Abstract

Pemalsuan lemak babi dalam minyak zaitun memiliki persentase tertinggi di antara minyak nabati lainnya. Hal ini berakibat buruk pada kesehatan seperti kolesterol dan resiko jantung koroner dan juga merupakan isu penting untuk mayoritas penduduk Indonesia yang beragama muslim. Oleh karena itu, pengembangan sistem deteksi kandungan babi dalam minyak zaitun sangat penting dilakukan. Metode deteksi berbasis Serat Optik Plastik Double Tapered (SOP DT) menawarkan keunggulan non destruktif, mudah dalam pemakaian dan instalasi, dan sensitivitas yang tinggi. Proses tapering menggunakan metode etsa kimia, serta sampel yang digunakan yaitu minyak zaitun dengan campuran 0-5% kandungan minyak babi (v/v). Pada pengujian spektrum didapatkan sensitivitas SOP DT dengan jarak antar tapered 1,2, dan 3 cm berturut-turut adalah 0,5 nm/%, 1 nm/%, dan 2,2 nm/%, yang mana lebih tinggi dari sensitivitas serat optik plastik Single Tapered (SOP ST) yang hanya mencapai 0.2 nm/%. Pada pengujian berbasis intensitas didapatkan sensitivitas SOP DT dengan jarak antar tapered 1,2, dan 3 cm berturut-turut adalah 1 dB/%, 1,02 dB/%, dan 1,42 dB/% yang mana lebih tinggi dari sensitivitas SOP ST yang hanya mencapai 0.85 dB/% pada penelitian sebelumnya. Limit of detection pada SOP DT yang terkecil didapatkan pada SOP DT dengan jarak antar tapered 3 cm, yaitu sebesar 0,25% dan 0,32% berturut-turut pada pengukuran berbasis spektrum dan intensitas. Selain itu, nilai Relative Standar Deviation (RSD) yang terkecil juga didapatkan pada SOP DT dengan jarak antar tapered 3 cm yaitu 0,0002 dan 1,09 × 10−6 berturut-turut pada pengukuran berbasis spektrum dan intensitas. Berdasarkan hasil yang didapatkan tersebut, dari ketiga variasi SOP DT yang telah difabrikasi, SOP DT dengan jarak antar tapered 3 cm memiliki performansi yang paling optimum.

Lard adulteration in olive oil has the highest percentage among other vegetable oils. This adulteration has negative health effects and also an important issue for the majority of the Indonesian Muslim population. Therefore, it is very important to develop a detection system for lard adulteration in olive oil. The Double Tapered Plastic Optical Fiber (DT POF) based detection method offers the advantages of non-destructive, easy to use and install, and high sensitivity. The tapering process uses a chemical etching method, and the sample used is olive oil with a mixture of 0-5% lard (v/v). Based on spectrum-based measurements, it was obtained that the sensitivity of the DT POF with distance between two tapered 1,2, and 3 cm are 0.5 nm/%, 1 nm/%, and 2.2 nm/% respectively, which is higher than the sensitivity of Single Tapered Plastic Optical Fiber (ST POF) that only reaches 0.2 nm/%. Based on intensity-based measurements, it was obtained that the sensitivity of DT POF with distance between two tapered 1, 2, and 3 cm are 1 dB/%, 1,02 dB/%, and 1,42 dB/% respectively, which is higher than the sensitivity of ST POF in previous study that only reaches 0,85 dBm/%. The smallest Limit of Detection was obtained in the DT POF with a distance between tapered of 3 cm, were 0.25% and 0.32%, respectively in spectrum and intensity-based measurement. In addition, the smallest value of Relative Standard Deviation (RSD) was also obtained in the DT POF structure with a distance between tapered of 3 cm, were 0.0002 and 1,09 × 10−6 on the spectrum and intensity-based measurements, respectively. Based on this result, from the three variation of DT POF structures that have been fabricated, the DT POF with a distance between tapered of 3 cm has the most optimum performance.
