Abstract

Due to an application of coconut shell and cassava peel-based charcoal as an alternative material in carbon film resistors, the purpose of this study is to determine the value of both resistance and specific resistance of those materials. The fresh coconut shell and cassava peel were dried under sunlight prior to charcoal production through pyrolysis. The resulted charcoals were then grounded into powder and filtered. After that, the fine materials were inserted into a straw with a wide area of 6,07 x 10-7 m2and 1,2 x 10-4 m2 and the length of 0,03 m and 0,04 m. The results obtained that the resistance values of the coconut shell and cassava skin charcoal were 5  104 Ω to 11  104 Ω and 3  104Ω  to 5  104 Ω, respectively. While the specific resistance values of those charcoals were 1,133 Ωm to 2,34 × 102 Ωm and  0,758 Ωm to 1,28 102 Ωm, respectively. In conclusion, both resistance and specific resistance values of coconut shell charcoal seem to be relatively higher than the coconut shell charcoal.

Abstract

This study aims to compare the rate of heat absorption in black, red, green, yellow, milky white, and blue electrical light related to temperature change with a predetermined time variation. This study uses an AC power circuit to light a bulb with varied colours and then measures the temperature associated with the heat involved in the light on. The calculation in this study uses the Black principle concept. The results showed that black and green light bulbs had the greatest temperature change followed by red, blue, yellow, and white bulbs. This is in accordance with the basic concept that dark colours tend to conduct heat better than bright colours.

Abstract

The purpose of this research is to analyze the relationship between the intensity of light hitting the LDR to the resistance and the flame of the light. The research created an automatic lighting system, in which the lighting system was designed to turn on or off lights by light intensity. This research created automatic light controls using LDR light sensor. The LDR light sensor set is used as a switch that turns on or off a light automatically based on the recieved of intensity of light. By using the LDR components, it can design a series of light sensors for such items as outdoor light sensors, sleeping lights, garden lights, road lights that turn on at night and go out during the day automatically. The equipment used of the research were 2 test lamps, and done with 2 lighting sources, a natural source of lighting and an artificial source of lighting. From the research, it showed that the large light intensity affects the light flame by using LDR light sensor. It could be concluded that the greater of the light hitting intensity from the LDR surface was smaller than the value of the resistance and the flickering of the light. In contrast, the less light that affects the LDR, was the greater value of LDR resistance and lighter the light.

Abstract

Modifikasi pompa air bertenaga mesin telah dilakukan dengan memanfaatkan aliran air lemah. Tenaga penggerak pompa ini adalah kincir dengan rpm (putaran per menit) rendah.  Pompa ini terdiri atas delapan bagian utama, yaitu: rangka, kincir, gear besar, gear kecil, pompa jet, pipa masukkan, dan pipa keluaran. Pompa ini bekerja dengan mengkoversi aliran air debit rendah untuk memutar kincir yang tergandeng dengan gear besar. Selanjutnya, gear besar pada kincir juga berputar diikuti gear kecil pada pompa jet yang dihubungkan dengan rantai. Putaran gear kecil menggerakkan komponen pompa jet yang berputar untuk mengisap dan membuang air. Performa pompa ini dianalisis dengan mengukur debit pada ketinggian tertentu. Berdasarkan analisis yang telah dilakukan, maka diketahui bahwa pompa ini mampu mengangkat air sampai ketinggian 6  meter dengan debit air 0,02 liter per detik.

Abstract

Abstract Simulation of a spherical grain floating in fluid surface propagating sinusoidal wave is performed using molecular dynamics method by assuming that superposition of buoyant, gravitational, and viscous forces will make the grain to move in two-dimension. It is different than previous result, where the grain can only move in one-dimension since size of the grain Db << λf. In this work Db < λf so that direction of buoyant force must be considered. It is predicted theoretically that the two-dimensional motion tends to be a one-dimensional motion when Db/λ less than a certain value, but it remains as a two-dimensional motion when more than that value. In 20 s of observation frequency of the sinusoidal wave can determine whether the grain will move in the same direction of the travelling wave or not. Keywords: grains, simulation, buoyant force, gravitational force, viscous force.

Abstract

This study aims to categorise the clean and healthy lifestyles applied in Cot Sibati, Blang Krueng Village. The research subjects were ten 7 and 8 years-old children. The data collection method was descriptive qualitative, i.e. interview, observation and documentation. Given that only three out of eight indicators met the requirements, the results indicated that both clean and healthy living habit level was fairly poor. It could be concluded that these lifestyles have not been performed by the observed subjects that may be associated with the lack of information providing the importance of cleanliness and healthiness. Keywords: clean life behavior; healthy life behavior; clean life indicators; and healthy life indicators.

Abstract

Kajian kandungan kafein yang berkaitan dengan cita rasa kopi unik dari Aceh, kopi Khop, masih terbatas. Studi ini bertujuan untuk menentukan hubungan antara kadar kafein dalam bubuk kopi Khop dan karakteristik sensorik dengan analisis regresi linear. Bubuk kopi Khop dipisahkan berdasarkan empat kategori: halus (fine, F), sedang (medium, M), kasar (coarse, C), dan original (O). Keempat jenis bubuk kopi tersebut diseduh dengan air panas (90 oC) lalu diuji karakteristik sensoriknya menggunakan uji organoleptik meliputi rasa asam dan pahit, aroma, warna, dan residu ampas. Sampel kopi tersebut juga diukur kadar kafeinnya menggunakan spektrometer UV-vis dan harga pH-nya. Analisis dengan regresi linear sederhana menunjukkan hubungan linear negatif antara kadar kafein bubuk F, M, dan C dengan skor deskriptor sensorik kopi Khop. Berdasarkan hasil uji tersebut, kadar kafein bukan merupakan faktor tunggal yang menentukan hasil penilaian karakter sensorik bubuk kopi Khop yang ditunjukkan dengan linearitas negatif antara kadar kafein dan skor aroma kopi.

Abstract

Nutmeg seed shell waste contains 21.34% cellulose, 12.93% lignin, 53.67% crude fiber, 6.16% ash, 0.11% phenol, and 0.38% carbonyl. The content of cellulose and lignin in the nutmeg shell waste is quite large, so it can be used as something of value. Cellulose can be synthesized into cellulose acetate. The use of cellulose acetate is very diverse, such as in the film industry, biodegradable plastics, paper coatings, metals, and glass, as an adhesive for topographic films as the main raw material in membrane synthesis processes. Therefore, it is necessary to characterize cellulose and cellulose acetate from nutmeg shell waste (Myristica fragrance) in South Aceh. The method used is in the form of cellulose isolation using the soxhletation process, then bleaching and hydrolysis processes are carried out, then it is synthesized into cellulose acetate. Characterization of cellulose by determining % yield, cellulose content, ash content, moisture content, FTIR, XRD. Characterization of cellulose acetate by determining the acetyl content and FTIR. The characterization results obtained ash content of 3.04%, moisture content of 15.55%, yield of 35.36% and 5.29% cellulose content.
