Abstract:

Roads with soft subgrade have low bearing capacity. The result is non-uniform soil settlement. One way to overcome this is with soil stabilization. Stabilization of clay soil is done chemically with palm bunch ash and cement. The purpose of this study was to determine the bearing capacity of soil for the shear strength value of clay soil with variations in mixing 5%, 10%, 15%, 20% oil palm bunch ash, and 10% cement with a 7-day curing period, and then the samples were tested using a direct shear test tool SNI 3420: 2016.

Abstract:

CBR (California Bearing Ratio) value is usually used to determine the bearing capacity of a soil type. Soil conditions with low bearing capacity are often found in clay soil types. There are several ways to increase the CBR value of clay, one of which is by adding palm bunch ash. In this research, an analysis of changes in the CBR value of clay with addition of 5%, 7.5%, and 10% palm oil bunch ash. The results showed that the largest CBR value was obtained at the addition of 10% of palm oil bunch ash, which was 7.493%.

Abstract:

Soft clay soil has a relatively low subgrade bearing capacity and relatively large subgrade compression and lasts for a relatively long time so that it becomes a major problem in the development of transportation infrastructure. The aim of the research is to determine the effect of a mixture of palm bunch ash and variations of fly ash on the CBR value of clay soil and to determine the effect of a mixture of palm bunch ash and variations of fly ash on the permeability of clay soil. One of the efforts to improve soft clay soil is by adding palm bunch ash as a stabilizing agent on the soil. This

Abstract:

The proximate composition of the organic waste substrates used in cultivating Pleurotus ostreatus was analyzed, and the results revealed significant variations in various nutritional components among the substrates. Palm Chaff had the highest ash content (7.14%), followed by Oil Palm Empty Bunch (5.08%), Yam Peel (4.29%), and Saw Dust (1.36%). This indicated that Palm Chaff was the richest in minerals, while sawdust had the lowest mineral content. In addition, Yam Peel had the highest moisture content (8.46%), followed by Palm Chaff (5.87%), Oil Palm Empty Bunch (4.62%), and Saw Dust (2.83%).

Abstract:

Activities in healthcare facilities have a negative impact in the form of pollution due to waste disposal without proper processing. One of the most dangerous is lipid or fat waste in wastewater. Lipids are also a threat to the aquatic environment, such as those found in ditches and rivers. Oil/fat will cause pollution in the river and in the processing plant itself thereby reducing the efficiency of wastewater treatment. Oil and grease removal usually uses physical methods, namely by trapping oil/fat with a grease trap. The second uses a flotation process utilizing the force of gravity. It is
