Abstract

Mixing different types of vegetable oils for synthesis of biodiesel is one of the efforts for renewable alternative energy. Mixed oil of vegetable oils more potential because it is not difficult to finding raw materials and not useful yet. Vegetable oils mixture as raw materials used include: Jatropha curcas oil, nyamplung oil and waste cooking oil. The mixed and optimized compositions use the simplex lattice design method with a total mixture. The data to be obtained is the influence data of each mixed oil to decrease of FFA during esterification reaction. Simplex lattice design method is one of the methods available in the software Design Expert 10.0. The designs used to optimize the formula on different amounts of different material compositions. The biodiesel synthesis is run based on the experimental design produced by the Expert Design 10.0 program. The use of lattice simplex method design: determination formula, optimizing formulation variable and total number of runs, keeping total concentration constant. ANOVA (Analysis of variance) to determine the significance of response analysis among variables and can know the suggested model. Desirability is a method that shows the program's ability to meet the criteria specified in the final product. The desired value that is critical to the desired product improvement program is so perfect.

Abstract

Indonesia sebagai negara agraris, sebagian penduduk Indonesia bermata pencaharian di bidang pertanian. Pada umumnya, masyarakat menggunakan pestisida untuk membasmi hama. Karena tingginya penggunaan pestisida maka WHO (2016) menyatakan kasus keracunan pestisida mencapai 193.000 jiwa selama tahun 2012. Untuk mengatasi permasalahan tersebut, biopestisida menjadi bahan alternatif pengganti pestisida karena lebih aman dan ramah lingkungan. Salah satu bahan alam yang berpotensi sebagai biopestisida adalah kulit durian. Rata- rata produksi durian setiap tahunnya 780.032,8 ton/tahun. Limbah kulit durian memiliki berat 60-75% dengan kandungan senyawa metabolit sekunder relatif tinggi belum termanfaatkan secara maksimal. Senyawa tersebut dimanfaatkan sebagai antioksidan dan antimikroba dalam proses pembasmi hama. Biopestisida yang dikembangkan dengan metode sokletasi menghasilkan ekstrak berbentuk cair. Namun, hasil tersebut kurang efektif dan mudah teroksidasi sehingga menurunkan keefektifitasan kadar bahan aktif. Mengatasi masalah tersebut maka perlu dikembangkan inovasi dengan proses enkapsulasi. Artikel ini me-review pengembangan metode enkapsulasi. Metode yang dapat digunakan untuk enkapsulasi biopestisida yaitu ekstrusi, spray chilling dan spray drying. Metode spray drying lebih berpotensi mengenkapsulasi biopestisida dari kulit durian karena memiliki efisiensi enkapsulan lebih tinggi dan hampir mendekati 100%. Distribusi ukuran partikel yang dihasilkan tergolong nanoenkapsulan. Indonesia as an agrarian country, most of Indonesia's people work in agriculture. In general, people use pesticides to eradicate pests. Due to the high use of pesticides, WHO (2016) stated the case of pesticide poisoning reach 193,000 in 2012. To solve the problem, Biopesticide as an alternative of synthetic pesticides because it’s more safe and environmentally friendly. One of the natural ingredients that potentially as biopesticide is durian peel. The average durian production per year is 780,032.8 tons/year. Durian peels waste weighs 60-75% with a relatively high contains of secondary metabolite not yet fully utilized. It’s used as antioxidants and antimicrobials in pesticides. Biopesticide is developed by socletation method. However, the results are less effective because it’s easily oxidized, so reduce the flavonoid efectiveness. To solve this problem, to be developed innovation with encapsulation process. This article reviews the development of encapsulation methods. Methods that can be used for biopesticide encapsulation are extrusion, spray chilling and spray drying. Spray drying method is more likely to encapsulate biopesticides because it has higher encapsulation efficiency and is close to 100%. The resulting particle size distribution is classified as nanocapsul.
