Abstract

The use of recycled plastic waste as a binder for paving blocks has been reported in a number of previous studies. However, most of these studies focus on feasibility and do not clearly explain how different plastic types behave mechanically over time. In this study, the compressive strength performance of paving blocks made from polypropylene (PP), polyethylene terephthalate (PET), and high-density polyethylene (HDPE) was experimentally compared using sand or fly ash as fillers. All mixtures were prepared with a fixed composition of 60% plastic and 40% aggregate. Compressive strength testing was carried out at 28 and 56 days using three specimens for each mix. The results show that the HDPE–sand mixture achieved the highest compressive strength at 28 days, reaching 15.7 MPa. Nevertheless, a noticeable reduction in strength was observed at 56 days, particularly in the HDPE-based mixtures. This reduction is mainly associated with polymer shrinkage and the development of interfacial stresses between the plastic binder and the aggregates. Overall, the results indicate that plastic-based paving blocks can meet the requirements of SNI 03–0691–1996 for light-duty applications, although their long-term mechanical stability remains a limitation that needs further attention.

Abstract

As an archipelagic country, Indonesia has extensive coastal areas that are intensively developed for infrastructure. Kosambi District in Tangerang Regency is one of the rapidly growing coastal regions due to its proximity to Soekarno–Hatta International Airport. However, the area is predominantly underlain by soft marine clay soils with low bearing capacity and high compressibility, which pose challenges for infrastructure development. To improve soil stability, soil stabilization methods are required to enhance unconfined compressive strength and undrained shear strength. This study aims to analyze the effect of cockle shell powder addition on the unconfined compressive strength and undrained shear strength of soft marine clay. Laboratory tests were conducted on untreated soil and soil stabilized with 5%, 10%, 15%, and 20% cockle shell powder by dry weight of soil. The results indicate that the optimum performance was achieved at a 10% addition, resulting in a 24.86% increase in unconfined compressive strength compared to untreated soil. In addition to improving strength, the addition of cockle shell powder reduced water content and enhanced interparticle bonding, thereby improving soil stability. These findings demonstrate that cockle shell powder has strong potential as an effective stabilizing material for soft coastal clay soils.

Abstract

Abstrak Mendesain suatu bangunan tingkat tinggi dengan tidak menggunakan plafon dibutuhkan perencanaan yang ekonomis tanpa mengurangi kekuatan dan keindahan dari bangunan tersebut. Balok tinggi berlubang dengan material struktur beton digunakan untuk menghindari terjadinya sistem utilitas pada suatu bangunan tingkat tinggi dengan tidak menggunakan plafon. Balok tinggi berlubang ini ditinjau menggunakan metode Strut and Tie Model (STM). Untuk mengatasi permasalahan yang ada biasanya para perencana merancang daerah D (Disturbed Region) dengan menggunakan konsep pendetailan berdasarkan aliran gaya, sehingga metode strut and tie merupakan pendekatan yang sesuai untuk menganalisis struktur beton di daerah D. Program analisa struktur digunakan untuk melakukan analisis gaya dalam berupa momen dan geser pada struktur beton balok tinggi berlubang. Hasil analisis yang diperoleh pada struktur beton balok tinggi berlubang yaitu bahwa semakin dekat lubang balok dengan tumpuan maka nilai tulangan lentur akan lebih tinggi dan semakin bertambah pula tulangan gesernya. Kata kunci: Balok Tinggi Berlubang, Daerah D, Metode Strut and Tie  Abstract Designing a high rise building without using a ceilings requires an economical plan without reducing the strength and the art of the building. The deep beam with holes, which have the structure of concrete materials is need to be used to avoid the utility system in a high rise building without ceilings. This deep beam with holes is reviewed by the Strut and Tie Model (STM) method. To solve the existing problems, planners usually design the D region (Disturbed Region) use the concept of detail based on the flow of force. So the strut and tie method is an appropriate method to analyze the structure of concrete at D region (Disturbed Region). The program of analysis structure is used to analyze the internal forces, which are Moment and Shear, in the deep beams with holes' structure. The result of the analysis in the  deep beam concrete with holes is the more position of the hole is close to its pedestal, the value of the Flexural reinforcement will be more increase, and teh Shear reinforcement will be higher too. Keywords: Deep Beam Hollow, D Region, Strut and Tie Model

Abstract

Abstrak Perencanaan struktur beton biasanya dilakukan dengan berdasarkan asumsi dari Bernoulli dan Navier untuk menganalisis penampang akibat momen lentur. Distribusi regangan dianggap linier dan ini dianggap masih berlaku meskipun penampang telah retak. Balok tinggi merupakan salah satu contoh kasus pada suatu elemen struktur yang dapat mengakibatkan terjadinya distribusi tegangan non linier, sehingga asumsi diatas tidak berlaku. Balok dikatakan balok tinggi apabila rasio bentang terhadap tingginya lebih kecil dari lima. Salah satu alternatif pendekatan untuk mengatasi elemen struktur seperti balok tinggi adalah menggunakan pendekatan Strut and Tie Model, yaitu dengan membagi struktur dalam daerah B (Bernoulli) dan D (Disturb) dan menggambarkan alur gaya (load path) sebagai transfer gaya yang terjadi pada struktur beton bertulang pada kondisi retak akibat pembebanannya. Parameter-parameter dari Strut and Tie Model yaitu batang tekan (strut), batang tarik (tie) dan titik nodal (nodal zone) sebagai daerah pertemuan. Tujuan dari tulisan ini adalah untuk menganalisis alternatif perencanaan/desain tulangan struktur balok tinggi beton bertulang diatas dua tumpuan sederhana akibat beban merata yang dikonversi menggunakan beban terpusat 2 titik pembebanan.Metode yang digunakan adalah Strut and Tie Model yang akan menghasilkan luas tulangan longitudinal yang lebih kecil dengan selisih 25%, di mana dengan luas tulangan yang lebih kecil dari segi kekuatan masih memenuhi syarat. Hal ini menunjukkan bahwa perhitungan perencanaan balok tinggi tanpa bearing plate dengan menggunakan metode Strut and Tie Model pun dapat lebih optimum/efisien. Kata kunci: Prinsip Bernoulli, Strut and Tie Model, D - Region, B - Region   Abstract Concrete structure planning is usually carried out based on the assumptions of Bernoulli and Navier to analyze the section due to bending moments. The strain distribution is considered linear and it is considered still valid even after the section has cracked.  The deep beam is one example of a structural element that can result in a non-linear stress distribution, so the above assumption does not apply. A beam is said to be a deep beam if the span to height ratio is less than five. One alternative approach to dealing with structural elements such as deep beams is to use the Strut and Tie Model approach, namely by dividing the structure into areas B (Bernoulli) and D (Disturb) and describing the load path as a force transfer that occurs in the concrete structure. Reinforced in cracked conditions due to loading. The parameters of the Strut and Tie Model are the strut, tie, and nodal zone as the meeting area. The purpose of this paper is to analyze the alternative planning/design of reinforced concrete beams structure on two simple supports due to evenlydistributed loads that are converted using the two-point load centered load. The method used is the Strut and Tie Model which will produce a smaller area of longitudinal reinforcement with a difference of 25%, where the area of reinforcement is smaller in terms of strength still meets the requirements. This shows that the calculation of deep beam planning without bearing plate using the strut and tie model method can be more optimal/efficient. Keywords: Bernoullis Principle, Strut and Tie Model, D - Region, B - Region

Hasil penelitian ini menunjukkan bahwa suhu pembakaran mempengaruhi kuat tekan beton pumice dengan pasir Muntilan pada semua komposisi proporsi. Semakin tinggi suhu pembakaran maka semakin besar penurunan yang terjadi. Besaran penurunan kuat tekan akibat kenaikan suhu pembakaran berkisar antara 0,16% hingga 55,38% lebih lambat dibandingkan dengan beton tanpa menggunakan batu pumice Kata kunci: Beton, Batu Pumice, Performa Beton  Abstract Concrete that has been burned at 400° C will experience degradation to a residual compressive strength of 58.40%. This will affect the strength of the concrete structure and will cause the concrete to become brittle, thus allowing the structure to fail. Then it will require passive fire protection by using materials that have some resistance to the fire. One material that has the potential to create fire resistance is pumice stone. The purpose of this study was to determine the value of compressive strength and the rate of reduction in compressive strength of Muntilan sand pumice concrete due to the changes in combustion temperature of 27ËšC,300ËšC, and 600ËšC. In this study, used a 45 pieces concrete cylinder with a diameter of 15 cm and a height of 30 cm. with variations of pumice stone proportion of 0%, 25%, 50%,75% and 100% of the volume of coarse aggregate with a water cement ratio of 0.5. Compressive strength test with a compression device at the age of 28 days. The results of this study indicate that the combustion temperature affects the compressive strength of pumice concrete. The higher the combustion temperature, the higher the strength reduction that occurs. The amount of reduction in compressive strength due to an increase in combustion temperature ranged from 0.16% to 55.38% of the control specimens. Keywords: Pumice, Compressive Strength, Temperature
