Abstract

Competing risk failure time data occur frequently in medical a number of methods have been proposed for the analysis of these data. The classic approach is to model all cause-specific hazards and then estimate the cumulative incidence curve based on these cause-specific hazards. Unfortunately, the cause-specific hazard function does not have a direct interpretation in terms of survival probabilities for the particular failure type.  In this paper, we consider a more flexible model for the subdistribution. It is a combination of the additive model and the Cox model and allows one to perform a more detailed study of covariate effects. One advantage of this approach is that our regression modeling allows for non-proportional hazards. This leads to a new simple goodness-of-fit procedure for the proportional subdistribution hazards assumption that is very easy to use. We applied this method to melanoma data and estimated the cumulative death rate for those who died from melanoma after surgical removal of the tumor. It was found that two covariates had a time-varying effect and two other covariates had a constant effect in predicting the cumulative incidence curve in patients who died of melanoma following tumor removal surgery.

Abstract

Pada dasarnya Negara Indonesia merupakan sebuah negara hukum. Hal ini sesuai dengan Pasal 3 ayat 1 UUD 1945 yang berbunyi yaitu “Negara Indonesia adalah Negara Hukum”. Hukum memiliki fungsi sebagai pelindung kepentingan manusia, agar kepentingan manusia terlindungi, hukum harus dilaksanakan secara profesional, termasuk di dlaamnya adalah penegakan hukum tindak pidana korupsi. Metode Penelitian yang digunakan dalam penulisan ini, adalah metode yuridis normatif dengan pendekatan studi kepustakaan yang merupakan penelitian hukum yang berpusat pada norma hukum termasuk asas, norma, kaidah, peraturan perundang-undangan, perjanjian, dan doktrin. Hasil dan pembahasan menemukan bahhwa faktor dari terjadinya tindak pidana korupsi salah satunya adalah adanya perintah dari atasan yang mungkin bertentangan dengan hati nurani pegawai bawahan selain dari adanya korupsi yang terjadi karena adanya kesempatan untuk melakukannya. Kemudian negara China memiliki konsep yang lebih komprehensif dan berorientasi penghukuman pada kerugian negara yang diambil, bukan tindakan yang dilakukan oleh terdakwa. Untuk merealisasikannya perlu merubah ketentuan Pasal 2 ayat (2) UU Tipikor agar pemberlakuan hukuman mati tidak didasarkan pada anasir non yuridis, namun berkaitan dengan anasir kerugian negara yang nyata konkrit adanya.

Abstract

Land use is defined as human intervention in natural and human-made resources with the aim of fulfilling spiritual and material needs. Land use is inseparable from the phenomenon of land use change. Boyolali District is certainly not exempt from the phenomenon of land use change. Land use conversion has an impact on the inconsistency between land use and its designated plan. This study aimed to analyze land use changes from 2011 to 2022 and assess the suitability of land use in 2022 with the spatial plan of Boyolali District. This study applied survey and spatial analysis methods. The overlay technique produces maps of land use changes and the suitability of land use in 2022 with the Rencana Tata Ruang Wilayah (RTRW = Regional Spatial Planning) of Boyolali District. The results of the research showed that Kabupaten Boyolali experienced a land use conversion of 210.74 km2. Kecamatan Juwangi had the largest change in land use, covering an area of 30.37 km2, while Kecamatan Banyudono had the smallest change of 1.05 km2. The suitability of land use in 2022 with the Rencana Tata Ruang Wilayah (RTRW = Regional Spatial Planning) of Boyolali District indicates a suitable class covering an area of 797.24 km2, while an unsuitable class covers an area of 297.15 km2.
