Abstract

Lubang bor hasil pengeboran berarah yang memiliki kolom yang panjang pada formasi yang mempunyai litologi sebagai zona lost circulation alami dimana tekanan hirostatis fluida penyemenan lebih besar dari tekanan maksimum formasi memiliki potensi yang besar terjadinya lost circulation saat proses penyemenan. Salah satu solusi yang dapat digunakan adalah mengurangi tekanan hidrostatis fluida penyemenan dengan metode dual stage cementing. Penentuan metode penyemenan casing 7 inch pada trayek 8.5 inch ditentukan dengan cara melakukan interpretasi data master log, melakukan korelasi sumur dan membandingkan tekanan maksimum formasi dengan tekanan hirostatis fluida penyemenan, kemudian dilakukan perhitungan pada design penyemenan. Berdasarkan data master log diketahui bahwa litologi sumur didominasi oleh batuan shale, sandstone dan limestone. Tekanan maksimum formasi sebesar 3.642,6488 psi sedangkan tekanan hidrostatis fluida penyemenan sebesar 4.363,3186 psi, jika dilakukan penyemenan dengan cara normal maka formasi akan pecah sehingga penyemenan dilakukan dengan metode dual stage cementing dengan membagi penyemenan kedalam dua tahap yaitu stage 1 pada interval 821,75 –1.812,40 mMD selanjutnya Stage 2 pada interval 0 – 821,75 mMD. Dari hasil perhitungan pada design penyemenan didapat total fluida penyemenan yang dibutuhkan adalah 425,1396 bbl pada stage 1 dan 248,5022 bbl pada stage 2 yang terdiri dari semen slurry, displacement, spacer dan fresh water.Kata kunci : Pemboran, hidrostatis, formasi, Penyemenan, loss sirkulasi

Abstract

This research uses the design of the plot divided with the treatment of ex- planting is the main plot whereas the other treatment is a subplot consisting of 2 (two) factors and repeated 3 times. The first factor is rotation of Soybean-Rice and Corn-Rice Planting. The second factor was treatment of fertilizer composition, P0 (control), P1 (100% compost), P2 (50% compost + 50% N inorganic), P3 (75% compost + 25% N inorganic). The treatment (L2P1) yielded the highest 1000 grain weight of 25.28 g, L2P3 yielded the highest amylose content of 20.51%, L1P0 resulted in amylopectin content of 58.42%. The treatment of L2 resulted in 0.92 kg dry weight of dry paddy grain, yield 1000 grains weighing 25.10g, 19.23% amylose and L1 treatment yield the highest amylopectin content of 54.39%. The treatment (P2) resulted in the highest plant length of 102.67cm, P1 yielding 1000 grains of 24.36g, P3 yield amylose content of 20.00%, P0 yielding amylopectin content of 57.72%.

Abstract

The formulation of the problem in this study is the lower the number of AUTP participants in Sungai Pinyuh District, so the purpose of this study is to analyze the level of motivation, the level of participation and the relationship between motivation and participation. This study uses the Likerta scale method (descriptive) then the range spermant test to find a relationship. The research location was chosen by purposive sampling, this means that the Sungai Pinyuh sub-district is an active AUTP participant in Mempawah Regency. Determination of the number of respondents as many as 81 respondents. The results in this study are the level of motivation with a high category, the level of participation is included in the high category, the relationship between motivation and participation has a positive relationship, suggestions in research participants should be involved in the evaluation stage in order to contribute to providing criticism and suggestions
