ABSTRAK

Kestabilan lubang bukaan merupakan suatu faktor yang sangat menentukan kelancaran kegiatan penambangan bawah tanah. Agar menjadi suatu metode penambangan yang aman, maka perlu dilakukan suatu penelitian tentang kestabilan lubang bukaan (open stope) pada saat dan setelah dilakukan penambangan dengan metode long hole stope (LHS). Kajian ini dilakukan berdasarkan metode empiris dan permodelan numerik.

ABSTRACT 

PT Nusa Halmahera Minerals (PT.NHM) is a gold mining company which operating in the Kencana– Gosowong, North Halmahera Regency, North Maluku Province-Indonesia. From the evaluation results, Underhand Cut and Fill method (UCF) has been chosen because of several considerations, among others, low cash flow, high recovery, and more secure in the face of poor rock conditions. But the problem that must be faced is about the stability of pastefill that act as a roof for workers and mine equipment below.

ABSTRACT

PT Nusa Halmahera Minerals (NHM) is a gold mining company which located in North Halmahera, North Maluku Province, Indonesia. One of NHM mine site is Kencana Underground Gold Mine which applying Underhand Cut and Fill (UCF) mining method. Backfill material used in this side is pastefill type. Stability analysis of pastefill block needs to be carried out due to the reason that it will act as back (roof) when underneath stope is opened. This research is carried out in Kencana 2 Sub 12 C undercut 3 Ore Drive (OD) 1 North.

Abstract 

The stability of the stope opening is a factor that greatly determines succesfull operation of an underground mining. In order to be a safe mining method by using paste fill, it is necessary to do a research on the stability of paste fill which is used to fill the mining stope. The study was conducted based on the analytical method and numerical modeling. The limit equilibrium method was used to analysis the stability of paste fill considering the acting forces and mechanical strength of paste fill, for numerical modeling was used distinct element method with the program of 3DEC version 4.00 from Itasca, used to displacement analysis of paste fill that can be slided and collapsed by using the rigid and deformeable analysis. The stability analysis of paste fill was perform to ensure safety of mining activities in Kencana underground gold mine.  

 

Keywords: Stability; paste fill; factor of safety; stope; numerical modeling; displacement

Pendidikan Karakter Sebagai Upaya Pembentukan Jati Diri Anak (Jurnal Dodoto Vol.2 No 2 Des 2011, ISSN 2087-6556)

Oleh: Nahjiah Ahmad ,Dosen Fakultas Ilmu Pendidikan UMMU

 

Abstrak

Pendidikan adalah suatu usaha yang sadar dan sistematis dalam mengembangkan potensi peserta didik. Pendidikan karakter dapat dimaknai sebagai pendidikan nilai, budi pekerti, pendidikan moral, pendidikan watak, yang bertujuan mengembangkan kemampuan peserta didik untuk memberikan keputusan baik buruk, memelihara apa yang baik, dan mewujudkan kebaikan itu dalam kehidupan sehari-hari dengan sepenuh hati. Pendidikan karakter dapat pula dimaknai sebagai upaya yang terencana untuk menjadikan peserta didik mengenal, peduli dan menginternalisasikan nilai-nilai sehingga peserta didik berperilaku sebagai insan kamil. Upaya mensinergikan pendidikan rumah dan sekolah, adalah adanya jalinan komunikasi dan kolaborasi antara pihak keluarga dan sekolah. Jalinan komunikasi dan kolaborasi ini diperlukan untuk membangun kesepaatan langkah dan program-program sekolah dengan harapan dan dukungan orang tua. Program-program sekolah dipahami dan didukung oleh pihak orang tua; sebaliknya, harapan-harapan orang tua juga dipahami dan dipertimbangkan oleh pihak sekolah.

Kata Kunci : Pendidikan, karakter, jati diri anak
