Insentif Ekonomi Terhadap USAha Aquaculture

The purpose of this study is to analyze the incentives for aquaculture businesses, one of these efforts is seaweed in Bone, South Sulawesi. Government intervention to develop the aquaculture business can be seen from the incentives provided. Incentives can be subsidized (at nursery) or in the form of protection (when the product is sold in the market). Incentives provided by the government in the form of policies, pay tax breaks or subsidies, have not touched this aquaculture business effectively. It can be seen from the value of the effectiveness of incentives for a commodity that is less than one (0.67). The government has not provided direct subsidies to farmers, unlike the fishing effort to get direct subsidies in the form of fuel prices (fuel oil) are relatively inexpensive for the fishermen. It can be seen from the value of subsidies for farmers who are negative (-0.3)

Is U(1)H_H a Good Family Symmetry?

We analyze U(1)$_H$ as a horizontal symmetry and its possibilities to explain the known elementary-fermion masses. We find that only two candidates, in the context of SU(3)$_c\otimes$SU(2)$_L\otimes$U(1)$_Y\otimes$U(1)$_H$ nonsupersymmetric, are able to fit the experimental result m$_b<<$m$_t$.Comment: 10 pages, Accepted for publication in Z.

Membrane processing of grape must for control of the alcohol content in fermented beverages

The great demand of beverages, both alcohol-free and with low alcohol content, is a great challenge for the production of beverages with controlled alcohol content through the use of sustainable enological practices. The present work addresses this challenge with the processing of grape must by reverse osmosis (RO) for must reconstitution with different sugar contents prior to the alcoholic fermentation. The original must came from grapes grown in Quinta do Quinto, in Santarém, collected after destemming and mechanic crushing, and preserved in a refrigerated chamber at -1.6 °C until processing by RO. The RO processing was carried out in Escola Superior Agrária de Santarém, with a pilot plant equipped with RO spiral wound modules, M38RO, from Alfa Laval, Denmark. The total membrane permeation area is 15 m2. The work pressure was 55 bar. The original must had 23.7 oBrix, a density of 1108 g.L-1, 15.2% (v/v) of probable alcohol, and a conductivity of 2.01 mS.cm-1. The must reconstitution was carried out, by mixing the concentrated grape must with the vegetal water produced by RO (permeate) to obtain beverages with a nominal alcohol content of 5%, 7%, 10% and 13% (v/v). The fermentation average temperature was between 18.2 and 19.7 °C, and the final density rounded about 993 g.cm-3. The beverages were analysed by different parameters, including total polyphenols, total anthocyanins, colour intensity and hue, the coordinates CIELab, alcohol content, total acidity, volatile acidity, pH, free SO2 and total SO2. The attributes of the beverage, corresponding to the visual appearance, aroma and taste senses, as well as the overall judgment were evaluated by the tasters. The proposed method can produce beverages with controlled low alcohol content. The decrease of the alcohol content led to lower content of polyphenols compounds which influenced the sensory evaluation.info:eu-repo/semantics/publishedVersio

Upaya Meningkatkan Pemahaman Isi Dongeng dengan Menggunakan Strategi Know-want To Know-learned (K-w-l) pada Kelas Iii-a Sdn Rangkah 1 Kecamatan Tambaksari Surabaya

Tujuan penelitian ini adalah mengkaji penggunaan strategi Know-Want to know-Learned (K-W-L) untuk memahami isi dongeng pada pembelajaran Bahasa Indonesia siswa kelas III, pencapaian hasil belajar siswa, dan kendala - kendala yang dialami selama proses pelaksanaan pembelajaran berlangsung. Penelitian ini menggunakan rancangan penelitian tindakan kelas dengan metode kualitatif. Subyek penelitian ini adalah siswa kelas III-A SDN Rangkah 1 Tambaksari Surabaya yang berjumlah 32 siswa. Data pada penelitian ini diperoleh dari hasil pengamatan penggunaan strategi KWL untuk memahami isi dongeng, hasil belajar siswa, dan catatan lapangan. Hasil pengumpulan data dianalisis dengan menggunakan teknik analisis deskripsi kualitatif. Hasil nilai ketercapaian kegiatan pembelajaran mengalami peningkatan, dari 75,89% pada siklus I menjadi 91,07% pada siklus II. Terjadi pula peningkatan persentase ketuntasan klasikal dari siklus I ke siklus II, yaitu dari 53,1% menjadi 87,5%. Sementara itu selisih rata-rata kelas mencapai 7,18 poin; dari 73,5 pada siklus I menjadi 80,68 pada siklus II, dengan bertambahnya jumlah siswa yang mendapatkan nilai mencapai atau melampaui KKM, yaitu dari 17 siswa pada siklus I menjadi 28 siswa pada siklus II. Dari hasil tersebut, dapat disimpulkan bahwa penerapan strategi Know-Want to know-Learned (K-W-L) dalam memahami bacaan berupa dongeng berteks panjang dapat meningkatkan hasil belajar siswa kelas III-A di SDN Rangkah 1 Tambaksari Surabaya
