Danar A.W Gautama, Petrisly Perkasa, Tuah — Fri, 29 Dec 2023 00:00:00 +0000

Land and peat forest fires in Indonesia are a serious environmental problem, especially in the years that experience the El Nino phenomenon. El Nino causes dry and hot conditions that trigger fires. One of the methods used to extinguish fires is water bombing, which is spraying water from the air using planes or helicopters. The purpose of this study is to analyze the effectiveness and efficiency of the water bombing method in dealing with land and peat forest fires in Indonesia. This study uses secondary data from various sources, such as government reports, research institutions, mass media, and non-governmental organizations. The data is then analyzed using descriptive, comparative, and evaluative methods. The results of the study show that the water bombing method has some advantages, such as fast, flexible, and able to reach areas that are difficult to access. However, this method also has some disadvantages, such as expensive, risky, and less effective in extinguishing fire in the peat soil. Therefore, this study recommends that the water bombing method should be used as one part of a comprehensive fire control strategy, which involves prevention, detection, and recovery. This study also suggests the need for improved coordination, regulation, and innovation in the use of the water bombing method in Indonesia.

Stunting is a condition of chronic malnutrition in children which can impact children's motor and verbal development as well as affect their cognitive development and productivity in adulthood. The prevalence of stunting in Indonesia in 2021 was 24.4%, while the prevalence rate of stunting in Central Kalimantan in 2021 was 27.4% and decreased in 2022 to 26.9%. There has been a decrease in the stunting prevalence rate of around 0.5%, but this reduction still needs to be improved so that there is an acceleration in the reduction in the stunting rate. The aim of carrying out this activity is to provide education regarding the dangers of stunting in children and efforts to prevent stunting through training in developing potentially nutritious food innovations to prevent stunting, so that it can accelerate the reduction in stunting rates and become a solution for local communities in improving their standard of living. The method used in this activity is a lecture using slide media and practice in making nutritious food for toddlers. The results of the outreach show that the community understands the dangers of stunting on children's growth and development and the community is able to innovate nutritious food for toddlers.

TRAINING ON MAKING A WATER LEVEL INSTRUMENT AS AN EARLY WARNING SYSTEM FOR PEATLAND IN TUMBANG TAHAI VILLAGE, CENTRAL KALIMANTAN

Fri, 29 Dec 2023 00:00:00 +0000

Indonesia has 14,905,575 ha of peatlands spread across Sumatra (43.18%), Kalimantan (32.06%) and Papua (24.76%) (Balai Besar Sumberdaya Lahan Pertanian, 2011). The area of peatland in Central Kalimantan reaches 2.65 million ha or 16.83% of the total area of Central Kalimantan (Balai Besar Litbang Sumberdaya Lahan Pertanian, 2013). Land and forest fires are becoming increasingly severe not only in Central Kalimantan, but also in other regions. This is triggered by activities where peatlands are used for agriculture or plantations coupled with the construction of drainage canals, causing peat water to dry out and become flammable during the dry season. In 1997, catastrophic fires destroyed no less than 2.2 million hectares of peat swamp forest, and destroyed 0.14 - 0.17 Gt of peatland carbon. In addition, it also caused several health problems, for example in Central Kalimantan, during the fires in 2015 there was data on cases of acute respiratory infections (ARI) in Central Kalimantan until the fourth week of September 2015, the number of sufferers reached 20,274 people (KMNLHRI and UNDP; 2015). These forest fires also cause great losses in the socio-economic field. This service aims to prevent drought in peatlands by measuring the water level at several points in Tumbang Tahai Village by measuring the water level so that an Early Warning System for peatland drought is formed in the village. It is hoped that the community of Tumbang Tahai Village in particular and the people of Central Kalimantan in general will be able to prevent peatland drought and this can be an initial experience in the practical experience of making, installing and using a water level measuring instrument.

MEASUREMENT OF WATER RETENTION OF PEAT SOIL IN CANAL BLOCKING USING PRESSURE PLATE CHAMBER

Fri, 29 Dec 2023 00:00:00 +0000

Measuring air retention in constructed canal blockage is critical for determining changes in air content after canal blocking. The purpose of this study is to assess the influence of changes in levels on air retention values measured at three depths, namely 0-20 cm, 20-40 cm, and 40-60 cm, at four transect sampling stations created at a distance of 10 m to 260 m from the canal block. Changes in bulk density, porosity, and peat volume affect groundwater. Peat soil samples were collected from burned peatlands, and canal blocks were constructed. A pressure plate chamber was used to assess air retention. The findings of the investigation revealed that the air retention pattern of peat soil at 16 test sample locations was at maximum at PF 0.2 at each depth. At higher pressures (pF 2-4.2), peat groundwater is strongly bonded by peat soil particles. The average bulk density of peat is 0.2 2 and the porosity value is 86.79%. The higher the air content at each pF value has no influence on the porosity and bulk density values. Changes in air content between pF 2.0 and 4.2 lower average peat volume by 7.4%. The size of this value is assumed to be determined by the peat's type, maturity, and decomposition value.

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

Vontas Alfenny Nahan, Topan Eka Putra, Revianti Coenraad — Fri, 29 Dec 2023 00:00:00 +0000

Currently, energy needs are increasing greatly, this is influenced by increasing population growth and human activity. The development of simpler renewable energy must be encouraged to meet energy needs, at least to meet the domestic energy needs of households. A hydram pump is a tool that can utilize water flow to produce kinetic energy which is then converted into potential energy to lift water to a certain height. This potential energy can be converted into electrical energy through a generator. A hydram pump is a tool used to raise water from a low place to a higher place automatically with energy originating from the water itself, namely because of the height of the falling water which is used to press the valve on the hydram pump and result in a water hammer when the water is stopped automatically. suddenly, then the change in momentum of the fluid mass will also increase the pressure suddenly. This research was carried out at the Mechanical Engineering Education Laboratory at Palangka Raya University with the methods described which will include experimental steps, data collection and analysis to be carried out. This research aims to develop an optimization model for the use of water flow in the hydram pump reservoir as a source of sustainable electricity generation on a laboratory scale. The results of this research have been carried out 4 times with the height of the turbine from the bottom of the experimental floor being 3 m while the size of the exhaust valve opening is ± 4 cm and the height of the water plunge from the barrel to the hydram pump is 2 m; 1.5m; 1.2 m is able to produce stable turbine rotation so that the lights come on. However, at a height of 1 m from the barrel to the hydram pump, the turbine rotation produces dim lights.
