Abstract

Pada penelitian ini dibuat simulasi desain antena mikrostrip dengan optimasi menggunakan algoritma genetika yang disesuaikan dengan ukuran satelit nano. Salah satu kriteria dari satelit tersebut adalah memiliki antena dengan frekuensi 2,4 GHz. Antena mikrostrip ini menggunakan pencatuan aperture coupled. Algoritma genetika diaplikasikan untuk mengoptimasi tiga parameter antena yaitu panjang patch, lebar patch dan panjang slot terhadap impedance matching antena dilihat dari sisi VSWR. Sedangkan parameter seperti panjangfeeding, lebar feeding, lebar slot,t inggi substrat, tinggi patch telah ditentukan berdasarkan perhitungan awal antena mikrostrip. Sedangkan fungsi fitness diturunkan dari pemodelan transmision line. Optimasi ini dilakukan dalam matlab dan CST microwave studio. Hasil simulasi menunjukkan bahwa dengan mengubah tiga parameter yang dioptimasi, simulasi antena ini dapat menenuhi kriteria antena yaitu nilai VSWR<2denganreturn loss<-10 dB dengan panjang patch, lebar patch dan panjang slot yang dibangkitkan secara random. Sedangkan perbandingan hasil optimasi di matlab dan simulasi CST microwave studio terdapat perbedaan nilai VSWR.

Abstract

ABSTRAK Penelitian ini bertujuan untuk mendeskripsikan unsur naratif wawacan, gambaran (citra) perempuan Sunda dan aspek sosial yang terdapat dalam Wawacan Carios Munada. Metode yang digunakan adalah metode deskriptif, dengan teknik dokumentasi. Berdasarkan hasil analisis, diketahui bahwa Wawacan Carios Munada memiliki unsur naratif yang lengkap seperti tema, latar, alur, tokoh, dan motif cerita. Selain itu, juga menunjukan adanya tokoh perempuan dalam panggung kehidupan masyarakat Sunda zaman dulu yang berperan sebagai seorang istri (baik istri resmi/istri padmi maupun istri tidak resmi/selir) dan seorang ibu. Kedua peran tersebut menjadikan tokoh perempuan dalam Wawacan Carios Munada hanya jadi pelengkap kaum laki-laki. Kenyataan tersebut merupakan akibat dari tumbuhnya feodalisme yang mempengaruhi kehidupan masyarakat Sunda. ABSTRACTThis study aimed to describe the narrative elements, the image of Sundanese women, and the social aspects contained in Wawacan Carios Munada. The method used in this study is a descriptive method with documentation technique. Based on the analysis, it is known that Wawacan Carios Munada has complete narrative elements such as the theme, setting, plot, characters, and motif of story. Moreover, it also shows the presence of female character in the life of ancient Sundanese people in the form of wives (padmi wife official wife and concubine) and mothers. Both roles of female characters in Wawacan Carios Munada only serve as complementary to men. The reality is the result of feudalism that affects Sundanese people.

Abstract.Problem Based Instruction is kind of learning model which introducing students to a real and meaningful problems. The phases of PBI are (1) orientating the students to a problem, (2) organizing the students to learn, (3) guiding the individual or group research, (4) developing and presenting the result, (5) analyzing and evaluating problem solving process. This research aims to develop the set of learning, such as syllabus, lesson plan, student book, student worksheet, and evaluation test by using Thiagarajan Model which consist of four steps such as define, design,develop, and disseminate. But this research just use the three of them, without disseminate step. SMP Negeri 3 Jember is elected as the research place. The coefficient validities of syllabus, lesson plan, student book, student worksheet, and evaluation test respectively are 0,975; 0,982; 0,984; 0,980; and 0,992. Since all of those coefficient more than 0,6, so we can conclude that the set of learning is valid and proper to be used. The reliability coefficient of evaluation test is 0,612717. Besides, the each item validity of evaluation test also showed a high number. There are five item problems where the coefficient validities of each number are 0,819533; 0,98036; 0,958226; 0,894288; and 0,960059.

Abstract

Banjir yang terjadi di Kawasan Sungai Sringin khususnya Kawasan Industri Terboyo dan Kawasan permukiman Dukuh Ngilir Kelurahan Trimulyo Kecamatan Genuk diakibatkan oleh genangan pasang surut air laut (rob) serta limpasan air hujan. Daerah hilir Sungai Sringin mempunyai elevasi lahan lebih rendah dari muka air pasang, hal ini mengakibatkan air sungai tidak mampu mengalir secara gravitasi sehingga penanganan banjir yang tepat untuk kawasan Sungai Sringin adalah menggunakan sistem polder (non-gravitasi). Sistem polder adalah sistem penanganan drainase perkotaan dengan cara mengisolasi daerah yang dilayani (catchment area) terhadap masuknya air dari luar sistem. Komponen sistem polder meliputi tanggul, kolam retensi, sistem pompa dan pintu, serta perbaikan drainase saluran induk Sungai Sringin. Luas kolam retensi 17,795 hektar dengan kedalaman 3,5 meter. Jenis pompa yang digunakan adalah gate pump berjumlah 8 buah, terdiri dari empat buah masing-masing 10 m3/detik dan empat buah masing-masing 2,5 m3/detik. Gate pump yang digunakan adalah pintu tipe sliding gate berjumlah enam buah pintu dengan lebar masing-masing pintu tiga meter. Perbaikan penampang sungai dengan rencana lebar sungai 30 meter pada hilir saluran dan 28 meter pada hulu saluran. Perkuatan dinding sungai direncanakan dengan dinding penahan tanah pasangan batu kali. Dinding laut (revetment) direncanakan di garis pantai untuk mengisolasi air laut agar tidak masuk ke dalam sistem polder. Total rencana anggaran biaya yang diperlukan dalam Pengembangan Drainase Sistem Polder Sungai Sringin adalah Rp. 230.210.000,00 (Dua ratus tiga puluh milyar dua ratus sepuluh juta rupiah) dengan lama pekerjaan 22 minggu.
