Proline is one of amino acid that usually accumulates inside the plant cell when facing drought stress. The accumulation of proline can protect the plant cell from damage during drought. The aim of this research was to determine proline content and yield components of local corn cultivars from Kisar Island, Maluku, Indonesia. The field trial was organized using randomized block design with three replicates. Six local corn cultivars found in Kisar Island (Deep Yellow, Early Maturing Yellow, Red Blood, Rubby Brown Cob, Waxy, and White) were used as plant materials and a recommended tolerance variety (<em>Srikandi</em>) was taken as reference group. Proline content was determined using ninhydrin method. Yield components variables included cob weight (at harvest, after air dry, after oven dried, at 12% of water content), cob water content at harvest, cob length, cob diameter, number of seed row per cob, number of seed per cob, and cob yield at 12% of water content. Data collected was analysed with analysis of variance followed by Duncan multiple range test at the significant level 0.05 using Statistical Analysis System/SAS software version 9.0. The result shows that highest proline content and yield components (except for cob water content) was showed by the Deep Yellow cultivar. The lowest proline content was showed by Rubby Brown Cob cultivar. The lowest corn yield components was showed by Red Blood local cultivar. Deep Yellow cultivar can be proposed as superior drought tolerance variety, and can be recommended for further wide cultivation in Maluku province.

Background: The aim of this research was want to know the effect of GA concentration with soaking time towards seedling germination of soursop, and to know whichone of the treatment that can give a very highest quality and quantity of seedling germination of soursop. Method: This research started from  Juny until  July 2011. Factorial pattern of completely randomized block design (RAL) were used in this research, which consist of two factors. First factor where concentration of GA with four level i.e. A1= 5 PPM, A2 = 10 PPM, A3 = 15 PPM, and A4 = 20 PPM. While the second factor where soaking time which consist of three level i.e. L1= soaking for six hour, L2 = soaking for twelve hours, L3 = soaking for twenty-four hours. Each combination with three replicated. Data collected were analyzed used analysis of variance at the significant level of α 0,05 and 0,01. Result: Percentage obtained at the A3L2 treatment i.e. 100 %, plant high 16,12 cm, and root length 12,99 cm. It can be concluding that GA and soaking time treatment, can affected the seedling germination of soursop. Conclusion: Based on the results obtained it can be concluded that the use of GA concentration and different soaking time on seed soursop significant effect on percentage germination, high germination and seedling root length.

As a staple food, which consumed by many peoples in almost all places world wide, corn (Zea mays L.) has become very important. As well as in Indonesia, especially in Kisar Island, Southwest Maluku regency, corn already be the one of the most important food crops. The purpose of this study was to determine proximate content of local corn kernels from Kisar Island Maluku. Proximate analysis included content of water, fat, protein, ash, crude fiber, total carbohydrate and total sugar. Data collected are presented in form of table and analyzed descriptively. The data obtained were compared to the Indonesian national standard (SNI) of proximate content for corn kernels as well as to other results that have been reported by several researchers. The results of seven local corn cultivars from Kisar Island were in accordance with SNI standards about content of ash (1.13-2.04%), protein (9.14-13.02%), crude fiber (2.17 - 2.72%), fat (3.47-5.10% ), total carbohydrate (69.7 % -75.74%), and total sugar (58.66% -68.7%). The novelty of this research is to reveal the proximate content of local corn kernels from Kisar Island. This research is expected to be useful as a source of information about the proximate content of local corn seeds, and for instance it can be considered in the utilization and development of local corn in Kisar Island.

Background: Pakcoy (Brassica chinensis L.) is a vegetable plant originating from China that has leaf stalks that are wider and larger than green mustard greens. Pakcoy has nutritional value such as vitamin C, vitamin A, carbohydrates, fiber, protein, calcium, magnesium. Chlorophyll is a green leaf substance found in green parts of plants, especially on leaves. One of the factors that influence the chlorophyll content in pakcoy mustard leaves is the soil condition in this case the nutrient content and nutrients in the soil. One way to meet nutrient and nutrient content in the soil is by using organic fertilizers such as manure and tofu. Method: This study aims to determine the chlorophyll content of pakcoy leaves (Brassica chinensis L.) after giving manure and tofu dregs. Based on the analysis of chlorophyll content using the UV-VIS spectrophotometer method at wavelengths of 644 nm and 663 nm. Results: The highest levels of chlorophyll A in pakcoy (Brassica chinensis L.) leaves with PK3AT1 treatment (7 kg manure and 7 kg tofu dregs) of 2.007 mg / L, highest chlorophyll B levels in pakcoy (Brassica chinensis L.) leaves with treatment PK3AT3 (7 kg manure and tofu dregs 3 kg) at 2.674 mg / L, and the highest total chlorophyll content in pakcoy (Brassica chinensis L.) leaves with PK3AT1 treatment (7 kg manure and 7 kg tofu dregs) at 4,558 mg / L. Conclusion: Chlorophyll A, B and total levels in pakchoy (Brassica chinensis L.) leaves after a combination of manure and tofu dregs have high levels of different corophils.
