Abstract

Industri  kelapa sawit menghasilkan  limbah cair yang dikenal  palm oil mill effluent (POME). POME memiliki kandungan BOD sebesar 230 mg/L dan COD sekitar 700 mg/L sehingga tidak dapat dibuang langsung ke lingkungan. Pengolahan yang umum dilakukan adalah pengolahan fisika dan biologi. Penelitian ini bertujuan untuk mempelajari proses pengolahan POME dengan menggunakan mikroalga liar, dimana dipelajari konsentrasi urea (N) dan ammonium bikarbonat (C). Respon yang diamati adalah konsentrasi biomassa sebagai optical density setiap harinya sampai diperoleh nilai konstan. Prosedur analisis dengan alat spektrofotometri. Limbah setelah operasi dianalisis nilai COD dan BOD Prosedur percobaan  yang dilakukan berupa pencampuran POME dan mikroalga kedalam bioreaktor sesuai perbandingan yang ditentukan. Hasil penelitian menunjukkan bahwa mikroalaga liar yang diperoleh di Jurusan Teknik Kimia FT UNDIP mampu mengolah POME, dimana  pengaruh pemberian  nutrient C dan N  terhadap COD dan BOD, bahwa semakin tinggi penambahan unsur C dan N semakin besar penurunan nilai COD dan BODnya. Kondisi optimum untuk pengolahan limbah industri kelapa sawit dengan teknologi mikroalga pada media perbandingan 1 volume mikroalga berbanding 3 volume POME dengan nutrient 40 ppm urea dan 120 ppm NaHCO3.   Kata kunci: POME, Mikroalga liar, BOD, COD, optical density

Abstract

In Indonesia, the potential demand for eggs was still high from time to time reaching 5.2 million tons in 2021, triggering every animal feed company to compete in providing the national demand for eggs. PT ABC was one of the animal feed mills that experienced a decline in market share of 1.92% in 2021. This paper aims to identify the factors influence product competitive advantage, analyze internal and external factors, and formulate strategies to increase market share. Data was analyzed using IFE, EFE, IE, and SWOT matrix and ended with QSPM to get priority strategies from December 2022 until January 2023. The highest competitive advantage factor at PT ABC was in the after-sales service to customers with the highest priority strategy for the development of products to increase market share was increasing feed production while maintaining quality and the market penetration strategy was strengthening cooperation with third parties to facilitate business. Two priority strategies could be implemented for PT ABC. First on the product development strategy to increase feed production while maintaining quality and strategy regarding market penetration was sales segmentation to retail traders and direct breeders. Keywords: after sales, eggs, feed production, qspm, swot
