Abstract

Seawater intrusion in Gili Trawangan, North Lombok Regency, can be identified through groundwater salinity testing. This study aims to evaluate changes in groundwater salinity values as an indicator of seawater intrusion in the region. The test was conducted by taking well water samples and analyzing them at the Lombok Island Health Laboratory. The results showed that the groundwater salinity value before the water withdrawal project by PT Berkat Air Laut in 2012 was 5.00‰. During the groundwater withdrawal project period (2013-2022), the salinity value increased to 5.71‰, and post-project, the salinity value reached 6.07‰. These findings indicate that groundwater in Gili Trawangan was classified as brackish water from the start, with increasing salinity values indicating seawater intrusion. However, this increase is still in the low category, at 0.71‰ during the project and 0.36‰ post-project, so it is not classified as significant water pollution.

Abstract

Mineral soil has a high bulk density and is a limiting factor as a nursery medium. For the application of nursery media, planting media that is light, large water holding capacity are also needed. The magot compost comes from the Magot Lingsar unit the Regional TPA of NTB Province and the soil contains pumice an average of 68.2% comes from Tanak Beak Village, Central Lombok Regency, which has potential as a medium for nurseries. The purpose of this study was to identify the Bulk Density and water holding capacity of magot compost and soil containing pumice with the control variable of mineral soil from Labuapi, West Lombok Regency. Bulk density analysis method by analyzing dry weight per unit volume on soil rings and water capacity by analyzing wet weight minus dry weight. The subjects studied were magot compost with size < 2 mm, soil containing pumice size < 2 mm and control soil mineral rice fields. The results showed that the lowest Bulk Density was magot compost 0.42 gr/cm3, soil containing soil 0,64 gr/cm3, and rice field soil 1.42 gr/cm3, this was because magot compost was residue from waste. While the largest water holding capacity was soil containing pumice of 42.67%, magot compost 22.00%, and paddy soil 6.33%, caused by the number of macro and micro pores in pumice, whereas in magot compost water is bound to the humus surface. Suggestions for further research are the permanent wilting point time test on plant seeds.

Abstract

One alternative energy that can be used as a substitute for fuel oil and gas is biomass energy such as briquettes. This study aims to determine the amount of heat, moisture content and ash content of briquettes made using hazelnut shells and glutinous rice adhesives that vary in adhesive concentration and particle size. This study used a complete randomised design (CRD) with variations in glutinous rice concentration of 20%, 30%, and 40% while the particle sizes used were 12 mesh and 24 mesh. The results showed that the adhesive concentration did not significantly affect the test parameters while the particle size affected the moisture content, ash content and calorific value of the briquettes. The highest calorific value was obtained by using 24 mesh particle size with 20% adhesive concentration with a calorific value of 5321 cal/g while the 12 mesh particle size produced the highest calorific value of 4704 cal/g at 20% adhesive concentration. The lowest moisture content value was obtained by using 24 mesh particle size with 20% adhesive concentration with a moisture content value of 6.9% while the 12 mesh particle size produced the lowest moisture content value at 20% adhesive concentration with a value of 7.4%. The lowest ash content value was obtained by using 24 mesh particle size with 30% adhesive concentration with an ash content value of 4.99% while the 12 mesh particle size produced an ash content value of 5.82%. The use of 12 mesh particle size is not in accordance with SNI standards because the heating value produced is still below 5000 cal/gr while the use of 24 mesh particle size is in accordance with SNI standards for all test parameters.
