Red ginger essential oil is one commodity from the cultivation of red ginger. These types of oils obtained by distillation of red ginger have old after 10 months to 1 year cultivation. This study aimed to determine the effect of raw materials conditioning to the yield and quality of essential oils produced. The raw materials conditioning red ginger is done with two levels i.e fresh red ginger and air-dried red ginger about 24 hours under 2 repeated. The results showed that the yield of essential oil obtained by distillation of fresh red gingerwas 0.0705%, while the yield on the distillation of air- dried red was ginger 0.0435%. Refractive index value of red ginger essential oil from fresh material was 1.4885 while the refractive index of air-dried red ginger driedwas 1.4885. Furthermore, the specific grafity of at the distillation of fresh red ginger obtained at 0.90423 and the specific gravity of red ginger essential oil is dried at 0.89679. Solubility in alcohol red ginger essential oil of fresh and dried red gingerwere clearly at a ratio of 1: 5.

Abstrak.Menganalisis mutu selama penyimpanan dapat dilakukan dengan mengendalikan kondisi penyimpanan tertentu serta menduga laju penurunan mutu yang terjadi. Penelitian ini bertujuan untuk menduga umur simpan jeruk siam berdasarkan laju penurunan vitamin C selama penyimpanan menggunakan persamaan Arrhenius. Jeruk siam segar disimpan dengan variasi suhu yaitu suhu 10⁰C, 15⁰C, dan 28⁰C. Analisis dilakukan 3 hari sekali hingga panelis menolak dengan parameter susut bobot, tingkat kekerasan, total padatan terlarut (TPT), vitamin C, dan uji organoleptik yaitu warna, aroma, tekstur, rasa, dan penerimaan keseluruhan. Hasil penelitian diperoleh persentase susut bobot pada suhu 10⁰C dan suhu 15⁰C yaitu 11,57 % pada penyimpanan hari ke- 12. Tingkat kekerasan tertinggi pada suhu penyimpanan 10 ⁰C yaitu 2,09 Kg/cm2. Suhu 15 ⁰C mengalami kenaikan total padatan terlarut paling tinggi hingga 9,70% brix. Uji organoleptik penyimpanan terbaik pada suhu 15 ⁰C dengan lama penyimpanan hingga hari ke- 12, warna, tekstur, aroma, rasa dan penerimaan keseluruhan skornya yaitu 4,28, 4,05, 3,76, 4,50 dan 4,10. Umur simpan jeruk siam pada suhu 10⁰C umur simpannya 15 hari, suhu penyimpanan 15⁰C umur simpannya 14 hari, Suhu 28⁰C umur simpannya 13 hari. Penelitian ini didapatkan model pendugaan laju penurunan mutu jeruk siam selama penyimpanan yaitu k = 30.01808 e-777.54(1/T). Abstract. Analyzing the quality during storage could be done by controlling the storage as well as suspecting the rate of decrease the quality. This research aim to presume the life of siamese orange based on the rate of vitamin C decrease during the storage by using Arrhenius equation. The fresh siamese oranges with variety of storage temperature were 10 0C, 15 0C, and 28 0C. Analysis done in 3 days until the panelist refected to the shrinkage of weight, the level of solid, total soluble solid (TSS), Vitanin C, and organoleptic test such as colour, aroma, texture, taste, acceptance in a whole. From the result it is obtained the percentage of shrinkage weigh of temperature at 10 0C and at 15 0C was 11,57 % in the storage of day 12. The highest level of solid was on temperature at 10 0C was 2,09 kg/cm2. On the temperature 15 0C it has the total soluble solid up to 9,70b% brix. The best organoleptic test storage was on temperature 15 0C with in 12 days of storage, the highest colour, aroma, texture, taste, and acceptance in a whole score was 4,28, 4,05, 3,76, 4,50 and 4,10. The siamese orange life storage on temperature 10 0C could be storage for 15 days, on temperature 15 0C could be storage for 14 days, on temperature 28 0C could be storage for 13 days. The reseach found out that the persume of decreasing the quality of siamese orange duringstorage was k = 30.01808 e-777.54(1/T).

Penelitian ini dilakukan di Laboratorium Lapangan Peternakan (LLP), Fakultas Pertanian, Universitas Syiah Kuala, tanggal 7 Januari‒16 Maret 2016. Penelitian ini menggunakan 64 ekor DOC ayam kamaras. Perlakuan yang dicobakan adalah ransum komersil broiler 512 Bravo yang disubtitusi dengan tepung ampas tahu + tepung kulit telur + feed supplement sebanyak 0% (P1), 5%+1%+1% (P2), 10%+2%+1% (P3), dan 15%+3%+1% (P4). Parameter yang diamati adalah berat badan akhir, total konsumsi ransum, Income over Feed Cost (IOFC) dan total income. Hasil penelitian memperlihatkan bahwa meskipun secara statistik perbedaannya tidak nyata (P0,05), substitusi ransum komersil broiler (512 Bravo) dengan tepung ampas tahu sampai 15% + tepung kulit telur 3% + feed supplement 1% meningkatkan berat badan akhir dan konsumsi ransum ayam kamaras, menurunkan biaya variabel ransum, dan total biaya, dan meningkatkan Income over Feed Cost (IOFC) dan total income pemeliharaan ayam kamaras. Substitusi ransum komersil broiler (512 Bravo) dengan tepung ampas tahu sampai 15% + tepung kulit telur 3% + feed supplement 1% layak dan menguntungkan dalam pemeliharaan ayam kamaras.

The research was conducted at the Field Lab, Department of Animal Husbandry, Agricultural Faculty, Syiah Kuala University, January 7 to March 16, 2016. The study used 64 DOC of male kamaras chickens. The treatment tested was feeding male kamaras chickens with broiler commercial rations substituted by tofu waste meal + egg shell meal + feed supplement as much as 0% (P1), 5%+1%+1% (P2), 10%+2%+1% (P3), and 15%+3%+1% (P4), respectively. Parameters measured were final body weight (FBW), total feed consumption (TFC), and Income Over Feed Cost (IOFC) as well as total income. The results of study showed that although statistically no significant effects were detected (P0.05), using tofu waste meal up to 15% + egg shell meal 3% + feed supplement 1% as a partial substitution of broiler commercial rations tended to increase final body weight and total feed consumption of male kamaras chickens. Administration of these meal mixes was profitable, reduced cost and increased Income over Feed Cost (IOFC), and total income in raising of male kamaras chickens

Effect of Combination and Varieties Growing Media on the Growth and Crop Tomato (Lycopersicum esculentum Mill) in hydroponic substrate. This study aims to determine the best combination and variety of growing media on growth and yield of tomato plants in hydroponic substrate. Research conducted at the Experimental Farm, Faculty of Agriculture, University of Syiah Kuala, which lasted from January to May 2014. This study used a randomized block design 3 x 3 factorial design with three replications. This study consisted of two factors, the first factor is the combination of growing media consisting of a combination of sand + rice husk, sand + sawdust, sand + coconut coir. The second factor is composed of tomato varieties Hybrid varieties (Peto-seed), Superior (Ratna) and Local (Ground). Parameters measured were plant height and trunk diameter respectively at 15, 30, and 45 days after plant (HST), the number of flower planting age of 60, 67, 74, 81 and 88 days after planting, as well as the number of total fruit and total weight of the fruit planting. The results showed that growing media very significant effect on the diameter of the stem ages of 15 and 30 DAT, the number of flower planting age of 60, 67, 74, 81 and 88 days after planting, the number of total fruit crop and the weight of total fruit crop, significantly affected plant height age 15 and 30 DAT, and diameter at base age 45 HST. But no real effect on the plant height age of 45 HST. The growth and yield of tomato plants best seen in medium sand + husk. Varieties very significant effect on the amount of interest the age of 67 and 81 days after planting, the total number of fruit crops and fruit weight total crop. But no real effect on plant height and diameter at base age of 15, 30 and 45 days after planting. Growth and yield of tomato plants best seen in hybrid varieties (Peto-sedd). There is a very real interaction between the growing media and varieties of the total number of fruit crops and no real effect on other variables. Best interaction that combined treatment of the planting medium sand + rice husk and hybrid varieties (Peto-sedd).Keywords: tomatoes, Growing Media, varieties, hydroponic substrate.
