PENGARUH  PERUBAHAN  IKLIM TERHADAP POPULASI PESUT(Orcaela brevirostris) Di KALIMANTAN TIMUREffect  of Climate Change on the Fresh-Water Dolphin (Pesut) Population(Orcaela brevirostris) In East KalimantanJohansyahFakultas Pertanian, Jurusan Kehutanan, Universitas PalangkarayaPalangkaraya ABSTRACTGlobal climate change is the dynamics agent of environmental degradation, such as habitat of Mahakam Dolphin (Pesut). The degradation is very dangerous for the continuity of Pesut population life and Pesut is highly sensitive toward changes of such factor. Based on several studies conducted, today is found that population of Pesut until the year 2010 is estimated only 50 individuals, while according to Rasi (2011), it ranged 70-80 individuals. The more reduced number of Pesut population from year to year may fear, thus the extinction of this wildlife species could occurred. Some factor influencing the declining of Pesut population are the destruction of forests, changes of Pesut distribution, decreased water oxygen levels and chemical pollution of rivers.Key words : Pesut, Mahakam, Populasi, Perubahan iklim.

KERUSAKAN TIPE EKOSISTEM KARST DAN PENGARUHNYA TERHADAP PERUBAHAN IKLIM (SUATU PENDEKATAN TEORI) The Damage of Karst Ecosystem and Its Impact on The Climate Change (a theoretical approach)Benteng. H SihombingFakultas Kehutanan, Universitas MulawarmanSamarinda ABSTRACTKarst ecosystem poses high economic potency however its attention was lack due to to date only pay attentions merely on mineral resource potency, and its conservation measure only focus to some extent on cave. Mean while, karst area owns wider protective function, such as water conservation, state revenue from tourism, mining, bird nest, even it closely relates to the national security issue and state intelligence. Pay an attention on karst ecosystem that covers biotic potency and mineral energy exploration is tought to be far from seriousness meanwhile its tension on this ecosystem tends to be larger, even already comes to the stage of ecology endanger. In relation to the global temperature rise that leads to the climate change, natural karst ecosystem seems pay a big role in reducing carbondioxide through karstifikasi process. Therefore, the karst ecosystem conservation is an urgent agenda.Key words : Karst, Ecosystem, Climate change.

Statistically, this study revealed that two parameters (rainfall and vegetation) has contribute to the discharge flow and discharge suspended load sediment  and respectively it represented by its correlation coefficient which are 0.89-0.97 and 0.86-0.94. The values tend to closed to 1 and it indicate a positive correlation between parameters and discharge flow, as well as discharge suspended load sediment. Discharge flow and discharge suspended load sediment also related each other. The increases of discharge flow will lead to the increases of discharge suspended load sediment. Discharge suspended load sediment will increase whenever a lot of sediment from erosion flow to the river body. Discharge suspended load sediment increase in the river number 2, 4 and 5 because landuse changing occurred in the upper of the rivers outside of the forest. Potential sediment volume in a year at the each sampling points are 895.38 ton at River 1,464.23 ton at river 2,889.04 ton at river 3,336.76 ton at river 4,173.68 ton at river 5 and 335.56 ton at the lake.Key words : rainfall intensity, discharge flow, suspended load sediment.

TINJAUAN KEADAAN PADI SEBAGAI TANAMAN PANGAN UTAMA DI INDONESIA DAN DI KALIMANTAN TIMURState of The Art of Paddy as Staple Food in Indonesia and Situation in East KalimantanAbdul FatahSekolah Tinggi Ilmu Pertanian (STIPER) Kutai TimurSamarinda ABSTRAKSwasembada beras pernah dicapai oleh Indonesia pada tahun 1984, namun sejak tahun tersebut produksi padi nasional tidak mampu lagi mencukupi kebutuhan penduduk akibat tidak seimbangnya jumlah produksi padi dengan jumlah penduduk yang terus bertambah. Secara nasional,  produksi padi selama kurun waktu 40 tahun telah meningkat empat kali lipat, sejak dari delapan juta ton hingga 32 juta ton  melalui revolusi hijau. Kencederungan produksi padi juga meningkat belakangan ini, pada tahun 2008 kembali swasembada beras dicapai. Terlebih lagi, Indonesia yang selama ini dikenal sebagai inportir terbesar, telah didekati oleh sejumlah Negara yang berminat untuk menginpor beras dari Indonesia. Situasi di Kalimantan Timur sedikit berbeda dimana swasembada  beras selama ini belum pernah dicapai. Target pencapaian yang seringkali dicanangkan masih belum mampu diwujudkan. Dengan melihat berbagai kendala di lapangan, ada beberapa aspek yang perlu dipertimbangkan manakala swasembada ingin segera dicapai, diantaranya adalah memaksimalkan fungsi irigasi drainase serta penanganan pasca panen; memaksimalkan percepatan ekstensifikasi lahan sawah baru, dan meminimalkan alih fungsi lahan sawah produktif dari penggunaan lahan lainnya.Key words : Swasembada beras, Tanaman pangan, Kalimantan Timur.
