Abstract

The study aims at determining, firstly, the effect of chicken manure dose on the growth and crop result of sweet potato (Ipoma batatas), Cilembu Variety, secondly, determining the optimum dose of chicken manure which can lead the best of growth and yield of sweet potato (Cilembu variety). The method used at this research is completely randomized design, and the treatments are K0 (non-fertilizer), K1 (dose of 10 tons/ha), K2 (dose of 20 tons/ha), K3 (dose of 30 tons/ha). Observation variables in this study are the length of the rod, number of leaves, leaf area, number of wet bulb per plant, berangkasan weight, wet weight of bulb per plant, length of the bulb, the diameter of the bulb, and weight of wet bulb per hectare. The result of this research indicates that the giving of chicken manure, giving a good influence at the growth and yield of Cilembu sweet potato and real affect long stem at the age of 2, 6, and 8 mst of age, and wide leaf index at age 2, 4, and 6 mst. Production components have significantly affected for berangkasan weight, wet weight of bulb per plant, length of the bulb, the diameter of bulb and weight of wet bulb per hectare. The optimum dose of chicken manure was obtained with a dose of 20 tons per hectare which can raise the growth of stem length of Cilembu Sweet Potato (80,85 cm) and the crop of Cilembu sweet potato (731, 72 kg/ha).

Abstract

The goal of this research was to understand the diversity of soil mesofauna native to different plant habitats in the area of Kelimutu National Park and to understand how the dominant soil mesofaunal populations vary depending on vegetative diversity. This research was conducted in a number of different vegetation habitat zones according to the intensity of land use in the area of Kelimutu National Park and in the laboratories at the University of Flores in the city of Ende. This research was designed in a linear method and sampled vegetation from areas labelled VR (Vacciniumvaringiaefoliumdan Rhododendron renschiamum), VCa (mixed forest) and VC (coniferous forest). The results of this research show that the area near Kelimutu National Park contains low to medium diversity. Low diversity was observed in areas with vegetation VR with5 types of soil mesofauna (H’:1.153) whereas medium diversity was observed in areas with vegetation VCa, with researchers finding 7 types of soil mesofauna (H’:1.771). Six types of soil mesofauna were found in areas with vegetation type VC (H’:1.727). Vegetative diversity was found to be linked to the increasing dominance of soil mesofauna in the area of Kelimutu National Park. The highest value of vegetative diversity was (H’:1.821), found in area VCa with the dominance of soil mesofauna (E:0,85). For area VR, the vegetative diversity was (H’:1,771) with a dominant soil mesofauna value of (E:0.72) and for vegetation VC the vegetative diversity was (H’:0.861) with dominant soil mesofauna value of (E: 0,28).

Abstract

Salt is a dietary mineral composed primarily of sodium chloride. These two components of salt are an essential nutrient for humans with important functions in regulating the extracellular fluid volume and the active transport of molecules across cell membranes. However, having too much salt in the diet increases the risk of health problems. High sodium intake is positively correlated with the level of blood pressure. Therefore, it is necessary to consume food with reduced salt content. Salt has been used as a food preservative that kills or limits of foodborne pathogens and spoilage organism by decreasing water activity. Salt also has functions in foods by adding flavour and masking bitter tastes, controlling the growth of yeast and strengthening the dough network and gas retention of the dough. Reducing salt content in processed food especially for bread-based products is one of the greatest ongoing challenges facing food manufactures. It also has been difficult to reduce or remove salt or sodium chloride from bread since salt is one of the four essential ingredients in bread. Reducing salt level from 1.2% does not significantly affect dough rheological properties and bread-making quality. However, the omission of salt entirely leads to a significant reduction in the dough, bread quality and its palatability.

Abstract

Tropical rainforest deforestation is a major problem in many tropical regions and can have major impacts on system ecology and long term soil productivity. This paper examines the trend of increased colonization of tropical rainforest regions and the resulting effects on long term natural system productivity in these areas. It also explores the impact of conventional agricultural practices, the majority of which were developed in temperate climates, when employed in a tropical context. International trends in the consumption of imported tropical wood and rainforest products are also suggested as a major culprit for increased tropical deforestation. Reduction in international rainforest product consumption and greater awareness on the part of Western consumers as to the impacts of tropical deforestation are suggested as potential solutions to reduce this problem.

Abstract

The aim of this study was to understand the benefits of ‘kirinyu’ as a resource of organic matter in the growth and production of carrots and determine the optimum quantities required. The study used a random group design method using K0 (without kirinyu), K1 (kirinyu 5 ton/ha), K2 (kirinyu10 ton/ha), K3 K3 (Kirinyu 15 ton/ha), and K4 (Kirinyu 20 ton/ha). The variables measured in this study were; plant height, the total number of leaves, length of tubers, the diameter of tubers and weight of fresh tubers per plant per plot and per ha. The results of this study indicate that the use of ‘kirinyu’ as a source of organic matter has a definite influence in the plant height in the ages of 4 MST, 8 MST, 10 MST, 12 MST, and total leaves in the ages of 6 MST, 8 MST. Also, it influences the length of tubers, the weight of tubers per plant per plot and per ha. It was determined that optimum growth of carrots; that is plant height (32.51 cm) total leaves (5.78 cm) length of tubers (10.71 cm) was attained with the use of 20 ton/ha weight of fresh tubers per plant (48.19 grams), per plot (7,93 kg) and per ha (21089,29 kg).

Abstract

This research was carried out in order to understand the main types of pests and diseases that affect corn, which types are most dominant and to understand the severity of these main diseases in corn. Observation of variables involved the identification of pests and diseases that attacked corn plants, the diversity of these pests and diseases as well as the intensity of the damage caused by these pests and diseases. The results of this research showed that the main type of pest and disease that attacks corn are, among others: seedling flies (Atherigonasp), grasshoppers (Oxyasp), corn stalk drillers (Ostrineafurnacalis) and leaf rust. The most dominant type of pest or disease were grasshoppers (Oxyasp) which attacked plant leaves. The seriousness of an attack by a pest or disease was found to be important in the seedling phase, there are many variations in between species of corn and also developed with the age of the corn. At 12 days after planting, the incidence of insect attack was0.2% and at 33 days and 54 days after planting it was 0.32-0.47%. Whereas for disease, when observed at 33 and 54 days after planting, the average incidence of disease attack was 0.05-0.23%. Also, when observed at 61 days and 75 days, the incidence of attack rose to 0.32-40%.

Abstract

The goal of this research was to understand the biology of P. marginatus, a common pest for papaya plants. This research used 1 type of treatment which was repeated 10 times. The results of this research were intended to illustrate the average development time of each development phase of P. marginatus. These phases were: the egg phase (6 days), the female nymph phase (10 days), the male nymph phase (17 days), female adult stage (11 days), male adult stage (3 days). On average, the female life cycle was 27 days, and the male life cycle was 26 days. On average, the pre-fertile stage lasted 4 days, the fertile stage lasted 6 days and the post fertile stage lasted 1 day. On average the pre-egg-laying adult stage lasted 4 days, the egg-laying adult stage lasted 6 days and the post-egg-laying stage lasted 1 day. After the egg-laying stage, the average fecundity of P. marginatus was 370 eggs per female and from these, a total of 350 offspring were hatched per individual. The ratio of surviving Descendents to reproductive couples of P. marginatus white lice was 9:1.
