Abstract

Organic waste is a kind of waste that much cause pollution, although this type of waste can be recycled by nature but still cause problems if left unchecked . Wood, for an example we bring here, is a natural resource that is widely used by humans , especially in Indonesia for home furnishings and interior elements ( home accessories ). From the process of making furniture it produced a lot of waste, a kind of sawdust called gerajen (java) and it only ended up to burned (incinerate) or even left to rot away. The problems that exist are lack the utilization of sawdust waste that can be transformed to product to add to the aesthetic and economic values , the lack of utilization of waste product development and innovation shape as well as to cultivate and experiment through design innovation for sawdust utilization into a product. The objective of this research are to bring both aesthetic and economic value of sawdust waste as an effort to reduce pollution resulting from incineration of sawdust , provides new insights for the processing of waste, sawdust as alternative materials to create a product that the added value aesthetically and economically. The methods undertaken through several processes such as obtained from trials or experiments. From variety of data obtained would lead us to design concept of finished product, doing some experiments processing sawdust mixed with some other material to produce a product that can provide added value to the waste.

Abstract

Leaders are required to be able to influence subordinates in carrying out an order without coercion so that subordinates/members will voluntarily work according goals as directed by the leader of the institution. Transactional Leadership is developed based on the level of human needs such as rewards, promotions or other awards. The leaders in Transactional Leadership tend to be more passive because he/she has gave full authority to subordinates in carrying out the tasks. Motivation is developed from the theory of Clelland covering Achievement Motivation, Affiliation Motivation, Competence Motivation and Power Motivation. These four things are some forms of motivation which determines the pattern of the motivation of members of the organization. Job satisfaction is the emotional stage of the subordinates/members which happened or not will concern about the meeting point between the remuneration that they expected compared to what they have received. In various studies variables Transactional Leadership, Motivation and Job Satisfaction were found to have a close relationship each other and this study is to combine those variables into a model and tested to further clarify the pattern of the relationship between these three variables. The object of this quantitative research is a working unit region in East Java Province, Pamekasan Police Department. Sampling technique that being used is non-probability sampling. The type of method of this research is purposive sampling. The sample were 89 respondents, for those who served as members of the police and civil workers in Pamekasan Police Department. Data were collected using a questionnaire. The analysis technique used is regression analysis with SPSS software. The analysis showed that the variables Transactional Leadership is having effect on job satisfaction when mediated by Motivation variable.

Abstract

Pelengkungan yang terjadi pada sebuah kabel serat optik sangat berpotensi menimbulkan rugi daya yang cukup serius dan lebih jauh lagi menyebabkan pecahnya serat optik. Oleh karena itu perlu dilakukan pengukuran pengaruh pelengkungan serat optik terhadap rugi daya yang dihasilkan ketika serat optik dilengkungkan.Penelitian ini bertujuan untuk mengetahui perubahan intensitas cahaya keluaran yang melalui serat optik plastik. Skripsi ini hanya membahas mengenai perhitungan keluaran cahaya yang telah dipengaruhi oleh lekukan pada serat optik.Dari analisa yang dilakukan dengan panjang kabel fiber optik 100 m, redaman sebesar 0,2 dB/km dan radius pelengkungan yang bervariasi dengan radius pelengkungan sebesar 15 cm, 10 cm, 7 cm, 5 cm dan 2,25 cm, maka diperoleh rugi-rugi pelengkungan serat optik berturut -0,366 db, -0,312, -0,689, -0,914 , -1,658.

Abstract

Antenna mikrostrip merupakan antenna yang memiiki keunggulan dalam bentuk fisik yakni antenna dengan bentuk kecil sehingga mudah diintegerasikan. Selain bentuk yang kecil antenna ini juga memiliki kekurangan seperti bandwidth sempit dan gain yanag rendah. Salah satu mengatasai tersebut, antenna mikrostrip dapat dirancang dengan teknik array. Teknik array pada perancangan antenna mikrostrip didesain untuk keperluan frekuensi 850 MHz. frekuensi ini biasa digunakan oleh penyedia layanan komunikasi untuk keperluan LTE. Bahan yang digunakan adalah PCB epoxy (FR4) double layer dengan ketebalan bahan 1,3 mm dan konstanta dielektrik sebesar 4,7. Bentuk patch yang dibuat adalah segiempat dan lingkaran. Antena mikrostrip tersebut diuji untuk mendapatkan nilai frekuensi resonansi, VSWR dan pola radiasi yang kemudian hasilnya dibandingkan dengan hasil simulasi menggunakan perangkat lunak simulator mikrostrip IE3D. Pada pengujian diperoleh hasil untuk antena mikrostrip array segiempat: frekuensi resonansi sebesar 930MHz dan VSWR sebesar 1,03.

Abstract

Penelitian ini membahas tentang perancangan antena mikrostrip dipol dengan fraktal Cohen-Minkowski untuk frekuensi 433 MHz yang dapat diaplikasikan pada kanal Industrial, Scientific, and Medical (ISM) Band. Antena mikrostrip menggunakan substrat FR-4 dengan ketebalan 1,6 mm dan impedansi saluran 75 . Perancangan dan simulasi antena menggunakan Software AWR Microwave Office 2004. Hasil perancangan menggunakan fraktal Cohen-Minkowski dapat memperkecil ukuran antena sebesar 29% iterasi-1, dan 40% iterasi-2 sehingga memberikan nilai VSWR sebesar 1,02 untuk dipol tanpa iterasi, 1,74 untuk dipol fraktal iterasi-1, dan 1,26 iterasi dipol fraktal. Return loss yang dihasilkan dari perancangan antena adalah -37,7 untuk dipol tanpa iterasi, -11,29 untuk dipol fraktal iterasi-1, dan -18,69 untuk fraktal iterasi-2. Kemudian gain yang diperoleh dari perancangan antena adalah 4,78 dB untuk dipol tanpa iterasi, 4,91 dB untuk dipol fraktal iterasi-1, dan 4,78 dB untuk dipol fraktal iterasi-2. Pola radiasi yang dihasilkan dari antena adalah searah.

Abstract

Fokus penelitian ini adalah pada pengendalian DC-DC boost converter tipe Voltage Doubler. Metode kendali saklar menggunakan modulasi lebar pulsa yang tergeser sebesar 1800. Untuk mendapatkan tegangan keluaran yang sesuai, diterapkan sistem pengendali tegangan keluaran. Kendali tipe proporsional ditambah integral diimplementasikan menggunakan mikrokontroler jenis STM32F1038CT. DC-DC boost converter tipe Voltage Doubler terkendali tegangan keluaran divalidasi melalui simulasi komputasi dengan perangkat lunak Power Simulator dan sebagai tahap akhir akan dilakukan implementasi pada perangkat keras di laboratorium. Berdasarkan simulasi dan implementasi, DC-DC boost converter tipe Voltage Doubler mampu menghasilkan tegangan keluaran sesuai dengan yang diinginkan, yaitu dua kali lebih besar dari tegangan keluaran DC-DC boost converter konvensional.
