Fried anchovy (Stolephorussp.) is a popular food in Indonesia due to its good taste and ampleavailability and affordability. Yet, the actual nutritional aspects of this local dish remain uninvestigated.This study aimed to determine the best temperature and time for frying anchovies and to compare thehistology and fatty acid and cholesterol profiles of fresh and fried anchovy meat. Anchovies werefried at 160°C or 180°C for 5, 10, 15, and 20 minutes, and the best frying conditions, namely at180°C for 15 minutes, were established from the highest organoleptic test scores from a tasting panelassessment. Histologically, fried anchovy meat became shrunk, compact, and brittle, as explainedby identified myomere changes. The fatty acid profile of fresh vs. fried anchovies revealed a markedreversal in omega-6: omega-3 ratios, and fried anchovies contained more cholesterol than fresh ones(0.825 mg/100 gvs. 0.270 mg/100 g, respectively). These changes were triggered by the use of oiland the temperature-driven chemical changes inherent to the frying process. Having investigated theorganoleptic and nutritional aspects of frying anchovy meat, we propose the results of this investigationas a guide for dietary decisions and as a reference for further investigation on the subject.

Trypsin production from skipjack tuna (Katsuwonus pelamis) viscera is one significant way to increase the value of fish’s industrial waste. The present work reports the biochemical properties of trypsin from skipjack tuna viscera. The trypsin was fractionated using 0–60% ammonium sulfate and dialyzed. The enzyme was characterized to find the optimum temperature and pH for the substrate N-α-benzoyl-dl-arginine-p-nitroanilide. The 40–50% ammonium sulfate fractionation showed the highest activity at a specific activity of 1.66 U/mg and yield of 69.91%. Specific activity increased after dialysis to 2.17 U/mg with 4.49 times purity and yield of 39.20%. The molecular weights of the enzymes were estimated as 25, 29, and 35 kDa based on the enzyme activity separated by electrophoresis. The enzyme worked optimally at a temperature and pH of 50–60°C and 8.0, respectively. Metal ions (Ca2+, K+, Na+, Mg2+) at a concentration of 20 mM showed no influence on the activity. Enzyme activity was inhibited by Zn2+ at 20 mM, phenyl methyl sulfonyl fluoride (PMSF), benzamidine, and soybean trypsin inhibitor (SBTI), which confirmed the characteristics of a serine protease.

Seaweed contains various bioactive compounds rich in pharmacological potentials, such as antioxidants and anti-arthritic. This study aims to determine the antioxidant and anti-arthritic activities of the methanolic extract of Halimeda tuna. Halimeda tuna samples were extracted using the maceration method and methanol. The methanol extract was tested for antioxidant (2,2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP)) and anti-arthritic activity using denatured bovine serum albumin (BSA). The methanol extract was also subjected to phytochemical and Gas Chromatography-Mass Spectrometry (GC-MS) analysis. Research results revealed that the extract yield was 0.50 ± 0.06%. Phytochemical analysis showed that H. tuna methanolic extract contained flavonoids, steroids, and alkaloids. GC-MS analysis showed that H. tuna methanolic extract contained steroids, fatty alcohols, and fatty acids. The antioxidant activity tests revealed an IC50 value of 299.98 ± 121.15 ppm and a FRAP value of 200.02 ± 8.50 M/g, categorized as a weak antioxidant. Anti-arthritic activity of H. tuna methanolic extract showed an IC50 value of 877.29 ± 209.84 ppm. The anti-arthritic activity of H. tuna methanolic extract was lower than sodium diclofenac as a standard drug. The extract of H. tuna has antioxidant and anti-arthritic activities; hence, further exploration is needed as an alternative potential in the pharmacological field.

Healthy seaweed salt is low sodium salt from seaweed that offers health benefits for hypertension patients. Indonesian seaweed has the potential to produce healthy seaweed salt. Research to date still focuses on green and brown seaweed but there is still no report for red seaweed. Actinotrichia fragilis is one of red seaweed species that has been discovered in Indonesia’s seawater and has not yet been utilized. Thus, this study aimed to determine the chemical composition and antioxidant activity of A. fragilis flour and the optimum ratio for producing seaweed salt with a high yield, optimum %NaCl, Na/K ratio, and antioxidant activity. Seaweed salt production treatment was the ratio of seaweed flour and distilled water 1:3, 1:5, and 1:10 (w/v), extracted at 40°C for 10 minutes. The mixture was filtered, then dried at 60°C for 30 hours. Data analysis was performed by analysis of variance. The raw material for dried A. fragilis seaweed has a high ash and low-lipid content. Then the ethanol extract had a total phenolic content value of 84.34 mg GAE/g and an antioxidant activity value of 98.22 mg/L. Furthermore, the antioxidant capacity of the ethanol extract was 60.15 mmol ascorbic acid/g and 552.21 mmol Fe2+/g. The best treatment for producing A. fragilis salt is 1:10 with yield of 12.76±0.13%, %NaCl 47.22±1.38%, Na/K ratio 3.32±0.18, IC50 with DPPH and ABTS method 113 mg/L and 87.27 mg/L, total antioxidant capacity 38.21 mg/mL ascorbic acid/g, and 304.32 mmol Fe2+/g. Furthermore, A. fragilis can be used for the production of healthy seaweed salt.

Indonesian shortfin eel (Anguilla bicolor bicolor) is a high economic value fish and a high nutritional content. However, their utilization can be limited because of hypersensitivity cases in individuals allergic to fish. This study aimed to determine the characteristics of the fish major allergenic protein, parvalbumin in different parts of the eel fillet and the effects of boiling technique on the content of this protein. The samples were boiled with 100 mL of water in an Erlenmeyer flask at 95°C for 10 min. The eel fillet was divided into three parts: the front, middle, and rear part of the body. Protein profiles from each part were identified using sodium dodecyl sulfate-polyacrylamide gel electrophoresis and Bradford assays. Parvalbumin was further purified by ammonium sulfate precipitation. The concentration of protein in the different parts of the eel was not significantly different, whereas the processing treatments (meat with water (F1 extract) and meat without water (F2 extract)) affected protein concentration. Eel meat contained proteins with molecular weights ranging from 10 to 186 kDa. Parvalbumins are highly water-soluble, as their content was reduced in the fillet, but were observed at a high concentration in the water after boiling. Parvalbumins of eel were purified by ammonium sulfate 70-90% with high purity. Interestingly, two different bands were observed in SDS-PAGE, suggesting the presence of a protein variant. The molecular weight of parvalbumin obtained from purification ranged from 10 to 11 kDa, similar to that of other fish.

This article aims to describe the views and arguments of NU scholars in responding to the concept of istibdâl waqf through the fatwas issued by Lajnah Bahtsul Masail (LBM-NU), and their relevance to Islamic law reform. The concept of istibdâl is basically one way that can be used by policy makers in managing waqf land so that it remains productive. However, the concept of istibdâl has not been fully accepted by scholars. In general, the responses of scholars regarding the concept of istibdâl can be grouped into two. The first group strictly prohibits istibdâl, and the second group allows istibdâl but with strict conditions. The difference is more due to the tendency of the principle that is the weight, namely the principle of eternity (ta’bid al-ashl) and the principle of expediency (tasbîl al-manfa’ah). This research is a normative legal research because it examines the legal provisions, arguments and arguments used. The approach used is a conceptual approach. Primary data sources are fatwa texts issued by NU scholars, while secondary data sources are scientific books, articles, journals, laws related to this research. This study shows that NU scholars allow the practice of istibdâl with agreed terms, namely the existence of disadvantages contained in the waqf object so that the waqf property is in an emergency condition that must be saved. The argument is that the concept of benefit is the spirit of maqâshid syari’ah (the purpose of syari’a), where the value of benefit in istibdâl practice is far greater than its harm. The concept of benefit which is the argument in the fatwa is in accordance with the spirit of reforming Islamic law.

Indonesia has thousands of islands. However, many islands are threatened with sinking due to rising sea levels and abrasion. This research aims to explain environmental communication based on tourism management to mitigate abrasion on Bengkalis Island. The research method used was a qualitative approach with case studies. The results show that the Coordinating Ministry for Maritime Affairs and Investment together with other ministries, regional governments and experts collaborated to communicate to overcome the abrasion problem on Bengkalis Island. To mitigate abrasion, the government is building breakwaters, rehabilitating mangroves, and creating communication programs. The government’s environmental communications involve the NGO Malay Youth Association that Cares for the Environment (IPMPL) to deal with abrasion, as was done at Raja Kecik Beach. This community-based tourism was built as a means of government communication to campaign for the protection of the coast of Bengkalis Island. The development of marine tourism that is integrated with the prevention of environmental damage not only contributes to the economy and community welfare but also contributes to environmental sustainability. Communication based on tourism management has not been managed well. Therefore, the government must involve other stakeholders for sustainable development in the context of mitigating abrasion disasters.

The integration of natural additives, such as Spirulina platensis, to elevate the nutritional profile of snack bars represents a novel and ambitious initiative. This study delves into the innovative realm of edible coating for spirulina snack bars using maltodextrin and gelatin. The investigation explores the correlation between total phenol content and antioxidant activity through the FRAP method, employing two solvents, methanol, and n-hexane. Results demonstrate that varying concentrations of edible coating significantly enhance the appearance and texture of Spirulina Snack Bars (SSB). Notably, the SSB coated with 6% maltodextrin and 1% gelatin exhibits superior visual appeal and a firmer texture compared to its counterpart coated with 3% maltodextrin and 1% gelatin. Moreover, the n-hexane extract showcases higher antioxidant activity (19.971 mg/g) than the methanol extract (16.400 mg/g). This study underscores the effectiveness of n-hexane-based edible coatings in elevating the antioxidant potential and total phenol content of spirulina snack bars, offering essential insights for the development of functional foods with enhanced nutrition and prolonged shelf life.

Cirebon Regency is in West Java Province and it’s one of the largest rice producer in Indonesia so that Cirebon Regency has a rice surplus. West Java is included as a region with access rice availability and the source of rice comes from within the West Java region itself, so there is minimal intervention from other regions in terms of meeting rice needs. In an effort to maintain rice resilience, strategies that can be implemented by West Java Province include maximizing the availability of rice in the region to meet local needs, distributing part of its production to surrounding deficit areas, and maintaining the productivity of rice fields. The results of the review literature, food security were not realized in Cirebon Regency because exports and imports of rice production were not properly recorded, distribution of rice production was not monitored, supply stability and price affordability were not controlled, access and information to markets are limited.. The regional government is implementing an agricultural intensification policy, especially in cultivating rice considering that the amount of agricultural land is decreasing, but behind the success there is the potential for climate change which could cause a decrease in productivity. In order to support sustainable food security in Cirebon Regency, it is necessary to analyzed the availability and distribution patterns of rice from upstream to downstream. This pattern is expected to answer the uncertainty of rice availability in Cirebon Regency and its relationship in supporting food sustainability in the future. The method that will be used to answer this problem is to carry out primary data analysis at the rice mill level in Cirebon Regency. Apart from that, the rate of land conversion as a factor influencing rice production is used as analysis material for recommendations for the sustainability of food availability in Cirebon Regency. Food security and sustainability efforts can be achieved with policy changes and transformation of food system governance.

Spirulina, renowned for its impressive protein content of 55-70% of dry weight, surpasses commonly used plant sources like soybeans, peanuts, or cereals. However, Spirulina snack bars, with their inherent texture, may face challenges like moisture absorption and microbial growth. In this context, edible coatings emerge as a solution to prevent moisture ingress, microbial growth, and preserve the bars. This study delves into analyzing the protein content of edible coatings, specifically maltodextrin with a 6% concentration and 1% gelatin, aiming to assess their efficacy in safeguarding against ambient moisture and oxygen. The findings reveal that the snack bar with the specified coating concentration showcases enhanced visual appeal and a denser texture. Protein analysis using SDS PAGE identifies bands with molecular weights of 17kDa, 25kDa, and 35kDa, likely corresponding to αs-CN and β-CN proteins. Chromatogram analysis of the Spirulina snack bar using the HPX-87H column unveils a peak at 6.195 minutes in the methanol extract, indicating abundance in α-tocopherol, a vitamin E variant. This comprehensive exploration underscores the potential of edible coatings, providing insights into their role in preserving Spirulina snack bars and contributing to food industry advancements.

Starch-based bio-foam material, as an alternative to styrofoam, has shortcomings in mechanical properties and water resistance, so it needs a filler in the form of cellulose fibre, which is insoluble in water and has strong properties. It has been studied that nanoscale fibres have an excellent mechanical property. This study aims to determine the effect of adding cellulose fibre and cellulose nanofiber (CNF) from bagasse on the characteristics of biofoam made of avocado seed starch. The manufacture of biofoam is conducted over the thermopressing method. The added cellulose fibres varied from 0%, 1%, 3%, and 5% w/w, and cellulose nanofibers ranged from 3%, 5%, 10%, 15%, and 20% w/w by weight of starch The results of testing biofoam from two different types of fillers showed that adding 5% of both fillers produced biofoam with the most excellent properties. Biofoam with 5% cellulose fibres from bagasse has a tensile strength value of 382.32 KPa, a water absorption capacity of 11.08%, and can degrade 10.94% in a specified time of 8 days. Adding 5% CNF from bagasse produced biofoam with a tensile strength of 385.02 Kpa, water absorption of 5.96%, and biodegradability value of 17.74% within eight days. It can be summarised that nanoscale fibres can increase the water resistance, mechanical properties, and biodegradability value of biofoam made with avocado seed starch.

Indonesia is located in a very strategic position between the continents of Asia and the continent of Australia and the Pacific Ocean and the Indian Ocean, which makes Indonesia a sea line of communication (SLOC) and sea trade route (Sea Lines of Trade / SLOT) for the international world. The size of the Indonesian Navy (TNI AL) territory carried out with the potential threats faced is still not comparable. In order to secure the border areas and maintain the country’s sovereignty, President Joko Widodo intends to build the islands of Natuna, Bitung, and Selaru as Aircraft carriers. The Navy can support this desire by strengthening the Naval Bases located in the three regions. Strengthening the Naval Base can be done by analyzing the essential functions and duties of the base and the general requirements of the base. Furthermore, an analysis of the capabilities and technology of weapons owned by the Aircraft carriers of countries in the world can be used as a reference for constructing Indonesian Aircraft carriers. In addition, an analysis of the Naval Base from the Naval Base and Naval Home Base levels is the most appropriate for strengthening to increase the country’s deterrence and defense at sea. From the analysis results, three selected Naval bases were determined, namely: Naval Base Ranai, Naval Home Base VIII Manado, and Naval Base Saumlaki.

Indonesia is the 7th largest country in the world with a very strategic location between the continents of Asia and the continents of Australia and the Pacific Ocean and the Indian Ocean. This condition provides an advantage as well as a vulnerability to the sovereignty of the Indonesian state. This has an impact on the task of the Indonesian Navy (TNI AL) in maintaining state sovereignty and enforcing the law in Indonesia's jurisdictional seas. In carrying out this task, the Indonesian Navy is experiencing obstacles because the vast field of work and potential threats to state sovereignty that exist today are not comparable to the conditions of the Main Weapon System Equipment (Alutsista) owned, so it is necessary to develop a Navy Base that can function as a carrier for strong national defense. Writing this article aims to determine the right strategy by analyzing the strengths and weaknesses of the Indonesian Navy in the face of existing opportunities and threats. From this analysis, a strategy can be determined to develop the Indonesian Navy Base as an aircraft carrier. Of the four strategies produced, the best strategy to implement is to develop the Indonesian Navy Base as an aircraft carrier with the support of the central government and local governments as well as high-ranking of Indonesian armed force/Indonesian Navy officials to realize state defense policies and the mandate of the law to improve national defense to maintain national security, territory and sovereignty of the Republic of Indonesia.

This study aims to explain the corporate communication of state oil companies through CSR in contributing to overcoming the problems of peatland fires and coastal abrasion. This research uses a qualitative approach with case studies. Research findings indicate that Pertamina’s CSR communication targets farmer groups in dealing with peatland fires, namely establishing good relations, strengthening farmer group institutions, and connecting with other stakeholders or groups. Meanwhile, to overcome coastal abrasion, Pertamina empowers fishing groups in meetings, provides training and develops innovations to conserve mangroves. CSR communication to overcome the problem of forest fires and abrasion is carried out by developing ecotourism through community-based tourism (CBT). CSR activities are carried out with a limited area scale, so that it seems only for publication and corporate imagery. However, the company’s communication with CBT can be an effective communication model in making people aware of protecting the environment. The Peat Arboretum and Mangrove Education Center are not only tourist destinations, but also a medium of communication for environmental education for the community. Environmental communication is not only directed to the local community, school students, and youth, but also to visitors, for media coverage and discussions on social media. Corporate environmental communications must be integrated with communication channels and stakeholders to support sustainable environmental development.

Employment is one of the important factors in national development. This study aims to analyze the employment conditions of North Kalimantan Province, from the workforce to the unemployment rate. The average LFPR (Labour Force Participation Rate) in North Kalimantan Province in 2020 is 66.51. Especially in the district which has many coal and mineral industries, the initial LFPR was 75.04 in Malinau Regency. Kalimantan Province's EPR based on age group shows that in 2018, 2019, and 2020 there are not too many differences in EPR (Employment to Population Ratio) levels. The lowest EPR is always in the 15-19 age group with an EPR of 22.94%; 17.95%; and 24.73%. Tarakan City has a higher TPT (Open Unemployment Rate) value than other districts, even compared to North Kalimantan Province with 5.89%, 5.3%, 5.86%, and 4.14%. North Kalimantan experienced a decrease in the underemployment rate of 0.37% in 2018—2019. Then in 2020, all districts/cities in North Kalimantan experienced an increase in the underemployment rate.

The study aims to analyze the role of e-mentoring in developing leadership skills between mentors and mentees, particularly in global environment. This research is using qualitative approach that work on a comprehensive literature development on e-mentoring platform for future leaders. The COVID-19 pandemic has disrupted the labour market, making it difficult for young people to secure productive employment. They often lack experience, talents, and social networks, making it difficult to find suitable candidates. Informational asymmetry and limited access to resources further exacerbate these employment obstacles. A significant proportion of youth are not employed, in school, or training, resulting in diminished employment prospects and challenges in adapting to the workplace. The result shown that e-mentoring offers numerous advantages, including accessibility, professional development, and enhanced communication skills. It allows mentees to ask questions anytime, anywhere, and can be used for professional growth. E-mentoring also improves teamwork and accessibility, allowing for diverse collaboration and breaking down sociocultural barriers. However, it also presents challenges, such as ensuring proper communication and addressing cultural differences. Overall, e-mentoring offers a more accessible and effective mentoring system.

Seaweed belongs to marine biota and contains nutrients and secondary metabolites beneficial for health. This study aimed to determine the antidiabetic activity of extracts and fractions of green seaweed Halimeda tuna. The H. tuna sample was extracted with the maceration method using methanol and then partitioned using ethyl acetate and water to obtain ethyl acetate and water fractions. The methanol extract, ethyl acetate fraction, and water fraction of H. tuna were tested for their inhibitory activity against α-amilase and α-glucosidase. The methanol extract and the fractions with the highest inhibitory activity were phytochemically tested and analyzed using gas chromatography–mass spectrometry (GC-MS). The results showed that the ethyl acetate fraction (IC50 = 0.88 ± 0.20 mg/mL) inhibited α-amylase relatively similar to acarbose (IC50 = 0.76 ± 0.04 mg/mL). The methanol extract (IC50 = 0.05 ± 0.01 mg/mL) and the ethyl acetate fraction (IC50 = 0.01 ± 0.00 mg/mL) demonstrated stronger inhibitory activity against α-glucosidase than acarbose (IC50 = 0.27 ± 0.13 mg/mL). Phytochemical testing showed that the methanol extract and the ethyl acetate fraction contained secondary metabolites: alkaloids, flavonoids, steroids, and phenol hydroquinone. The compounds in methanol extract predicted to have inhibitory activity against α-amylase and α-glucosidase were Docosanol, Neophytadiene, Stigmasta-7,22-dien-3-ol,acetate,(3.beta.,5.alpha.,22E), Octadecanoic acid,2-oxo-,methyl ester, and phytol, while those in the ethyl acetate fraction were n-Nonadecane, Phytol, Butyl ester, 14-.Beta.-H-pregna, Octadecenoic acid, and Oleic acid.
