Noodle is kind of most popular food. Dry noodle is raw noodle that dry till 8 - 10 % moisture contents. It’s raw material is wealth flour that imported. So that it is necessary to reduce wealth flour consumption in dry noodle production. It can substitute by yellow pumpkin. Yellow pumpkin is local plant that a lot. Angkak is fermented rice by Monascus sp that contain antosianin (red color agent) can use as natural colorant. So that, its need study to define exactly the percentage of wealth flour, yellow pumpkin and angkak flour in dry noodle production that accept by consumer. It is also to know the effect of yellow pumpkin and angkak addition on antioxidant activity and nutrient content (moisture, ash and protein content), also the effect on sensory character (color, aroma, elasticity, taste and overall). This study use factorial completely random design with two factors, first factor is the yellow pumpkin substitute (0%, 20 %, 30% and 40%) on wealth flour and second factor is the angkak flour addition (0%,1%,2%and 3%). The result of this study shown the most prefer yellow pumpkin percentage use by the panelist is dry noodle with 20 % substitute treat combine without angkak flour addition. As bigger as yellow pumpkin substitute will increase the moisture and ash content, then protein content and antioxidant activity insignificantly decrease. As bigger as angkak flour addition will increase the ash, protein content and antioxidant activity, then moisture content decrease. The dry noodle’s aroma and taste was unaffected by the yellow pumpkin substitute and angkak addition. As bigger as angkak flour addition, will decrease the elasticity score by the panelist. Overall parameter, was almost unaffected by the yellow pumpkin substitute and angkak addition. The highest score is dry noodle with 20 % yellow pumpkin substitute treat without angkak flour addition.

This study investigated the egg production pattern at the onset of lay until peak production in Japanese quails (Coturnix coturnix japonica) fed diet supplemented with betaine and methionine. Three hundred laying quails were randomly allocated to three groups of supplementations with 5 replicates of 20 quails. The three groups of treatments included basal diet (Control) or basal diet supplemented with 1.2 g betaine and 1.2 g methionine per kg diet. During onset of lay until 50% egg production (6 to 9 weeks of age), all groups were fed a basal diet, while the supplements were applied after 9 weeks. The egg production data were analyzed with analysis of variance and followed by Duncanâ€™s test for significant results. During week 6 to 9, all groups of quails generated similar egg production since they received the basal diet. On the later phase, supplementation of betaine and methionine enhanced average weekly egg production (P<0.05) starting from week 10 compared with those without supplementation. The egg production curves indicated that production rapidly reached 60% soon after the onset of lay. Then, egg production rose sharply and reached the peaks of more than 80%, indicating good egg production patterns. Supplementation of betaine and methionine enhanced the average overall and peak production (P<0.01) without affecting the age at peak production. In addition, there were positive correlations between average of overall production and peak production of all treatments. It can be concluded that supplementation of betaine and methionine enhanced egg production in quails.

The study site is administratively located at Ngadipiro village, Nguntoronadi subdistrict, Wonogiri regency with the total area of 663.61 ha. The coordinate of the study site lies at latitude of 7o52â€™00â€ â€“ 7o54â€™15â€ S and longtude of 110o57â€™45â€ â€“ 111o60â€™45â€ E and altitude of 196-427 m a.s.l. According to geomorphologic, the study site is a denudation hilly area, which severely scraped, with the type of primary land use is rainfed, which occupied by annual crops and seasonal crops. This reaserch were aimed at: 1) identify the physical problems and soil cultivation that have caused the land degradation; 2) obtain the alternative solutions for land degradation, which is suitable with the land physical condition. The type of this research is phenomenology description, with the method of surveying. Land mapping technique used the overlay of three maps, i.e: slope map, soil depth map and land use map, which is obtained from the interpretation of topographic map with the scale of 1:25.000. The obtained land unit was used for analysis unit. The land evaluation was carried out based on: 1) observations of land degradation indicators (land cover, outcrop, soil erosion, soil slide, bench erosion and soil depth); 2) soil erosion analysis with USLE formula, which described by soil hazard class. The alternative solution were based on the land degradation types, the threat levels of land degradation and the land management by farmers. Conclusions: physical problems found are: 1) the climate conditions promoted physical and chemical rocks weathering; 2) the volume of eroded soil corresponded to slope, which shaped â€œSâ€; soil management problem found are: 1) land management by farmers also could drive the land degradation, 2) the low level of farmers economical condition resisted the adoption of technology innovation by farmers. The alternative solution offered are minimum soil tillage (TOT) at 9, 10, 11 and 12 land units. On the other hand, the land units of 2, 3, 6, 7, 9, 10 and 12 required the roraks construction and the planting of cover crops and annual crops periodically.
