Abstract

One of the distillations of Lawang oil in the District of Elpaputih Bay still uses conventional methods. Therefore, through this activity a distillation process and analysis of the composition of Lawang oil (Cinnamomum sp.) was carried out using a modified distillation. Lawang oil (Cinnamomum sp.) was distilled using a steam distillation process with mace as a source of raw material. Content analysis was performed using GC-MS. From the results of the refining process with the modified refining model, an increase in yield of 47.2 % was obtained compared to the previous refining. Tests on the oil content of obtained show that the oil mostly contained eugenol, safrol, and 4-terpineol. Based on these results, it can be concluded that the modified refining tool has increased the yield of the oil produced. In addition, the compounds of the oil produced are identified.Keywords: Distillation, lawang, GC-MS. ABSTRAKSalah satu penyulingan minyak lawang di Kecamatan Teluk Elpaputih masih menggunakan metode konvensional. Oleh karena itu melalui kegiatan ini telah dilakukan proses penyulingan dan analisis komposisi minyak Lawang (Cinnamomum sp.) menggunakan penyulingan termodifikasi.  Minyak Lawang (Cinnamomum sp.) disuling menggunakan proses destilasi uap dengan kulit kayu lawang sebagai sumber bahan baku.  Analisis kandungan dilakukan dengan menggunakan GC-MS. Dari hasil proses penyulingan dengan model penyulingan termodifikasi diperoleh peningkatan rendemen sebesar 47,2% dibandingkan dengan penyulingan terdahulu. Uji terhadap kandungan minyak lawang yang diperoleh menunjukkan bahwa minyak tersebut sebagian besar mengandung eugenol, safrol, dan 4-terpineol. Berdasarkan hasil tersebut maka dapat disimpulkan bahwa alat penyulingan termodifikasi telah meningkatkan hasil minyak lawang yang diproduksi. Selain itu, senyawa penyusun minyak lawang yang dihasilkan telah diketahui.Kata kunci: Destilasi, lawang, GC-MS.

Abstract

Treatment for laboratorium waste need to carry out for prevented environment pollution if accumulation occured in the world. Natural resources available in maluku like clay can used to treat heavy metal Pb and Cu wastes. This adsorben were clay from Ouw village in Saparua,Maluku. The clay were brown and black. Each clay were activated with soaked in sulfuric acid for 5 and 10 hours. The result showed that the black clay with activated for 5 hours in sulfuric acid had the best adsorb.This clay more effective for adsorp Pb2+ ion compare with Cu2+ ion.Keywords : clay, adsorben, heavy metal.

Abstract

The silver nanoparticles (NPP) are synthesized with the chemical reduction method by using a water extract bioreductor of gandaria seed (Bouea macrophylla G.) which acts as a reducing precursor, in this case, AgNO3 Ag+ is reduced to AgO. The concentration of AgNO3 is made between 0.5 mm and 1 mm. The characteristic of NPP is unstable, so a modification is needed with and without the addition of PVA 1 %. The process of NPP shaping is monitored by observing the uptaken of UV - Vis when the color changes occur. The high NPP concentration of AgNO3 has higher absorbance and is wider if compared to the lower AgNO3 concentration. The result of this research based on the absorbance value and the wavelength showed the NPP synthesized without the addition of PVA 1 % (b/v) is wider. The addition of PVA 1 % (b/v) provides better stability and maintains the absorbance of spectrum changes from day to day. The maximum uptaken of UV-Vis from NPP AgNO3 0.5 mm by using green synthesis and 1 mm without adding PVA are 0.946 and 0.980, respectively. However, NPP with the addition of PVA has 0.968 and 0.978 absorbance. The best concentration of NPP produced was 1 mm AgNO3.
