Abstract: Effort estimation using Use Case Point (UCP) method obtained from the multiplication of the UCP with the Effort Rate (ER). Some studies conclude that there is some value of ER used in the calculation of effort estimation. However, the most often used is the ER with value 20 man-hours given by Karner. Disputes about the research that is ER by Karner occurred in 1993, so it is possible that the ER by Karner not suitable when applied in the calculation of effort estimation for the project worked on in 2013 and the years to come. This study used 8 data of governance website software development projects. The data is used to calculate actual effort, making use case diagrams, and calculations UCP estimation. Further level of analysis that is performed correlation and regression equations for actual effort and the UCP estimation. Based on the regression equation then performed calculations tangent θ to produce the ER. From this research produced the ER as big as 5,178 man-hours. The ER is much smaller than the value given by Karner ER. Case is possible for several reasons, among others: 1) Enginering software technology that is growing rapidly. 2) Manufacturing website using components. 3) Source of the internet so complete.

Abstract

Keunikan kota-kota kecil tradisional di negara timur terletak pada kesinambungan dan keterkaitan antar budaya, iklim dan seni-kriya, apabila hal ini sebagai kecenderungan perkembangan kota yang intuitif tetapi juga rasional mampu dibina terus, tidak akan pernah muncul kerisauan akan krisis identitas. Seorang arsitek mempunyai tanggung jawab yang besar untuk bertukar, menyumbangkan karya yang suatu saat nanti dinilai layak dilestarikan. Sebagai negara yang memiliki sejarah yang panjang, dengan tradisi yang kuat dan beragam serta pengalaman dijajah negara lain, tak pelak kita memiliki warisan arsitektur tradisional dan peninggalan kolonial yang sangat kaya, tersebar di berbagai pelosok kota. Hal inilah yang dapat kita jumpai di Kabupaten Wonosobo yang tercatat sebagai kota kedua setelah Yogyakarta yang menyatakan bergabung dengan Republik ini, sehingga akan menjadi lebih menarik lagi untuk dijadikan sebagai bahan kajian Penelitian Studi Literatur yang memadukan data lapangan dengan data pustaka dan dilengkapi dengan wawancara para pelaku sejarah untuk memperoleh hasil yang maksimal. Penelitian ini bertujuan untuk mengidentifikasi objek penelitian. Data yang ada dalam penelitian ini diperoleh dengan menggunakan metode observasi untuk mengidentifikasi objek penelitian sebagai data utama dalam penelitian dan dilengkapi dengan kajian data pustaka yang terkait dengan bangunan cagar budaya yang ada di Kota Wonosobo.
