<p>The quality of cement is very important because it will greatly help the production well activities especially to make the construction of wells can last long. In this study the influence of lost circulation material (LCM) was analyzed, such as Bagasse, Coconut Fibers, Banana Tree Bark and Sawdust on the physical properties of G-class cement such as rheology, density, free water content, thickening time, and compressive strength. This research was conducted in the laboratory by varying the percentage of LCM from 0% to 6% and temperature from 95oF to 200oF. From this research, it can be known <br />that the addition of LCM can change the physical properties of cement. The highest increase of plastic viscosity (PV) and yield point (YP) values was occurred at 6% concentration of Bagasse, Coconut Fibers, Banana Tree Bark and Sawdust that was 105 cp – 92 lbs/100ft2, 105 cp – 90 lbs/100ft2, 90 cp – 110 lbs/100ft2, and 95 cp – 110 lbs/ft2. The longest thickening time was occurred at 6% concentration of Bagasse, Coconut Fibers, Banana Tree Bark and Sawdust with a soaking temperature of 200 oF which that was 65 minutes, 60 minutes, 66 minutes, and 63 minutes. The highest reduction of density <br />value occured at 6% concentration of Bagasse, Coconut Fibers, Banana Tree Bark and Sawdust that was 15.0 ppg, 15.2 ppg, 15.2 ppg and 15.0 ppg. The decrease in the highest free water content value occurs with the addition of 6% in each type of LCM, namely 0.9 ml, 0.95 ml, 0.9 ml and 1 ml. The increase in the strong press rate occurs in the addition of 1% sugar cane, which is 2838 psi; 1% Coconut fibre is 2926 psi, 0.5% of the banana tree bark is 3080 psi and 1% of sawdust is 2728 psi all at 200 º temperature.</p>

This research was conducted to increase the value of compreive strength by adding palm shell ash to the base soil of brick. The palm oil shell was got from the result of the disposal of  Incasari Raya Factory Damasraya. The soil as the basic material of the brick was got from the brick’s manufactory Gunung Sariak Padang. The persentage of palm shell ash in the soil mixture was 0%, 5%, 15% and 25% from the soil dry weight. The test consisted of physical properties test and mechanical properties test. The physical properties test consisted of water content test, spesific gravity test, Atterberg limit test, and grain size analysis test.The mechanical properties test consisted of compaction test, compressive strength test and flexural strength test. The water content in manufacture brick was 0,85% γd maximum on wet side optimum of the soi. All the process of the brick is manufactured with manual fabrication. The result of the test showed that the values of spesific gravity (Gs), plastic limit (PL), shrinkage limit (SL),maximum dry density, optimum of water content, and compressive strength of brick increased. Mean while the liquid limit (LL),passing of sieve no. 200 in three days care, plastic index (PI), decreased. For flexural strength, at first increased, along with addition percentage from palm shell ash, this value inclined decreased. The optimum result was got 5%        palm shell ash in the soil mixture.

It is widely accepted that soil is a mixture of mineral constituents that have accumulated over time. The physical characteristics of soil vary according to the mineral and organic matter content and the process of formation. The soil`s unique characteristics have been the subject of research in the field of civil engineering, which has continued to evolve to the present day due to the land`s requirement for civil engineering construction, such as road paving. As a result, the current study sought to determine the similarity of soil samples based on their physical properties and California Bearing Ratio (CBR) values, as well as the relationship between the soil`s physical properties and CBR values. To our knowledge, there is hardly little research in the literature investigating the topic under our investigation. Furthermore, we also mapped the physical characteristics and CBR values of numerous distinct soil samples using a Geographical Information System (GIS). This study concentrated on the West Lampung Regency, specifically the area between Bukit Kemuning in Central Lampung and Liwa in West Lampung, along the lines of Bukit Kemuning, Liwa, and Krui, all the way to the Lampung – Bengkulu province border. The soil samples from the area were taken for two tests: the unsoaked CBR test and the soaked CBR test. The results of the tests show that a 31-kilometre distance does not result in a significant difference in soil properties, which are generally similar except in clay-rich areas. Furthermore, the results of the laboratory analysis show that the amount of water in the soil sample affects the Liquid Limit (LL), Plastic Limit (PL), Maximum Dry Density (MDD), and CBR values; the lower the plastic limit value, and thus the lower the CBR value, the less water in the soil. The implications of the current findings are also discussed.

Soil Moisture Monitoring

Abstract Soil moisture has important implications for meteorology, climatology, hydrology, and agriculture. This has led to growing interest in development of in situ soil moisture monitoring networks. Measurement interpretation is severely limited without soil property data. In North Carolina, soil moisture has been monitored since 1999 as a routine parameter in the statewide Environment and Climate Observing Network (ECONet), but with little soils information available for ECONet sites. The objective of this paper is to provide soils data for ECONet development. The authors studied soil physical properties at 27 ECONet sites and generated a database with 13 soil physical parameters, including sand, silt, and clay contents; bulk density; total porosity; saturated hydraulic conductivity; air-dried water content; and water retention at six pressures. Soil properties were highly variable among individual ECONet sites [coefficients of variation (CVs) ranging from 12% to 80%]. This wide range of properties suggests very different behavior among sites with respect to soil moisture. A principal component analysis indicated parameter groupings associated primarily with soil texture, bulk density, and air-dried water content accounted for 80% of the total variance in the dataset. These results suggested that a few specific soil properties could be measured to provide an understanding of differences in sites with respect to major soil properties. The authors also illustrate how the measured soil properties have been used to develop new soil moisture products and data screening for the North Carolina ECONet. The methods, analysis, and results presented here have applications to North Carolina and for other regions with heterogeneous soils where soil moisture monitoring is valuable.
