Kualitas Fisik Biskuit Pakan yang Berbeda Bahan Penyusunya

This study aims to determine the physical quality (water content, water absorption, and density) of corn leaf biscuits and corn husk biscuits compared with field grass biscuits conducted in the Animal Feed laboratory and the Feed Quality Testing Laboratory of the Polytechnic of Agriculture Development Yogyakarta-Magelang. The study was conducted using a Completely Randomized Design (CRD) with 3 treatments and 6 replications, namely biscuits from field grass and 15% molasses as a control (P0), corn leaf biscuits and 15% molasses (P1) and biscuits from corn husk and molases 15% (P2). The results of P0, P1 and P2 were equally good, in the physical quality test of the absorption capacity and density of feed biscuits. The lowest water content (P<0.05) was found in corn husk biscuits (P2). It was concluded that the biscuits, corn leaves and corn husk produced the same physical quality of water absorption and feed biscuits density, except for the water content, namely corn husk biscuits (P2) had the lowest water content values ​​compared to corn leaf biscuits and field grass biscuits

Perubahan Kelembaban dan Kadar Air Teh Selama Penyimpanan pada Suhu dan Kemasan yang Berbeda

Tujuan dari penelitian ini adalah untuk mengetahui pengaruh pengemasan dan suhu penyimpanan terhadap kualitas teh hitam dan teh hijau. Kemasan yang digunakan untuk mengemas kedua teh ini adalah plastik bening, karung plastik, dan paper sack. Masing-masing teh dengan kemasan tersebut disimpan selama 10 minggu pada suhu 30oC dan 10oC. Variabel primer yang akan dianalisis adalah kelembaban dan kadar air teh pada beberapa jenis kemasan dan pada suhu penyimpanan yang berbeda. Berdasarkan hasil penelitian, diperoleh hasil bahwa selama penyimpanan, kadar air teh dalam kemasan bertambah karena pengaruh kelembaban udara dan suhu ruangan penyimpanan. Penyimpanan teh pada suhu 10oC dinilai lebih mampu mempertahankan kualitas teh hijau dan berpotensi mempertahankan kualitas teh hitam dibandingkan penyimpanan pada suhu 30oC. Dibandingkan dengan plastik bening dan karung plastik, kemasan paper sack merupakan kemasan yang berpotensi paling baik dalam mempertahankan kualitas teh hitam dan teh hijau. Semakin rendah permeabilitas suatu kemasan, maka semakin tinggi kemampuan kemasan mencegah peningkatan kadar air

Pengaruh Pupuk Urea terhadap Produksi dan Pertumbuhan Rumput Odot (Pennisetum purpureum cv Mott)

This study aims to determine the effect of 4 doses of urea fertilizer on production and growth of Odot grass (Pennisetum Purpureum cv. Mott). The experimental design used was a completely randomized design (CRD) pattern in line with 4 treatments and each treatment consisted of 5 replications. The treatment used is Control (P0), urea at a dose of 100 kg/ha (P1), urea at a dose of 150 kg/ha (P2), urea at a dose of 200 kg/ha (P3). The parameters observed were number of tillers, stem length, leaf length, grass height and grass production. The results of statistical analysis showed that the treatment of urea fertilizer had no significant effect on plant height. The treatment of urea fertilizer had a significant effect (P<0.05) on number of tillers, stem length, leaf length and grass production. It can be concluded that the administration of urea fertilizer can increase the number of tillers, stem length, leaf length and odot grass production compared to odot grass that is not given urea fertilizer.

COMPARISON OF VARIOUS FEED SAMPLES PREPARATION METHOD FOR IN VITRO GAS TEST

Fersh, freeze-dried and oven-dried samples of the leaves from seven plants species (Native grass, Imperata cylindrica, Pennisetum hybrid, Ceiba petandra, Musa sp, Leucaena leucocephala, and Dalbergia latifolia) taken from Yogyakarta, Indonesia were used to evaluate in vitro gas production in the absence or presence of polyethylene glycol (PEG). The nutritive value was assessed using the in vitro gas production technique after incubation for 3, 6, 12, 24, 48, 72, and 96h. The volume of gases produced from samples ranged from 25.33 to 68.51 ml in the absence of PEG, and from 29.38 to 75.99 ml in the presence of PEG. There was no responce of PEG for the grass. The fractional rate of gas production from samples that without or added with PEG varied between 1.10 to 4.80% and 1.20 to 4.80%, respectively. The mean value of gas production from fresh samples blend in 1 minutes and 2 minutes both higher significantly (P<0.05) than from freeze-dried and oven-dried samples. Fresh samples blended in 1 minutes produced a higher volume of gas than oven-dried samples but not significant. The mean value of gas production from samples that added with PEG higher significantly (P<0.05) than without PEG

Morfologi Telur dan Larva 2 Ascaridia Galli pada Ayam Kampung: Morfology of Ascaridia Galli Egg and Larvae 2 in Domestic Chickens

Ascaridia galli (A. galli) is a parasitic nematode that is often found in chickens which causes weight depression and retarded growth, reduced egg production and decreased egg quality. This study aims to determine the morphology of A. galli eggs and larvae 2 (L2) in domestic chickens. Worm eggs are obtained from adult worms that infect domestic chickens naturally. Larvae were obtained from culturing worm eggs in vitro at room temperature for 25 days. A total of 100 worm eggs and 10 L2 were used in this study. Egg measurements included length and width, while larvae included the total length of the larvae carried out with the Axiovision LE software from photographs taken using a light microscope. Data is processed using Microsoft Excel and is presented in the form of mean ± standard deviation and percent. Results obtained: egg length in this study was shorter than the results of previous studies and the morphology of larvae was the same as previous researchers.
