Abstract

ARTICLE HIGHLIGHTS Indigenous communities read animal signs as early warnings for nature events Shared experiences shape how different animal behaviours gain meaning Local wisdom shows animals as sensitive partners in human survival   ABSTRACTObserving animal behavior and daily activities can help humans gain knowledge and derive practical benefits. A mixed-method approach, combining desk-based study and telephone interviews, was employed to collect data from seven major Papuan tribal groups. The desk study involved the collection of approximately 2,000 references published between 1980 and 2020 using keyword-based searches conducted with specialized software. Data were also provided by leaders from the seven major communities. The collected data were analyzed using Rayyan, VoS Viewer, Crammer’s Phi, and Microsoft Excel. The principal findings indicate that 14 publications addressed topics related to animal signaling and community beliefs. The animals recognized by the seven major tribal group as exhibiting signals included mammals (52%), fish (8%), reptiles (12%), amphibians (8%), birds (4%), and insects (16%). Animals were reported to convey signals through vocalizations (sounds), appearance, body parts, wastes, tracks, constructed objects, and odors. The result of Crammer’s Phi analysis showed (168) = 219.48, P = 0.0046, df = 168,  = 0.05 and 0.01, and φc = 0.0105 (1%). This results indicate a significant association between perceived values in interpreting animal signals and tribal community groups in West Papua. A Cartesian graph demonstrated low-to-high levels of both animal signaling and beliefs. Beliefs and practices related to animal sensitivity and communication vary across cultures and communities worldwide. Many indigenous communities maintain a deep spiritual connection with nature and animals, viewing them as sentient beings with their own forms of communication and sensitivity.

Abstract

This study evaluated the effect of different dehydration methods, specifically oven drying (60°C) and freeze-drying (-20°C to 65°C), on the antioxidant activity of Cilembu sweet potato (Ipomoea batatas L. Lam) flour and its functional application in chicken meatballs. The antioxidant capacity was measured using the DPPH radical scavenging assay, with results showing that freeze-drying significantly preserved higher levels of bioactive compounds compared to thermal evaporation. Freeze-dried tuber flour reached a radical scavenging activity of 55.74 mg/ml, and when applied to meatballs as a 15% substitute for tapioca flour, it exhibited a superior antioxidant activity of 41.7%. This value was significantly higher (P<0.01) than the oven-dried treatment (28.85%) and the control group (13.22%). The enhanced retention of antioxidants in freeze-drying is attributed to the sublimation process, which minimizes the oxidation and thermal degradation of heat-sensitive molecules such as beta-carotene and phenolic compounds inherently found in Cilembu sweet potatoes. In conclusion, freeze-drying is the more effective processing method for maintaining the functional integrity of local Indonesian tubers, providing a high-quality ingredient for the development of standardized functional foods.

Abstract

Phenotypic evaluation of contest cattle provides useful information for understanding body conformation and physical condition under field conditions, yet objective studies on contest-based cattle populations remain limited. This study aimed to evaluate morphometric traits and body condition score (BCS) of contest cattle from Sorong Regency, Southwest Papua, and to assess their variation according to district and sex, as well as the relationships among measured traits. Data were collected from 31 contest cattle originating from seven districts, consisting of 8 males and 23 females. The evaluated variables included chest girth (CG), body length (BL), withers height (WH), and BCS. Descriptive statistics were used to summarize the data, while sex and district effects were analyzed using the Mann–Whitney U test and Kruskal–Wallis test, respectively. Relationships among variables were examined using Spearman’s rank correlation, and principal component analysis (PCA) was applied to describe the multivariate structure of morphometric variation. The overall mean values were 152.60 ± 25.99 cm for CG, 108.26 ± 10.83 cm for BL, 116.58 ± 12.66 cm for WH, and 3.19 ± 0.54 for BCS. No significant differences were found between males and females for any variable. In contrast, district had a significant effect on WH and BCS, with the main difference occurring between Aimas and Mariat. Chest girth was positively correlated with BL (rho = 0.66, p < 0.001) and BCS (rho = 0.54, p < 0.01), indicating that this trait was the most informative single morphometric variable in the dataset. PCA showed that the first two principal components explained 87.55% of the total variation, representing general body size and vertical body structure. In conclusion, contest cattle in Sorong Regency exhibited greater phenotypic variation across districts than between sexes, and chest girth may serve as a practical indicator for field-based phenotypic evaluation of contest cattle.

Abstract

Telur ayam merupakan produk peternakan yang mudah rusak sehingga memerlukan metode pengawetan, salah satunya melalui perendaman dengan ekstrak bawang dayak (Eleutherine palmifolia (L.) Merr) yang mengandung tanin. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) faktorial dengan dua faktor, yaitu konsentrasi ekstrak (30, 40, 50%) dan lama perendaman (12, 24, 36 jam) dengan dua ulangan. Analisis data dilakukan menggunakan ANOVA dan uji lanjut DMRT. Hasil penelitian menunjukkan bahwa tidak terdapat interaksi signifikan (P>0,05) antara konsentrasi dan lama perendaman terhadap sebagian besar parameter kualitas telur. Namun, secara deskriptif ekstrak bawang dayak mampu menekan peningkatan pH albumin dan yolk melalui peran tanin dan fenolik dalam menghambat penguapan CO₂ serta mencegah kontaminasi mikroba. Rataan pH albumin berkisar 7,16–7,42, sedangkan pH yolk menurun pada konsentrasi 30–40% dan relatif stabil selama perendaman. Yolk score meningkat pada konsentrasi 30% dengan nilai 8,56 dibanding kontrol 7,72, menunjukkan perbaikan intensitas warna kuning telur. Secara umum, perendaman dalam ekstrak bawang dayak mampu memperlambat penurunan kualitas eksterior dan interior telur serta berpotensi memperpanjang masa simpan telur konsumsi

Abstract

Product development in the food industry now focuses not only on taste and texture but also on improving nutritional value, including increasing dietary fiber content. This study examined the effect of adding vegetables at levels of 0%, 5%, 10%, and 15% on the dietary fiber content and consumer acceptance of chicken nuggets. The findings indicate that increasing the percentage of added vegetables has a significant effect (P<0.05) on enhancing dietary fiber content, but it also leads to a decrease in panelists’ acceptability scores. At the 15% level, dietary fiber reached 7.73%, although consumer acceptance fell into the “slightly like” category. Overall, a 10% addition is considered the optimal level, as it increases dietary fiber while maintaining relatively good consumer acceptance.
