Analisis Potensi Energi Listrik dan Ekonomis Biogas dari Ampas Kelapa Provinsi Riau: Analisis Potensi Energi Listrik dan Ekonomis Biogas dari Ampas Kelapa Provinsi Riau
No full textBPS data from 2021 states that coconut production in Indonesia is the largest in the world, with a total production of 988.3 thousand tonnes of coconuts. The largest coconut production comes from Riau Province, with a production of 1,100 tonnes. Generally, coconuts are used to make coconut milk, leaving behind coconut pulp as waste. This waste is considered garbage because it no longer has any beneficial value, so it is disposed of directly. This disposal has an impact on the environment because biomass waste that is disposed of directly will cause a foul odour and methane gas emissions that are 20 times more harmful than CO2 emissions, even though coconut husk waste contains nutrients that can be processed into a new energy source in the form of biogas. This research aims to analyse the biogas potential that can be generated from coconut husk waste, including the potential for electricity generation and its economic analysis. This research uses the anaerobic respiration method to produce biogas in an anaerobic digestion reactor simulated using the SuperPro Designer application. From the research conducted, it was found that the potential biogas that can be produced from coconut husk waste in a year in Riau Province is 15,321,231.9 m3, which is obtained from 134 tonnes of coconut husk waste in Riau Province in 2021. In addition, the biogas produced is capable of generating 141,703,473 kWh of electricity per year, with a potential revenue of Rp. 212,555,209,500 and an annual profit of Rp. 163,532,903,700. With a B/C ratio of 1.26 and a payback period of 9.6 months, it can be said that this investment is profitable and feasible to be realised.

Data BPS tahun 2021 menyebutkan bahwa produksi kelapa di Indonesia terbesar di dunia dengan jumlah produksi sebesar 988.3 ribu ton kelapa, dengan produksi kelapa terbesar dari Provinsi Riau dengan produksi 1.100 ton . Pada umumnya kelapa dimanfaatkan untuk dijadikan santan, dan meninggalkan limbah berupa ampas kelapa. Limbah ini dianggap sampah karena tidak memiliki nilai manfaat lagi, sehingga langsung dibuang Pembuangan ini memiliki dampak terhadap lingkungan, karena limbah biomassa yang dibuang secara langsung akan menimbulkan bau busuk dan emisi gas metana yang 20 kali lebih berbahaya dibanding emisi CO2, padahal limbah ampas kelapa memiliki kandungan nutrisi yang dapat diolah menjadi sumber energi baru berupa biogas. Penelitian ini bertujuan untuk menganalisis potensi biogas yang dapat dihasilkan dari limbah ampas kelapa, mencakup potensi energi listrik yang dapat dibangkitkan dan juga analisis ekonomis nya. Penelitian ini menggunakan metode respirasi anaerob untuk memproduksi biogas dalam reaktor anaerobic disgestion yang disimulasikan dengan menggunakan aplikasi superpro designer. Dari penelitian yang telah dilakukan diperoleh potensi biogas yang dapat dihasilkan dari limbah ampas kelapa dalam setahun di Provinsi Riau adalah sebesar 15.321.231,9 m3 yang diperoleh dari 134 ton limbah ampas kelapa Provinsi Riau tahun 2021. Selain itu biogas yang dihasilkan mampu mebangkitkan energi listrik sebesar 141.703.473 kWh / tahun dengan potensi pendapatan yang dapat diperoleh sebesar Rp.212.555.209.500 dengan keuntungan tahunan sebesar Rp.163.532.903.700. Dengan nilai rasio B/C 1,26 dan periode pengembaian modal selama 9,6 bulan, dapat dikatakan bahwa investasi ini adalah menguntungkan dan layak untuk dapat direalisasikan..

Harnessing Machine Learning to Decode YouTube Subscriber Dynamics: Regression Predictive Models and Correlations
Get PDFYouTube has grown and become a digital media giant. Content creators continue to struggle with predicting subscriber growth. Due to viewers' changing interests and the vast amount of information, it is challenging to determine which factors most influence subscription behavior. Optimizing content strategy and ensuring channel growth need an understanding of these traits. This study uses linear regression models (LR), neural networks (NN), and Gaussian processes (GP) to predict YouTube subscribers and examine category correlations using video data from various topics. The study of correlation matrix analysis was performed with an absolute root mean square error (RMSE) of 26256351, and the NN prediction model outperformed the LR and GP models. The correlation matrix indicates a slight positive correlation of 0.067 among the YouTube categories. Specifically, the correlation coefficients for population, unemployment rate, and urban population are 0.080, -0.012, and 0.082, respectively. These findings suggest future research to create more intentional content and search for significant factors that increase viewership and marketing audience growth
