Citronella (Cymbopogon nardus L.) Oil Yield Analysis Planted with Agroforestry and Monoculture Patterns on Post-Coal Mining Revegetation Land

Abstract

Lemongrass (Cymbopogon nardus L.) is an economically valuable plant that produces citronella oil and could grow on marginal lands. This study aimed to analyze citronella oil yields planted with agroforestry and monoculture patterns in a post-mining revegetation area. The treatment consisted of 3 factors, namely planting pattern, fertilizer dosage, and plant spacing. The measured variable was the citronella oil yield. The study was conducted by planting two lemongrass varieties i.e., Sitrona 2 Agribun Variety dan G2 Variety in the agroforestry and monoculture areas. The study was conducted for 12 months with three harvest times, i.e., in the 6th, 9th, and 12th months. The results showed that planting patterns significantly affected the citronella oil yield. Planting pattern of Monoculture-Sitrona 2 Agribun Variety (P4) produced the highest oil yield (1,95%). Plant spacing and dosage of bokashi fertilizer did not significantly affect the citronella oil yield. The Monoculture-Sitrona 2 Agribun Variety (P4) significantly increased the oil yield compared to the Agroforestry- Sitrona 2 Agribun Variety (P2), Monoculture-G2 Variety (P3), and Agroforestry-G2 Variety (P1) with a respective oil yield of 1,95% (P4), 1,50% (P2), 1,01% (P3), and 0,99% (P1). Sitrona 2 Agribun Variety tended to produce a higher oil yield than the G2 Variety. Keywords: agroforestry, citronella oil, lemongrass, oil yield, revegetation

FORMULASI LILIN AROMATERAPI BERAROMA MINYAK SEREH WANGI (Cymbopogon nardus L.)

“…Minyak sereh wangi yang sudah didestilasi dilakukan pengujian terhadap bobot jenis kelarutan dalam etanol (SNI 06-3953-1995),, sitronelal (AOAC, 2016., dan rendemen (Juliarti et al, 2020). Selanjutnya lilin aroma terapi dilakukan pengujian sifai fisik dan organoleptik.…”

Sifat Antimikroba dan Pengaruh Perlakuan Bahan Baku terhadap Rendemen Minyak Sereh Wangi (Antimicrobial Properties and Effects of Raw Material Treatments on Citronella Oil Yield)

“…Sereh wangi merupakan salah satu hasil hutan bukan kayu (HHBK) yang disukai masyarakat untuk dibudidayakan karena bersifat ekonomis dan tidak membutuhkan biaya perawatan yang besar (Alam et al 2018). Tanaman sereh wangi dapat tumbuh di lahan subur maupun marginal, memiliki jumlah akar cukup padat dan kanopi cepat terbentuk (Juliarti et al 2020), ditinjau dari sisi konservasi tanah tanaman ini dapat mengurangi tanah tererosi serta mampu menjaga tingkat kadar hara tanah (Daswir 2016). Sereh wangi dapat ditanam secara tumpang sari atau mengikuti pola agroforestri.…”

“…Distilasi dihentikan setelah tidak ada penambahan minyak selama 30 menit di dalam oil trap. Penghitungan rendemen adalah sebagai berikut (Juliarti et al 2020):…”
