Nugget is a high protein frozen food. Catfish is one of the raw materials that can be used to make nugget Catfish contains high protein, tastes good, has a soft texture and is relatively cheap. To increase the nutritional content, vegetables are added in the processing. Broccoli is one of the vegetables that can be added in making nuggets because contains high fiber and potassium. The purpose of this study was to determine the effect of adding broccoli with different concentrations on the crude fiber, potassium and organoleptic values of catfish nuggets. The research design used was a completely randomized design with 4 treatments, each with 3 replications. The treatment in this study was based on the concentration of broccoli added, namely B0 (0%), B1 (25%), B2 (50%) and B3 (75%). Parameters observed were crude fiber, potassium, and organoleptic value of catfish nuggets. The results showed that the addition of broccoli at various concentrations had a significant effect (P<0.05) on crude fiber, and potassium value but had no significant effect on organoleptic values. The most preferred nuggets with the addition of broccoli was treatment B1 (25%). The addition of broccoli in the processing of catfish nuggets can increase crude fiber and potassium.

Sandwich composites are lightweight structural materials with a high strength-to-weight ratio and have potential as alternatives to conventional materials. This study aims to analyze the effects of core thickness variation and the number of skin layers on the bending strength of fiberglass-skinned sandwich composites with an A-flute cardboard honeycomb core. The research employed an experimental method using three-point bending tests in accordance with ASTM C393. Core thicknesses of 10 mm, 20 mm, and 30 mm were investigated, while the number of fiberglass skin layers was varied at 1, 2, and 4 layers. Bending strength was evaluated based on core shear strength and skin bending stress, expressed in MPa. The results show that the highest average core shear strength was obtained at a core thickness of 10 mm with 4 skin layers, while the lowest value occurred at a core thickness of 30 mm with 1 skin layer. The highest skin bending stress of 43.40 MPa was achieved by the specimen with a 10 mm core thickness and 1 skin layer, whereas the lowest value of 11.83 MPa was observed at a 30 mm core thickness with 4 skin layers. These results indicate that increasing core thickness tends to reduce bending strength based on core shear strength, while increasing the number of skin layers enhances the bending performance of the sandwich composite, and an interaction effect between the two variables is present.

The development and performance of high-strength, environmentally friendly, and renewable nunang fiber (Cordia dichotoma)-reinforced polyester composites continue to be refined to achieve optimal performance. This study characterizes the key properties of nunang fiber-reinforced polyester composites with carbon powder fillers. The polyester composites were fabricated using a hot-press method with a nunang fiber volume fraction of 20% (by weight) and varying carbon powder content from 0–10% (by weight). The results of the investigation show that the tensile and bending strengths of the composites increase with increasing carbon powder content up to 2.5%. However, adding carbon powder filler up to 10% to the polyester–nunang fiber composites reduces their tensile and bending strengths. A different trend is observed for the impact toughness of the composites, which increases up to a carbon powder content of 5% and decreases when the carbon powder content reaches 10%. This phenomenon is attributed to the ability to form an optimal fiber-matrix interface between the nunang fibers and the polyester–carbon powder matrix. SEM morphological observations confirmed fiber pull-out failure and matrix failure due to the high stiffness caused by the presence of the carbon powder filler.

The physiological changes that occur during pregnancy, both physically and mentally, may be rather uncomfortable, particularly in the second and third trimesters. Pregnant women often report back discomfort, muscular aches, trouble sleeping, excessive exhaustion, and irregular sleep patterns. Mothers' physical and mental health as well as the health of their unborn children may be significantly impacted by inadequate sleep quality during pregnancy. To enhance comfort and the quality of sleep during pregnancy, one non-pharmacological technique is to use an aromatherapy maternity pillow. An ergonomic and ecologically sustainable invention to enhance mother comfort during pregnancy was the goal of this research, which intended to produce a Pregnancy Pillow Therapy product with pineapple leaf fiber and aromatherapy. A descriptive research design using a prototype creation technique was used in this study. The stages of the research included problem identification, literature review, product design, material selection, prototype manufacturing, and product evaluation. Data were collected through literature studies and observations related to sleep discomfort in pregnancy, maternity pillow utilization, aromatherapy therapy, and pineapple leaf fiber characteristics. The developed product was designed ergonomically to support the back, abdomen, waist, and legs of pregnant women. The addition of aromatherapy was intended to provide a relaxing effect and improve sleep quality. The use of pineapple leaf fiber also supports environmentally friendly product innovation through agricultural waste utilization. The results indicate that Pregnancy Pillow Therapy has the potential to become a supportive product for improving comfort and sleep quality among pregnant women. Further studies are recommended to evaluate product effectiveness directly among pregnant women.

Based on the 2023 Indonesian Health Survey, the prevalence of overweight among adults reached 23.4% nationally and 24.5% in East Java Province. This condition highlights the need for food innovation, particularly high-fiber snacks suitable for overweight adults. This study aimed to develop cereal based on okara (soy pulp) flour and mung bean flour as an alternative high-fiber food product. Organoleptic testing was conducted on 30 semi-trained panelists evaluating color, aroma, texture, and taste using hedonic and hedonic quality tests. Data were analyzed using the Kruskal–Wallis test followed by the Mann–Whitney test, while nutrient content analysis was analyzed using One Way ANOVA followed by Duncan’s post hoc test. The results showed that in the hedonic test, color, texture, and taste parameters were significantly different (p<0.05), while aroma was not significantly different (p>0.05). In the hedonic quality test, color and taste showed significant differences (p<0.05), whereas aroma and texture did not (p>0.05). Overall, formulation 922 was the most preferred by panelists. The nutritional content of the cereal ranged from 407–410 kcal for energy, 76.44–77.53% carbohydrates, 8.91–9.66% protein, 6.80–7.30% fat, 5.20–5.51% moisture, 1.26–1.41% ash, and 9.72–10.90% total dietary fiber. The developed cereal is classified as a high-fiber food and has potential as a healthy snack for overweight adults.

High feed costs remain a major constraint in Nile tilapia (Oreochromis niloticus) aquaculture, requiring alternative feed formulations based on local ingredients with adequate nutritional quality. This study aimed to evaluate the proximate composition of fish feed formulated from snail meal, Azolla meal, and turmeric as a phytobiotic supplement. The study used an experimental method with a Completely Randomized Design consisting of three treatments and three replications. The feed formulations were P1, consisting of 55% snail meal, 25% Azolla meal, 5% turmeric, 10% corn flour, and 5% tapioca flour; P2, consisting of 39% snail meal, 39% Azolla meal, 7% turmeric, 10% corn flour, and 5% tapioca flour; and P3, consisting of 25% snail meal, 51% Azolla meal, 9% turmeric, 10% corn flour, and 5% tapioca flour. The analyzed parameters included protein, moisture, fat, ash, crude fiber, and carbohydrate contents. Data were analyzed using analysis of variance followed by the Least Significant Difference test. The results showed that feed formulation significantly affected all proximate parameters. P3 produced the highest protein content of 43.87%, fat content of 3.68%, crude fiber of 3.11%, and carbohydrate content of 7.28%, while also producing the lowest ash content of 28.46%. Moisture content ranged from 1.11% to 1.30%, indicating good feed storage stability. These findings demonstrate that the integration of snail meal, Azolla, and turmeric can improve the nutritional quality of alternative Nile tilapia feed and support locally based sustainable aquaculture feed development.

The use of local raw materials in Nile tilapia feed formulation needs to be developed to reduce dependence on increasingly expensive conventional feed ingredients. This study aimed to analyze the effect of different formulations of chicken feather meal and moringa leaf meal with turmeric addition as a phytobiotic on the chemical composition of Nile tilapia (Oreochromis niloticus) feed. The study used a completely randomized design with three treatments and three replications. P1 consisted of 55% chicken feather meal, 25% moringa leaf meal, 5% turmeric, 10% corn flour, and 5% starch; P2 consisted of 40% chicken feather meal, 40% moringa leaf meal, 5% turmeric, 10% corn flour, and 5% starch; and P3 consisted of 25% chicken feather meal, 55% moringa leaf meal, 5% turmeric, 10% corn flour, and 5% starch. The parameters analyzed were crude protein, moisture, ash, crude lipid, crude fiber, and carbohydrate. Data were analyzed using analysis of variance followed by the least significant difference test when significant differences occurred. The results showed that P3 produced the highest protein content (22.60%), ash content (6.65%), crude fiber (6.55%), and carbohydrate (8.45%), whereas P2 produced the highest lipid content (6.54%). Based on chemical analysis, P3 was the most prominent formulation for most proximate parameters. However, this formulation cannot be directly concluded as the best feed for fish growth because digestibility, palatability, feed conversion ratio, growth, survival, and health responses were not evaluated. Further biological testing is therefore required to confirm its feasibility for Nile tilapia culture.

Health issues among the elderly are often related to declining bodily functions, digestive disorders, and specific nutritional needs for easily digestible foods. The 60-and-older age group is at high risk for gastrointestinal disorders due to low fiber intake. Therefore, alternative foods are needed that are soft in texture, neutral in taste, safe, and nutritious. One potential solution is the development of food products based on tempeh gembus with the addition of banana hearts, which are rich in fiber, soft in texture, and readily available. This study employed an experimental method using a Completely Randomized Design (CRD) to test three formulation variations (F1, F2, F3). The nutritional content of formulation F1 includes energy 111.575 kcal, carbohydrates 20.185 g, protein 6.91 g, fat 0.355 g, and fiber 6.67 g. Formula F2 contains 88.225 kcal of energy, 14.095 g of carbohydrates, 7.72 g of protein, 0.205 g of fat, 7.3 g of fiber, and 0.0015% flavonoids. Formula F3 has 107.015 kcal of energy, 7.995 g of protein, 0.295 g of fat, 6.88 g of fiber, and 0.0021% flavonoids. In conclusion, the best tempeh with added banana hearts is Formula F2, with its nutritional content, fiber, flavonoids, and BAL >10⁸ CFU/g, which has the potential to serve as a functional food and probiotic source to help improve digestive health in the elderly. Further testing is recommended directly on elderly groups, along with product shelf-life testing.

The flash floods that struck Aceh Tamiang caused infrastructure damage and contaminated clean water sources, making it difficult for residents to obtain potable water. This situation increases the risk of water-borne diseases and worsens the post-disaster situation. This research aims to develop a large-scale, simple water filtration prototype as an emergency response solution that is effective, economical, and easy to implement by affected communities. The methods used include field observation, water sampling, testing simple physical parameters (turbidity, color, odor, and pH), and designing a gravity-based, multi-stage filtration system without electricity. The prototype uses a combination of filter media such as gravel, silica sand, activated charcoal, and natural fibers in a drum system. Test results show a decrease in turbidity levels from 150–300 NTU to 5–15 NTU after the filtration process, as well as an increase in pH to near neutral. The filtered water is declared suitable for sanitation and consumption after undergoing a further disinfection process. In addition to implementing the technology, this research also includes public education regarding the selection of safe water sources and maintenance of the filtration system. Based on these results, this large-scale simple water filtration prototype is effective as an appropriate technological solution in handling the post-disaster clean water crisis and has the potential to be replicated in other flood-prone areas.

Desa Motu is an area that experiences limited internet access due to the unavailability of conventional ISP services and weak cellular signal coverage. This study aims to develop a community-based RT/RW Net network system to provide internet access by utilizing Starlink as the main ISP and distributing connectivity through networking devices such as MikroTik routers, access points, switches, and fiber optic media. Network testing was conducted by measuring download and upload speeds using network testing ap-plications, evaluating connection stability through latency (ping) measurements, and assessing signal coverage at several user locations. The results show that the implemented RT/RW Net network is able to provide a stable internet connection with consistent speeds at different testing times, as well as optimal signal distribution across multiple measurement points. The authentication system using vouchers, PPPoE, hotspot login, and MAC Binding functions properly, and the free educational access feature also operates effectively. These findings indicate that the RT/RW Net–based community network model can serve as an affordable and sustainable solution for expanding internet access in rural areas.

Pumpkin seeds (Cucurbita spp.) are a byproduct of pumpkin that has great potential to be developed as a functional food ingredient due to their high nutritional content and bioactive compounds. This article aims to examine the valorization (utilization) of pumpkin seeds in various food products and their potential as a functional food. The method used was a narrative literature review through a search of the Google Scholar, ScienceDirect, PubMed, and MDPI databases for the period 2016–2026. The results of the study indicate that pumpkin seeds have been applied in various food products such as cookies, crackers, bread, biscuits, cakes, muffins, and snack bars. The addition of pumpkin seeds generally increases the content of protein, fiber, unsaturated fatty acids, minerals, and bioactive compounds that contribute to antioxidant activity. However, increasing the proportion of pumpkin seeds also affects the physical and sensory characteristics of the product, such as darker color, decreased volume, and changes in texture due to reduced gluten content in the dough. Therefore, formulation optimization is needed to achieve a balance between increasing nutritional value and consumer acceptance. Overall, pumpkin seeds have the potential to be used as an ingredient in the development of functional foods.

This study aims to determine the effect of palm oil fiber (PFFE) (Borassus flabellifer Linn.) levels in egg yolk citrate diluent (C-EY) on the quality of frozen semen from landrace crossbred boar. The material used was fresh semen from 3 landrace crossbred pigs aged 2-3 years. The experimental method was a Completely Randomized Design consisting of five treatments and five replications. T0 = S-KT, T1= C-EY + PFFE 0.75%, T2 = C-EY + PFFE 1.5%, T3 = C-EY + 2.25% PFFE, and T4 = C-EY + PFFE 3%, and the addition of 6% glycerol in each treatment. The parameters observed included motility, viability, abnormalities, and recovery rate of spermatozoa. The data obtained were analyzed using analysis of variance (ANOVA) and analysis using SPSS version 27. The results revealed that the addition of PFFE had a significant effect (P <0.05) on post-thawing semen motility. With a value of T2: 24.00±2.23%, followed by T3: 15.00±5.00%, T1: 14.00±6.51%, T4: 13.00±4.47% and T0: 12.00±7.58%. Post-thawing viability also revealed that the addition of palmyra fruit fiber extract had a significant effect (P<0.05) with a T2 value of 46.65±3.65% followed by treatment T3: 25.70±6.75, T1: 24.69±8.70, T4:24.24±7.81 and T0: 22.36±8.67. While semen abnormalities did not have a significant difference between treatments. It can be concluded that the use of 1.5% SSBL and S-KT resulted in the highest post-thaw semen motility in treatment P2, with a value of 24.00 ± 2.23% in crossbred Landrace boar semen.

This study aims to evaluate the growth performance of KUB chickens fed with a combination of fermented agricultural waste, specifically Maggot BSF (Hermetia illucens) and Azolla microphylla. A total of 96 KUB chickens aged 30 days were used in a Completely Randomized Design (CRD) with four treatments and four replications. The treatments consisted of a basal diet substituted with the fermented waste combination at levels of 0% (P0), 5% (P1), 10% (P2), and 15% (P3). Parameters observed included feed consumption, body weight gain (BWG), and Feed Conversion Ratio (FCR). The results showed that increasing the level of waste substitution significantly affected feed consumption due to the bulky nature of the fiber, yet body weight gain remained stable across all treatments. The FCR values ranging from 3.21 to 3.25 indicated that the high-quality protein from Maggot BSF effectively compensated for the reduced feed intake. It is concluded that the substitution of fermented agricultural waste up to 15% (P3) is an optimal and efficient formulation to maintain the growth performance of KUB chickens.

Coal mining activities in East Kalimantan have significantly contributed to regional economic development, but they have also resulted in extensive land degradation that requires effective reclamation strategies. The integration of forage crops in reclaimed mine lands offers an opportunity to simultaneously support ecological restoration and livestock production. However, the performance of forage grasses under shaded conditions created by revegetation trees remains insufficiently understood. This study aimed to evaluate the physiological responses, morphological characteristics, and nutritional quality of two forage grass species, Brachiaria humidicola and Stenotaphrum secundatum, grown under shaded conditions on reclaimed coal mine land. The experiment was conducted at the PT Kitadin Embalut reclamation site, East Kalimantan, using a split-plot design with two shading levels (0% and 50%) as the main plots and two grass species as subplots. Each treatment was replicated six times. Variables measured included dry matter yield, leaf-to-stem ratio, chlorophyll content (a, b, and total), crude protein, and crude fiber content. The results showed that a 50% shading level significantly influenced physiological and morphological responses of the grasses. Stenotaphrum secundatum exhibited a marked increase in chlorophyll content under shaded conditions, indicating a stronger acclimation to low light environments compared with Brachiaria humidicola. Shading also reduced the leaf-to-stem ratio in both species. However, dry matter production was not significantly affected by shading, suggesting that both grasses were able to maintain biomass accumulation under moderate shade conditions. Shading slightly reduced crude protein and crude fiber contents.

This study evaluated the feeding behavior and palatability of Etawa Crossbred (PE) dairy goats fed diets with partial substitution of Cnidoscolus aconitifolius forage. An in vivo field experiment was conducted using a Completely Randomized Design with four dietary treatments and three replications. The treatments consisted of: (T0) Leucaena leucocephala (lamtoro) as the basal forage; (T1) lamtoro supplemented with concentrate; (T2) lamtoro plus concentrate with 10% substitution of lamtoro dry matter by C. aconitifolius; and (T3) lamtoro plus concentrate with 20% substitution of lamtoro dry matter by C. aconitifolius. Parameters observed included feed intake (dry matter, organic matter, crude protein, and crude fiber), body weight change, and feeding behavior related to forage preference. The goats consistently consumed forage prior to concentrate and exhibited a higher preference for diets containing C. aconitifolius. Inclusion of C. aconitifolius reduced lamtoro intake; however, no significant differences were observed among treatments for dry matter, organic matter, crude protein, or crude fiber intake (P>0.05). Body weight change showed a positive tendency in goats receiving 10% and 20% C. aconitifolius substitution, while goats fed the control diet experienced slight weight loss, although these differences were not statistically significant (P>0.05). In conclusion, C. aconitifolius demonstrated good palatability and potential as an alternative forage for PE goats when used as a partial substitute for lamtoro. Nevertheless, its inclusion at the tested levels did not significantly affect nutrient intake or body weight change. Further studies are recommended to optimize inclusion levels and feeding strategies to enhance its practical application in small ruminant production systems.

Natural fiber based composite materials are increasingly being developed as an environmentally friendly alternative to synthetic fiber-based composites. This study aims to characterize the thermal and mechanical properties of natural fiber composite materials and evaluate their potential use as sustainable materials. Composites are made using natural fibers as reinforcement and a polymer matrix through a specific molding method. Mechanical property characterization includes tensile tests, flexural tests, and impact tests, while thermal property characterization is carried out using thermal analysis to determine the thermal stability of the material. The test results show that the addition of natural fibers has a significant effect on improving the mechanical properties of the composite, especially tensile strength and elastic modulus, compared to the unreinforced matrix. In addition, natural fiber composites show quite good thermal stability over a certain temperature range, making them suitable for non-structural applications. Based on these results, natural fiber composite materials have the potential to be developed as environmentally friendly materials that have competitive mechanical and thermal performance.

Hypertension is a significant global health problem, especially in specific groups such as pregnant women. The high incidence and potential for serious complications demand non pharmacological management efforts and innovative use of local foods. This study examines the potential of local functional foods such as Ambon bananas, banana blossoms, and bamboo shoots as alternatives for health management and product development, particularly those related to hypertension in pregnant women. The method used was a systematic literature review using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) approach, which encompasses four main stages: identification, screening, feasibility assessment, and analysis of results.The study results showed that the Ambon banana diet significantly reduced systolic and diastolic blood pressure. Factors such as age, family support, stress levels, and fast food consumption were shown to be significantly associated with the incidence of hypertension in pregnant women. Furthermore, bamboo shoot consumption significantly reduced blood cholesterol levels and blood pressure. In terms of product innovation, the fish floss formulation combined with banana blossoms or bamboo shoots received positive feedback from the panelists. The fermentation process of bamboo shoots is known to produce flour with a very high crude fiber content. Therefore, this local food has significant potential as a source of additional fiber and a raw material for value-added processed products to support food security and improve public health.
