor I, and farming techniques - SPNF and CF - as factor II.  The results confirmed the supremacy of CF for vegetative growth and SPNF system for yield and yield attributing characters. Under the CF, cultivar Capri greatly outgrew other cultivars in terms of increased plant height (5.60 and 12.10 cm) and plant spread (14.87 and 23.63 cm EW; 13.00 and 24.59 cm NS) at 45 and 90 DAP, respectively. Contrarily, under the same farming method, the cultivar Camarosa displayed larger numbers of trifoliate leaves (4.80 and 14.50 at 45 and 90 DAP, respectively), chlorophyll index (56.90 SPAD), leaf area (45.84 cm2), and stem girth (2.45 cm). However, cultivar Capri produced the maximum fruits per plant (26.14) and yield per plant (328.53 g), while cultivar Camarosa resulted in the maximum average berry weight (16.53 g) and the greater yield efficiency (0.77 kg/cm2) under the SPNF technique.

Published: March 2024

Intertidal zones are crucial ecological interfaces, but there is a lack of comprehensive studies on mollusk communities in Surigao City, Philippines. This research aimed to assess intertidal mollusk profiles, including species density, diversity, evenness, and richness, addressing a knowledge gap in regional mollusk biodiversity. Using a belt transect quadrat method in three sampling areas during 2021, the study employed a descriptive correlation design to investigate relationships between mollusk profiles and seawater physico-chemical parameters (conductivity, dissolved oxygen, pH, salinity, and temperature). In Surigao City's Day-asan, Hikdop Island, and Sibale, 44 gastropod species (19 families) and 11 bivalve species (9 families) were identified. Conidae and Strombidae families dominated. Average seawater parameters were conductivity 51.33, dissolved oxygen 7.45, pH 7.84, salinity 32, and temperature 28.52. Day-asan exhibited the highest species count (49), followed by Hikdop Island (42) and Sibale Island (37). Hikdop Island had the highest species density and evenness, Day-asan had the highest species diversity index, and Sibale Island had the highest species richness. Mollusk profiles showed no significant differences between sampling areas, and a strong negative correlation between pH and species evenness was observed. Surigao City displayed diverse mollusk biodiversity, but a declining trend in diversity indices was noted. This study fills a critical knowledge gap in understanding mollusk community dynamics, providing essential baseline data for future conservation and management strategies in the region, while also shedding light on the impact of environmental factors on intertidal mollusk populations in Surigao City.

Published: March 2024

Fruit and vegetable processing byproducts have a high concentration of biologically useful components and nutritional fibre, though they are frequently discarded as manufacturing waste. The purpose of this study was to improve the nutritional value of the Indian recipe papad, a low-moisture dish with a thin, crisp, wafer-like texture, by utilizing the beneficial properties of dehydrated carrot pomace powder (CPP), which is usually discarded as a food industry bio-waste. Carrot pomace powder was prepared and examined for nutritional and functional properties (10, 20, and 30%), and the developed samples were coded as P0 (control, 100% black gram flour), P1 (black gram flour: carrot pomace powder; 90:10), P2 (black gram flour: carrot pomace powder; 80:20), and P3 (black gram flour: carrot pomace powder; 70:30). The physical, sensory, and storage properties of the developed value-added papads were evaluated. Adding CPP to the flour mix increased the moisture, ash, and crude fiber content while decreasing the protein and carbohydrate content. Based on sensory evaluation, sample P1 was found to be the most acceptable by the sensory panel. The product's microbiological studies showed that, up to a 30-day storage period, the product was well within safe limits. Based on the water activity (at 36.7ºC/ 83% RH) and overall acceptability scores, triple-laminated aluminum bags were considered an appropriate packaging material for storing the value-added papads. This study has established the incorporation of CPP as a healthier alternative to produce an inexpensive, fiber-rich, value-added papads.

Hingga saat ini, dualisme kelembagaan lembaga pengawas pemilu dan pilkada di Aceh masih terjadi. Kondisi tersebut masih menyisakan masalah dalam pelaksanaan pengawasan pemilu dan pilkada di Aceh. Artikel ini memfokuskan bahasan pada aspek pilihan kebijakan hukum yang dapat diambil untuk menyelesaikan dualisme tersebut. Penelitian ini merupakan penelitian hukum normatif yang sepenuhnya menggunakan data sekunder berupa bahan hukum primer dan sekunder. Kajian ini berkesimpulan bahwa akar persoalan dualisme lembaga pengawas pemilu dan pilkada di Aceh disebabkan tidak sinkronnya pengaturan UU Pemilu dan UU Pilkada dengan UU Pemerintahan Aceh. Hal itu juga diperkuat dengan Putusan MK yang menyatakan Pasal 557 dan Pasal 571 huruf d UU Pemilu bertentangan dengan UUD 1945 karena pembentukannya tidak sesuai dengan ketentuan perubahan UU Pemerintahan Aceh yang dimuat dalam UU Pemerintahan Aceh itu sendiri. Penelitian ini merekomendasikan agar dualisme kelembagaan lembaga pengawas pemilu dan pilkada di Aceh segera diakhiri melakukan perubahan terhadap UU Pemilu, UU Pilkada dan UU Pemerintahan Aceh

In the article, the authors turn to the practical side of the cultural policy of the Soviet government, which at the early stages declared the goal of forming a “new man'. The ideological discourse constructed ideal images, while the “reforging” of the population in the provinces was carried out in difficult material conditions. Based on archival materials, the study shows the experience of building and developing a library network in the Stavropol region. After analyzing the experience of organizing library work, the authors come to the conclusion that Soviet social engineering faced a number of difficulties, such as hunger, lack of specialists and scarce funding.
“Autocracy” and “absolutism”. On the problem of the prerequisites of the Basic State Laws on April 23, 1906
Authors: Kulikov Sergey
Published: March 2024

The article examines the semantic and legal prerequisites of the Main state Laws of April 23, 1906 as of 1894. The author believes that the semantic prerequisites are connected with the lack of identity between the concepts of “autocracy” and “absolutism”. The legal prerequisites are connected with the fact that long before 1906, autocracy was formally and actually limited in the field of succession to the throne, religion, judicial power, civil law, subordinate administration and local self-government.

Air dalam tanah bermanfaat bagi tumbuhan untuk pertumbuhan dan perkembangannya. Kapasitas tanah menahan air dipengaruhi oleh sifat fisik dan kimia tanah dari berbagai jenis penggunaan lahan. Sebagian besar lahan di Desa Karangpatihan berupa tegalan kering. Penentuan titik pengambilan contoh tanah dilakukan dengan menggunakan metode Purposive Random Sampling. Pengambilan sampel tanah terganggu dan tidak terganggu dilakukan pada tiga satuan penggunaan lahan yang meliputi tegalan, sawah, dan semak belukar dengan empat ulangan untuk setiap SST. Analisis data dilakukan dengan menggunakan analisis korelasi dan regresi menggunakan IBM SPSS Statistics 25 dan Microsoft Excel 2016 untuk menggambarkan kurva. Hasil penelitian menunjukkan bahwa satuan penggunaan lahan semak memiliki kemampuan tanah menahan air tertinggi. Faktor yang paling berpengaruh terhadap kemampuan tanah menahan air adalah bahan organik. Faktor lain yang berpengaruh nyata terhadap kemampuan tanah menahan air adalah tekstur tanah, berat isi tanah, porositas tanah, dan permeabilitas tanah.

Porang (Amorphophallus oncophyllus Prain) adalah salah satu jenis tumbuhan yang terdapat di Indonesia dari marga Amorphallus dan termasuk kedalam suku talas-talasan (Araceae). Kebutuhan yang tinggi akan porang tentunya membutuhkan lokasi pengembangan penanaman porang yang memadai. Salah satu daerah yang berpotensi menjadi daerah untuk pengembangan tanaman porang adalah Desa Sumberejo, Pasuran, Jawa Timur. Potensi yang ada tentunya harus diimbangi dengan faktor media tanam yang memadai. Pentingnya peranan bahan organik dalam mempengaruhi sifat fisik tanah membuat penelitian mengenai pengaruh dan dosis masukan bahan organik yang sesuai terhadap lahan pertanian Desa Sumberejo sangat diperlukan. Survei lahan dan pengambilan sampel dilakukan di lahan penanaman kopi dan sengon Desa Sumberejo, Purwosari, Pasuruan, Jawa Timur. Penelitian ini merupakan percobaan faktorial yang menggunakan Rancangan Acak Lengkap (RAL) dengan 2 faktor yaitu macam bibit porang dan kombinasi media tanam. Faktor pertama yaitu macam bibit porang yang terdiri dari 3 taraf sedangkan faktor kedua kombinasi media tanam yang terdiri dari 5 taraf. Kombinasi keduanya menghasilkan 15 kombinasi perlakuan dengan 3 kali pengulangan, sehingga didapati 45 plot perlakuan. Kombinasi media tanam terbaik ditinjau dari segi sifat fisika adalah perlakuan M3 yaitu Tanah 2 kg : Pupuk kandang 4 kg dengan karakteristik tekstur tanah lempung berliat, 1.12 g/cm3 berat volume, 2.26 g/cm3 berat jenis, 59.34% porositas tanah dengan kadar air kapasitas lapang sebesar 38.55%.

Secara umum permasalahan yang terjadi di pantai Pademawu pesisir selatan Kabupaten Pamekasan adalah abrasi yang mengakibatkan kerusakan pantai. Hal ini berdampak pada wilayah pesisir sepanjang Pantai Pademawu, yang berdasarkan data citra tahun 2006 dan 2017 telah mengalami abrasi sejauh 50m. Melihat kondisi seperti ini, Pusat Riset Kelautan, Kementerian Kelautan dan Perikanan melakukan penelitian tentang bangunan perlindungan pantai dengan menggunakan struktur lunak berupa prototipe teknologi Karung Geotekstil Memanjang (KGM) atau yang biasa disebut dengan Geotube. Geotube yang digunakan memiliki dimensi tinggi 1,5m, lebar 4m dan panjang 20m. Desain perlindungan pantai ini terbagi menjadi 4 segmen dimana setiap segmen terdiri dari 2 geotube (2x20m) dan jarak antar segmen sebesar 20m. Tujuan dengan pemasangan teknologi KGM ini adalah untuk memulihkan pantai yang tererosi yang berada di belakang struktur dengan harapan terbentuknya tombolo (sedimentasi) atau lahan timbul. Kriteria keberhasilan penerapan KGM ini hanya dapat diketahui dari hasil monitoring secara berkala setelah struktur tersebut dibangun. Dari hasil pengukuran dilapangan sejak September 2018-Maret 2019 terdapat penambahan tinggi timbunan atau sedimentasi mencapai 55cm.

Stres oksidatif dapat berkaitan erat dengan beberapa penyakit seperti Parkinson, Alzheimer, arterosklerosis, hipertensi dan diabetes. Antioksidan menjadi komponen penting untuk mengatasi stress oksidatif yang terjadi di dalam tubuh. Sumber antioksidan alami asal Provinsi Bengkulu yang telah didukung sebagai komoditas unggulan Pemerintah Provinsi yaitu jeruk kalamansi (Citrus microcarpa), jeruk gerga (Citrus reticulata) dan buah mangrove (Sonneratia alba). Ketiga komponen tersebut telah dijual dalam bentuk olahan makanan dan dikonsumsi oleh masyarakat. Meskipun demikian, aktivitas antioksidan dari ekstrak komoditas tersebut belum banyak dilaporkan. Tujuan penelitian ini yaitu menganalisis aktivitas antioksidan ekstrak jeruk kalamansi, jeruk gerga dan buah mangrove. Penelitian ini diawali dengan proses pembuatan ekstrak etanol dari ketiga komoditas tersebut dengan teknik maserasi. Setelah itu, aktivitas antioksidan dari ketiga ekstrak tersebut akan diperiksa dengan teknik 2,2-difenil-1-pikrilhidrazil (DPPH). Hasil pengukuran dengan DPPH dari ekstrak jeruk kalamansi, jeruk gerga dan buah mangrove dengan standar asam galat menunjukkan bahwa ekstrak buah mangrove memiliki aktivitas antioksidan terbesar (IC50 = 36,473 ppm) jika dibandingkan dengan ekstrak jeruk gerga (IC50 = 1257,77 ppm) maupun jeruk kalamansi (IC50 = 1593,72). Ekstrak buah mangrove memiliki aktivitas antioksidan lebih besar jika dibandingakan dengan ekstrak jeruk gerga maupun jeruk kalamansi.Kata kunci: antioksidan, jeruk, gerga, kalamansi, mangrove
