Durability is defined as a measure of a rock's resistance to weathering and disintegration when the rock undergoes weathering processes over a short period of time. The susceptibility of rocks to disintegration is related to their low durability. Rock durability is often measured using the slake durability test. The slake durability test is widely used to assess physical changes resulting from wetting-drying processes (Franklin and Chandra, 1972). Therefore, slake durability testing is conducted to understand the weathering of rocks caused by heat and water, particularly clay stones which are one of the constituent rocks on a slope. The sampling location is around Sanga-sanga and Muara Badak. Sampling was conducted with coordinate points and the Balikpapan and Kampungbaru formations. The claystone samples taken were then brought to the Mineral and Coal Technology Laboratory of the Engineering Faculty of Mulawarman University for Slake Durability tests. In this study, the lowest index value obtained was 45.7% and the highest value was 93%, indicating high to very high durability. The difference in the durability index values of claystone at the research locations indicates the presence of variables that can affect the slake durability index values of the claystone in the Balikpapan and Kampungbaru formations, including grain size and mineral content as well as geological conditions at the research site. Based on the results of the claystone durability tests, the durability index value (Id2) was obtained, indicating that the sandstone at the research location falls into the classification of high to low.

Indonesian people love to consume bananas as fruit. Many sources of nutrients, including minerals and carbohydrates, are contained in this fruit. Various UMKM (Usaha Mikro, Kecil dan Menengah) have grown by developing processed banana foods such as sale and banana chips. An important step in making processed banana dishes is cutting the bananas. In general UMKM still process bananas using conventional techniques, namely cutting using manual human power. The purpose of this study is to utilize gravity to design a banana cutting machine. Gravity will cause the banana pieces to fall into the storage container. The dimensions of the cutting machine are designed with a small size to facilitate mobility. The results showed that the use of a cutting machine increased the efficiency of banana cutting. A more uniform cutting thickness was achieved.

Stunting remains one of the major nutritional problems in Indonesia. According to the 2024 Indonesian Health Survey (SKI), the prevalence of stunting in Papua Province reached 16.8%. A child’s nutritional status is strongly influenced by dietary intake, particularly protein, which plays a crucial role in growth. One potential source of animal protein is Indian mackerel (Rastrelliger kanagurta), a type of fish commonly found in Papua. Indian mackerel is rich in protein and omega-3 fatty acids but is highly perishable, limiting its shelf life. To address this issue, the fish is processed into flour. Additionally, green spinach is used as a source of fiber and minerals, although it is also prone to spoilage. The spinach is processed by extracting its juice, which is then incorporated into noodle products. Dried noodles were chosen as a medium for fortification because they are widely consumed across age groups and often used as a substitute for rice.This study aimed to determine the effect of adding Indian mackerel flour and green spinach extract on the chemical properties and sensory acceptance of dried noodles. The research methods included nutritional content analysis and organoleptic testing. The sensory evaluation was conducted by 25 semi-trained panelists who were nutrition science students

This article examines the shift in local government authority over mineral and coal mining management following the enactment of Law Number 23 of 2014 on Regional Government. The transfer of authority from regency/city governments to provincial and central governments has created normative disharmony between the Regional Government Law and the Mining Law, resulting in legal uncertainty at the implementation level. Using a normative juridical approach and Hans Kelsen’s theory of the hierarchy of norms, this article analyzes the legal validity of the transfer and identifies structural conflicts within the legal system. The findings indicate that the current regulation lacks both hierarchical consistency and functional clarity. Therefore, a reconstruction of the legal framework for mining governance is required to balance the principle of legality with the concept of regional autonomy. A model of limited delegation, sectoral regulatory harmonization, and the application of multilevel governance are proposed as key recommendations to ensure a fair, effective, and constitutional relationship between central and local governments.  

This community service program aimed to enhance nutritional awareness and increase milkfish consumption through the innovation of a traditional dish, pepes ikan bandeng, in RT 31, Sebengkok Subdistrict, Tarakan City. Although milkfish is rich in nutrients such as protein, omega-3 fatty acids, vitamins, and minerals, its consumption remains low due to the presence of numerous fine bones. The program adopted a hands-on approach involving community members in every step of the process, including ingredient preparation, cooking, and product distribution. The results demonstrated that pepes ikan bandeng, traditionally seasoned and wrapped in banana leaves, not only offers a unique and appetizing flavor but also retains its nutritional value. This activity successfully educated the community on the benefits of consuming nutritious local fish while preserving traditional culinary heritage as a means of community empowerment.

Coal is an organic mineral from ancient plant remains that settles and goes through physical or chemical processes over a period of up to millions of years. Coal is used as a source of steam-powered electrical energy through combustion which produces fly ash waste. fly ash contains various chemical materials such as SiO2; Al2O3; Fe2O3. The potential chemical content makes fly ash which can be used as an adsorbent for heavy metals and dyes by forming silica xerogel. To increase the silica oxide content in fly ash, a washing process is carried out with various solvents. Research on the adsorption of methylene blue dye using silica xerogel from fly ash with variations in contact time. The results showed that silica xerogel from fly ash was able to adsorb methylene blue dye at a contact time of 90 minutes. Adsorption kinetics follows a pseudo second order model with an R2 value that is better than pseudo first order. It can be seen that the R2 value respectively shows a linear regression of 0.703 for pseudo first order and 1 for pseudo second order.

Instant noodles, categorized as part of ready-to-eat cuisine, represent a form of food that is conveniently packaged, easily served, practical, and prepared in a straightforward manner. Despite their convenience, instant noodles fall short of being considered a comprehensive food option due to their inability to fulfill the body's well-rounded nutritional requirements. A typical serving of instant noodles primarily consists of elevated levels of carbohydrates and protein, yet lacks sufficient energy, fiber, vitamins, and minerals. The consumption of instant noodles is driven by the time constraints faced by a majority of consumers, preventing them from indulging in a complete meal and preparing it from scratch. Regularly consuming instant noodles may pose health risks and hazards, given their inclusion of preservatives and low nutritional content. This study employs quantitative research methods, adhering to scientific principles by being concrete, empirical, objective, measurable, rational, and systematic. Quantitative approaches prioritize the analysis of numerical data, subsequently processed through suitable statistical methods. In conclusion, the statistical analysis conducted reveals that both preference (X1) and suitability (X2) jointly exert a significant impact on packaging quality (Y) within the scope of this research. However, it is crucial to note that 51.1% of the variation in Y remains unexplained by these two independent variables, suggesting that other factors may also contribute to determining the quality of packaging.  

This study was conducted to implement the law on the case of illegal mining carried out by Chen Fu as a perpetrator of a criminal act in the Mining Business Permit (IUP) area of ​​PT ANTAM Tbk UBPN North Konawe, and to assess whether its implementation has accommodated ecological justice based on Law Number 3 of 2020 concerning Mineral and Coal Mining (Minerba Law) and Law Number 32 of 2009 concerning Environmental Protection and Management (PPLH Law). The method used in this is normative-doctrinal with a statutory approach and a case approach. Thus, the results of the study show that the legal approach in this case is still limited to the administrative aspect and does not substantially reflect ecological justice. There is a need for harmony between the Minerba Law and the PPLH Law in their implementation to reach aspects of ecological losses, strengthen the deterrent effect, and pave the way for comprehensive environmental recovery. The resulting research recommendations explain the importance of reforming charges in illegal mining cases that cause environmental damage, so that the law can be enforced fairly, comprehensively, and with a sustainable perspective.
