Abstract

Dengue Hemorrhagic Fever (DHF) disease represents one of the important public health problems in Indonesia and it often generates an extraordinary occurrence of vast number of deaths. The research aims to know environmental factors and public behaviors which have relationship to the existence of mosquitoes larvae in the work area of North Kuta Public Health Centre. The result of this research shows that the environmental factors which are related to the existence of mosquitoes larvae are air humidity (p=0.000), the existence of obstructive drainage (p=0.000) and the existence of containers (p=0.000). The public behaviors which are associated with the existence of mosquitoes larvae are attitude (p=0.001) and the actions of people (p=0.000). In conclusion, the environmental factors which are related to the existence of mosquitoes larvae are air humidity, the existence of obstructive drainage and the existence of containers. The public behaviors which are associated with the existence of mosquitoes larvae are attitude and the actions of people. It is suggested that the people should participate more in the prevention of DHF disease by removing the nests of mosquitoes, and the Public Health Departement should put more attention to the environmental factors which are associated with the existence of mosquitoes larvae.

Abstract

The objective of this article is to examine the ethnoecological study of "Satoyama" and to present in the form of descriptive case study approach and literature approach to collect reading materials which related in this object through the website of internet and some books. The meaning of Satoyama is the mountains near the village. The mountains are put in the ecosystem that is influenced by the life of the communities. Actually, since 5000 years ago inhabitant of Japan already knew and maintained their forests in harmony. They lived around the fields near the rivers. Approximately 2000 years ago they began to plant rice in their field. Harmonious relationship between humans, forests, land and water ran from year to year in tradisional ways, they utilized the environment as wise as they could. Such conditions made Satoyama as traditional wisdom of use. Due to population growing forest conditions gradually began to change. The forest encroachment and logging for building materials of the giant castles and fuel wood destroyed forest in Japan widely. With the development of science and technology the economic value of forest in Satoyama have been influenced negatively. In short since the early 1960s years Satoyama has no economic value anymore and the traditional wisdom Satoyama society began to fall down, so the economical thinking take precedence because the rapid growth of population and development science and technology. At this time many Satoyama areas have been changed shape and it has been converted to land for housing development on a large scale into the "New Town" by the big city like; "Senri New Town'' area of Northern Osaka "Tama New Town" area of Western Tokyo "Senboku New Town'' area of Southern Osaka

Abstract

Forest as an asset of national development is really beneficial for life and livelihood. It brings benefits ecologically, culturally, and economically on condition that the forest is properly exploited. For that purpose, forest should be managed, protected, and exploited continuously for the sake of the people's welfare, not only for the present but also for the next generation. Jompi Preserved Forest Area is one of the preserved forest areas in Muna Regency, which is now in very bad condition. The people living around the forest are powerless. This research aims: to formulate a model of community empowerment adjusted to the local condition. The technique of collecting samples used is cluster sampling, covering 226 heads of family. The analysis used is correlation analysis of Rank Spearman (r5), Multiple Regression, and Path Analysis. The result of analysis shows that the people's productivity and capability are still relatively low. This condition is resulted from the physical, human, and social capitals in the community. Similarly, the low capability of the empowerment facilitators and empowerment process also contribute to this situation. The effective empowerment model for the community around the preserved forest is the one that integrates the physical, human, and social capitals, and the facilitators' capability and empowerment process to create the power that can improve the productivity and capability of the community living around the Jompi Preserved Forest Area.

Abstract

Kepulauan Indonesia merupakan wilayah yang mendapatkan curah hujan sepanjang tahun, namun jaringan stasiun pengukuran curah hujan di wilayah ini tidak sepadat atau sebanyak seperti di benua besar lainnya. Oleh karena itu, satelit pengamatan curah hujan merupakan solusi terbaik untuk pengamatan dengan cakupan temporal dan spasial yang memadai. Tujuan dari penelitian ini adalah untuk validasi dan prediksi curah hujan bulanan berdasarkan data satelit Tropical Rainfall Measuring Mission Precipitation Radar (TRMM PR). Data yang digunakan adalah curah hujan bulanan dari satelit TRMM PR Level3A25 dan in situ data dari BMKG selama periode tahun 2004 - 2008. Hasil validasi menunjukkan bahwa data satelit memberikan nilai lebih rendah dari data observasi, kecuali di wilayah anti-monsunal ( C) dimana data satelit memberikan nilai lebih besar dari data observasi. Pola time series rata-rata hujan bulanan berdasarkan 39 lokasi selama periode lima tahun (2004-2008) menunjukkan pola yang sangat mirip dengan data observasi, dengan memberikan nilai korelasi yang tinggi (r = 0,82-0,98) dan RMSE (Root Mean Squared Error) kurang dari SO (mm/bulan). Hasil prediksi curah hujan bulanan dengan menggunakan metode ARIMA (Autoregressive integrated moving average) menunjukkan nilai yang lebih besar dari data observasinya dan pola curah hujan bulanannya untuk periode satu tahun (Januari-Desember 2009) memiliki pola kemiripan dengan data observasi.

Abstract

CFC refrigerant has been known to be one of causes of ozone layer diminishing and HFC is one of green house gases contributing to global warming through the leak and synthetic refrigerant waste to environment. As a response to the ozone layer diminishment on stratosphere, UNEP, in 1981, through a negotiating process of international stages of development reserve the ozone layer through Wina Convention legalized in March 1985. It was then followed up with Montreal Protocol in September 1987 consisting supervision rules on producing, consuming, and treading ozone damaging materials. The government of Indonesia had ratified the convention through President Decree Number 23 Year 1999. The ozone layer reservation program implementation in Indonesia is facilitated by KLH. Governor of Bali issued Decree Number 523/04-B/HK/2010 on membership restructuring of ozone layer reservation and ozone damaging materials control team work in province of Bali. This research was done in 27 car AC service companies or workshop, which received grant of 3R engine in Denpasar, Bali. The research was dominantly focused on monitoring and evaluation, that is how car AC service company or workshop manage CFC/ R-12 and HFC/R-134a refrigerant at service time using 3R engine that refrigerant does not escape to atmostphere. Cooling machine work procedure test (COP) was conducted in laboratory. Research result showed that car AC service company or workshop could manage CFC/ R-12 and HFC /R-l 34a eefctively ( 88,3%). The cooling engine work procedure using CFC /R-12 as the result of 3R engine recovery and recycel resulted in 2,435 while pure CFC/R-12 resulted in 2,54. There were differences in cooling engine work procedure to the use of pure CFC/R-12 refrigerant with that resulted by 3R engine with avarage difference 0,089 or 3,53%.

Abstract

Sex ratio is highly dependent on incubation temperature. The optimum temperature of 28 ° C - 30 ° C can result in sex ratio 1: 1. The high temperature will be produced predominantly female hatchlings, and vice versa. The incubation temperatures influenced by some environmental factors such as rainfall, air temperature, air humidity, sand temperature, sand humidity, sand type and vegetation. This research carried out at the Sukamade beach - East Java, Sangalaki island - East Kalimantan and Jamursba Medi beach - West Papua. Results showed the unbalanced sex ratio of sea turtle hatchlings in each of study area. The Sukamade beach generated 75% of male hatchlings in nests under vegetation, 100% female hatchlings in the nest on open beaches, and 87.5% male hatchlings in the hatchery. While the sex ratio of hatchlings produced on Sangalaki island are 100% male in nests under vegetation, 72.22% male hatchlings in the nest on open beaches and 94.44% male hatchlings in the hatchery. On the Jamursba Medi beach produced 90.9% male hatchlings from nests on open beaches. Based on correlation analysis, a significant correlation showed between sex ratio and incubation temperature with significance of 0.01. While there is no significance correlation showed between sex ratios by environmental factors, with significance of 0.942 for the air temperature variable, 0.340 for the air humidity, 0292 for amount of the rainfall, 0799 for the sand fraction, and 0.331 for the sand humidity. All of these significance are greater than 0.05.
