Bulay Village has an entrepreneurial spirit, with the idea of creating, developing, and managing new businesses and exploiting its papaya production potential. This innovation involves processing papaya chips (kreeyaa), which is expected to increase income. The goal of the PKM is to improve the community's economy by providing training and guidance on processing papaya into marketable products, motivating the community to generate creative ideas using existing resources, and establishing papaya chips businesses. The method used is partisipatory Action Research, an approach based on the assets, strengths, and potential of the community. Entrepreneurship mentoring seminars and training on making papaya chips (kreeyaa) in Bulay Village are expected to create jobs, develop community skills, and increase income by leveraging potential assets.

Local food innovation is not only focused on product development but also requires effective communication strategies to build positive perceptions and enhance market competitiveness. This study aims to analyze the implementation of innovation communication strategies by micro, small, and medium enterprises (MSMEs) in developing papaya-based chili chips as a flagship product in Nagori Karang Anyar, Gunung Maligas District, Simalungun Regency. The research employs a descriptive qualitative approach, focusing on the product innovation process, marketing communication patterns, and efforts to build product image amid competition in the local food industry. The findings indicate that innovation communication strategies play a crucial role in creating product differentiation through narratives of unique taste, utilization of local raw materials, and promotional strategies combining traditional methods and digital media. Papaya chili chips are positioned as a product that blends distinctive local flavors with a modern touch, attracting consumer interest and increasing the added value of papaya as a local commodity. This study emphasizes that the success of local food innovation depends not only on product quality but also on the ability of MSMEs to manage adaptive and persuasive communication strategies.

Papaya fruit (Carica papaya L.) is a tropical plant widely consumed as food and known to contain various bioactive metabolites with potential health benefits. The increasing interest in natural products as functional resources highlights the importance of reviewing the chemical characterization and health applications of papaya bioactive compounds. This article aims to systematically review the types of bioactive metabolites found in papaya fruit, the chemical characterization methods applied, and their potential applications in the health sector. This review was conducted through a literature study of relevant scientific articles, focusing on metabolite identification and biological activity evaluation. The results indicate that papaya fruit contains diverse bioactive metabolites, including flavonoids, phenolic compounds, alkaloids, saponins, terpenoids, and proteolytic enzymes. These compounds are commonly characterized using chromatographic and spectroscopic techniques. Several studies have reported that papaya bioactive metabolites exhibit biological activities such as antioxidant, antimicrobial, anti-inflammatory, and antidiabetic effects. This review suggests that papaya fruit has promising potential as a functional natural resource for health and pharmaceutical applications.

A high-fat diet can cause hyperlipidemia, which is one of the main risk factors for atherosclerosis. Papaya flowers (Carica papaya L.) contain antioxidants that have the potential to inhibit the development of atherosclerotic lesions. This study aims to determine the effect of papaya flower extract on the histopathological features of the aorta of Wistar rats induced by a high-fat diet. The study design is a posttest only-trial group design. The study sample consisted of 25 male Wistar rats divided into 5 groups with treatment for 21 days. Group A received no treatment. Group B was given high-fat diet consisting of 3 mL of pork fat and 2 g of duck egg yolk. Group C was given high-fat diet and simvastatin 0.18 mg/200 gBW. Groups D and E were given high-fat diet and papaya flower extract 125 mg/kgBW and 250 mg/kgBW, respectively. The parameter used is the histopathological description of the aorta in the form of foam cell formation. The results showed that there were few foam cell in group A. Group B had many foam cells in the tunica intima and media of aorta. Group C, D and E showed a reduction in the number of foam cells. The administration of papaya flower extract (Carica papaya L.) was effective in inhibiting foam cell formation in the aorta of Wistar rats induced by a high-fat diet, with a better effect seen at a dose of 250 mg/kgBW, which was almost comparable to simvastatin.

The extract of Carica papaya L. leaves contains phytochemical compounds such as flavonoids, alkaloids, phenolics, and saponins that play a role in biological activities, including antioxidants, anti-inflammatory, analgesic, and modulation of the nervous system. This study aims to evaluate the effects of fresh papaya leaf extract on the central nervous system (CNS) and autonomic nervous system based on varying extract concentrations. The study used test animals with treatment groups consisting of negative control, positive control, and extracts at concentrations of 4%, 8%, and 16%. Parameters observed included parasympathomimetic (PSM), parasympatholytic (PSL), sympathomimetic (SM), sympatholytic (SL), analeptic effects (ANA), CNS stimulation (SSSP), CNS depression (DSSP), and muscle relaxation (RO). The results showed that the 16% concentration produced the highest PSM activity (46.82%) and dominant CNS stimulation (38.59%), while DSSP and RO decreased at higher concentrations. This phenomenon indicates that increasing the extract concentration does not always enhance CNS depression, but rather leads to stimulation. These findings support the potential of papaya leaf extract as a neuroprotective and multifunctional agent. Further research is needed to confirm its molecular mechanisms and clinical effectiveness as a phytotherapy candidate.
