Abstract

Salah satu cara untuk meramalkan sisa waktu produksi yang akan datang dan memperkirakan sisa cadangan (remaining reserve) dengan metode analisa kurva penurunan produksi atau yang disebut dengan istilah Decline curve analysis. Metode ini sangat cocok untuk mengetahui jumlah sisa cadangan pada lapisan “JNT-A1” lapangan “Z” yang telah di produksikan, dimana trend produksinya telah menurun. Penelitian ini bertujuan untuk mengetahui jumlah sisa cadangan (remaining reserve), mengetahui trend penurunan produksi, Mengetahui sisa waktu produksi, mengetahui recovery Factor (RF) dan mengetahui ultimate Recovery (UR). Setelah dilakukan analisa Decline curve pada Lapisan “JNT-A1” lapangan “Z” berdasarkan data yang diberikan, initial gas in place (IGIP) atau jumlah gas mula – mula pada lapisan JNT-A1 lapangan Z sebesar 98,69 BSCF. Dan berdasarkan metode loss ratio diperoleh recovery factor sebesar 43,019% sedangkan metode trial error and X2 chisquare diperoleh harga recovery factor sebesar 49,223 %, berdasarkan perhitungan menggunakan metode loss ratio diperoleh ultimate recovery sebesar 42455 MMSCF sedangkan perhitungan menggunakan metode trial error and X2 chisquare diperoleh harga ultimate recovery sebesar 48579 MMSCF. Berdasarkan parameter tersebut maka penulis memilih metode trial error and X2 chisquare sehingga jumlah dari sisa cadangan (remaining reserves) pada lapisan “JNT-A1” lapangan “Z” sebanyak 6901 MMSCF.

Therefore, this study aimed to analyze the effectiveness of Observe and Remember Game on students’ vocabulary mastery. The writers applied some procedures namely pretest, treatment by using Observe and Remember game then conducting the posttest after applying the game. To analyze the data, t-test was applied using using SPSS to get the mean scores. From the result of the statistical calculation, the average score of the pretest was 49.82, the result of the posttest was 68.46. It increased by 18.64%. It could be summarized that Observe and Remember game was effective on students’ vocabulary mastery
