Judul: Pengaruh beberapa teknik pelleting terhadap kualitas fisikokimia pelet
Abstrak: Pelet merupakan salah satu pengolahan pakan. Teknik pelleting dapat dibagi menjadi dua yaitu pelleting tanpa steaming dan pelleting steaming. Penambahan whey protein yang mengandung asam amino esensial yang baik untuk sintesis otot protein. Penelitian ini bertujuan untuk menganalisis teknik pelleting terbaik yang menghasilkan kualitas fisikokimia pelet. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan menggunakan 4 perlakuan pelleting suhu ruang,pelleting suhu 60 °C, pelleting suhu 100 °C, dan pelleting steaming 100 °C.Perlakuan diulang sebanyak 4 kali dan jika berbeda nyata akan dilakukan uji lanjutDuncan. Hasil penelitian menunjukkan bahwa beberapa teknik pelleting berbeda nyata pada (P<0,05) terhadap kualitas fisik pelet yaitu aktivitas air, kerapatan pemadatan tumpukan, pellet durability index. Hasil menujukkan sifat fisikokimia terbaik diperoleh pada perlakuan pelleting steaming dengan nilai pellet durabillty index terbaik dibandingkan dengan perlakuan lainnya yang dapat dilihat dari tampilan fisik pelet pada setiap perlakuan. Kualitas kimia pelet tidak berbeda pada setiap perlakuan. Penggunaan teknik pelleting steaming merupakan teknik yang paling baik menghasilkan kualitas fisikokimia pelet., Pellet is one of the feed processing. Pelleting techniques can be divided into two, namely pelleting without steaming and pelleting steaming. The addition of whey protein which contains essential amino acids that are good for muscle protein synthesis. This study aims to analyze the best pellet technique that produces the physicochemical quality of the pellets. This study used a completely randomized design (CRD) using 4 treatments for pellets at room temperature, pellets at 60 °C, pellets at 100 °C, and pellets at 100 °C steaming. The treatment was repeated 4 timesand if it was significantly different, Duncan's further test would be carried out. The results showed that several pellet techniques were significantly different (P<0.05) on the physical quality of pellets, namely air activity, compaction density, pellet resistance index. The results showed that the best physicochemical properties were obtained in the steaming pellet treatment with the best pellet durability index valuecompared to other treatments which could be seen from the physical appearance of the pellets in each treatment. The chemical quality of the pellets was different in each treatment. The use of pelleting steaming technique is the best technique to produce the physicochemical quality of pellets.

Judul: Penggunaan Perekat Bentonite dengan Level Berbeda pada Pelet Ransum Ayam Broiler
Abstrak: Penelitian ini dilakukan untuk mengkaji pengaruh penambahan level bentonite terhadap komponen proksimat dan sifat fisik pakan ayam bentuk pelet. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan 5 perlakuan dan 4 ulangan. Metode yang digunakan adalah Rancangan Acak Lengkap (RAL) yaitu: P0 (ransum basal), P1 (ransum basal + 2% bentonite), P2 (ransum basal + 4% bentonite), P3 (ransum basal + 6% bentonite), P4 (ransum basal + 8% bentonite). Variabel yang diamati adalah komponen proksimat dan sifat fisik pelet. Data dianalisis dengan analysis of variance (ANOVA) dan apabila hasil menunjukkan berbeda nyata maka dilanjutkan dengan uji Duncan. Hasil penelitian menunjukkan bahwa pemberian bentonite dapat mengubah komponen proksimat yaitu menurunkan kadar air dan meningkatkan kadar abu. Pemberian 2 − 4% bentonite berpengaruh nyata (P<0,05) terhadap kualitas fisik meliputi berat jenis, ketahanan, dan kekerasan pelet. Dapat disimpulkan bahwa penambahan bentonite menghasilkan sifat fisik terbaik pada level pemberian 2%., This research was intended to examine the effect of increasing bentonite levels on the proximate composition and physical properties of chicken feed pellets. This research was conducted by implementing a Completely Randomized Design (CRD) with 5 treatments and 4 replications. The method used in this research was Completely Randomized Design (CRD), specifically: P0 (basal ration), P1 (basal ration + 2% bentonite), P2 (basal ration + 4% bentonite), P3 (basal ration + 6% bentonite), P4 (basal ration + 8% bentonite). The variables observed were the proximate composition and physical properties of the pellets. Subsequently, the data were analyzed by utilizing analysis of variance (ANOVA) and would be continued with Duncan’s test if the results show a significant difference. The result showed that the bentonite could alter the proximate components by lowering the moisture content and increasing the ash content. The administration of 2 – 4% bentonite was able to provide a significant effect (P<0.05) on physical quality, including the density, durability, and hardness of the pellets. Therefore, it can be concluded that the bentonite addition was capable of producing the finest physical properties at the 2% level of administration.

Judul: Revisi Marga Maotia Wedd. (Urticacae) di Malesia
Abstrak: A taxonomic revision of genus Maozrtia in Malesia has been done. At present revision, 6 species are recognized namely M. ambigua, M. diversifolia, M. lanceolata, M. platistigma, M puya, and M. setosa. M ambigua is divided into 7 varieties, which one of the variety (i.e. var. tomentosa) n ew to science and another (i.e. var. grandifolia) is a new combination based on M. grandifolia. Two new varieties w i t h M. diversivolia (namely var. novoguinesis and var. suniatrana) are proposed. M. gracilis is recognized here as a synonim 0f M. lanceolata.
