Abstract

Kepuh (Sterculia foetida L.) merupakan tanaman non-pangan penghasil minyak yang bisa dijadikan bahan baku pembuatan biodiesel. Penelitian ini bertujuan untuk mengetahui karakteristik biji, kandungan minyak, hubungan kekerabatan dan kualitas biodiesel dari biji kepuh (Sterculia foetida L.) di Kabupaten Badung, Kota Denpasar dan Rote. Penelitian dilakukan pada Desember 2016 – Mei 2017. Metode yang digunakan adalah pengamatan terhadap karakteristik biji, menganalisis kandungan minyak dan kualitas biodiesel dari minyak kepuh (Sterculia foetida L.). Kandungan minyak tertinggi diperoleh dari Kabupaten Badung dan Kota Denpasar yaitu di Monang-Maning 1 sebesar 41,13%, sedangkan terendah dari Rote di Oemasi 4 sebesar 14,80%. Hubungan kekerabatan antara karakteristik biji dan kandungan minyak terbentuk 2 kelompok dengan indek similaritas 93,5%. Kualitas biodiesel di Kabupaten Badung dan Kota Denpasar memiliki angka asam yaitu 0,34 mg-KOH/g dan Rote yaitu 0,44 mg-KOH/g, angka iodin di Kabupaten Badung dan Kota Denpasar yaitu 44,41 dan Rote yaitu 48,53. Angka penyabunan di Kabupaten Badung dan Kota Denpasar yaitu 187,93 dan Rote yaitu 194,94, angka setana di Kabupaten Badung dan Kota Denpasar yaitu 64,02 dan Rote yaitu 61,92.

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

The aim of this study was to look at the effectiveness of organic fertilizers in increasing the production of anthurium sp flowers. Method of this research a randomized block design with 4 treatments and 6 replications. Starting with the manufacture of organic fertilizers by using chicken dung and waste cut flowers. Then made an application to the anthurium flowers. Parameters measured were plant height, number of leaves, number of tillers / hill, the amount of interest / clump and flower diameter. The results that the treatment significantly different (P <0.05) with the control. This suggests that organic fertilizers can increase production of cut flower anthurium sp, with the highest amount of interest and the interest of the longest diameter contained in the fertilizer treatment of 1.5 tons / ha. Number of tillers / clump and number of leaves contained in the fertilizer treatment of 2 tons / ha, this is due to the treatment, the number of N fertilizer is too high that the increased leaf production. From the results of this study concluded that organic fertilizers can increase production of flower anthurium sp.

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

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

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

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

Arenga palm (Arenga pinnata) is one species from palmae family. Economically, the palm is suitable for home industry, such as Balinese offering which use parts of young leaf, sap can be used as special local genius sweet drink from Bali, fruits are boilled that can be mixed with sugar for healthy ice. Arenga palm can be propagated aseptically using tissue culture technique. Culture media may varried between MS and WPM with or without adding hormone. Auxin can be added as 2.4-D ( 4 ppm) to induce callus. NAA and BAP with concentration 1.5 ppm respectively also added to induce multiplication of shoots or roots. Each treatment had 10 replicatations. Six weeks after cultured, callus growth observed only at WPM media that enriched with 2,4-D. The others treatment show the explant was dormant because did not show any growth while analysed anatomically under microscope.
