Abstract

Every construction project certainly has constraint and barrier, to limit every constraint occurs in project conduction then it needs supervision or monitoring in carrying out of building activity. This research uses value result method to determine the time needed to finish and cost needed up to the finishing project. Here, there are there are three indicators attentioned in using result value method, they are BCWS, BCWP, and ACWP. The monitoring result from result value method calculation is that the estimation of the last finishing job are 123 days three days late from the normal is that 120 days in finishing. Whereas the cost spends up to the finishing job is estimated Rp. 612.512.649,00 lower than the cost determined, and it can be guess that the company get profits.Key words: project monitoring, result value methode, time, and cost.

Abstract

Population of massive people caused the trafic crowded, and demand to good transportation as personal such as two wheels aslo four wheels getting high. That condition needs attention especially on the intersection. Unbalance of vehicle numbers with road numbers which is already provided of green wendesday cause delay and queue long enough on the intersection. Phase management plan and optimum cycle timing are expected to increase its capacity on the intersection. By getting that situation so the writer conduct study about phase and optimum cycle timing on the intersection at KH. Wahid Hasyim Jombang street by using counting method MKJI 1997 and got side obstacle arround A arm with intermediate obstacle, on B arm got high obstacle, on C and D arm got low obstacle. So that it needs solution by fixing side obstacle arround the branch, widening the branch and management of private vehicle and also special heavy transport to closer B (KH. Wahid Hasyim street) in rush hours of morning and eveningKeyword : Signalize Branch, MKJI 1997, Jombang

Abstract

The quality of combustion in stoves press (blow-torch burner) can be improved in various ways. One way is use renewable fuel that is HHO gas, which is produced from HHO generator dry type, also by utilizing the waste oils as fuel. The addition of HHO gas and used oil in stove press (blow-torch burner) burning will reduce the volume of kerosene consumption.This study was conducted using true experiment with fuel kerosene + used oil as a control group were then compared to the fuel mix used oil and kerosene + HHO gas. Tests conducted on a test stove and combined with a self-designed HHO generator. HHO gas production rate that entering to combustion chamber as much as 2.3 LPM. HHO Gas and vapor mixing kerosene + used oil are combined in premix using ejector, by varying the fuel valve opening at openings 25% and 50%. Parameters measured were flame fire structure based on the contours of isothermal, the temperature distribution at each altitude, high fire, flame width, power fuel and conduction heat transfer that occurs.Based on the results of research showed that the fuel valve openings and the addition of HHO gas on the stove press (blow-torch burner) burning led to a decline in flame height, increase the width of the flame, increasing the temperature distribution, power fuel, as well as conduction heat transfer with increasing fuel valve openings and the addition of HHO gas.Keywords: stove press (Blow-torch burner), kerosene, used oil, HHO gas, HHO generator.Studi Eksperimen Pengaruh Penambahan Gas HHO37

Abstract

Pada beberapa komponen kendaraan sering dijumpai adanya kegagalan akibat menerima beban geser. Tujuan penelitian ini adalah untuk mengetahui pengaruh fraksi volume serat terhadap kekuatan geser komposit berpenguat serat ijuk(acak, anyam, acak) dengan resin polyester. Fraksi volume serat (Vf) yang digunakan pada penelitian ini sebesar 35%, 45%, 50%, 55% dan 60%. Metode pembuatan komposit dilakukan secara hand lay up dengan laminasi terdiri dari serat ijuk acak, serat ijuk anyam dan serat ijuk acak. Dimensi dan prosedur pengujian specimen uji geser mengacu pada standar ASTM D-1037. Pengujian geser dilakukan sebanyak tiga kali untuk masing-masing setiap kelompok uji. Foto makro dilakukan setelah dilakukan uji geser. Foto makro dilakukan pada penampang patahan uji geser untuk mengetahui pola kegagalan yang terjadi pada komposit. Hasil penelitian menunjukkan bahwa kekuatan geser komposit meningkat seiring dengan peningkatan fraksi volume serat. Peningkatan kekuatan geser terbesar terjadi pada fraksi volume serat (Vf)= 45% yaitu sebesar 9466,45 MPa, sedangkan kekuatan geser terendah terjadi pada fraksi volume serat(Vf)= 60% yaitu sebesar 7118,67 MPa. Identifikasi penampang patahan menunjukkan bahwa pola kegagalan secara umum didominasi lepasnya ikatan antara serat dengan matriks (delamination) disusul dengan putus atau patahnya serat. Kata Kunci: fraksi volume serat, kekuatan geser, penampang patahan dan serat ijuk
