Abstract

Tetrigona apicalis were known as lebah penyengat and its can be produce propolis were extracted by metode shaking ultrasound-assisted extraction (SUAE), which produces perfect extraction, higher yield and active content, and a shorter time. The purpose of this research were fined the optimum conditions for extracted its by using the SUAE method in glycerol solvent. It were done to raw propolis with size reduced, then solvent was added and macerated using shaker. It was processed with a sonicator, than filtered. The solvent used  70% glycerol, and the results of the propolis extract are processed using Response Surface Methodology (RSM). The optimal conditions of its process from the yield response shown were a stirring time of 28.76 minutes and an ultrasonic process time of 23.94 minutes with a yield of 4.238%. Based on statistical analysis using Minitab Version 19 software, stirring time and ultrasonic processing time are factors that have a significant influence on the yield of propolis extract produced. The model used is a quadratic model with R2 0.9191. A quadratic equation model was obtained which states the relationship between propolis extract yield and the varied factors X = 0.865 + 0.0091A – 0.0186B – 0.000006A2 + 0.00370.B2  + 0.00215AB

Abstract

Benih adalah komponen utama dalam budidaya sehingga menjaga mutu dan kualitas benih merupakan hal yang sangat penting untuk dilakukan. Penggunaan minyak atsiri dari tanaman salah satu terobosan baru sebagai upaya untuk melindungi benih dari serangan hama Sitophilus zeamais dan mengurangi ketergantungan terhadap pestisida kimia. Penelitian ini bertujuan untuk menganalisis toksisitas ketiga minyak atsiri dan menguji pengaruh jenis serta dosis minyak atsiri terhadap viabilitas dan vigor benih jagung putih. Tahapan penelitian meliputi perbanyakan Sitophilus zeamais, ekstraksi minyak atsiri, pembuatan larutan emulsi, uji toksisitas terhadap Sitophilus zeamais, uji viabilitas dan vigor benih jagung putih. Data hasil penelitian uji toksisitas dianalisis menggunakan analisis PROBIT SPSS sedangkan data uji viabilitas dan vigor diolah menggunakan ANOVA dan uji lanjut BNT pada taraf 5%. Berdasarkan hasil analisis, toksisitas minyak atsiri biji pala lebih tinggi dari minyak atsiri temulawak dan serai wangi. Jenis dan dosis minyak atsiri berpengaruh terhadap viabilitas benih jagung putih. Penggunaan konsentrasi minyak atsiri biji pala, serai wangi, dan temulawak pada konsentrasi 0,1—0,4% menghasilkan viabilitas yang tidak berbeda. Penggunaan minyak atsiri berpengaruh terhadap vigor benih jagung putih. Pada konsentrasi 0,1% minyak atsiri temulawak menghasilkan panjang akar terbaik, sedangkan minyak atsiri serai wangi 0,1% menghasilkan tinggi tanaman terbaik.
