Abstract

Tumbuhan hijauan pakan merupakan salah satu faktor esensial dalam pengembangan usaha peternakan khususnya ternak ruminansia. Dalam hal ini dibutuhkan jumlah dan kualitas hijauan pakan tersedia cukup dan berla njut. Salah satu jenis hijauan pakan yang potensial adalah rumput gajah dwarf (Pennisetum purpureum cv. Mott). Salah satu masalah yang dihadapi dalam memperoduksi hijauan pakan adalah keterbatasan lahan. Namun demikian masih juga tersedia lahan perkebunan kelapa yang dapat digunakan namun dibutuhkan jenis hijauan yang toleran terhadap naungan dan produktif. Rumput gajah dwarf termasuk jenis dengan jalur metabolism C4 yang secara umum sensitive terhadap daungan. Namun demikian pemberian unsure makro nitrogen diharapkan dapat berinteraksi baik untuk menunjang produktifitas jenis rumput ini. Penelitian ini bertujuan untuk mengkaji interaksi level naungan dan level pupuk nitrogen terhadap karakteristik fotosintetik rumput uji ini. Perlakuan yang diuji adalah factor A level naungan : a1 = 0% naungan; a2 = 70% naungan. Level pupuk nitrogen sebagai factor B: b1 = 0% N; b2 = 92 N/Ha; b3 = 184 N/ha; b4 = 368 N/ha. Perlakuan diatur berfaktor dalam pola petak terpisah (split plot design). Data diolah menggunakan analisis keragaman dengan dituntun Program Minitab. Perbedaan antara perlakuan dilakukan uji lanjut Tukey. Hasil penelitian menunjukkan perlakuan naungan 70% berpengaruh nyata terhadap semua parameter yang diuji. Demikian juga level pemupukan nitrogen terutama berpengaruh nyata pada parameter kandungan klorofil b dan terhadap panjang daun, lebar daun, kandungan nitrogen dan protein. Berdasarkan hasil pembahasan dapat disimpulkan bahwa kendatipun dibawah pengaruh naungan tetapi karakter fotosintetik rumput gajah Dwarft (Pennisetum purpureum cv. Mott) dapat diperbaiki dengan penambahan unsur hara makro nitrogen.

Abstract

INFLUENCE OF CONCENTRATION AND SOAKING TIME OF A. pintoi IN THE COW URINE ON PLANT GROWTH. Cow urine has an auksin a, auksin b, and IAA (hetero auksin) that can stimulate plant roots. The present study was conducted to determine the influence of concentration and soaking time in the cow urine on Arachis pintoi (A. pinto) growth. This study used Completely Randomized Design (CRD) in Factorial arrangement with 2 factors A and B. Factor A= urine concentration: A1 = urine 75% + water 25% and A2; urine 50% + water 50%; and factor B = soaking time: B1 = 1 hour; B2 = 2 hours; Dan, B3 = 3 hours. Treatments were replicated 4 times. Parameters measured were: leaves amount (sheets), plant length (cm), and root weight (g). Research results showed that mean leaves amount ranged from 41,65 to 46,77 sheets, plant length 35,97-36,67 cm, and root weight 1,95-1,72 g. Utilization of cow urine with a different concentration and soaking time gave a non significant different (P>0.05) on leaves amount, plant length, and root weight. It can be concluded that cow urine concentration and soaking time do not effect leaves amount, plant length, and root weight of Arachis pintoi (A. pinto). Key words:  Cow urine concentration, Soaking time,  A. pintoi.

Abstract

THE EFFECTS OF OFFERING KING GRASS (Pennisetum purpupoides) AND CORN  STOVER ON DRY MATTER AND  ORGANIC MATTER OF ONGOLE CROSS BREED STEER CALVES. A research has been conducted to evaluate the effects of offering king grass (Pennisetum purpupoides) and corn stover as ingredients for ration formulating on dry matter and organic matter digestibility of ongole cross breed steer calves. Five ongole cross breed steer calves with about 100 kg body weight were used in this experiment. Latin square design  with 5 tereatments was used. The treatments were rasio of king grass and corn stover; R1 = 100% king grass, R2 = 75% king grass + 25% corn stover, R3 = 50% king grass + 50% corn stover, R4 = 25% king grass + 75% corn stover, R5 100% corn stover.  The variables measured were dry matter and organic matter digestibility. Analysis of variance showed that there were no significant effect of treatments on dry metter and organic matter digestibility. Averages of dry matter digestibility during experiment ranged 56.27% - 59.48%. The highest was 59.48% for R5 (100% corn stover) and the lowest was 56.27% for R1 (100% king grass). Averages of organic matter ranged from 87.64% to 88.72%. The highest organic matter digestibility was on R4 (25% king grass + 75% corn stover) and the lowest organic matter digestibility was on R2 (75% king grass + 25% corn stover). It can be concluded that the best nutritive value was at combination of 25% king grass + 75% corn stover on dry matter and organic matter digestibility of ongole cross breed steer calves. keywords: king grass, corn stover, digestibility, dry matter, organic matter
