Abstract

ABSTRACTInterests on biochar application for the improvement of soil properties and fertily are increasing worldwide nowadays and numerous of production techniques are now available. This research was aimed at the investigation (a) on the characteristics biochar produced by 3 (three) different techniques, i.e: (1) traditional soil pit, (2) retort closed drum and (3) open drum kilns, as well as (b) on growth (height, leaf number and survival) response of Shorea leprosula seedling to 20%v biochar application on bioassay trial in the nursery. Bioassay trial was carried out in nursery of Forestry Faculty of Mulawarman University, Samarinda, Indonesia and was in accordance with Completely Randomized Design (CRD) applying 4 treatments and 3 replications.Of those 3 production techniques, retort closed drum kiln production technique was the most promising for further development and adoption providing not only that the biochar produced gave better properties and soil improvement capacity but also higher production recovery and less time and labour involvement. Furthermore, eventhough it was not statistically significant, biochar produced by retort closed drum gave better growth (height and leaf number) rate to S. leprosula seedlings in bioassay trial compared to those given by biochar produced by other techniques and without biochar treatments.

Abstract

Kegiatan pengabdian masyarakat di Kelurahan Mugirejo, Kota Samarinda, Provinsi Kalimantan Timur sebagai sentra produksi minyak atsiri memberikan peluang usaha produk turunan berbasis minyak atsiri. Salah satu minyak atsiri yang diunggulkan di Kelurahan Mugirejo adalah minyak serai dapur. Minyak atsiri serai dapur memiliki manfaat sebagai bahan baku eco enzyme. Masyarakat khususnya kelompok usaha tani Kelurahan Mugirejo belum mempunyai keahlian dalam mengembangkan produk turunan minyak atsiri. Pengabdian masyarakat ini bertujuan untuk pengembangan dan pemberdayaan masyarakat khususnya kelompok usaha tani melalui pembuatan produk turunan minyak atsiri, termasuk minyak atsiri serai dapur yang berupa produk eco enzyme. Program pengabdian masyarakat ini dilakukan dengan 3 tahapan yakni pelatihan pembuatan minyak atsiri dengan penggunaan teknologi penyulingan, pendampingan pembuatan eco enzyme serta kegiatan sosialisasi dan demonstrasi. Program pengembangan dan pemberdayaan produk eco enzyme berbasis minyak atsiri diharapkan dapat menjadi salah satu produk unggulan kelompok usaha tani Kelurahan Mugirejo untuk meningkatkan taraf kesejahteraan masyarakat Kelurahan Mugirejo.
