Abstract

The issue dealing with climate changes has been becoming more stressed out along with more frequent of the occurrence of extreme weather as a consequence of anomaly climate. Examples of anomaly climate that often related to extreme weather are El Nino and La Nina. One of methods to find out the condition of El Nino and La Nina is by observing SOI values. Methods utilized in this research were by collecting rainfall data and SOI values along with regresion analyses to observe the determination coefficient values (R2). Results of this research showed that the rainfall variability on the research area did not affect fluctuations of SOI values on rainy seasons except in Munduk, while on dry seasons it was very clear shown, except in Gitgit. On the transition period, the influence of SOI values on rainfall variability was seen differ on every rain stations. On the first transition period (April), the fluctuation of SOI values had seen clearly being influenced on Baturiti?s rain station and was not influenced on Gitgit?s rain station. On the second transition (October), the influence of SOI values has affected Munduk rain station and did not influence that on Candikuning rain station. The research?s location that covered an area with monsoon rain paterns, the presence of Walker cycles, and ITCZ were also affected the results.The position of rain stations on a certain topography or location also influenced rainfall variability, so it can cause the difference on SOI values on each season.

Abstract

Studi ini meneliti pengaruh faktor-faktor lalu lintas lokal terhadap tingkat kebisingan di jalan arteri di Bali dengan studi kasus jalan Bypass I Gusti Ngurah Rai dan Sunset Road. Model regresi sederhana dan regresi berganda disusun dengan variabel-variabel volume dan kecepatan lalu lintas serta nilai kebisingan yang diperoleh dari hasil pengukuran tingkat kebisingan di kedua jalan arteri tersebut. Model yang disusun terdiri dari 1 variabel tidak bebas dan 8 variabel bebas menggunakan perangkat lunak SPSS versi 15. Hasil studi ini menyimpulkan bahwa volume lalu lintas dari sepeda motor dan jarak pengamatan kebisingan dari garis tengah jalan terdekat sangat berpengaruh terhadap tingkat kebisingan. Volume sepeda motor berpengaruh sebesar 26.7% terhadap tingkat kebisingan dan gabungan volume sepeda motor dan jarak pengamatan kebisingan dari garis tengah jalan terdekat berpengaruh sebesar 46.9% terhadap tingkat kebisingan. Semakin besar volume lalu lintas dari sepeda motor semakin tinggi pula tingkat kebisingan. Kebijakan di bidang transportasi seperti pengurangan jumlah sepeda motor di jalan raya dan pada saat yang bersamaan memperbaiki kualitas angkutan umum merupakan alternatif untuk mengurangi tingkat kebisingan. Penelitian ini juga menyarankan suatu studi lanjutan untuk menentukan jarak pengamatan yang ideal dari garis tengah jalan pada saat pengukuran tingkat kebisingan di jalan.

Abstract

The objectives of research were to obtain basic information on: 1) pesticide use by Tegal farmers, 2) knowledge, attitude and practices of farmers on pesticide, 3) the relation between knowledge, attitude and practices of farmers on pesticide and intoxication level of farmers. Knowledge-attitude- practice (KAP) survey was conducted on 90 farmers (30 chili farmers, 30 shallot farmers, 30 rice farmers) of Tegal District with structured questionnaire. The information collected included private data, type and number of pesticide uses, knowledge on pesticide, practices and attitude in pesticide uses, and symptom rose after pesticide application. The locations of survey were in Sub-district Surodadi for farmers rice, Dukuhturi for shallot farmers and Bumijawa for chili farmers. The data was grouped and calculated for percentage. Further analysis was conducted by cross tabulation and continued by Ï?2 test for independence of variables. Five most frequently used pesticides by farmers in Tegal were pesticides with active ingredient chlorpyrifos, profenofos, alphamethrin, deltamethrin and propineb, respectively. Knowledge, attitude and practices of most Tegal farmers on pesticide management is still low and not in line with Integrated Pests Management principles. Moreover, KAP level from the best to the worst was chili farmers, paddy farmers and shallot farmers respectively. Intoxication level based on self report, from the most severe to the least was shallot farmers, chili farmers and paddy farmers respectively. There was significant relation of knowledge and practices of farmers and pesticides intoxication level.

Abstract

In Indonesia, there are 5.590 main rivers, 65.017 tributaries, and 500 lakes (Status LingkunganHidup Indonesia, 2010). Ironically, the rivers? surroundings and watershed have facedenormous pressure since years ago because of they became the center of the development ofcivilization as well as the center of communities? social-economic activities. Furthermore, theanalysis to 40 watersheds in West Java indicated the decline of hydrological functions. 14watersheds can be categorized as extremely critical, while 8 watersheds considered to becritical. The same situations are believed to occur all across Indonesia.The Basic Competence of Sociology for Social Sciences Specialization in High School,contained the demand for students to able to design, implement, and report communitydevelopment action by using local wisdoms as foundation in the globalization era. From thisbasic competence, it is so appropriate to try to formulate an empowerment action for womenas watershed conservationist, with high scholl students as facilitators. Why womesn ? Theanswers mostly related to gender stereotypes associated to women, such as gentle, sensitive,patient, and full of considerations. The stereotypes  will enable women to conservate as wellas using the environment continuously. Or by other words, women are assumed to have theability to improve welfare without ruin nature.

Abstract

The need better understand the linkages and interdependencies of socio-economic and coastal environmental dynamics has taken on a more deliberate role in the development and assessment of Integrated Coastal Management on Batudaka islands. The DPSIR (drivers- pressures - states - impacts - responses) framework was used in scoping biodiversity management issues and problems. DPSIR model is to analyze the causative factors of pressure on the ecosystem of small islands and recommendations for environmental restoration effort. Results of the study showed that population and economic (tourism and fisheries demand) driving forces causing ecosystem vulnerable.  Land conversions, domestic waste, other pollutant was pressured this area, while increasing driving forces. The State environmental as waters quality is still relative well for tourisms and fisheries activity, physical impact as abrasion and sedimentation, habitat loss and biodiversity changes at 2000 until 2010 year at Batudaka Islands increase life coral and mangrove, decrease seagrass. Impact to environment  i.e. water abstraction,  sediment water fluxes across  coastal zones, change of habitats and biological diversity can be caused decreasing of coastal ecosystem. Functional diversity can be defined as a variety of different responses to environmental change, in particular the variety of spatial and temporal scales with which organisms reach to each other and to the environment.

Abstract

Peningkatan CO2 di atmosfer yang berpotensi menghasilkan pemanasan global telah menjadi perhatian bagi kehidupan manusia. Lautan mengandung lima puluh kali lebih besar CO2 daripada atmosfer dan menjadi penyangga yang membatasi konsentrasi CO2 dalam atmosfer. CO2 mengalami perubahan secara terus menerus antara udara-lautan dan konsentrasi CO2 di dalam laut dikendalikan oleh parameter fisika, kimia, dan biologi. Perubahan konsentrasi CO2 antara udara-lautan dapat ditentukan dari interaksi gas dan perbedaan konsentrasi CO2 antara udara-lautan. Perubahan CO2 antara udara-lautan dapat dikaji dari studi kecepatan angin, koefisien gesekan kecepatan angin yang diperoleh dari satelit ALOS/PALSAR di daerah Selat Badung dan Selat Lombok, salinitas, dan juga dengan SST yang diperoleh dari satelit MODIS. Hasil analisis menunjukkan bahwa koefisien perubahan CO2, perbedaan tekanan CO2 antara udara-lautan, dan CO2 flux antara udara-lautan secara berturut-turut yaitu 0.303±0.006 (rata-rata±standar deviasi) (mol m-2 month-1µatm-1), 17.94±10.79 ?atm, and 5.35±3.26 (mol m-2 month-1), dengan nilai maksimum dan minimum dari koefisien perubahan CO2 secara berturut-turut terjadi pada bulan Agustus dan Februari.

Abstract

Forest has an opponent function in climate change issue, as carbon sink and carbon source. Reducing emission from deforestation and forest degradation (REDD) is the mechanism to tackle green house gas emission from forest sector. The economic analysis of those projects in Indonesia has not conducted yet, moreover the benefit and cost analysis of REDD on forest management unit. The research was conducted in the unique site, at Industrial Forest Plantation PT. SBA WI, South Sumatera. Benefit and cost analysis and break-even cost analysis were conducted to evaluate project feasibility. The research result shows that forest management was not feasible if the role of the project aimed to product wood or reducing emission only which conducted in mutual. If the project aims to reach both roles together, it is very attractive. Break-even cost of reducing emission and carbon sequestration in PT. SBA WI Rp.29.000,- per ton CO2e equal to US$3,17. It was lower than the cost in Bolivia, Ghana, and Nepal and also cheaper than carbon price in voluntary market.

Abstract

Eksistensi subak sebagai warisan budaya mulai terancam akibat alih fungsi lahansawah yang terus meningkat sejalan dengan pesatnya laju pembangunan, terutama disektor pariwisata. Alternatif yang dapat ditempuh untuk menekan alih fungsi lahan sawahyaitu  melalui optimasi penggunaan lahan dengan menerapkan usaha tani bernilai tinggi,seperti hortikultura untuk konsumsi hotel dan tanaman obat. Agar perencanaanpengembangan komoditas pertanian dapat dibuat akurat dan efektif,  maka perlu didukungdata karakteristik lahan yang yang lengkap dan mutakhir. Tujuan penelitian ini yaituuntuk mengevaluasi kesesuaian lahan untuk pengembangan komoditas tanamanhortikultura dan obat, dan menyusun arahan pertanian perkotaan berbasis lingkungan,peluang pasar, dan perlindungan subak.Metode yang digunakan dalam penelitian yaitu survey lapangan dengan subak sebagaiunit pengambilan sampel. Sifat-sifat tanah dianalisis dengan metode analisis tanah yangtelah baku berlaku di laboratorium. Kelas kesesuian lahan ditentukan berdasarkan faktorpembatas minimum dengan matching system yaitu membandingkan antara kualitas lahandengan persyaratan tumbuh tanaman menurut Zainudin, dkk., 1997. Arahan penggunaanlahan disusun berdasarkan kelas kesesuaian lahan tertinggi, konsevasi subak, dan filosofibudaya Bali.Hasil penelitian menunjukkan, bahwa kesesuaian lahan untuk padi tergolong sangatsesuai (S1), untuk sayuran, buah-buahan, dan tanaman obat tergolong sesuai (S) dengandua faktor pembatas yaitu drainase buruk dan tekstur tanah halus. Dalam pengelolaantanaman tersebut diperlukan pembuatan saluran drainase untuk memperbaiki drainasedan penambahan bahan organik untuk memperbaiki tekstur tanah. Arahan penggunaanlahan pertanian di Denpasar, pada musim hujan diprioritaskan untuk bertanam padimengikuti pola rotasi tanaman dan zonasi penanaman komoditas pertanian, seperti jenisbunga-bungaan di bagian utara, jenis buah-buahan dan sayuran di bagian tengah, sayurandan tanaman palawija di bagian selatan.

Abstract

Research on isolation and identification of lipid degrading bacteria in some sewage disposing sites and Denpasar Estuary Dam was carried out in April, 2006. This research aims to identify fat degrading bacteria on those areas.Isolation of bacteria was undertaken using thinning methods (platting methods) grown at sierra media. Colonies observed on the media after incubation on the temperature of 30-370C for 24 hours were identified based on macroscopic observations, biochemical tests, microscopic and cross tests to ensure that the bacteria identified was absolutely lipid degrading bacteria.The research result showed that number of lipid degrading bacteria isolates obtained from three sampling sites were 7 isolates. Four isolates were obtained from samples taken on BTDC Lagoons, the samples of which contains Bacillus sp. (A). Bacillus sp. (B), Klebsiella sp. and Staphylococcus sp., 2 isolates were gotten from samples found in estuary DAM with bacteria of Bacillus sp. (A) and Klebsiella sp. and 1 isolate was gotten from slaughterhouse waste disposal with Klebsiella sp. bacteria. Cross test results carried out on the seven isolates showed that two genera of bacteria only, namely: Bacillus sp. and Pseudomonas sp., which were viable after inoculation and 24 hours of incubation time.
