LAYANAN CYBERCOUNSELING. SEBUAH ALTERNATIF UNTUK MEMBANTU MENYELESAIKAN MASALAH
Full text linkPada saat individu memiliki masalah dan tidak bisa menyelesaikannya sendiri maka dibutuhkan bantuan orang lain yang diantaranya melalui konseling. Model konseling tradisional dengan tatap muka hingga saat ini masih efektif dipakai disamping dalam perkembangannya muncul berbagai bentuk layanan konseling yang lain. Cybercounseling sebagai sebuah sarana pemberian bantuan konseling yang dilakukan dengan sambungan internet cukup membantu menyelesaikan masalah. Disiapkan web e-konseling dengan fasilitas layanan konseling melalui e-mail dan chat. Dilengkapi dengan keterangan kapan email akan dibalas dan waktu chat yang memungkinkan. Setelah web e-konseling dievaluasi oleh dua konselor senior dan enam belas orang yang berada pada fase dewasa awal, selanjutnya direvisi. Kemudian diujicobakan pada 25 orang dewasa untuk mendapat layanan psikologis melalui cybercounseling selama 6 bulan. Setelahnya dilakukan evaluasi. Hasil evaluasi menyebutkan bahwa 20 orang merasa puas dengan dengan layanan cybercounseling karena efektif waktu tidak perlu meluangkan waktu bertemu konselor, dapat mengekspresikan perasaan tanpa malu karena tidak berhadapan langsung dengan konselor, tidak merasa diadili. Sementara 5 orang lainnya merasa cybercounseling tidak efektif karena dalam proses konseling sambungan internet putus sambung hingga proses konseling terganggu, saat ingin konseling harus menunggu jadual chat, waktu repon e-mail dari psikolog/konselor dianggap terlalu lama, psikolog/konselor dianggap tidak memahami secara mendalam apa yang dirasakan. Untuk mengatasi ketidakpuasan pada layanan cybercounseling, konseling tradisional tatap muka dilakukan dan pemberian dukungan melalui sms (short message service

Implementation of Least Significant Bit Steganography to Secure Text Messages in Images
Full text linkSteganography is a technique of securing secret messages in other messages that are not known. Simulation of the steganography method using the Least Significant Bit technique is used to change the last bit in one byte of data by using a text message as the container medium. This study aims to implement the security of text messages in images using the Least Significant Bit technique which is supported by the steganography method. Simulation techniques are used to conduct studies using Cryptool2 which can describe the concept of cryptography. The results obtained from this study regarding the security of text message insertion into an image in *.jpg and *.png format with 5 sampling trials are (1) the encrypted image cannot be distinguished directly through human eyes, (2) there is an increase in file size the image after being encrypted with an average for five trials is 0.31%, this increase depends on the length of the text message and a key to be inserted, the longer the insertion, the larger the resulting file size, (3) The higher the resolution of the image where the description encryption is inserted, the longer the process required, (4) The simulation time of steganographic decryption is faster than steganographic encryption. The decryption simulation process is the same as 50% of the encryption process
