Abstract

Alginate extracted from brown seaweed has gelling properties that make it useful as a wall material in encapsulation systems. Liquid smoke contains the active substances, such as phenols, which can preserve food. In order to protect the active substances, liquid smoke is encapsulated by using alginate and maltodextrin. The purpose of this study was to investigate liquid smoke encapsulation technology with maltodextrin and alginate using a spray dryer, to improve the physical and chemical characteristics of the liquid smoke. The microcapsules of liquid smoke were made, using a spray dryer SD 04, by encapsulating liquid smoke with two types of wall materials, maltodextrin and the combination of alginate- maltodextrin. The ratio of liquid smoke to total solids (wall materials) was 9:1 (v/w). The alginate concentration used was 0.5 to 2% (w/v). Parameters observed in this study were phenol release, shape and morphology, encapsulant efficiency, drying yield, phenol marker and, particle size. This study used a completely randomized design with three replications. The best treatment was obtained by using the alginate with a concentration of 1% (w/v) and maltodextrin of 9% (w/v) with phenol release of 2.52% (w/w) in the 20 minute of release, encapsulant efficiency of 45.13% and drying yield of 28.74%. The particle size analyzer results showed that the particles were agglomerating. Scanning electronic microscope (SEM) observation illustrated that all treatments have a better capsule morphology than the controls, whereas Optilab image processing and analysis software results showed that phenolic compounds are encapsulated by wall materials used.

Abstract

Penggunaan kunci manual sebagai pembuka dan pengunci pintu masih belum optimal. Masalah yang sering terjadi adalah pemilik kunci sering kali lupa dimana menyimpan kunci bahkan hingga terjadi kehilangan kunci. Sistem biometrik pola suara memiliki ciri khas dan karakteristik yang berbeda pada setiap manusia, maka suara dapat dijadikan salah satu alternatif solusi, yaitu suara sebagai kunci untuk membuka pintu secara otomatis sehingga lebih efisien. Otomatisasi sistem pengunci pintu dibuat menggunakan Elechouse v3 yang berfungsi sebagai voice recognition serta Solenoid lock door sebagai pengunci otomatis pada pintu. Hasil pengujian fungsional menggunakan black box menunjukkan bahwa seluruh alat yang dirangkai berfungsi sesuai fungsinya. Pengujian tingkat keberhasilan sistem dilakukan menggunakan variable derau, non derau dan jarak. Pada data training tingkat keberhasilan sistem ini jika tanpa derau adalah 100%, sedangkan dengan derau 50.0 dB hingga 70 dB rata-rata tingkat keberhasilannya adalah 56,2%. Untuk jarak 30 cm sampai 180 cm rata-rata keberhasilannya sebesar 40,51%. Jarak terjauh adalah pada jarak 150 cm dengan presentase keberhasilan 5%. Pada data testing tingkat keberhasilannya jika tanpa derau adalah 0%, sedangkan dengan derau 50.0 dB hingga 70 dB rata-rata tingkat keberhasilannya adalah 1,9%. Untuk jarak 30 cm sampai 180 cm rata-rata keberhasilannya sebesar 0%.The use of manual locks as door openers and locks is still not optimal. The problem that often occurs is that the key owner often forgets where to store the key and even loses the key. The voice pattern biometric system has different characteristics for each human, so sound can be an alternative solution, namely voice as a key to open doors automatically so that it is more efficient. Door lock system automation is made using Elechouse v3 which functions as voice recognition and Solenoid door lock as automatic locking of doors. The results of functional testing using a black box show that all the tools assembled function according to their function. Testing the success rate of the system is carried out using noise, non-noise and distance variables. In the training data, the success rate of this system without noise is 100%, while with a noise of 50.0 dB to 70 dB the average success rate is 56.2%. For a distance of 30 cm to 180 cm the success rate is 40.51%. The farthest distance is at a distance of 150 cm with a success percentage of 5%. In the testing data, the success rate without noise is 0%, while with a noise of 50.0 dB to 70 dB the average success rate is 1.9%. For a distance of 30 cm to 180 cm the success rate is 0%.

Abstract

Sipunculans, or peanut worms, are unsegmented worm-like marine organisms with distinctive trunk-like bodies. They play important roles in marine ecosystems, such as bioerosion, bioturbation, and food sources. Sipunculans are also harvested as human food in some regions worldwide. Despite their importance, a comprehensive understanding of the Sipuncula in Indonesia is still limited. This work aimed to compile a study of the distribution, ecology, and potency of Sipuncula species in Indonesian waters. The distribution of Sipuncula species in Indonesian waters was recorded from the northernmost to the easternmost part of Indonesia. So far, nineteen species have been found in Indonesian waters and are dominated by Sipunculus nudus. In Indonesia, Sipuncula exhibits a diverse range of habitats, they can be found in seagrass, mangrove and coral reef ecosystems, in both sandy and muddy sediments. Sipunculans found in Indonesia have ecosystem function as bioturbator, shell-utilizer, and coral-symbiotic species. Sipuncula also has potency as a food and nutraceutical for human health maintenance because it contains highly nutritious such as protein, carbohydrates, ash, lipids, moisture, minerals, amino acids, and fatty acids. In some areas in Indonesia, local communities use Sipuncula as a traditional food source and fishing bait. Given its significance for marine ecosystems and human livelihoods in Indonesia, future management strategies should include regulations on catch size and management practices, data collection, promotion of sustainable fishing practices, and research on Sipuncula biology and ecology. Addressing these knowledge gaps will help to ensure the sustainable use and conservation of Sipuncula in Indonesia.

Abstract

Pangasius sp., Thunnus tonggol (T. tonggol), and Thunnus albacares (T. albacares) are high-value commercial species widely used in fillet production, generating by-products, such as fishbone. The fishbone, rich in calcium (CA) and phosphorus (P), offers a valuable alternative for daily Ca intake. Using such by-products as a potential source of Ca presents a viable solution, offering food-fortificant ingredients applicable in various food products. Therefore, this study examined the physical and chemical properties of fishbone powder derived from Pangasius sp., T. tonggol, and T. albacares. The products preparations were subjected to cooking, autoclaving, pulverization, homogenization, drying, and grinding. The physical and chemical analysis of fishbone powder showed that T. tonggol and T. albacares had a darker color compared to Pangasius sp., with higher protein content and likely stimulation of a Maillard reaction during the drying process. All species maintained a neutral pH range, and their particle sizes significantly differed (p< 0.05), ranging from nm to µm. SEM images showed irregularly shaped and agglomerated particles in all fish species. The ash content was 54.35 g/100 g (Pangasius sp.), 53.62 g/100 g (T. tonggol), and 52.28 g/100 g (T. albacares), showing high mineral content, particularly in Ca exceeding 40%. The analysis of a Fourier transform infrared spectroscopy (FT-IR) showed carbonate and phosphate peaks, representing the presence of calcium salts. Based on the evaluation, fishbone powder for each species had the potential to serve as food fortificant.
