and cutter, supervised by ACHWIL PUTRA MUNIR and AINUN ROHANAH
Until this time, peeling of pineapple fruit is known only through manual
tools by kitchen knife. However, later on pineapple peeler has begun to be
developed in the form of pineapple peeler manually press by using human
operator. Therefore through this research design, the author tried to ease the
peeling of pineapple peel by designing a pineapple peeler equipment which had a
larger capacity which to be more effective and efficient in pineapple peeling. This
principle of the manual pineapple peeler and cutting was worked by moving the
blades to the pineapple after cutted both of its end, then the cutted pineapple was
place parallel on the pedestal tools with the bladesdirection move by
manuallypressed. The capacity of the pineapple peeler was 139,86 kg/hour,
147,71 kg/hour and 152,67 kg/hour.69 HalamanSkripsi Sarjan

Irrigation efficiency on trickle irrigation system is higher than others, but it can only be applied by the rich farmers who have big finance, due to high investation for infrastructure, irrigation systems, and equipment. Effective and efficient water utilization are very important in plants cultivation in dry area to fulfill water requirement. Drip irrigation is considered as one of the alternative in fulfilling water requirement in correct time, volume and quality. The parameter used were water content, wetted area value, irrigation uniformity, and efficiency. The results showed that wetted area value was 0,075 m, irrigation uniformity was 92,54 %, and irrigation efficiency was 96,95%.59 HalamanSkripsi Sarjan

supervised by AINUN ROHANAH, dan SULASTRI PANGGABEAN
The dependence of people consume rice is not followed by the increase of
rice production. Therefore on, alternative foodstuffs is needed such as cassava
which can be processed into gaplek, and cassava flour. This research was done in
Agriculture Engineering Laboratory Faculty of Agriculture, and Food Science
and Technology Laboratory Faculty of Agriculture in Oktober 2014 until March
2015 using non factorial completely design with tray holes diameter of (D1) 3
mm, (D2) 5 mm, and (D3) 7 mm. The parameters analysed were processing
capacity, moisture content, yield, and brightness level. The results, showed that,
the best drying cassava is produced by (D2) 5 mm63 HalamanSkripsi Sarjan

SAIPUL BAHRI DAULAY and AINUN ROHANAH.
One of process to find the machine velocity in processing of paper to
become pulp is by testing its pulley diameter. This study was aimed to
determine the effect of pulley diameter of pulp maker machine. The parameters
measured were the effective capacity of machine, yield, and the percentage of
loose material. This research was conducted from June to August 2016 at
Agricultural Engineering Laboratory Agricultural Faculty University of
Sumatera Utara,Medan. Non factorial randomized block design was used in this
research.
The results showed that pulley diameter affect the observed parameters.
Effective capacity were 53,33 kg/hour, 50,77 kg/hour, and 49,01 kg/hour with
pulp yield were 94%, 91%, a59 HalamanSkripsi Sarjan

This research did to tested effect quantity of knife edge to effective
capacity of the tool, percentage of material that fall behind in the tool, and
percentage of material that didn’t slice completely. This research and completely
randomized design non-factorial. Based on research has been done, found the
effective capacity of the tool, percentage of material that didn’t slice completely
each, on one edge 45,82 kg/hr, 3,59%, 3,45%, on two edge 49,70 kg/hr, 4,07%,
4,11%, on three adge 68,58 kg/hr, 10,10%, 4,72%. The result of research showed
that quantity of knife edge give effect very real to effective capacity and
percentage of material that fall behind in the tool, and affect not real to percentage

in Plastic Waste Processing Device using Coconut Shell Fuel, supervised by
SAIPUL BAHRI DAULAY and AINUN ROHANAH.
The decrease of fossil resources and increase population are very
contradictive to energy consume for human life and social economy activity. So,
alternative energy is needed which environment friendly by the use of plastic
waste as fuel. This research as aimed to compare fuel from plastic (Polyethylene),
cosmetic bottle (HDPE) and aqua Bottle (PET) with kerosene. This research was
done in Agriculture Engineering Laboratory, and in Physical Chemistry
Laboratory of MIPA and Heat Engine Laboratory Faculty of Engineering in
August 2014 until finish using completely randomized non factorial design with
plastic (Polyethylene), cosmetic bottle (HDPE) and aqua Bottle (PET). The
parameters analysed were yield, value of heat and viscosity. The results, showed
