Abstract

Confusion of guests/address seekers is a problem they face because of the same 3 housing names, namely Puri Kartika Asri (in Tasikmadu; Jl. Raden Panji Suroso, Blimbing, Malang; and Arjowinangun, Kedungkandang, Malang), but different locations accompanied by 4 developer names are the same, namely Puskopad (Tasikmadu; Jl. Panglima Sudirman; Jl. Sulfat area; and Jl. Mayjen Sungkono, Singosari Malang). The purpose of installing writing is to help guests or grab/gojek drivers or address or postal/delivery service companies for letters/documents/goods/entrusted or guests to a Multipurpose Building in a residential area. The writing method includes deliberations with residents to determine the design of the letter model for the construction of the pergola (where the vines grow) in the form of a gate at the housing gate, ordering letters from stainless steel, embossed type that is rust/weather resistant and roofing bolts to tie letters on the frame, construction that is linked to the framework of the pergola, assessment of robustness and authenticity of placement, adjustment of position, and submission to the Head of RT where the address is posted. The results of the installation of writing in the form of displaying a clear address which implies that there is no more confusion for guests/address seekers to meet those they are addressed to with the conclusion that the address writing clearly acts as a housing-area identity, resulting in synergy between State Polytechnic of Malang and the community in obtaining the benefits of assistance and beauty at RT 01-03 at RW 06 Tasikmadu, Lowokwaru, Malang.

Abstract

The problems faced are the lack of beauty and obstructed views at the mouth of the road where there is a narrow brick gate access and the difficulty of installing decorations during the commemoration of the Independence Day of the Republic of Indonesia. The purpose of community service is to improve the beauty of the environment and ease when installing decorations of August and wider entry-exit access points. The method applied is consultation with residents to determine the design of the pergola from rectangular pipe construction that can be propagated by vascular plant such as grapes/passion fruit/betel, making pergola, and demolishing gates, installing a construction frame with cast-concrete foundation legs so that they are sturdy and not corroded, assessing the robustness and beauty of the placement, and submitting it to the Head of the neighborhood Association. The results obtained are in the form of wider access roads for 2 sedans passing each other, the driver's view is not blocked, the beauty is increased, and the installation of the decoration can be easier. The installation of a pergola can have the implication of making traffic flow smoother and residents must be more careful, especially children who cross the road in front of their houses with the conclusion that pergola vascular plant can be used as a housing icon, resulting in a synergy between the State Polytechnic Malang and residents who are satisfied with the assistance and beauty of the environment in the RT 03-RW 06 Tasikmadu, Lowokwaru, Malang city.

Abstract

This research is to direct the mixture of air and fuel exactly to the top of the midpoint of the dome in the cylinder head. In addition, Squish Head also determines the character of the motorcycle. Moreover, what is very prominent in the initial pull is that if the compression ratio is denser, the pull is lighter.This study aims to determine the effect of changes in the slope angle of the squish head of 15, 17 and 19 degrees on compression and torque. In this study, experimental research is used with a quantitative method, where information that can be calculated and measured is factual because it is in the form of numbers. Researchers to get the data will conduct tests using the dynotest tool.Changes in slope of the squish head have an effect on the torque. At an angle of 15 degrees, torque is produced at 9.91 N.m at 6000 RPM engine rotation. At an angle slope of 17 degrees, the torque increases by 0.14 N.m to 10.05 N.m at 6000 RPM engine rotation. At an angle of 19 degrees, the torque increases by 0.17 N.m to 10.22 N.m at 6000 rpm.
