Abstract

Limbah organik dari hasil pengolahan sayur dan buah-buahan merupakan limbah yang ditemukan sehari-hari. Umumnya limbah organik tersebut tidak melalui proses pengolahan terlebih dahulu, sehingga tidak menghasilkan nilai tambah. Pada dasarnya, limbah organik dapat dimanfaatkan sebagai bahan dasar pembuatan produk lain dengan nilai ekonomi yang tinggi seperti pupuk kompos. Pupuk kompos merupakan pupuk berbahan dasar organik dengan bahan dasar seperti sayur, daun, buah-buahan, dan bahan-bahan organik lainnya. Pupuk kompos memiliki sejumlah fungsi penting dalam proses perbaikan tekstur dan struktur lahan seperti peningkatan aerasi dan drainase, sehingga meminimalisir terjadinya erosi tanah. Peralatan yang digunakan dalam pembuatan kompos antara lain adalah pencacah sampah, gembor, sapu, karung, sekop, terpal, dan alat penggaruk. Adapun bahan dari pembuatan kompos antara lain adalah sampah organik, larutan berisi mikroba (EM-4), air dan tanah. Untuk menghasilkan kompos, diperlukan sebuah biodekomposer atau aktivator yang digunakan untuk meningkatkan laju proses pengomposan yang membutuhkan waktu setidaknya 1 bulan. Pada tahap akhir pembuatan kompos, terjadi perubahan warna sampah dari hijau ke coklat kehitaman yang menandakan bahwa kompos telah siap untuk dimanfaatkan. Pembuatan kompos terbukti dapat meningkatkan pemanfaatan sampah, seraya menjadi solusi terhadap permasalahan lingkungan. Kemampuan untuk mengolah sampah menjadi kompos ini dapat menjadi komoditas bernilai tambah dan memberikan dampak ekonomi yang positif bagi masyarakat.

Abstract

Friction is one of the unavoidable factors during drilling. If not properly managed, it can significantly reduce the rate of penetration (ROP), especially in horizontal wells. This research aims to examine the effectiveness of the Friction Reduction Tool (FRT) in managing friction without causing damage to the formation. The FRT is designed to reduce friction between the drill string and the wellbore by minimizing contact. However, its performance is often influenced by two main factors: formation characteristics and drilling parameters. This study analyzes Well X-4, which was drilled without FRT, and Well X-5, which was drilled with FRT from a depth of 2837 m (MD). The analysis focuses on the tool’s impact on stick-slip issues, ROP, and mechanical specific energy (MSE). The results indicate that the use of FRT reduced stick-slip levels and MSE, enabling the drill bit to penetrate the formation more easily. Additionally, activating the FRT from the start increased the penetration rate by 18% compared to drilling without it. These findings suggest that the FRT effectively enhances the drilling rate while preserving the formation integrity.

Abstract

Polymer injection is one of the EOR methods using chemical which is injected into the reservoir to increase oil recovery. The polymer functions to maintain the flow of fluids, especially water, so that it does not boil ahead of oil towards production wells. This is due to the ability of the polymer to increase the viscosity of the fluid in the reservoir. The polymers commonly used in the petroleum world are synthetic polymers and natural polymers which are often referred to as biopolymers. The type of biopolymer in this article is Xanthan Gum while the synthetic polymer used is Terrafloc. The characteristics of these two polymers are compared so that the performance that will be obtained in an effort to increase the recovery of petroleum can be estimated. From the results of the viscosity measurement, it turned out that the Xanthan Gum polymer had a much greater viscosity value than the Terrafloc polymer. Thus, the use of Xanthan Gum and Terrafloc polymers can be adjusted to the needs related to the type of crude oil in the reservoir to be injected so that the results of obtaining petroleum can be optimal.
