Kebutuhan Sistem Informasi Komunikasi Pasar Tepat Waktu Bagi Pemasaran Lokal, Domestik, dan Ekspor Produk Agribisnis Kabupaten Kerinci

Fenomena yang terjadi selama ini pengusaha agribisnis/petani produsen belum menggunakan jasa sistem informasi komunikasi pasar tepat waktu. Sehingga pengusaha agribisnis tidak mengetahui harga pasar yang sebenarnya sehingga menjual produk dengan harga murah, produsen akan selalu dirugikan karena menjual produk dengan harga murah, pendapatan petani produsen tetap selalu rendah dan hidup di bawah garis kemiskinan. Penelitian ini menggunakan pendekatan kualitatif dengan metode riset partisipatoris yaitu kegiatan yang dilakukan oleh peneliti mengikuti dan memahami serta membahas masalah-masalah yang dihadapi masyarakat produsen/pedagang agribisnis dan juga melakukan pola pembinaannya. Untuk itu, peneliti bertemu langsung dengan masyarakat produsen/pedagang agribisnis dan menjalin persahabatan dengan sejumlah anggota masyarakat dalam menyelesaikan permasalahan penelitian. Metode ini berdampingan dengan menggunakan pendekatan Descriptive analysis untuk menjawab masalah yang memerlukan keterangan, gambaran dan sejenisnya secara faktual dan aktual. Populasi dalam penelitian ini adalah populasi terhingga. Sampel Penelitian ada di wilayah sentra produksi agribisnis Kecamatan Kayu Aro Kabupaten Kerinci. Hasil penelitian, pengusaha agribisnis terutama petani agribisnis sebagian belum menggunakan komunikasi pasar tepat waktu dan sebagian sudah menggunakan komunikasi pasar tepat waktu. Bagi pedagang perantara sudah melakukan sistem informasi komunikasi pasar tepat waktu baik untuk pemasaran lokal, domestik dan ekspor dan dapat menggunakannya dengan baik dan benar. Pengusaha agribisnis sudah dibina untuk dapat mengetahui harga pasar dengan menggunakan media komunikasi telepon rumah dan handphone. Oleh karena itu petani produsen dan pedagang agribisnis agar membentuk jejaring informasi komunikasi pasar pada semua pedagang agen di luar provinsi dan semua pedagang agen di luar pulau dan membentuk wadah persatuan informasi harga serta bersatu dalam menentukan harga pasar dan tidak saling menjatuhkan harga

Photoredox-Catalyzed Decarboxylative Alkylation of Silyl Enol Ethers To Synthesize Functionalized Aryl Alkyl Ketones

Photoredox-catalyzed decarboxylative alkylation of silyl enol ethers has been developed. Diverse functionalized aryl alkyl ketones were afforded in modest to good yields using <i>N</i>-(acyloxy)­phthalimide as an easy access alkyl radical source under mild and operationally simple conditions. The excellent performance of drug molecules such as fenbufen and indomethacin and naturally occurring carboxylic acids such as stearic acid and dehydrocholic acid further demonstrated the practicability of the reaction

Copper-Catalyzed Intermolecular Reductive Radical Difluoroalkylation–Thiolation of Aryl Alkenes

A novel radical-involved alkene difunctionalization catalyzed by the copper/B₂pin₂ system has been developed, leading to the difluoroalkylation–thiolation of aryl alkenes. The use of B₂pin₂ as an organic reductant enables the simultaneous installation of a C­(sp³)–C­(F₂R) bond and a C­(sp³)–S­(R) bond across the CC bond of aryl alkenes by utilizing two electrophilic reactants. The reaction exhibits broad substrate scope, excellent diastereoselectivity, and moderate to good yields. Moreover, the reaction can be conducted on a gram scale with good yield achieved

PyrrolylBODIPYs: Syntheses, Properties, and Application as Environment-Sensitive Fluorescence Probes

Four pyrrole <b>B</b>-ring-functionalized pyrrolylBODIPYs and their <b>B</b>-ring unsubstituted analogues were synthesized from easily accessible starting 5-halo-2-formylpyrroles and were characterized by nuclear magnetic resonance, high-resolution mass spectrometry, X-ray analysis, and optical/electronic properties. In great contrast to the substitution(s) at the other two pyrrolic units, electron-donating substituent(s) at pyrrole <b>B</b>-ring bring significant blue shift of the absorption and emission bands. Cyclic voltammetry and density functional theory calculations indicate that this blue shift may be attributed to the increased highest occupied molecular orbital and the lowest unoccupied molecular orbital energy levels and the overall increase in the energy band gaps. These pyrrolylBODIPYs generally show intense absorption (centered at 570–624 nm) and fluorescence emission (582–654 nm) in nonpolar solvents. A gradual decrease in the fluorescence intensity was observed for these dyes with the increase in solvent dipolar moment, which combines with the red to far-red absorption/emission, rendering these pyrrolylBODIPYs potential applications as environment-sensitive fluorescence probes as demonstrated in this work for bovine serum albumin

Comparative Analysis of Duckweed Cultivation with Sewage Water and SH Media for Production of Fuel Ethanol

<div><p>Energy crises and environmental pollution have caused considerable concerns; duckweed is considered to be a promising new energy plant that may relieve such problems. <i>Lemna aequinoctialis</i> strain 6000, which has a fast growth rate and the ability to accumulate high levels of starch was grown in both Schenk & Hildebrandt medium (SH) and in sewage water (SW). The maximum growth rates reached 10.0 g DW m⁻² day⁻¹ and 4.3 g DW m⁻² day⁻¹, respectively, for the SH and SW cultures, while the starch content reached 39% (w/w) and 34% (w/w). The nitrogen and phosphorus removal rate reached 80% (SH) and 90% (SW) during cultivation, and heavy metal ions assimilation was observed. About 95% (w/w) of glucose was released from duckweed biomass hydrolysates, and then fermented by Angel yeast with ethanol yield of 0.19 g g⁻¹ (SH) and 0.17 g g⁻¹ (SW). The amylose/amylopectin ratios of the cultures changed as starch content increased, from 0.252 to 0.155 (SH) and from 0.252 to 0.174 (SW). <i>Lemna aequinoctialis</i> strain 6000 could be considered as valuable feedstock for bioethanol production and water resources purification.</p></div
