Abstract

Since people living in a karst area periodically face a crisis due to a lack of fresh water, it is necessary to re-evaluate the ability to use water resources. An appropriate and effective management is required to use available water resource sustainably. We describe a management process of exploring underground river in karst region as water resources. The activities completed included four phases, namely exploration, pre-lifting activities, the water lifting and post-lifting activities. The exploration phase included speleological surveys and data collection for the cave mouth using remote sensing instrument. The pre-lifting was done to prepare various requirements before the lifting process was completed. The water lifting phase consisted of the construction of an underground river dam, the installation of submersible pumps, the construction of reservoirs and the installation of piping to connect to the public hydrant. The post-lifting phase was mainly conducted to organise water distribution evenly. This management model was evidenced to successfully overcome drought in Pucung village by providing fresh water to the local community. Moreover, this model promoted residents’ cost savings by reducing their expenses for buying water from IDR 50,000/m3 to IDR 3,500/m3 (1,300 percent).

Abstract

Salah satu penyinaran radioterapi yang menjadi pilihan di berbagai rumah sakit di Indonesia adalah penyinaran kanker otak dengan teknik 2 Dimensi. Di Instalasi Radioterapi RSUD Prof. Dr. Margono Soekarjo menggunakan teknik 2 Dimensi dengan alat teleterapi Cobalt-60 untuk kasus kanker otak. Sehingga penatalaksanaan tumor otak dibutuhkan sebagai rujukan dasar penting untuk dilaksanakan. Penelitian ini dilakukan dengan tujuan mendeskripsikan teknik penyinaran radiorerapi dari teknik penyinaran radioterapi dengan kasus kanker otak dengan menggunakan alat teleterapi cobalt-60. Jenis penelitian ini bersifat deskriptif kualitatif yaitu studi kasus dengan melakukan observasi di Instalasi Radioterapi Rumah Sakit Umum Daerah Prof. Dr. Magono Soekarjo, Purwokerto dari tanggal 1 s/d 29 Mater 2020 dengan mengambil sampel sebanyak 1 orang pasien. Hasil dari penyinaran radioterapi kanker otak dengan menggunakan cobalt-60 adalah radiasi dengan metode 2 dimensi dengan dua lapangan penyinaran yaitu dengan sudut 90° dan 270°. Dosis total radiasi yang diberikan ke pasien sebesar 60Gy dengan fraksi sebanyak 30 kali. Pada penelitian ini tidak menggunakan alat verifikasi untuk mendapatkan posisi target yang sebenarnya.
