Keragaan Produksi Ayam Broiler Pada Berbagai Metode Pemberian Pakan dan Tipe Lantai Kandang
Get PDFThe aim of this study was to determine the effect of the restriction of feed and the type of cage floor as well as its interaction to production performance in broiler chickens. This study will use 100 DOC (Day Old Chick) day old which consists of 90 major research and an additional 10 to see the state over crowded. The treatments consisted of two factors: The first factor restrictions on feeding consists of: (1) Without limiting the feed (ad libitum), (2) Restrictions feed 15%, and (3) skip a day (feeding hoses one day). The second factor is the type of cage floor consists of: (1) Floor-type wire cages (cage), and (2) Floor type cage litter. The result of this research showed that ad libitum, restricted feeding 15% and skip a day feeding were significantly (P £ 0.01) influence to final body weight, body weight gain, feed consumption kumulatif, and feed conversion. While type cages and interaction were no significantly (P ³ 0.05) on all variable production of broiler chicken
Pemberian Pakan Basah pada Ayam Buras untuk Menurunkan Rasio Konversi Pakan (FCR)
Get PDFNative chicken is one of the livestock that is widely maintained in rural areas in Bali, to fulfil meat and eggs as a food consumption and also for religious ceremonies. However, the population of native chicken continues to decline until 4.15% in average every year due to high price of feed and nature behaviour of the chicken that picks food either by mouth or legs causes a lot of food to be wasted. To minimize the amount of wasted food, given the wet form of feed given in accordance with the needs for production. The study was carried out in Tembuku Subdistrict, Bangli Regency, using 90 laying hens which were divided into 3 group of treatments each with 30 chickens and differentiated between wet feed and dry (ordinary) feed. Where P0 is control, P1 is given Bio L Probiotics 3 cc.liter-1 of drinking water and P2: P1 + Herbs 4 cc.liter-1 of drinking water. The results showed that P0B: 56.71% P0K: 57.54%; P1B: 58.9; P1K 59.73% and P2B: 61.08; P2K: 60.15. The highest productivity were found at P2B and P2K. While the FCR achieved by each treatment were P0B: 3.35; P0K; 3.56; P1B: 3.07; P1K: 3.24 and P2B: 2.98; P2K: 3.13. These results indicate that the providing of wet feed produces a lower FCR than dry feed. The providing of Bio L probiotics could increase productivit
Pengujian Daya Hasil Beberapa Varietas Tanaman Jagung pada Kondisi Cekaman Kekeringan yang Diberi Pupuk Kandang di Lahan Kering Lombok Utara
Get PDFThis study aimed to determine the efficacy of several varieties of maize at various rate of manure under drought condition on the dry land of North Lombok. The experiments were designed using split plot design, with manure rates (0, 5, 10, 15 and 20 t.ha-1) as the main plots, and five different maize varieties (P4IS, Gumarang, Lamuru, Sukmaraga and NK212 Hybrid) as subplots. The efficacy of several maize varieties were determined from the weight of dry seeds per plant. Experimental data were analyzed using analysis of variance (ANOVA) at 5 percent significant levels. The mean of each treatments was further tested using the Honestly Significant Difference (HSD) at the same level. The results showed that the highest yield of maize crop was obtained on Lamuru variety at rate of manure of 20 t/ha, ie 85.94 g.plant-1 or 6.14 t.ha-1. The yield of Lamuru variety is similar to that of Sukmaraga, but it is higher compared to P4IS, Gumarang and Hybrid of NK212.The highest yield of maize crop was obtained at rate of manureof 20t.ha-1

Get PDFThe experimental research is aimed to find out the kind of nursery organic media for better growth of drumstick seedling. It was implemented in January-April 2017 in the nursery field in Dasan Agung, Mataram. The treatments studied were kinds of nursery media including soil media, mixture of soil-sawdust, mixture of soil-cocopeat, mixture of soil-crushed corncobs, mixture of soil-bamboo leaf litter. The experiment design was arranged in a Completely Randomized Design with 5 replications and each content of 5 serial experiment units. The result shows that the kind of seedling media significantly affected the growth to Moringa seedling growth. The soil-cocopeat mixture medium, soil-crushed corn cobs, and soil-bamboo leaf litter were the best medium and more suitable for drumstick seedling compared to soil media and soil-sawdust mixture medi
Biosorben Kulit Jengkol sebagai Penyerap Logam Pb pada Air Kolong Pasca Penambangan Timah
No full textPost-tin mining has caused a major problem in the Province of Bangka Belitung Islands, which leaves declining water quality of dam-water. The aim of this study is to employing jengkol shells to adsorb Pb metal from post tin-mining water. Biosorbent preparation from jengkol (Pithecellobium jiringa) shells was done by HNO3 activation. Metal absorption by biosorbent was applied to post tin-mining water. The functional groups involved in the adsorption process are studied by FTIR characterization. The results showed a shift of wave numbers in hydroxyl, sulfonyl and phosphate groups proving that these three functional groups were involved in absorb of Pb metal on the surface of biosorben

Get PDFThis study aims to determine the response of corn-sorghum cropping patterns on several environmentally friendly fertilization packages that can improve the quality of soil fertility streamline the use of inorganic fertilizers and improve crop yields on dry land. This research was conducted at Akar-Akar Village, Bayan District, North Lombok. The experimental design used was a Randomized Block Design, by testing five environmentally friendly fertilization packages on the corn-sorghum cropping pattern and repeated 4 times. The results showed that the response of maize-sorghum cropping patterns to the fertilizing package 60% lower than the recommended fertilizer dosage with the addition of 12 tons of manure per ha accompanied by mycorrhizal inoculation increasing soil fertility shown by increasing nutrient status of N, P, K and ingredients soil organic matter, increasing plant nutrient uptake (N, P, K and Ca), growth, crop yields and MA activity in the soil.Â
Rancang Bangun Alat Ukur Monitoring Dan Pengukuran Kontaminasi Tanah (Studi Kasus: Desa Pelangan Kecamatan Sekotong)
Get PDFGold processing waste contains many chemicals compound such as mercury and cyanide, which may help change the physical character of soil. In this study, the temperature, humidity and soil pH has been measured. Measurements of temperature and soil moisture are carried out using SHT11 sensors directly during gold processing. Measurements were carried out around the pond in three different directions. Each direction has 6 points, spaced 5 m apart. Measurements at one point are carried out for 20-21 hours. The measurement results are then mapped to a contour using Surfer-13. Based on the measurement results, obtained temperature values for all points are in the range 25.2-30.3 °C. While the value of soil moisture around 63.8-89.9%, and the soil pH value ranged from 6.8 to 8.1. The mapping results shows the distribution of temperature, humidity and soil pH with almost the same pattern, where the mercury concentration is linear with soil temperature, and soil pH, but non-linear with soil moistur
Persepsi Peternak Terhadap Aspek Reproduksi Ternak Kambing di Kabupaten Lombok Utara
Get PDFThe research conducted in order to know farmer perception on goat reproduction in North Lombok District. Farmer groupswereselected by purposive random sampling. Each group represented by 10 respondents. Collected data then tabulated and quantified, interpreted and presented descriptively. The initial populations in the past 5.6 years were 243 (50 males and 193 females), currently remaining458 (340 females and 118 males) excluding those weresold. 80% of respondents know the age of doe’s at the first mating and 88.8% know oestrus signs. 67% of respondents did not know post kidding open days. 100% doe's were naturally mated. 50% respondents stated mating frequenciesfor optimum fertility rate was 1-2 times, 12% said 3-4 times and the remaining 38% did not know. Only 56.7% of respondents knew doe’slength ofpregnancy. Doe’s with twins of two or morekidding were 59.3% and single kid was 40.70%. Almost 100% of respondents know genetically superior bucks. In conclusion, on one hand the perception of respondent's on goat reproduction is relatively low, but on the other hand the goat production was relatively high. To accelerate the increase in productivity of goats in North Lombok Regency, was recommended that local goats are crossed with superior goats such as Ettawa goats or Boer goat
