Authors: Anggreini Olivia Puspita , Wildian Wildian
Published: March 2022

Telah dirancang sebuah perangkat pencacah gerak mencit (Mus musculus) yang berbasis Arduino Uno. Perangkat pencacah ini terdiri dari dioda laser sebagai sumber cahaya yang dihubungkan dengan baterai sebagai sumber tegangan dan sensor fotodioda sebagai transmitter. Pengolahan data pada perangkat ini menggunakan Â mikrokontroller dan LCD sebagai penampil dari data yang dihasilkan. Sensor fotodioda digunakan untuk mencacah yang memanfaatkan tegangan keluaran. Perubahan tegangan keluaran terjadi akibat adanya variasi cahaya yang didapatkan oleh sensor fotodioda. Tahapan uji coba perangkat ini dimulai dari uji coba sensor fotodioda dan uji coba perangkat pencacah. Hasil pengujian menunjukkan perangkat sudah dapat bekerja dengan baik, dimana pengujian terbaik pada mencit dengan berat badan 28 g yang memiliki persen error 0% sebelum dipengaruhi zat psikoaktif dan mencit yang memiliki berat badan 26 g memiliki persen error 1,4% setelah dipengaruhi zat psikoaktif. Persen error terbesar pada mencit yang memiliki berat badan 27 g yaitu 2,30% sebelum dipengaruhi zat psikoaktif dan dan persen error 1,52% setelah dipengaruhi zat psikoaktif. Dengan demikian, zat psikoaktif yang digunakan memperkecil jumlah cacahan mencit pada kendang yang membuktikan bahwa aktivitas mencit menjadi menurun.An Arduino Uno based mouse (Mus musculus) counter has been designed. This counter device consists of a laser diode as a light source and a photodiode as a light detector placed in a closed hexagonal housing with each side 10 cm long, 3 cm wide and 3 cm high. The digital data from the photodiode is processed by the microcontroller and the count results are displayed on the LCD. The testing phase of this device starts from testing the photodiode sensor and testing the counter device. The test results showed that the device was working properly, where the best test was on mice with a body weight of 28 g which had a 0% percent error before being influenced by psychoactive substances and mice with a body weight of 26 g had a percentage error of 1.4% after being influenced by psychoactive substances. The largest percentage error was in mice who weigh 27 g, namely 2.30% before being influenced by psychoactive substances and and 1.52% percent error after being influenced by psychoactive substances. This proves that the activity of mice decreased after being given psychoactive substances.

Published: March 2022

Penelitian ini membahas tentang sintesis lapisan antikorosi dengan menggunakan ekstrak daun ketapang sebagai inhibitor yang bertujuan untuk mengetahui pengaruh konsentrasi larutan inhibitor dan perubahan arus listrik terhadap lapisan nikel dan mengetahui nilai laju korosi dan efisiensi inhibisi dari ekstrak daun ketapang. Dalam penelitian ini pembuatan lapisan diawali dengan mencampurkan bahan NiSO4, borid acid dan aquades yang kemudian penambahan inhibitor dengan konsentrasi 0%, 0,5%, 1%, 1,5% dan 2% volume inhibitor. Pelapisan dilakukan dengan metode elektrodeposisi. Pengukuran laju korosi baja menggunakan larutan korosif dilakukan dengan mencampurkan 2gram NaOH 1M dan 50ml aquades. Pengujian laju korosi sampel dilakukan selama 6 jam. Nilai efisiensi inhibisi yang paling opimal didapatkan pada penambahan konsentrasi inhibitor 1,5% yaitu sebesar 92,96%, dengan laju korosi terendah yaitu 0,76 Mpy. Konsentrasi inhibitor yang menghasilkan permukaan lapisan paling seragam yaitu pada konsentrasi inhibitor 1% dengan nilai efisiensi inhibisi 80,25%. Dengan analisis laju korosi menggunakan metode weight loss didapatkan pengaruh penambahan konsentrasi inhibitor terhadap laju korosi, dimana semakin meningkatnya konsentrasi inhibitor pada saat deposisi maka laju korosi akan semakin turun.. Karakterisasi permukaan baja setelah elektrodeposisi dilakukan pada sampel terbaik dengan menggunakan Scanning Electron Microscopy (SEM) dan X-Ray Diffraction (XRD)Â  yaitu pada konsentrasi inhibitor sebesar 1% volume larutan. Karakterisasi dilakukan pada sampel sebelum dan setelah perendaman dalam medium pengkorosi.Â This article reports on the synthesis of an anti-corrosion coating using tropical almond leaf extract as an inhibitor. This research begins with the manufacture of layers using NiSO4, borid acid and distilled water. Then the addition of the inhibitor was carried out with a concentration of 0%, 0.5%, 1%, 1.5% and 2% by volume of the inhibitor. The coating was carried out by the electrodeposition method. The corrosion rate was determined by immersing the steel for 6 hours in a corrosive solution mixed with 2g NaOH 1M and 50mL distilled water. The most optimal inhibition efficiency value was obtained at the addition of the inhibitor concentration of 1.5%, namely 92.96%, with the lowest corrosion rate of 0.76 Mpy. The inhibitor concentration that produced the most uniform coating surface was 1% with an inhibition efficiency of 80.25%. Corrosion rate analysis using the weight loss method shows that the addition of inhibitor concentration reduces the corrosion rate. Characterization of the steel surface after electrodeposition was carried out using Scanning Electron Microscopy (SEM) and X-Ray Diffraction (XRD). Characterization was carried out on the samples before and after immersion in the corroding medium with the optimum surface yield atÂ  concentration of 1% inhibitor.Â

Published: March 2022

Colombia cuenta con el mayor número de aves registradas en el mundo y ocupa, después de Brasil, el segundo lugar en biodiversidad de especies vegetales. Por otro parte, el país presenta óptimas condiciones para la especie invasora Azadirachta indica, conocida como neem, introducida al país por sus propiedades insecticidas, usos medicinales y proyectos de restauración ecológica. No obstante, se desconocen qué funciones ecológicas puede estar cumpliendo. Hasta ahora se ha registrado que ciertas especies de aves consumen su fruto. Este trabajo aporta información sobre posibles actividades realizadas por la avifauna urbana con esta especie de árbol. La investigación se llevó a cabo entre octubre y noviembre de 2015, delimitando tres zonas ubicadas en San Salvador (Barranquilla), El Concord (Malambo) y sede norte de la Universidad del Atlántico (Barranquilla). Se utilizó el método de muestreo de punto fijo para dos momentos de observación: salida (07:00– 08:00 horas) y puesta de sol (16:00 – 17:00 horas). Se observaron 12 especies de aves con algún tipo de uso y aprovechamiento del árbol: percha, reposo, canto, acicalamiento y consumo del fruto. Concluimos que A. indica ha sido incorporado a las actividades de las aves en el entorno urbano, principalmente, como un sitio de descanso y estadía temporal. En menor medida puede ser una fuente de alimento para determinadas especies de aves con dietas omnívoras o enfocadas en frutos y semillas.

Corporations as legal entities or subjects can give a major contribution in increasing economic growth and national development, but there are times when corporations commit various criminal acts (corporate crime) that have a detrimental impact on the state and society. In reality, corporations can be a place to hide assets resulting from criminal acts that are not touched by the legal process in criminal liability. The problem of corporate responsibility as a perpetrator of a crime is not a simple matter, considering that a corporation is a legal entity, not a person who can be subject to imprisonment. In addition, the problem also stems from the principle of no crime without error (geen straf zonder schold). Mistakes are known as mens rea or bad intentions that naturally only exist in natural people.

 

Mens rea is an element that is difficult to prove from a corporation that is considered to have committed a crime, considering that corporations can only take action through the organ of board of directors. Corporations can be considered to have committed a crime based on the actions of the person who supervises the management of the corporation. On December 21, 2016, the Supreme Court stipulates Supreme Court Regulation Number 13 of 2016 concerning Procedures for Handling Criminal Cases by Corporations (Perma No. 13 of 2016). The existence of Perma Number 13 of 2016 has become the basis for law enforcement to be more confident in taking action against corporations that commit criminal acts. This study aims to find out how criminal responsibility can be charged to PT Nindya Karya (Persero) as a perpetrator of corruption and how to apply Perma Number 13 of 2016 in handling corruption cases committed by PT Nindya Karya (Persero).

 

The method used is normative research. The criminal liability that can be imposed on PT Nindya Karya (Persero) is the principal crime in the form of a fine with a maximum provision plus 1/3 (one third). The determination of PT Nindya Karya (Persero) as a suspect in a criminal act of corruption is a concrete step in law enforcement in Indonesia in ensnaring corporations as perpetrators of criminal acts. This determination is a breakthrough in law enforcement, especially for the Corruption Eradication Commission (KPK) after the issuance of Perma No. 13/2016 which can be used as a guide in the implementation of handling corporate crimes.
PERLINDUNGAN HUKUM TERHADAP AHLI DALAM PERKARA TINDAK PIDANA KORUPSI

Experts are often needed in efforts to eradicate corruption, for example to calculate and explain the magnitude of state financial losses as a result of corruption. Several experts who were presented by the public prosecutor in the corruption case were actually sued in a civil manner by the defendant because they were considered to have harmed him. The problem is how is the legal protection that can be given to experts in corruption cases, from the existence of legal demands both civil and/or criminal by parties who feel aggrieved? Article 32 paragraph 1 of the United Nations Convention Against Corruption, 2003 (UNCAC, 2003) has mandated the need for legal protection for experts, but if you look at the existing laws and regulations, the Criminal Procedure Code (KUHAP) does not regulate the protection of experts, thus also with the law governing corruption and the Draft Criminal Procedure Code. Legal protection for experts which is regulated definitively can be found in Article 28 paragraph (3) of Law Number 31 of 2014, but it still contains shortcomings, so that further it needs to be regulated in the Draft Criminal Procedure Code, by reformulating Article 40 paragraph (1) and make a new formulation so that the expert cannot be prosecuted criminally or civilly for the information given in good faith and contains the truth.

Authors: Cavalcante Filho José Renan Miranda , Spir Patrícia Rodrigues Naufal , Cortez Gustavo Maldonado , Malveira Adib Saraty , Gaia Felipe Franco Pinheiro
Published: March 2022

Background:

Histoplasmosis is a fungal disease endemic in some regions of the United States of America, Canada, and Latin America. The geographic characteristics, humidity, soil, and climate are responsible for such distribution. In Brazil, there are case reports of histoplasmosis throughout its territory, being considered an endemic region. It is considered an opportunistic disease, affecting mostly immunocompromised patients. To the present date, scientific publications dealing with pediatric cases of histoplasmosis are restricted to case series. Spinal cord injuries caused by histoplasmosis are rare, even in the adult population, being described in few studies.

Case Description:

The present report deals with a 4-year-old patient, from the southeast region of Brazil, who started a condition of fever, weight loss, cervicobrachialgia, and symmetrical tetraparesis, with evolution over 2 months. In the diagnostic investigation, she was found to have primary immunodeficiency and neuroimaging examinations showed a cervical spinal cord lesion at the level of C4-C6. The anatomopathological diagnosis of histoplasmosis was possible after surgery for decompression and biopsy of the lesion.

Conclusion:

According to our research, there are no reports in the literature that address the situation of spinal cord compression syndrome due to histoplasmosis in the pediatric population.
Korean Understandings of the Occupation Through Drama: Gaksital
Authors: Steinmeyer William , Maestrejuan Andrea
Published: March 2022

In this paper, I analyze the how the Korean media portray the nation’s experience during the Japanese Occupation from 1910 to 1945 in order to better understand modern Korean collective memory of the occupation. The following paper was originally part of a digital history project in which I analyzed multiple pieces of Korean media including manwha, film, and television. In this work, I dive deep into a single example of a wildly popular Korean television series called Bridal Mask to demonstrate how the Occupation is portrayed and how this impacts modern Korean’s views on the period. I approach this paper with a strong focus on the social implications of historical memory, and I specifically look for the intentional deviations from historical reality which are present throughout the series. Using a mixture of literary, social, and historical analysis, I attempt to parse how these deviations from reality contribute to the creator’s message. My goal is to illuminate modern political and economic tensions between Korea and Japan as part of a deeper social and historical rift and how nationalist media, such as Bridal Mask, contribute to the ongoing animosity.
Microbial Dehalogenation of Synthetic Organohalogen Compounds: Hydrolytic Dehalogenases
Authors: Leisinger Thomas , Bader Regula
Published: March 2022

Hydrolytic removal of halogen substitutents is commonly the first step in the degradation of haloaliphatic compounds by aerobic bacteria, whereas initial dehalogenation of aryl halides is rare. Hydrolytic dehalogenations are catalyzed by specific dehalogenases, a group of enzymes which
has been extensively studied in bacteria and which does not seem to occur in mammals. Questions pertaining to the origin and evolution of dehalogenases in soil bacteria have recently become tractable by the establishment of dehalogenase gene sequences. At the protein level, new dehalogenases
are being discovered and known dehalogenases are being analyzed with respect to their mechanisms of catalysis. Finally, microbial dehalogenases, either as cells of dehalogenative bacteria or as enzyme preparations, have potential for applications in environmental biotechnology and biotransformation.
Coordination Polymers of CuII with the Ligand Pyrazine-2,3,5,6-tetracarboxylic Acid
Authors: Graf Marion , Stoeckli-Evans Helen , Whitaker Claire , Marioni Pierre- Alain , Marty Werner
Published: March 2022

The ligand pyrazine-2,3,5,6-tetracarboxylic acid in the presence of CuCl2 and the buffers CH3CO2X/CH3CO2H, X = K+, Rb+, Cs+ and (CH3CO2)2Mg/CH3CO2H, forms two quite different types of coordination polymers. With the monovalent K+, Rb+, or Cs+ buffer an almost right-angled dimeric unit is formed which polymerizes to form a zig-zag polymer {Cs4[Cu2{pztc)22H2O]⋅9H2O}∞ (1). This 'dimerizes' about a center of symmetry to form a two-dimensional polymer sheet. With the divalent Mg2+ buffer a mononuclear unit polymerizes to form a quasi-linear polymer {Mg(H2O)6[Cu(pztc)2H2O]⋅2H2O}∞ (2). The X-ray crystal structures of 1 and 2 indicate that the Cu atom exists in two quite different coordination environments (NO3, square pyramidal for 1 and N2O2, square planar for 2) and that the Cu-N(pyrazine) bond distances are much longer than normal.
1,3-Disubstituted Ferrocene-Containing Thermotropic Liquid Crystals: Synthesis, Mesomorphic Properties and the Crystal and Molecular Structure
Authors: Deschenaux Robert , Kosztics Isabelle , Marendaz Jean-Luc , Stoeckli-Evans Helen
Published: March 2022

Two families of 1,3-disubstituted ferrocene derivatives have been synthesized and their liquid-crystal behavior investigated. Compounds of series I, (η5-C5H5)Fe[(η5-C5H3)-1,3-(COOC6H4OOCC6H4OCnH2n+1)2] (n = 1–14, 16, 18), exhibited remarkable mesomorphic properties. Indeed, nematic and/or smectic C phases, associated with large anisotropic domains, were observed. Derivatives of series II, (η5-C5H5)Fe[(η5-C5H3)-1,3-(COOC6H4OCnH2n+1)2] (n = 1-9), were found to be non-mesogenic. The crystal and molecular structure of Ih (n = 8) was determined by means of X-ray analysis. The crystallographic data confirmed both a highly anisometric structure for Ih and a compact arrangement of the molecules in the crystal. The present results have shown that a critical length/depth ratio of ca. 5-7 must be passed for obtaining liquid-crystal properties.
HADOKEN: An Open-Source Software Package for Predicting Electron Confinement Effects in Various Nanowire Geometries and Configurations
Authors: Wong Bryan , Chevalier Cameron
Published: March 2022

We present an open-source software package, HADOKEN (High-level Algorithms to Design, Optimize, and Keep Electrons in Nanowires), for predicting electron confinement/localization effects in nanowires with various geometries, arbitrary number of concentric shell layers, doping densities, and external boundary conditions. The HADOKEN code is written in the MATLAB programming environments to aid in its readability and general accessibility to both users and practitioners. We provide several examples and outputs on a variety of different nanowire geometries, boundary conditions, and doping densities to demonstrate the capabilities of the HADOKEN software package. As such, the use of this predictive and versatile tool by both experimentalists and theorists could lead to further advances in both understanding and tailoring electron confinement effects in these nanosystems.
