Tantangan Pengembangan Padi Dikabupaten Kepulauan Mentawai

This study aims to identify the problems and develop rice agribusiness in Mentawai Islands from upstream to downstream and formulate appropriate policy recommendations to be implemented. The research location determined by purposive namely in the village Makalo and Malakopa District of South Pagai, Sikakap subdistrict Taikako Village, Village Saumanganya District of North Pagai, Bosua Village and Village Beriulou District of South Sipora, Village Rogdog and Madobag District of South Siberut. Respondents in this study were 30 farmers. Respondents farmers selected by simple random sampling method. The results showed that the majority of rice paddies new openings in six districts consist of peatlands with a depth varying from 0.4- > 2.0 meter, fields new openings that have been implemented in the Mentawai Islands in general can not be expected to result in maximum productivity due to problems of land suitability diverse. Farmers also do not take action appropriate technical culture starting from land preparation, seed selection, weeding, fertilizing and water management. Behaviorally agriculture, farmers in Mentawai Islands is not a society that blends with the culture of rice fields, it is because basically their agricultural base is dry land agriculture with farming patterns. This will certainly give a great challenge and not easy for the cultivation of rice in the Mentawai Islands

We study here how within-individual plasticity in Moricandia arvensis flowers modifies its pollination niche. During spring, this plant produces large, cross-shaped, UV-reflecting lilac flowers attracting mostly long-tongued large bees. However, unlike most co-occurring species, M. arvensis keeps flowering during the hot, dry summer due to its plasticity in key vegetative traits. Changes in temperature and photoperiod in summer trigger changes in gene expression and the production of small, rounded, UV-absorbing white flowers that attract a different assemblage of generalist pollinators. This shift in pollination niche potentially allows successful reproduction in harsh conditions, facilitating M. arvensis to face anthropogenic perturbations and climate change. Floral phenotypes impact interactions between plants and pollinators. Here, the authors show that Moricandia arvensis displays discrete seasonal plasticity in floral phenotype, with large, lilac flowers attracting long-tongued bees in spring and small, rounded, white flowers attracting generalist pollinators in summer.Spanish Ministry of Science, Innovation and Universities (EU FEDER funds) CGL2015-71634-P CGL2015-63827-P CGL2017-86626-C2-1-P CGL2017-86626-C2-2-P UNGR15-CE-3315Junta de Andalucia P18-FR-3641Xunta de GaliciaBBVA Foundation PR17_ECO_0021Spanish Ministry of Economy and Competitiveness RYC-2012-12277Consejeria de Economia, Conocimiento, Empresas y Universidad SOMM17/6109/UGREuropean Union (EU) SOMM17/6109/UG

POKOK-POKOK PIKIRAN DOSEN FAKULTAS PERTANIAN UNIVERSITAS ANDALAS PERSPEKTIF PERTANIAN TROPIKA BASAH:POTENSI DAN TANTANGANNYA DALAM RANGKA PERTANIAN BERKELANJUTAN

Buku ini membahas keragaman hasil penelitian yang telah dilakukan dan juga merupakan hasil pemikiran yang mendalam tentang pertanian di Sumatera Barat khususnya dan Indonesia umumnya bagi kemajuan bangsa Indonesia yang dilakukan oleh Dosen Fakultas Pertanian Universitas Andalas dari berbagai aspek terkait pertanian berkelanjutan khususnya pada aspek pertanian tropika basah, teknologi dasar untuk pertanian tropika basah, potensi diversifikasi pangan, dan aplikasi terapan dalam budi daya tanaman, serta aspek sosial ekonomi dan modal sosial. Masalah utama yang harus dihadapi di dalam pemanfaatan lahan pada daerah tropika basah adalah keadaan sosial ekonomi petani atau masyarakat yang menggunakan lahan sebagai tempat usahanya. Pendapatan keluarga yang rendah serta kemiskinan di banyak tempat berkorelasi positif dengan usaha tani. Rendahnya produktivitas lahan, selain disebabkan oleh tingkat kesuburan tanah yang rendah, juga disebabkan oleh rendahnya intensitas indeks pertanaman karena kebutuhan air tidak tersedia sepanjang tahun. Untuk meningkatkan produktivitas lahan, selain pengapuran dan pemupukan dapat dilakukan dengan optimalisasi pola tanam, penggunaan varietas unggul dan unggul lokal, pemanfaatan mikroorganisme indigenus, meningkatkan intensitas indeks pertanaman, mengurangi aliran permukaan/erosi, dan evaporasi tanah oleh adanya penutupan tanaman dan sisa hasil panen yang dapat berfungsi sebagai mulsa dan menambah bahan organik tanah. Pengelolaan sumber daya lahan harus dipandang sangat penting berdasarkan pertimbangan bahwa proses pembangunan yang sedang dan akan dilakukan di Indonesia masih tergantung pada cara memanfaatkan potensi sumber daya lahannya

Recent advances in ankylosing spondylitis: understanding the disease and management

The term spondyloarthritis refers to a group of immune-mediated diseases characterised by inflammation of the axial skeleton, peripheral joints, and entheses. Ankylosing spondylitis (AS) is the most common and characteristic of these entities and even though it was first described over two centuries ago, the understanding of the underlying disease mechanism remains incomplete. It is known that around 40% of patients with AS have subclinical bowel inflammation, suggesting that the origin of the disease could be in the gut. Also, more genes and new molecules have demonstrated a role in the pathogenesis of AS. In this review, we analyse the latest therapies for spondyloarthritis and the most relevant discoveries over the last three years, together with their implications for different aspects of the disease

The Use of Transmission Line Modelling to Test the Effectiveness of I-kaz as Autonomous Selection of Intrinsic Mode Function

Pressure transient signal occurred due to sudden changes in fluid propagation filled in pipelines system, which is caused by rapid pressure and flow fluctuation in a system, such as closing and opening valve rapidly. The application of Hilbert-Huang Transform (HHT) as the method to analyse the pressure transient signal utilised in this research. However, this method has the difficulty in selecting the suitable IMF for the further post-processing, which is Hilbert Transform (HT). This paper proposed the implementation of Integrated Kurtosis-based Algorithm for z-filter Technique (I-kaz) to kurtosis ratio (I-kaz-Kurtosis) for that allows automatic selection of intrinsic mode function (IMF) that's should be used. This work demonstrated the synthetic pressure transient signal generates using transmission line modelling (TLM) in order to test the effectiveness of I-kaz as the autonomous selection of intrinsic mode function (IMF). A straight fluid network was designed using TLM fixing with higher resistance at some point act as a leak and connecting to the pipe feature (junction, pipefitting or blockage). The analysis results using I-kaz-kurtosis ratio revealed that the method can be utilised as an automatic selection of intrinsic mode function (IMF) although the noise level ratio of the signal is lower. I-kaz-kurtosis ratio is recommended and advised to be implemented as automatic selection of intrinsic mode function (IMF) through HHT analysis

The Role of Ficus Crassiramea (Miq.) Miq. for Hornbill Conservation in Borneo Fragmented Tropical Rainforest

Fig plants (Ficus spp.) are considered as a key candidate to wildlife conservation in tropical rainforest for its potency on their microhabitat and food supply throughout the years. In this research, we focused only on the Ficus crassiramea (Miq.) Miq. To shows its role for hornbill conservation, we observed the different species of hornbill which visiting the trees and also we observed time, duration, frequency and activity of visits of the hornbill. For the purpose, four trees of F. crassiramea had been observed continuously for 6 d from 06.00 am to 05.00 pm in two fragmented tropical rainforest located in Penajam Paser Utara Regency, Borneo, Indonesia. The result showed, there were three species of hornbill which are visiting the plants in fruiting phase, namely Anthrococeros malayanus (Raffles, 1822), Anthrococeros albirostris (Shaw & Nodder, 1807), and Buceros rhinoceros (Linnaeus 1758) while fig tree in non-fruiting phase is only visiting by A. malayanus and A. albirostris. There is difference between A. malayanus, A. albirostris and B. rhinoceros in time, duration and frequency of visits on F. crassiramea. The most dominant activity of the third hornbill on F. crassiramea in fruiting phase are foraging rather than perched like on non-fruting phase tree. The result convinced the important of F. crassiramea as food source for hornbill conservation
