<p>Kopi Gayo merupakan salah satu komoditi pertanian utama provinsi Aceh selain kopi, nilam, pinang dan kelapa sawit. Upaya mencapai rantai pasok yang berkelanjutan, perlu diperhatikan tiga aspek yang menjadi pilar yaitu ekonomi, sosial dan lingkungan. Manajemen rantai pasok pertanian terutama kopi Gayo umumnya lebih sulit ditangani dibandingkan dengan produk manufaktur karena produk pertanian memiliki sifat cepat rusak, ukuran bervariasi, musiman, lokasi tersebar dan skala kecil, sehingga sangat rentan terhadap risiko kerugian bagi pelakunya. Fakta saat ini menunjukkan bahwa beberapa aspek belum menunjukkan kondisi keberlanjutan, seperti pada indikator profit usaha petani, keterampilan pelaku, penggunaan air pada proses produksi jauh di atas ambang batas, pengelolaan risiko rantai pasok serta pola hubungan keterkaitan antar pelaku. Tujuan dari penelitian ini mengetahui faktor-faktor risiko yang paling berpengaruh dan analisis interaksi antar pelaku untuk bersama-sama mengelola risiko dalam struktur rantai pasok kopi Gayo. Metode yang digunakan adalah sintesis logika <em>Fuzzy Analytichal Hierarchy Process </em>(F-AHP) dan proses hirarki analitik, sedangkan analisis interrelasi dilakukan secara deskriptif. Hasil <em>Fuzzy AHP</em> menunjukkan bahwa pada petani, risiko terbesar adalah mutu dan budidaya, pada pedagang pengepul adalah pemenuhan mutu dan harga, pada agroindustri risiko terbesar adalah mutu dan harga.</p><p class="8AbstrakBahasaIndonesia"> </p><p><strong>Kata Kunci</strong>: Agroindustri Kopi Gayo; <em>Fuzzy Analytichal Hierarchy Process</em>; Risiko Rantai Pasok</p>

Published: February 2019

Purpose: To describe prenatal nutrition care currently delivered by Family Health Teams (FHTs) and Community Health Centres (CHCs) in Ontario, from the perspectives of health care providers, and to identify opportunities for improving care. Methods: Ten 1-hour, interdisciplinary focus groups were conducted in FHTs and CHCs, involving a total of 73 health care providers. Focus groups ranged in size from 3 to 11 team members, and at least 3 different professions participated in each group. The shared perspectives and experiences on prenatal nutrition care were collected using a semi-structured interview guide and analyzed using thematic analysis. Results: Limited time was spent on prenatal nutrition education and counselling. Two themes emerged describing gaps in care: (i) providing care in “borderline” high-risk pregnancies (i.e., impaired glucose tolerance) and (ii) providing care around gestational weight gain. Providers envisioned improving services offered by increasing preventative care, empowering providers to provide more nutrition care, facilitating patient self-care, and building a 1-stop shop “medical home”. Conclusions: This study’s findings can guide strategies to mobilize current nutritional knowledge into routine prenatal care, and the shared vision for improvement will inform the routes for new practice that are supported by health care professionals.

The occurence of hydrocarbon seepage in some places, indicate that hydrocarbon have been formed although its distribution is not clearly known. The gravity Bouguer anomaly resulted two groups of rock units: the group of 40 mGal up to 120 mGal gravity anomaly represent ultramafic rocks, and group of 30 mGal up to -80 mGal gravity anomaly reflected a sedimentary rocks basin. The subsurface modeling of the rock density can be grouped into three layers: the Cenozoic (2.5-2.55 gr/cm³ density), the Mesozoic (2.6-2.7 gr/cm³ density), and the Basement ( 2.8-2.9 gr/cm³ density). Elongated and vertical closure are reflected by anomaly 0-2 mGal with density 2.5 gr/cm3 to 2:55 mGal which is supposed to be oil and gas structures. The Source rock is characterized by 0 to -10 mGal anomaly interpreted as oil kitchen at sub-basin area. Location of the reservoir rock is assumed in the Cenozoic layer on Salodik Group with density of 2.5 gr/cm³. The Basement is estimated at depth of 3.5-4 km, derived from the Group of metamorphic and volcanic rocks.Keyword: Gravity, basin, residual anomaly, fault, anticline.
