Abstract

Land degradation on the upper stream area in Ambon island has reduced the availability of fresh water for the peoples. An available fresh water supports only 19.14% of total population.  This research was carried out to solve the problem of water resources shortage in Ambon city which is sourced from Batugantung.  The objectives of this research were to evaluate the impact of land use changes on the income, hydrological characteristics, erosion and sedimentation in Batugantung watershed. The result of this research showed that the increasing density and coverage of vegetation can increase the sustainability of land and water resources.  The increasing vegetation density in agroforestry land use can imitate the role of forest in sustaining watershed hydrological function, decreasing runoff, controlling erosion as well as  increasing farmer’s  income.  By keeping  at least 30% forest in dusun land use management in  Batugantung watershed, it can sustain water yield about 75.66 liters.s-1, decrease erosion to 27.62 ton.year-1, and increase farmers income up to Rp. 15.64 million ha-1.year-1.   By applying  the result of this research to other watersheds in Ambon island, the availability water resources will be about 13.07 x 105 m3.day-1. This amount of water resources can fulfill present total requirement of fresh water for  380 thousand peoples in Ambon island which is only  6.08 x 104  m3.day-1.

Abstract

Gandaria (Bouea macrophylla Griff) is well-known as one of native typical fruits in Mollucas which needs to be preserved and continuously cultivated because of economical and ecological significances. Hunuth is well-known as a production centre of gandaria in Ambon. The research aimed to identify the characteristics land of gandaria. The research was done from March to May 2012 using survey and interview method. The result showed that gandaria in the research location was well adapted. Altitude is from 1 to 36 above sea level (a.s.l). Topography is from slightly tilted/wavy to slightly step. Based on climate classification by Schmidth and Fergusson, climate type of research location was in B (wet) region with the amount of annual rainfall 3030.10 mm on average. Temperature at average 14.87 to 22.29 oC , humidity on average 55.30 to 68.18 % and sun photoperiod on average  18.52 to 50.17 percent. The dominant soil type in research location were Alluvial and Cambisol.

Abstract

One of the constraints faced by farmers in the cultivation of chili in Transmigration Areas District Kairatu Waimital Village is a disease caused by virus. This study was conducted to know the types of viruses that attack chili plants and how worse the damage intensity. The method used was a survey method directly in the field. Farmer decision-sample and sample plots was done using a random sampling technique. The data collected is the damage intensity of chili plants and the cause, the condition of the area/crop cultivation techniques, and rainfall data taken from Meteorology station (BMG). The results showed that the disease that attacks the chili plants in the Waimital village is a yellow virus and curl virus disease, with intensity of damage of 10.16% and 32.17% classified as mild and moderate, respectively.

Abstract

Fruit flies (Diptera: Tephritidae) are important pests of horticultural crops with the intensity of their attacks can achieve 100%.  The control by quarantine regulations and the use of attractants will be more successful when the information about the species that attack horticultural crops has been known clearly. This study aimed to identify the species of fruit fly that attack pepper (Capsicum annum), bitter melon, guava and guava bol and to know the number and sex ratio of fruit fly pests. The method used was the survey methods, by taking/collecting pepper, bitter melon, guava and guava bol which contained fruit fly attack symptoms, maintained until it was discovered in the imago, later it was identified. Based on the results of the study, we found that fruit flies that attack the chili was B. papaya, in bitter melon was B. cucurbitae, in bool guava fruit and guava was B. Albistrigata. The number of fruit flies in chili was 21, in bitter melon was176, 89 in bol guava, and in guava was 90. Sex ratio in chili fruit flies (1:1), bitter melon (1:1), guava bol (1:1) and guava (2:1).

Abstract

Nitrogen is a major nutrient for plant growth, nitrogen was absorbed by plant roots in the form of NO3-(nitrate) and NH4+ (ammonium). Nitrogen deficiency affects negatively on plants, like stunted plant, leaf turns yellow, and limited rooting system, while excess nitrogen causes elongated vegetative growth, easy to fall down, reduce the grain quality and its response to pests and diseases. The purpose of this study is to determine the available soil-N, plant N uptake and growth as well as the yield of paddy rice (Oryza sativa L) due to the treatment of straw compost and NPK fertilizer. Treatment was carried out in a factorial experiment designed in randomized block design, the straw compost factor consisted of  two dose levels: 0 and 3.0 ton ha-1 and NPK fertilizer factor consisted of five dose levels: 0, 75, 150, 225, and 300 kg ha-1 with three replications. Research findings indicated that the amendment of straw compost together with NPK fertilizer increased the plant uptake of N, but straw compost improved independently the soil-N, and plant growth (plant height and number of tillers/clump). Likewise, NPK fertilizer independently increased soil-N, growth parameter (plant height and number of tillers/clump) and grain yield (number of grains/panicle and number of filled grain/panicle). The straw compost amendment at 3 tons ha-1 along with 150 kg NPK ha-1 resulted the highest N-uptake of 3.51%.

Abstract

The experiment was conducted to determine and map the land suitability of  lychee plant in Naku village. The results showed land units that belong to the class of land suitability (S1)  were GD1 and GD2 covering  4.6 ha (2.42%). Land units that included the class of  marginally suitable land (S3) was GD4 covering 1.9 ha (1.0%). The limiting factor was the slope of 15-30% and  depth of solum 50-75 cm. Not suitable land (N) were the land units GD3, GD5, GD6, GK1, GK2, GK3, GK4 and A1 covering 184.1 ha (96.58%)   Limiting factor on the land unit GD3 was depth of solum <50 cm, on GD5 was 30-45% slope, and solum depth of 50 cm, on GD6 was a slope > 45%, on GK1 - GK4 was coarse/very coarse texture, on GK5 was the slope of 30-45 % as well as coarse texture, on GK6 was slope > 45% and very coarse texture, and the limiting factor for the A1 unit was a very coarse texture. The potential land capacity for Lychee plants in  Naku Village was area of 6.5 ha or 3.41% of the land area in the Naku village.
