From generation to generation over the centuries, people in all parts of the world have developed adaptive social-cultural institutions and strategies of natural resource management based on the intimate relationship they had with their environment. At present, recent global warming is threatening people?s lives. Unfortunately, climate change is a natural phenomenon which is neither easy to observe, nor to predict and anticipate accurately. In many places, local people can no longer rely on earlier experiences and existing socio-cultural institutions to adjust to unprecedented changes. We are in urgent need of specific efforts to re-interpret and enrich our knowledge of this natural phenomenon. However, this is not an easy thing to do. People from all kinds of levels and entities in society are simultaneously the cause and the victims of global warming. The problem becomes even more complicated because of various mutually-affecting dimensions like ethics, politics, power, economics, and justice. These are theultimate challenges scholars of the social sciences and humanities need to address seriously everywhere in the world, including in Indonesia. This article addresses the arguments of what scholars in the social sciences and humanities could and should do in response to climate change. Promoting a new paradigm and ethics in dealing with climate change is urgent and improvements in approaches and research methodologies are necessary. Learning from experiences gained from the way farmers in Java respond to climate change, the author argues that interdisciplinary research across social and natural sciences, and collaborative work with target groups is a promising and significant step (although scholars will have to face many challenges and constraints).

Abstrak :
Suatu penelitian tentang gelombang mikroseismik kelautan yang direkam di tiga tempat, yakni Baron, Wanagama, dan Prambanan telah dilakukan. Penelitian ini bertujuan untuk mengetahui sifat-sifat gangguan latar yang berupa gangguan mikrosesmik kelautan di Wanagama, yang ditimbulkan oleh aktifitas lautan India. Untuk merekam data telah digunakan suatu sistem pengumpul data digital 3 kanal (seismograf) portabel buatan lennartz mars-88/fd dan seismometer (juga buatan lennartz) LE-3d/5s, yaitu sebuah alat ukur gerakan tanah 3 komponen arah dengan periode 5 detik. Pengolahan data menggunakan perangkat lunak PITSA (programmable interactive toolbox for seismological analysis). Parameter yang dianalisis adalah spektrum, amplitudo, dan gerak partikel gelombang gangguan yang direkam di tiga tempat tersebut di atas. Hasil analisis menunjukkan bahwa gelombang mikroseismik kelautan mempunyai frekuensi dominan 0,15 Hz, dan berdasarkan spektrumnya mempunyai amplitudo yang mengecil kearah utara. Untuk wanagama, gangguan mikroseismik ini nampaknya agak terganggu oleh gelombang mikroseismik yang bersifat lokal.

Abstrak :
Mode Kopel Laut-Atmosfer di Daerah Tropis Samudera Hindia selama Tahun 2011. Mode kopel laut-atmosfer di kawasan tropis Samudera Hindia yang dikenal sebagai fenomena Indian Ocean Dipole (IOD) terjadi pada musim panas hingga musim gugur tahun 2011. Pada studi ini, data observasi satelit, data reanalisis, dan data dari hasil pengukuran arus laut digunakan untuk mengevaluasi terjadinya fenomena IOD di tahun 2011. Hasil studi menunjukkan bahwa fenomena IOD tahun 2011 merupakan jenis IOD yang lemah dan berdurasi pendek. IOD di tahun 2011 mulai terbentuk di bulan Juli, mencapai puncaknya di bulan September, meluruh di bulan Oktober dan menghilang di bulan November. Pada saat fase puncak, anomali suhu permukaan laut di dekat pantai Sumatera-Jawa mencapai -1,2 °C. Data observasi arus di tengah dan di sisi timur ekuator Samudera Hindia menunjukkan adanya respon laut terhadap anomali sirkulasi atmosfer. Hasil pengukuran menunjukkan bahwa arus zona bergerak ke arah barat sebagai respon terhadap angin timuran pada fase puncak IOD tahun 2011.
Coupled ocean-atmosphere mode in the tropical Indian Ocean, so-called the Indian Ocean Dipole (IOD), occurred during boreal summer to fall 2011. In this study, data from satellite observations and atmospheric reanalysis datasets together with data from ocean current mooring were used to evaluate the evolution of the 2011 IOD event. It is shown that the 2011 IOD was a weak and short-lived event. It developed in July, peaked in September, decayed in October and terminated in November. During the peak phase, maximum negative sea surface temperature anomaly off Sumatera- Java reached -1.2 °C. As oceanic response to easterly wind anomalies along the equator, the observed zonal currents in the central and eastern equatorial Indian Ocean also showed prominent westward currents during the peak phase of the 2011 IOD event.
