The aim of this study was to measure the resistance of several sweet potato genotypes to C. formicarus Fabricus (Coleoptera: Curculionidae) attack. The design used in this study was a randomized block design (RAK) with 9 treatments and 3 replications, so that 27 experimental units were obtained. The genotype treatmens were Antin 1, Antin 2, Antin 3, Koya 2, Koya 4, Koya 6, Beta 2, Kidal, and Salosa. The results of the analysis showed that all of the tested genotypes were naturally damaged by C. formicarius pests both at the base of the stem and on the tubers. The intensity of tuber damage caused by C. formicarius among 9 tested genotypes was the highest in the Salosa genotype (17.593%) and the lowest was in the Antin 1 genotype (5.553%). The intensity of damage to the base of the stem caused by C. formicarius among the 9 genotypes tested was the highest in the Antin 1 genotype (61.110%) and the lowest was in the Left-handed genotype (47,333%). Colonization (infestation) of C. formicarius in the test genotype occurred from the beginning of the observation at 4 week until the plants were harvested (tubers formed). The egg and larvae populations in this study were not found, while the number of imago from each test genotype was different with the highest population was in the Antin 1 genotype (3,3200 individuals), then the lowest imago population was in the Antin 3 and salosa genotypes with an average value of 2.1467 individuals. The resistant genotypes were Koya 4, Salosa, and Beta 2, while genotypes that were moderately resistant were Koya 2, Kidal, Antin 3, but Antin 2, Koya 6 and Antin 1 were sensitive genotypes.

The purpose of this study was to identify the area distribution of Sustainable Food Agricultural Land (LP2B) in Bowi Subur Village (SP6) Masni District. The methods used are spatial methods and field surveys. Observational variables in this study include data on paddy fields based on lowland rice cultivation techniques, lowland rice productivity results, irrigation facilities and farmer responses regarding lowland rice cultivation. The results of this study found that Bowi Subur Village in recent years experienced a decrease in productivity, which was only 0.69 to 1.1 tons/ha due to the acidic nature of the soil, and damaged irrigation networks that were still being renovated, so to meet the needs of life, farmers sold land. rice fields, and finally change the function of the land. There were 3 categories of land availability for LP2B in Bowi Subur Village, namely very eligible, eligible and inappropriate. Very eligible criteria for LP2B has an area of 14 ha, while Eligible criteria and unfeasible criteria for LP2B have area of 23.5 ha and 11 ha, respectively.

This research aimed to study the effect of garlic extract on the growth of stem cuttings of several types of bougainvillea and used a factorial randomized block design (RAK) with two factors. First factor is garlic extract in 2 levels, (with or without garlic extract). Second factor 2 is the type of bougainvillea consisting of 5 varieties such as yellow flowers, dark purple flowers, white flowers, red flowers and orange flowers. The results showed that the interaction between onion extract and bougainvillea had no significant effect on all observed variables (sprouting time, number of shoots, shoot length, number of roots, root length, percentage of cuttings sprouted and percentage of rooted cuttings). Garlic extract had no significant effect on all observed variables. There was a tendency for cuttings given garlic extract to show a faster age of budding, more shoots, longer roots and more roots. The type of bougainvillea gave a very significant effect on all observed variables except the number of shoots. Red flowers show the earliest age to start sprouting (16.80 days), the longest shoots (26.03 cm) and the longest roots (9.43 cm). Orange flowers performed the highest number of shoots (4.79), the highest percentage of shoots (96.67%) and the highest percentage of roots (96.67). Yellow flowers showed the latest sprouting time (37.08 days), the shortest shoot length (2.51 cm), the shortest root length (1.56 cm), and the least number of roots (1.06). Dark purple flowers showed the lowest percentage of budding and root percentage (63.33%).

This objective of the study is to determine the effect of potassium nutrition on stomatal aperture and drought resistance. Research has been conducted in the greenhouse of the Faculty of Agriculture, Gadjah Mada University in March-May 2012. This experiment was arranged on Factorial Completely Randomized Design (RAKL). The first factor was KCl consist of three level thoose are 0 kg ha-1, 50 kg ha-1, and 100 kg ha-1. The second factor was water consist of four levels which wereenough water and less water. Parameters observed were periodic observations on plant height while the observations made at the first harvest and the end covers root dry weight, shoot dry weight, total dry weight, leaf area, stomatal aperture and proline compound content. The results showed that potassium fertilization affect proline levels in maize, proline accumulation also significantly affected by water deficit conditions. The relationship between stomatal aperture width is closely related to water stress conditions that can increase the accumulation of proline.
