Abstract

Abstrak Ketika suatu pesawat terbang mengalami kecelakaan terjatuh ke dalam air, maka lokasi keberadaannya dapat dideteksi oleh alat yang disebut receiver beacon black box locator acoustic (pingers receiver). Pingers receiver berfungsi untuk menerima sinyal dengan frekuensi 37,5 kHz ± 1 kHz dari pingers transmitter atau Underwater Locator Beacon (ULB) yang berada pada black box pesawat. Dalam penelitian ini dibuat perancangan pingers receiver yang tersusun dari rangkaian Band Pass Filter (BPF), detektor selubung, penguat audio, dan loud speaker. Frekuensi sinyal 37,5 kHz ± 1 kHz yang dikirim oleh pingers transmitter akan diterima oleh pingers receiver, dimana tahap pertama melewati rangkaian Band Pass Filter (BPF) selanjutnya sinyal akan dideteksi oleh detektor selubung untuk mengambil kembali sinyal informasi yang berupa sinyal pulsa dengan lebar pulsa 10 milidetik dan interval 1 detik sebagai sinyal pingers yang nantinya mampu didengar oleh telinga manusia. Berdasarkan perancangan yang telah dibuat, output sinyal yang dihasilkan oleh prototipe pingers receiver tersebut memiliki lebar pulsa 14 milidetik dengan interval 1 detik. Kata kunci: pingers receiver, band pass filter (BPF), detektor selubung, loud speaker. Abstract When an aircraft caught in an accident and crashes into the water, its location can be detected using a device called a receiver beacon black box locator acoustic (pingers receiver). The pingers receiver functioned as a reciever signal with 37,5 kHz ± 1 kHz frequency from trnasmitter pingers or Underwater Locator Beacon (ULB) which is on air plane black blox. In this research made design pingers receiver composed of a series of  Band Pass Filter (BPF), envelope detector, audio amplifier, and loud speaker. The signal of 37,5 kHz ± 1 kHz  frequency sent by pingers transmitter will bereceived by pingers receiver, after which the signal will be processed by the Band Pass Filter (BPF) circuit before being detected by envelope detector for take back the signal information which like pulse signal with 10ms width and 1 second interval as pingers signal tha can  be to  be heard by human ear. Based on the  design that  was made, the signal ouput generated by the prototype has a 14 ms width with 1 second interval. Keywords: pingers receiver, band pass filter (BPF), envelope detector, loud speaker.

Abstract

More than half of the waste produced at IPB University is organic waste and is routinely generated every day. The waste could have economic value if it has proper management. On the other hand, waste management costs money for investment and operation. Therefore, a proper project plan is needed so the management can generate profits. This research aims to (1) estimate the potential of organic waste from IPB University that can be used optimally to produce economic value and (2) analyze the economic feasibility of organic waste at IPB University. The result of this research shows that the number of potential organic waste from IPB University that can give economic value is 506,496 kg each year. Economic value and feasibility were analyzed using three criteria, which are Net Present Value (NPV), Internal Rate of Return (IRR), and Net Benefit Cost Ratio (Net B/C). In economic analysis with a project life cycle of 20 years, the organic waste management obtained an NPV value of 915,056,415 rupiahs, 1.29 for Net B/C, and 10.35% for IRR. In financial analysis with a project life cycle of 20 years, the organic waste management obtained NPV value by -695,114,013 rupiahs, 0.78 for Net B/C, and 0.12%for IRR. Based on the description above, it can be concluded that the project IPB campus organic waste management is economically feasible but not feasible financially.

Abstract

Penelitian ini membahas tentang analisis budaya organisasi PT XYZ pascamerger. PT XYZ terbentuk dari tiga perusahaan yaitu PT X, PT Y, dan PT Z. Tergabungnya tiga perusahaan tersebut, membentuk berbagai tantangan dalam menciptakan budaya organisasi yang positif. Dalam menganalisis permasalahan ini, peneliti menggunakan teori budaya organisasi untuk melihat bagiamana upaya PT XYZ dalam membentuk budaya perusahaan, serta apa saja faktor pendukung dan penghambat dalam menciptakan budaya organisasi. Penelitian ini menggunakan metode kualitatif dengan pendakatan deskriptif. Hasil penelitian menunjukan bahwa PT XYZ hanya dapat memenuhi dua asas yang terdapat dalam budaya organisasi yang positif, yaitu asas empiris dan asas prestasi. Sedangkan, enam asas lainnya, asas tujuan, asas keunggulan, asas konsesus, asas kesatuan, asas keakraban, dan asas integritas tidak cukup kuat di dalam budaya organisasi PT XYZ pascamerger. Penelitian ini merupakan bagian dari tesis peneliti yang tidak dipublikasikan.
