Authors: Sugidamayatno Silvano , Lelono Danang
Published: February 2020

Threats or fraud for credit card owners and banks as service providers have been harmed by the actions of perpetrators of credit card thieves. All transaction data are stored in the bank's database, but are limited in information and cannot be used as a knowledge. Knowledge built with credit card transaction data can be used as an early warning by the bank. The outlier analysis method is used to build the knowledge with a local outlier factor algorithm that has high accuracy, recall, and precision results and can be used in multivariate data. Testing uses a matrix sample and confusion method with attributes date, categories, numbers, and countries. The test results using 1803 transaction data from five customers, indicating that the average value accuracy of LOF algorithms (96%), higher than the average accuracy values of the INFLO and AFV algorithms (84% and 77%).
Modification of Stemming Algorithm Using A Non Deterministic Approach To Indonesian Text
Authors: Rifai Wafda , Winarko Edi
Published: February 2020

Natural Language Processing is part of Artificial Intelegence that focus on language processing. One of stage in Natural Language Processing is Preprocessing. Preprocessing is the stage to prepare data before it is processed. There are many types of proccess in preprocessing, one of them is stemming. Stemming is process to find the root word from regular word. Errors when determining root words can cause misinformation. In addition, stemming process does not always produce one root word because there are several words in Indonesian that have two possibilities as root word or affixes word, e.g.the word “beruang”.To handle these problems, this study proposes a stemmer with more accurate word results by employing a non deterministic algorithm which gives more than one word candidate result. All rules are checked and the word results are kept in a candidate list. In case there are several word candidates were found, then one result will be chosen.This stemmer has been tested to 15.934 word and results in an accurate level of 93%. Therefore the stemmer can be used to detect words with more than one root word.

Authors: Siregar Alda Cendekia , Octariadi Barry Ceasar
Published: February 2020

Traditional fabric is a cultural heritage that has to be preserved. Kain Lunggi is Sambas traditional fabric that saw a decline in its crafter. To introduce Kain Lunggi in a broader national and global society in order to preserve it, a digital image processing based system to perform Kain Lunggi pattern recognition need to be built. Feature extraction is an important part of digital image processing. The visual feature that does not represent the character of an object will affect the accuracy of a recognition system. The purposes of this research are to perform feature selection on sets of feature to determine the best feature that can increase recognition accuracy. This research conducted in several steps which are image acquisition of Kain Lunggi pattern, preprocessing to reduce image noise, feature extraction to obtain image features, and feature selection. GLCM is implemented as a feature extraction method.  Feature extraction result will be used in a feature selection process using CFS (Correlation-based Feature Selection) methods. Selected features from CFS process are Angular Second Moment, Contrast, and Correlation. Selected features evaluation is conducted by calculating classification accuracy with the KNN method. Classification accuracy prior to feature extraction is 85.18% with K values K=1 ; meanwhile, the accuracy increases to 88.89% after feature selection. The highest accuracy improvement of 20.74% in KNN occurred when using K value K= 4.

Authors: Habibi Muhammad , Cahyo Puji Winar
Published: February 2020

Instagram is a social media that has the potential to be used to increase awareness of a product. Approximately 70% of users spend their time searching for a product on Instagram. Many people promote their products with a lack of attention to the target. So that not infrequently the information distributed is inaccurate information and not following user characteristics. This study aims to cluster the characteristics of Instagram users based on hashtag compatibility. The method used in this study is the K-Means Clustering method. Based on the results of the experiment, this research succeeded in clustering Instagram users based on the hashtag match on the text caption. Besides, TF-IDF can be used as a feature suitable for the K-Means Klastering method. The results of the hashtag "#kopi" analysis resulted in hashtag suggestions that can be used for the promotion of a product related to coffee, including the hashtag #coffeeshop and #coffee with total usage of 14968 captions.
Agent-based Truck Appointment System for Containers Pick-up Time Negotiation
Authors: Ramadhan Fakhri Ihsan , Wasesa Meditya
Published: February 2020

Congestion in the seaports area is a common issue in many parts of the world. Fluctuating truck arrival has been identified as one of the significant determinants of congestion. In response, a truck appointment system (TAS) is introduced to manage truck arrival, particularly at peak times. In the existing TAS mechanism, the scheduling decision is centralized and disregards the concerns of trucking companies. Moreover, TAS may complicate the business operation of trucking companies that already have a constrained truck schedule. This study proposes a decentralized negotiation mechanism in TAS that allows trucking companies to adjust arrival times by utilizing the waiting time estimation provided by the terminal operator. We develop an agent-based model of a TAS in the container terminal pick-up procedure. The simulation results indicate that compared to the existing TAS mechanism, the negotiation TAS mechanism generates a shorter average truck turnaround time regardless of truck arrival rates. In terms of average net time cost, the negotiation TAS mechanism provides better value under high truck arrival rate conditions. The incentive for trucking companies to participate in the negotiations is even higher at peak times.

Authors: Guterres Lilia Ervina Jeronimo , Ashari Ahmad
Published: February 2020

The current technology is changing rapidly, with the significant growth of the internet technology, cyber threats are becoming challenging for IT professionals in the companies and organisations to guard their system. Especially when all the hacking tools and instructions are freely available on the Internet for beginners to learn how to hack such as stealing data and information. Tic Timor IP is one of the organisations involved and engaged in the data center operation. It often gets attacks from the outside networks. A network traffic monitoring system is fundamental to detect any unknown activities happening within a network. Port scanning is one of the first methods commonly used to attack a network by utilizing several free applications such as Angry IP Scan, Nmap and Low Orbit Ion Cannon (LOIC).  On the other hand, the snort-based Intrusion Detection System (IDS) can be used to detect such attacks that occur within the network perimeter including on the web server. Based on the research result, snort has the ability to detect various types of attack including port scanning attacks and multiple snort rules can be accurately set to protect the network from any unknown threats.

El álgebra de la estequiometria
Authors: García García José Luís
Published: February 2020

La estequiometria es uno de los conceptos más importantes, y también más difíciles de la química. En este artículo planteamos un mecanismo alternativo de entender la estequiometria en términos de soluciones generales, que no implican necesariamente situaciones numéricas, con base a una interpretación algebraica del número de Avogadro. Este método permite separar el análisis químico de una situación estequiométrica de una solución numérica particular, de manera tal que se ahorran esfuerzos al resolver situaciones concretas, ya sea a la hora de afrontar ejercicios de lápiz y papel teóricos o de afrontar situaciones experimentales donde debemos calcular réplicas de una situación. Por medio de la solución numérica y la demostración basada en el número de Avogadro determinamos que es una metodología igual de adecuada para resolver problemas de estequiometria, por lo que se deja la puerta abierta para un estudio de campo comparativo entre este método analítico y el método de factores de conversión clásico.

Program Keluarga Harapan dan Penurunan Angka Kematian Ibu (Studi di Provinsi Jambi dan Provinsi Kalimantan Selatan)
Authors: Susiana Sali
Published: February 2020

The study was conducted with a qualitative approach to see how the Family Hope Program (PKH) played a role in decreasing Maternal Mortality Rate (MMR) in Jambi and South Kalimantan Provinces. Data were obtained from interviews with PKH management officials, PKH assistants and PKH recipients who were pregnant. It was found that there was no direct connection between PKH and the decline in MMR, because there was no detailed provision regarding the percentage of cash received from PKH that had to be spent to improve the nutritional quality of PKH recipients, thus influencing the quality of maternal health and reducing MMR. In addition, not all pregnant women check themselves at a minimum of 4 times during pregnancy. The two provinces do not hold special programs for pregnant women receiving PKH. Nevertheless, there were several efforts to improve the quality of health and nutrition of pregnant women from the Ministry of Health, namely through the provision of blood tablets and biscuits, as well as the implementation of the Class for Pregnant Women. To increase the effectiveness of PKH in reducing MMR, it is necessary to periodically provide assistance and monitoring to PKH recipients who were pregnant.Penelitian dilakukan dengan pendekatan kualitatif untuk melihat bagaimana peran Program Keluarga Harapan (PKH) dalam penurunan Angka Kematian Ibu (AKI) di  Provinsi Jambi dan Kalimantan Selatan. Data diperoleh dari wawancara kepada pejabat pengelola PKH, pendamping PKH dan ibu hamil penerima PKH. Ditemukan bahwa tidak terdapat kaitan secara langsung antara PKH dan penurunan AKI, karena tidak ada ketentuan yang rinci mengenai persentase uang tunai yang diterima dari PKH yang harus dibelanjakan untuk meningkatkan kualitas gizi ibu hamil penerima PKH, sehingga berpengaruh pada kualitas kesehatan ibu hamil dan penurunan AKI. Selain itu, tidak semua ibu hamil  memeriksakan diri minimal 4 kali selama kehamilan. Kedua provinsi tidak menyelenggarakan  program khusus bagi ibu hamil penerima PKH. Meskipun demikian,  ada beberapa upaya untuk meningkatkan kualitas kesehatan dan gizi ibu hamil yang menjadi program Kementerian Kesehatan, yaitu melalui pemberian tablet tambah darah dan biskuit, serta penyelenggaraan Kelas Ibu Hamil. Untuk meningkatkan efektivitas PKH dalam menurunkan AKI, perlu dilakukan pendampingan dan monitoring secara berkala kepada ibu hamil penerima PKH.

Published: February 2020

This review summarizes current knowledge concerning the isolation, structural
elucidation, biological/pharmacological activities, and total synthesis of
halogen-containing secondary metabolites isolated from ascidians of the
family Didemnidae. Overall, 81 compounds are presented, displaying great
structural diversity and possessing a number of significant
biological/pharmacological properties. In addition to the most numerous
brominated compounds, chlorinated and iodinated ones were also found. The
most prolific genus in regard to the number of published papers and isolated
molecules is the genus Didemnum, which was treated separately from the rest
of the genera of the ascidian family. The structural complexity of the
isolated metabolites prompted a number of synthetic endeavors that not only
provided conclusive proof of the structure of the metabolites but also
enabled the biological tests and the possible application of these
metabolites.

Published: February 2020

The paper presents the unsteady numerical simulation results of tip leakage flow in high pressure steam turbines, and also presents the influence analysis of leakage vortexes on pressure fluctuation characteristics of rotor cascade under different blade tip seal clearances. The numerical method for calculating is based on the large eddy simulation turbulence model and the pressure fluctuation of rotor cascade which induced by the unstable leakage vortexes is obtained by frequency spectrum analysis. The results show that the vortex frequencies in tip seal cavity contain both the wheel rotating frequency and the high frequency caused by the tip leakage flow breaking into small scale vortexes. The unsteady characteristics of tip leakage flow also induce steam exciting force which changes with the time.

In the digital era, the child environment is faced with technology that can influence child development. The aims of this research were to analyze the influence of child and family characteristics, gadget usage, and mother-child interaction on social-emotional development among preschool children. The research involved 122 families of preschool and selected randomly. The research location was chosen purposively that is Kedung Badak Village, Tanah Sareal Sub-district, Bogor City. Data was collected through interviews with questionnaires and then analyzed by descriptive and multiple linear regression test. The gadget usage consists of the duration of child’s gadget usage, child’s gadget addiction, and parental control. The results of multiple linear regression test shows that increasing the level of child's gadget addiction can decrease social-emotional development, whereas the increasing mother-child interaction can increase social-emotional development. Meanwhile, child age and family size positively influence social-emotional development but mother's education negatively affects social-emotional development. So, parents should strive for children not to use gadgets too often and to provide more opportunities for children to play and socialize. The government is also expected can educate parents about parenting in the digital age especially for early childhood parenting.

Background:

It is well known that psychotic symptoms can occur as a result of seizure activity in the brain. This can easily be diagnosed in those with recognizable seizures by taking a careful history. However, in the absence of a typical seizure presentation, it is far more challenging to differentiate between an organic and primary psychosis.

Case Presentation:

We present the case of a 51-year-old female who had a 28-year history of treatment-resistant schizophrenia. She did not report or display any seizure activity, and an extensive investigation was unremarkable. The unusual nature of her psychopathology, which was predominantly visual hallucinations and somatic delusions, and the difficult to treat nature of her symptoms, prompted investigation with Electroencephalograph which demonstrated bilateral temporal lobe epileptic activity.

Conclusion:

Treatment with divalproex sodium and discontinuation of antipsychotic medication achieved an excellent response, where her visual hallucinations and somatic delusions were both remarkably ameliorated.

Cipta Kridatama merupakan anak perusahaan dari PT. ABM Investama Tbk yang bergerak sebagai perusahaan kontraktor pertambangan pada area IUPOP (Izin Usaha Penambangan Operasi Produksi) milik PT. Trisensa Mineral Utama. PT. Cipta Kridatama melakukan aktivitas pengupasan lapisan tanah penutup pada luas wilayah ± 3.414 ha. Proses kegiatan pengupasan tanah penutup sering sekali terjadi ketidaksesuaian hasil produksi aktual di lapangan dengan target yang direncanakan. Salah satu kendala yaitu material lumpur yang menutupi seam target dari Pit 5B21. Produksi perusahaan pada bulan Desember yang direncanakan yaitu sebesar 895.000 BCM. Masalah pemindahan material lumpur menyebabkan produksi aktual tanah penutup pada bulan Desember hanya sebesar 845.262 BCM dan tidak sesuai yang direncanakan oleh perusahaan. Fleet pemindahan material lumpur (mud) pada Pit 5B21 terdiri dari 1 (satu) unit excavator tipe 349DL, 8 (delapan) unit Off Highway Truck tipe 773, 1 (satu) unit bulldozer tipe D9R, dan 1 (satu) unit grader tipe 14M. Tujuan penelitian ini adalah menghitung biaya pemindahan lumpur dan volume tanah penutup yang harus dikupas agar memeroleh laba untuk menutupi biaya pemindahan lumpur tersebut. Analisis titik impas adalah solusi alternatif yang dapat digunakan untuk mengetahui laba yang diperoleh dari pemindahan material tanah penutup yang dapat menutupi biaya pemindahan material lumpur. Data yang digunakan dalam penelitian ini yaitu data biaya bahan bakar, biaya opeasi dan biaya kepemilikan bulan Desember 2017. Hasil analisis menunjukkan bahwa volume tanah penutup yang dapat menghasilkan pendapatan untuk kesetimbangan biaya pemindahan lumpur sebesar US$ 47,109 adalah 238.130 BCM.

Published: February 2020

Institutional learning outcomes indicate the knowledge and skills that all students regardless of disciplines from a specific university demonstrate. This paper shared experience from a case study to conduct assessment of institutional learning outcomes (general education program) from a U.S. comprehensive university. The paper discussed the achievements it has made for the past two year such as two-year assessment timeline to collect data, use of a national Valid Assessment of Learning in Undergraduate Education (VALUE) rubric to assess students’ performance, the use of technology in data analysis, and the best practices to communicate assessment results to multiple stakeholders to facilitate the decision making; the challenges encountered such as technology, faculty interpretation of the VALUE rubric, the participation rate, infrastructure for faculty engagement and reliability of data collection; and improvement plans. Researcher also made some recommendations for Vietnam HEIs to implement the assessment process for both quality improvement and accountability purposes.

Objective:

The liver is a key metabolic organ involved in lipid metabolism and maintenance of cholesterol homeostasis in the body. However, hypercholesterolemia and oxidative stress is associated with the fatty liver which is the major risk factor associated with cardiovascular diseases (CVDs). The objective of this study was to investigate the hypolipidemic property of N-acetylcysteine (NAC) in dexamethasone-induced hyperlipidemic rats.

Materials and Methods:

Dexamethasone (10 mg/kg) was administered on alternate days intraperitoneally for 28 days to induce hyperlipidemia. NAC (50 mg/kg and 100 mg/kg) was daily administered intraperitoneally for 28 days. After 24 h of the last treatment blood and liver samples were collected.

Results:

The relative body and liver weights, activities of serum alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, lipid profile, and antioxidant defense markers were measured. The result indicated that the treatment of hyperlipidemic rats with 50 and 100 mg/kg NAC significantly (P < 0.05) prevented dexamethasone-induced body weight loss and restored liver weight. In addition, NAC reduced the elevation of hepatic enzymes activities induced by dexamethasone. Moreover, NAC exhibits hypolipidemic effect as demonstrated by reversal of serum levels of total cholesterol, triacylglycerol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and atherogenic index.

Conclusion:

These findings indicated that NAC was able to restore dyslipidemia induced by dexamethasone through improving liver function parameters and augments antioxidant defense systems. Altogether the anti- hyperlipidemic effects exhibited by NAC might have been mediated partly through antioxidant actions and could be beneficial against CVDs.
Microbial and some heavy metals analysis of smoked fishes sold in urban and rural markets in Akwa Ibom State, Nigeria

Objective:

The unhygienic nature of our local markets, including fish handlers, may contribute to the presence of microorganisms in smoked fish leading to food poisoning. Furthermore, heavy metals can find their way into the food chain through fish raising public health concerns. This study assessed the microbial load and some heavy metals in smoked fishes (bongafish and catfish) sold in urban and rural markets in Akwa Ibom State, Nigeria.

Materials and Methods:

Standard microbiological techniques and analytical procedures were used for microbial and heavy metals analyses, respectively.

Results:

The results revealed that all the smoked fish obtained from the two markets were contaminated with heavy metals and microorganisms. Zinc was the most frequently detected heavy metal in both fish types (catfish: 15.50 ± 9.99 mg/kg; and bongafish: 16.40 ± 12.28 mg/kg) obtained from urban market, while in the rural market, it was cadmium (catfish: 15.95 ± 10.15 mg/kg; and bongafish: 18.25 ± 7.15 mg/kg). The overall elemental concentrations of the heavy metals in the fishes were in decreasing order of Cadmium>Zinc>Nickel>Cobalt>Lead. The most predominant bacterial species in fishes from the urban market was Bacillus subtilis (7.5 × 104 ± 0.871 colony- forming unit/g) while Candida tropicalis (9.2 × 104 ± 0.105) was the most predominant fungal species. More bacteria and fungi were encountered in fishes from the rural market than from the urban market. The differences in the microbial loads from the two markets were not statistically significant (P > 0.05).

Conclusion:

There is a potential health risk of eating smoked fishes that are poorly stored or handled in the market as a result of heavy metal contamination and the presence of the pathogenic organism. Therefore, maintenance and enforcement of adequate sanitation practices in these markets should be encouraged to avert unpleasant health consequences.

Published: February 2020

The potential to predict Solvation Free Energies (SFEs) in any solvent using a machine learning (ML) model based on thermodynamic output, extracted from 3D-RISM simulations in water is investigated. The models on multiple solvents take into account both the solute and solvent description and offer the possibility to predict SFEs of any solute in any solvent with root mean squared errors less than 1 kcal/mol. Validations that involve exclusion of fractions or clusters of the solutes or solvents exemplify the model’s capability to predict SFEs of novel solutes and solvents with diverse chemical profiles. In addition to being predictive, our models can identify the solute and solvent features that influence SFE predictions. Furthermore, using 3D-RISM hydration thermodynamic output to predict SFEs in any organic solvent reduces the need to run 3D-RISM simulations in all these solvents. Altogether, our multi-solvent models for SFE predictions that take advantage of the solvation effects are expected to have an impact in the property prediction space.
