Abstract

Coastal erosion in Sayung Distric, Demak Regency submerged 300 hectares of brackish water ponds.  However, after the local government management by soft  and hard barriers construction  resulting the formation of semi-closed coastal water area with the depth of 1 – 7 m in depth.  The condition of the this  eroded coastal water is physically degraded, idle and abandont.  The aims of this research were to evaluate ecological condition of the eroded coastal  water at Sayung for coastal aquaculture based on its Trophic Saprobic Index  values.  The research was carried out from September 2009- August 2010. The results show that the eroded coastal water at Morosari, Sayung District Demak Central Java is lightly to moderately polluted, however, ecol[ogically it is still suitable for coastal aquaculture activity, especially for cultured organisms which are at the lowest level of the food chain/the plankton feeder .

Abstract

Abstract--A manual door security system that has many shortcomings including difficulty opening locks when used, easily broken and keys that tend to be duplicated thereby reducing convenience and security. To prevent this, a good and easy-to-use room security system is needed. At this time began to develop an electronic room safety system using RFID technology (Radio-Frequency Identification) to improve the security system at the door of the house. In this study discusses the design and prototype of an automatic room door lock using an RFID system. The research method used is research and development. This Automatic Door is programmed by the Arduino application by creating a security system using Radio Frequency Identification (RFID) as a radio wave of data carrier frequencies that will be received by the receiver. The results of this study are the creation of an automatic home door security system using RFID which has a better level of security compared to manual security, so that it can cope with acts of theft in homes that are often abandoned by residents. In addition, the use of RFID can also minimize the overall lock on the house, so that every family member needs only one tag card / key to open all the locks on the door in the house. Keywords: Arduino Uno, RFID, Servo Motor, Solenoi Abstrak--Sistem pengamanan pintu rumah yang bersifat manual memiliki banyak kekurangan diantaranya sulit membuka kunci ketika digunakan, mudah dibobol dan kunci yang cenderung dapat diduplikat sehingga mengurangi kemudahan dan keamanan. Untuk mencegah hal tersebut dibutuhkan sistem keamanan ruangan yang baik dan mudah digunakan. Saat ini mulai dikembangkan sistem pengaman ruangan yang bersifat elektronik dengan menggunakan teknologi RFID (Radio-Frequency Identification) untuk meningkatkan sistem keamanan pada pintu rumah. Dalam penelitian ini membahas mengenai desain dan prototype pengunci pintu ruangan otomatis menggunakan sistem RFID. Metode penelitian yang digunakan adalah riset dan pengembangan. Pintu Otomatis ini diprogram oleh aplikasi Arduino dengan membuat sistem keamanan menggunakan Radio Frequency Identification (RFID) sebagai gelombang radio frekuensi pembawa data yang akan diterima receiver. Hasil dari penelitian ini adalah terciptanya sistem keamanan pintu rumah otomatis menggunakan RFID yang memiliki tingkat keamanan lebih baik dibandingkan dengan pengamanan manual, sehingga dapat menanggulangi terjadinya tindak pencurian pada rumah-rumah yang sering ditinggalkan oleh penghuninya. Selain itu penggunaan RFID ini juga dapat meminimalis keseluruan kunci pada rumah, sehingga setiap anggota keluarga cukup membutuhkan satu tag card / kunci untuk membuka seluruh kunci pada pintu yang ada di rumah.

Abstract

Dusun Gerupuk merupakan dusun yang terletak pada sisi barat Teluk Gerupuk. Mayoritas penduduk di Dusun Gerupuk bekerja sebagai nelayan, baik nelayan tangkap maupun nelayan budidaya. Hasil tangkap ikan nelayan umumnya didistribusikan ke pedagang kecil. Namun, waktu simpan ikan sangat pendek sehingga harus ada inovasi yang dapat memperpanjang waktu simpan ikan tersebut. salah satunya yaitu dengan membuat inovasi produk olahan berupa Abon Ikan. Karena minimnya pengetahuan masyarakat Gerupuk mengenai pengolahan ikan segar menjadi abon, sehingga diadakan pelatihan pembuatan abon ikan di Dusun Gerupuk tujuan dilakukannya kegiatan ini yaitu untuk meningkatkan motivasi masyarakat terutama ibu-ibu dalam mengolah ikan serta dapat memperpanjang waktu simpan dan meningkatkan nilai ekonomi dari ikan. Metode yang digunakan yaitu FGD (Focus Group Discussion). Persiapan uji coba produksi, kegiatan pelatihan, serta monitoring dan evaluasi. Hasil dari kegiatan pelatihan ini yaitu sebuah produk berupa abon ikan serta terbentuknya kelompok usaha yang berjumlah 4 orang. Diharapkan setelah kegiatan ini usaha abon ikan akan terus berjalan dan produk abon ikan bisa menjadi produk oleh oleh Khas Dusun Gerupuk.
