Abstract

Palm oil emulsion drink is one of the food diversification product, containing high provitamin-A. The dispersed phase of the emulsion is palm olein, while the rest was water as the dispersion medium (ratio 7:3). The low content of dispersion medium in the emulsion caused the rheological properties, droplet size and distribution, as well as its level of stability to be different from other commercial product of beverage emulsion. This research investigated the effect of storage time on the rheological properties, droplet size distributions and stability of the emulsion. The emulsion morphology was observed by polarized light microscopy, while its size and distribution were analyzed by dynamic light scattering technique using Zetasizer. The rheological analysis, including the determination of the flow behavior and consistency index, were measured using a rotational dial reading viscometer. The results showed that increasing of storage time led to increased droplet size and distribution (d4.3 value from 4.83 to 6.12 µm, value of flow behavior index from 0.9782 to 0.9873, and consistency index from 3.473 to5.047 Pa.sn). However, this condition also caused a decrease in emulsion stability (from 0.880 to 0.823). According to Pearson’s correlation coefficients, the droplet size was negatively correlated with emulsion stability (R = -0.907; α = 0.01). However, the droplet size were positively correlated with the flow behavior index (R = 0.778; α = 0.01) and consistency index (R = 0.939; α = 0.01). These results may help formulate palm oil emulsion drink with improved stability and shelf-life.

Abstract

Fish is highly susceptible to deterioration without any preservative or processing measures and requires proper handling and preservation to increase its shelf life. Smoked fish is traditionally processed by fish through an open process of hot smoked. Smoked fish process in Indonesia, especially in Papua, is still carried out traditionally with capital and small business scale so that the use of tools is still simple. The aim of this research was to study the proximate composition of smoked yellowfin fish, which were taken from different producers in Youtefa Market, Jayapura City, Papua. The analysis on smoked yellowfin fish applied of proximate analysis (moisture level, ash level, fat level, and protein level). The result of this research showed that the highest moisture level was EK.K sample with 67.17%.  The highest value of ash level was EK.T­1 sample with 8.15%. The highest of fat and protein level were EK.K sample, with 18.63% and 6.42%, respectively.  Key words: Smoked yellowfin, proximate analysis.

Abstract

The research was conducted in June to August 2022 in Ubiyau Village, Yanamaa Village and Yuwanain Village, Arso District, Keerom, Papua. The aim of the study was to determine the impact of forest conversion to oil palm plantations on the diversity and abundance of the Superfamily Papilionoidea butterfly. The line transect count method was used for sampling butterflies with a transect length of 1500 m at each study area. Sampling was carried out along a line transect in an imaginary box measuring 10 x 10 x 10 m which was carried out on sunny days from 09.00 am to 14.00 pm. The highest species diversity of the Superfamily Papilionoidea was found in Secondary Forest (HS), namely 70 species consisting of Papilionidae (8 species), Pieridae (5 species), Lycaenidae (21 species) and Nymphalidae (36 species). There were 42 species of butterflies recorded from Non-Productive Oil palm Plantations consisting of Papilionidae (5 species), Pieridae (4 species), Lycaenidae (11 species) and Nymphalidae (22 species). While the lowest number of butterfly species was encountered in Productive Oil Palm Plantations namely 32 species consisting of Papilionidae (5 species), Pieridae (3 species), Lycaenidae (8 species) and Nymphalidae (16 species). These data indicated that conversion of secondary forest to oil palm plantations reduced butterfly species by around 40-53%. The highest Shannon-Wiener Diversity Index (H') and Margalef Diversity Index (Dmg) values were found in secondary forest (H'=3.4; Dmg =13.7) followed by Non-Productive Oil Palm Plantations (H'=2.5; Dmg=7.2) and Productive Oil Palm Plantations (H=2.0; Dmg=6.1). The highest species similarity was between Secondary Forest and Productive Oil Palm Plantations with Sorensen Index value IS=60%, followed by Non-Productive Oil Palm Plantations and Productive Oil Palm Plantations (IS=51%) and the lowest species similarity index was between Secondary Forests and Non-Productive Oil Palm Plantations (IS = 46%). In Secondary Forest the composition of the number of individuals per species tends to be more evenly distributed compared to oil palm plantations. Forest conversion to Oil Palm Plantations has a negative impact on butterfly species diversity of the Superfamily Papilionoidea. The lost species that were not found in oil palm plantations were forest specialist species with small range sizes and niches as well as specific diets that were only found in forest. Key words: Papilionidae; primary forest; Pieridae; Nymphalidae; Lycaenidae; Keerom.

Abstract

This research aimed to determine the role of butterflies as pollinators of various horticultural plants and wild flowering plants at the agro-ecosystem in Arso District, Keerom Regency. Data collection on butterfly nectar sources used the Visual Count Method and All Out Search Method (AOSM) at Arso District every week for 4 months (May-August 2023). From the survey results, it was discovered 32 species of butterflies of Superfamily Papilionoidea that consisted of Paplionidae (9 species), Pieridae (6 species), Nymphalidae (12 species) and Lycaenidae (5 species). These butterflies visited flowering plants as a source of nectar. It was found 25 species of flowering plants consisting of 10 families which were sources of nectar for butterflies, namely Asteraceae, Rubiaceae, Malvaceae, Lamiaceae, Orchidaceae, Verbenaceae, Fabaceae, Amaranthaceae, Cucurbitaceae, and Rutaceae. The flowering plants most visited by butterflies were Bidens pilosa (15 species), Stachytarpheta urticaefolia (14 species), and Lantana camara (10 species). Asteraceae is the family of flowering plants most visited by butterflies, recorded 19 species. Butterflies have an important role in helping to pollinate wild flowering plants and horticultural plants in the agroecosystem in Arso District. The Papilionidae and Nymphalidae families were efficient pollinators because of their high mobility and large body size which could transfer more pollen from one flower to another. Pieridae visit more flowering plants than any other butterfly family, of the 25 species of flowering plants, 23 of them are visited by Pieridae. Even though the Lycaenidae are less efficient in helping pollination because they visit more limited flowers as a result of their limited body size and flight power, especially plants that had small flowers such as bitter melon, long beans and cucumbers.  Key words: Lycaenidae; Nymphalidae; pollinator;  Papilionidae;  Pieridae.

Abstract

Poor food safety in school children’s snacks (SCSS), characterized by the presence of hazardous additives like borax, formalin, and rhodamine B, poses significant risks to children's health, potentially leading to long-term health issues and developmental problems. This research aims to identify the presence of these dangerous substances in SCSS and determine which types of snacks pose the highest food safety risks. The study employed a simple random sampling method to collect popular snack samples frequently consumed by students in various areas of Jayapura. Qualitative testing for borax, formalin, and rhodamine B was carried out using test kits. The results revealed that several SCSS samples contained these harmful substances, with notable variability across different regions. The analysis identified specific types of snacks—such as meatballs, noodles, colorful beverages, and snacks—that failed to meet the expected food safety standards. The study concludes that hazardous food additives are still being used in the production and sale of SCSS in Jayapura City, posing significant health risks to children. Enhanced regulation and awareness initiatives are necessary to improve food safety in the region. Public health authorities are encouraged to implement stricter monitoring and provide targeted education to both vendors and consumers to reduce the prevalence of these unsafe practices. Key words: food safety; hazardous additives; Jayapura City; public health; school snacks.

Abstract

Local cocoa offers substantial value-addition opportunities for women-led microenterprises, yet gaps in processing skills, basic business practices, and market access constrain outcomes. This community service program empowered a women’s fellowship through structured, participatory training on cocoa-based product development. Objectives were to strengthen technical competencies for two ready-to-consume products (chocolate drink and chocolate jam), introduce basic business management (cash records, cost of goods sold/COGS, pricing), and build entry-level digital marketing and branding skills. Methods combined a community-based participatory approach (coordination, needs assessment, material preparation) with sequential sessions orientation, lecture discussion, hands-on practice, reflection and mixed-method evaluation (pre/post Likert survey and rubric-based observation). Ten participants completed the training. Results show participants replicated both products with more consistent quality, applied hygienic handling (heating/sterilization), and prepared simple business documents (cash ledger, COGS). Foundational brand assets (product name, basic label, initial promotional content) supported early commercialization, while collaborative work routines and peer champions emerged to sustain production. In conclusion, the intervention effectively enhanced technical, managerial, and promotional readiness and offers a practical model for community-based microenterprises that add value to local cocoa resources.
