    ABSTRAK Penelitian ini analisis kaidah muhkam dan mutasyabih dalam penafsiran QS. Al-A’raf oleh M. Quraish Shihab dalam Tafsir Al-Misbah. Latar belakang penelitian ini adalah bahwa ada kesalahan dalam penafsiran Al-Qur'an yang menyebabkan ajarannya digunakan dengan cara yang tidak sesuai dengan prinsip Islam. Oleh karena itu, pemahaman kaidah tafsir atau qawaid tafsir sangat penting sebelum menafsirkan Al-Qur'an. Penelitian ini menggunakan pendekatan kepustakaan kualitatif dan berfokus pada analisis ayat-ayat muhkam dan mutasyabih dalam surah Al-A’raf, terutama ayat 3, 54 dan 163-166. Hasil penelitian menunjukkan bahwa ayat muhkam QS. Al-A’raf ayat 3 memiliki makna yang jelas dan langsung, yaitu perintah untuk mengikuti wahyu Allah dan larangan untuk mengikuti selain-Nya. Sedangkan, ayat mutasyabih QS. Al-A’raf ayat 54, di sisi lain, memiliki makna yang tidak langsung dan memerlukan penafsiran yang lebih mendalam. Contohnya adalah yang disebutkan "bersemayam di atas "Arsy", yang secara harfiah tidak dapat dipahami. Menurut Tafsir Al-Misbah, unsur muhkam dan mutasyabih dapat muncul bersamaan dalam satu ayat, seperti yang terlihat dalam QS. Al-A’raf ayat 163-166, dalam ayat ini Allah memperingatkan kaum sabat yang melanggar syariat dan menunjukkan kekuatan-Nya untuk mengubah mereka menjadi kera. Oleh karena itu, pemahaman tentang kedua jenis ayat ini harus proporsional, dengan ayat muhkam diamalkan dan ayat mutasyabih diimani, dengan menggunakan pendekatan menyerahkan makna yang tidak jelas kepada Allah (Tafwidh), dan mencari makna yang lebih dalam (takwil). Kata Kunci: Qawa’id tafsir, Analisis, muhkam, mutasyabih, tasir al-Misba

    Over time, oil production in well “R” has decreased, currently well “R” has an actual flow rate of 490 BFPD with a water cut of 90%, consisting of an oil flow rate of 49 BOPD and a water flow rate of 441 BWPD, with the high water flow rate in this well, well “R” is indicated to be experiencing water coning problems. Water coning occurs when the actual production rate exceeds the critical production rate, which is the fluid production rate permitted by a well to be produced without coning, so that excessive production causes the flow pressure gradient to exceed the gravitational force, resulting in the penetration of the productive layer by water. The Chierici method is one method that can be used to calculate the critical production rate in the "R" well in order to determine whether the well being studied is experiencing water coning. The method used to overcome the water coning problem in this study is to reduce the flow rate by reducing the frequency on the Variable Speed Drive (VSD). Well “R” uses an artificial lif electric submersible pump with an actual production rate of 490 BFPD exceeding the critical production rate of 157.487 BFPD, so to overcome the water coning problem, the flow rate is reduced by reducing the pump frequency using a variable speed drive, the frequency recommended by the author is 19 Hz with a flow rate of 155.17 BFPD

    Fuel oil and gas in the coming years will still be the main energy source in supporting community activities. However, the increase in world oil prices led to an increase in fuel prices including gas and kerosene. One of the alternative energy sources that can be used is the use of wood waste as fuel for households or industries in the form of biomass pellets (pellets). The purpose of this study was to determine the quality of wood pellets from laban wood (Vitex pubescens) based on SNI 8021: 2014. This study used laban wood powder from the stems, branches and twigs, and tapioca flour as adhesives. The size of the powder used was 40 mesh stuck in 60 mesh. The pellet stamping used a pressure of 60 kg/cm3. The wood pellets tested included moisture content, density, volatile matter content, fixed carbon content, ash content, and calorific value. The test results showed that the stems of laban wood pellets produced better qualities than the branches and twigs parts although they were not significantly different. The range of laban wood pellets from the middle stems, branches and twigs were 11.27 ̶ 11.62% (moisture content), density were 0.34 ̶ 0.53 g/cm3, ash content were 0.83 ̶ 1,05%, volatile matter content were 71.20-72.00%, carbon content were 14.93-16.38%, and calorific value were 4486.46 ̶ 4514.46 cal/g. The test results were within the requirement of the Standards of Indonesia (SNI 8021-2014), the Korea Standard (KFS), and the Jeman Standard (DIN51371), except the density was not within the requirement of the SNI 8021-2014 Standard and the Jerman Standard (DIN51371). The density of the stem section was within the requirement of the Korean standard
