ABSTRACT

Indonesian people still make rice as the main food-producing crop. Rice production shows a significant increase in almost all regions. Thus, many farmers depend on rice farming for their livelihoods, and still run their businesses on a small scale. With a relatively small business scale, causing income derived from rice farming is also relatively lower. The purpose of this study was to analyze the characteristics of farmers and the profile of rice farming, analyze cultivation technology, use of production factors, production, production costs, and rice farming income. Data analysis methods used are descriptive qualitative and quantitative descriptive. The results showed that rice farming was the main occupation of most farmers. The average age of rice farmers is 39.7 years (productive age group). The majority of farmers' education is graduated from junior high school. The average number of dependents is 3-4 families, and farming experience is around 6 to 10 years. Partial land ownership is own land with an average land area of 0,37 Ha. The condition of rice farming is quite good, it's just that there are problems with irrigation that cause farmers to only depend on rainwater. The rice farming revenue is IDR 10.219.500 / growing season which is obtained from the production of 2.271 kg/planting season, with a production cost of IDR 7.037.582 The benefit gained is as much as Rp 3.181.918 / planting season. The efficiency of rice farming is 1,45, which means that rice farming is already profitable.

Profiling Molecular Simulations of SARS-CoV-2 Main Protease (Mpro) Binding to Repurposed Drugs Using Neural Network Force Fields
Authors: Gupta Aayush
Published: July 2020

With the current pandemic situation caused by a novel coronavirus disease (COVID-19), there is an urgent call to develop a working therapeutic against it. Efficient computations can minimize the efforts by identifying a subset of drugs that can potentially bind to the COVID-19 main protease or target protein (MPRO). The results of computations are accompanied by an evaluation of their accuracy, which depends on the details described by the model used. Neural network models trained on millions of points and with unmatched accuracies are the best approach to employ in this process. In this work, I first identified and described the interaction sites of the MPRO protein using a geometric deep learning model. Second, I conducted virtual screening (at one of the sites identified) on FDA-approved drugs and selected 91 drugs with the highest binding affinities (below -8.0 kcal/mol). Then, I conducted 10 ns of molecular dynamics (MD) simulations using classical force fields and classified 37 drugs to be binding (including Lopinavir, Saquinavir, and Indinavir) based on the RMSD between MD-binding trajectories. To drastically improve the dynamics profile of the 37 selected drugs, I used the highly accurate neural network force field (ANI) method trained on coupled-cluster method (CCSD(T)/CBS) data points and performed 1 ns of binding dynamics for each drug with the protein. Using this approach, 19 drugs were qualified based on their RMSD cutoffs, and based on free energy (ANI/MM/PBSA) computations, 7 of the drugs were rejected. The final selection of 12 drugs was validated based on an MD trajectory clustering approach where 11 of the 12 drugs (Targretin, Eltrombopag, Rifaximin, Deflazacort, Ergotamine, Doxazosin, Lastacaft, Rifampicin, Victrelis, Trajenta, Toposar, and Indinavir) were confirmed to exhibit binding. Further investigations were performed to study their interactions with the protein and an accurate 2D-interaction map was generated. These findings and mappings of drug-protein interactions are highly accurate and may be potentially used to guide rational drug discovery against COVID-19.

Authors: Rizaldy Taslim Pinzon  , Vanessa Veronica
Published: July 2020

DLBS1033 is a lumbrokinase earned from extraction of earthworms, Lumbricus rubellus. Lumbrokinase has 2 main activities: fibrinolytic and fibrinogenolytic – these activities reduce blood viscosity and platelet aggregation. With all of those properties, DLBS1033 will be a promising agent in patients with ischemic stroke. The objective of this research is to identify the advantage of DLBS1033 in ischemic stroke patients' clinical outcome. We used Pub Med, Cochrane, and Clinical Key as our major database for this systematic review. "DLBS1033", "lumbrokinase", and "stroke" keywords selected to particularize the search. The 2 authors calculated each of the studies using Jadad score. Only certain studies with scores above 3 will be included for further review using PRISMA checklist. There were 27 studies relating to DLBS1033 or lumbrokinase and stroke. Further examination by 2 authors resulted in 23 articles being removed leaving 2 studies. Subjects in all of the said studies are ischemic stroke patients; predominantly male patients. All of the said studies compare DLBS1033 with standard therapy; either utilizing DLBS1033 as an additional therapy or as a separate therapy. Clinical outcomes were measured using NIHSS and BI. Compared to standard therapy, DLBS1033 proved successful in improving clinical outcomes among patients with ischemic stroke. It's also found to be safe with none serious adverse events and significantly has lower bleeding events.
Drug repurposing and it’s implications in therapy: an overview
Authors: Blessy Mariyam Babu
Published: July 2020

Drug Repurposing is finding new use of an already existing drug. It offers affordable, cheap and faster treatment. Drug repurposing has an additional advantage over new drug development because it lowers drug development costs as toxicity and other measures, including clinical trials, have already gone through them. However, there are few barriers which need to overcome like legal and economic barriers. Alternative drug development strategies are now being explored, such as the repurposing of existing drugs used to treat other diseases. This can save a considerable amount of time and money since the pharmacokinetics, pharmacodynamics and safety profiles of these drugs are already established, effectively enabling pre-clinical studies to be bypassed. Awareness and encouragement can promote the flourishing of drug repurposing, which holds a great future in the modern medical sector. Improvements in health care and nutrition have caused impressive improvements in life expectancy worldwide. Repurposing is an accelerated drug development path since existing drugs have clinical and pharmacokinetic evidence. New approaches to drug discovery, such as the re-use of patented medicines that are used to cure other diseases, are under debate. This can save significant time and money because these drugs' pharmacokinetics, pharmacodynamics, and safety profiles are already known, potentially enabling pre-clinical studies to override.
DIN MEMORIA ISTORIEI: EVAGRIE PONTICUL ȘI OPERA SA ÎN PREOCUPĂRILE PATRIARHULUI IUSTIN MOISESCU

Published: July 2020

The year 2019 was dedicated to paying homage to one of the foremost servants of the Romanian Orthodox Church – patriarch Iustin Moisescu. This was a good opportunity for us to bring back to light writings which relate to his preoccupations with the teachings of the Church Fathers. These preoccupations originate as early as the time of the courses attended in the “Miron Patriarhul” Seminary in Câmpulung Muscel, which he graduates as valedictorian, followed by the Faculty of Theology in Athens, where he goes for four years, between October 1930 and July 1934. Following this fruitful period, he prepares his doctoral thesis entitled “Evagrius Ponticus. Life, Writings and Teachings” which he presents in 1937 in Athens, under the guidance of the distinguished Greek patrologist Dimitrios Balanos. This paper was graded as exceptional.

The Three Holy Hierarchs Basil the Great, Gregory the Theologian and John Chrysostom, whom the Church honours particularly and under whose protection the large family of Christian theological education, and not just it, has placed itself, year after year, entered the conscience of the Orthodoxy as “equal in habits to the Apostles” and “teachers” or educators “of the world”. Their contribution to the growth of the Church teaching consists in the fact that they formulated a theological word representing, truly, a radical change in the core habits of the man of their time. They did not ignore the human wisdom of various times and, especially, the Greek thinking of the Antiquity, but went beyond this wisdom, reviewing human life based on the evangelical principles.

The Coronavirus Disease of 2019 (COVID-19) that is transmitted through the human respiratory system has a very high infection rate worldwide, including Indonesia. To cut off this outbreak, Indonesia has implemented some social distancing strategies that have an impact on the significant decrease of economic growth rate and the increase of poverty rate. To meet basic needs, people should continue their work in the middle of COVID-19 fear. Informal workers are among the most vulnerable groups to COVID-19 transmission because they frequently interact with the outsiders and find it difficult to comply with the health protocols. One way to prevent the COVID-19 transmission is the use of Personal Protective Equipment (PPE) such as masks, face shields, and gloves. Although these products to some degree are effective in preventing transmission, several risks that may endanger its users, such as incorrect or excessive use, incorrect maintenance, bad PPE design, and others. Therefore, this research aims to analyze the risks of the COVID-19 PPE and review the prevention recommendations for these risks. Risk analysis was carried out using the Failure Mode and Effect Analysis (FMEA) to analyze the use of masks, face shields, and gloves for the context of general informal workers in Indonesia. There are 5 aspects analyzed: product design, preparation for use, use, storage, and disposal. Based on the analysis, there are 10 mask risks, 15 face shield risks, and 12 gloves risks that need to be considered by informal workers and PPE designers and manufacturers as well.

Authors: Sitompul Carles , Ariningsih Paulina Kus , Setiawan Fran
Published: July 2020

Recent developments on the worldwide spread of Corona Virus Diseases-19 (COVID-19) show the vulnerability of human beings to pandemic risks in terms of biological, social, and economic factors. While human lives are the most important factor, a proposed solution dealing with pandemics should be sustainable which also includes other factors. Quarantines and physical distancing have been seen as effective ways to slow down the spread of COVID-19.  We therefore propose a market scheduling model with multi-objectives to support physical distancing minimizing the number of people in a certain area in a given time (crowds) and minimizing the virus spread rates. An analytical model is proposed and solved for Bandung City. The results show some promising ideas on how to slow down the virus spread without compromising both health and economic objectives. The future potential research of the model is also presented.
Prediksi Akhir Pandemi COVID-19 di Indonesia dengan Simulasi Berbasis Model Pertumbuhan Parametrik
Authors: Pratikto Fransiscus Rian
Published: July 2020

This research aims to predict the end of the COVID-19 pandemic in Indonesia based on parametric growth models. The models are chosen by considering their fitness with the data of Taiwan which is believed to have passed over the peak of the pandemic and have gone through all phases in the growth curves. The models are parameterized using the nonlinear least squares method. The deviation and confidence interval of each parameter is estimated using the k-fold cross-validation and the bootstrap techniques. Using the total cases per million population data from March 2 to June 18, 2020, it was found that two growth models fit the data, i.e. logistic and modified Gompertz, where the latter performs better. Using the information about the deviation of each model parameter, a simulation model is developed to predict the time at which the total cases curve starts to flatten, which is an indication of the end of the pandemic. It was found with 95% confidence level that based on the modified Gompertz model the pandemic will end somewhere between March 9 – September 7, 2021 with total cases per million of 206 - 555. Meanwhile, based on the logistic growth model, the end of the pandemic is between August 28 – September 23, 2020 with total cases per million of 180 - 375. This model can be extended by making comparative scenario with Taiwan based on measures that represent the quality of the pandemic mitigation such as test ratio and the intensity of social restriction.

El presente artículo busca presentar las reflexiones derivadas del estudio “Narrativas de agentes interventores en torno a la atención del abuso sexual infantil”, el cual tuvo como objetivo comprender las narrativas que se configuran en agentes interventores en torno a la atención de casos Abuso Sexual Infantil. Para ello se elaboraron escenarios conversacionales, enmarcados en el método de hermenéutico interpretativo, con el fin de favorecer la construcción de manera conjunta de narrativas a partir de la deconstrucción de los relatos dominantes y saturados expresados por los actores de la investigación, quienes fueron tres agentes interventores con experiencia en la atención de casos de abuso sexual infantil. Los resultados visibilizan diversas narrativas en torno a su proceso autorreferencial, el cual está inmerso en su rol como agente interventor, viéndose de esta manera afectado por experiencias personales y laborales. Asimismo, se establecen narrativas de satisfacción con su labor, ya que cuentan con recursos internos y externos, como los lineamientos establecidos por la institución, recursos de autoorganización, como la llamada “memoria” y el trabajo interdisciplinar, que resalta en la labor de intervención de casos de abuso sexual infantil. Por otro lado, se manifestaron posturas sobre el rol de la familia, la cual, si bien en ocasiones puede ser dominante y problemática, también se le reconoce su capacidad de cambio y la importancia de esta para el trabajo en la prevención.
Unfreezing change as three steps: Rethinking Kurt Lewin’s legacy for change management
Authors: Cummings Stephen , Bridgman Todd , Brown KG
Published: July 2020

© 2015, © The Author(s) 2015. Kurt Lewin’s ‘changing as three steps’ (unfreezing → changing → refreezing) is regarded by many as the classic or fundamental approach to managing change. Lewin has been criticized by scholars for over-simplifying the change process and has been defended by others against such charges. However, what has remained unquestioned is the model’s foundational significance. It is sometimes traced (if it is traced at all) to the first article ever published in Human Relations. Based on a comparison of what Lewin wrote about changing as three steps with how this is presented in later works, we argue that he never developed such a model and it took form after his death. We investigate how and why ‘changing as three steps’ came to be understood as the foundation of the fledgling subfield of change management and to influence change theory and practice to this day, and how questioning this supposed foundation can encourage innovation.

DENITRIFICATION KINETICS OF PSEUDOMONAS STUTZERI AZ101
Authors: Idi Ahmad
Published: July 2020

Nitrogen removal from environment is significant due to its effect on health and the whole ecosystems. Hence a highly nitrogen tolerant aerobic denitrifier, Pseudomonas stutzeri AZ101 was isolated from aquaculture wastewater and characterized using 16S rRNA analysis. The ability of the isolate to carry out simultaneously nitrification and denitrification (SND) was investigated. Different initial concentrations of nitrate and ammonium were used to determine the rate of SND. The denitrification data fitted well with the second order reaction kinetics with correlation coefficient between 0.923-0.9588. The nitrification data does not fit to both first and second order reaction kinetic but progressive shifts in the logarithm phase of the growth were observed at different initial concentrations. The kinetics data provide a significant insight to nitrogen removal from the wastewater.

Communication is defined as the flow of information in its simplest form. Utilizing the indicators and referring to another situation with the help of these indicators while providing its flow is a result-oriented study discipline. This discipline is defined with the name of Semiology and it is a field of science based on meaning.  Semiotics, shaped by behavior patterns "coded" by a particular society, it is associated with the process of interpretation. The fact that codes come together and form a whole of meaning unity and cause influence on different fields such as literature, advertising, cinema, caricature, painting and architecture. Hence, semiotics, which forms a message to be transmitted to the other party, possesses an extensive field of study. The meaning, interpretation and association of these messages with different factors fall within the scope of this discipline. Especially in order to comprehend that architecture is a communication tool, the physical factors and the approaches of the society producing these approaches should be reviewed together. This highlights the place of interior design in semiotics. In this study, interior design is evaluated within the scope of semiotics and a place reading is performed.

DEMOCRATIC POLITICAL SYSTEM IN THE PERSPECTIVE OF MAQASID SHARIA : STUDY ANALYSIS OF YUSUF AL-QARADAWI’S THOUGHT
Authors: Islamy Athoilah , Ziaul Haq Sansan
Published: July 2020

Abstract: one of the big issue that is still debatable about the relationship between Islam and politics is how legitimate the democratic political system is in the paradigm of Islamic law. This study will explain the alternative paradigm in evaluating the democratic system based on the paradigm of Islamic law from a prominent Muslim intellectual named Yusuf al-Qaradawi. This research is a qualitative research in the form of literature review. The primary source used is a variety of literature that explains Yusuf al-Qaradawi's thoughts about democracy in Islam. The method used is the method of interpreting the thoughts of the figures with the maqasid al-shari‘ah approach. There are two big conclusions of this research. First, Yusuf al-Qaradawi's view of democracy can be said to be grounded in its epistemological foundation in understanding the concept of an Islamic state. For al-Qaradawi, an Islamic state is a system of government that provides policy improvisation space in the benefit of social, economic and political life based on the objectives of Islamic law (maqasid shari'ah). Second, Yusuf al-Qaradawi's view, the democratic system can be compatible with Islam if the principles in the democratic system are in accordance with various values which are the spirit of the objectives of Islamic law (maqasid shari'ah), such as the value of justice, equality of rights, freedom, etc. so. To realize this, the democratic system must carry a holistic vision and mission, which includes worldly and ukhrawi benefits as well as individual and social benefits.       Keywords: Validity, democracy, Yusuf al-Qaradawi, maqasid shari’ah;

Bahasa merupakan alat komunikasi dan berinteraksi antar sesama Dalam interaksi sosial ini sudah menjadi keniscayaan adanya saling memengaruhi di antara bahasa-bahasa yang digunakan. Bahasa yang mayoritas digunakan akan bertahan dan mempersempit ruang gerak bahasa-bahasa lain yang jarang digunakan oleh penuturnya. Oleh karena itu, tujuan penelitian ini adalah menganalisis faktor-faktor penyebab kepunahan bahasa daerah dan memberikan gambaran tentang kondisi penggunaan bahasa daerah di tanah rantau dengan pembatasan pada Bahasa Bugis (BB) di pulau Lombok. Penelitian telah dilakukan pada bulan Maret sampai dengan Agustus 2017 di Labuhan Haji Lombok Timur. Pertimbangan pemilihan lokasi penelitian didasarkan oleh letak geografis yang termasuk salah satu daerah yang banyak dihuni oleh perantau asal Sulawesi Selatan. Hasil penelitian menunjukkan bahwa Bahasa Bugis sebagai bahasa interaksi intrasuku Bugis di Lombok masih sering digunakan oleh penutur suku Bugis. Hal ini berarti bahwa Bahasa Bugis sangat sulit ditemukan di pulau Lombok. Bahasa daerah dapat terus hidup dan berkembang dengan menjadikannya berprestise dengan cara mendorong seluruh anggota keluarga untuk tetap berusaha berbahasa daerah sebagai bahasa komunikasi pertama di dalam keluarga. Penelitian ini merekomen-dasikan perluasan sampel penelitian untuk dikembangkan supaya gambaran detail tentang kondisi bahasa Bugis di Lombok dapat terpetakan lebih memadai.

Participatory variety selection trials were conducted in 2018 G.C in Laelay-maichew, Tahtay-maichew and Ahferom districts of central zone of Tigrai to evaluate the performance of improved bread wheat (Triticum aestivum. L) Variety and to assess farmers’ criteria for bread wheat variety selection. Six improved bread wheat varieties (Mekelle-1, Mekelle-2, Ogolcho, Kingbird and Hedasse) including the most popular variety ‘Kakaba’ were used for the study at eighteen farmers (six from each district). The experiment was laid out using randomized complete block design at baby trial with three replications. Analysis of variance revealed a significant difference among the tested varieties for most of the agronomic traits except for kernels per spike and harvest index in all the tested locations. In the preference ranking, farmers used their own traits of interest which were very important in their wheat varieties for selection. Hence, common criteria’s identified by the farmers to select the best varieties were; grain yield, biomass yield, earliness, disease resistance, spike length and seed size. Accordingly direct matrix ranking by farmers showed that Ogolcho was top ranked both at L/maichew and Ahferom followed by Kakaba, however Mekelle-1 was first ranked followed by Kakaba at T/maichew.  Therefore farmers of L/maichew and Ahferom were recommended to use Ogolcho and Kakaba, whereas Mekelle-1 was recommended for T/maichew.
Performance of Wheat in Five Soils of Different Textures under Freshwater and Wastewater Irrigation

This study investigated the effects of five soils of different textures on wheat cultivation under irrigation with freshwater (FW) and municipal wastewater (WW). The experimental design was a split-plot with irrigation water quality as main factor and soil texture as sub-factor in three replications. These factors respectively comprised 2 and 5 treatments. Soil texture significantly (p£0.05) influenced plant height, leaf area index (LAI), spike length, number of grains per spike, above ground dry matter (ADM), grain yield, straw yield and biomass yield of wheat in most cases both under FW and WW irrigation. The harvest index (HI) of wheat responded significantly under FW irrigation only. Under FW, treatment T5 (silt loam) produced the highest grain yield (4.2 t ha–1) followed by T3 (loam-1) (3.1 t ha–1); the lowest yield (2.0 t ha–1) was in the control treatment, T1 (loamy sand). Under WW, treatment T2 (sandy loam) produced the highest grain yield (5.0 t ha–1) followed by T4 (loam-2) (4.5 t ha–1) both of which are statistically similar; the lowest yield (3.4 t ha–1) was in the control treatment. Treatments T2 and T4 provided the highest straw yield (5.6 t ha–1) and treatment T2 provided the highest biomass yield (10.6 t ha–1), both under WW; both T2 and T4 produced invariant biomass yields. Compared to other treatments, T2 and T4 gave statistically similar but significantly higher water productivity with respect to straw and grain yields. The lowest water productivity was in treatment T1 under both water qualities. The results of this study provided sound criteria in selecting suitable lands for wheat cultivation based on irrigation water quality, specifically in alluvial plains where soil texture is prone to high variations. Also, the observed facts of improved productivity of lower quality coarse-textured soils due to addition of easily available and inexpensive clay would provide guidance to bring unproductive sandy soils under production by clay amendments.
