Get PDFThe post mining soil has generally known for its high acid, poisonous compound and low macro nutrient concentration. (N, P, K, Ca, and Mg). At this particular soil condition, many of the cultivation plants cannot grow well. Therefore, a research needs to be conducted in order to repair the post mining soil condition by means of increasing the pH and macro nutrient concentration through calcification and litter addition. This research had been done in November until December 2012 at the Agronomy Laboratory, Agriculture Faculty of The Mulawarman University used the Complete Random Design of Factorial (RAL) 2 x 5, with 3 times repetition. The first factor was the Dolomite (D) with 2 levels (d0 = 0 g dolomite/kg soil, and d1 = 6,06 g dolomite/kg soil. The second factor was the litter (T) with 5 levels (t0 = 0 g/kg soil, t1 = acacia litter (Acacia Mangium Will) 100 g/kg soil, t2 = Arachis pintoi litter Krapov. & W.C. Greg 100 g/kg soil, t3= seashore flower (Wedelia trilobata (L.) Hitchc) litter 100 g/kg soil and T4 = sengon litter (Albizzia Falcataria) 100 g/kg soil. This research used the Kailan plant (Brassica oleraceae L. var acephala DC). On the soil which had no dolomite, litter treatment A. Pintoi Krapov.&.K.C.Greg and sengon had positive impact on the pH increase, also for C-organic, N-total, and decreased the C/N value ratio, and Al3+content, followed by the seashore flower litter also influenced positively to the pH, C-organic, N-total increase, and decreased Al3+content. Acacia influenced positively to the C-organic and N-total also, but negatively influenced the C/N ratio and Fe solubility. The dolomite treatment with sengon litter gave additional height to the plants, leaves quantity and wide better than other treatment.

The analysis showed that rice cultivation with organic systems provide different functions and tend to be better than the inorganic system, the togetherness among farmers, soil quality maintenance function, biodiversity, reduction of environmental pollution, and the rural viability
Sustainable Organic Agriculture
No full textPertanian organik adalah teknik budidaya, pemeliharaan, atau pengolahan makanan tanpa menggunakan sebagian besar pestisida dan pupuk sintetis, serta bioengineering, radiasi pengion, dan lumpur limbah.Petani organik berbeda dari petani konvensional karena mereka menolak menggunakan bahan kimia di lahan mereka. Artinya, mereka tidak pernah menggunakan pestisida atau pupuk kimia di ladang mereka. Ini juga menyiratkan bahwa mereka tidak pernah memberi makan hewan mereka pakan non-organik atau memberikan obat-obatan kepada mereka setelah usia tertentu.Di Jakarta, produk petani harus bebas bahan kimia setidaknya selama empat tahun sebelum ia dapat memasarkannya sebagai organik bersertifikat. Namun, itu berbeda dari satu negara bagian ke negara bagian lainnya. Sementara di Indonesia, tanah bebas bahan kimia diperlukan hanya untuk satu tahun, di negara bagian tertentu, diperlukan untuk sepuluh tahun

No full textTINJAUAN 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

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

No full textPENGARUH 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
