Abstract

The experiment was conducted at the Community Forestry area in the Giri Agung Village of Sebulu Sub District, Kutai Regency.  Planting implementation was in 2006.  Research carried out for about 2 effective months (from May to June 2012).  The object was Gaharu crop of 6 years old in the Giri Agung Village with the total samples 30 crops planted at the top of hill, and 30 crops planted at the slope.  The data was analysed with SPSS 12 t-test to determine the differences in growth at the top and on the slopes at the significant level 95%. The results showed that the Gaharu crop growth at top and at slope hill were not significantly different on both crop diameter and height growth by the t test.  The results of the statistical test using t-test showed that t-count is less than t-table which means there is no significant difference in the average of crop height at the top and slope.  There were several limiting factors for optimum growth of Gaharu.  They were soil factors, especially pH and limitation availability of some macro and micro nutrients, because almost all the nutrients required by the Gaharu is generally lacking.  Therefore, it needed an improvement or increase in the availability of nutrients by fertilizing with both organic and inorganic fertilizers that are required by the Gaharu.

Abstract

The research objectives were: (1) to determine the effect SP-36  fertilizer and cow manure as well as their interaction on the growth and yield of barley; and (2) to obtain appropriate dosages of SP-36 fertilizers and cow manure to obtain better yield of Barley.The research was conducted from February to June 2015 in Sekolaq Darat village, sub district of Sekolaq Darat, West Kutai Regency.It applied 4 x 3 factorial experiment in a Randomized Block Design (RBD) with three replications.  The first factor was the dose of SP 36 fertilizer (P) which comprises two levels, namely: no SP-36fertilizer application or control (po), 60 gr/crop (p1) and 120 gr/crop(p2). The second factor was the dose of cow manure (T) consisting of three levels, namely: no cow manure application (to), 500 gr/crop (t1), 750 gr/crop (t2) and 1000 gr/crop(t3). Data analysis used analysis of variance (Anova) and advanced test by using with the Least Significant Difference (LSD) at level of 5%.Result of the reseach showed that: SP-36 fertilizer affected significantly to highly significant on the plant height at the age of 25, 50, 75, and 100 days after planting,number of tiller/cluster and production.  The highest yield was attained at the treatment 120 gr/cropSP- 36 fertilizer (p2) namely 0,29. ,meanwhile the lowest one was at the no SP- 36 fertilizer application at SP-36 (po), namely  0.27Effect of cow manure was highly significant on the plant height at 25, 50, 75, and 100 days after planting and number of tiller/cluster.  The highest production was attained at the treatment of 1000 gr/crop(t3) namely  0,28meanwhile the lowest one was at the treatment of no manure application(to),namely 0,30.Effect of interaction between SP-36fertilizer and cow manure was significantly different on the plant height at 50, 75 and 100 days after planting, number of tiller/cluster, but it did not affect significantly on the plant height at 25 days after planting and crop production.

The experiment was conducted from March to June 2010 at Bukit Pinang Village, Samarinda. The research emploved the Randomized Completely Block Design (RCBD) wich consisted of six insecticide treatments, i.e. : Po = Control (ni Vitura and Deltametrin application), P1 = 0,75 g Vitura L -1 water, P2  = 1,5 g Vitura L-1 water, P3  = 5 g Deltametrin L-1 (no Vitura application), P4  = 0,75 g Vitura + 5 mg Deltametrin L-1 water and P5  =  1,5 g Vitura + 5 g Deltametrin L-1 water. All treatment were repeated 5 times. The result experiment showed that the treatment affected significantly to attack intensity of pest and yield of bean. The lowest intensity of pest attack and the highst bean yield was obtained on combination of Vitura and Deltametrin at concentration 1,5 g + 5 mg L-1 water.Key words : Bean, Pest, Vitura (S/NPV, Deltametrin.

Abstract

Tujuan penelitian untuk mengetahui pengaruh pemberian pupuk SP-36 dan pupuk kotoran kambing terhadap karakteristik agronomis tanaman aren genjah yang terbaik dan hasil tanaman kakao sebagai tanaman sela serta intensitas serangan hama dan penyakit pada penanaman sistem jalur. Penelitian dilaksanakan di lahan di Desa Badak Mekar Kecamatan Muara Badak Kabupaten Kutai Kartanegara, Kalimantan Timur. Metode penelitian menggunakan Rancangan Acak Kelompok (RAK) dan diulang sebanyak 4 kali. Percobaan faktorial terdiri dari 2 faktor, sebagai faktor pertama adalah  pupuk SP-36 (p) terdiri dari 3 taraf: p0 = 0 kg tanaman-1 (kontrol); p1 = 0.4 kg tanaman-1; p2 = 0.8 kg tanaman-1. Faktor kedua adalah pupuk kotoran kambing (k) terdiri dari 3 taraf: k0 = 0 kg tanaman-1 (kontrol); k1 = 7.5 kg tanaman-1; k2 = 15 kg tanaman-1. Variabel yang diamati meliputi: 1) tanaman aren genjah: a. batang: lilitan batang, b. daun: panjang tangkai daun, jumlah daun (pelepah), panjang racis daun, jumlah anak daun, panjang anak daun, lebar anak daun, panjang tangkai pelepah, tebal tangkai pelepah, 2) tanaman kakao: hasil buah kakao dan intensitas serangan hama dan penyakit 3) analisis sifat kimia tanah : pH, C-organik, N, P, K, Kation basa, Kation asam, KTK dan Kejenuhan basa, 4) analisis mikroorganisme tanah. Data dianalisis dengan sidik ragam dan jika terdapat perbedaan nyata maka dilanjutkan dengan Uji Beda Nyata Terkecil (BNT) pada taraf 5 %. Sedangkan analisis karakteristik kimia tanah menggunakan kriteria penilaian status kimia tanah dan status kesuburan tanah dari Pusat Penelitian Tanah.Hasil penelitian pemberian pupuk SP-36 menunjukkan berbeda sangat nyata  terhadap karakteristik batang tanaman aren genjah yaitu lilitan batang umur 6 bulan setelah perlakuan (bsp) dan 9 bsp serta berbeda nyata terhadap karakteristik daun tanaman aren genjah yaitu panjang tangkai daun umur 3 bsp, 6 bsp dan 9 bsp, panjang racis daun umur 9 bsp dan jumlah pelepah umur 9 bsp. Pemberian pupuk SP-36 dengan dosis 0.8 kg tanaman-1 (p2) memberikan pertumbuhan tanaman aren genjah yang terbaik.Perlakuan pupuk kotoran kambing serta interaksi antara pupuk SP-36 dan pupuk kotoran kambing berbeda tidak nyata terhadap tanaman aren genjah pada semua variabel pengamatan dan hasil buah  kakao.Hasil pengamatan rata-rata intensitas serangan hama pada buah kakao adalah 58.94% dan termasuk kedalam kategori rusak sedang. Sedangkan rata-rata intensitas serangan penyakit pada buah kakao adalah 33.34% dan termasuk kedalam kategori rusak ringan.Hasil analisis sifat kimia tanah menunjukkan pH tanah 5.49 (masam), kandungan C organik 3.51% (sedang), C/N rasio 17.13 (tinggi), N 0.20 (rendah), P 4.00 (rendah) dan K 100.68 (tinggi).Hasil analisis mikroorganisme tanah menunjukkan lahan penelitian teridentifikasi bakteri terdiri dari 2 Famili yaitu Azotobacteraceae dan Bacillus, jamur dengan genus Trichoderma serta Nematoda terdiri dari 3 genus yaitu Rotylenchus, Rabditis dan Dorylaimus. Mikroorganisme tanah tersebut berperan sebagai biofertilizer, biofungisida dan dekomposer.

Abstract

Penilaian stok karbon tidak hanya pada vegetasi hutan, tetapi juga pada tanah termasuk tanah pertanian atau kebun, karena secara global stok SOC (soil organic carbon) ternyata merupakan teresterial terbesar cadangan karbon organik. Tujuan penelitian ini untuk mengetahui stok karbon tanah organik di kebun lada, kebun campuran, kebun karet, kebun jati dan lahan semak. Metode pengambilan sampel tanah ditentukan secara purposive sampling, kemudian untuk analisis stok karbon tanah organik berdasarkan kerapatan lindak, C-organik dan kedalaman tanah mengacu pada penilaian oleh Badan Standarisasi Nasional.Total SOC di berbagai  tempat tergantung dari karakteristik tanah, curah hujan, manajemen pengolahan tanah, topografi, organisme tanah, dan faktor lingkungan lainnya. Berdasarkan penilaian SOC di kebun campuran dan kebun karet lebih tinggi, yaitu 160 dan 121 ton/ha. Kedua lahan tersebut memiliki kelerengan datar, sehingga potensi kehilangan bahan organik di tanah permukaan akibat erosi tergolong rendah. Sedangkan di kebun lada, jati dan semak masing-masing 60. 25 dan 24 ton/ha. Penilaian total SOC berdasarkan kandungan C-organik, kerapatan lindak (Bulk Density) dan kedalaman tanah tertentu pada tiap satuan unit lahan dianggap cukup signifikan, sehingga penelitian seperti ini lebih banyak lagi dilakukan dalam rangka menguatkan informasi untuk estimasi total SOC untuk daerah yang lebih luas atau secara global.
