TECHNOLOGIES TO REDUCE EMISSION OF METHANE AND NITROUS OXIDE IN RICE FIELDS: A BRIEF REVIEW
Authors: Wihardjaka Anicetus
Published: February 2023

Climate change caused by increasing anthropogenic greenhouse gas concentrations can threaten food security. Agricultural land is a source of food availability, however it is one source of GHG emissions, especially methane and nitrous oxide. Integration management of land, water, and plants in an integrated manner can be an effort to reduce the impact of climate change. This paper aims to inform the technologies to reduce emissions of methane and nitrous oxide in rice fields. One of the technologies to mitigate greenhouse gas emissions on agricultural land is through the use of natural materials as an inhibitor for the formation of methane and nitrous oxide in the soil due to the content of secondary metabolites in natural ingredients. Natural materials can simultaneously increase nitrogen nutrient uptake and improve crop yields. The methane production in rice fields is suppressed by more than 30% by coconut fiber, turmeric rhizomes, leaf of Ageratum conyzoides, and the leaf of Cosmos caudatus; while application of Cosmos caudatus and Ageratum conyzoides can also reduce the production of nitrous oxide more than 20%, respectively.

Rhizobacteria isolated from plant roots have the ability to produce siderophore compounds. These compounds play a role in inhibiting the growth of pathogens by binding to iron (Fe3+) which is needed by pathogens in their development. This research was aimed to find out the siderophore-producing bacteria isolated from local Kamba rice plants and their potential as biocontrol agents. Among the 28 isolates that were successfully isolated from the Kamba local rice rhizosphere, 10 isolates had the potential to produce siderophores with different morphological characters. The test was carried out to see the bacterial isolates capabilities to produce siderophores from two types of siderophores namely catechol and salicylate types. For the catechol type, the highest concentration of siderophore was found in the KBA8 bacterial isolate with 10.990 mg L-1, while the lowest was in the KBA1 bacterial isolate with only 5.876 mg L-1. The salicylate type siderophore with the highest concentration produced 9.493 mg L-1 was from the RKGU15 isolate and the lowest was found in KBU14 isolate which produced only 2.994 mg L-1. The isolates included in the Gram-positive group were 4 isolates while the Gram- negative group were 6 isolates and 90% isolates were able to produce the enzyme catalase. The results of this study indicate that all bacterial isolates can produce siderophores so that they have the potential as biocontrol agents to support environmentally friendly and sustainable agriculture.

East Nusa Tenggara Province has land that tends to be dry, with several superior local fruit commodities such as oranges, mangoes, avocados, and jackfruit. One of the local fruit-producing centers in East Nusa Tenggara is North Central Timor (TTU) Regency. Most of the fruit needs in TTU Regency are supplied from West Miomaffo District, especially Saenam Village. Saenam Village produces 222 Kg of local fruit while Sallu Village is 345 Kg, but the sales volume value of Saenam Village is higher than Sallu Village with a difference of Rp. 1,000,000. Based on these conditions, this study focuses on the comparison of local fruit farming businesses in Saenam Village and Sallu Village. The purpose of this study is to compare and analyze the sales volume, relative market share level, and business position of local fruit commodities by applying BCG analysis. The results showed that the fruit business in Saenam Village had a total sales volume in 2018 of IDR 2,151,313, 2019 of IDR 1,915,296, and 2020 of IDR 2,175,685. Meanwhile, Sallu Village has a total sales in 2018 of Rp 1,009,821, 2019 Rp 899,584, and 2020 Rp 887,281. The market growth rate and relative market share are calculated based on the total sales volume. The results of the BCG analysis show that Saenam Village is in the star quadrant, with a market growth rate of 1.31% and a relative market share level of 2.57. Sallu Village has a market growth rate of -15.25% and a relative market share rate of 0.4. This value explains that the fruit products of Sallu Village are in the dog quadrant. The strategy that needs to be carried out by farmers in Saenam Village is to expand fruit marketing. The strategy that can be applied by farmers in Sallu Village is to replace fruit gardens with vegetable gardens in order to increase income and use land more optimally.

Authors: Deligoz Ilyas
Published: February 2023

Cucumber mosaic virus (CMV) is one of the most destructive viruses that affect pepper all over the world. Using resistant varieties is one of the most effective ways to control the virus. Identification of new resistance sources is essential for the development of resistant cultivars. In the present study, the reactions of 50 Capsicum genotypes (25 Capsicum baccatum, 15 C. annuum and 10 C. frutescens) were determined against CMV-Sa isolate with mechanical inoculation under controlled conditions in 2020. A 0–4 disease rating scale was used to analyze the genotypes, and the genotypes were categorized as resistant, moderately resistant and susceptible based on disease incidence and disease severity scores. The findings revealed that there were significant (p < 0.01) differences in disease incidence and severity among genotypes. The study demonstrated that one of the 25 tested C. baccatum genotypes (KTB-11) found to be resistant, and three genotypes (KTB-29, KTB-34, KTB-57 and KTB-72) were rated as moderately resistant to CMV. However, it was determined that all tested C. frutescens and C. annuum genotypes were susceptible to CMV. The genotypes identified as resistant and moderately resistant can be used as a source of resistance in pepper breeding studies.

Published: February 2023

Juniper species are especially used in traditional medicine due to their analgesic, diuretic, antibacterial, antimicrobial, anti-inflammatory, and liver-protective effects. The goal of the present study was to investigate the chemical compounds, antioxidant, and antimicrobial properties of essential oil of Juniperus excelsa M. Bieb., a species of juniper with a large spread area in Turkey. Essential oils were extracted by the hydro-distillation method. The components of the hydro distilled oil samples were analyzed by gas chromatography-mass spectrometry (GC-MS). In the study, the essential oil was evaluated for its antibacterial activity against six bacterial strains consisting of two Gram (+) and four Gram (–) by the agar disc diffusion method. Additionally, the antioxidant properties of the oil were determined by TEAC/ABTS+ free radical scavenging assay. As a result, there were 27 compounds in the essential oil of J. excelsa. Of the 27 essential oil components identified, α-pinene (40.59%), α-cedrol (18.15%), β-myrcene (4.53%), and limonene (3.84%) were determined as the main components in total 91.54% of the essential oil. As a result, it was observed that the examined juniper essential oil showed a weak but effective antibacterial activity against all bacterial strains compared to the control agents, and also, the examined oil had low but valuable antioxidant activity.

Published: February 2023

The present study describes changes in fatty acid (FA) composition in Ginkgo biloba leaves subjected to senescence and to senescence induced by methyl jasmonate (MeJA). Green leaves were treated with MeJA in lanoline on the abaxial or adaxial side of the leaf blades. After three weeks of treatment, leaf blades and petioles were collected separately for FA analyses. Additionally, petioles and leaf blades were sampled for analyses before the experiment and after 6 weeks when leaf senescence was occurring. Linolenic (C18:3) and palmitic (C16:0) acids appeared to be the quantitatively most abundant FA in leaf blades and petioles of G. biloba. Both leaf senescence and that induced by MeJA caused a decrease in unsaturated FA content, especially linolenic (C18:3). However, the decrease in C18:3 acid in both leaf blades and petioles was greater when MeJA was applied to the abaxial side than when it was applied to the adaxial side of leaves or during senescence. At the same time, saturated FA content increased, resulting in a significant decrease in the ratio of total unsaturated to saturated FA. Since leaf fatty acids occur mainly as components of cell membranes, changes in their composition may have a crucial effect on membrane function and stability, as pointed out in the discussion of the results.

Published: February 2023

Purpose

This study aimed at exploring the mechanisms underlying nonalcoholic fatty liver disease (NAFLD) and developing new diagnostic biomarkers for nonalcoholic steatohepatitis (NASH).

Methods

The microarray dataset GES83452 was downloaded from the NCBI-GEO database, and the differentially expressed RNAs (DERs) were screened between the NAFLD and non-NAFLD samples of the baseline and 1-year follow-up time point group based on the Limma package.

Results

A total of 561 DERs (268 downregulated and 293 upregulated) were screened in the baseline time point group, and 1163 DERs (522 downregulated and 641 upregulated) were screened in the 1-year follow-up time point group. A total of 74 lncRNA–miRNA pairs and 523 miRNA–mRNA pairs were obtained in order to construct a lncRNA–miRNA–mRNA regulatory network. Subsequently, functional enrichment analysis revealed 28 GO and 9 KEGG pathways in the ceRNA regulatory network. LEPR and CXCL10 are involved in the Cytokine–cytokine receptor interaction (P = 1.86E-02), and the FOXO1 is involved in both the insulin signaling pathway (P = 1.79E-02) and the pathways in cancer (P = 2.87E-02).

Conclusion

LEPR, CXCL10, and FOXO1 were the characteristic target genes for NAFLD.

Published: February 2023

Maturity-onset diabetes of the young (MODY) is the most common monogenic form of diabetes, accounting for 1-2% of all diabetes cases. At least 14 different MODY subtypes have been identified the most common of which is MODY 2 caused by mutations in the glucokinase (GSK) gene. The mild hyperglycemia of MODY 2 is often first detected during pregnancy. Patients with MODY are usually misdiagnosed as either idiopathic type 1 or type 2 diabetes. The recognition of MODY 2 during pregnancy has important clinical implications as the management of hyperglycemia may differ from the established algorithm in gestational diabetes. Fetus development could be seriously affected in case it has inherited the GSK mutation and maternal hyperglycemia is insulin treated to the pregnancy adopted glycemic targets.

The case report describes the stepwise diagnostic approach to a 43-year-old woman with a history of gestational diabetes and persistent prediabetes who was found to be a carrier of a heterozygous pathogenic variant in GSK (c.184G>A) and discusses the possible genotype of her two children according to their birth weight.

Coronavirus disease (COVID-19), which is caused by SARS-CoV-2, has been announced as a global pandemic by the World Health Organization (WHO), which results in the collapsing of the healthcare systems in several countries around the globe. Machine learning (ML) methods are one of the most utilized approaches in artificial intelligence (AI) to classify COVID-19 images. However, there are many machine-learning methods used to classify COVID-19. The question is: which machine learning method is best over multi-criteria evaluation? Therefore, this research presents benchmarking of COVID-19 machine learning methods, which is recognized as a multi-criteria decision-making (MCDM) problem. In the recent century, the trend of developing different MCDM approaches has been raised based on different perspectives; however, the latest one, namely, the fuzzy decision by opinion score method that was produced in 2020, has efficiently been able to solve some existing issues that other methods could not manage to solve. because of the multiple criteria decision-making problem and because some criteria have a conflict problem. The methodology of this research was divided into two main stages. The first stage related to identifying the decision matrix used eight different ML methods on chest X-ray (CXR) images and extracted a new decision matrix so as to assess the ML methods.  The second stage related to FDOSM was utilized to solve the multiple criteria decision-making problems. The results of this research are as follows: (1) The individual benchmarking results of three decision makers are nearly identical; however, among all the used ML methods, neural networks (NN) achieved the best results. (2) The results of the benchmarking group are comparable, and the neural network machine learning method is the best among the used methods. (3) The final rank is more logical and closest to the decision-makers' opinion. (4) Significant differences among groups' scores are shown by our validation results, which indicate the authenticity of our results. Finally, this research presents many benefits, especially for hospitals and medical clinics, with a view to speeding up the diagnosis of patients suffering from COVID-19 using the best machine learning method.

An Essay on How Data Science Can Strengthen Business

Authors: Duarte Santos Antonio
Published: February 2023

Data science combines several extensions, including, e.g., statistics, scientific methods, artificial intelligence (AI) and data analysis to extract value from raw data. Analytical applications and data scientists can then verify and defer the results to discover patterns and trends. In this way, they allow business leaders to gain enlightened knowledge about the market. Companies have kept a wealth of data with them. As modern technology allowed for the creation and storage of ever-increasing amounts of information, data volumes popped. The wealth of data collected and stored by these technologies can bring regenerative benefits to organizations and societies around the world, but only if they can interpret it. That's where data science comes in. So, the applied economics refers to the application of economic theory and analysis. In this article we intend to present several software that are available for the application of economic analysis. Analysis can be performed on any type of data and is a way of looking at raw data and find useful information. There are several technologies available for economic analysis, with more or less characteristics, some of which are not only intended for this single purpose, and cover a wider spectrum of functionalities. Some of the technologies we will use are, e.g., Rstudio, SPSS, Statis and SAS/Stata. These are very common technologies when talking about economic or business analysis. The intention is to demonstrate how each of these software analyse the data and subsequently the interpretations that we can draw from that scrutiny. Organizations are using data science teams to turn data into a competitive advantage by refining products and services and cost-effective solutions. We will use some different algorithms to verify how they are processed by the different technologies, namely we will use metrics such as maximum, minimum, covariance, standard deviation, average and multicollinearity and variance, even the use of types of regression models.

The subject of the study is the characteristic of the Baroque style and the integration of its elements into the decor of the architecture of the Crimea of the Art Nouveau period. The object of the study is the architecture of the Crimea and its decor of the period of the late XIX – first third of the XX century. The research uses the methods of art criticism analysis of Baroque visual forms and their integration into modernity, the method of analysis of previous studies, the method of synthesis in conclusions regarding the connotations of Baroque symbolism. The author considers such aspects of the topic as: a general overview of the origin of the Baroque style; features of the architecture of the Crimean Art Nouveau; integration of Baroque elements into the decor of the Art Nouveau of the Crimea.     The main conclusions of the study are: 1. The appearance of the Baroque style in architecture and decor is attributed by architectural historians to the XVII century. However, its origins should be sought in the Middle Ages, since many Baroque elements repeat Arabesques brought by the Crusaders to Europe. Baroque has established itself as a church and palace style. In turn, the Asia Minor (Turkish) Baroque was a synthesis of traditional Arab elements and Western European influence in the XVIII century. 2. The Art Nouveau style in architecture and its decor is a synthesis of various elements of previous styles, arbitrarily used by architects in accordance with their personal tastes, as well as with the wishes of customers. The basis of the Crimean Art Nouveau, represented in country villas, mansions, palaces, apartment buildings, is classicism, Renaissance and Mudekhar style, with the introduction of individual features into them with the help of decor. The use of Baroque elements enlivened the buildings, giving them an elegant, southern flavor. A special contribution of the author to the study of the topic is to clarify the periodization and origin of the Baroque style. The scientific novelty of the research lies in the fact that the author for the first time analyzed the decor of the architecture of the Crimea of the modern period, identified and analyzed the elements of the Baroque, their origin and role in the style of modernity.

UMKM Kerupuk Nusa Sari merupakan perusahan yang memproduksi kerupuk, terletak di Kecamatan Cimaragas, Kabupaten Ciamis. Dalam melakukan pengadaan bahan baku, perusahaan ini membutuhkan pengendalian persediaan bahan baku yang baik dan tepat. Permasalahan yang terjadi adalah kurang efisiennya pengendalian persediaan bahan baku yang diterapkan  perusahaan. Maka dari itu penulis melakukan penelitian dengan metode EOQ untuk mengetahui total biaya persediaan terkait pengendalian persediaan bahan baku, terutama meningkatkan efisiensi biaya persediaan yang dikeluarkan perusahaan.

Jenis penelitian ini adalah deskriptif dengan menyajikan data secara kuantitatif, dengan memaparkan bagaimana pengendalian persediaan bahan baku yang diterapkan perusahaan kemudian membandingkannya dengan perhitungan menggunakan metode EOQ. Adapun data yang digunakan yaitu kebutuhan bahan baku yang terdiri dari data pembeliaan dan penggunaan bahan baku, biaya pemesanan serta biaya penyimpanan

Berdasarkan hasil analisis dengan metode EOQ dapat diketahui total kebutuhan bahan baku sebanyak 5.360 kg dengan frekuensi pembelian sebanyak 17 kali. Jumlah ini lebih kecil dibandingkan dengan kebijakan perusahaan yaitu sebanyak 5.400 kg dengan frekuensi pembelian sebanyak 48 kali pertahun. Persediaan pengaman berdasarkan metode EOQ dapat diterapkan sebanyak 56 kg. Sementara itu metode EOQ pada perusahaan harus melakukan pemesanan kembali setiap 5 hari sekali dengan persediaan maksimum sebanyak 370,96 kg. Kemudian total biaya persediaan berdasarkan kebijakan perusahaan sebesar Rp.13.157.994, sedangkan menurut metode EOQ total biaya persediaan sebesar Rp.12.506.994 pertahun. Maka dapat disimpulkan bahwa penggunaan metode  EOQ lebih efisien jika digunakan sebagai alat untuk meningkatkan efisiensi biaya persediaan dengan selisih kebutuhan bahan baku sebanyak 40 kg, selisih frekuensi pembelian sebanyak 31 kali dan selisih total biaya persediaan sebesar Rp. 651.000 pertahun.

Fueling growth and preventing stunting: the role of animal protein in achieving optimal nutrition - Indonesia's National Nutrition Day 2023 Theme
Authors: Chandra Dian Novita
Published: February 2023

Poor linear growth, currently defined as inadequate height to growth standards defined by the World Health Organization (WHO), is still a major problem in low-middle-income countries (LMICs) including Indonesia. The national survey results from 36.8% in 2007 to 30.8% in 2018 showed small differences in under-five years old children with height-for-age-Z-score less than -2 standard deviation (HAZ < -2 SD) from the growth reference or stunted.1  Though the Indonesian Nutrition Status Survey results showed an improvement in the stunting rate to 21.6% in 2022, the data revealed large regional disparities, ranging from 8% in Bali to 35.3% in East Nusa Tenggara.2  

It is known that for children with stunted growth in early life, the risk of impaired health, mortality, and delayed neurocognitive and motor development is heightened. Moreover, tend to have a long-term effect of decreased performance in education, lower productivity and socioeconomics, and a higher risk of chronic diseases in adulthood.1,3  

Stunting has many associated factors, including socioeconomic inequality, geographic differences, maternal factors, such as education, age, nutrition status, and infection; short birth intervals, low birth weight, and preterm birth, food insecurity, practices of feeding, nutrient deficiencies, such as protein, iron, zinc, calcium, and vitamins, childhood morbidity, and environmental. Low birth weight and length, unimproved sanitation, and low protein intake are the leading risk factors in developing countries, especially in the horticulture area.4,5

Background : Stature is required to calculate body mass index and determine the energy needs of patients in nutritional medical therapy. Difficulty was found to obtain stature data in patients who are unable to stand. Therefore, there are some height estimation formula to predict the actual height using knee height. This study aimed to validate the Chumlea formula on outpatient clinic of Dr. Cipto Mangunkusumo General Hospital, Indonesia.

Methods : This cross-sectional study used 90 respondents selected by consecutive sampling. Actual height, knee height, age and gender data were collected. Estimated height using the three of Chumlea formula. Pearson correlation was used to see the correlation between actual height and estimated height. Paired t-test were used to determine the difference significance.

Results : The average age of the subjects was  45±10 years old with actual height 157±10 cm, and knee height 48.8±3.5 cm. A strong positive correlation was found between actual height with all estimated height on male (p=0.000; r > 0.8) and female subjects (p=0.000; r > 0.6). However, comparison between actual height and estimated height showed no significant differences only in Chumlea L1 formula (p=0.087) and Chumlea L3 formula (p=0.824) on the male subjects.

Conclusions : Chumlea L1 and Chumlea L3 formula was a valid fomulation for calculating the estimated body height in adult male patients. There was no valid Chumlea’s formulation to estimate body height in female patients.
