The southern Sumatera region experiences one rainy season and one dry season in a year associated with seasonal change in monsoonal winds. The peak of rainy season is occurring in November-December-January during the northwest monsoon season, while the dry season comes in June-July-August during the southeast monsoon season. This study is designed to evaluate possible influence of the coupled ocean-atmospheric modes in the tropical Indo-Pacific region, namely the El Niño-Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD) on the rainfall variability over the catchment area of the Music Basin, South Sumatera. The ENSO and IOD occurrences were reflected by the variability of sea surface temperature (SST) in the tropical Pacific and Indian Ocean, respectively. During El Niño and/or positive IOD episode, negative SST anomalies cover the eastern tropical Indian Ocean and western tropical Pacific including the Indonesian seas, leading to suppress convective activities that result in reduce precipitation over the maritime continent. The situation is reversed during La Niña and/or negative IOD event. The results revealed that the high topography area (e.g. Bukit Barisan) was shown to be instrumental to the pattern of rainfall variability. During the 2010 negative IOD co-occurring with La Niña event, the rainfall was significantly increase over the region. This excess rainfall was associated with warm SST anomaly over the eastern tropical Indian Ocean and the Indonesian seas. On the other hand, extreme drought event tends to occur during the 2015 positive IOD simultaneously with the occurrence of the El Niño events Investigation on the SST patterns revealed that cold SST anomalies covered the Indonesian seas during the peak phase of the 2015 positive IOD and El Niño event.

Kota Palembang merupakan daerah yang sebagian besar terbentuk atas lahan rawa yang hampir tergenang air sepanjang tahun. Pada awalnya budaya bermukim masyarakat Palembang dipengaruhi oleh keberadaan sungai, tanah lunak, dan daerah rawa pasang surut membentuk pola dua inti permukiman yang berkembang dari interaksi masyarakat pribumi di bagian utara sungai dan pendatang di bagian selatan sungai. Semakin meningkatnya jumlah penduduk dan semakin intensifnya aktivitas penduduk di suatu tempat berdampak pada makin meningkatnya perubahan penggunaan lahan. Dalam prakteknya, perubahan fungsi lahan ruang terbuka seperti lahan rawa dan tegalan akan berubah menjadi lahan permukiman. Selain membutuhkan lahan, perkembangan permukiman juga membutuhkan sarana prasarana guna memenuhi kebutuhan masyarakat. Penelitian ini bertujuan untuk menganalisis perkembangan permukiman pada Kecamatan Ilir Timur II Kota Palembang pada tahun 1991-2013. Metode penelitian yang dilakukan dalam penelitian ini adalah dengan menggunakan metode Deskriptif. Data yang digunakan meliputi data sekunder. Analisis data spasial digunakan untuk menganalisa perkembangan permukiman di Kecamatan Ilir Timur II. Hasil penelitian menunjukkan bahwa perkembangan permukiman di Kecamatan Ilir Timur II Pada tahun 1991 hingga tahun 2013, pola permukiman di Kecamatan Ilir Timur II menyebar ke segala arah mengisi ruang terbuka untuk dibangun permukiman. Besaran luas permukiman di Kecamatan Ilir Timur II adalah 927,21 Ha pada tahun 1991 dan pada tahun 2013 luas permukiman menjadi 1.311,38 Ha. Berbeda dengan lahan rawa justru mengalami penurunan hingga 81,8% sejak tahun 1991. Saat ini lahan rawa yang tersisa sebesar 20,7 Ha.

Sumatran Admiral Vanessa samani (Hagen, 1895) (Lepidoptera: Nymphalidae) is a butterfly endemic to Sumatra, and can only be found in the Karo Highlands (North Sumatra) and Kerinci Mountain (southwestern Sumatra). In this paper, we report two additional records of V. samani from the Aceh Province in northern Sumatra, and the Jambul Highlands of South Sumatra. These records significantly extend the range of distribution of this rare Sumatran highland species. We also report three plants presumed to be the host plants of V. samani in Sumatra: Boehmeria sp., Smilax sp. (Smilax leucophylla) and Anaphalis sp. (Anaphalis longifolia).
