Analisa Greenwater Akibat Gerakan Offshore Security Vessel

Analisa Tugas Akhir ini, terdiri atas beberapa tahapan. Yang pertama yaitu perancangan struktur Offshore Security Vessel (OSV) dengan bantuan software MAXSURF guna mendapatkan Lines Plan. Offset data yang diperoleh digunakan dalam pemodelan menggunakan MOSES, kemudian dilakukan analisa gerak OSV dalam gelombang regular dan dinyatakan dalam grafik RAO. Analisa gerak relatif vertikal haluan dihitung dari RAO gerakan, dan kemudian melakukan evaluasi perilaku di gelombang acak dengan analisis spektra gelombang. Dari analisa spektra didapatkan parameter greenwater sehingga dapat dihitung peluang, intensitas dan tekanan greenwater. Dari hasil analisa diperoleh RAO gerak vertikal Offshore Security Vessel (OSV) pada gelombang reguler yang dipengaruhi oleh kecepatan, kondisi muatan dan arah gelombang. Peluang terjadinya greenwater terbesar terjadi pada sudut datang gelombang following sea (0o) dimana harga terbesar terjadi pada ω = 0.2 rad/sec dengan periode 29 detik mencapai 0.477. Intensitas greenwater terbesar terjadi pada saat sudut datang gelombang following sea (0o) adalah sebanyak 59.265 per jam dan 0.378 per detik. Tekanan greenwater terbesar terjadi pada saat sudut datang gelombang head sea (180o) sebesar 1678x10-6 MPa. Dengan nilai tersebut, deck mampu menahan beban akibat tekanan greenwater

Pengambilan Keputusan oleh Istri Peternak pada Peternakan Sapi Potong di Kabupaten Banyumas

This research aims to analyze the influence of education, age, and the amount of working hours of wives of beef cattle farmers on decision-making, which includes purchasing livestock and selling cattle. The research was conducted using a survey method. The determination of the sample size of respondents used the Slovin formula with a margin of error of 10%, resulting in a total of 81 respondents. Data analysis was performed using descriptive analysis and Binary Logistic Regression analysis. The results of the descriptive analysis indicate that the majority of wives of beef cattle farmers had completed elementary school education (56%) and junior high school education (21%), were aged between 31 and 64 years (88%), owned fewer than 4 cattle heads (74%), had 1-3 family members (41%), and had a working hours allocation of less than 0.5 hours or less than 30 minutes (41%). Their involvement in decision-making showed that 46% were in the high category, and 54% were in the low category. The results of the Binary Logistic Regression analysis indicate that the level of education has no significant influence on decision-making (0.474), age has no significant influence on the decision-making of the farmer's wives (0.298), the number of cattle ownership has a significant influence on decision-making (0.088), the number of family members has no significant influence on decision-making (0.138), and the amount of working hours has a significant influence on the decision-making of farmer's wives (0.1).Penelitian ini bertujuan untuk menganalisis pengaruh pendidikan, usia, dan jumlah jam kerja istri peternak sapi potong terhadap pengambilan keputusan, termasuk pembelian ternak dan penjualan sapi. Penelitian ini dilakukan dengan menggunakan metode survei. Penentuan ukuran sampel responden menggunakan rumus Slovin dengan margin kesalahan sebesar 10%, sehingga menghasilkan total 81 responden. Analisis data dilakukan dengan menggunakan analisis deskriptif dan analisis Regresi Logistik Biner. Hasil analisis deskriptif menunjukkan bahwa sebagian besar istri peternak sapi potong telah menyelesaikan pendidikan dasar (56%) dan pendidikan menengah (21%), berusia antara 31 hingga 64 tahun (88%), memiliki kurang dari 4 ekor sapi (74%), memiliki 1-3 anggota keluarga (41%), dan alokasi jam kerja kurang dari 0,5 jam atau kurang dari 30 menit (41%). Partisipasi mereka dalam pengambilan keputusan menunjukkan bahwa 46% berada dalam kategori tinggi, dan 54% berada dalam kategori rendah. Hasil analisis Regresi Logistik Biner menunjukkan bahwa tingkat pendidikan tidak memiliki pengaruh signifikan terhadap pengambilan keputusan (0,474), usia tidak memiliki pengaruh signifikan terhadap pengambilan keputusan istri peternak (0,298), jumlah kepemilikan sapi memiliki pengaruh signifikan terhadap pengambilan keputusan (0,088), jumlah anggota keluarga tidak memiliki pengaruh signifikan terhadap pengambilan keputusan (0,138), dan jumlah jam kerja memiliki pengaruh signifikan terhadap pengambilan keputusan istri peternak (0,1)

Socio Demographic Factors Influencing the Income of Native Chicken Farming in Rural Area of Ciamis Regency

Sentul chicken is one of indigenous poultries maintained by most people in Ciamis Regency, West Java Province. This study aimed at determining the influence of socio demographic factors on the income generated from Sentul chicken farming in Ciamis Regency. A survey method was conducted to the members of seven farmer groups institutionally assisted by the Ciamis Regency Government Unit. The descriptive statistics and multiple linear regression analysis were used to describe the profile of respondents and to analyze the influence of socio demographic factors on the income generated from Sentul chicken farming. The results showed that the farmers' length of education was 11.8 years with 5.8 years experience raising the Sentul chicken while the farm size was averagely 9 heads of chicken. The Sentul chicken farmmaintained in 70 days with semi-intensive production system has generated income ranging from IDR 756,000 to IDR 19,900,000. Farming experience and farm size significantly influenced the income generated from Sentul chicken farming. Increase the farming experience of Sentul chicken farmers and enlarging Sentul chicken farm size with semi-intensive production system may improve the income generated from Sentul chicken farming in Ciamis Regency

Mapping genomic loci implicates genes and synaptic biology in schizophrenia

Schizophrenia has a heritability of 60-80%1, much of which is attributable to common risk alleles. Here, in a two-stage genome-wide association study of up to 76,755 individuals with schizophrenia and 243,649 control individuals, we report common variant associations at 287 distinct genomic loci. Associations were concentrated in genes that are expressed in excitatory and inhibitory neurons of the central nervous system, but not in other tissues or cell types. Using fine-mapping and functional genomic data, we identify 120 genes (106 protein-coding) that are likely to underpin associations at some of these loci, including 16 genes with credible causal non-synonymous or untranslated region variation. We also implicate fundamental processes related to neuronal function, including synaptic organization, differentiation and transmission. Fine-mapped candidates were enriched for genes associated with rare disruptive coding variants in people with schizophrenia, including the glutamate receptor subunit GRIN2A and transcription factor SP4, and were also enriched for genes implicated by such variants in neurodevelopmental disorders. We identify biological processes relevant to schizophrenia pathophysiology; show convergence of common and rare variant associations in schizophrenia and neurodevelopmental disorders; and provide a resource of prioritized genes and variants to advance mechanistic studies.11Nsciescopu
