One of the potential alternative feed ingredients as animal feed is water hyacinth. However, the low quality and palatability cause water hyacinth not being liked by ruminants. One way to improve the quality of water hyacinth is using controlled technology involving rumen microbes. The purpose of the study was to determine the level of addition of molasses and fermentation time in improving the quality of water hyacinth using rumen microbes through the test parameters for crude protein and crude fiber content. This study used a completely randomized design (CRD) with factorial patterns with molasses levels, namely M1 = 5%, M2 = 10%, M3 = 15%, and fermentation time consisting of T1 = 7 days, T2 = 10 days, T3 = 13 days . Each experimental design was repeated 3 times to form 27 experimental units. Data were analyzed using variance, if there was a significant treatment effect (P<0.05), followed by the HSD test on the average treatment. The results showed that the highest crude protein content was 14.23% in the M2T3 treatment (10% molasses level with 13 days of fermentation time) (P<0.05) while the lowest crude fiber was 14.55% in the M3T2 treatment (15% molasses level with a dangerous time) 10 days). This treatment was significantly different (P<0.05) from the other treatments. The results of the study concluded that the addition of 10% molasses for 13 days of brewing time could increase the crude protein content in water hyacinth fermented using rumen-filled microbes.and the lowest decrease in crude fiber was at 15% molasses level with 10 days of fermentation.

One of the keys to success in livestock farming is the provision of appropriate animal feed, especially goat farming. The feed ingredients for goats consist of forage in the form of fresh grass and silage, concentrate, supplementary feed and additional feed. The purpose of this activity is to increase knowledge about the management of goat feed for the recipients of goat livestock assistance from APBG funds in Alue Dawah Village, Babah Rot District, Southwest Aceh Regency. The method used in this service is the extension method, in the form of material exposure and introduction to the types of goat feed and management of feeding according to the life phases of goats, namely the growth, pregnancy and lactation phases. This activity was attended by 38 participants. Counseling is in the form of material presentation and introduction of forage forage, then followed by discussion or question and answer. The participants were able to understand how good goat feed management is and know the right way to cultivate goats.

ABSTRACT Herbal supplements are one of the products that are taken from outside the body derived from a mixture of herbal plant ingredients have antioxidant activity to prevent the presence of free radicals in the body. Testing natural antioxidant activity in herbal supplement products using the DPPH method (1,1-diphenyl-2-picrylhyrazil). Measurement of UV-Visible spectrophotometry absorbance with DPPH absorbance value at a wavelength of 517 nm. Sensory analysis using a hedonic test at the panelist preference level, using four attribute parameters namely taste, aroma, color and overall acceptance. Results Tests of antioxidant activity in herbal supplement products on various combination techniques and concentrations of garlic, ginger, local lemons and honey, resulting in the reduction of DPPH which is characterized by a reduction in the intensity of the color from purple to fade to yellow. Antioxidant testing obtained IC50 values ​​from all herbal supplement samples from various treatment techniques and concentrations showed IC50 values ​​less than 50 found in the treatment of chopped engineering materials, concentration 1 (K1) of 23.97%. While concentrations of 2 (k2) and 3 (k3) as well as in various combination techniques and other concentrations indicate that IC50 values ​​range from 50 ppm to 100 ppm. This shows that herbal supplements have very strong antioxidants (IC50 value <50) found in the treatment of ingredients with chopped techniques with the lowest concentration. whereas herbal supplements with treatment techniques and other concentrations have a strong antioxidant value of IC50 (50-100). The results of sensory analysis indicate that the average panelist had a preference level for herbal supplement products with chopping and extraction treatment techniques. Keywords: Antioxidant, DPPH, Herbal supplements, IC50   ABSTRAK   Suplemen herbal merupakan salah satu produk yang menjadi asupan dari luar tubuh yang berasal dari hasil campuran bahan tanaman herbal yang mempunyai aktivitas antioksidan tinggi untuk mencegah adanya radikal bebas dalam tubuh. Pengujian aktivitas antioksidan alami pada produk suplemen herbal menggunakan metode DPPH (1,1-diphenyl-2-picrylhyrazil). Pengukuran absorbansi secara spektrofotometri-UV Visibel dengan Nilai absorbansi DPPH pada panjang gelombang 517 nm. Analisis sensori dengan menggunakan uji hedonik pada tingkat kesukaan panelis, menggunakan empat parameter atribut yaitu rasa, aroma, warna dan penerimaan keseluruhan. Hasil Pengujian aktivitas antioksidan dalam produk suplemen herbal pada berbagai teknik kombinasi dan konsentrasi bawang putih, jahe, lemon lokal dan madu, menghasilkan peredaman DPPH yang ditandai dengan berkurangnya intensitas warna ungu menjadi pudar sampai kekuningan. Pengujian Antioksidan didapatkan Nilai IC50 dari seluruh sampel suplemen herbal dari berbagai teknik perlakuan dan konsentrasi menunjukkan nilai IC50 kurang dari 50 terdapat pada perlakuan bahan teknik rajangan, konsentrasi 1 (K1) sebesar 23,97 %. Sementara konsentrasi 2 (k2) dan 3 (k3) serta pada berbagai teknik kombinasi dan konsentrasi lainnya menunjukan bahwa nilai IC50  berkisar 50 ppm - 100 ppm. Hal ini menunjukkan bahwa suplemen herbal memiliki antioksidan yang sangat kuat (nilai IC50 <50) terdapat pada perlakuan bahan dengan teknik rajangan dengan konsentrasi yang paling rendah, sedangkan suplemen herbal dengan teknik perlakuan dan konsentrasi lain memiliki nilai antioksidan kuat IC50 (50-100) ppm. Hasil analisis sensori menunjukan bahwa rata-rata panelis memiliki tingkat kesukaan pada produk suplemen herbal dengan teknik perlakuan rajangan dan perlakuan sari.

ABSTRAKTongkol jagung merupakan bahan yang cukup potensial dimanfaatkan sebagai substrat sumber energi dalam memproduksi enzim selulase melalui proses fermentasi. Hal ini dapat dilihat dari  kandungan nilai gizi tongkol jangung sebagai berikut : 391 gr selulosa, 421 gr hemiselulosa, 91 gr lignin, dan 17 gr protein. Namun demikian selulosa dan hemiselulosa pada tongkol jagung belum optimal kerjanya dalam menginduksi produksi enzim selulase, karena rendahnya kandungan nitrogen sebagai pendukung pertumbuhan kapang. Blondo merupakan salah satu bahan yang dapat dijadikan sebagai substrat sumber nitrogen dalam medium fermentasi, karena kaya akan kandungan protein kasar sebanyak 24.22%. Penelitian ini bertujuan untuk mengetahui pengaruh komposisi substrat (tepung tongkol jagung (TTJ) dan blondo (B) dan lama fermentasi oleh Trichoderma Harzianum dalam memproduksi enzim selulase. Bahan utama yang digunakan dalam penelitian ini adalah tepung tongkol jagung, Blondo, PDA, isolat Trichoderma Harzianum, Reagen Nelson I dan Nelson II dan Fosfomolibdat. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) pola Faktorial 3 x 3 dengan 3 ulangan. Perlakuan yang diberikan yaitu komposisi substrat campuran tepung tongkol jangung (TTJ) dan blondo (B) dengan perlakuan B1 (80% TTJ+ 20% B), B2 (70% TTJ+ 30% B) dan B3 (60% TTJ+40% B) dan lama fermentasi (C) dengan perlakuan C1 (5 Hari), C2 (7 hari) dan C3 (9 hari). Data hasil penelitian dianalisis dengan menggunakan analisis ragam (ANOVA) dengan taraf signifikasi 5%. Variable yang diamati adalah aktivitas enzim selulase. Hasil penelitian menunjukkan bahwa perlakuan komposisi substrat 70% tongkol jagung dan 30% blondo dengan lama fermentasi 7 hari berpengaruh nyata (P<0.05) terhadap aktivitas enzim selulase.Kata Kunci : Tongkol jagung, blondo, Trichoderma harzianum, aktivitas enzim selulase
