Pengujian beberapa varietas tebu telah dilaksanakan di Desa Sungai Asam Kecamatan Kayu Aro Barat Kabupaten Kerinci Provinsi Jambi. Tujuan kegiatan adalah mengamati pertumbuhan tanaman tebu yang tumbuh baik sebagai penghasil gula merah. Kegiatan pengkajian menggunakan Rancangan Acak Kelompok, dengan perlakuan empat varietas tebu unggul dan satu tebu lokal sebagai pembanding. Masing-masing varietas ditanam berupa demplot dengan ulangan 4x. Adapun varietas tebu unggul yang diuji adalah : V1 = PS 951 ; V2 = Bululawang (BL), V3 = POJ 3016 ; V4 = PS 864 dan V5 = Tebu lokal Kerinci. Hasil pengujian memperlihatkan bahwa ada 3 varietas tebu yang tumbuh baik yaitu PS 951, BL dan tebu lokal. Varietas PS 951 lebih baik pertumbuhan nya dibandingkan varietas BL, POJ 30161, PS 864 dan varietas lokal. Pertumbuhan ketiga varietas ini tidak berbeda nyata, namun varietas lokal Kerinci mempunyai nilai brix atau rendemen yang tinggi karena sudah beradaptasi dengan daerah dataran tinggi, sehingga mempunyai prospek yang baik untuk dikembangkan di Kabupaten Kerinci. Tanaman tebu lokal Kerinci, telah dilepas menjadi tebu lokal unggul nasional pada tahun 2016 kerjasama BPTP, Balittas dan Pemda Kab. Kerinci dengan nama “POJ 2878 Agribun Kerinci. Dari hasil analisis ekonomi tanaman tebu “POJ 2878 Agribun Kerinci, dengan pengelolaan cara petani, produksi gula merah dapat mencapai 8.320 kg/ha/tahun, jika harga gula merah Rp 7.500,-/kg dapat menghasilkan sekitar Rp 3.813.333,- (tiga juta delapan ratus tiga belas ribu tiga ratus tiga puluh tiga rupiah)/ha/bln. Jika pengolahan nira tebu diolah menjadi produk gula semut, dapat menghasilkan gula semut sekitar 5.120 kg/ha. Dengan harga gula semut Rp 15.000,-/kg pendapatan petani setara dengan Rp 5.013.333,- (lima juta tiga belas ribu tiga ratus tiga puluh tiga rupiah) per hektar/bulan. dimana petani akan memperoleh nilai tambah sebesar Rp 1.200.00,- (satu juta dua ratus ribu rupiah) lebih tinggi. Dengan inovasi teknologi sesuai dengan rekomendasi teknologi, produksi tebu POJ 2878 Agribun Kerinci masih berpotensi untuk ditingkatkan.
The research objective is to optimize the use of lowland swamps to increase land productivity, crop productivity and income of farmers using the technology innovation management. Lowland PENDAHULUANLahan rawa merupakan agroekologi potensial yang telah banyak dimanfaatkan untuk pengembangan pertanian. Luas lahan rawa di Indonesia diperkirakan mencapai 33,4 juta hektar, yang terdiri dari 20,12 juta hektar lahan pasang surut dan 13,28 juta hektar lahan lebak (Nugroho et al., 1992). Lahan rawa terdiri dari berbagai tipologi dan tipe luapan dengan karakteristik yang berbeda dan dengan kendala yang berbeda pula, sehingga penanganannya harus dilakukan secara serius dan hati-hati. Salah pengelolaan akan mengakibatkan rusaknya lahan dan memerlukan biaya mahal dan waktu lama untuk memulihkannya kembali (Widjaja-Adhi et al., 1992; Abdurahman et al., 1999).Provinsi Jambi dengan luas wilayah 5,1 juta hektar terdiri dari lahan kering seluas 2,65 juta ha dan lahan pertanian tanaman pangan seluas 352.410 ha. Luas lahan rawa diperkirakan mencapai 684.000 ha, untuk usaha pertanian kurang lebih 246.481 ha terdiri dari lahan pasang surut 206.832 ha dan lahan rawa lebak 40.521 ha (Busyra et al., 2000). Lahan rawa lebak belum diusahakan secara maksimal untuk usaha pertanian, dengan menerapkan teknologi penataan lahan serta pengolahan lahan dan komoditas pertanian secara terpadu, lahan rawa lebak dapat dijadikan sebagai salah satu andalan sumber pertumbuhan agribisnis dan ketahanan pangan nasional (Ar-Riza dan Jumberi, 2008). Produksi tanaman padi di lahan lebak masih relatif rendah berkisar 3-3,5 t/ha, sedangkan peluang peningkatan produksi tersebut cukup besar mengingat areal cukup luas dan teknologinya tersedia. Rendahnya produksi tanaman padi disebabkan budidaya pertanian yang diterapkan oleh petani umumnya belum sesuai anjuran. Menurut , permasalahan
Growing sugarcane in a double row planting system is one way to increase the productivity and sugar cane yield. Intercropping within sugarcane crops can increase the growth and productivity of sugarcane. This study aims to increase the productivity of sugarcane by adding value to potato cropping. The study used Randomized Block Design, where the treatments ae as follows: sugar cane as a planting system (A), double castor planting system (PtoP 210/50 cm) with cuttings of sugarcane stem + potato’s (B); double distance planting system (PtoP 185/50 cm) with cuttings stem sugarcane + potato’s (C); double distance planting system (PtoP 160/50 cm) with cuttings sugarcane stem + potato’s (D); double distance wedge system (PtoP 135/50 cm) with cuttings of sugarcane stem + potato. The planting system (PtoP 110/50 cm) with cuttings of sugarcane stem without planting potato was considered as control (E). All planting systems were repeated four times. The results of the study showed that the agronomic growth of sugar cane crops in some planting systems is not different, but in C and D planting systems, the number of leaves and the number of tillers were higher compared to others. Potatoes crop production in planting systems C reached 11,880 tons ha-1, which is higher than the production of planting systems A (8,640 tons ha-1.) and planting systems B (8,400 tons ha-1). After combining the determining factors of sugar cane production, the C planting systems is recommended for development of sugarcane crops because is better than other planting systems. The population of sugar cane plants in the C planting systems reached 18,000 clumps of plants per hectare
This study examined the issue of identity politics and the threat of pluralism in Bukittinggi, West Sumatra. The people of Bukittinggi, West Sumatra consisting of various ethnicities, tribes, races and cultures have been able to live with a spirit of pluralism and tolerance. Lately, the spirit of pluralism that has been run by the people of Bukittinggi, West Sumatra began to erode along with the strengthening of identity politics. The prominence of tribal, religious, racial and cultural identities becomes a serious problem in a plural society, because, the spirit of highlighting tribal, racial, cultural and religious identities excessively leads to claims of truth and the assumption that their tribes, races, religions and cultures are superior to cultures, races, tribes and religions outside their groups. In collecting data, this study uses qualitative methods. The research stages carried out are literature studies, observations, documentation, and interviews. The research will be guided by social theories such as identity politics and pluralism. The finding of this research is the strengthening of identity politics in Bukittinggi related to religious issues. Politically, religions outside of Islam are limited. This religious identity is further strengthened by the emergence of many religious groups in the midst of the people of Bukittinggi, West Sumatra. like Islamic organizations that massively bergeriliya in carrying out its mission to Islamize the entire community of west Sumatra. The movements carried out by islamic organizations seem to be strengthened by ethnicity (tribal), in the form of customs of the people of Bukittinggi, West Sumatra which is famous for its integration of customs and religions. Indirectly religion outside the religion of Islam its existence is limited in Bukittinggi, West Sumatra.
