ANALISA PENGARUH PERSENTASE CAMPURAN JARAK PAGAR (JATROPHA CURCAS) DAN KAPOK (CEIBA PETANDRA) BIODIESEL TERHADAP PERUBAHAN SIFAT BAHAN BAKAR
No full textTo increase the production of biodiesel from non-edible vegetable oils, it is one of the effective ways to solve the limited number of traditional raw materials and the high prices of these raw materials. The primary objective of this study was to optimize the production of biodiesel derived from non-edible raw materials, namely J. curcas and C. Pentandra. The production process is carried out through the esterification and transesterification process of the mixture of J. curcas and C. Pentandra oils. The results of the study indicate a change in biodiesel properties due to the mixing of raw materials. But overall, the mixture of J. curcas and C. Pentandra oils have characteristic features that are suitable and meet the requirements given in the D6751 ASTM and EN 14214 standards.

In analyzing the function of Didong-didong, the author applies the theory of 10 musical functions introduced by Alan P. Merriam. And to analyze the form of the ceremony, the author uses the theory of traditional ceremonies pioneered by Koentjaraningrat, which has several elements such as: the place where the ceremony takes place, the time the ceremony is held, the objects and equipment of the ceremony, and the people involved in the ceremony. The results of this research show that during the Nambalken Gelar ceremony there was a Didong-didong song sung by Perkolong-kolong. This song contains messages, hopes and prayers for the child whose name is written. The melody form in this song is the same but the verses are different. The conclusion obtained from this research is that Didong-didong is a song among the Karo people in Langkat which must be sung during the Nambalken Gelar ceremony in Langkat Regency.95 PagesSkripsi Sarjan
Sistem Otomasi Dispenser Menggunakan Sensor Ultrasonik Berbasis Atmega32
No full textWater dispenser technology continues to evolve. However, the user of water dispenser must expend energy to suppress the tap. And also must remain focused so that water being poured into the cup dispenser does not overflow. With this basis, the author tries to make it easy for users. Namely by automate the water dispenser on the dispenser faucet water. Users simply place the cup and determine the volume of water to be filled into the cup, then the water will automatically come out of the faucet. Then when the water volume that is loaded has reached a certain point, the pump will automatically turn off. In this automatic water dispenser, the microcontroller is used as the main component in the control system. While the automatic water dispenser uses an ultrasonic sensor to detect the presence of the cup and potentiometer to measure the volume of the cup.Teknologi dispenser air terus berkembang. Namun, pengguna dispenser air harus mengeluarkan energi untuk menekan keran. Dan juga harus tetap memusatkan perhatiannya agar air yang dikucurkan dispenser ke dalam cangkir tidak melimpah. Dengan dasar inilah, penulis mencoba memberikan kemudahan bagi pengguna dispenser air dengan melakukan otomatisasi pada keran dispenser air. Pengguna cukup meletakkan cangkir dan menentukan volume air yang akan diisi ke dalam gelas, kemudian air akan secara otomatis keluar dari kran. Kemudian ketika volume air yang diisi telah mencapai titik tertentu , maka pompa akan otomatis mati. Pada dispenser air otomatis ini, mikrokontroler digunakan sebagai komponen utama dalam sistem pengendali. Sementara itu dispenser air otomatis ini menggunakan sensor ultrasonik untuk mendeteksi adanya cangkir dan potensiometer untuk mengukur volume cangkir tersebut.80 HalamanKertas Karya Diplom
