Abstract

Carbon emissions have become a pressing global concern because of its contribution to climate change and environmental degradation. Given the urgency to tackle climate change, especially by reducing carbon emissions, this study focuses on Africa’s leading CO2 emitters from 2000 to 2020. The aims of the study are; to examine whether there is evidence of an energy-Kuznets Curve among the leading CO2 emitters in Africa, to examine whether there is evidence of an FDI-Kuznets Curve among the leading CO2 emitters in Africa, and to Identify the turning points. The study employs an innovative analysis of unbalanced panel data utilizing sophisticated econometric techniques, the contemporaneous correlation methodology, which are; the feasible generalized least squares (FGLS), and the panel-corrected standard errors (PCSE) to uncover insights. The results reveal consistency across all employed techniques. The study confirms the existence of an Energy-Kuznets Curve among the leading CO2 emitters in Africa; it also finds evidence of a U-shaped relationship between foreign direct investment and carbon emissions among the leading CO2 emitters in Africa; finally, it also identifies crucial turning points at 2760.12kg and 2886.29kg of oil equivalent per capita for energy use and 6.89% and 6.17% for FDI inflow, respectively. By investigating the factors influencing carbon emissions and evaluating their impacts, our study offers valuable insights for policymakers. These findings can inform the development of targeted interventions to curb emissions intensity, enhance energy efficiency, and foster the adoption of renewable energy sources.

Abstract

Wilayah Bali merupakan daerah dengan tingkat seismisitas yang tinggi karena terletak di Zona Subduksi antara Lempeng Indo-Australia dan Eurasia (selatan) serta adanya struktur back arc thrust (utara). Gempa Bumi Seririt yang terjadi pada tanggal 14 Juli 1976 dengan magnitudo 6,2 SR merupakan salah satu gempa paling merusak di Bali. Oleh karena itu perlu dilakukan upaya mitigasi untuk melihat tingkat potensi bahaya bencana gempa bumi di wilayah Bali. Peak Ground Acceleration (PGA) merupakan pendekatan yang dapat dilakukan dengan cara menentukan intensitas seismik dari gempa bumi di suatu wilayah sehingga dapat diperkirakan risiko paling parah yang dapat dihasilkan dari suatu kejadian gempa bumi. Perhitungan nilai PGA dapat dilakukan melalui suatu pendekatan rumus empiris atenuasi khusus wilayah tertentu. Data yang digunakan berasal dari katalog gempa bumi ISC (1970-2019), USGS (1963-2019), dan data rekaman accelerograph BMKG (2012-2016) di wilayah Bali. Rumus empiris atenuasi dipilih dengan mempertimbangkan jenis gempa bumi dominan dan kondisi geologi di wilayah Bali. Terdapat 3 rumus empiris atenuasi yang digunakan yaitu oleh McGuire (1977), Donovan (1973), dan Esteva & Villaverde (1973). Rumus empiris atenuasi oleh McGuire (1977) menghasilkan nilai error terkecil berdasarkan perbandingan nilai PGA observasi dan nilai PGA kalkulasi. Analisa tingkat potensi risiko akibat gempa bumi dapat dilakukan berdasarkan peta percepatan tanah maksimum dan peta intensitas seismik maksimum di Wilayah Bali. Kabupaten Buleleng dan sekitarnya serta daerah paling timur dari Kabupaten Karangasem merupakan wilayah yang berpotensi terkena dampak paling parah jika terjadi gempa bumi bersifat merusak, sedangkan daerah paling selatan dari Pulau Bali memiliki dampak yang relatif ringan jika terjadi gempa bumi yang bersifat merusak.

Abstract

Renewable energy generated from sunlight (Solar Panels) can be formed as alternative energy that can be applied to a source of electrical energy in rice thresher equipment. The use of solar energy with a power of 240 WP through the object on the rice thresher is able to replace the rice thresher automatically which is more effective. The power generated by solar energy will be processed into a charging source for the Regulated Battery Charger which can be supplied at a voltage to the control circuit to drive the DC motor. The average voltage generated by solar energy is 0.000394 volts/lux with a maximum voltage of 36.2 volts and a DC motor of 350 watts. In addition, the speed of this rice thresher is 950.8 rpm and is able to produce very good rice cutting against the designed solar energy capabilities.
