Land is one of the potential natural resources to be developed optimally to increase local revenue. Based on the availability of water, land is grouped into two major groups, which are wetland and dry land (upland). The use of dry land for agriculture is often ignored by policy makers. Problems in dry land management vary in each region, both technical and socio-economic aspects. However, with the right strategy and technology, these problems can be overcome. Efforts to manage dry land to increase food production face problems, including steep slopes, low soil fertility, and water shortages. These problems need to be overcome by applying the right technology. Dry land management technology is available, including management of soil fertility, soil conservation, land rehabilitation, and efficient management of water resources. The problem is the weak dissemination of innovative technology to farmers and the slow adoption of this technology. Utilization of dry land to increase food production requires appropriate planning and strategies.
Penelitian ini bertujuan untuk mengetahui kinerja sistem zero water discharge melalui penambahan probiotik dan sumber karbon dari tepung tapioka pada tahap pendederan ikan bandeng (Chanos chanos) . Penelitian ini menggunakan dengan rancangan acak lengkap yang dengan tiga perlakuan dan tiga pengulangan. Perlakuan A : pendederan bandeng tanpa sistem ZWD, perlakuan B : pendederan bandeng sistem ZWD dengan penambahan probiotik, perlakuan C : pendederan bandeng ZWD dengan penambahan probiotik dan tepung tapioka. Hasil penelitian ini menunjukkan adanya perbedaan yang signifikan untuk setiap perlakuan (P<0,05) terhadap pertumbuhan dan kelangsungan nener ikan bandeng. Pertumbuhan dan kelangsungan hidup tertinggi dijumpai pada perlakuan C (zwd + probiotik + tepung tapioka) sebesar 0,11 g dan 75,56 %. Untuk parameter fisika-kimia air meliputi DO, suhu, pH salnitas, TAN dan nitrit masih berada pada kisaran yang baik untuk pendederan ikan bandeng.
purpose of this study is to determine the relationship between hatching egg weights with egg weight loss and DOC weights of Sentul male crosses with Nunukan broodstock. The tool used in this research is a unit of automatic digital hatching machine (temperature regulation and automatic turning). The research material was two male Sentul male chickens and four Nunukan mother chickens. The chicken is crossed and then the eggs are collected to be hatched eggs. The equipment used in this study is digital cameras, digital scales, calculators and stationery and table sheets for filling raw data. The coded eggs are put into the hatching machine for 21 days. The parameters measured in this study are; Hatching egg weight (Gram), egg weight Hatch day 18th, egg weight loss (%) / Egg shrinkage, DOC weight: DOC weight is measured by weighing the newly hatched chicks ie on days 21-22, the correlation value between weights hatching eggs with egg weight loss, the correlation value between hatching egg weight and DOC weighting. Data analysis using correlation. The results obtained are the average hatching egg weight of 45.13 ± 2.41 grams, the average hatching eggs on the 18th day 40.13 ± 2.18 grams, egg weight loss 11.08 ± 0.73%, DOC 34 weight, 04 ± 2.07 grams, correlation of hatching egg weight to DOC weight of 0.91, correlation of hatchingto egg weightegg weight loss -0.01. Based on the results of the study it can be concluded that the characteristics of Sentul crossbreed hatching eggs with Nunukan broodstock are in the normal range, correlation of hatching egg weight with very high DOC weight and positive correlation, correlation of hatchingwith egg weightegg weight loss lowand negative correlation.
This study aimed to test the level of dry matter and organic matter mulberry natural food and Gliricidia at Ettawa goat crossbreed (PE) males. This research was conducted in March and April 2016 in the village Ranomentaa Toari District of Kolaka. The material used is 12 PE male goats aged 4-6 months with a body weight of 10.44 ± 1.13 kg. Research compiled by complete randomized design (CRD) 3 treatments and 4 replications, P1 (100% mulberry), P2 (50% and 50% mulberry Gliricidia), P3 (100% Gliricidia). The parameters observed were dry matter intake (DMI), organic matter intake (OMI), dry matter digestibility (DMD) and organic matter digestibility (OMD). The data obtained were analyzed using ANOVA with F test (P <0.01 and P <0.05), when there is a continued effect with least significant difference test (BNT). Dry matter consumption and OMI highly significant (P <0.01), while DMD and OMD not significant (P> 0.05) as a result of treatment. DMI highest average at P3 (295.41 grams), in line with the highest OMI on P3 (271.21 grams). While the percentage DMD and OMD each ranging between 39.82 to 41.23% and from 40.55 to 43.87%. The absence of the effect of treatment on DMD and OMD caused by the degradation rate of the different natural feed caused by the content of crude fiber (CF) and lignin as well as anti-nutritive substances in the forage. Based on the results of the study concluded that the DMI and the best OMI on Gliricidia, but had no effect on DMD and OMD
