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.

Abstract

Agriculture is the economic backbone and source of life for many communities in Indonesia, including the City of Palangkaraya. The Sumber Makmur Farmers Group is a clear example of an agricultural community that strives to increase crop production and manage organic waste sustainably. However, they often face obstacles in producing quality compost due to external weather influences. Through this community service, we can also increase awareness of the importance of sustainable and environmentally friendly agricultural practices. The Sumber Makmur Farmers Group can be an example for other communities in implementing simple but effective technology to increase agricultural productivity in a sustainable manner. Thus, the activity of making a protective roof for portable compost fertilizer systems is not only a technical contribution to local agriculture, but is also a real effort to advance community welfare and maintain environmental sustainability in Palangka Raya City.

Abstract

Traffic jams that occur in junior high schools during school hours can be prevented if before determining thelocation of the school, the school or other responsible parties first estimate the traffic generation on land use byknowing the magnitude of the generation, the geometry of the road sections in the area can be planned. school.The aim of this research is to obtain a movement generation model at schools in Palangka Raya City, which it ishoped can be used to estimate the number of movements coming to the school in the future, so that it can beused to anticipate problems arising from travel generation. This research was conducted at St. Paul CatholicMiddle School, Palangka Raya. The research used is quantitative descriptive research using survey methods. Themovement generation model for St. Paul's Catholic Middle School, Palangka Raya, after analyzing the simplelinear regression equation, which is most representative is Y4 = -2380,417 + 4,250 of 0.203. Factors that have astrong influence on the generation of movement at St Paul's Catholic Middle School in Palangka Raya are thenumber of students (X4) and the number of teachers and school employees (X5).
