Abstrak: The objective of this experiment was to evaluate storage wafer on physical characteristic and added water to increase acceptability of thin-tailed sheep. The experimental design used in this research was Completely Randomized Design for testing physical characteristic with 3 treatments and 3 replications with R1: 0 week storage, R2: 3 weeks of storage, R3: 6 weeks of storage and Block Randomized Design to test acceptability with 4 treatments and 3 replications with body weight as a block with P1: offering wafer without the addition of water, P2: offering wafer with the addition of water 25% of the feed given, P3: offering wafer with the addition of water 50% of the feed given, P4: offering wafer with the addition of water 75% of the feed given. The results of this research showed that the storage time significantly different (P<0.05) on moisture, water activity, water absorption. Insect attack can be increase with storage during six weeks. The Addition of water on wafer significantly different (P<0.05) on acceptability of sheep at length storage on 3 and 6 weeks. Based on the results length storage on 6 weeks increase on moisture, decrease on water absorption and increase on acceptability of sheep with the addition of water 75%.

Judul: Uji Sifat Fisik Wafer Limbah Sayuran Pasar dan Palatabilitasnya pada Ternak Domba
Abstrak: Vegetable waste is part of vegetables or vegetables that are discarded. The weakness of this vegetable market waste, among others, is perishable, voluminous (bulky) and the availability was fluctuated so the processing technology is needed to make this vegetable waste to be durable, easy to stored and to be given to dorbia. To solve this problem vegetable waste could be formed as wafer. The objective of this experiment was to determine the physical characteristic and palatability of vegetable market waste after formed as a wafer. The experimental design used in this research was Completely Randomized Design with 5 treatments and 4 replications. The treatments were : R1: maize straw 100%; R2: maize straw 75% + mungbeans sprout waste 25%; R3: maize straw 50% + mungbeans sprout waste 25% + cauliflowers 25%; R4: maize straw 25% + mungbeans sprout waste 50% + cauliflowers 25%; R5: maize straw 25% + mungbeans sprout waste 25% + cauliflowers 50%. Wafer’s variables measured were water activity, water absorption, density and palatability. The results of this research indicated that the treatment of wafer made from vegetable waste gave significant effect to the water activity (P<0.08) and wafer palatability (P<0.05). The highly significant effect (P<0.01) were from on water absorption and wafer density. Based on physical characteristic result of market vegetable waste wafer R1 have the highest water absorption. Wafer R5 gave a lowest water activity and wafer R3 gave a highest wafer density. The ration R4 was the most palatable compare to other treatments for the experimental sheep. Keywords : physical characteristic, wafer palatability, wafer and vegetable waste

Judul: Cycle Hamilton pada Graf Lengkap, Graf Regular, dan Graf 2-Connected 4-Regular Berorder Kurang dari Sepuluh
Abstrak: Suatu graf disebut graf Hamilton apabila graf tersebut memuat cycle Hamilton, yaitu cycle yang melewati setiap vertex tepat satu kali. Menentukan keberadaan cycle Hamilton pada suatu graf dapat menggunakan syarat cukup yang berupa teorema-teorema yang telah diperkenalkan sejak tahun 1950-an. Beberapa syarat cukup yang dibahas dalam karya ilmiah ini adalah syarat cukup yang berhubungan dengan graf lengkap dan graf regular. Suatu graf lengkap berorder 𝑛������ ≥ 3 dan graf r-regular berorder 𝑛������ ≤ 2𝑟������ + 1 merupakan graf Hamilton, Karena kedua graf tersebut memuat cycle Hamilton. Selanjutnya, syarat cukup tersebut digunakan untuk menentukan keberadaan cycle Hamilton pada graf 2-connected 4- regular berorder kurang dari 10.
