Abstract

Radar is able to provide information about extreme weather observations in the form of heavy rain, so it is important to find the level of accuracy of the radar in providing extreme weather information. So that with accurate data disaster mitigation can be done by creating an early warning system using radar data in order to minimize the impact that will occur. Comparative analysis of the estimated rainfall events on the radar with surface observation data shows a good level of accuracy, but the blankness of the data on the radar due to damage thus influences the decision making of the forecasters when providing extreme weather information quickly to the public. By knowing the radar accuracy level is quite good in estimating rain events, BMKG can provide weather information in the form of appropriate early warning so that people can anticipate extreme weather events

Abstract

The study is aimed at describing and analyzing the impact of regional extension on the economical aspect of Papua Province based on the indicators of public welfare such as per capita income, poverty, and interregional gap. By separating two time periods between before and after extension, and using average differential test, or t-test equal mean, it is estimated that regional extension policy significantly does not bring the per capita income to higher rate than before extension. In other word, statistically, there is no difference between per capita income between before and after extension. It is said that regional extension does not influence the per capita income. The strong significant indication shows that regional extension affects the decreased rate of urban poverty. It is, however, failed to reduce the rural poverty. In general, regional extension has significant effect on the reduction of poverty in Papua Province. Finally, regional extension policy is not statistically stronger, or less significant, to influence the interregional development gap in Papua Province. Based on the statistic result, it is generalized that regional extension policy in Papua Province has significant effect on the poverty reduction in Papua Province.

Abstract

AbstractThe huge amount of rice straw as by-product of rice production system and the potential useof it as raw material of compost production for organic rice cultivation was the backgroundof this research. Here, rice straw was concerned as raw material to produce compost insteadof as waste from rice cultivation. The objectives of the research were to implement theconcept of “Zero waste production management” in agriculture by composting rice strawgenerated from an experimental field; to develop an input-output (waste-compost) massbalance in organic rice cultivation system; and, to apply the resulted compost on the ricefield. Materials necessary for the research covered an experimental organic rice field locatedin Bogor Municipality, rice seed, rice straw and goat manure. The rice field obtained organicfertilizer merely from compost without any synthetic fertilizer. The produced rice straw andgoat manure were composted by natural static pile method. The result of the researchindicated that waste-compost mass balance based on one hectare rice field showed that theproduced straw was ± 14.1 ton and the resulted compost was around 11.3 ton. It is merely 7ton from the produced compost necessary to apply in one hectare of rice field according toThe Ministry of Agriculture recommendation. It can be concluded that if the entire ricestraw produced from one hectare of rice field was composted, then the rice field could becompost self sufficient and even the rest of 4.3 ton could be utilized for other purposes.

Abstract

In order to avoid post power syndrome, the elderly who have a hobby of farming / gardening can be empowered through the introduction of LOF (liquid organic fertilizer) making technology and its application. The aim is for the elderly to understand the technology of making organic fertilizers that are lightweight, useful and entertaining as well as for them to feel contribute in maintaining the environment. The training method applied is a combination of interactive lecture and practice methods. Based on these methods, have succeeded in growing their creativity in making LOF and feel comforted on the results obtained. Successful LOF products contained nitrogen, phosphorus and potassium (NPK) of 146,701 mg / L, 0.741 mg / L, and 0.035 mg / L, respectively, and magnesium (Mg) and calcium (Ca) of 86.332 mg / L and 1.970 mg / L. The application of LOF products has been done on the orchid plants (Phalaenopsis amabilis) with satisfactory results. Thus, the mastery of LOF making technology and its application will reduce the dependence of chemical fertilizer use and replace it with homemade organic fertilizer so it can contribute in maintaining health and environmental sustainability.

Abstract

Rainfall-runoff transformation of a watershed is one of the most complex hydrology phenomena, nonlinier process, time-varying and spatial distribution. Rainfall-runoff relationships play an important role in water resource management planning and therefore, different types of models with various degrees of complexity have been developed for this purpose. The application of Artificial Neural Networks (ANNs) on rainfall-runoff modelling has studied more extensively in order to appreciate and fulfil the potential of this modelling approach. Back propagation method has used in this study for modelling monthly rainfall for small size catchments areas. ANN model developed in this study successfully predicts relationship for rainfall-runoff with 90.14% accuracy on learning process and 72.41% accuracy on testing process. These results show that ANN provides a systematic approach for runoff estimation and represents improvement in prediction accuracy.

Abstract

Lake Markermeer is a large fresh water lake in the centre of the Netherlands. The actual problem in this lake was its high turbidity. Since Lake Markermeer is categorised as a shallow lake, it is very susceptible for water quality problems. The general objective of this study was to study water quality of Lake Markermeer. Monitoring of water quality was carried out in a 5 months period from November, 2007 until March, 2008. For this research, surface water was firstly sampled at 66 representative sites; parameters measured were: pH, EC, temperature, turbidity, DO, Secchi depth, P total, N total, chlorophyll and Silica total. The monitoring was continued every two weeks at two fixed sampling sites referred to as STA and STB with the same previous parameters excluding total. Statistical t-test analysis was utilised to compare the value of each parameter between two sampling stations. Result of water quality measurement showed that variability of surface water quality in the Lake Markermeer could be explained as follows: for pH, conductivity, temperature and dissolved oxygen (DO) no significant variation was found among sampling sites (coefficient of variation, CV ? 10%). On the other hand, for turbidity, Secchi disk depth, P total, N total, chlorophyll-a and silica total, ranges between minimum and maximum values were significantly larger (CV > 10%). The result of the turbidity, Secchi disk depth, N total, P total and chlorophyll-a at the two fixed sampling stations were much diverse during the sampling period.
