Abstract

This study aims to determine the effect of the addition of superplasticizer in concrete mixtures on compressive strength. To achieve this goal, a laboratory study was conducted using 12 cylindrical specimens with a diameter of 150 mm and a height of 300 mm. There are three variations of superplastcizer addition and one variation of concrete without superplastcizer addition as control. The concrete cylinders were tested at 14 days. The coarse aggregate used is a combination of 2 types of aggregates, namely Banjarmasin Stone (50%) and Merak Stone (50%).From the test results, the average compressive strength of concrete without using superplasticizer was 27.10 MPa. The compressive strength of concrete using superplasticizer (mix design results) is 37.18 MPa. For concrete that uses less superplasticizer (reduced by 1% from the mix design results) results in a compressive strength of 34.06 MPa. While for concrete that uses more superplasticizer (increased by 1% from the results of the mix design) gives a compressive strength of 37.02 MPa. Concrete that uses superplasticizer has a greater compressive strength value than concrete without superplasticizer

Abstract

The use of coarse aggregate significantly influences the mechanical properties and overall quality of concrete. This study investigates the impact of different coarse aggregate sizes (10 mm, 20 mm, and 40 mm) on the compressive strength and elastic modulus of concrete at 28 days. The research was conducted as part of a thesis in the Building Engineering Education Program, Department of Vocational Technology Education, Faculty of Teacher Training and Education, Universitas Palangka Raya. The primary objective was to determine the compressive strength and elastic modulus values for concrete mixes using varying coarse aggregate sizes. The concrete mixtures incorporated different coarse aggregate sizes along with fine aggregate, water, and Portland Pozzolana Cement (PPC) type I from Gresik. The mix design followed the guidelines outlined in SNI 03-2843-2000 for normal concrete mixtures. Testing was performed on cylindrical specimens measuring 15 cm x 30 cm. Each aggregate size variation (10 mm, 20 mm, and 40 mm) was tested using 10 samples, and the tests were conducted at 28 days in the Laboratory of Building Engineering Education, Faculty of Teacher Training and Education, Universitas Palangka Raya. The average compressive strength at 28 days for the coarse aggregate variations of 10 mm, 20 mm, and 40 mm were 29.15 MPa, 28.60 MPa, and 28.50 MPa, respectively. The average elastic modulus at 28 days for the same variations were 3033 MPa, 3856 MPa, and 3950 MPa.

Abstract

One of the elective courses in the Building Engineering Education Study Program, FKIP, Palangka Raya University is Bridge Structure. Experimental study is a way of teaching and learning that involves student activity by experiencing and proving for themselves the process and results of experiments which are closely related to everyday life. On the subject of bridge structures, it is necessary to carry out experimental studies on bridge pillars. Pillars are part of the bridge's lower structure. The existence of pillars in river flows causes changes in river flow patterns. Changes in flow patterns will result in local scouring around the pillars. This research aims to determine the effect of pillar shape on the potential for local scour that occurs around the pillar. This research was carried out under steady uniform flow conditions with three discharge variations. The physical models of pillars used are rectangular pillars, cylindrical pillars and triangular pillars. The type of research used is experimental research. The research location was carried out at the Building Engineering Education Laboratory, FKIP UPR with glass channel media with dimensions of 200 cm long, 15 cm wide and 20 cm high. In the test with flow discharge Q1= 40.08 cm3/sec, the maximum scour in the middle of the pillar that occurred was (ds)= 0.2 cm and the average at the edge was (ds)= 0.3 cm for pillars with the shape rectangular, while for triangular and cylindrical pillars experiencing sedimentation, Q2= 100.20 cm3/sec. The maximum scour at the center of the pillar that occurs is (ds)= 1.3 cm and the average at the edges is (ds) = 1.4 cm for rectangular pillars, while for triangular and cylindrical pillars experiencing sedimentation, Q3= 107.04 cm3/sec. The maximum scour in the center of the pillar that occurs is (ds)= 1.5 cm and is flat -average at the edge is (ds)= 1.5 cm for pillars with a rectangular shape, while for pillars with a rectangular shape and cylinders experience sedimentation. The results obtained from this series of research are that the greater the discharge flowing in a channel cross-section, the deeper the local scour around the pillars will be and the best shape in this study is a cylindrical shape because it has the potential for the smallest scour depth.

Abstract

Fish farming is a promising business alternative, especially in rural areas such as Petuk Liti Village. With the potential of existing natural resources, good management is needed so that cultivation results can be optimal (Iskandar & Muslih, 2022). One important aspect of fish farming is controlling water quality, especially water level, which affects fish health and growth (Rahmadani, 2021).However, the challenge faced by fish farmers is the difficulty of monitoring water levels in real-time, so that decisions are often made that are not appropriate, which can be detrimental to cultivation results. Therefore, this PKM activity aims to develop a water level monitoring station based on remote camera technology (GSM) which is implemented in Petuk Liti Village, Pulang Pisau Regency, Central Kalimantan.The monitoring station designed in this research consists of several main components, including a monitoring camera, a water level sensor, and a GSM module which functions to transmit data.The output target of this service is expected to make a significant contribution in increasing the efficiency and effectiveness of fish farming in Petuk Liti Village. With a monitoring station, farmers will be quicker and more accurate in taking the necessary actions, so that cultivation results can be optimal.

Abstract

Peatlands are an ecosystem that has an important role in the environment, including carbon storage, biodiversity habitat, and water availability (Murdiyarso et al., 2010). However, peatlands are also very vulnerable to fire, especially in extreme dry season conditions (Page et al., 2002). Peatland fires can cause significant environmental losses, including greenhouse gas emissions, loss of biodiversity, and negative impacts on public health due to the smoke produced (Masykur et al., 2019). Therefore, efforts to prevent peatland fires are very important to maintain the sustainability of this ecosystem and public health. The hydram pump method was chosen as an innovative solution in this research because of its ability to pump water continuously without requiring an electricity or fuel source. This makes it a sustainable and environmentally friendly alternative for wetting peatlands, which in turn can increase soil moisture and reduce the risk of fire (Wardhana et al., 2021). By utilizing this method, it is hoped that soil moisture can be maintained, making the land less susceptible to fire. The type of research used is experimental research. The research location was carried out at the Building Engineering Education Laboratory, FKIP UPR with a hydram pump and a drip irrigation system on differences in land elevation from plant water sources and water use efficiency. The target achieved is that this research will be published in the SINTA 5 and HKI Accredited Journals.
