"The paper presents some early outputs from a study considering Papua’s economic development options. Rich in mineral and forestry wealth, Papua paradoxically suffers the highest levels of poverty in Indonesia; it can be argued that uneven income distribution is as significant as a lack of wealth, or potential. Using secondary data sources the paper looks at how economic development options impact on Papua. However, it concludes that unless Papua resolves its chronic energy shortages economic development will be constrained. Therefore, it considers a number of sustainable energy sources including jatropha and sago and clean technologies: biodiesel, ethanol and anaerobic digestion. An initial cost benefit feasibility study is presented for each option, prior to making some early observations on their economic, social and environmental impact."

"Di Indonesia, energi migas masih menjadi pemasok kebutuhan energi utama dalam negeri. Sebanyak 37,56% Tingkat produksi minyak bumi dalam negeri hanya mencapai angka 746.000 bpd, jauh dibawah kebutuhan energi dalam negeri sebesar 1,8 juta bpd. Sumur produksi minyak di Indonesia telah memasuki usia akhir produksi. Strategi peningkatan pemulihan produksi minyak berupa penerapan teknologi enhanced oil recovery seperti EOR injeksi-CO2, well workover, dan infill drilling telah diajukan. Parameter penelitian difokuskan pada perbandingan peningkatan jumlah produksi lifting produksi minyak bumi terhadap biaya investasi tambahan diperlukan untuk melihat hubungan keekonomian. Hasil penelitian menunjukkan bahwa diperlukan total investasi sebesar US$ 30,61 juta untuk menerapkan ketiga teknologi tersebut sehingga mampu menambah total lifting produksi minyak sebesar 143 bbl/d. Analisis keekonomian menggunakan NPV menghasilkan NPV sebesar US$3,7 juta dengan IRR sebesar 25% untuk penerapan teknologi tersebut. Analisis menggunakan Cox, Ross, Rubinstein (CRR) dan Binomial Lattice menghasilkan valuasi proyek peningkatan kualitas sumur sebesar US$ 25,72 juta dibandingkan dengan metode NPV sebesar US$23,68 juta

In Indonesia, oil and gas energy is still the main supplier of domestic energy needs. As much as 37.56% The level of domestic oil production only reached 746,000 bpd, far below the domestic energy demand of 1.8 million bpd. Oil production wells in Indonesia have entered the final age of production. A strategy to increase oil production recovery in the form of the application of enhanced oil recovery technology such as CO2-injection EOR, well workover, and infill drilling has been proposed. The research parameters are focused on the comparison of the increase in the amount of oil production lifting production against the additional investment costs needed to see the economic relationship. The results showed that a total investment of US$ 30.61 million was required to implement the three technologies so as to increase the total lifting of oil production by 143 bbl/d. The economic analysis using NPV resulted in an NPV of US$3.7 million with an IRR of 25% for the application of the technology. Analysis using Cox, Ross, Rubinstein (CRR) and Binomial Lattice resulted in a project valuation of well quality improvement of US$ 25.72 million compared to the NPV method of US$ 23.68 million."

"Deforestasi merupakan masalah konservasi global, khususnya di hutan tropis. Analisis spasial dan temporal diperlukan untuk menentukan pola dan penyebab deforestasi serta memandu intervensi yang efektif. Pulau Sumatera di Indonesia telah mengalami laju deforestasi tinggi, dan bentang alam Kerinci Seblat menjadi salah satu kawasan hutan terpenting yang tersisa. Penelitian ini menggunakan data pemantauan hutan spasial dan temporal dari dataset European Commission's Tropical Moist Forest, dan data validasi lapangan untuk mengkarakterisasi deforestasi menggunakan sembilan variable prediktor: zonasi di Taman Nasional Kerinci Seblat, deforestasi sekitar, konsesi kehutanan, ketinggian tempat, rute patroli, perhutanan sosial, titik api, jarak dari pemukiman, dan konsesi pertambangan. Data deforestasi historis digunakan pada tahun 1986-2015, dan deforestasi pada tahun 2016-2020 digunakan sebagai variabel respon. Studi ini menggunakan kerangka pemodelan GLM di R dalam menemukan model terbaik untuk proyeksi deforestasi di Lanskap Kerinci Seblat dari tahun 2020 hingga 2045. Hasil penelitian menunjukkan bahwa deforestasi semakin cenderung menurun dan terjadi di dekat aktivitas manusia dan pemukiman. Efektivitas kegiatan patroli dalam mencegah deforestasi menunjukkan perlunya pengerahan sumber daya yang lebih strategis. Perhutanan Sosial, konsesi pertambangan dan kehutanan di sekitar kawasan lindung Taman Nasional Kerinci Seblat berkontribusi signifikan terhadap deforestasi, sehingga menekankan pentingnya praktik berkelanjutan dan intervensi konservasi alam yang lebih luas.

Deforestation is a worldwide conservation problem in tropical forests. Conducting spatial and temporal analysis is necessary to identify the trends and causes of deforestation. Sumatra, an island in Indonesia, experienced significant deforestation, with the Kerinci Seblat landscape being one of the few crucial forests. This study utilizes spatial and temporal forest monitoring data from the Tropical Moist Forest dataset, along with field validation data, to analyze and describe deforestation. The analysis is based on nine predictor variables, namely Kerinci Seblat National Park zonation, deforestation neighbourhood, forestry concessions, altitude, patrol routes, social forestry, fire hotspots, distance from settlements, and mining concessions. The study utilized historical deforestation data from 1986 to 2015, with deforestation from 2016 to 2020 being analyzed as the response variable. This study employs the Generalized Linear Modeling framework in the R programming language to identify the optimal model for predicting deforestation in the Kerinci Seblat Landscape between the years 2020 until 2045. The study findings indicate that deforestation tends to decline and mostly transpires near human activities and communities. The efficacy of patrol operations in forestalling deforestation highlights the necessity for a more strategic allocation of resources. The presence of social forestry, mining, and forestry concessions in the vicinity of Kerinci Seblat National Park has a substantial impact on deforestation. This emphasizes the need for sustainable practices and more comprehensive interventions for environment protection."
