Improved Stroke Detection at Early Stages Using Haar Wavelets and Laplacian Pyramid

Stroke merupakan pembunuh nomor tiga di dunia, namun hanya sedikit metode tentang deteksi dini. Oleh karena itu dibutuhkan metode untuk mendeteksi hal tersebut. Penelitian ini mengusulkan sebuah metode gabungan untuk mendeteksi dua jenis stroke secara simultan. Haar wavelets untuk mendeteksi stroke hemoragik dan Laplacian pyramid untuk mendeteksi stroke iskemik. Tahapan dalam penelitian ini terdiri dari pra proses tahap 1 dan 2, Haar wavelets, Laplacian pyramid, dan perbaikan kualitas citra. Pra proses adalah menghilangkan bagian tulang tengkorak, reduksi derau, perbaikan kontras, dan menghilangkan bagian selain citra otak. Kemudian dilakukan perbaikan citra. Selanjutnya Haar wavelet digunakan untuk ekstraksi daerah hemoragik sedangkan Laplacian pyramid untuk ekstraksi daerah iskemik. Tahapan terakhir adalah menghitung fitur Grey Level Cooccurrence Matrix (GLCM) sebagai fitur untuk proses klasifikasi. Hasil visualisasi diproses lanjut untuk ekstrasi fitur menggunakan GLCM dengan 12 fitur dan kemudian GLCM dengan 4 fitur. Untuk proses klasifikasi digunakan SVM dan KNN, sedangkan pengukuran performa menggunakan akurasi. Jumlah data hemoragik dan iskemik adalah 45 citra yang dibagi menjadi 2 bagian, 28 citra untuk pengujian dan 17 citra untuk pelatihan. Hasil akhir menunjukkan akurasi tertinggi yang dicapai menggunakan SVM adalah 82% dan KNN adalah 88%

Pengaruh Berbagai Jenis Penggumpal Padat Terhadap Mutu Koagulum Dan Vulkanisat Karet Alam

Mutu bahan olah karet masih rendah dan bervariasi akibat tidak tersedianya koagulan yang baik sampai ke tingkat petani. Penggunaan koagulan yang tepat untuk menghasilkan bokar bermutu baik masih belum sepenuhnya dilakukan akibat belum tersedianya koagulan yang mudah didistribusikan, kompetitif dari segi harga, dan tidak merusak mutu karet. Penelitian ini mempelajari pengaruh berbagai jenis penggumpal padat terhadap mutu koagulum dan vulkanisat karet alam. Bahan penggumpal ditambahkan ke dalam lateks kebun berpengawet ammonia pada dosis 7g/kg karet. Lateks yang telah diberi perlakuan dibiarkan menggumpal selama dua minggu, selanjutnya karet digiling dan dikeringkan dalam oven pada suhu 100°C selama 2-3 jam. Karet kering diuji sifat kimianya (PRI, kadar kotoran, kadar abu, dan kadar zat menguap), setelah itu dibuat vulkanisat dengan resep kompon ASTM 2A. Kompon karet diuji karakteristik vulkanisasinya dengan rheometer, kemudian vulkanisat diuji sifat fisika (kekuatan tarik, perpanjangan putus, modulus 300 % dan kekerasan). Sebagai pembanding digunakan asam format. Hasil penelitian menunjukkan bahwa penggunaan asam organik dan garam anorganik sebagai bahan penggumpal memiliki kelebihan dan kekurangan masing-masing. Kombinasi antara bahan asam dengan garam anorganik diharapkan dapat memberikan hasil yang lebih baik sehingga mutu bahan olah karet akan meningkat.

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.

Analisis Pengaruh Book-tax Differences Terhadap Persistensi Laba

This study aims to obtain empirical evidence about the role of differences between accounting income and taxable income (book-tax differences) of earnings one period ahead. In addition this study aims to test whether the difference between accounting earnings and taxable income will also affect investors' assessment of earnings persistence in the future. The hypothesis proposed is: (1) firms with large book-tax differences has a lower accounting earnings persistence than firms with small book-tax differences, (2) firms with large book-tax differences has a persistence of accrual components is lower than companies with small book-tax differences. The samples used were 40 companies listed in Indonesia Stock Exchange (IDX), and publish audited financial statements are consistent in the year 2000-2005. The data was collected using purposive sampling. The statistical methods used are panel data regression. The results showed that firms with large large book-tax differences of having lower earnings persistence than firms with small large book-tax differences. However, the low persistence of earnings is not statistically proven due to the accrual component. Investors have not been able to distinguish the information contained in accruals and cash flow component in determining the persistence of earnings. Information about the size of the large book-tax differences contained in accruals component can not affect investors' assessment of earnings persistence in the futur
