Support Vector Regression Based S-transform for Prediction of Single and Multiple Power Quality Disturbances

This paper presents a novel approach using Support Vector Regression (SVR) based S-transform to predict the classes of single and multiple power quality disturbances in a three-phase industrial power system. Most of the power quality disturbances recorded in an industrial power system are non-stationary and comprise of multiple power quality disturbances that coexist together for only a short duration in time due to the contribution of the network impedances and types of customers’ connected loads. The ability to detect and predict all the types of power quality disturbances encrypted in a voltage signal is vital in the analyses on the causes of the power quality disturbances and in the identification of incipient fault in the networks. In this paper, the performances of two types of SVR based S-transform, the non-linear radial basis function (RBF) SVR based S-transform and the multilayer perceptron (MLP) SVR based S-transform, were compared for their abilities in making prediction for the classes of single and multiple power quality disturbances. The results for the analyses of 651 numbers of single and multiple voltage disturbances gave prediction accuracies of 86.1% (MLP SVR) and 93.9% (RBF SVR) respectively.

Utilization of Scientific Publication Media to Improve the Quality of Scientific Work

The publication of scientific work is an absolute thing that must be owned and produced by academics at this time. Moreover, when referring to the Minister of Administrative and Bureaucratic Reform (PAN RB) Regulation No. 17 of 2013 and the Minister of Education and Culture Regulation No. 92 of 2004 which states that the increase in the academic level of lecturers requires publication of accredited national scientific journals and journals Internationally reputable in their field. In addition to being very important for the performance of lecturers, the publication of scientific papers has become a government regulation through the Director General of Higher Education, which requires S1, S2 and S3 students to make a summary of scientific work published both online and in print as one of the graduation requirements. Seeing this, Raharja College has participated in providing publication media for scientific works, especially in online forms, one of which is iLearning Journal Center (iJC). Until now iLearning Journal Center has overseen 5 (five) journals in it with different scope of research. However, the problems that occur at this time are still a lack of the general public to know especially in the Higher Education environment regarding the iLearning Journal Center (iJC) as a publication media for online scientific work. In this study will be discussed about the steps or methods taken to maximize the use of iLearning Journal Center (iJC) as an online journal publication media to improve the quality and quantity of scientific works. This study uses SWOT analysis method and system design using the Unified Modeling Language (UML) and the applications used in this study by applying the Open Journal System (OJS) which is known as management software and publishing online journals. The results of this study are a governance or management that can be done as a step to maximize the increase of publication of online scientific works for the academic community.

Application of Copper Fungicide and Row Covers to Control Phytophthora Seedling Blight Disease on Cocoa

Phytophthora seedling blight disease is one of the important diseases in cocoa. The disease is caused by the fungus of Phytophthora palmivora belongs to class Oomycetes. The aim of this research was to determine the effectiveness of the use of row covers and copper oxide fungicide applications to control seedling blight Phytophthora. Covering treatment was to place cocoa seedlings inside bamboo frame covered by transparent plastic in order to avoid from rainfall effect. The research was conducted in the Kaliwining Experimental Station at Indonesian Coffee and Cocoa Research Institute (ICCRI). Experiments were carried out four treatments and repeated 6 times. Each treatment consists of 100 seedlings planted in polybags and placed in the nursery area with a protective paranet. The treatment consisted of (1) row covers, (2) spraying of copper oxide 0.2%, (3) a combination of row covers and copper oxide 0.2% and (4) control (no covers and spray). Observations made 7 days after treatment with an interval of 7 days for 10 weeks. The results showed that row covers able to prolong the incubation period of the disease for 14 days, while the application of row covers + copper oxide 0.2% was able to save cocoa seedlings by 96.2%

Pengaruh Terapi Spiritual Emotional Freedom Technique (SEFT) Terhadap Tekanan Darah Penderita Hipertensi

SEFT termasuk teknik relaksasi yang penggabungan teknik sistem tubuh dan terapi spiritual menggunakan menekan pada titik-titik tertentu pada tubuh. SEFT bantuan individu bebas dari tekanan emosional (energi negatif), yang merupakan penyebab meningkatnya tekanan darah pada pasien dengan hipertensi. Penelitian ini bertujuan untuk menganalisis pengaruh spiritual teknik kebebasan emosional (SEFT) terhadap tekanan darah pada pasien hipertensi. Penelitian ini menggunakan pendekatan kuantitatif dengan metode kuasi-eksperimen dan desain kelompok kontrol non-eqiuvalent. Populasi dalam penelitian ini adalah semua dengan hipertensi sebanyak 148 orang. Teknik sampling yang digunakan purposive sampling. Ada 30 responden sebagai sampel dibagi menjadi dua kelompok: 15 responden sebagai kelompok intervensi dan 15 responden sebagai kelompok kontrol. Instrumen data yang digunakan sphygmomanometer merkuri, stetoskop dan lembar observasi. Hasil analisis dengan menggunakan t-test independen menemukan bahwa nilai p 0,000 (sistole) dan nilai p dari 0,019 (diastole), maka dapat disimpulkan bahwa terdapat perbedaan bermakna sebelum dan setelah terapi SEFT. Terapi spiritual teknik kebebasan emosional (SEFT) dapat digunakan sebagai pengobatan alternatif yang tepat dan praktis pada pasien hipertensi

Dampak Sosial Pembangunan Jembatan Desa Kampung Panjang Airtiris Kecamatan Kampar Utara Kabupaten Kampar

Bridge infrastructure development coined positive impact and negative impact in the lives of the viage Kampung Panjang, the perceived impact the community with the construction of the bridge can be in many different forms. this study to determine the positive and negative impacts of development experienced by rural village kampung panjang, and, knowing the social impact of the construction of the bridge to changes in social status vertically and determine changes in social status due to the construction of a bridge or there are other factors.
