The purpose of this research was to observe the student’s collaboration of food technology department in 2019 through basic physics practicum. The research method used classroom action research which was divided into four parts, that is planning, action, observation, and reflection. This research was done into four groups and accompanied by each observer. They had to take responsibility to observe the collaboration skill of each student in the group. The results of this research showed that the collaboration skill increased in every part. Group one of the first part showed a result of 45% with moderate success criteria, it increased in the second part to 51.11% (moderate), it increased in the third part to 76.67% (high), and it increased in the fourth part to 92.78% with very high success criteria.

After harvesting, fruits will change due to physiological, physical, chemical, and microbiological influences, and they are living materials. Therefore, it is necessary to know how to harvest and handle fresh fruits and their storage conditions to handle the fruits after harvesting so that the quality of the products can be maintained. One of the first treatments in the fruit cold chain is evaporative cooling. In order to get an evaporative cooling system that has an even temperature distribution, it is necessary to make a spatial model when designing an evaporative cooling system using CFD (Computational Fluid Dynamics). The objectives of this research are: (1) design of direct flow type evaporative cooling systems and (2) test the performance of direct flow type evaporative coolers. This research method uses design methods, experiments, and computer simulations. The results showed the performance of the evaporative cooler system in the scenario with the roof on, the highest effectiveness value was 1.198, the highest approximation value was 2.832, and the highest range value was 4.589. In the scenario without a roof on the evaporative cooler system, the highest effectiveness value was 1.767, the highest approach value was 2.139, and the highest range value was 4.835. The CFD analysis in the scenario with a roof had the highest temperature value of 25.9 ° C and the lowest temperature of 21.9 ° C, while the CFD analysis in the scenario without roof had the highest temperature of 23.7 ° C and the lowest temperature of 20.4 ° C.

Heat moisture treatment (HMT) refers to a physical method for altering physicochemical and molecular properties of root and tuber starches. Principally, the starch's moisture content is adjusted to 10-35% and then exposed to heat (90-120°C) above the glass transition and gelatinization temperature for 15 minutes until 16 hours. Low moisture content did not allow starch gelatinization. In this work, cocoyam starch was modified using HM, with the moisture content of 25% and heating temperature of 105°C for 4 hours. Results show that HMT did not disrupt the cocoyam starch granule structure, while it increased swelling power and water binding capacity and decreased oil binding capacity compared to native starch.

This work aimed to evaluate the effect of taro (Xanthosoma sagittifolium) starch addition as filler on the physical and sensory properties of oyster mushroom substituted chicken nugget. This research used a complete randomized design with two factors: 1) chicken and oyster mushroom proportion and 2) taro starch percentage. Additional taro starch percentages of 10% (K1), 20% (K2), and 30% (K3) significantly affect the hardness of chicken nuggets. On the other hand, the increasing proportion of oyster mushroom to chicken affect vice versa. The chicken and oyster mushroom proportion of 25:75 (F4) on the additional percentage of 20% (K2) and 30% (K3) showed a higher mean value than 10%taro starch addition (K1). The highest hedonic score was chicken nugget with 75% (F4) and 100% (F5) oyster mushroom addition, ranged from 3.80 (quite like) and 4.20 (like). In contrast, taro starch addition as filler had no significant effect on the nugget's hedonic score.

Noodles are typically made from wheat flour, which contains gluten, making them less suitable for individuals with gluten intolerance. This study aims to investigate the effect of the proportion of yam flour and mocaf on the quality of noodles and optimize the formula to achieve the best quality response from gluten-free dry noodles using a D-optimal design. The responses analyzed included cooking quality (cooking time and cooking loss) and texture profile (hardness, cohesiveness, springiness, and chewiness). The results showed that increasing the yam flour proportion (24,58-34,4%), combined with reducing mocaf proportion (24,57-14,75%), could decrease cooking time (7.3–6.3 minutes), cooking loss (14.51–10.17%) and increased hardness (248.12–857.48 gf), cohesiveness (0.45–0.75), springiness (0.46–0.78), and chewiness (97,60–330,35). The optimal formula was obtained in a composition of 34.39% gembili flour and 14.76% mocaf flour with a desirability value of 0.710. The characteristics of the best formulation results include a cooking time of 6.3 minutes, a cooking loss of 10.69%, a hardness of 662.42 gf, a cohesiveness of 0.70, a springiness of 0.78, and a chewiness of 249.91. Verification shows that the actual response value is within the predicted range, indicating that the model is valid for application in the development of gluten-free noodles from local ingredients.

Program pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kualitas, keamanan, dan daya saing produk olahan ikan di desa-desa pesisir melalui penerapan Good Manufacturing Practices (GMP) dan Sanitation Standard Operating Procedures (SSOP). Kegiatan dilaksanakan dengan metode partisipatif yang melibatkan pelaku usaha, kelompok nelayan, pemerintah desa, dan pendamping teknis, melalui tahapan identifikasi permasalahan, sosialisasi, pelatihan, pendampingan lapangan, serta monitoring dan evaluasi. Hasil kegiatan menunjukkan adanya peningkatan signifikan pada kapasitas teknis dan kesadaran masyarakat terhadap pentingnya sanitasi dan higiene pangan, efisiensi proses produksi, penurunan risiko kontaminasi mikrobiologis lebih dari 50%, serta perbaikan mutu sensoris produk, termasuk warna, tekstur, dan aroma yang lebih segar. Keberhasilan program ini memperkuat posisi produk olahan ikan di pasar lokal dan membuka peluang penetrasi pasar luar daerah. Model penerapan GMP dan SSOP yang terdokumentasi berpotensi direplikasi di desa pesisir lain sebagai strategi membangun industri perikanan lokal yang higienis, ramah lingkungan, dan berdaya saing tinggi.

Butterfly pea (Clitoria ternatea L.) is an indigenous Indonesian flower that is usually consumed as a natural ingredient in herbal drinks and nutraceutical products. It contains several bioactive compounds that showed strong antioxidant activity to neutralize free radical compounds from foods. The aim of this study was to identify the bioactive compounds, antioxidant capacity and the organoleptic characteristics in the brewed of dried butterfly pea. The experimental design of this study used a completely randomized design with two factors: 1) dried butterfly pea content in water : 0,5; 1,0; dan 1,5 (g/200 ml) and 2) brewing levels (1, 2, and 3 times). The phytochemical screening analysis revealed that the brewed butterfly pea contained bioactive compounds such as flavonoids, tannins, saponins, steroids, and triterpenoids. The longer dried butterfly peas soak in water showed the higher level of total anthocyanin content, total phenolic compounds, and antioxidant activity. Organoleptic analysis showed significantly effect of the colour but not the odour or flavour of the brewed dry butterfly pea.

Pengabdian kepada masyarakat ini dilaksanakan pada forum UMKM Ngombol Jempol, di Kecamatan Ngombol Kabupaten Purworejo Jawa Tengah yang merupakan daerah pesisir. Tujuan dari kegiatan ini yaitu meningkatkan pemahaman pelaku UMKM mengenai produk ikani yang dengan mudah dapat diproduksi seperti sosis udang. Tahapan yang dilakukan diawali dengan penyampaian materi terkait alat dan bahan yang digunakan untuk membuat sosis udang dan tahapan proses pembuatannya hingga teknik pengemasan yang baik yang dilanjutkan dengan demonstrasi 2 kelompok. Hasil percobaan selanjutnya dilakukan uji proksimat dan uji organoleptik untuk mengetahui tingkat kesukaan konsumen terhadap sosis udang yang dihasilkan. Berdasarkan hasil uji proksimat, kandungan rata-rata protein sebesar 16,12 %, hal ini telah melampaui batas minimum kandungan protein sosis dalam Standar Nasional Indonesia (SNI). Sedangkan apabila dilihat dari uji organoleptik, flavor menurut panelis agak enak dengan tekstur agak kenyal. Panelis menyukai kedua jenis sosis yang secara umum bersisar antara 2,96-3,16 (agak suka).
