STABILITAS EMOSI PELAKU PERNIKAHAN DINI DALAM MENDIDIK ANAK BALITA
Authors: Jannatunnaim Lu’ Luul
Published: February 2019

The rate of early marriage from year to year continues to increase due to economic factors, family internal factors, and social factors. Most early marriages are still middle school / high school students who do not have good emotional stability and tend to do everything they want without thinking about the impact that will occur. Many of the early marriages have children, where in educating children they unconsciously apply permissive education patterns. The personal circumstances and attitudes of each child are different, making the task of educating hard to implement, and inﬂuencing the emotional state of parents. The results showed that the emotional stability of early marriages in educating children is not good, this is because early marriages are still easily inﬂuenced by negative emotions that can be seen from the emotional response shown. Excessive emotional response is not in accordance with the notion of emotional stability, namely a permanent emotional state, not easily changed, and the response shown is not excessive. In relieving negative emotions and resolving problems that occur, early marriages more often submit to the situation assuming that emotions will be lost if left unchecked, without any effort to fnd a way out or a method of solving the problem accordingly. Although early marriages do not have good emotional stability, some early marriages have been able to maintain their emotional stability by calming themselves down and solving problems that are sources of emotion.

Published: February 2019

Background: Infections caused by E. coli cause considerable disease burden and range from frequently occurring and relatively innocent urinary tract infection (UTI) to severe bloodstream infection (BSI). The incidence of infections caused by ESBL-producing E. coli (ESBL-PEc) is increasing, justifying surveillance and development of preventive strategies in several domains. Faecal carriage is universal and believed to be the most important reservoir for E. coli from which infections can originate. It is currently unknown to what extent Dutch E. coli carriage strains in the community reflect isolates causing disease. In this study, we will perform comparative genomics to infer the population structures of human-derived ESBL-PEc from community- and hospital-acquired infections and from community-based faecal carriage samples in the Netherlands. Furthermore, we will describe the molecular epidemiology of E. coli isolates causing invasive disease (BSI). Methods: This study uses four different microbiological data sources: 1) ESBL-PEc from patients with community-acquired UTI tested in primary care between May and November 2017, 2) ESBL-PEc from urine cultures obtained from patients hospitalized between January 2014 and December 2016, 3) E. coli from blood cultures obtained from patients hospitalized between January 2014 and December 2016, and 4) ESBL-PEc from faecal samples collected in a national population- prevalence study performed between January 2014 and January 2017. Clinical epidemiological data was collected from all patients and all isolates were subjected to whole genome sequencing. Discussion: The EPIGENEC study (EPIdemiology and GENetics of E. coli) will describe the molecular epidemiology of E. coli BSI and assess the genomic population structure of ESBL-PEc strains from community-acquired and nosocomial infections, and of ESBL-PEc reflecting community-based faecal carriage. Information from these studies may assist in optimizing surveillance strategies and determining targets and potential impact of future new preventive measures.
Funding acquisition drivers for new venture firms: Diminishing value of human capital signals in early rounds of funding
Authors: Shetty Snehal , Sundaram Ranjany
Published: February 2019

Multiple factors such as human capital, amount raised in the first round, innovation etc. have an impact on the funding prospect of new ventures. This paper explored the influencing factors that drive multiple rounds of funding for new venture firms and provided a much broader perspective of funding drivers during the early stages of the new venture firm. Using signalling theory and human capital theory, this paper analyzed signals that influence the acquisition of funds in the first round and whether those signals persisted for the second and third rounds of funding when information asymmetries between the investors and new venture firms reduce. This study disentangled the signalling effects of the human capital factors across three funding rounds and proved the diminishing value of signals across each subsequent round of funding. Finding showed that the signal effect from premier institution education was the only human capital signal that persisted across each round of funding, while other signals did not persist beyond the first round of funding. In addition, new venture firms with founders educated from premier educational institutions were able to attract more investors and close more funding rounds. This study also proved that the amount raised in the first round of funding positively impacted the amounts raised in the second and third rounds stressing its importance for new venture firms. Empirical demonstration of the propositions was done with 156 new venture firms in India, the fastest growing and third largest startup ecosystem in the world.
Performance of Clustering on ANFIS for Weather Forecasting
Authors: Dewi Candra
Published: February 2019

This paper proposes the comparison of using K-Means and Fuzzy C-Means (FCM) to optimize the premise parameters on Adaptive Neuro-Fuzzy Inference System (ANFIS) for weather forecasting. The ANFIS architecture groups each of the feature inputs in the first layer into three clusters, and uses three rules for the second layer. The comparison is performed based on the RMSE value and the number of iteration. The testing is done on the percentage of 40%, 50%, and 60% of the total data. In addition, the testing is done by grouping the data based on season called rainy and dry seasons. The testing results show that both K-Means and FCM havealmost the same RMSE, except for rainy season where K-Means has better RMSE. However, K-Means requires relatively more iterations to achieve convergence. The use of FCM, in general, gives better results than K-Means. It is also shown that ANFIS provides the best performance for data onto the dry season.

Toileting skill is one of the basic self-help skills that children should master. In fact, teaching new things to children with autism is challenging. It requires a proper method to deliver the materials to these children. One of the effective learning media to teach self-help is to use visual media like video games. By using video games, children are expected to play and learn self-help skills, particularly about toileting. In addition, the video game is developed by applying certain design principles that fit with the needs of children with autism. The software is tested for its functionalities. Moreover, an implementation test is done by using observation communication analysis. Based on the results, the researchers conclude that the developed video game has implemented the proper design and materials related to toileting in accordance with the needs of children with autism. The respondents show positive results for using the video game.

An Implementation of Grouping Nodes in Wireless Sensor Network Based on Distance by Using k-Means Clustering
Authors: Azhar Rizqi Fauzil , Zainudin Ahmad , Kristalina Prima , Prakoso Bagas Mardiasyah , Tamami Niam
Published: February 2019

Wireless Sensor Network (WSN) is a network consisting of several sensor nodes that communicate with each other and work together to collect data from the surrounding environment. One of the WSN problems is the limited available power. Therefore, nodes on WSN need to communicate by using a cluster-based routing protocol. To solve this, the researchers propose a node grouping based on distance by using k-means clustering with a hardware implementation. Cluster formation and member node selection are performed based on the nearest device of the sensor node to the cluster head. The k-means algorithm utilizes Euclidean distance as the main grouping nodes parameter obtained from the conversion of the Received Signal Strength Indication (RSSI) into the distance estimation between nodes. RSSI as the parameter of nearest neighbor nodes uses lognormal shadowing channel modeling method that can be used to get the path loss exponent in an observation area. The estimated distance in the observation area has 27.9% error. The average time required for grouping is 58.54 s. Meanwhile, the average time used to retrieve coordinate data on each cluster to the database is 45.54 s. In the system, the most time-consuming process is the PAN ID change process with an average time of 14.20 s for each change of PAN ID. The grouping nodes in WSN using k-means clustering algorithm can improve the power efficiency by 6.5%.

Published: February 2019

The computer ability to detect human being by computer vision is still being improved both in accuracy or computation time. In low-lighting condition, the detection accuracy is usually low. This research uses additional information, besides RGB channels, namely a depth map that shows objects’ distance relative to the camera. This research integrates Cascade Classifier (CC) to localize the potential object, the Convolutional Neural Network (CNN) technique to identify the human and nonhuman image, and the Kalman filter technique to track human movement. For training and testing purposes, there are two kinds of RGB-D datasets used with different points of view and lighting conditions. Both datasets have been selected to remove images which contain a lot of noises and occlusions so that during the training process it will be more directed. Using these integrated techniques, detection and tracking accuracy reach 77.7%. The impact of using Kalman filter increases computation efficiency by 41%.

Process Model for the Food Service in Swiss Hospitals
Authors: Weisshaupt Oliver , Leiblein-Züger Gabriela V. , Hofer Susanne
Published: February 2019

Background

Since the introduction of Swiss Diagnosis Related Groups in 2012, a Swiss hospital's core business requires Facility Management that provides more transparent, effective and efficient services. In that respect, the new remuneration system has caused a growing interest in processes. Food provision is of high importance since it is one of the costliest support services and is a critical image factor of a hospital.

Purpose

The purpose of this research was to analyse the food service processes in Facility Management in hospitals through the lenses of social, economic and ecological sustainability as well as hygiene and safety, and to identify which issues arise from each viewpoint for the respective sub-processes.

Methodology

A two-fold qualitative case study design was applied, based on the reference model theory Process Model for Non-Medical Support Services in Hospitals. First, based on focus groups, the process model was developed. Second, the model was validated by input from interviews with Facility Management professionals.

Results

Each sub-process requires the consideration of individual factors from the perspectives of sustainability, hygiene and safety. Similarly, various overarching factors were identified, such as the production method that impact not only a single sub-process, but also play a role in the whole catering process. Additionally, it became evident that food provision in hospitals is particularly affected by the conflicting priorities of cost-effectiveness and sustainability.

Conclusion

The outcome of this work is a model that allows a holistic process analysis of catering activities in hospitals since it takes into account social, economic and ecological sustainability, as well as both hygiene and safety aspects for the individual sub-processes. This research gives guidance to facility managers who strive for process optimisation to guarantee efficient and effective food provision in hospitals.

Unique Value to the Body of Facility Management Knowledge

This work applies established catering sub-processes in hospitals to the context of sustainability, hygiene and safety. The proposed model caters to the increasing interest in processes in healthcare in Switzerland and can presumably be applied to hospitals of other countries.

Published: February 2019

Rasio elektrifikasi listrik di Nusa Tenggara Timur (NTT) hingga April 2018 baru mencapai 60,82% dari 54% pada tahun 2004. Hal ini turut disebabkan oleh beberapa daerah di Kabupaten Alor yang belum dialiri listrik. Kondisi geografis Kabupaten Alor yang tersebar menjadi beberapa pulau menyebabkan sulitnya penyediaan akses energi listrik yang terjangkau. Sementara itu, potensi arus laut di Selat Alor belum dioptimalkan. Oleh karenanya diperlukan langkah strategis untuk menyediakan akses energi listrik yang optimum dan efisien dengan memanfaatkan sumber energi terbarukan. Metode penelitian yang digunakan adalah studi pustaka. Penggunaan konsep Algoritma Prim menjadi salah satu solusi alternatif dari permasalahan tersebut. Algoritma Prim digunakan untuk menentukan saluran listrik minimum dengan menetapkan Selat Alor sebagai titik sumber dan lokasi transformator distribusi di sembilan pulau berpenghuni di Kabupaten Alor sebagai titik tujuan. Pembuatan graf disesuaikan dengan kondisi geografis Kabupaten Alor dan setiap sisi memiliki bobot yang berupa hasil kali antara jarak dari kedua lokasi transformator dan biaya kabel yang akan digunakan. Berdasarkan graf tersebut ditentukan minimum spanning tree dengan mendaftar sisi-sisi di graf dari sisi terpendek. Hasil yang diperoleh berupa pemasangan kabel sebesar 12,282 triliun rupiah dengan panjang kabel sebesar 345,3 km. Hal ini menunjukkan bahwa “PRIMATHRIC” sebagai penerapan dari matematika, khususnya Algoritme Prim mampu menjadi inovasi baru dalam menciptakan akses energi yang terjangkau dan merupakan salah satu tujuan pembangunan berkelanjutan 2020.

Authors: Mulawarman , , Sastrosumarto Setyono , Na'iem Mohammad
Published: February 2019

A controlled crossing experiment using a factorial mating design, involving female parents of E. pellita and male parents of E. urophyla that randomly sampled from the breeding population of both species, was conducted to assess the degree of genetic control on interspecific crossability for hybrid between E. pellita and E. urophylla. As measures of crossability, number of seeds per capsule and percentage of germinated seed were determined for each individual cross. The effect of female, male and female × male was significant on number of seed per capsule and percentage of germination. There was a slight tendency that the family produced more viable seed might produce less viable seed. Additive and dominance genetic varians were estimated as measures of the genetic control. The dominance variance had the major contribution to the genetic control of seed production and seed germination. Female source of variation has the major contribution to the additive genetic influence. Therefore, to maximize the production of viable seed, parent trees with desired traits should be selected on specific cross basis.

The fish was weighed every other week, i.e., at week 0, 2, 4, 6, and 8. The fish in each cage were gathered to one side of the cage with bamboo sheets. Thirty fish for each of three colors (blue, green, and red) were randomly sampled from each cage using a scoop net. The result showed that the green fish was the fastest growing in 2 of the 3 significant cases and blue for 1 case. In most cases color morphs also did not show any differences in the weight regression coefficients. However, there were 5 significant cases where green was always the best followed by the blue one. Thus, there was evidence that the dark color (green and blue) gained weight faster than light one (red). Green and blue colored showed similarity in growth performance based on weight regression coefficient.

Improvement of high yield maize cultivars possessing high quality of seed as showed by high lysine and tryptophan content must be fulfilled with resistance against downy mildew pathogen in any maize breeding program. A set of experiment to study genetic variability and to estimate both heritability and heterosis of important characters of grain yield on DMR and QPM lines has been conducted. Four downy mildew resistance (DMR) lines, i.e. Nei 9008, P 345, Ki 3, and MR 10; three quality protein maize (QPM) lines, including CML 161, CML 163, and CML 172; and their single cross hybrids formed based on line × tester mating design were used in the experiment. The following characters: height of the first ear, seeds number per row, seed weight per ear, and grain yield per plot showed broad genetic variability. Narrow sense heritability (hns) of grain yield and its components ranged from 0.01 to 0.71. Broad sense heritability (hbs), on the other hand, ranged from 0.20 to 0.74. It was found that hybrid derived from crossing between parental inbred lines possessing broad genetic background would express high heterosis.

Thirty-two TWC QPM hybrids were selected based on genotype × environment (G × E) interaction and stability. The experiment was conducted in three locations with differing conditions. TWC QPM hybrids were tested under nitrogen deficient and nitrogen sufficient fertilization at the Padjadjaran University Faculty of Agriculture Experimental Station, Jatinangor, Sumedang from March until July 2004. Another set of TWC QPM hybrids was tested under sufficient nitrogen fertilization at a high altitude location in Pangalengan from June until October 2004. Each experiment was arranged in a randomized block design with two replications with 32 TWC QPM hybrids and two check cultivars, i.e. Bisi-2 and Pioneer-7. Bartlett’s homogeneity test was applied to error derived from analyses of variances of every location. Combined analysis was done since error was homogenous for all observed characters. The combined analysis showed that there was G × E interaction for seed weight per 10 plants. Preliminary METs in West Java successfully selected newly developed TWC QPM hybrids based on stability and interaction between G × E. These hybrids are QPDMR-8-BCP1 and QPDMR-8-BCP2 for wide adaptive cultivars and QPDMR-35-BCP1, QPDMR-26-BCP1, QPDMR-8-BCP1, QPDMR-1-BCP2, QPDMR-8-BCP2, QPDMR-10-BCP2 and QPDMR-15-BCP2 specific adaptive cultivars.
Gene Transfer to Rice Mediated by Agrobacterium tumefaciens: Transient Expression of sgfp in Rice Calluses of indica cv. Fatmawati and japonica cv. Nipponbare
Authors: Yoshida Tomohiko , Carsono Nono
Published: February 2019

Transient expression of synthetic green fluorescent protein (sgfp) mediated by Agrobacterium is rapid and useful approach for visual monitoring the genetic transformation event in transformed cells/tissues of examined genotype. The significant differences in transient expression of two genotypes (indica cv. Fatmawati and japonica cv. Nipponbare) were found with regard to the osmotic treatment (0.4 M mannitol), solid subcultured callus, and 10 min. air drying. While, no significant differences in sgfp expression were observed in two genotypes on without air-drying and 5 min. air-drying of calluses prior immersed in Agrobacterium suspension. Surprisingly, the sgfp expression could not be detected in suspension-subcultured callus of both cultivars. The highest sgfp expression was achieved in Nipponbare callus treated with 10 min. air drying. The level of green fluorescent spots was higher in Nipponbare than that in Fatmawati, however, plants regenerated from Fatmawati were considerably comparable with those of Nipponbare. Seventeen and 16 putative transgenic rice plants expressing sgfp transgene were obtained from Nipponbare and Fatmawati, respectively.

ACDP (Analytical and Capacity Development Partnership) data suggests that 10% of teachers did not attend school and 14% of those attending did not attend the class. This number indicates the teacher is not satisfied with their work. Teacher job satisfaction needs to be improved so that education can run better. Teachers who are satisfied at work will feel happy with their work, happy with the work environment and so on. Unsatisfied teachers can cause low performance and even increase the desire to move or stop working. Therefore, efforts need to be made to optimize teacher work satisfaction. Two ways that can be done to improve teacher job satisfaction are by giving appropriate rewards and increasing motivation.
