Abstract
ABSTRAK Daerah penelitian terletak di daerah “WS” Kecamatan Merapi Timur, Kabupaten Lahat, Propinsi Sumatera Selatan. Secara geogafis terletak pada 3o30’25”- 3o44’20” LS dan 103o29’30” - 103o53’30’’ BT. Penelitian ini menggunakan metode well logging dengan titik bor sebanyak 20 titik bor. Tujuan penelitian ini adalah untuk menganalisa dari hubungan data log densitas dan log Gamma ray dengan kalori, total moisture serta kandungan abu pada lapisan batubara. Hasil penelitian menunjukkan bahwa batubara pada daerah penelitian memiliki rata – rata nilai densitas 1,58 gr/cc, total moisture 39,32 %, kalori 5491,66 cal/g dan kandungan abu 6,54 %. Dengan menggunakan metode trideline scatterplot bivariant digunakan untuk mendapatkan hubungan korelasi dari 2 variabel, dimana pada daerah penelitian memiliki hubungan kuat – sangat kuat. Dari hasil hubungan antara density dengan total moisture memiliki variasi positif R2 = 72,07 %. Hubungan antara densitas dengan kalori memiliki variasi positif R2 = 68,66 %. Hubungan antara densitas dengan kandungan abu memiliki variasi negatif R2 = 79,48 %. Hubungan kandungan abu dengan kalori memiliki variasi positif R2 = 69,54 %. Hubungan antara Vshale dengan kandungan abu dengan kalori memiliki nilai variasi positif R2 = 65,95 %. Hubungan antara total moisture dengan kalori memiliki variasi positif R2 = 60,88 %. Semakin besar Vshale maka densitasnya semakin kecil, sehingga semakin banyak Vshale kualitas batubara semakin jelek. Dilihat dari hasil hubungan tersebut kualitas batubara pada daerah penelitian adalah kualitas baik. Pada korelasi antar sumur dapat dijelaskan semakin ke arah barat semakin menunjam dan semakin ketimur lapisannya semakin naik. Kata kunci : well logging, log density, total moisture, kalori, kandungan a ABSTRACT The research area is located in the "WS" Eastern District of Merapi, Lahat Regency, South Sumatra Province. Generally geogafis located at 3 ° 30'25 "- 3 ° 44'20" S and 103 ° 29'30 "- 103 ° 53'30 '' BT. This study uses well logging with drill point drill as many as 20 points. The purpose of this study was to clicking analysis of the relationship log data density and gamma ray logs with calories, total moisture and ash content in the coal seam. The results showed the average of coal density was of 1.58 g / cc, a total of 39.32% moisture, calories 5491.66 cal / g and ash content of 6.54%. By using bivariant scatterplot trideline methode to obtain the correlation of the two variables, whereas in this area has a strong relationship till very strong. From the results of the relationship between the total moisture density has a positive variation of R 2 = 72.07%. The relationship between the caloric density has a positive variation of R 2 = 68.66%. The relationship between the density of the ash content has a negative variation of R2 = 79.48%. jRelationship with the calorie content of ash has a positive variation of R 2 = 69.54%. The relationship between Vshale the calorie content of ash with a positive variation values R2 = 65.95%. The relationship between total moisture with calories has a positive, R 2 = 60.88%. Results of the relationship of coal quality in the study area is of good quality. On the correlation between wells can be explained further to the west is getting more lower, and further east is getting uper. Keywords: well logging, log density, total moisture, calories, ash content.
