ABSTRAK
Telepon Seluler (ponsel) telah berubah dari alat telekomunikasi biasa menjadi alat yang mempunyai berbagai fasilitas. Selain untuk berkomunikasi, ponsel juga dapat digunakan untuk koneksi internet (lewat fasilitas GPRS) dan pengiriman gambar (lewat fasilitas MMS). Dengan menggunakan MMS dan GPRS, segala sesuatu dapat diakses tanpa mengenal batas waktu dan tempat.
Salah satu kegunaan dari pemakaian MMS dan GPRS adalah penggunaan kedua fasilitas tersebut untuk memantau keamanan rumah karena keamanan rumah adalah sesuatu yang sangat berguna bagi setiap pemilik rumah.
Pada tugas akhir ini dibahas tentang cara merancang dan membuat suatu sistem pemantau keamanan rumah dengan menggunakan MMS.
Sistem pemantau keamanan rumah akan menggunakan webcam yang dapat mengambil gambar secara otomatis jika mendeteksi suatu perubahan gambar dan mengirimkannya melalui MMS lewat jaringan GPRS dengan menggunakan sebuah modem GPRS. Sistem keamanan rumah dibuat dengan menggunakan visual basic 6 dan program MMS Composer.
Berdasarkan hasil pengujian sistem, diketahui bahwa terdapat permasalahan pada bagian pengiriman MMS. MMS yang dikirim tidak dapat diterima oleh MMSC operator sehingga gambar yang diambil webcam tidak dapat diterima oleh ponsel. Gambar kemudian akan dikirim ke sebuah PC yang pada aplikasi selanjutnya PC tersebut adalah server di kantor kepolisian. Pada pengujian pengiriman gambar PC ke PC diketahui bahwa tingkat keberhasilan pengiriman hanya 36,6%. Hal ini disebabkan karena kualitas layanan GPRS di daerah tempat sistem ini diuji masih kurang baik.
ABSTRACT
Cellular Phone (Cellphone) has changed from an ordinary telecommunication device into a multi-facilities device. Besides working as a communication device, a cellphone can also be used as an internet connection (via GPRS) and picture sender (via MMS). Using MMS and GPRS, anything can be access in regardless by limit of time and place.
One of the useful in using MMS and GPRS is an using the both facilities to monitor the security of home because the security of home is a something that it has useful for every home owners.
In this final project discusses about how to design and realization of home security survailance system using MMS.
The home security survailance system will use a webcam that it can take a picture in automatically when there is detection for a change of picture and send the picture through MMS via GPRS network with use a GPRS modem. Home security system constructed with using a visual basic 6 and MMS Composer program.

BAB I
PENDAHULUAN
1.1 Latar Belakang
Keamanan rumah adalah sesuatu yang sangat berharga bagi setiap orang. Banyaknya pencurian akhir-akhir ini, yang melibatkan pembantu rumah tangga atau satpam penunggu rumah, membuat banyak orang berpikir untuk membiarkan rumah mereka kosong daripada menyuruh orang lain sebagai penunggu rumah. Hal ini tentu juga akan mempunyai resiko yang cukup besar karena pencuri akan lebih mudah memasuki rumah yang kosong tersebut. Hal ini membuat banyak orang dihadapkan pada suatu pilihan yang dilematis apabila harus meninggalkan rumah untuk keperluan tertentu. Untuk menanggulangi permasalahan keamanan tersebut, setiap pemilik rumah memerlukan alat yang dapat memantau keamanan rumah dari jarak yang jauh.
Salah satu alternatif yang kini dikembangkan adalah sistem pemantau rumah jarak jauh melalui Short Message Service (SMS). Namun hal ini belum banyak memberikan solusi karena SMS tidak memberikan gambaran keadaan rumah yang sebenarnya. Alternatif lainnya adalah dengan melalui Multimedia Messaging Service (MMS). MMS merupakan jasa layanan pesan multimedia yang
dapat mengirimkan pesan secara multimedia melalui ponsel. Pemilik rumah akan dapat mengetahui keadaan rumah melalui pesan MMS pada ponsel. Untuk keperluan tersebut, penelitian tugas akhir ini membahas tentang “Sistem pemantau keamanan rumah dengan menggunakan MMS”.
1.2 Identifikasi Masalah
Dari latar belakang tersebut, maka masalah dalam Tugas Akhir ini dapat dirumuskan sebagai berikut :
2
1.3 Tujuan
Tujuan penyusunan tugas akhir ini adalah merancang dan membuat sistem pemantau keamanan rumah dengan menggunakan MMS.
1.4 Pembatasan Masalah
Didalam membuat suatu sistem pemantau keamanan rumah dengan menggunakan MMS ini terdapat beberapa persoalan. Agar permasalahannya menjadi jelas, tugas akhir ini memerlukan pembatasan-pembatasan sebagai berikut:
1. Dalam satu rumah hanya terdapat 1 kamera.
2. Sistem pengiriman data menggunakan MMS dan GPRS pada jaringan GSM.
3. Proses mendeteksi gambar dan menangkap gambar menggunakan pemrograman visual basic pada PC.
1.5 Sistematika Laporan
Untuk mendapatkan gambaran yang jelas dan lengkap tentang masalah yang akan dibahas, maka penulisan Tugas Akhir ini dibagi menjadi 5 bab dengan sistematika sebagai berikut :
1. BAB I PENDAHULUAN
Bab ini akan menjelaskan mengenai apa saja yang melatarbelakangi penulisan laporan tugas akhir, mengidentifikasi masalah yang akan diselesaikan dalam tugas akhir dan apa saja yang menjadi tujuan penyusunan laporan tugas akhir, pembatasan masalah sehingga ruang lingkup permasalahan yang akan diselesaikan menjadi lebih fokus, dan sistematika penulisan laporan tugas akhir ini.
2. BAB II DASAR TEORI
3
3. BAB III PERANCANGAN SISTEM DAN REALISASI
Pada bab ini akan dibahas mengenai perancangan tiap-tiap bagian dari sistem pemantau keamanan dengan MMS yang akan dibuat.
4. BAB IV PENGUJIAN ALAT DAN ANALISA
Bab ini akan menampilkan dan menganalisa hasil pengujian terhadap sistem pemantau keamanan dengan MMS yang telah dibuat.
5. BAB V KESIMPULAN DAN SARAN
BAB V
KESIMPULAN DAN SARAN
5.1 Kesimpulan
• Sistem pemantau keamanan rumah dapat bekerja dengan baik namun pengiriman gambar melalui MMS belum dapat dilakukan karena adanya hambatan pada MMSC operator yang menolak pesan MMS dari aplikasi di luar jaringan MMS operator.
• Sistem pemantau keamanan rumah dapat bekerja dengan cara mengirimkan gambar keamanan rumah ke server tertentu melalui jaringan GPRS.
• Tingkat keberhasilan pengiriman gambar server to server sangat dipengaruhi oleh besar file gambar yang dikirimkan.
• Tingkat keberhasilan pengiriman gambar yang hanya 36,6% dikarenakan kualitas jaringan GPRS di daerah tempat pengujian sistem masih kurang baik.
5.2 Saran
• Operator GSM dapat mempergunakan sistem pemantau keamanan rumah melalui MMS dan GPRS untuk meningkatkan pemakaian layanan MMS dan GPRS di Indonesia.
