Abstract

Electrical energy is an important requirement in the development of an area. North Sulawesi Province is one of the areas with rapid development. This is due to the establishment of a special industrial economic zone located in Bitung City. Special economic zones are a form of the Government of Indonesia's efforts to realize the vision of Indonesia Gold 2045. Thus, a new energy demand and supply prediction scenario is needed to overcome this. This study uses the End-Use method with two scenarios of demand and supply. The energy analysis software used is LEAP. The research data used consists of customer data, electricity consumption, North Sulawesi GRDP, list of installed power plants, plans for additional power plants. All data were obtained from various related agencies, including PT PLN, Department of Energy and Mineral Resources, BAPPEDA, BPS North Sulawesi. The results of the projection calculations for the Business as Usual (BaU) and Indonesia Emas 2045 demand scenarios have increased for all sectors. In the household sector the average growth was 6.00% and for business, public, and industry it was 3.00, 4.00 and 25.00%. The average growth for the projected energy demand for the Indonesia Gold 2045 scenario in all sectors is the same, which is 5.00%. In the BaU supply scenario, it is still dominated by PLTD, PLTU, PLTA, and PLTP, while in the Indonesia Gold 2045 scenario, PLTA has increased.

Abstract

Bengkulu city is facing groundwater problems where some of the groundwater is brackish. The study aimed to determine the structure of the subsurface layer through the propagation velocity of secondary wave (Vs) in a layer of porous medium in estimating the potential for groundwater. This research supported by resistivity data ​​and will be validated based on the depth of the well. MASW data was processed using WinMASW Professional 5.0 software to obtain a 1D profile of the Vs value, and Res2dinv software was used to obtain a 2D cross-section of the resistivity value. The results showed a decrease in the value of Vs in the porous medium layer from 133 to 358 m/s in the first path, and from 149 to 314 m/s for the second path. The decrease in the value of Vs is in the range of groundwater potential which is close to the depth of the resident's well, with the type of porous medium layer being sands and intact clays. The subsurface profile from the Vs measurement shows a good agreement with the resistivity value profile from the Geoelectric method. So, secondary wave propagation can be used in determining groundwater potential for a depth of < 10 m

Abstract

The research aims to figure out how to breed Philemon buceroides in captivity and make recommendations for conservation activities in-situ and ex-situ. Philemon buceroides are bred by giving the Pregnant Mare Serum Godadotrophin (PMSG) and Estrogen hormones and artificial insemination to birds who are sexually mature and physically healthy at least one year old. The birds in this study were Philemon buceroides that had been reared for at least a year to lessen stress. According to the researchers, the Philemon buceroides sample was acclimatized for 7 days in each birdcage. The treatment group was superovulated the next day to produce more eggs than normal, using PMSG hormone at a dose of 150 Im in 10 milliliters of ferologic Nacl / Kg BW once a day for three days. Only 10 milliliters of ferologic NaCl were given orally to the control group. The following day, lust/Estrus synchronization was performed utilizing the Estrogen hormone at a dose of 150 Im in 10 milliliters of ferological NaCl orally once a day for three days. Sperm was taken from male Philemon buceroides. As a result, synchronizing the reproductive hormones Pregnant Mare Serum Gonadotrophin (PMSG) and Estrogen in male and female Philemon buceroides considerably influenced the increase in ovulation, however the eggs generated by the mother Philemon buceroides have yet to produce chicks. Furthermore, obtaining male sperm is challenging. Just one sperm pulled out one drop from the three guys, while the other two did not

Abstract

This research studies the efficient method for heavy metal analysis in marine fish samples by atomic absorption spectrophotometry. The dissolution of the samples used the wet destruction technique in 2 ways. The first method uses a mixture of HNO3, H2SO4, HClO4 (1:2:1), and the second method uses a mixture of HNO3and H2SO4 (1:1). Tuna (Euthynnus affinis) was taken as Marine fish samples. The results showed that the first method took 180 minutes with a % recovery of 98.79% - 99.55%. In contrast, the second method took 240 minutes and a % recovery of 98.08% - 98.45%. The results of measurements by atomic absorption spectrophotometry (AAS) using standard calibration curve and standard addition techniques are as follows: using standard regression curve technique obtained Pb (0.664 ± 0.067) mg/kg, Cu (2.780 ± 0.01) mg/kg, Cd (0.192 ± 0.044) mg/kg, and Zn (1.824 ± 0.075) mg/kg, while the standard addition method obtained Pb (0.612 ± 0.016) mg/kg, Cu (2.364 ± 0.016) mg/kg, Cd (0.148 ± 0.029) mg/kg and Zn (1.692 ± 0.016) mg/kg. The calculation of the level of accuracy of the analysis showed that the standard addition method RSD gave a precision value of 0.97% - 3.76% and the standard curve method RSD with a precision of 5.76% - 31.77%. In conclusion, (1) Heavy metal content in tuna (Euthynnus affinis) is still within the permissible limits. (2) wet digestion technique using a mixture of HNO3, H2SO4, HClO4 (1:2:1) can be more efficient. (3) The measurement results of the standard addition method give more precise results

Abstract

Geothermal in Pawan and Pendalian IV Koto Villages is one of the post-volcanic geothermal areas in the Rokan Hulu Regency. This study aims to determine the characteristics of geothermal fluids and estimate reservoir temperature based on geothermometer estimation. The research method used in the study consisted of several stages, namely field data collection and fluid geochemical analysis. The research results from 12 hot springs plotted on the Cl-Li-B triangle diagram show that all hot water samples are dominated by Cl, indicating that the hot springs are far from the geothermal reservoir. The Cl-SO4-HCO3triangle diagram shows that all of the hot springs are bicarbonate water types dominated by HCO3. The Na-K-Mg triangle diagram shows that all fluid samples are in the immature water area, which indicates that the fluid has undergone a reaction with other elements or the influence of meteoric water is quite dominant. The results of calculations with a geothermometer, the estimated reservoir temperature in the geothermal area is in the range of 160.69°-176.76°C, which is included in the medium-temperature reservoir system. Geothermal in this area can be used as the geothermal potential for developing geothermal power plants.

Abstract

The effect of dispersion will interfere with the signal transmission. Several ways can be done in compensating the dispersion such as by utilizing dispersion compensator fiber (DCF) or chirp fiber Bragg grating (CFBG). The dispersion compensation schemes with DCF are expensive and it also causes nonlinear optical effects, meanwhile, the CFBG can reduce costs and promise better results. In this study, an Apodization Chirped Fiber Bragg Grating (ACFBG) has been developed as a dispersion compensator with Optisystem with non-return to zero (NRZ) 20 Gbps. It is found that the Gaussian Cubic-CFBG apodization with a size of 90 mm had the highest Q-factor evaluation of  20,776 dB for a 250 km dispersion compensation scheme. this result is much larger than the previous CFBG dispersion compensation scheme. This study also confirmed that the Gaussian Apodization was the best profile compared to Tanh Apodization, from the evaluation of the Q-factor, Tanh cubic-CFBG only obtained a Q-factor of 9.6 dB. Certainly, the high performance of ACFBG as a dispersion compensator is very useful to support optical communication systems
