Abstract

Abstrak - Unggas domestik di sekitar kawasan Cagar Alam Pulau Dua (CAPD) banyak berinteraksi dengan burung air liar yang terinfeksi virus H5N1. Oleh karena itu perlu diperoleh informasi terkait keberadaan Virus AI pada unggas domestik tersebut. Penelitian ini bertujuan untuk mengetahui prevalensi serologi Avian Influenza (AI) H5N1 pada unggas peliharaan masyarakat yang dipelihara dengan sistem backyard di sekitar kawasan CAPD. Pengamatan terhadap habitat dan perilaku bebek, ayam dan mentok dilakukan untuk menganalisa adanya interaksi dengan burung air liar di kawasan CAPD. Sebanyak 49 sampel serum yang terdiri dari 15 sampel serum bebek, 14 sampel serum mentok dan 20 serum ayam diperiksa keberadaan antibodi terhadap AI subtipe H5N1 melalui uji hambatan aglutinasi (Haemaglutination Inhibition). Hasil pengamatan menunjukkan presentase seroprevalensi mencapai 100% dengan nilai Geometric Mean Titer sampel yang diperiksa sebesar 27,9 untuk mentok, 24,6 untuk bebek dan 277 untuk ayam. Terdapatnya antibodi membuktikan unggas peliharaan masyarakat di kawasan CAPD pernah terpapar virus AI subtipe H5N1. Kata Kunci - Avian Influenza, CAPD, Unggas Domestik, Haemaglutination Inhibition Abstract - Domestic birds around Pulau Dua Nature Reserve area (CAPD) interact with wild water birds infected with H5N1 virus. Therefore it is necessary to obtain information related to the presence of AI virus in domestic poultry. This study aims to determine the prevalence of Avian Influenza serology (AI) H5N1 in community poultry maintained by backyard system around CAPD area. Observation of habitat and duck, chicken and stuck behavior was done to analyze the interaction with wild water birds in CAPD area. A total of 49 serum samples consisting of 15 serum duck samples, 14 serum serum samples and 20 serum chickens examined the presence of antibodies against AI subtypes H5N1 through an agglutination inhibition test (Haemaglutination Inhibition). The observation result shows that seroprevalency percentage reaches 100% with Geometric Mean Titer value of examined sample is 27,9 for stool, 24,6 for duck and 277 for chicken. The presence of antibodies proves that community poultry in the CAPD region has been exposed to AI virus subtype H5N1. Keywords - Avian Influenza, CAPD, Unggas Domestik, Haemaglutination Inhibition

Abstract

Abstrak  - Indonesia perlu mempersiapkan masyarakatnya agar tidak terus menerus menjadi konsumen namun menjadi produsen yang bisa bersaing di pasar global. Oleh karena itu, kami mencoba menjawab permasalahan tersebut dengan merangkul para pelajar SMA/SMK dan sederajat agar menyadari betapa pentingnya mempelajari teknologi sedari dini. Langkah awal yang dapat dilakukan adalah melalui pelatihan dasar flip-flop. Pelatihan ini sebagai modal awal membangun sifat kritis terhadap teknologi. Jika kepedulian telah terwujud diharapkan akan membawa perubahan untuk kemajuan IPTEK di Indonesia. Flip flop pada pelatihan ini adalah rangkaian lampu yang dapat menyala secara bergantian atau kedap kedip seperti layaknya lampu hias sehingga bisa memberikan nilai keindahan pada area disekelilingnya. Cara pembuatan rangkaian lampu flip flop ini sangatlah mudah. Namun dibutuhkan ketelitian dan juga ketekunan dalam membuatnya. Kata Kunci – Teknologi, Flip-Flop, Lampu Hias, Seven Segmen Abstract - Indonesia needs to prepare its society not to continue to be a consumer but a producer that can compete in global market. Therefore, we try to answer the problem by embracing the students of Senior High School / Vocational High School and equal to realize how important to learn technology early on. The first step that can be done is through basic flip-flop training. This training as an initial capital builds a critical nature of technology. If the concern has been realized it is expected to bring changes to the progress of science and technology in Indonesia. Flip flop in this training is a series of lights that can be alternated or alternatively blinking like an ornamental light so that it can give a beauty value in the area around. How to manufacture this flip flop light circuit is very easy. But it takes precision and also diligence in making it.  Keyword – Technology, Flip – Flop, Decorative Lights, Seven Segmen

Abstract

Abstract – Hydraulics machines are important parts in semi solid metal forging machine, to form the workpiece by pressing. Semi-solid machine positioning movements are required to have a high accuration, to get the high accuracy of the movement system a servo hydraulic control is added ,which consist of servo valve and digital controller (Aerotech A3200). The digital control parameters (kpos, kp, ki) are used to enhanced the hydraulic movement. To get the effect of the control parameters of the plant (hydraulic servo), a mathematical approach is used for simulation in matlab. In this research, study was done by optimize kp and ki parameters of the control system. Prior to the optimization, simulation was conducted using matlab. Where the simulated testing is using the input unit (step) and frequency (bode) to predict the circumstances that occurred to the plan which is then compared with experimental results. a step response was simulated in matlab to analyze the error of the hydraulic system. Having obtained the minimum error from adjusting kp and ki in matlab, a trend graphic error was used as a guideline to adjust parameter in actual system. The last step is to implement and adjust kp/ki in actual system and measure the real position error.Based on this research, it concluded that the error before adjustment are 0.6118-1.2642 mm for autotune  parameter kp 3500000, ki 50000. The result of average error in this experiments after adjustment are 0.017-0.166 mm for parameter kp 250000, ki 10000. Keywords - Hydraulic Servo, Aerotech A3200, Step response, Bode plot, Semi-Solid Machine.

Abstract

Abstrak - Manusia pada dasarnya adalah mahkluk sosial, menjalin sebuah komunikasi yang baik menjadi hal penting dan mutlak dalam membangun sebuah ranah dan komunitas sosial yang baik. Manusia juga merupakan makhluk yang berkelompok sehingga didalam tatanan masyarakat dalam sebuah perkumpulan haruslah terdapat seorang pemimpin dalam kelompok tersebut. Adanya seorang pemimpin menjadikan terciptanya struktur dan rangka kehidupan yang jelas sehingga keberlangsungan kehidupan dapat berjalan dengan baik. Perhitungan suara cepat (Quick Count); atau dikenal sebagai tabulasi suara parallel (Parallel Vote Tabulation) merupakan salah satu metode yang berguna untuk memantau pada hari pemungutan suara. Pada dasarnya Quick Count ini adalah sebuah proses pengumpulan  informasi oleh relawan melalui pemantauan langsung pada saat pemungutan suara dan penghitungan suara di Tempat Pemungutan Suara (TPS) yang sudah ditentukan. Sehingga Quick Count adalah proses perhitungan hasil suara berdasarkan sampel yang dikirim relawan kepada server pusat di TPS yang sudah ditentukan bukan total hasil tabulasi yang dilakukan resmi oleh Komisi Pemilihan Umum (KPU). Kata Kunci - Quick Count, Komisi Pemilihan Umum, Tempat Pemungutan Suara. Abstract - Humans are basically social beings, establishing a good communication becomes an important and absolute in building a good domain and social community. Human being is also a group that in the society in a gathering there must be a leader in the group. The existence of a leader makes the creation of structure and order of life is clear so that the survival of life can run well. Quick Count; otherwise known as parallel voting tabulation (Parallel Vote Tabulation) is one useful method to monitor on voting day. Quick Count Basically this is a process of gathering information by volunteers through direct monitoring during voting and counting at polling stations (TPS) that have been determined. So the Quick Count is the process of calculating the result of the vote based on the sample sent by the volunteer to the central server at the specified TPS, not the total tabulation result done by the General Election Commission (KPU). Keywords – Quick Count, General Election Commission, Polling Stations
