Urban Heat Island dan Upaya Penanganannya
Abstrak: Fenomena urban heat island (UHI) merupakan suatu fenomena yang banyak di kaji oleh para
pengkaji iklim di dunia, termasuk di Indonesia. Fenomena ini ditandai dengan semakin meningkatnya suhu kawasan pusat kota dibandingkan dengan kawasan di sekitarnya . Berdasarkan beberapa penelitian diketahui bahwa fenomena ini merupakan salah satu sumber utama yang menyebabkan terjadinya peningkatan suhu bumi atau pemanasan global (Tursi lowati, 2012) . Fenomena ini terus meningkat seiring dengan terjadinya urbanisasi dan pertumbuhan kota. Oleh karena itu, perlu dilakukan upaya sepert i pengadaan green open space (GOS ) , dinding putih atau atap putih bagi rumah dan kantor, roof gorden , dan lain-lain. Hal tersebut dilakukan untuk menekan laju peningkatan fenomena tersebut

This research is initiated by the students’ reasoning and disposition which tend to be low and negative in learning mathematics. This research aims to compare whether students taught using guided discovery learning model perform better in mathematical reasoning and disposition compared to students taught using conventional learning model. This research employed quasi-experimental design involving 62 fifth grade students from two different elementary schools in Lembang. The data were collected by utilizing a test, a questionnaire and an observation sheet. The data obtained from the test and questionnaire were analyzed statistically using T-test to see two different average values and the data obtained from the observation sheet were analyzed qualitatively in order to look into the teaching and learning process performed by the students and teacher using guided discovery learning model. The result of the analysis and t-test showed that there were two different average scores in which the students taught using guided discovery learning model achieve higher scores in terms of mathematical reasoning and disposition compared to students taught using conventional learning model. The observation sheet also showed that the students’ learning activities have increased in each meeting. As a result, the implementation of guided discovery learning model can improve the mathematical reasoning and disposition of the fifth grade students of elementary schools. This research strongly recommend that the guided discovery learning model should be implemented to improve the students’ mathematical reasoning and disposition.

TEMPERATURE TREND ANALISIS IN JAKARTA CITY: 1981-2010
Abstract: The phenomenon of the increase in temperature is one object of study microclimate. This phenomenon occurs, in almost all major cities in the world, including in the city of Jakarta. The study was conducted in Jakarta by using secondary data for 30 years (1981-2010) at three stations namely Kemayoran, Pondok Betung, and Serang. The results showed a highly significant increase in temperature, especially in Kemayoran stations with R2= 0975, and the Pondok Betung station with R2= 0.972 at confidence level of 0.01. Meanwhile, the Serang station value is R = 0324. Significant temperature increase mainly occurred on minimum temperature impact on decreasing the temperature of max-min especially at Kemayoran Station with R2= 0394 on the confidence level of 0.01. Meanwhile, the station is Pondok Betung and Serang less significant with each value of R2 = 0.06 and 0.055 at 0.05 level. Significant temperature increase primarily in downtown and the suburbs, indicating the need for mitigation efforts both by the government or the local community. This is done to reduce the rate of increase in temperature in the city of Jakarta
RAINFALL SEASONALITY INDEX FOR SOUTH SULAWESI PROVINCE, INDONESIA, 1982-2012
ABSTRACT
Spatial and temporal variability of rainfall for any region in the world are very important with regards to planning for various sectors including water supply and agriculture demands. The aims of this paper are to study the spatial and temporal variability of seasonality of rainfall and its relation to rainfall regimes within the South Sulawesi Province, Indonesia. Data for the 64 rainfall stations for the 29 years (1983 – 2012) were used in order to calculate the SI for the whole of the South Sulawesi area. In general, the result showed that the dominance SI was the seasonal rainfall regime of 0.60 to 0.79 especially in the central region of the South Sulawesi. Furthermore, the rainfall regimes of rather seasonal with a short drier season (0.40 – 0.59) and markedly seasonal with a long drier season (0.80 – 0.99) were calculated for the northern part and Western part of the South Sulawesi Province, respectively. One significant finding was that the entire province did not experience a rainfall regime of very equable and equable but with a definite wetter season. However, a more extreme rainfall regime of ≥ 1.0 (3 months or less rainfall) was calculated for the southern part of the South Sulawesi Province. The rainfall data were divided into three periods with the 1983 – 1992 and 2003 – 2012 periods showed a more rather seasonal with a short drier season (0.40 – 0.59). For the period of 1993 – 2002 the dominance SI was seasonal rainfall regime. Based on these findings, it is clearly indicated that certain region of the South Sulawesi Province, especially for the southern part experienced a longer drier season in a single year, implying that the region could be experienced less water supply for domestic as well as for the agricultural sectors

Dengue hemorrhagic fever (DHF) is still one of the most important public health problem in Indonesia. Disease control efforts have been widely carried out, such as larvaciding, fogging focus, and mosquito breeding control. The efforts will be performing well if its involves community participation. The objectives of this study was to enhance community participation in the implementation of the mosquito control program of Dengue Hemorrhagic fever in Palupi and Singgani villages, Palu. The research design is a quasi experimental to analyze the difference between two approach, i.e. larvae surveyors (in Indonesia called as Jumantik) empowerment and the participation of the community leadres (in Indonesia called Ketua RT). Mosquito larvae survey was conducted with a single larval method. The population in this tsudy is all house in the two villages. Sample are consist of 100 houses in each village which were randomly selected. The result showed that during the first larvae survey in Palupi village, the larva-free rate (ABJ) was 68% with the result of CI, HI and BI were 20.81%, 32% and 46 respectively. In the village of Siranindi, the number of larva-free rate was 78%, with CI 19.64%, HI 22% and BI 33. At the seven weeks after the intervention with community participation suggests that the larva-free rate in Palupi village was became 89%, with the number of CI 3.67%, HI 11% and BI 1%. While in Siranindi village, the larva-free rate was 85% with the CI, HI and BI were 8.4%, 15% and 21% respectively.
