Abstract

The climate in Indonesia is a tropical climate with high rainfall, making Indonesia vulnerable to erosion. In addition to high rainfall, vegetation, slope and soil types also affect erosion. This study aims to determine the Important Value of Species (NPJ), the relationship between rainfall and surface runoff and the mass of eroded soil and the level of erosion hazard at different vegetation densities. Important Value The highest types of the three dominating types in plot I were Schima wallichii 115.12%, Macaranga gigantea 69.38% and Cratoxylum sumatranum 44.69%. Whereas in plot II the highest NPJ value of three types dominates, namely Macaranga gigantea 59.13%, Litsea angulata 39.52% and Aquilaria mallacensis 35.37%. The amount of eroded soil mass that occurred in PUE I was 0.13 tons / ha / year and PUE II was 0.19 tons / ha / year. Simple linear analysis of the relationship between rainfall and eroded soil mass at PUE I has a correlation value (r) = 0.79 with the equation Y = -8.34 + 0.39X, whereas in PUE II the correlation value (r) = 0.90 with the equation Y = -12.96 + 0.56X. The danger level of erosion (TBE) in PUE I and PUE II was very mild (erosion rate <15 tons / ha / year, Bahya Erosion I class with soil solum depth> 90 cm).

Abstract

Perladangan gilir balik (shifting cultivation) merupakan cara pertanian tertua yang dijumpai di daerah tropis, di mana petani harus berputar dari satu tempat ke tempat lain dan kembali ke tempat semula setelah beberapa tahun. Bagi suku Dayak yang sebagian besar penduduknya bermata pencaharian sebagai petani, kegiatan perladangan padi adalah sebagai sumber pemenuhan kebutuhan pangan yang paling cocok. Penelitian ini dilakukan untuk Mengidentifikasi jenis padi lokal yang sesuai dengan kondisi lahan. Penelitian ini akan dilaksanakan di Desa Setulang Kabupaten Malinau. Metodologi yang digunakan adalah metode purposif sampling yaitu pengambilan sampel secara sengaja. Analisis data menggunakan deskriptif kualitatif dan dimuat dalam bentuk kurva kalibrasi. Berdasarkan hasil penelitian dapat diketahui bahwa ketiga jenis padi mengalami peningkatan produksi pada tahun ke 10-17 dengan jumlah rata-rata peroduksi berkisar antara 150-250 kg Beras.

Abstract

Estimation of Carbon Stock in Secondary Forest Land Cover, shrubs and thickets in Samarinda. Climate change mitigation efforts have been conducted, among others in the field of land is to be able to maintain the rate of conversion of vegetated land into another use, the role of CO2 absorbent vegetation becomes an important part at this time in order to overcome the global warming. Carbon absorbed by the plants is stored in the form of wooden biomass, so the easiest way to increase carbon stocks is by planting and maintaining trees also maintaining the land in order to keep it vegetated, therefore it is necessary to have carried out research aimed suspect carbon reserves on the type of cover land either shrubs, thickets and secondary forests, in Samarinda city. The study was conducted by the plot and the data retrieval with destructive and non-destructive and the analysis calculations using allometric. By the results of the study, it was found that the estimation amount of reserves of biomass on land cover in the form of Secondary Forest is the largest that is 203.826 tons/hectare, then the biomass in vegetation undergrowth of 74.180 tons/hectare and the third on vegetation shrub that is equal to 56.306 tons/hectare, On the third closure of the land and from the various components of the biomass vegetation, trees with a diameter 2cm up  have the largest biomass content as carbon sinks through the process of photosynthesis is 27.026 tons/hectare, 55.308 tons/ hectare and 137.473 tons/hectare, while rooting ranks second. Same as the content of the biomass, carbon stock estimation is the largest in land cover in the form of secondary forests, thickets and shrubs, are respectively 95.798 tons/hectare, 42.667 tons/hectare and 26.464 tons/hectare. Carbon content estimation on top (Above Ground Carbon) each respectively based on the order of the land cover is 69.93 tonnes/ hectare, 31.14 tons/hectare and 19.32 tons/hectare.

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.
