On the deviation and the type of certain local Cohen–Macaulay rings and numerical semigroups
No full textIn J. Herzog and E. Kunz (1973) [6] it was shown that for any pair (d,t) is an element of N x N+ with (d,t) not equal(1,1) there exists a local Cohen-Macaulay ring R having deviation d(R) = d and type t(R) = t. By E. Kunz (1974) [7] the case d(R) = 1,t(R) = 1 cannot occur. In this paper certain Cohen-Macaulay rings are studied for which there are close relations between deviation, type and embedding dimension. Similar relations for other classes of local rings have been proved in the recent paper by L. Sharifan (2014) [15]. Our relations will be applied to numerical semigroups (or equivalently monomial curves) and lead also to some further cases, generalizing E. Kunz (2016) [8] with ring-theoretic proofs, in which a question of H. Will (1978) [16] has a positive answer. (C) 2017 Published by Elsevier Inc
On certain birational invariants of the Fermat curves
No full textAbstractFor an integer m≥3 let Km=Q(x,y)(xm+ym=1) be the m-th Fermat field over Q. We study, in the case of Fermat fields, the groups of integral differentials introduced by Kähler [E. Kähler, Geometria aritmetica, Annali di Mat. 45 (1958)] and Bost [R. Berndt, Arithmetisch ganze Differentiale, Abh. Math. Sem. Univ. Hamburg 47 (1978) 249–270] for arithmetic function fields and compute them for small m. An essential step of our considerations is the explicit description of the discrete valuation rings with quotient field Km which are essentially of finite type and smooth over Z
ANALISIS KELAYAKAN USAHA TANI CABAI MERAH DI LAHAN PASIR PANTAI KECAMATAN PANJATAN KABUPATEN KULON PROGO
No full textThis study was conducted in Desa Bugel, Kecamatan Panjatan, Kabupaten Kulon Progo on January-February 2016. This study aimed to investigate the income and farming appropriateness of red chili in Kecamatan Panjatan, Kabupaten Kulon Progo. The method of sampling in this study applied the simple random sampling in the number of 30 red chili farmers. Meanwhile, the method of choosing population in this study utilized purposive sampling. Analysis. Data were analyzed using analysis of cost, analysis of receipt and analysis of income whereas the hypothesis testing used t-Test to assess statistical appropriteness of red chili farming. The result of this study showed that the total number of cost average in red chili farming per season achieved Rp 14 585 467,6 or Rp 51 478 912,8 per hectare, whereas the total number receipt average in red chili farming per season achieved Rp 40 696 905 or Rp 143 703 763 per hectare, and the average of income per farming was Rp 26 111 437.4 or Rp 92 224 850,2. Meanwhile the hyphothesis assessment showed R/C ratio > 1 that was 2,79 and t-Test showed the significant result, thus the red chili farming in Kecamatan Panjatan was appropriate to cultivate.Keyword: red chili, income, analysis of appropriatenes
Analisis Faktor Yang Berhubungan Dengan Dukungan Keluarga Ibu Positiv Hiv Dalam Pelaksanaan Community Home Based Care Di Surabaya
No full textIntroduction : Family support is one of the vital important in implementing Community Home Based Care (CHBC). Some of family member don’t give their family support to the mother HIV positive due to their fear of HIV transmission. Based on Friedman, family support is influenced by knowledge, age, gender, socio-economical, and kinship with the patient factors. The role of family as support system in giving care and aid for the family member that suffer from HIV/AIDS. The purpose of this study is to identify the correlation between family support and the knowledge, age, gender, socio-economical status, and the kinship with patient. Method : the design of this study is correlation descriptive with cross sectional approach. The population are 20 of family member of mother with HIV positive. The sample is 17 of family member of mother with HIV positive chosen with total sampling, with 3 of family member were dropped out. The independents variables of this study are knowledge, age, gender, socio-economical status, kinship with patient. And the dependent variable is family support. Result : the result showed the correlation between family support and knowledge (p=0,001 r=0,717), age (p=0,036 r=0,510), gender (p=0,485 r=0,182), socio-economical status (p=0,010 r=0,604), kinship with the patient (p=0,109 r=0,402). The conclusion is family support is important for people live with HIV/AIDS to enhance their quality of life. Further research is needed to research other factors in implementing Community Home Based Care for HIV patient

PENGARUH PENGETAHUAN KONSUMEN DAN KESADARAN HALAL TERHADAP KEPUTUSAN PEMBELIAN PRODUK KOSMETIK MEREK MAYBELLINE DI KELURAHAN SIALANG SAKTI PEKANBARU
No full textTujuan dalam penelitian ini adalah untuk mengetahui pengaruh secara parsial
dan simultan pengetahuan konsumen dan kesadaran halal terhadap keputusan
pembelian produk kosmetik merek Maybelline di Kelurahan Sialang Sakti Pekanbaru.
Penelitian ini dilakukan di Perumahan Pondok Mayang Pekanbaru. Jumlah sampel
dalam penelitian adalah 100 orang responden dengan metode pengambilan sampel
purposive sampling. Metode dalam penelitian ini adalah deskriptif kuantitatif dengan
regresi linier berganda. Hasil dari penelitian yang telah dilaksanakan didapatkan
persamaan ragresi linier berganda Y = -2,114+ 0,884X1 + 0,209X2 + e. Hasil Fhitung
sebesar (126,102) > Ftabel (3,090) dengan Sig. (0,000) < 0,05. Artinya pengetahuan
konsumen dan kesadaran halal memiliki pengaruh terhadap keputusan pembelian pada
produk kosmetik merek Maybelline di Kelurahan Sialang Sakti Pekanbaru. Dengan
nilai R berarti terdapat hubungan antara pengetahuan konsumen dan kesadaran halal
memiliki pengaruh terhadap keputusan pembelian pada produk kosmetik merek
Maybelline sebesar 85%. Nilai R Square berarti variabel keputusan pembelian dapat
dijelesakan oleh variabel pengetahuan konsumen dan kesadaran halal sebesar 72,2%
dan 27,8% dipengaruhi oleh variabel lain.
