Teknesium-99m (99mTc) merupakan radioisotop yang paling banyak digunakan dalam pencitraan medis karena karakteristiknya yang ideal, seperti waktu paruh pendek (6 jam) dan emisi gamma yang sesuai untuk deteksi dengan kamera gamma. Saat ini, 99mTc diproduksi secara konvensional melalui peluruhan Molibdenum-99 (99Mo) yang diperoleh dari reaktor nuklir. Namun, tantangan dalam pasokan 99Mo, masalah limbah radioaktif, serta kekhawatiran terkait proliferasi nuklir mendorong penelitian alternatif produksi 99mTc menggunakan siklotron melalui reaksi nuklir langsung. Studi ini membandingkan kedua metode berdasarkan efisiensi produksi, risiko proliferasi, biaya, dan dampak lingkungan melalui literature review. Hasilnya menunjukkan bahwa produksi berbasis reaktor lebih efisien tetapi memiliki isu limbah, sementara siklotron lebih ramah lingkungan namun masih memiliki tantangan teknis. Hal ini menunjukkan bahwa meskipun produksi 99mTc melalui reaktor masih menjadi metode utama secara global, pengembangan teknologi siklotron menjadi solusi potensial yang dapat meningkatkan keberlanjutan pasokan 99mTc di masa depan. Oleh karena itu, diperlukan penelitian lebih lanjut untuk meningkatkan efisiensi produksi 99mTc menggunakan siklotron agar dapat menjadi alternatif yang lebih kompetitif.

This research examines the influence of effective communication on the success of lobbying and negotiation. Lobbying and negotiation, although differing in their approaches (lobbying is one-way persuasive, negotiation is interactive and involves bargaining), both aim to influence decisions or reach agreements. The success of both heavily relies on effective communication, which includes building relationships, understanding the interlocutor, and overcoming communication barriers. Effective communication strategies involve thorough planning, persuasive communication, conflict management, and understanding the context and interests of all parties. Literature studies show that effective communication is a key success factor, building trust, delivering persuasive messages, managing conflicts, building consensus, and understanding the needs of other parties. Persuasive, assertive, and nonverbal communication also play a crucial role in reaching mutually beneficial agreements. In conclusion, effective communication increases the chances of successful lobbying and negotiation.

This study aims to analyze the impact of online learning on students' learning independence at the secondary school level. The research is motivated by the significant shift in the education system due to the pandemic, which required students to adapt to technology-based distance learning. A descriptive qualitative approach was employed, utilizing data collection techniques such as observation, interviews, and documentation, supported by quantitative questionnaires from previous studies. The findings indicate that online learning has both positive and negative effects on students' learning independence. Positive impacts include increased student responsibility in completing assignments, ease of accessing learning materials anytime and anywhere, and enhanced parental involvement in supporting their children's learning at home. However, negative effects were also identified, such as students' tendency to engage excessively in gaming, reduced effectiveness of the learning process, and delays in task submission due to workload accumulation. Regression analysis results show a significant influence between online learning and learning independence, although the effect is moderate to low in some cases. Factors such as learning motivation, self-efficacy, and the support of the online learning environment play crucial roles in shaping student independence. The study recommends collaboration among government, schools, teachers, parents, and the wider community to improve the quality and quantity of online learning facilities, as well as more varied learning strategies to optimally support the development of students' learning independence.

The integration between industry and other sectors such as agriculture, services, trade, and labor proves essential in strengthening competitiveness and achieving inclusive growth. Findings indicate that despite its potential, industrialization in Indonesia still faces challenges such as import dependency, limited skilled labor, and regional disparities. Therefore, future industrial strategies should focus on enhancing sectoral linkages, promoting equitable development, and improving human capital and infrastructure capacity to support sustainable economic growth.

One of the negative impacts of the mining process is acid mine drainage which is formed from the oxidation of minerals containing iron sulfur, such as pyrite (FeS2) and pyrothite (FeS) by oxidizers such as water and oxygen. To handle or control acid mine drainage, one way is to use activated carbon or often referred to as activated charcoal, which is a type of carbon that has a very large surface area. Charcoal is a porous solid that contains 85% to 95% carbon, produced from materials containing carbon by heating at high temperatures without oxygen (pyrolysis). Activated carbon made from palm shells is an adsorbent that can be used to treat coal mine acid water, so that the water meets standards for flowing into the environment. This study used concentration variants of 4 grams, 6 grams, 8 grams and contact times of 30 minutes, 60 minutes and 150 minutes. The results of this study show that the concentration of palm oil shell activated carbon adsorbent influences the reduction of iron (Fe) and manganese (Mn) metal levels as well as the pH conditions in acid mine drainage water. The higher the concentration and the longer the contact time, the more heavy metals are adsorbed, the contact time is the highest. The optimal concentration in this study was 150 minutes and the optimal concentration was 8 grams with physical activation.

Settlement is a basic human need that is closely related to the feasibility of life and well-being. The purpose of this study is to gain a better understanding of settlement patterns that occur in rural and urban areas, and to investigate the factors that influence these patterns. This study collects, analyzes, and synthesizes related literature. The results show that settlement patterns in urban areas are denser and develop vertically, while settlement patterns in rural areas tend to be spread out and horizontal. Various factors, such as natural conditions (such as climate, topography, water and land availability), socio-economic factors (such as employment, education, and income), and government policies and local cultural developments, influence these differences. These results emphasize that understanding settlement patterns as a whole is essential to building areas that are equitable, sustainable, and responsive to community needs.
