4. ANALYSIS AND DESIGN
4.1 Inception Phase
One of the main artifacts produced in this phase is the Vision document. This document describes the organization / project management and project scope definition. Project management, especially related to the estimation of the major applications to be developed, number of developer required, included time and costs required. Defining project scope mainly involves the identification and classification of user requirements.
4.1.1 Project Management
An important part of which is related to project management is estimate software size, the number of developers required, working time and costs required. Software size estimation, the number of developers required and working time are counted using Function Point Analysis. While the project cost is calculated by using the ROI and NPV.
a. Function Point Analysis
Lines of Code (LOC): TAFP * 44 = 152.29 * 44 = 67000
Estimate Effort Required:
(1.4*LOC)/1000 = (1.4 * 6700) =11.71 person-month
Estimate Time Required:
(3.0 * person-months1/3) = 3.0 * 11.711/3 = 6.8 ≈ 7 months
b. ROI dan NVP
Net Present Value (NPV Cumulative): Rp 5.901.567
Return on Investment (ROI): 52.24%
Break Even Point (BEP): 2.34 bulan
4.1.2 Project Scope Definition
User requirements are classified into functional requirements and non-functional requirements. The focus for application development lies at functional requirements lists. These functional requirements will be modeled through the UML Use Case Diagram. Methods used in gathering the functional requirements is to conduct interviews with stakeholders.
4.1.2.1. Functional Requirements
List of functional requirements are:
1). Viewing Info
1.1 The system can display information about the ads, profile, headline news, main headline news, North Sulawesi Profile and general articles.
1.2  The system can display links.
1.3 The system can displat visitor counter for each pages.
1.4 The system can display currency value and weather report.
2). Managing Info

1.3 Research Question
The research questions for this paper are 1) how to build architecture application design for web-based 2.0; 2) how to using object oriented paradigm methodology; 3) how to implementing AUP methodology for web-based application.

2.  TEORITICAL CONSIDERATIONS
2.1 Software Lifecycle Models
Software lifecycle models, presented by Schach[1], Sommerville[2], Pressman[3]
Dennis, Wixom dan Tegarden[4] That stages is similar which Bentley dan Whitten[5] proposed. While Kendall dan Kendall[6] proposes 7 (seven) steps for SDLC
Software Engineering Institute – Carnegie Mellon (SEI)[7] proposed a framework which called CMMI for Development (CMMI – DEV).
2.2 Unified Modelling Language (UML)
UML stand for Unified Modeling Language, a modeling notations for software applications. Schach[1] confirms that the UML is a language rather than a method. As a language, UML is used to describe software that is developed with a variety of software development paradigm and methodology. Schach opinion[1] is supported by Sommerville[2] and Pressman[3].
Dennis, Wixom and Tegarden[4], Bentley and Whitten[5], Kendall and Kendall[6]. Fowler[8].
UML is an open standard governed by the Object Management Group (OMG), an open consortium. OMG serves to create standards that support interoperability of object-oriented systems. The latest version of UML is the UML ver 2.0[9]. According to Kruchten[10].
2.3 Agile Unified Process (AUP) Methodology
Unified Process (UP) is one of methodhology for software system development using object-oriented paradigm. UP is a combination of several methodologies which developed by Graddy Booch, James Rumbaugh and Ivar Jacobson[4].
Agile approach began to emerge in software development in the era of the 2000s. Principles of agile approaches can be found at Agile Alliance[11]. Aoyama[12] explains. Jacobson[13] describes ...

3. METODOLOGY
Stages of problem solving methodology AUP, followed all steps proposed by Center of Computer Science (Pusilkom) - University of Indonesia[14]. This Agile UP guide refers to the methodology created by Ambysoft Inc.[15] (see Figure 1 and Figure 2). The phases of analysis and design phases are as follows:
1) Inception, with the activity of defining project scope, cost estimating and scheduling, define risk, making the feasibility of the project and prepare a project execution environment (team work, installation, and so on). Iteration process is done once. Generated artifacts include Vision, Supplementary Specification, dokumen Glossary, Gantt Chart dan Iteration Plan.

Gambar 2. AUP Process Activities (reference link: http://ecl.cs.ui.ac.id/PAUS/index.htm)

2) Elaboration, with the activity of identifying and validating the application architecture. Iteration process can be done one to two times. The resulting artifacts are UML Use Case, Architecture Model (update and snapshot), Architecture Prototype Code, Scenario Test Plan, Business Rule Document, Updated Supplementary and Glossary Document.
3) Construction, with modeling activities, build and test system applications (unit testing) as well as supporting documentation. Iteration process can be done two to eight times. The resulting artifacts are Updated Use Case, Updated Supplementary and Glossary, Domain Model (snapshot), UML Activity Diagram (snapshot), UML Class Diagram (snapshot), CRC Card, UML Sequence Diagram (snapshot), Source Code, Code Documentation, Regression Test Suite, Acceptance Test dan Bugs Report.
4) Transition, with activity testing the system (system integration and user testing), review the application and the system, and installation for the working application system. Iteration process can be done one to two times. The resulting artifacts are System Requirement Specification Document, System Technical Specification Document, User Installation Manual and User Manual, Training Document, Regression Test Suite, User Acceptance Test and Bugs Report (final update).

AUP guide from Pusilkom UI also provides best practice in conducting any activity in each phase. These guidelines also distinguish artifacts generated document, as the main artifact, artifacts, and supporting input artifacts and output artifacts. This guide also provides LCO (Lifecycle Objective) in the form of documents and presentations of each phase, as targets to be achieved before proceeding to the next phase. For the purposes of writing this paper, the authors will limit the artifacts to be displayed.

Automatic Weather Stations - Bagian 2


[Tulisan ini dibuat sebagai contoh Bahan Penelitian untuk Kerja Praktek Mahasiswa Teknik Elektro dan Teknik Informatika, Bagian Pertama dari Tulisan ini, dapat dibaca pada link dibawah ini:

Perangkat Authomatic Weather Stations - AWS 

Perangkat AWS
Secara umum perangkat atau komponen yang di butuh kan untuk membangun AWS di bagi menjadi beberapa bagian utama yaitu :
1. Sensor
Sensor digunakan pada AWS adalah jantung dan jiwa dari sistem. Oleh karena itu banyak perawatan harus dilakukan ketika memilih sensor yang tepat untuk kebutuhan pengguna.AWS standar Biro menggunakan sensor untuk memantau temperature, kelembaban, kecepatan angin dan arah, tekanan dan curah hujan. Sensor lanjutan lainnya yang tersedia untuk aplikasi khusus. Sensor ini dapat memantau ketinggian awan (ceilometer), visibilitas, cuaca saat ini, badai, suhu tanah (pada kisaran kedalaman) dan suhu terestrial. Biro ini juga menyelidiki jenis lain dari sistem seperti penguapan otomatis.
Ada beberapa karakteristik mendasar yang membentuk akurasi dan presisi dari sensor.
  • Resolusi - perubahan terkecil dapat mendeteksi perangkat (ini tidak sama dengan akurasi perangkat).
  • Pengulangan - kemampuan sensor untuk mengukur parameter lebih dari satu kali dan menghasilkan hasil yang sama dalam keadaan yang identik.
  • Response time - biasanya didefinisikan sebagai waktu yang dibutuhkan sensor untuk mengukur 63% dari perubahan.
  • Drift - kestabilan kalibrasi sensor dengan waktu.
  • Histeresis - kemampuan sensor untuk menghasilkan pengukuran yang sama apakah fenomena ini meningkatkan atau menurunkan.
  • Linearitas - penyimpangan sensor dari perilaku garis lurus yang ideal.

Beberapa jenis sensor yang terdapat pada Automatic Weather Station (AWS) antara lain adalah :
a. Sensor Arah Angin
Sensor ini berfungsi untuk mengukur arah angin dalam rentang ukurantara 0 - 360 derajat. Terdapat aneka merk dari beragam produsenbaik dari luar maupun dalam negeri.
b. Sensor Kecepatan Angin
Sensor ini mengukur kecepatan angin, biasanya menggunakan tiga buah piringan (cup) yang bergerak memutar tiang cup yang menghasilkan frekuensi berubah-ubah yang proporsional dengan kecepatan angin. 
c. Sensor Kelembaban Udara
Kelembaban Udara diukur menggunakan suatu sensor kapasitor tipis. Sinyal dari sensor kemudian diubah menjadi dua keluaran sinyal voltase.
d. Sensor Curah Hujan
Volume atau jumlah hujan yang jatuh diukur menggunakan sensor jenis Tipping Bucket. Di pasaran terdapat beragam merk Sensor Curah Hujan seperti Global Water, AllWeather, Vaisala, Casella dan lain-lain.
e. Sensor Radiasi Matahari
2. Data  Logger
Data logger adalah sebuah alat elektronik yang berfungsi mencatat data dari waktu ke waktu baik yang terintegrasi dengan sensor dan instrumen didalamnya maupun ekternal sensor dan instrumen.
Produk luar : CampbellSci, Seba, dll
Produk lokal : Smartdatalogger
3. Catu Daya
Catu Daya berasal dari battery dan solar panel yang berfingsi memberi tenaga kepada AWS agar bisa bekerja secara terus menerus.
4. Penangkal Petir
Berfungsi untuk menetralisir arus bertegangan tinggi dan mengamankan peralatan AWS baik sensor maupun peralatan lainnya.
Diantaranya : Kurn (Lokal), Neoflash, Leader (Prancis), Leitai (Cina)
5. Sistem Akuisisi Data
Merupakan sebuah sistem pengukuran penomena fisik atau listrik seperti tegangan, arus, temperatur dari sensor AWS oleh perangkat akuisisi data yang diteruskan ke komputer untuk diolah dan ditampilkan dalam bentuk tabel atau grafik.
6. Sistem Komunikasi Data
Terdiri dari modem komuniksi GSM (Global System for Mobile communication) 
dan Software Sistem maupun Software Aplikasi yang berfingsi menyimpan dan mengirim data pengamatan.
7. Sarana Penunjang
Berupa tiang, pagar,komputer untuk AWS portable biasa menggunakan trimpot yang bisa di pindah.   

Konfigurasi Perangkat AWS-IP
Sistem telemetri data AWS tersiri dari GPRS, SMS, dial up, dan RF. Dalam sistem telemetri GPRS dan dial up, layanannya memanfaatkan operator GSM komersial dan internet. Dengan demikian, pengguna memperoleh data secara real time dalam bentuk grafik dan data unduhan. Sistem telemetri SMS dimanfaatkan untuk pengiriman data periodik. Data ini dikirimkan sebagai peringatan dini kepada pengguna. Sementara itu, dengan sistem telemetri RF, pengiriman data AWS ke pengguna dilakukan dengan menggunakan frekuensi radio VHF/ UHF. Keuntungan telemetri RF ini adalah bebas biaya.

Automatic Weather Stations

[Tulisan ini dibuat sebagai contoh Bahan Penelitian untuk Kerja Praktek Mahasiswa Teknik Elektro dan Teknik Informatika]


Tinjauan Proses Bisnis
AWS (Automatic Weather Stations) merupakan suatu peralatan atau sistem terpadu yang di disain untuk pengumpulan data cuaca secara otomatis serta di proses agar pengamatan menjadi lebih mudah. AWS ini umumnya dilengkapi dengan sensor, RTU (Remote Terminal Unit), Komputer, unit LED Display dan bagian-bagian lainnya. Sensor-sensor yang digunakan meliputi sensor temperatur, arah dan kecepatan angin, kelembaban, presipitasi, tekanan udara, pyranometer, net radiometer. RTU (Remote Terminal Unit) terdiri atas data logger dan backup power, yang berfungsi sebagai terminal pengumpulan data cuaca dari sensor tersebut dan di transmisikan ke unit pengumpulan data pada komputer. Masing-masing parameter cuaca dapat ditampilkan melalui LED (Light Emiting Diode) Display, sehingga para pengguna dapat mengamati cuaca saat itu (present weather ) dengan mudah. (sebuah contoh AWS dapat dilihat pada Gambar dibawah)





Secara sederhana cara kerja dari AWS (Automatic Weather Stations) adalah mengumpulkan data pengamatan parameter cuaca secara otomatis melalui sensor-sensor secara berkala selanjutnya di kirim melalui jaringan GPRS(General Packet Radio Service) menggunakan layanan GSM (Global System for Mobile communication)  ke seluruh stasiun meteorology seluruh Indonesia. Seperti yang terlihat pada gambar di bawah ini:



Sistem pengelolaan data cuaca oleh AWS merupakan gabungan dari disiplin ilmu elektroteknik dan informatika. Hasil yang diberikan oleh AWS adalah informasi yang bermanfaat untuk penelitian terkait iklim dan cuaca, yang pada akhirnya bisa bermanfaat untuk kesejahteraan masyarakat. Proses bisnis pengelolaan data oleh AWS dapat dijadikan sumber acuan untuk penelitian mahasiswa yang melakukan Kerja Praktek ataupun Tugas Akhir.
