Abstract

Shiping components necessary are needed nowadays. For that many minor industry develop. One of them is CV. Setia Kawan Tegal City which is one of central metal cast company which main product is ship component but product that produced by CV. Setia Kawan has not comply but JIS or SNI standart. Based on that, this final project purposed to now tensil test and material composition include from the material that produced by CV. Setia Kawan. Materials which used is pure elbow Aluminium, Aluminium Plat, brake Canvas and used pan. Those materials must pass some process before tested, melting process, casting process than extracting from mould with use permanent mould. After that the next process which done is tensil test. Beside tensil test material also pass material composition test. Tensil test result shows that Aluminium and Break canvas has the best materials quallity and fullfell JIS and SNI standart about 13,18 kg/mm² for Aluminium Plate with used pan fusion about 10,46 kg/mm². Where as for elbow Aluminium and Aluminium Plate fot it about 8,84 kg/mm² and 10,33 kg/mm². For the materials composition test result with passed melting process, elbow aluminium and brake canvas and Aluminium Plate with used plan have fullfelled standart both JIS and SNI which each content about 92,46% and 99,43%. For elbow Aluminium and Aluminium Plate each content about 99,43% and 98,46% but material give not pass standart.

Abstract

Dalam pembuatan/ pengolahan makanan berkuah, kondisi koagulasi santan yang tidak stabil harus dihindari karena mengurangi cita rasa makanan. Penentuan titik koagulasi santan terkait dengan lama waktu pemanasan menjadi penting. Pada penelitian ini diteliti titik waktu optimal santan terkoagulasi secara maksimal melalui pengukuran parameter warna, kekentalan, dan endapan. Bahan yang dipergunakan : santan kelapa kemasan (Cocos nucifera). Alat yang dipergunakan: waterbath, viscometer/ alat pengukur viskositas, alat ukur volume/ gelas ukur, vacuum filter atau pressure filter. Pemanasan santan dilakukan pada suhu 100°C dengan variasi waktu: 0, 1, 2, dan 3 jam. Metode pengukuran koagulasi santan menggunakan metode filtrasi Charm. Hasil penelitian menunjukkan perlakuan pemanasan terhadap santan pada suhu 100°C dengan waktu pemanasan berbeda memberi dampak berbeda pada aspek warna santan. Nilai lightness (L) santan kontrol (pemanasan 0 jam) berkisar 92,7, sedangkan santan yang mengalami perlakuan pemanasan nilai lightnessnya berkisar 75 - 71. Nilai viskositas santan pada perlakuan pemanasan 100°C selama waktu 2 jam mencapai titik tertinggi yaitu 0,8 N.s/m2. Titik optimal koagulasi santan diperoleh pada waktu perlakuan pemanasan santan 2 jam. Kata kunci : santan, koagulasi, filtrasi

Abstract

Abstrak Pengembangan penelitian roket di Indonesia sedikit demi sedikit telah menunjukkan hasil yang cukup memuaskan Dengan perkembangan teknologi roket yang cukup dewasa ini, juga tidak ketinggalan dalam bidang militer dimana roket digunakan sebagai media penghantar bahan peledak kepada sasaran yang dituju dengan daya hancur yang hebat.. Masalah yang paling mendasar dalam roket adalah tentang kestabilan terbang roket tersebut. Untuk mengatasi permasalahan tersebut digunakan sensor accelerometer dan giroskop. Dengan merancang sensor accelerometer dan giroskop sebagai penyetabil gerakan serta di hubungkan dengan motor servo mg90s sebagai penggerak sirip roket. Di tambah dengan kontrol PID agar respon gerakannya bagus. Metode pengujiannya dengan diuji menggunakan beban statis dan beban dinamis sampai di dapatkan hasil berupa kehandalan sirip terhadap beban yang diberikan .  Kata kunci: accelerometer, giroskop, mg90s, PID, beban.

Abstract

Perkembangan teknologi di dalam suatu negara adalah sebuah kunci untuk bangkit dalam dunia yang semakin modern. Apabila suatu negara berhasil menciptakan dan mengembangkan suatu teknologi yang canggih untuk menjaga kedaulatan negara maka negara tersebut akan langsung diperhitungkan atau disegani oleh negara lain. Maka teknologi akan terus di angkat oleh negara tersebut agar semakin canggih dan bisa bersaing dengan alutsista negara lain.BT (Basis Tempur) adalah batu loncatan sebagai kedudukan sementara pasukan kita yang lepas dari induknya untuk melaksanakan operasi di daerah musuh (ke dalam daerah musuh). Basis tempur selalu berada di daerah tempur. Dalam patroli daerah ini di sebut daerah penyelaman. Dimana dalam melaksanakan sistem pengamanan khususnya pada malam hari masih terbatas hanya dengan pengamatan visual mata saja, yang dimana pengamatan manusia pada malam hari terbatas karena tidak adannya cahaya. Dengan memanfaatkan gelombang ultrasonik dan gelombang infra red yang dihasilkan oleh sensor ultrasonik dan sensor pir dan dengan menggunakan metode fuzzy logic control sehingga dapat diperoleh hasil deteksi manusia yang tertampil pada lcd sehingga manusia yang akan masuk basis tempur dapat terdeteksi sehingga dapat diambil keputusan secepatnya yang merupakan suatu keuntungan dalam peperangan. Hasil derajad dan ploting pada lcd menggunakan fuzzy logic control dalam pengolahan datanya
