Authors: T Muh. Yusuf , Sultan Ahmad Rizal , Thaha Sarma 
Published: May 2020

Salah satu permasalahan yang umumnya terjadi dalam proses penyaluran energi listrik yaitu rendahnya faktor daya pada sistem khususnya jika digunakan pada tingkat industri, Industri pada umumnya rata-rata menggunakan beban yang bersifat induktif sehingga dalam penerapannya diperlukan daya reaktif sebagai suplay beban induktif untuk memenuhi kebutuhan pada sistem jaringan distribusi tenaga listrik. Faktor daya rendah dapat mengakibatkan kualitas daya terganggu, kualitas daya yang buruk maka akan berdampak mempengaruhi sistem secara keseluruhan dan dapat merusak peralatan maupun sistem tersebut, Sementara kualitas daya yang baik dapat mengoptimalkan kinerja system jaringan distribusi,peralatan dan beban yang terpasang. Penelitian ini bertujuan untuk memperbaiki kualitas daya pada sistem instalasi tenaga dengan mengambil parameter yang dijadikan sebagai rujukan yaitu nilai faktor daya pada system. Adapun standar parameter sesuaidengan standar yang ditetapkan oleh PUIL dan IEEE. Dalam perbaikan faktor daya terdapat beberapa metode yang dapat digunakan yaitu metode Individual kompensasi, Grup kompensasi, Global kompensasi. Dari beberapa hasil tersebut dapat disimpulkan bahwa untuk perbaikan faktor daya yang efisien dalam penyaluran daya reaktif maka digunakan kompensator dengan metode individual kompensasi. Ketiga metode diatas dapat dibuktikan dengan menggunakan salah metode simulasi di aplikasi ETAP.

Published: May 2020

Transformator berfungsi menyalurkan tenaga listrik dengan cara menaikkan atau menurunkan tegangan kemudian menyalurkan dari dari suatu rangkaian listirik ke rangkaian listrik lainnya. Transformator didesain dengan suhu sekitar 20 tetapi beroperasi pada suhu lingkungan 30 di Indonesia, maka transformator tersebut harus disesuaikan pembebanannya. Semakin tinggi suhu setempat semakin pendek operasional dan semakin besar susut umur dari transformator tersebut.. Pemanasan pada belitan trafo dapat mengkibatkan isolasi menjadi rusak dan kenaikan temperatur minyak akan mengubah sifat serta komposisi minyak trafo. Apabila perubahan-perubahan tersebut dibiarkan akan mengakibatkan nilai isolasi dari minyak menurun. suhu belitan pada sebuah transformator dapat dipengaruhi oleh besarnya beban serta temperatur lingkungan. Perlu dianalisis nilai suhu belitan pada sebuah transformator berdasarkan standar IEC354 yang diterapkan yaitu maksimal 98ºC.Pada tulisan ini meneliti pengaruh beban puncak terhadap susut umur transformator di PT.PLN (Persero) Rayon Daya. Hasil penelitian diperoleh pembebanan tranformator PT.IBT.007 dan transformator PT.IBT.SPTC masing-masing 90.3 % dan 91.5% . susut umur yang didapatkan sebesar 122% dan 136% sehingga sisa umur transformator diperkirakan 15 tahun dan 12 tahun.

Impacts of Sunnhemp and Piegon Pea on Plant-Parasitic Nematodes, Radopholus similis and Meloidogyne spp., and Beneficial Bacterivorous Nematodes
Authors: Henmi Valerie H. , Marahatta Sharadchandra P. 
Published: May 2020

Plant-parasitic nematodes such as burrowing nematode (Radopholus similis) and root-knot nematode (Meloidogyne spp.) are dominant in the banana, Musa spp., ecosystem. Beneficial nematodes such as bacterivores are also found in banana fields. A tropical cover crop, sunn hemp (Crotalaria juncea) (SH), can be used to suppress plant-parasitic nematodes and enhance beneficial bacterivorous nematodes. However, SH cultivation in Hawaii is under the threat of the flour beetle. Thus, two experiments: Trial-I and Trial-II were conducted to compare the effects of another tropical cover crop, pigeon pea (Cajanus cajan) (PP) with SH and no-cover crop control (CC) on R. similis and Meloidogyne spp. suppression and beneficial bacterivorous nematodes enhancement. In both experiments soils infested with R. similis and Meloidogyne were sampled and amended with cover crop treatments (SH or PP) or CC and kept for two weeks. At the end of each experiment, nematodes were extracted through the Baermann funnel technique. The results of Trial-I and Trial- II showed that SH and PP did not reduce R. similis number (P > 0.05). However, Meloidogyne numbers were reduced by SH and PP in Trial-I (P < 0.05). In Trial II, Meloidogyne was not found in SH and PP. In both experiments, SH consistently increased beneficial bacterivorous nematodes number (P < 0.05). Cover crop PP increased beneficial bacterivorous nematode numbers in Trial -I (P < 0.05), but not in Trial –II (P > 0.05). However, the trends associated with the numbers of beneficial nematodes were consistently higher in PP compared to CC. Farmers could choose PP as an alternate to SH, as a cover crop for Meloidogyne suppression and beneficial nematode enhancement.

Published: May 2020

Root knot nematodes (Meloidogyne species) are major pests of vegetable crops causing serious losses in quantity and quality of crop yield. This study involves an assessment of their suitable hosts on the basis of variations in their population densities and body sizes in different vegetable crop plants under field conditions. A random survey of root knot nematode infestation in vegetable crops was conducted in 9 villages of Abhanpur block, Chhattisgarh state, Central India, from January 2012 to March 2012. Diseased plants were identified on the basis of above ground symptoms and soil and root samples collected by digging. Extraction of nematodes was done by Cobb’s sieving and decantation method and Baerman’s funnel technique. Identification was done microscopically by morphological examination of perineal patterns of female nematodes. Body sizes were measured by using an eyepiece/ocular micrometer. Twenty nine percent of the total farm area surveyed suffered from root knot nematode attack. Among the several genera of vegetable crop plants surveyed, Lycopersicon esculentum, Dolichos lablab, Solanum melongena, Momordica charantia, Daucus carota,Capsicum annum,Cucumis sativus had root galls. Three species of root knot nematodes Meloidogyne incognita, M. javanica, M. areneria were identified from the above hosts and a comparative morphometric analysis of the body, head and neck size ratios of females were done. Non-significant body and head size variations existing between the females from D. lablab, S. melongena, C. annum, D. carota, L. esculentum showed that all the crops are equally susceptible to root knot nematode attack. However, on the basis of nematode population density, D. carrota appears to be the best suitable host of the Meloidogyne species other than L. esculentum and S. melongena.

Cassava and yam plants are important staple foods of millions of people in the tropical world and provide food security in most parts of sub-Saharan Africa. Their production however is affected by anthracnose disease caused by Colletotrichum gloeosporioides, (Penz.) Penz. and Sacc contributing to 30-70% economic loss in both crops. A study was carried out to determine if variations exist between isolates of C. gloeosporioides on the two crops occurring in different agro-ecological zones of Ghana. Anthracnose-diseased samples of cassava and yam plant parts (leaves and stem/vine) were collected from four agro-ecological zones of Ghana (Forest, Forest-Savannah Transition, Guinea and Coastal Savannah). Isolations of the causal organism C. gloeosporioides were made. The isolates were investigated on the basis of growth characteristics on Potato Dextrose Agar (PDA): presence or absence of setae, colour of cultures, dimensions of conidia. Pathogenicity of isolates was determined and molecular analysis conducted using Random Amplified Polymorphic DNA (RAPD). Results showed both similarities and variations in cultural, morphological and growth characteristics of the pathogen. Isolates from yam caused pathogenic lesions on cassava and yam plant sections and vice versa. Forty-four isolates of C. gloeosporioides from cassava and yam compared by RAPD analysis grouped the isolates into three main clusters. Within two of the clusters are six polymorphic sub-groups relating to host and geographical origin. The different polymorphic sub-groups indicated that there are several sub-populations of C. gloeosporioides isolates, which either singly or in association, involved in the yam and cassava anthracnose infections in the field. Isolates from different ecological zones, with similar morphological features, clustering in a polymorphic sub-group suggest a common origin for some of them.

Published: May 2020

Barley is attacked by many diseases and hence, the study was conducted to quantify and profile barley affecting diseases for management options. The survey was based on the assessment of barley fields at 5 km interval. Results indicated that powdery mildew, leaf rust, stem rust, leaf scald, and smuts were among the important diseases in south Tigray. The prevalence of the former diseases was 60, 60, 40, 47.8, and 40%, respectively. The incidence of powdery mildew, scaled, leaf rust and stem rust was 100% in considerable fields and cultivars. The incidence of smuts was ranged from 5% to 30%. Similarly, the mean severities of powdery mildew, leaf rust, stem rust and leaf scald were 43.4, 54.5, 45 and 20%, respectively, while, smuts caused complete spike losses. Therefore, investigating of the pathogens variability especially for rusts, powdery mildew and scald as well as developing integrated management options for all diseases is of concern.

Published: May 2020

BackgroundWritten discharge communication following inpatient or outpatient clinic discharge is essential for communicating information to the GP, but GPs’ opinions on discharge communication are seldom sought. Patients are sometimes copied into this communication, but the reasons for this variation, and the resultant effects, remain unclear.AimTo explore GP perspectives on how discharge letters can be improved in order to enhance patient outcomes.Design & settingThe study used narrative interviews with 26 GPs from 13 GP practices within the West Midlands, England.MethodInterviews were transcribed and data were analysed using corpus linguistics (CL) techniques.ResultsElements pivotal to a successful letter were: diagnosis, appropriate follow-up plan, medication changes and reasons, clinical summary, investigations and/or procedures and outcomes, and what information has been given to the patient. GPs supported patients receiving discharge letters and expounded a number of benefits of this practice; for example, increased patient autonomy. Nevertheless, GPs felt that if patients are to receive direct discharge letter copies, modifications such as use of lay language and avoidance of acronyms may be required to increase patient understanding.ConclusionGPs reported that discharge letters frequently lacked content items they assessed to be important; GPs highlighted that this can have subsequent ramifications on resources and patient experiences. Templates should be devised that put discharge letter elements assessed to be important by GPs to the forefront. Future research needs to consider other perspectives on letter content, particularly those of patients.

Published: May 2020

BackgroundThe National Early Warning Score (NEWS) calculated from physiological observations provides a simple away to identify and respond to the deteriorating patient. There is increasing interest in the application of NEWS to facilitate referrals from the community.AimTo establish whether elevated NEWS are associated with adverse outcomes at 5 and 30 days when obtained in a community setting at the time of transfer to an acute setting.Design & settingA retrospective service evaluation was undertaken using a database of emergency admissions to secondary care from two NHS district general hospitals within the South of England between January 2018 and April 2019.MethodThe performance of NEWS recorded in a community setting to predict death or critical care admission at 5 and 30 days was calculated using established thresholds.Results2786 referrals from primary care were analysed. The 5 day and 30 day mortality was 2.2% (1.7 to 2.8) and 7.1% (6.2 to 8.1). The prevalence of the composite outcome was 3.4% (2.8 to 4.2) at 5 days and 8.5% (7.5 to 9.6) at 30 days. The risk of adverse outcomes increased incrementally with increasing NEWS. When calculated at the point of referral from primary care the positive predictive value of death at 5 and 30 days was 15% (95% confidence intervals [CI] = 12 to 19) and 23% (95% CI = 17 to 30) in the high-risk NEWS group.ConclusionElevated NEWS obtained in the community during the process of emergency admission are associated with adverse outcomes. Communicating NEWS may allow downstream care to be better calibrated to risk.

Published: May 2020

In this paper we examine the tax treatment of study abroad expenses for students who engage in study abroad activities. Study abroad trips run the gamut from seven day excursions, to full semester trips, and even multiple year, multiple country trips. The type of study abroad trip is important as the tax consequences of certain expenses depend on the type of trip, the duration of the visit, and the role of the participants involved. Educational study abroad expenses may be incurred in either a personal or a business capacity, resulting in very different tax treatments.

Published: May 2020

The aim of the research is to analyse the effect of profitability, liquidity, and company’s size to company’s value and examines whetherDERis a mediating variable. Secondary data is taken from annual report of the companies. Analysis method used is multiple regression analysis (least square). The finding of the research showed thatDER mediated the relationship between CR andTobin’s Q. However DER is not a mediating variable for the relationship betweenRNOAand TOBINas well as between SIZE and Tobin’s Q. Mediating test is conducted by Sobel Test. The other finding is that RNOA positively affects to DER. CR negatively affects to DER. SIZE positively affects to DER and then DER negatively affects to Tobin’s Q. Recommendation for future research is to widen the samples, not just 42 companies, to add observed periods to give clearer description in long term.The next research can also use other dependent variables affecting capital structure and company’s value.

ABSTRACT
Aging process is the process towards the elderly where in humans naturally there is a decrease or change in physical, psychological and social conditions. In physiological changes there is a decrease in the body's immune system in overcoming from inside and outside of the body. One of health disorders that most experienced by the elderly is in cardiovaskular system that is in the elasticity of the aortic wall, the heart valve thickens and becomes stiff, and the heart's ability to pump blood decreases which can lead to hypertension. Management of hypertension there are two ways, pharmacological therapy and non-pharmacological therapy. Therapy that will be used is non-pharmacological therapy (this therapy that does not use drugs). This therapy that will be used is SEFT including relaxation techniques which is one form of mind-body therapy and an alternative treatment in nursing that focuses on the thoughts of the causes of trauma symptoms of problems that can reduce blood pressure. Aims this study is to analized the effect SEFT therapy on blood pressure in elderly with hypertension. The design used pre-experimental with one group pre-post test design approach. Sampel in this study are elderly that have religion Moeslem, who have hypertension as much 30 respondents selected by simple random sampling. Data analysis used Wilcoxon. The majority of respondents residing in the RW 10 Randu Agung area of Kelurahan Sidotopo Wetan Kecamatan Kenjeran Surabaya are aged 60-74 years old, women, doesn’t work, and don’t have history of diseases. The results of statistical tests showed that p value = 0,000 < α = 0,05 it means there is an effect of therapy on blood pressure in elderly who have hypertension. This study shows that applying SEFT can reduce blood pressure in elderly who have hypertension.
