The study was conducted aiming to test different fertilizer doses on the optimal growth rate of Eucheuma cottonii seaweed. The study was conducted from July to August 2016 in the waters of Ghonebalano Village, Duruka District, Muna Regency, Southeast Sulawesi. The study used NPK fertilizer with the composition of the element nitrogen (N) 15%, phosphate (P2O5) 15%, and potassium (K2O) 15%. The study used a Randomized Block Design (RBD) with 3 (three) levels of fertilizer doses and 3 (three) groups so that the number of experimental units was 9 (nine) units. While the treatments tested in the study were treatment A (without fertilizer/control), treatment B (fertilizer dose 1 g/L), and treatment C (fertilizer dose 2 g/L). The results showed that the difference in fertilizer dose significantly affected the growth rate of Eucheuma cottonii seaweed. A dosage of 2 g/L of fertilizer gives the best rate of growth of Eucheuma cottonii seaweed while the water quality at the study site shows that it is still in the optimal range for the growth of Eucheuma cottonii seaweed.

Red chili (Capsicum annuum L.) is one of the vegetable commodities that has bright prospects and market demand continues to increase along with the increase in population, but until now the chili has not been able to meet the needs of the community. Efforts to increase production to meet needs that cover quality and quantity can be done by planting intercropping and fertilizing NPK Phonska. This study aims to determine the effect of NPK Phonska fertilizer on the growth and yield of intercropping of optimal chili and shallot plants. The experimental design used a Randomized Block Design (RBD) with a single factor pattern consisting of 5 NPK Phonska fertilizer treatments, namely BC0 = 0 kg ha-1 (control), BC1 = 300 kg ha-1, BC2 = 600 kg ha-1, BC3 = 900 kg ha-1, BC4 = 1200 kg ha-1. Non-destructive data collection is carried out. F test level 5% to test the effect of treatment, the difference between treatments was based on 5% BNT Value. The results showed that administration of NPK Phonska fertilizer had a very significant effect on chili plants, namely on growth variables and yields of plant height 26.14 cm, number of leaves of 15.11 strands, leaf area of ??11.86 cm2 and plant high onion 33, 34 cm, number of leaves 33.14 strands. The optimum dose of NPK Phonska fertilizer which provides optimal growth and yield of intercropping of chili and shallot plants is 1200 kg ha-1.

Abstract Beneficial effects of SCFA in modulating gut health stimulated interest on dietary strategies to increase intestinal microbial activity and digesta SCFA. Amylose has lower apparent ileal digestibility (AID) than amylopectin. In the large intestine, undigested starch is fermented by microbes producing SCFA. The objective was to determine effects of increasing dietary amylose on starch flow and metabolite profile along the intestinal tract in weaned pigs. Weaned pigs (n=32; initial BW, 8.4 kg) were randomly allocated to 4 diets containing 67% starch with 0, 20, 35, or 70% amylose in a randomized complete block design. On day 21, pigs were euthanized to collect digesta and feces for evaluating starch digestion and metabolite profiles. Apparent hindgut fermentation (AHF) was calculated as apparent total tract digestibility minus AID. Feed intake was 12% lower (P < 0.05) and growth rate was 18% lower (P < 0.05) for pigs fed 70% amylose than pigs fed 0, 20, or 35% amylose. Feed efficiency was greatest (P < 0.05) for pigs fed with 35% amylose. The AID of starch was 44% lower (P < 0.05) in pigs fed 70% amylose. Starch was completely digested by the proximal colon in pigs fed 0, 20, or 35% amylose, but AHF of starch was 14% greater (P < 0.05) in pigs fed 70% amylose. Increasing dietary amylose did not alter digesta SCFA in the small intestine, but increased (P < 0.05) digesta SCFA in the cecum, specifically acetate and total SCFA, and increased (P < 0.05) propionate and valerate in all sections of the colon. In conclusion, increasing dietary amylose in weaned pigs stimulated hindgut fermentation of starch with a corresponding increase in digesta total SCFA in the cecum and colon. Optimizing dietary amylose may exert its effect as dietary prebiotic while promoting an optimal growth rate in young pigs.

The present work aimed at determining the effects of the association between the periphyton-based system with the bioflocs-based system in the intensive culture of juvenile Nile tilapia (1.56 ± 0.07 g; 72 fish m-3), on variables of water quality, growth performance and effluent quality after 10 weeks. The experiment was arranged in a 2 x 2 factorial randomized block design with four treatments and five repetitions each. The factors tested were the following: ‘underwater structure’ (absence and presence) and ‘adjustment of the C: N ratio of water’ (no and yes). The final fish body weight, specific growth rate and yield were higher (p < 0.05) in the C: N-adjusted tanks. The presence of submerged structures in the tanks had no significant influence on those same variables. It was concluded that the periphyton-based system is not indicated for intensive farming of Nile tilapia, in which there is a high allowance of artificial feed to fish.

ABSTRACTPest and natural enemy population in three different rice cultivation in Sukamandi RegionSome on limiting factors in rice production include the cultivation system and pest damage. To suppress the damage, several control techniques have been applied, such as technical culture. The aim of this study was to gain information on population and pest damage, as well as natural enemy population in three different rice cultivation systems. The study was arranged in Randomized Block Design with three treatment and 9 replications. The treatments were: 1) organic rice cultivation, 2) semi organic, and 3) farmer technique. The used rice variety was Inpari 30. The plot size was 6 m x 90 m. The variables observed included population and pest damage, natural enemy population, and rice yields. Thirthy two rice hills were observed randomly in diagonal direction, with 2 weeks interval from two weeks after transplanting until harvest. The data were analyzed by analysis of variance (Anova) and the difference among the treatments was evaluated with Duncan multiple area test at 5% level. The results showed that brown plant hoppers population on organic rice cultivation is lower than semi-organic rice cultivation and farmer technique, but there were no difference of natural enemy population among treatments. The lowest yield was obtained from the organic rice cultivation (2.67 t/ha).Keywords: Rice cultivation, Pests, Natural enemiesABSTRAKBeberapa faktor pembatas produksi padi diantaranya adalah cara budidaya dan adanya serangan hama.
