Abstract

Doyo (Curculigo latifolia) which grows wild in nature is one of the important plants in East Borneo which was many benefit, one of them as as raw material of ulap doyo?s woven fabric. This research was aimed to perform domestication stages by looking at the initial vegetative growth process of doyo plants in one location. Doyo accession was obtained at 15 location points from 6 sub-districts (Tenggarong, Bangun City, Muara Wis, Anggana, Bongan and Jempang) which were then carried out domestically on experimental land in Bukit Biru Village, Tenggarong District. This research used a randomized block design with a single factor were doyo accession (6 accessions). Observation data were analyzed with F test (?=5%) and continued DMRT (Duncan Multiple Range Test) using SAS v. 11.6. The results showed that the highest percentage of live doyo accession in polybags was obtained at Bongan accession (85.16%), while the lowest was obtained at Kota Bangun accession (32.42%). Meanwhile, when planted in the field of research, based on the results of variance showed that the treatment of accession had a significant and very significant effect on the parameters of height increase of plants at 1 and 2 month after planting (WAP), increase in stem diameter,  length  of  leaf  midrib,  leaf  stalk  length,  leaf length,  width leaves,  and the number of new leaves at 1-3 MAP, but not significantly different from the parameters of plant height increase at 3 MAP and number of tillers. The highest leaf length was obtained at Bongan accession, while the highest leaf width ang number of new leaves were obtained at Tenggarong accession. Keywords: Domestication, doyo accession, East Borneo

Abstract

Analysis on sugarcane farming in Bambanglipuro district, Bantul regency, special regency of Yogyakarta has been done to the difference of farming system and to analyze more profitable sugarcane farming between Joint Venture Sugarcane Society (TR.KSU), Partnership Sugarcane Society (TR.KMT), and Independent Sugarcane Society (TR. MAN) farmers.The basic method used is descriptive method and analysis so the analysis on sugarcane farming is worth the effort. Sampling location is at Bambanglipuro district, Bantul Regency with 60 samples taken consisting of 20 Joint Venture Sugarcane Society (TR.KSU) farmers, 20 Partnership Sugarcane Society (TR.KMT) farmers, and 20 Independent Sugarcane Society (TR. MAN) farmers. The result of the research shows that Venture Sugarcane Society (TR.KSU) farmers make profit Rp. 19.180.112/Ha on PC and Rp. 15.531.800/Ha on RC. Partnership Sugarcane Society (TR.KMT) farmers make profit Rp. 18.911.388/Ha on PC and Rp. 15.419.800/Ha on RC, and Independent Sugarcane Society (TR. MAN) farmers make profit Rp 22.983.188/Ha on PC and Rp. 17.985.710/Ha on RC.Value of R/C ratio sugarcane farming per Ha for TR.KSU, TR.KMT, and TR.MAN farmers is more than one. This shows that either PC or RC sugarcane farming is worth the effort.Keywords: Sugarcane farming analysis, society?s sugarcane, partnership, farming suitability

Abstract

Kutai Kartanegara Regency is one of the districts in East Kalimantan, with an area of 27,263 km2. The district is divided into three zones based on the Mahakam river flow, namely the downstream (coastal), middle and upstream zones. In the upstream area, there are many large oil palm plantation companies, which are divided into several sub-districts. However, due to its location which is quite far from the central government, and inadequate road access, some areas in the upstream zone of Kutai Kartanegara are still lagging behind in terms of development from other zones.This study aims to see the extent of the development contribution provided by the existence of oil palm plantations in the upstream zone. The intended development is seen from physical buildings and community development in the area. In addition, this study will look at community perceptions of the existence of oil palm plantations and compare whether there are differences in perceptions in each sub-district of the research location.The results showed that in general palm oil companies contributed to the provision of public facilities in the upstream area of the Mahakam River (Muara Muntai, Muara Kaman, and Kembang Janggut Subdistricts) with diverse outputs in each village. For public perceptions it is still positive both in general and specifically towards changes in the surrounding environment, and there is no significant difference in perceptions between communities in each sub-district. To optimize the role of the company in development, it certainly needs to be supported by implementing technical policies at both the central and regional levels. In addition, monitoring and evaluation from local governments in particular must be improved and sustainable. Keywords : Contributions, Oil Palm Plantation, Development

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

Lai is one of the duriogenealogy who have the potential of domestic and export markets are high enough to accompany the durian. Lai fruit is one of the tropical fruits that are now popular as a source of nutritious food and exotic fruit typical of Kutai Kartanegara. To be able to produce quality fruit crops of quality seeds are required of superior varieties and also professionally managed agribusiness farming.
