Comparative Study of Milk Production and Feed Efficiency Based on Farmers Best Practices and National Research Council
This study aimed to compare local dairy farmer ration formula with national research council in producing higher feed efficiency and milk production. This study had two stages. The first stage was in vitro study of dairy farmer rations which have different raw materials (R3, R4, and R5) with NRC based ration (R2) and Demo Farm ration (R1). The variables measured in this stage were proximate composition, volatile fatty acid, ammonia, dry matter and organic matter digestibility. The first stage used a randomized block design with five treatments, three groups of ruminal fluid, and three replications. The second stage used nine lactating cows with three periods of lactation (one, three, and other) and used a randomized block design with three treatments, three groups, and one replication. Parameters measured were dry matter intake, manure score, milk production, body weight gain, body condition score, and technical and economical efficiencies. The first stage result showed that R1, R2, and R3 were three best rations in nutrient composition and fermentability (ammonia and volatile fatty acid concentrations were optimum for microbial growth and high digestibility), so in conclusion those three rations were the best rations and should be compared by in vivo method. The result of the second stage showed that all tested rations were not significantly different in milk production, performance and efficiency, so in conclusion those three rations have the same quality
Fruit Characteristic and Nutrient Values of Four Indonesian Banana Cultivars (Musa Spp.) at Different Genomic Groups
Aims of this research were to describe the morphology and analyze nutrient values of mature fruits at three different genomic groups of Indonesian banana cultivars including Pisang Berlin (AA), Ambon Hijau (AAA), Raja Bandung (ABB) and Kepok (ABB). Fruit characterization results show that each banana cultivar had specific characteristics related to their genomic group. Pisang Berlin has bright yellow peel and pulp, sugary taste. Pisang Ambon Hijau has fine curved fruit shape, sweet taste and aromatic. Pisang Raja Bandung has medium thickness and yellow peel, firm flesh, sweet and slightly acidic taste. Pisang Kepok has thick coarse and yellow peel with dark brown blotches, mild sweet taste. Fruit characters of Pisang Berlin and Ambon Hijau are close related to their ancestral parents' Musa acuminata wild species, whereas Pisang Kepok and Pisang Raja Bandung as hybrid cultivars have intermediate characters between Musa acuminata and Musa balbisiana wild species. Nutrient analysis revealed that mature banana pulp contain of high carbo-hydrates (16.72-35.24 g 100g-1), total sugar (12.12-20.82 g 100g-1), vitamin C (16.45-30.27 g 100g-1) and potassium (275-375 g 100g-1); moderate protein (1.48-1.78 g 100g-1) and low fat (0.03-0.08 g 100g-1). About 100 g edible portion of banana fruit produce 73.43 to 148.80 calories
Pengaruh Pengadaan Bahan Pustaka terhadap Kepuasan Pemustaka di Kantor Arsip dan Perpustakaan Daerah Kabupaten Wonogiri
Penelitian ini berjudul “ Pengaruh pengadaan Bahan Pustaka terhadap Kepuasaan Pemustaka di Kantor Arsip dan Perpustakaan Daerah Kabupaten Wonogiri “. Adapun tujuan dari penelitian ini adalah untuk mengetahui dan menganalisa pengaruh pengadaan bahan pustaka terhadap kepuasaan pemustaka. Variabel dari penelitian ini adalah pengadaan bahan pustaka (X) dan kepuasan pemustaka (Y). Metode penelitian yang digunakan adalah metode kuantitatif. Jumlah populasi adalah 10.800 orang, sementara sampel dalam penelitian ini berjumlah 99 orang. Penarikan sampel dilakukan dengan purposive sampling. Metode pengumpulan data yang digunakan adalah observasi dan kuesioner. Teknik pengolahan dan analisis data menggunakan analisis deskriptif kuantitatif dengan menggunakan alat bantu pengolahan program SPSS versi 20. Kesimpulan dari penelitian ini adalah sebagian besar pemustaka memberikan tanggapan yang positif terhadap Pengadaan Bahan Pustaka dan kepuasan pemustaka. Hal ini ditunjukkan dengan prosentase pengadaan bahan pustaka berjumlah 48% dan 56% pada kepuasaan pemustaka. Uji Hipotesis menggunakan uji t. Hasil dari penelitian ini membuktikan bahwa hipotesis diterima karena ℎ= 7.024 > = 1.66071 sehingga dapat disimpulkan bahwa 0 ditolak dan 1 diterima artinya ada pengaruh yang signifikan antara pengadaan bahan pustaka terhadap kepuasan pemustaka
Pemanfaatan Air Cucian Surimi Belut Sawah (Monopterus Albus) Dalam Pembuatan Edible Film
The purpose of this research was to obtain edible film that meet physical and chemical characterictics of Japan Internasional Standard (JIS). This research was conducted from June 2015 to December 2015. This research used the randomized bloc design with one factor, the addition of eel surimi waste water (0 mL, 12 mL, 15 mL dan 18 mL). The observed parameters included chemical (water activity) and physical (thickness, percent of elongation, vapor transmission rate) characterictics. The results showed that there were no significant effects on thickness water activity, vapor transmission rate and percent of elongation. Furthermore, the edible film met Japan Industrial standard (JIS) based on thickness 0.139 to 0.214 mm, vapor transmission rate 3.514 to 7.133 g/m2/jam and the percent of elongation 106.22% to 174.55%
Distribusi Baru Dan Struktur Populasi Rafflesia Zollingeriana Koord. Di Taman Nasional Meru Betiri, Jawa Timur
Studi ini dilakukan pada bulan Juni–Juli 2012 untuk mengetahui sebaran terbaru Rafflesia zollingeriana dan struktur populasinya di Taman Nasional Meru Betiri. R. zollingeriana yang ditemukan sebanyak 19 populasi yang terdiri atas 26 koloni dan 152 individu. Populasi R. zollingeriana dominan ditemukan di lereng bukit, jauh dari pantai. Beberapa populasi berada di dekat pemukiman (kantong) dan di zona hutan dekat zona rehabilitasi. Dari 19 populasi yang telah diamati, sembilan merupakan distribusi baru yang belum pernah didokumentasikan dan satu di antaranya berada di luar kawasan TNMB. Populasi tersebut terdiri atas bunga mekar (7,89%), kuncup hidup (63,16%) dan kuncup mati (28,95%). Kuncup hidup dengan diameter 0,1–5 cm mendominasi populasi (50%), sedangkan kuncup yang siap mekar (diameter lebih dari 15 cm) hanya 0,42%. Tingkat keberhasilan kuncup untuk mekar diperkirakan rendah, sehingga keberlanjutan populasi R. zollingeriana terancam dan perlu dilestarikan, baik secara in situ maupun ex situ. Saran konservasi, baik secara in situ maupun ex situ disampaikan dalam makalah ini
Industrialization and De-industrialization in Indonesia 1983-2008: a Kaldorian Approach
Economists have for a long time discussed the causes of economic growth and the mechanisms behind it. Kaldor viewed advanced economies as having a dual nature verysimilar to that of developing countries, with an agricultural sector with low productivity and surplus labour, and a capital intensive industrial sector characterized by rapid technical change and increasing returns. The transfer of labour resources from the agricultural sector to the industrial sector depends on the growth of the latter's derived demand for labour. With this background this study attempts to show the periods when the Indonesian economy indicated the processes of industrialization and deindustrialization. Italso attempts to identify whether the economy experienced positive deindustrialization (i.e., showed signs of economic maturity where service sector substituted the role of industrial sector as the engine of growth) or negative deindustrialization (i.e., showed signs of economic stagnancy where industrial sector could not grow rapidly enough to absorb surplus labour from agricultural sector). Lastly, this study attemps to analyze several factors that might be responsible for the process of the deindustrialization
Dried Skeletonema Costatum in Feed Formulation for the Growth of Vaname Shrimp (Litopenaeus Vannamei)
The aim of this study was to determine the effect and the best dosage used by the Skeletonema costatum in feed formulation on the growth of Vaname shrimp. This experiment used Completely Randomized Design (CRD) with four treatments and three replications. Treatment was given by using dried S. costatum in feed formula (iso protein 37% and iso energy 3.6 kkal/g feed). Feed treatment was the substitution of fish meal protein A = 0%, B = 2.5%, C = 5% and D = 7.5% with dried S. costatum protein. The observed parameters include Survival Rate (SR), Survival Growth Rate (SGR), Feed Efficiency Ratio (FER), and Protein Efficiency Ratio (PER). The results showed that the use of dried S. costatum in feeding are effective in increasing the specific growth rate, feed efficiency ratio and the ratio of protein efficiency than controls. The best dosage in feeding formula is ranged from 4.39% to 4.75%
