Abstract

The effect of temperature and length of storage on vitamin C concentration of chili (Capsicum frustescens) was observed on this study. Samples were taken from farmer’s field around Gianyar Regency of Bali. The chilies were treated with temperature such as 10ºC, 20ºC, and 29ºC (room temperature) and stored for 5, 10, and 15 days. Jacobs method was applied for vitamin C determination. The highest vitamin C content was obtain from control (59,9 mg/100 ml). On the other hand, the lowest was from chili that stored at room temperature for 15 days (23,6 mg/100 ml). For weight loss, the highest of loss was from chili which stored at room temperature for 15 days.

Abstract

The purpose of this study was to determine the effect of bioactive substances in the leaf extract of Piper caninum against rice blast disease caused by the fungus Pyricularia oryzae. This study was conducted in a greenhouse, using a completely randomized design. The results showed that the leaf extract of P. caninum formula can significantly suppress the intensity of blast disease in rice plants. The inhibition (90.51%) contained at a concentration of 2.5%. P. caninum leaf extract also significantly affect the growth and yield components. The concentration of 2.5% provides the highest grain yield (11.43 t/ha), while the extract 3.5% the intensity of the disease has increased and yield components decreased because the rice plants begin to experience toxic due to the concentration exceeding the limit too high extract optimal.

Abstract

Penelitian bertujuan untuk mengetahui jenis zat pewarna merah yang dominan dan kadar zat pewarna merah pada makanan yang beredar di Sekolah Dasar di Jimbaran. Penelitian dilakukan dari bulan Agustus-September 2012. Total jumlah sampel yang diambil adalah 16 sampel makanan yang berasal dari 8 sekolah yang mana 2 sampel diambil dari masing-masing makanan. Analisa dilakukan dengan 2 metode uji yaitu uji kualitatif untuk menentukan jenis pewarna dengan kertas kromatografi dan uji kuantitatif untuk menentukan kadar zat pewarna sintetis menggunakan metode spektrofotometri. Hasil penelitian menunjukkan bahwa terdapat 3 jenis zat pewarna makanan yang digunakan yaitu Rhodamin B, Allura Red dan Ponceau 4R. Kadar rata-rata pewarna tertinggi terdapat pada Ponceau 4R (10,046 ppm) dan terendah terdapat pada Allura Red (6,4456 ppm). Konsentrasi tersebut masih berada dibawah batas maksimum penggunaan pewarna makanan yang ditetapkan oleh pemerintah yaitu 70-300 ppm.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian aspartam terhadap panjang siklus estrus mencit betina dewasa. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 6 ulangan. Perlakuan P0 sebagai kontrol diberi aquades dan perlakuan P1, P2 dan P3 diberi aspartam dosis10 mg/kg bb; 15 mg/kg bb dan20 mg/kg bb. Aspartam diberikan setiap hari secara oral (gavage) selama 14 hari sebanyak 0,3 ml. Setelah 14 hari, apusan vagina dibuat setiap 8 jam dalam sehari selama dua kali siklus estrus. Variabel yang diamati adalah panjang waktu tiap fase dalam siklus estrus. Hasil analisis menggunakan Uji One Way Anova dan Uji Kruskal Wallis menunjukkan bahwa aspartam secara nyata (P<0,05) memperpanjang siklus estrus dengan peningkatan dosis yang diberikan.

Abstract

Blast disease is a disease that attacks rice plants. The control of this disease is still using a synthetic fungicide that is very harmful to the environment. The purpose of this research is to know the effect of the combination of Piper caninum leaf extract with compost to blast disease and rice plant growth. This research was conducted in vivo in the glasshouse of Senganan village, Penebel Tabanan. Bali. This study used a randomized block design. In this study, the extracts were combined with organic fertilizer which was made by biotechnology stater starmic ok. Fo = control (soil 100%). F1= (soil 90% + compost 10% + extract 0,5%) .F2 = (soil 80% + compost 20% + extract 1%) F3 = (soil 70% + 30% + extract 1.5%). F4 = (soil 60% + compost 40% + 2% extract), do repeat 4 times. The results show that the formulas F3 effectively reduce the intensity of blast disease by inhibition of 79.09%, significantly affect the number of rice leaves, and the number of rice tillers increases but in treatment, F4 decreased. The height of the rice plant from F1 to F4 decreases, it is great because it reduces the fall when the rice is fruitfull. This is due to the disruption of growth hormone by the extract.

Abstract

Fusarium oxysporum Schlecht et Fr. merupakan patogen tular tanah yang dapat menyebabkan layu fusarium pada cabai rawit. Penggunaan Fungi Mikoriza Arbuskula (FMA) sebagai simbion dapat meningkatkan ketahanan tanaman terhadap infeksi jamur pathogen F.oxysporum. Penelitian ini bertujuan untuk mengetahui pengaruh FMA sebagai biokontrol pertumbuhan tanaman cabai rawit terhadap infeksi F. oxysprum serta efektivitas pemberian FMA untuk menurunkan intensitas serangan penyakit layu fusarium. Bibit cabai rawit ditumbuhkan pada media tanah steril (kontrol negatif), tanah steril dan 10 ml patogen (kontrol positif), tanah steril dan FMA 100 g, FMA 100 g dan 10 ml patogen, tanah steril dan 200 g FMA, FMA 200 g dan 10 ml patogen, tanah steril dan 300 g FMA dan 10 ml patogen. Hasil penelitian menunjukkan bahwa pemberian 200 g spora FMA menunjukkan pengaruh berbeda nyata pada tinggi tanaman, jumlah daun, berat kering akar dan berat kering tajuk tanaman cabai rawit berumur tiga bulan. Sedangkan inokulasi 300 g FMA memberikan hasil terbaik pada buah cabai dan persentase kolonisasi FMA sebesar 84, 45%. Inokulasi 300 g FMA menurunkan infeksi F. oxysporum saat 30 Hari Setelah Tanam (HST) sebesar 3.36%. Kesimpulan dari riset ini menunjukkan inokulasi FMA Glomus spp. mampu meningkatkan tinggi tanaman, jumlah daun, berat kering akar dan berat kering tajuk, kecepatan berbunga dan ketahanan tanaman terhadap infeksi jamur F. oxysporum.

Abstract

Indonesia is a tropical country with an area of coconut plantation of 3.7 Ha. The fruits of this plant have been used as materials in the production of Virgin Coconut Oil (VCO). Such oil is known to contain higher Medium Chain Fatty Acid (MCFA) or Medium Chain Triglycerides (MCTs) than original frying oil. The MCTs of this oil is very useful to avoid obesity, to reduce total cholesterol as well as to function as anti-microbes. These have been considered as a cheap solution to solve health related problems. The main objective of this research was to produce VCO catalyzed by pure culture of Lactobacillus plantarum isolated from a commercial VCO (Vici’O) combined with enzymes extracted from pineapple fruits. The study was conducted at the laboratory of Microbiology, Faculty of Mathematics and Sciences, Udayana University. The study was started with isolation and identification of Lactobacillus sp. from a commercial VCO. The VCO production method combined the two starters of Lactobacillus isolates (at concentrations of 0 to 10% v/v) and pineapple juice with various volumes (0 to 60 mL). In the first stage of the project, 3 potential Lactobacilli isolates (Sp1, Sp2, and Sp3) were successfully isolated and were confirmed to be Lactobacillus sp. In the main experiment, combination of 10% v/v Lactobacillus starter and 60 mL pineapple juice produced the highest VCO yield (43,17% v/v) with improved organoleptic properties, lower water content, lower saphonification, and lower peroxide than that specified by SNI No 7381: 2008.

Abstract

This study aims to determine the selection of plants and nutrient content of plant species selected by Timor deer (Cervus timorensis). This research was conducted in Penangkaran Bangsing, Pupuan, Tabanan, Bali. Determination of the composition of plant species of Timor deer feed (C. timorensis) using the direct method. The species of plants eaten by Timor deer are identified to the species level. The nutrient content of crude protein is determined by Semi-micro Kjeldahl technique, energy content (GE) with Bomb calorimeter, Calcium (Ca) and Phosphorus (P) content by Atomic Absorption Spectrophotometer (ASS) technique. Selection of the plant species eaten using the Ivlev selection index. The nutrient content of plant species is eaten compared to the standard nutrient content for timor deer. The results of the study were 13 species of selected plants, namely Impreata cylindrica, Pennisetum purpureum, Panicum ranusum, Axonopus compressus, Panicum muticum, Spilatnhes paniculata, Mikania micrantha, Gliricidia sepium, Calliandra sp, Hibiscus rosa-sinensis, Sechium edule, Diplazium esculentum, Pogostemon auricularia. The crude protein content ranged from 9.30 - 31.18%, GE 2.724 – 4.446 kcal / g, Ca 0.02 - 0.84%, and P 0.32 to 3.01%. The nutrient content is eaten according to nutritional standards according to Tuckwell (2003). Keywords : timor deer (Cervus timorensis), selection of plant spesies, nutrient content
