Abstract

The research has been done using geoelectric resistivity method to estimate the volume of Manganese (Mn)  carrier rock in Empol sub-village, Central Sekotong Village, West Lombok NTB. Measurements was conducted with the Wenner configuration using a Resistivity Meter G-Sound GL - 4100. Data was modeled and calculated using three software, there are Res2Dinv 3.5, Surfer 10, and Rockwork 15.  The rocks that regarded as carrier mangaan is pyrolusite manganese (Mn02). The description and distribution of MnO2 can be determined from the results of 2-dimension modeling using Res2Dinv. Mn02 was detected in  almost all resistivity line with value around 0,023  Wm up to 9,8  Wm.  From the 3-dimension visualization processed using RockWorks 15 software, we obtained volume of pirolusit about 38,199 m3 of area 160,000 m2 and 100 m of thickness.DOI: 10.29408/kpj.v4i2.2731

Abstract

Gas karbon dioksida adalah salah satu jenis emisi udara yang dapat berasal dari berbagai sistem pembakaran. Gas karbon dioksida juga dapat dihasilkan dari hembusan udara sisa pernapasan manusia. Hal yang menarik adalah indikasi hubungan antara perubahan metabolisme tubuh dengan konsentrasi karbon dioksida yang dihembuskan oleh sistem pernapasan manusia. Di sisi lain, terdapat limitasi perkembangan teknologi di bidang pendeteksian konsentrasi gas karbon dioksida di dalam udara pernapasan sebagai biomarker akan keberadaan kondisi psikologi tertentu, seperti pada kasus plasebo (placebo effect). Oleh sebab itu, penelitian ini memiliki tujuan untuk mengidentifikasi hubungan antara tingkat atau besar konsentrasi emisi udara jenis CO2 dengan persentase kasus plasebo di masyarakat yang berada di daerah emisi. Penelitian dilakukan terhadap 90 sampel nafas di tiga sumber emisi yang berbeda, yakni E1, E2, dan E3. Kondisi plasebo diklasifikasikan menjadi tiga jenis, yakni PLS(-), PLS(+)P, dan PLS(+)N dengan kondisi psikologi yang berbeda-beda. Hasil penelitian menunjukkan bahwa sistem pengukuran konsentrasi gas karbon dioksida berbasis sensor MG-811 dapat digunakan untuk mengidentifikasi hubungan antara besar konsentrasi emisi terhadap persentase plasebo. Ketiga daerah sumber emisi menghasilkan emisi CO2 dengan konsentrasi yang bervariasi, yaitu berkisar 740 ppm hingga 790 ppm yang jauh lebih tinggi dibandingkan konsentrasi kontrol (< 405 ppm). Sejalan dengan hal ini diperoleh tingkat persentase plasebo yaitu PLS(+)N. Hasil tersebut meyimpulkan bahwa semakin tinggi konsentrasi emisi, maka semakin tinggi persentase kejadian plasebo (PLS(+)N). Semakin rendah tingkat konsentrasi emisi CO2, maka  semakin rendah persentase plasebo di masyarakat yang menjadi sampel.

Abstract

Lombok has become one of the leading tourist destinations, especially with the development of the Mandalika Special Economic Zone. One of the cultural products that has the potential to be offered to tourists is Lombok traditional weaving. The study aims to analyze the effect of the pH of the dye solution on the characteristics of the dyed fabric. The research method uses a mechanical thermal method to obtain anthocyanin powder extraction, standard staining methods namely mordan, staining, and fixation, as well as characterization using tensilons, Color Analyzer software, Hooloovoo, and Encycolorpedi website. The extraction of anthocyanin compounds from teak leaves (Tectona grandis) was successfully carried out by mechanical thermal method. Color analysis and identified color changes are significantly affected by differences in solution pH. The higher the pH used, the darker the color will be produced and the higher the level of color fading in the fabric. The smallest  E value is at pH 6 =5.364 and the largest  E value is at pH 14 = 17.145. However, an increase in pH tends to increase the tensile strength of the fabric. However, the optimum tensile strength condition was obtained in a solution of pH 12, which was 17.414 MPa, while at pH 13 and pH 14, the tensile strength of the fabric decreased to 16.071 MPa. Based on the analysis of the influence of pH of dye solution on fabric tensile strength, it was identified that a 6th-order polynomial model (determination coefficient R2 = 0.9479) was identified as accurate enough to model the influence of pH on fabric tensile strength. Therefore, this finding has potential in the textile industry, especially in increasing the economic value of Lombok weaving.
