The electric power system is critical to supporting the economic growth of a country. On the other hand, the growing concern about the environment in recent years has pushed many countries to create strategies to minimize greenhouse gas emissions by increasing the proportion of new and renewable energy (NRE) sources. In Indonesia, the Java-Bali power grid is the most extensive electricity system, with a demand of 177,692.43 GWh with a peak load of 40,059.74 MW in 2019. However, the energy mix in Java-Bali is dominated by coal at 70%, followed by natural gas at 21.22%, renewable energy at 7.71%, and fuel at 0.14%. Therefore, there is an urgent need to increase the use of NRE sources in fulfilling the electrical energy demand, with the government setting a renewable energy utilization target of 23% in 2025 and 31% in 2050. This study aims to create a power-generating capacity development planning scenario with the best use of NRE sources at the lowest cost, to support the Indonesian policymakers in obtaining those targets. The Balmoral model with General Algebraic Modeling System (GAMS) programming was used to optimize the planning model for the power generating capacity. The results show that the development planning scenario with a total additional generating capacity of 15,035 MW is the scenario with the most optimal utilization of NRE sources and the lowest cost, with an estimated total investment cost of IDR 901 trillion. Furthermore, this scenario can increase the composition of renewable energy in the Java-Bali system to 16.95% in the next ten years.
Monitoring and supervision of factors that predominantly affect the successful implementation of quality management systems on the project will improve the quality of construction that provides a safety factor in the construction of a pilot plant nuclear fuel processing, to determine those factors is the aim of this research. The separation of Uranium, Thorium, and Rare Earth Metals Pilot Plant was used as a case of the research. Adopted descriptive research design were the primary data collected using questionnaires. Data collected analysed thought multiple linear regressions that only done on factors that have correlation strong – very strong. International Standard Organisation series 9001:2015 and International Atomic Energy Agency safety standards series No. GS-R3 were used as independent variables (X), contamination level was used as dependent variable (Y) that reflected project quality. The result is there are three factors that statistically significant influencing project quality: leadership and commitment, project planning, and safety culture. Those factors influencing the achievement of construction quality of the pilot plant uranium, thorium and rare earth element i.e. 92.3%, while the remaining 7.7% (100-92.3%) is determined by other variables.
Management area of leadership and commitment in the quality management system is a mean to achieve successful functions, even more on construction industry. The objective of this research is to analyze the correlation between leadership and commitment focus management area and quality performance as indicated by rework. Research location is uranium (U), thorium (Th), and rare earth elements (REE) processing pilot plant construction area in Center for Nuclear Minerals Technology-BATAN. Primary data were collected from the 36 of 37 submitted questionnaires, and representing 97 % response rate. The research used descriptive analysis, which depends on the poll and the use of Statistical Package for the Social Sciences (SPSS) main program for data analysis. The relationship between leadership and commitment and quality performance was analyzed using spearman rank correlation coefficient. Findings of research provide guideline and alert to project managers or management of organization where leadership, commitment, infrastructure, and environmental work have moderate to strong correlation to rework level. The results further revealed that there is no relationship between responsibility and authority for the management system and organizational policy and construction quality performance. The research provides evidence, in fact to achieve the quality performance of a pilot plant construction must be concerned with leadership attribute, maintaining commitment and provide support resources on the whole project cycle.Keywords: leadership, commitment, quality performance, construction, U-Th-REE pilot plant ABSTRAKArea manajemen kepemimpinan dan komitmen dalam sistem manajemen mutu adalah sarana untuk mencapai keberhasilan suatu pekerjaan, terlebih pada industri konstruksi. Tujuan dari penelitian ini adalah untuk menganalisis hubungan antara area fokus manajemen kepemimpinan, komitmen, dan kinerja kualitas yang ditunjukkan dengan pengerjaan ulang (rework). Lokasi penelitian adalah area kontruksi pilot plant pengolahan uranium (U), torium (Th), dan unsur logam tanah jarang (LTJ) di Pusat Teknologi Bahan Galian Nuklir-BATAN. Data primer merupakan hasil 36 dari 37 kuisioner yang dikirimkan, dan mewakili tingkat respons 97 %. Penelitian ini menggunakan analisis deskriptif, yang bergantung pada polling dan menggunakan program utama Paket Statistik untuk Ilmu Pengetahuan Sosial (SPSS) untuk analisis data. Hubungan antara kepemimpinan dan komitmen dan kinerja kualitas dianalisis dengan menggunakan koefisien korelasi pemeringkatan spearman. Hasil penelitian memberikan panduan dan peringatan kepada manajer proyek atau manajemen organisasi bahwa kepemimpinan, komitmen, dan infrastruktur serta lingkungan kerja memiliki korelasi menengah hingga sangat kuat terhadap tingkat pengerjaan ulang. Hasil lainnya mengungkapkan bahwa tidak ada hubungan antara tanggung By: Nunik Madyaningarum, et., al. 60 jawab dan wewenang sistem manajemen serta kebijakan organisasi dengan kinerja kualitas konstruksi.

Determining strategic solution for improving quality which has an impact on increasing safety factor is the aim of this research. Therefore, planning on a construction project must be a bridge that links between the process improvement, priorities that support success, and the organization's long-term strategy. This study uses literature study approach that focuses on nuclear facilities and other energy projects which further explain the elements of project planning factors in the construction phase. Brief interviews to experts have been conducted as a validation tool. The main factors for strategic project planning are risk management, modularization, technological uniqueness, project typology and governance.
