Abstract

Proteins from animal sources are higher biological value than from plant sources, because animal proteins contain amino acids that more similar to our body’s need, however animal meats often contain high levels of saturated fats and cholesterol that increase the risk of heart disease. Differ to many land animals that contain high levels of saturated fatty acids, buffalo meat contains less saturated fatty acids, cholesterol and calories but higher in iron, vitamin B12 and protein than those of beef, pig  and skinless chicken. Grass-fed animals contain higher omega-3 fatty acid, lower ratio of omega-6 and omega-3 and higher content of conjugated linoleic acid (CLA) than those of grain-fed animals.

Abstract

Abstrak Tujuan dari penelian ini adalah untuk mengetahui cara penerapan metode Statistical Process Control (SPC) yang nantinya ditujukan untuk mengetahui penyebab mampu terka terhadap kecacatan produksi galvalum tipe reng kanal u yang akan dipecahkan permasalahannya menggunakan alat-alat SPC (7 tools). Data yang dibuthkan dalam penelitian ini adalah data sekunder kecacatan selama 8 bulan produksi dimulai pada bulan Agustus 2017 hingga Maret 2018. Alat-alat yang digunakan pada metode SPC ini meliputi histogram, diagram pareto, peta kendali, diagram sebab akibat, diagram tebar, lembar pengecekan dan flowchart. Alat-alat tersebut lebih sering disebut dengan 7 tools. Hasil dari analisis yang dilakukan menggunakan metode SPC memberikan hasil berupa penurunan kecacatan terhadap karakteristik ukuran tidak sesuai sebanyak 284 buah dan koil terlilit sebesar 248 buah. Penurunan tersebut disebabkan dengan mengatur ulang nilai set up time mesin roll forming menjadi 1600 menit per-pekan. Kata Kunci: Statistical Process Control, Galvalum, Reng Kanal U, Kecacatan, Set Up Time Abstract The purpose of this study is to know how to apply the Statistical Process Control (SPC) method which will be aimed to find out the cause of the defect of galvalume disability that can be solved by SPC tools (7 tools). Data used in this research is secondary data of disability during 8 months of production starting from August 2017 until March 2018. The tools used in this SPC method include histogram, pareto diagram, control chart, cause diagram, stocking diagram, check sheet and flowchart. These tools are more commonly referred to as 7 tools. The result of the analysis using SPC method gives the result of the decrease of defect to the unsuitable size characteristics as much as 284 pieces and the twisted coil of 248 pieces. The decline is caused by rearranging the set up time of the roll forming machine to 1600 minutes per week.Keywords: Statistical Process Control, Galvalume, U Type of Galvalume, Defect, Set Up Time

Abstract

Pengaruh skarifikasi dengan air panas, mekanik dan asam terhadap kemunculan bibit dan pertumbuhan awal lamtoro (Leucaena leucocephala) diteliti. Hasil berbagai metoda skarifikasi biji  menunjukkan bahwa semua metoda skarifikasi yang digunakan memperbaiki kemunculan dan pertumbuhan awal  Lamtoro. Perendaman biji di dalam asam sulfat selama 20 dan 24 menit menghasilkan persentase kemunculan bibit, tinggi tanaman, jumlah daun, biomassa bahan kering tertinggi dan indeks kemunculan bibit terendah, disusul dengan skarifikasi mekanik dengan pemotongan biji pada bagian mikropil dan perlakuan air panas temperatur 80o C selama dua menit. Kemunculan bibit dan pertumbuhan awal Lamtoro terendah diperoleh pada kontrol. Dapat disimpulkan bahwa skarifikasi biji dibutuhkan untuk memperbaiki kemunculan dan pertumbuhan awal bibit Lamtoro dengan skarifikasi asam merupakan metode terbaik, walaupun dari sudut pandang petani, karena kesulitan penanganan dan biaya yan tinggi mungkin bukan merupakan metode terbaik.

Abstract

The objectives of this experiment to determine dry matter yield, biological compatibility and  quality of guinea grass (Panicum maximum)- centro (Centrosema pubescens) mixtures planted at different population. Population of guinea grass planted were 4, 3, 2, 1 and 0 plants/pot combined with 0, 1, 2, 3, 4 and 0  of centro/pot. The plants were fertilized with phosphate fertilizer at the doses of 0, 100 and 200 kg P2O5/ha and harvested at interval of 30, 45 and 90 days. Results of experiment showed that dry matter yields of mixed plant were higher than those of guinea grass or centro planted as monoculture. Guinea grass was compatible when planted with centro because their relative yield totals > 1. With increasing centro planting population and decreasing harvest interval,  relative feed value and relative forage quality increased. Based on fibre content and quality, the quality of guniea grass and centro, both planted as sole crops and mixture are categorized as low to medium.

Abstract

Depth of sowing and shade levels were two ecological factors affecting early establishment of a plant. The effects of sowing depths of seeds and shade on seedling emergence, morphological traits and seedling biomass of Centrosema pubescens were examined. The seeds were sown at the depth of 2, 4, 6 and 8 cm and shaded at levels of 0 (full sunlight) and 50%. Analysis of variance showed a significant effect (P<0.05) of sowing depth on seedling performances. Sowing at the depth of 2 cm produced the highest percentage of seedling emergence, the shortest days to emergence, the biggest seedling diameter and thegreatest seedling biomass. Shade significantly (P<0.05) increased seedling height and shootroot dry weight ratio. The findings indicate that for improved growth and dry matter yield, Centrosema pubescens seeds should be sown at a depth of 2 cm.

Abstract

The aim of this research was to examine the feed rumen fermentation in the rumen of goat fed 4 different diets. This study was designed based on the Latin Square Design which consists of 4 diet treatments with 4 replications in each diet treatment. A total of 4 male goats, with relatively the same weight and age, were randomly assigned to an individual metabolic cage fed with 4 diets. The four diets studied were R1: Elephant grass, R2: Mini elephant grass, R3: Panicum maximum grass and R4: Brachiaria decumbens grass. Each diet was added with 20% of rice bran. The result of this experiment indicated that there was no any significant effect of different diets on the pH values, concentrations of VFA (Volatile fatty acids), and Ammonia (NH3) in the rumen of goat. The pH values in the rumen of goat treated with R1, R2, R3, and R4 were 7.17, 7.12, 7.07, and 7.0, respectively. The concentration of ammonia (mM) in the rumen of goat treated with R1, R2, R3, and R4 were 4.6, 3.3. 4.5, and 4.1, respectively. Whereas the level of VFA (mM) in the rumen of goat treated with R1, R2, R3, and R4 were 40.4, 43.6, 48.7, and 49.9, respectively. There was no any significantly difference (p>0.05) in the characteristic of rumen fermentation between the diet treatment. This might be due to the similarity in the nutrient content of those grasses studied. The characteristic of rumen fermentation was in the range of optimal growth of rumen microbes. It is concluded that those of four grasses studied edible, acceptable and contain a good nutrient as a feed resource for goat. The nutrient content of the grasses studied creates a good rumen environment for optimum feed fermentation in the rumen of goat.
