Abstract

Pertambangan batubara di Kabupaten Kutai Kartanegara  merupakan kegiatan pemanfaatan sumberdaya alam yang tidak dapat diperbaharui (unrenewable resources). Penambangan batubara secara terbuka memberikan dampak negatif terhadap penurunan kualitas  lahan, seperti perubahan bentang lahan (alam), rusaknya pipa-pipa kapiler dan permeabilitas tanah, kurangnya  daya  penyimpanan  air, dan terjadinya penurunan kualitas tanah sehingga reklamasi lahan pasca tambang yang benar menjadi sangat strategis untuk pemanfaatan lahan selanjutnya agar menjadi produktif.Tujuan kajian ini adalah untuk  meningkatkan kualitas lahan  pasca tambang guna untuk dimanfaatkan menjadi lahan produktif dengan berbagai kegiatan reklamasi. Kajian dilaksanakan pada bulan Mei sampai Agustus 2014 dalam wilayah Kabupaten Kutai Kartanegara.Metode analisis  yang digunakan adalah analisis deskriptif kualitatif. Hasil kajian menunjukkan bahwa reklamasi lahan pasca tambang harus dilakukan sejak tahap  prakonstruksi, konstruksi,   operasi sampai pasca operasi tambang. Pada tahap prakonstruksi,  upaya   reklamasi melalui pembebasan lahan dengan sistem sewa lahan  kepada   pemilik lahan lebih cepat terjadi peningkatkan kualitas lahan dibanding sistem pembebasan lahan ganti putus karena perusahaan dituntut memperbaiki kondisi lahan sehingga menjadi produktif. Pada tahap   konstruksi, upaya reklamasi dengan pembukaan lahan tanpa pembakaran (zero burning) dan pengolahan biomassa hasil   pembersihan   lahan menjadi pupuk organic mempercepat perbaikan kualitas lahan.  Kemudian pada tahap operasi, tanah pucuk (top soil) dan tanah   penutup (sub soil) yang dikembalikan pada posisi semula (sebelum penambangan) dan dilanjutkan dengan kegiatan revegetasi dengan pengayaan tanah   melalui   penambahan pupuk  organik   dan  pertanian  terpadu melalui integrasi ternak dengan tanaman produktif  dan  bernilai   ekonomis sangat mendukung peningkatan kualitas lahan. Selanjutnya,    pada tahap pasca operasi yang dilakukan kegiatan reklamasi lanjutan minimal tiga tahun pasca tamban dapat  memperbaiki kondisi tanaman   sehingga  lahan  menjadi produktif.Keyword : Reklamasi, lahan pasca tambang, lahan produktif

Abstract

The aim of the research was energy analysis (input-output) cucumber in cultivation under sprinkler irrigation system. Data were collected using interview method from cucumber farmer that cultivation cucumber in field 15 x 9 m2 in Bengalon, Kutai Timur. The results indicated that  total energy input and total energy output was found 35 204 MJ/ha and 69 926 MJ/ha, respectively. The energy indices covering energy rasio (energy use efficiency), energy specific,  energy productivity and net energy were 1,99,  0,40 MJ/kg, 2,48 kg/MJ and 34 722 MJ/ha, respectively. The cucumber cultivativation under sprinkler irrigation system, 38,21 % of total energy input was classified direct energy and 61,79 % was indirect energy. Results futher indicated that 90,18 % of total energy input was in non-renewable energy form, and only 9,82 % was in renewable form. The main non-renewable inputs were fuel and chemical fertilizers 34,53 % and 22, 69 %, respectively. Therefore, irrigation efficiency should be improved and reductions of chemical fertilizers would be suggested to reduce non-renewable energy input in cucumber cultivativation under sprinkler irrigation system. Keywords: Cucumber cultivation, energy rasio, input energy, non-renewable energy, sprinkler irrigation system

Abstract

This study aims to determine the effect of ostindo fertilizer and leaf defoliation on corn  yield (Zea masy L.). The study began in October 2018 until January 2019, located in the village of Bendang Raya, Tenggarong District, Kutai Kartanegara Regency. This study was arranged in a Randomized Complate Block Design (RCBD) with a 4 x 3 factorial analysis with replications three times. The first factor for giving ostindo fertilizer (p) consisted of 3 levels, namely, p0 (untreated control), p1 (45 g plot-1), and p2 (90 g plot-1) and the second factor leaf defoliation (d) that is, d0 (control without treatment), d1 (70 days), d2 (77 days), and d3 (84 days).The results showed that ostindo fertilizer removal had no significant effect on the parameters of observation of plant height, leaf defoliation weight, ear weight without weight per plant, weight of crop seeds, including the weight of 100 seeds. With the highest yield average dry weight per hectare (t ha-1), that is in treatment p1 (45 g plot-1) which is 4.65 t ha-1 whereas for the lowest yield dry weight shelled per hectare (t ha-1) is treatment p0 (without treatment) with an average yield of 4.47 t ha-1.Then the treatment of leaf defoliation did not significantly affect the parameters of observation of  ear weight without plant per plant, weight of planting seeds, weight of 100 seeds and dry weight per hectare (t ha-1) ie, the highest yield was obtained from the average shelled dry weight per hectare (t ha-1), that is in treatment d1 (70 days after planting) which is 4.80 t ha-1 whereas for the lowest yield dry weight per hectare  (t ha-1) is treatment d0 (without treatment) with an average average 4.40 t ha1.The interaction between ostindo fertilizer and leaf defoliation had no significant effect on all parameters observed, the highest average yield of dry weight per hectare (t ha-1) in treatment p1d1 (45 g plot-1 and 70 days after planting) with an average yield 4.87 t ha-1. The lowest yield was dry shelled weight per hectare (t ha-1) in p2d3 treatment (90 g plot-1 and 83 days after planting) with an average yield of 4.23 t ha-1. Key word :  Ostindo fertilizer, leaf defolition, corn yield

Abstract

This study aims to determine the effect of Kayabio biofertilizer and fertilization methods on the growth and yield of corn (Zea Mays L.). The study began in September to December 2018, located on the farm land of Marangan Hamlet, Loh Sumber Village, Loa Kulu District, Kutai Kartanegara Regency, East Borneo Province.The study was arranged in Factorial Randomized Complete Block Design (RCBD) consisting of 2 factors and repeated 3 times. The first factor was the administration of Kayabio (p) biological fertilizer which consisted of 4 levels, namely p0 (without fertilizer), p1 (18 g plot-1), p2 (36 g plot-1), p3 (54 g plot-1). And the second factor is How to Fertilize (c) which consists of 3 levels, namely c1 (way of Portugal), c2 (how to run) and c3 (spread).The results showed that Kayabio biofertilizer had no significant effect on all observed parameters. The highest yield on average yield of dry seed shelled t ha-1 is on p3 with an average yield of 3.78 t ha-1 and the lowest yield of dry seed shell weight t ha-1 is at p0 with an average yield of 4,19 t ha-1.The results showed that the fertilization method had no significant effect on all observational parameters. The highest yields of average dry seed seed weight t ha-1 are in c1 with an average yield of 4.20 t ha-1 and the lowest yield of dry seed shell weight t ha-1 is in c3 with an average yield of 3.80 t ha-1.The results of the interaction between Kayabio biofertilizer and fertilization methods had no significant effect on all observational parameters. The highest yields of average dry seeds of shelled beans t ha-1 were at p3c1 with yields of 4.61 t ha-1 and the lowest yields of yields of dry seeds of shelled beans t ha-1 were in treatment p1c3 with a yield of 3.59 t ha-1. Key words : Kayabio biofertilizer, fertilization method and corn production
