Abstract

Fourteen compounds were isolated from acetone extracts of three species of seaweeds (Eucheuma serra, a red seaweed, Halimeda opuntia, a green seaweed, and Hydroclathrus clathratus, a brown seaweed) using bioautographic TLC methods and identified using GC-MS. From Eucheuma serra were isolated 8 compounds (3 fatty acids, 3 steroids, and 2 aldehyds). Only two compounds of fatty acid camefrom Halimeda opuntia, whereas Hydroclathrus clathratus produced 6 compounds (4 fatty acids, one compound each of steroid and ether). All isolated single compoundswere tested for their antibacterial activities by the agar diffusion method against the Gram-positive bacteria Staphylococcus aureus, Bacillus subtilis and Streptococcusfaecalis, and the Gram-negative bacteria Echerichia coli, Pseudomonas aeruginosa and Salmonella typhimurium. All 14 compounds showed activity against Gram-positivebacteria, especially Bacillus subtilis, and only 2 compounds showed activity against Gram-negative bacteria Escherichia coli. Nine compounds showed activity against Staphylococcus aureus, and 4 compounds showed activity against Streptococcusfaecalis. All compounds were not active against Pseudomonas aeruginosa andSalmonella typhimurium bacteria. This study indicated that there is indeed a diversityboth in kinds and in molecular structures of the antibacterial substances.

Abstract

This study was conducted by collaboration between BPPT, Chugoku Electric Power, and PT Indonesia Power and funded by GEC (Japan-Geo Environment Center). The study was started on August 2005, and finished on September 2006. The purpose of the study was to explore the unutilized potentials micro hydro power plants (MHPP) in Banjarcahyana irrigation channel. These sites are located at south eastern of Banjarnegara city. Development of these MHPP will be planned put into Clean Development Mechanism (CDM), therefore operation of these power generation would be calculated to reduce global warming effects. According to the study result, it was found eight locations having potential to build as MHPP. The development of the project economically feasible estimated could reduce 17,252 t-CO2 of Green House Gas Effect annually. This study also provides new emission coefficient factor for electricity grid system of Jawa Bali Madura (JAMALI).

Abstract

Pada skala nasional DAS Citarum tergolong DAS super prioritas. Khusus DASCitarum Hulu mempunyai fungsi utama sebagai perlindungan tata air tetapi dalamperkembangannya mempunyai fungsi ekonomi yang sangat strategis.Perkembangan kota dan jumlah penduduk di dalam DAS Citarum Hulumenyebabkan kebutuhan akan air bersih meningkat sangat tajam. Sebagian besarkebutuhan tersebut diambil dari air tanah. Dengan semakin meningkatnyakebutuhan (pengambilan) air tanah dan di lain pihak kualitas ruang hidrologinyasemakin menurun, akan mengakibatkan terjadinya ketidakseimbangan antarapengambilan dengan pemasokan (imbuhan) air tanah. Akibat ketidakseimbangantersebut antara lain adalah turunnya muka air tanah, turunnya produksi sumur bor,frekuensi banjir di musim hujan dan frekuensi kekeringan di musim kemarausemakin besar. Oleh karena itu diperlukan adanya konservasi daerah resapan airdi DAS Citarum Hulu dari desakan perkembangan kawasan urban. Salah satuupaya untuk mendukung konservasi daerah resapan air tersebut adalah dengandikeluarkannya berbagai peraturan perundangan baik tingkat nasional maupunkabupaten. Beberapa hal penting berkaitan dengan perauran perundanganmengenai daerah resapan air di DAS Citarum Hulu adalah : a) Sebenarnyaperaturan atau kebijaksanaan untuk mempertahankan fungsi ekologi daerahresapan air sudah memadai, tetapi sering informasi dan batasannya kurang jelasdan rinci; b) Kurang terkendalinya pembangunan pemukiman oleh perorangankarena umumnya peraturan diberlakukan untuk pembangunan pemukiman dalamskala besar oleh pengembang (developer) serta peraturan/ kebijaksanaan yangdibuat sering belum dilengkapi peta yang representatif dan applicable;c)Kurangnya pranata (sistem) yang baik dan kuat, kuantitas dan kualitassumberdaya manusia yang terbatas, serta biaya dan waktu yang terbatas pulasehingga dalam proses pelaksanaan dan pengawasannya sering terjadipenyimpangan.

Abstract

Groundwater quality, espicially shallow groundwater is very vulnerable topollution from residence, urban, agriculture, and industrial activity. All ofthe activity, to result waste and pollutant potentially, that can degradegroundwater quality, like as in southern coast of Bantul Resisence-Yogyakarta. So, it’s need modeling of vulnerability of shallow groundwaterin unconfined aquifer. Based on natural condition of southern coast ofBantul Residence, parameters are used in development this model aredepth of groundwater level, surface geological condition, soil condition, andaquifer media.Based on this model, vulnerability of southern coast in Bantul Residence, is: abaut 27,86 km (47,52%) is classified in vulnerable class, 16,23 km (27,69%) is very vulnerable, 5,49 km (9,37% is, poor vulnerable and 9,04 km (15,42%) is not vulnerable. Generally, groundwater vulnerability is degrade toward land.

Abstract

Makrozoobentos adalah biota yang hidup di dalam substrat maupun menempel di permukaan dasar perairan. Makrozoobentos memiliki peran penting dalam eksositem akuatik, yaitu sebagai sumber makanan biota perairan dan sebagai detritus. Tujuan penelitian ini adalah untuk mengetahui keanekaragaman makrozoobentos di Situ Gintung, Situ Bungur dan Situ Kuru. Titik pengambilan sampel terdiri dari 5 stasiun dengan masing-masing 3 ulangan. Faktor fisik kimia makrozoobentos diuji dengan t-test. Hasil t-test menunjukkan di Situ Gintung dan Situ Bungur hanya nilai pH yang berbeda (p<0,01), sedangkan Situ Kuru memiliki kondisi fisik kimia yang berbeda dengan Situ Gintung dan Situ Bungur (p<0,01). Makrozoobentos yang ditemukan di ketiga lokasi pengamatan seluruhnya terdiri dari 10 famili dan 16 jenis. Makrozoobentos dari jenis P. canaliculata terlihat mendominasi pada lokasi Situ Gintung. Sedangkan pada lokasi Situ Kuru jenis T. tubifex ditemukan lebih mendominasi. Nilai indeks keanekaragaman (H’) di Situ Gintung (1,74) dan Situ Bungur (2,29) yang tergolong sedang, mengindikasikan kedua perairan tercemar sedang. Sedangkan nilai indeks keanekaragaman Situ Kuru (0,92) yang rendah, mengindikasikan perairan tersebut tercemar berat.Kata kunci : keanekaragaman, makrozoobentos, Situ Gintung, Situ Bungur, Situ Kuru

Abstract

Experiment using organic fertilizer and microbial community to support the growth of Tectona grandis L.f in the cyanide contaminated-soil has been conducted in gold tailing pond Cikotok. Microbes used in this experiment were mixed of cyanide degradingbacteria,Nitrogen fixing-bacteria, and Phosphat solubilizing-bacteria. The results show that the microbes given in the Tectona grandis L.f plantation was significantly supporting the growth of the plants and reduced cyanide from the contaminated soil, but did not influence the microbe population of the soil.Key word: Phytoremediation, Cyanide, Tectona grandis L.f.

Abstract

An experiment on the utilization of nitrifying bacteria in shrimps pond ecosystemwas conducted in the village of Grinting, Brebes Regency. This experiment hastwo treatment ponds. Pond A was put nitrifying bacteria on as a treatment andpond B was without its treatment. The impact of the treatment was indicated by ammonia concentration measured, in which pond A was lower than pond B. In other words proved that nitrification process in pond A ecosystem was accelerated by the addition of nitrifying bacteria.
