This research aims to analyse rain fluctuation and river morphology to flood concentration in Bengawan Solo River, Surakarta. The method of this research is field survey supported by secondary data analysis. The survey was conducted using GPS (Global Positioning System). The result indicates that high intensity rainfall in the research area happened during October till April. River flow in dry season generally decreased in accordance with the distribution of low rainfall (dry month). Whereas, river flow rates seen to increase along with the rainfall that occurs in the rainy season. Other result show that point 11-18 (location in Tanjung village district of Sukoharjo till Semanggi village district of Pasar Kliwon) very superficial which became impact of the river. The point represent floods concentration, therefore if there is rain with high quantity, the water will rise and overflow to surface, especially point 11, 13, and 16 (Tanjung, Kedunggudel, and Telukan village district of Sukoharjo). The processes that occurred at these sites are sedimentation, and lateral erosion (horizontal erosion).

This research was intended to know the cause of a drawdown of artesian groundwater surface and analyze on exploiting its groundwater in Surakarta. The total amount of groundwater exploitation in Surakarta will be 69,206.4 m3 if it is compared the groundwater runoff capacity of unconfined aquifer as with 8,860.9 m3 a day and confined aquifer as 42,447.3 m3 a day. Thus, the total amount of groundwater runoff in Surakarta is 51,308.2 m3 a day. Groundwater exploitation has exceeded the capacity of groundwater runoff as 17,898.2 m3, so the reservoir of groundwater is going to reduce continually. Groundwater exploitation in the loation of the researh has caused a piezometric drawdown. In 1990, its piezometric was negative, it means that the position of the piezometric was under the surface of land, while in 1990 artesian well indicated that its piezometric was almost nearly positive. Thus, the piezometric drawdown average 9.4 m3. In the center of the ity, it happened the cone of depression at piezometric contour in 1990, so a piezometric drawdown that resulted from groundwater exploitation exceeding the runoff of groundwater was proved. As a result of groundwater exploitation excessively, it resulted in the inequilibrium of groundwater. This depession has been extending continually as a result of adding wells, so it result in a groundwater drawdown permanently, as happened in the location of the research.

To comprehend the factors which influence on the juvenile water, it needs paying attention to the rocks permeability, the thickness of the aeration zone, the type of the material composition and the depth of the ground water. The grade of the ground water quality, both ground water in general and juvenile water in the urban, is dependent upon the natural physical, man made physical, and the condition of the local inhabitant besides the another factors. The influence grade of the factors are undersirable yet because among of them there are cross-linkages. The linkage of the ground water quality condition, besides another factor, inconfirmed by the inhabitant and the settelement. The aspect of the man made physical, both sanitation condition and the population density with their activity effect i.e. sewage by product, should fully determine the ground water quality. There is a closed connection between the juvenile water quality and the settlement condition, mainly, in the case is the domestic sewage disposal. It is estimated that the unit of settlement associates with the grade of the juvenile water quality. Some of the variabilities which are desirable to sustain the settlement condition and constitutes the influence variability i.e. the density of the population and buildings, and the condition of the drainage system for sewage.

Since people living in a karst area periodically face a crisis due to a lack of fresh water, it is necessary to re-evaluate the ability to use water resources. An appropriate and effective management is required to use available water resource sustainably. We describe a management process of exploring underground river in karst region as water resources. The activities completed included four phases, namely exploration, pre-lifting activities, the water lifting and post-lifting activities. The exploration phase included speleological surveys and data collection for the cave mouth using remote sensing instrument. The pre-lifting was done to prepare various requirements before the lifting process was completed. The water lifting phase consisted of the construction of an underground river dam, the installation of submersible pumps, the construction of reservoirs and the installation of piping to connect to the public hydrant. The post-lifting phase was mainly conducted to organise water distribution evenly. This management model was evidenced to successfully overcome drought in Pucung village by providing fresh water to the local community. Moreover, this model promoted residents’ cost savings by reducing their expenses for buying water from IDR 50,000/m3 to IDR 3,500/m3 (1,300 percent).

The quality of groundwater of unonfined aquifer with growing population density is endangered by population. This may cause serious problem as greatest portion of the population utility groundwater of unconfined aquifer as their drinking water. This research is aim at studying the difference in quality of groundwater of unonfined aquifer in Surakarta Munipicality by settlement units, and studying the impact settlement factors and groundwater depth on the quality of groundwater of unonfined aquifer. The research was executed by a survey methhod, taking 44 units of groundwater of unonfined aquifer samples at stratified proportional random from 44 villages. The samples were analyzed at the laboratory of Local Drinking Water Company (PDAM) of Surakarta. Data were analyzed using by stiff diagram, variance analysis, and multiple regression. The research reveals that there is very little differences in the quality of free groundwater in Surakarta, as it is shown by same chemical properties. Several chemical properties were found very high in concentration, but the rest were simultaniously low. On the basis of minimum quality of drinking water coli content have exeeded the allowed limit for drinking water.Among the settlement units observed, there were no significant differences in the physical, chemical (except pH), bacteriological factors. This means that differences among various depth of water. Electrical onductivity (EC), Na, Mg, H2CO3, H2SO4, and NH3 were found different among various depth of water table. Major chemical conentration were significant with geology formation. Population density, built up areas, size of settlement, building density, and the condition of drainage simultaniously affect the quality of free ground water. No differences among settlement units was observed the most important fators determining the free groundwater quality was population density.

Keberhasilan pembelajaran banyak dipengaruhi oleh kemampuan guru. Artinya, di pundak gurulah keberhasilan pembelajaran dibebankan. Sementara realitas yang ada dan terjadi di lapangan, ada kesan bahwa kemampuan guru masih rendah. Sebagian besar dari mereka masih berpredikat sebagai pelaksana kurikulum, bahkan diantara kegiatan-kegiatan yang mereka lakukan lebih bersifat rutinitas. Guru belum siap menghadapi berbagai perubahan, di samping terbatasnya akses pada materi pembelajaran mutakhir. Motivasi dan kesiapan belajar peserta didik juga rendah. Kurangnya waktu belajar, lingkup materi yang sangat luas, serta laju/akselerasi perubahan (change) di bidang ilmu, teknologi dan seni berjalan begitu cepat. Mata pelajaran geografi mulai tahun ajaran 2008/2009 adalah salah satu materi ujian nasional, sehingga diperlukan peningkatan kualitas guru geografi untuk menunjang proses pembelajarannya. Pendidikan dan pelatihan SIG di kalangan guru-guru yang tergabung dalam Musyawarah Guru Mata Pelajaran(MGMP) Geografi, dengan peragaan dan praktek dibarengi simulasi GIS diharapan akan dapat memperlancar dan mempermudah proses pembelajaran geografi khususnya SIG. Bahwa melalui media pendidikan dan keterampilan SIG akan dapat terjalin kerja sama yang erat antara Fakultas Geografi dengan stake holder (sumber input mahasiswa baru) dengan harapan akan semakin meningkatkan minat belajar ilmu geografi di kalangan masyarakat, khususnya kepada peserta didik atau siswa-siswa smu tempat guru anggota MGMP Geografi tersebut bekerja . Hasil kegiatan ini adalah peserta Guru-guru Geografi mampu membuat peta tematik yang merepresentasikan wilayahnya yaitu Kabupaten Karanganyar dan Kabupaten Sragen. Luaran peta tematik dalam bentuk hardcopy dan softcopy.

Nilai serapan karbon ekosistem di kawasan perkotaan jarang diteliti karena kurangnya vegetasi sebagai media penjerap karbon. Padahal kawasan perkotaan memiliki tingkat emisi karbon tinggi yang harus diminimalkan jumlahnya. Di sisi lain, nilai serapan karbon di kawasan perkotaan sangatlah dinamis akibat adanya faktor alami dari lingkungan dan faktor non-alami akibat aktivitas antropogenik. Tujuan dari penelitian ini yaitu untuk mengidentifikasi nilai serapan karbondioksida di kawasan perkotaan dan untuk mengetahui variasi spasial nilai serapan karbon di kawasan perkotaan selama setahun. Hasil menunjukkan bahwa nilai serapan karbon di kawasan perkotaan tropis memiliki nilai yang cukup besar dibandingkan kawasan perkotaan di iklim sedang. Hal ini terjadi karena masih adanya ruang terbuka hijau berupa kebun di lahan pekarangan dan lahan pertanian.

The need for built-up areas continues to increase, along with the increasing population in the city of Surakarta and its surrounding. This condition affects the land surface temperature which then leads to the change in climatic conditions. The availability of land for settlement and surface temperature will affect the comfort level of living in a city. For this reason, this study aims to map the distribution of built-up area and the surface temperature of Surakarta city and discusses the relationship between these two aspects spatially and temporally. The data used are Landsat imageries recorded in 2000, 2013, and 2019. The built-up area was identified using Normalized Difference Built-Up Index (NDBI), while the temperature data was obtained through thermal band processing using Land Surface Temperature (LST) method. The results showed that during the period of the study, the built-up area and the surface temperature in Surakarta and its surroundings increased, especially in the eastern and southern parts of Surakarta. The results also showed that there is a positive correlation between the built-up index and its surface temperature.
