Ekstrak Virgin Coconut Oil Sebagai Sumber Pangan Fungsional

Virgin Coconut Oil (VCO) merupakan salah satu jenis minyak nabati yang dapat bermanfaat dari aspek medis dan nutrisi karena dapat mencegah dan membantu mengobati penyakit tertentu serta dapat mempermudah proses pencernaan makanan dan penyerapan gizi. VCO dapat bertindak sebagai antioksidan dan antifotooksidan yang disebabkan oleh kandungan komponen minor (mikronutrien). Tujuan penelitian ini adalah mengekstrak komponen minor VCO menjadi produk untuk pangan fungsional yang mampu berperan sebagai antioksidan dan mengetahui peran VCO sebagai antiradikal bebas secara in vitro. Penelitian ini menggunakan metode eksperimental dengan 3 tahap yaitu: 1. Ekstraksi VCO menggunakan pelarut etanol dan metanol, 2. Pengujian penangkapan radikal bebas ekstrak VCO secara in vitro dengan metode 1,1-difenil-2-pikrilhidrazil (DPPH), 3. Identifikasi dan pengujian komponen kimia pada ekstrak VCO, identifikasi dan pengujian komponen minor pada ekstrak VCO dengan menggunakan High Performance Liquid Chromatography (HPLC). Hasil penelitian ini menunjukkan bahwa rendemen ekstrak VCO semakin tinggi dengan semakin tingginya persentase pelarut, ekstraksi dengan menggunakan etanol menghasilkan rendemen ekstrak yang lebih tinggi dibanding dengan menggunakan metanol. Aktivitas antioksidan dan kandungan total tokoferol dari ekstrak VCO semakin tinggi dengan semakin tingginya persentase pelarut yang digunakan. Salah satu senyawa tokoferol yang terdapat dalam VCO adalah -tokoferol. Berdasarkan analisa statistik menunjukkan bahwa etanol dan metanol menghasilkan sifat kimia ekstrak yang relatif sama, sehingga dapat direkomendasikan bahwa untuk mengekstraksi komponen minor dari VCO dapat menggunakan etanol karena di samping aman dari aspek kesehatan juga dapat menghasilkan rendemen ekstrak yang lebih tinggi

Biomass Production and Formulation of Bacillus Subtilis for Biological Control

Bacillus subtilis is a widespread bacterium found in soil, water, and air. It controls the growth of certain harmful bacteria and fungi, presumably by competing for nutrients, growth sites on plants, and by directly colonizing and attaching to fungal pathogens. When applied to seeds, it colonizes the developing root system of the plants and continues to live on the root system and provides protection throughout the growing season. The study on biomass production and formulation of B. subtilis for biological control was conducted in the laboratory of Department of Plant Pathology, College of Agriculture, University of the Philippines Los Baños (UPLB-CA), College, Laguna from May to July 2005. The objective of the study was to determine the optimum pH and a good carbon source for biomass production of B. subtilis and to develop a seed treatment formulation of B. subtilis as biological control agent. Results showed that the optimum pH for growth of B. subtilis was pH 6 (1.85 x 109 cfu/ml). In laboratory tests for biomass production using cassava flour, corn flour, rice flour, and brown sugar as carbon sources, it grew best in brown sugar plus yeast extract medium (6.8 x 108 cfu ml-1 in sterile distilled water and 7.8 x 108 cfu ml-1 in coconut water). In test for bacterial biomass carriers, talc proved to be the best in terms of number of bacteria recovered from the seeds (3.98 x 105 cfu seed-1)

Analisis Produksi dan Pendapatan USAhatani Padi Sawah dengan Pola Tanam Tabela di Desa Dolago Kecamatan Parigi Selatan Kabupaten Parigi Moutong

The study aimed to determine the influence of land, seed, fertilizer, labor and income of direct seeding wetland rice farming system on its rice production in Dolago village, South Parigi subdistrict of Parigi Moutong District. The experiment was conducted from December 2015 to February 2016. The results showed that the land area (X1), the seeds (X2), fertilizers (X3) and the labor (X4) had simultaneously significant effect on the production of the direct seeding wetland rice farming system. This is indicated by the F-counted equal to 262.585> F-table 3.828 at α level of 1% suggesting the acceptance of H1. Partially the land area, the seeds, and the fertilizer are highly significant as shown by their t-counted of 8.35, 5.959, and 3.334, respectively are > t-table (2.423) at α level of 1% while the labor is significant (t-counted (2.235)> t-table (1.684) at α level of 5%. The average income of the respondent farmers is IDR 24,308,874.35/1.13 ha or IDR 21,449,006.79/ha

Alternative Control of Insect Pests in Vegetable Plants Using Local Wisdom Approach

This research aimed to determine the local wisdom of the community of Lembah Seulawah Sub-district, Aceh Besar, Indonesia of controlling insect pests in vegetable plants. In addition, the study intended to examine the impact of using paper as a mechanical trap for insect pests in vegetable plants. Both qualitative and quantitative methods were used in this research. The qualitative data were obtained through interviews with farmers, whereas the quantitative data were collected from an experiment. Thirty randomly-selected respondents were interviewed and then the qualitative and quantitative data processing was performed. The results showed that they still use plant-based materials as insecticides which constitute the local wisdom of controlling insect pests in vegetable plants. The plants used as insecticides were, among others, garlic (Allium satifum), castor bean seeds (Ricinus communis), lemongrass, neem seeds, and thorny amaranth as the trap plants

Biological Control of Banded Leaf and Sheath Blight Disease (Rhizoctonia Solani Kuhn) in Corn with Formulated Bacillus Subtilis Br23

Rhizoctonia solani Kuhn. causing banded leaf and sheath blight diseases is one of the important fungi of corn world wide. The fungus is commonly controlled by using fungicide because no resistant variety available. The objective of the study was to develop a seed treatment formulation of the selected Bacillus subtilis to control R. solani in corn. The study was conducted in the Department of Plant Pathology, College of Agriculture, University of the Philippines Los Bañòs, College, Laguna from May 2004 to August 2005, using sweet corn var. IPB Supersweet as test plant. Corn seeds were surface sterilized for 10 minutes in 1% sodium hypochlorite solution and 5% ethanol, washed thrice with sterile distilled water and air-dried. The seeds were coated with formulated B. subtilis BR23 and used for several experiments, such as evaluation for their germination and growth in the laboratory, effectively on R. solani in the baked and nonbaked field soil under greenhouse condition, and in the microplots artificially infested with R. solani. The treatment was compared with other standard seed treatment of synthetic fungicides such as captan (10 g per kg seeds) and metalaxyl (10 g per kg seeds). The experiments were designed in a completely random design with three replications. Parameters observed were seed germination, plant height, disease scores, and plant yield. Laboratory formulated B. subtilis BR23 used as seed treatment had no detrimental effects on seed germination and seedling vigor. In microplots artificially infested with a selected highly virulent R. solani, seed treatment with the same formulation increased grain yield by 27% compared to that of the control captan seed treatment with 14.4%. The studies showed the potential of B. subtilis BR23 for commercialization as a seed treatment for the control of banded leaf and sheath blight disease (R. solani) in corn
