Aktivitas Sitotoksik Ekstrak Etanol dan Fraksi-Fraksi Daun Selaginella willdenowii terhadap Sel Kanker Payudara T47D

Breast cancer is a type of cancer with the highest percentage of new cases and death in Indonesia. Cancer treatment has been causing adverse effects, thus triggering the development of alternative medicines derived from nature or plants as anticancer therapy. Selaginella willdenowii is one of plants that has anticancer activity. The purposes of this research were to investigate cytotoxic activity of ethanol extract and fraction of S. willdenowii leaves against T47D breast cancer cell and to determine the class of compound in the active fraction. The leaf extract of S. willdenowii was obtained by maceration method using 96% ethanol. The cytotoxic assay was performed based on MTT assay method. The group of compounds contained in ethyl acetate fraction were identified using Thin Layer Chromatography (TLC) method. The result of cytotoxic test showed that the ethyl acetate fraction of S. willdenowii leaf have weak cytotoxic activity on T47D cancer cell with IC50 value of 259,380 μg/mL meanwhile ethanol extract, n-hexane fraction, and ethanol-water fraction did not have cytotoxic activity against breast cancer cells T47D. Doxorubicin as positive control has IC50 value of 39,770 μg/mL. The results of phytochemical analysis showed that ethyl acetate fraction of S. willdenowii leaves contains alkaloids, flavonoids, and terpenoids

TEACHING READING COMPREHENSION BY USING THINK ALOUD STRATEGY OF SMAN 9 BANYUASIN

The objective of this research was to find out whether or not it is effective to use think aloud strategy in teaching reading comprehension to the eleventh grade students at SMAN  9 Banyuasin. This research used quasi-experimental. The sample were 61 students which taken through convenience sampling. The data were analyzed by using independent sample t-test. . The result of t-obtained was 4.649, t- table was 1.67. As we know, t-obtained was higher than  t-table. It means that it is effective to teach reading analytical exposition text by using think aloud Strategy to the eleventh grade students of  SMAN 9 Banyuasin

Convolutional Neural Network and Feature Transformation for Distant Speech Recognition

In many applications, speech recognition must operate in conditions where there are some distances between speakers and the microphones. This is called distant speech recognition (DSR). In this condition, speech recognition must deal with reverberation. Nowadays, deep learning technologies are becoming the the main technologies for speech recognition. Deep Neural Network (DNN) in hybrid with Hidden Markov Model (HMM) is the commonly used architecture. However, this system is still not robust against reverberation. Previous studies use Convolutional Neural Networks (CNN), which is a variation of neural network, to improve the robustness of speech recognition against noise. CNN has the properties of pooling which is used to find local correlation between neighboring dimensions in the features. With this property, CNN could be used as feature learning emphasizing the information on neighboring frames. In this study we use CNN to deal with reverberation. We also propose to use feature transformation techniques: linear discriminat analysis (LDA) and maximum likelihood linear transformation (MLLT), on mel frequency cepstral coefficient (MFCC) before feeding them to CNN. We argue that transforming features could produce more discriminative features for CNN, and hence improve the robustness of speech recognition against reverberation. Our evaluations on Meeting Recorder Digits (MRD) subset of Aurora-5 database confirm that the use of LDA and MLLT transformations improve the robustness of speech recognition. It is better by 20% relative error reduction on compared to a standard DNN based speech recognition using the same number of hidden layers

Number recognition development with number card: Single subject research

Mentally retarded is a mental disorder with an intelligence quotient (IQ) between 55-70, besides those mentally retarded children are only able to think concretely. For this reason, learning mathematics for mentally retarded students requires learning media that can bridge abstract mathematical material with the abilities of mentally retarded children who are only able to think concretely. The objective of this study was to improve the recognition of 1-20 numbers using number cards for students with mild mental retardation. The research used is single subject research method with basic design non reversal. Study subjects were selected based on a purposive sampling technique, as the researcher had to look for subjects with mild mental retardation. Data collection techniques use documentation to find out subjects with mild mental retardation characteristics, and tests to determine the subject's ability to recognize numbers 1-20. The results of this study indicate that the number card media can improve the ability of mild mentally retarded students to recognize numbers 1-20. This can be seen from the average in the baseline phase of 39 with a percentage of the ability to recognize numbers of 33.3%, and in the intervention phase of 74.44 with a percentage of the ability to recognize numbers of 88.89%

Pendampingan Pengurusan Ijin PIRT dan Pembuatan Label Baru Pada Produk-Produk UMKM Bumdes “Karya Mandiri” di Desa Sidorejo untuk meningkatan mutu Produk

Virus Covid-19 atau yang bisa disebut virus Corona menyerang semua usahamikro dan Usaha Kecil Menengah (UKM) memang paling rentan terkena dampakpandemi virus. Oleh karena itu, masyarakat pemilik perusahaan harus memikirkanbagaimana bisa menguntungkan bertahan dari pandemi. Ditambah para pelaku UMKM belum memiliki surat ijin PIRT pada produk mereka. Melalui kegiatan yang kami laksanakan yaitu “Pendampingan Pengurusan Ijin PIRT dan Pembuatan Label Baru Pada Produk-Produk UMKM Bumdes Karya Mandiri di Desa Sidorejo”. Tujuan dari kegiatan KKN ini adalah agar mahasiswa dapat menempatkan diri dalam masyarakat serta belajar dari masyarakat serta membantu masyarakat dan UMKM untuk meningkatkan kualitas produknya

Factors Influencing Financial Performance Through Sustainability Reporting in Indonesia

The study aims to examine factors influence financial performance through sustainability reporting. The sample is companies that received an Indonesia Sustainability Reporting Awards (ISRA) in 2016. This study uses secondary data from the annual report 2012-2016. The first result shows that board size and sustainability are not significant. The second and third result shows the size and leverage have a positive impact on sustainability reporting. The last result shows that sustainability reporting has a positive and significant effect on financial performance. The contributions in this study, first, it shows the mediating effect of sustainability reporting on the relationship between these factors and financial performance. Second, this study also investigates companies that received ISRA in 2016. The limitation of this study is that it focuses on companies that received the award from ISRA in 2016. Another limitation, the framework is not the best framework

Ukuran Dewan, Ukuran Perusahaan, Leverage, Profitabilitas Berpengaruh terhadap Laporan Berkelanjutan Di Indonesia

Tujuan dari penelitian ini adalah untuk menguji ukuran dewan, ukuran perusahaan, leverage dan profitabilitas terhadap laporan keberlanjutan (sustainability reporting). Sampel dalam penelitian hanya berfokus pada perusahaan yang menerima penghargaan dari Indonesia Sustainability Reporting Awards (ISRA). Penelitian ini menggunakan teori agensi (agency theory) dan teori legitimasi (Legitimacy theory) dan teori stakeholder (Stakeholder theory). Temuan penelitian ini menunjukkan bahwa Ukuran perusahaan berpengaruh positif dan signifikan terhadap laporan berkelanjutan. Leverage juga berpengaruh negatif dan signifikan terhadap laporan berkelanjutan. Namun, ukuran dewan dan profitabilitas tidak signifikan berpengaruh terhadap laporan keberlanjutan. Kelemahan dari penelitian ini adalah bahwa sampel hanya berfokus pada perusahaan yang menerima ISRA, sehingga penelitian selanjutnya menggunakan lebih banyak sampel di bidang yang sama sebagai contoh sektor pertambangan untuk perusahaan listed di Bursa Efek Indonesia.Keywords:board size, company size, leverage, profitability, sustainability reportin
