Judul: Pengolahan Limbah Cair Rumah Sakit Kota Bogor secara Biologis
Abstrak: Hospital wastes from PMI Hospital and from other hospital in Bogor, as reference, using same waste treatment system, but with polyaluminium chloride addition as coagulant, were analyzed for several parameters: total suspended solids, pH, chemical oxygen demand, biochemical oxygen demand, ammonia, phosphate, and total coliform. All parameters had fulfilled the quality standard from Kep MLH No. 58/MNLH/12/1995, except the COD value for the third month, probably because excessive usage of detergent. Paired t-test to the waste parameters before and after treatment showed significantly different results. Therefore, the wastewater treatment in PMI Hospital has been effective, although still not as well as reference hospital.

Judul: Studi Potensi Pemanfaatan Limbah Cair Organik Rumah Sakit PMI Kota Bogor Sebagai Alternatif Energi Terbarukan (Biogas)
Abstrak: Waste is defined as all of the material that discarded from the human activities such as household, commerce, hospital, industrial, and agricultural. Biogas technology is one of technologies which can be used to convert hospital’s organic liquid waste to energy resource and other useful product such as liquid fertilizer. The objectives of this research is to determine the potential of hospital's organic liquid waste to produce biogas, and also to analyze the technical feasibility towards the implementation of biogas technology in processing of hospital's organic liquid waste. This research was divided into 2 steps: the preliminary study and the main study. In the preliminary study, raw material was analyzed (water content, C/N ratio) to find the best material and optimum composition which produce highest productivity. The selected material and composition will be use as feedstock for biogas producer plant which is observed in the main study. Result of preliminary study shows that the potential study was organic liquid waste without solids material (C/N ratio 16.36) which could produce biogas approximately 0.718 liters/day. The drum with capacity of 240 liters has been used as a continuous type digester. Result of technical analysis was indicated that the implementation of biogas technology to organic liquid waste without solid material, didn't feasible due to the low methane concentration (approximately 0.04%) in the biogas. The several factors which influenced biogas production were ambient temperature, C/N ratio, and toxic material.

Judul: Penerbangan Otomatis Pesawat Tanpa Awak Jenis Sayap Tetap dengan iNav
Abstrak: Pesawat tanpa awak (UAV) dapat dikendalikan secara manual dengan remote control atau secara otomatis dengan flight controller (FC). Salah satu jenis UAV adalah sayap tetap yang memiliki bentuk seperti pesawat terbang pada umumnya. Penelitian ini bertujuan untuk melakukan penerbangan otomatis pada UAV jenis sayap tetap dengan mengkonfigurasi perangkat FC. UAV yang digunakan adalah model SkySurfer X8 dengan bentang sayap 1.4 m. FC yang digunakan adalah Matek F405-Wing yang dikonfigurasi dengan perangkat lunak iNav. Berdasarkan hasil uji terbang, UAV berhasil terbang secara otomatis mengikuti skenario yang diberikan. Skenario terjauh berupa persegi berukuran 600×600 m pada ketinggian 100 m, yang ditempuh dalam waktu sekitar 2 menit dengan kecepatan sekitar 65 km/jam. Diharapkan prosedur perakitan, konfigurasi, operasi, dan hasil data uji terbang dapat menjadi acuan dalam penelitian selanjutnya.
