Abstract

Land use is the element that changes very dynamic area. This is due to various human activities depend on the elements of this land. One of the most influential factor in the speed of change in land use or land use change is the increase of population in an area. Fulfillment of human needs (food, clothing and shelter) is influenced by the availability of land. This study aims to identify and analyze the rate of land conversion in conjunction with the growth of population in the peninsula Leitimur Ambon Island. The method used is descriptive with population growth comparing data (statistics) with patterns of changes in land use map data obtained from Ambon city land use remote sensing and data. The rate of population growth in the city of Ambon Leitimur Peninsula in the last 10 years (2000-2010) shows the percentage figures are quite high, 179,78 percent and with a population density of 1.145,436 inhabitants/km2. Land conversion that occurred in the Peninsula Leitimur of the Year 1984 - 2010 are as follows: (1) forest becomes 3.008,06 to  1.057,69 ha; (2) be mixed farms 5.533,46 to 8.671,97 ha; (3) vacant land 0,00 ha to 94.67 ha; (4) settlements be 2.768,58  to 3.129,83 ha; (5) bushes and reeds 4.113,39  to 1.372,58 ha;  and (6) other use 0.00 ha to 1.150,75 ha. From these results show that the rate of change (conversion) of land is directly proportional to the growth of population.

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

Antrachnose disease caused by Colletotrichum sp. is one of the important diseases of strawberry in the field or after postharvest. The environmentally-friendly control measures is the use of botanical pesticides. Botanical pesticides that are commonly used by the farmers are mixture of several kinds of plant extract. This paper discuses the effects of combining water extract of garlic, galangal rhizome, and betel leaves on their efficacy in inhibiting conidial germination of Colletotrichum sp., the growth of miselium in vitro and the development of antracnose disease in strawberry. Preliminary study was conducted to determine the concentration of the extract that was used for further experiment. The experiment was arranged in the completely randomized design with 10 treatments involving water extract of garlic, galangal rhizome, betel leaves and their mixtures, fungicide and control/check. Each treatment was repeated three times.The results showed that combination of water extract of garlic, galangal rhizome and betel leaves did not enhance their efficacy. The inhibition effect of garlic water extract (5% concentration) was relatively better than its mixtures with galangal and betel leaves (total concentration 15%). The effects of galangal rhizome or betel leaves water extract and their mixtures were not significantly different. Water extract of garlic (15 %) inhibited Colletotrichum sp. which was showed by inhibition zone of 9.3 mm width; and suppressed the antrachnose disease in strawberry stolon by 83,7 %.

Abstract

Dendrobium anosmum is one of natural orchids in Indonesia. Optimization of medium composition for orchid propagation through in vitro culture is necessary to enhance propagule multiplication capabilities and quality. This study was aimed to study the influence of concentration of coconut water in culture medium on in vitro growth and development of D. anosmum orchid species and to determine the optimal coconut water concentration in culture media.  The experiment were arranged in a Completely Randomized Design with four treatments and eight replications. The treatments consisted of the addition of coconut water with concentrations: 0 ml•l -1 (control), 50 ml•l-1, 100 ml•l-1 and 150 ml•l-1. The results showed that addition of coconut water in culture medium gave different effect on shoot growth and multiplication of D. anosmum orchids.  Coconut water concentration of 100 ml•l-1 was the best concentration for growth and multiplication of D. anosmum orchids, based on both shoots and roots growth, plantlet height and wet weight.
