Abstract

This study was aimed to evaluate the effect of dietary energy level on daily gain of Madura cattle and their blood metabolites (glucose and blood urea). Twelve (12) male Madura cattle aged at 2 years old, 156.27+6.92 kg (CV 4.43%) of body weight were used in this study which was assigned to completely randomized design for three feeding treatments (low, middle and high energy contents) and four replications. The daily gain was measured for 90 days, while the blood metabolites were measured at the middle of experiment. Results showed that dietary energy levels did not affect (P>0.05) average daily gain, dry matter intake, dry matter digestibility, energy intake and feed conversion ratio. Blood glucose and blood urea concentration were ranged at 67-75 and 35-50 mg/dL, respectively, while feed energy efficiency reached 0.145 MJ/g ADG. In conclusion, high-level energy could not provide better performance in Madura cattle because of a limitation factor on the DMI.

Abstract

Each four young bulls of Madura cattle and Ongole Crossbred (OC) cattle were used to study theefficiency of ruminal fermentation by comparing the proportion of Volatile Fatty Acid (VFA) of thesetwo breeds which were raised under intensive feeding. All the cattle were in about 1.5 years-old with anaverage body weight of 147.75 ± 14.57 kg and 167 ± 22.57 kg, for Madura and OC cattle, respectively.They were fed Napier grass (Pennisetum purpureum) hay, and concentrate feeding consists of pollard,soybean meal and rice bran for 10 weeks. Parameters measured were concentration of VFA at 0, 3 and 6h post-feeding and pH. The concentration of VFA in both Madura and OC cattle was peaked at 3 h postfeeding,being 136.1 mmol and 158.9 mmol, respectively, and then were decreased at 6 h post-feeding ata level of 58.1 and 98.2 mmol, respectively. The proportion of acetic acid in Madura and OC cattle were53.33% and 52.0% of total VFA, respectively, while the proportion of propionic acid and butyric acidwere 28.80% and 17.87% for Madura cattle, and 30.71% and 17.28% for OC cattle, respectively. Inaddition, the Acetic/Propionic ratios were 1.85 and 1.69 for Madura and OC cattle, respectively. RumenpH conditions of both cattle breeds tended to be basic, i.e. Madura cattle was ranged at 8.0-8.4, while thePO cattle was ranged at 7.6-8.4. In conclusion, both cattle breeds (Madura and OC cattle) have a similarefficiency to utilize the feeds in the rumen.

Abstract

Pengelolaan inventori alat-alat di PT. Rotary Electrical Machine Service atau fasilitas lainnya membutuhkan sistem yang efisien untuk memastikan ketersediaan peralatan yang dibutuhkan. Penelitian ini bertujuan untuk merancang dan membangun sebuah sistem manajemen inventori berbasis web yang dapat membantu pengelolaan inventori alat-alat. Sistem ini dirancang untuk mencakup fitur-fitur seperti pencatatan stok, pelacakan riwayat penggunaan, dan pelaporan inventori, Metodologi penelitian yang digunakan adalah model waterfall, yang mencakup tahap analisis kebutuhan, perancangan sistem, implementasi, pengujian, dan deployment. Sistem dibangun menggunakan framework PHP dan database MySQL. Pengujian sistem dilakukan dengan metode black box dan kuisioner untuk menilai aspek usability.Hasil penelitian menunjukkan bahwa sistem manajemen inventori berbasis web yang dikembangkan dapat membantu PT. Rotary Electrical Machine Service atau fasilitas dalam mengelola inventori alatalat perusahaan secara efektif dan efisien. Sistem ini terbukti mampu meningkatkan akurasi data, mempermudah proses pencatatan dan pelaporan, serta membantu memonitor kondisi peralatan secara real-time. Pengguna juga memberikan umpan balik positif terkait kemudahan penggunaan dan manfaat sistem bagi pengelolaan inventori.
