Semarang Toll Road  Section ABC is one of many toll roads that are traversed by transport vehicles with a load exceeding the permit limit, especially for vehicles originating from the Port of Tanjung Mas. These overloaded vehicles cause a decrease in pavement condition due to pavement damage on Semarang Section ABC Toll Road Section. This study aims to determine the magnitude of the impact of overload vehicles on the remaining life of the road by using overload vehicle detection from the Weight in Motion Bridge system. The method used in this study refers to Bina Marga Pd T-05-2005-B and AASHTO 1993. Based on the results of the analysis that has been done, it can be concluded that there is a decrease in residual life due to overloading vehicles for the year 2022 in Section A, Line A reaches conditions of 26.93% and 37,46%; Section B Line A achieves pavement failure; Section C of Line A reaches 44.65% and 38.33% conditions; Section A Lane B reaches 32.02%; Section B Lane B achieves failure pavement; and Section C of Line B reaching 54.42% and 40.70%.

Abstrak Syntetic Rubber Latex atau getah karet buatan, merupakan salah satu polimer organik yang memperlihatkan resiliensi (daya pegas) atau kemampuan meregang dan kembali ke keadaan semula dengan cepat Bahan ini terdispersi dengan stabil dalam suatu surfaktan yang mengandung air, berwarna putih seperti susu. Pada saat mengering patikelnya bersatu membentuk lapisan film yang berlanjut. Polimer organik adalah suatu bahan yang terdiri atas molekul raksasa yang dibentuk oleh sekumpulan molekul sederhana yang dikenal sebagai monomer dari hasil uji pada campuran panas (hot mix) dengan mencampurkan aspal sebanyak 6.5 % dari berat campuran dan agregat yang telah dipanaskan dalam tempat pemanas, diaduk pada suhu 140⁰ C dan dicampur polimer, lalu dicetak pada suhu 120⁰ C. Persentase polimer yang dimasukkan adalah 10, 15 dan 20 % dari berat aspal. Dari hasil uji marshall menunjukkan semakin tinggi polimer ditambahkan dampaknya adalah nilai flow semakin tinggi, sedangkan nilai stabilitas dan nilai marshall quotient nya semakin rendah.. Kata kunci : polimer, beton aspal, marshall, stabiitas, flow

ABSTRACT On the implementation of the construction project there is a contract which is the will to cooperate between the owner and the contractor, the contract was made in writing and agreed upon between the parties concerned aware of the rights and obligations of each. However, not infrequently, in the implementation of irregularities and discrepancies in the implementation process so that it can result in failure of the construction work. This study aimed to determine the cause of the failure of the construction work as well as how the solution from the aspect of the law against the failure of the construction work in the project implementation in Jakarta that could potentially be a dispute between the parties. Conclusions from the study include: Failure of construction work in the implementation of the project according to the order of the number of occurrences are the jobs structure: construction, foundation, frame and roof cover, earthworks construction, architecture of, for building utilities. The factors causing the failure of construction works in the project implementation in order of the number of occurrences are due to: the working methods of construction work and the project location, building design, materials used tool to support the implementation of projects, human resources, contracts and irregularities of construction work. While the completion of a failure in the execution of construction works for the parties in terms of the legal aspects are: the legal settlement of the dispute between the parties generally accomplished by means of deliberation, in mediating the settlement of disputes can use a third part.

Work at height is a job with a high risk of accidents, such as in the formwork aluma system. Weak supervision and a lack of knowledge of the workforce on potential hazards and risk control of the formwork aluma system are some of the causes of the high incidence of work accidents in this work. This research was conducted on the formwork aluma system of the BRI Gatot Subroto tower project, South Jakarta. The goal is to determine the potential hazards and risk control of aluma system formwork. Risk analysis is carried out using the AS / NZS 4360: 2004 standard to determine the level of risk to the potential hazards of the aluma system formwork. Potential hazards in the formwork aluma system are falling, bumping, being cut, punctured and crushed, with the level of risk being at high, substantial, medium and low levels. Risk control is carried out by the control hierarchy, namely elimination, substitution, engineering, administration, and control of PPE.

Researches about plastic concrete(betik)have been done since 2004 by kusumo drajad s. Betik consistsof a mixture of cement, sand, plastic aggregates (pellets) and water, can be categorized as lightweight concrete which have the same compressive strength with the normal concrete, approximately 120 kg/cm2. The research prototype betik walls which is done today as the result of the development composision ofbetik , consist of 1portion of cement, 2 portions of sand and 4 portions of plastic aggregate (recycling product ) and 0,6 portion of water. Afterward, all materials were mixed and poured into plastic bottles of mineral water packaging (such as aqua, ades ). Before the bottles are filled in,it should be cut into24 cm high, assembled with bendrat wires, and added concrete steel reinforcement diameter of 8 mm at the center of the bottle into a series of blocks that consisting of 6 bottles. Based on the testing in physical properties of a block betik’s wall samples have been tested: the slump’s average value is 6cm, the bottom’s surface is quite smooth, no cracked and all intact, but there are several cross-section of bottle that has been filled betik not circle.the experiment also showed: the size of betik’s block : 8.5 cm widht, 48 cm length, 24 cm high and average weight of each block betik’s walls is 9.5 kg. Furthermore, the blocks of betik’s wall were arranged and bonded using mortar that has composition 1 portion of cement and 4 portions of sand. The block of betik’s wall also supported horizontally by using bendrat wire and vertically by using 8 mm concrete bar, and shaped a segment of betik’s wall into 1.5 x 1.5 m. Subsequently, the wall of segment was standed up and than taken off, so the wall collapsed. The results shown that the knots of bindrat or concrete bar were in good condition and didn’t fall. The other results in this study were the blocks of betik’s wall blocks that collapsed are still in whole condition and it can be used again. Keywords: betik, plastic pellets, walls, concrete
