Abstract

Between 74 and 85% of health documentation in advanced countries is conducted by internet, and 80% of customers use those data to seek information related to health service. The research reported in the present paper is aimed at finding out the influence of leadership style of head of ward, electronic documenting, and nurse performance on service innovation in Meuraxa Hospital in 2017. This study is a cross-sectional; survey of 100 nurses at Meuraxa Hospital who were doing electronic documentation. Structural equation modelling (SEM) showed that the respondents’ perception of the leadership style of the head of the ward is agree and strongly agree where the average is 4.22. The respondents’ perception on the use of electronic documentation is agree and strongly agree where the average index is 4.20; and most of respondents’ perception on the innovation on nursing service is agree and strongly agree where the average index is 4.23. All the indices are in the cutoff value range. The result of this study shows a positive correlation: there is an influence of head of ward leadership style on the performance of nurse; the electronic documentation has an effect on the performance of the nurses; the performance of nurses has an effect on the innovation of nursing service; The leadership style of head of ward affects the innovation of nursing service. the electronic documentation can influence the improvement of nursing service innovation. There is an indirect influence of head of ward leadership style, electronic documentation, nurse perfomance on nursing on service innovation through nurse performance. The alternative hypotheses are accepted and fit model test is good. It is hoped that all head of wards and nurses can improve their service by doing documentation comprehensively.

Abstract

Adanya file gambar hasil scan tidak memiliki kualitas yang bagus(blur). Citra blur ini menyebabkan objek yang terdapat didalamnya menjadi tidak terlihat jelas. Tujuan dari penelitian ini adalah untuk meningkatkan kualitas citra pada dokumen dari hasil scan dengan melakukan deblurring dengan menggunakan algoritma Lucy Richardson Deconvolution. Teknik yang digunakan untuk menghilangkan kekaburan citra (deblurring), penapisan dengan merestorasi citra dengan menggunakan metode iteratif, yaitu algoritma Lucy-Richardson. Metode Lucy-Richardson dapat melakukan deblurring pada citra dengan nilai threshold 192. Maksimal blur yang bisa di deblurring adalah sampai dengan 50% blur pada citra menggunakan pengujian PSNR dengan nilai mininum 30dB. Penerapan metode Lucy-Richardson menggunakan 1 parameter (Threshold), sehingga lebih memudahkan untuk mendapatkan hasil citra yang paling optimal

Abstract

Society 5.0 can also be interpreted as a concept of a human-centered and technology-based society. The competency model will support the effectiveness of the recruitment and selection process so that companies can attract the talents needed to build their HR performance. Thus, the development of a competency model for Society 5.0 has considerable value in terms of education, training, and human development perspectives in facing the era of change, especially Society 5.0. The purpose of this study is to conduct an in-depth analysis of existing research and practice competency models and continue the development of competency models for Society 5.0. The research method uses Systematic Literature Review (SLR) is a research method used to collect, review and synthesize relevant literature in a particular research field. A literature search was conducted through academic databases, such as PubMed, ERIC, and Google Scholar, using appropriate keywords such as “human resource competency”, “society 5.0”.  Next, this data is analyzed to identify patterns, trends, and consistencies in the findings. This study found that concepts of industrial revolution 4.0 and Society 5.0 focus on increasing the digitalization of the value chain, with humans as the main component in Society 5.0. To face the Society 5.0 era, human resources need to adapt to future challenges with high-level thinking abilities. Society 5.0 presents opportunities and challenges for companies. Human resource competency requires hard skills that are adapted to the Society 5.0 era.

Abstract

Lamtoro leaves (Leucaena leucocephala) have long been a traditionally used plant because they are rich in nutrients and have several health benefits. Antioxidants are compounds that can protect organisms from oxidation and free radicals, which are factors that cause cell damage. This study aims to determine the IC50 value and antioxidant activity of 70% ethanol extract and acetone extract from lamtoro leaves. The extraction of lamtoro leaves was carried out using the soaking method with 70% ethanol solvent and acetone solvent, respectively. The antioxidant activity test was carried out by determining the free radical inhibitory activity of DPPH (2,2-diphenyl-1-picrylhydrazyl). Absorbance measurements were carried out using a UV-Vis Spectrofotometer at a wavelength of 517 nm. 70% ethanol extract and acetone extract of lamtoro leaves have very strong antioxidant activity with IC50 values of 41.18 ppm and 3,87 ppm, respectively. This result is the same as the comparison, namely vitamin C, which also has very strong antioxidant activity with IC50 value of 1.42 ppm. The conclusion of this research is that the acetone extract of lamtoro leaves have very strong antioxidant activity because they are still in the range of less than 50 ppm.

Abstract

Lobak putih (Raphanus sativus L.) merupakan tanaman yang mengandung flavonoid, fenolik, dan saponin yang berperan sebagai antioksidan. Flavonoid merupakan senyawa fenolik alami yang sangat umum ditemukan pada berbagai jenis tanaman. Senyawa ini mengandung satu atau lebih gugus hidroksil (-OH) yang terikat pada cincin aromatik. Penelitian ini bertujuan untuk menganalisis perbedaan jenis pelarut terhadap kadar total flavonoid dan fenolik dalam ekstrak umbi lobak putih. Penelitian yang dilakukan merupakan penelitian eksperimental laboratorium. Tahapan penelitian meliputi pengambilan sampel, pembuatan simplisia, ekstraksi maserasi umbi lobak putih dengan menggunakan variasi pelarut yaitu etanol 70%, Etil Asetat, dan N-heksana. Pengukuran kadar flavonoid dan fenolik total dilakukan menggunakan spektrofotometer UV-Vis.Hasil skrining fitokimia pada masing-masing ekstrak mengandung senyawa metabolit sekunder yaitu alkaloid, flavonoid, saponin, tanin dan fenolik. Diperoleh kadar total flavonoid ekstrak umbi lobak putih pada pelarut etanol 70%, Etil Asetat, dan N-heksana berturut-turut 3,433 ± 0,298 mgQE/g; 0,146 ± 0,012 mgQE/g; 0,516 ± 0,026 mgQE/g. Sementara kadar total fenolik berturut-turut yaitu 24,53 ± 0,502 mgGAE/g; 4,4 ± 2,367 mgGAE/g; 6,65 ± 4,038 mgGAE/g. Berdasarkan hasil  analisis One Way ANOVA membuktikan bahwa variasi jenis pelarut memberikan pengaruh yang nyata terhadap kadar flavonoid dan fenolik total ekstrak umbi lobak putih dengan nilai signifikansi masing-masing 0,000* dan 0,001* (P<0,05).
