Abstract

Senggani fruit is an edible fruit that tastes sweet, has an attractive color, blue or reddish purple, and is thought to contain anthocyanin. The senggani fruit can be used as a source of natural dyes and is known to have active components as a source of antioxidants. This study aimed to measure the phenolic, flavonoid, and anthocyanin content and the antioxidant activity of the methanol extract of senggani fruit. Senggani fruits were extracted by maceration using methanol. The phytochemical screening test was performed. The phenolic, flavonoid, and anthocyanin content was measured using the Folin-Ciocalteu, AlCl3, and pH differential, respectively. The antioxidant activity test was carried out using the DPPH method. The phytochemical screening test showed the methanol extract of senggani fruit contained phenols, flavonoids, alkaloids, saponins, and tannins. In this study, the total phenol content was 154.880 mg GAE/g, the total flavonoid content was 6.827 mg QE/g, and the anthocyanin level was 7.516 mg/100 g. The antioxidant activity using the DPPH method showed that the methanol extract of senggani fruit had moderate antioxidant activity, with an IC50 value of 99.79 ppm.

Abstract

Indonesia's medical devices industry indicates substantial growth recently. However, domestic products are less competitive than imported products. This study tries to fill the gap by presenting a more robust analysis on the collaborative innovation process of new medical devices to support SMEs’ competitiveness through innovation and standardization. This study employed qualitative case study approach by using holistic multiple case design, namely HFNC and Dharcov-23S GLP innovation process. We have discovered the activities in the standardization process for each stage of the innovation process and the specific type of standards that SMEs should fulfill. We also capture multi-stakeholder cooperation in supporting SMEs in each activity. As result, the role of multi-stakeholder collaboration is highlighted in supporting SMEs along the innovation and standardization process to gain market competitiveness. Actors involved in each innovation process activity have disparate backgrounds, capabilities, and knowledge, such as PRI, industry, government (Public testing laboratory, National Public Procurement Agency, MoH), medical experts, hospitals, and users.

Abstract

Abstract. The strategy for utilizing research results through collaboration between stakeholders is crucial in developing agricultural innovation system. This study examines the multi-stakeholders collaboration on the scaling process of the Jajar Legowo (Jarwo) Super technological package as the research result of the Agricultural Research and Development Agency (Balitbangtan), Ministry of Agriculture (MoA), Indonesia. Employing the innovation platform framework, this study explores the multi-stakeholders’ perspectives by conducting semi-structured interview with related stakeholders: researchers, policy makers, disseminators, and local governments. The innovation platform framework is applied to map the actors, roles and functions that support the scaling process along the value chain from the problem identification, towards technology development through experimentation and the upscaling process in the system. The study finds that the innovation platform succesfully improve the rice productivity in some regions despite some challenges. Instead of full technology application, farmers prefer integratge them with indigenous practice due to the limited absorptive capacity, socio-economic background and natural conditions of the region. Also, the findings highlight the gap in multistakeholder relation despite the central rolef of the central government that not only act as a policy maker but also technlogy developer, disseminator, and logistic providers. The goverment is suggested to enhance the institutional arrangements by engaging industry in input logistic system to provide farmers’ access on technology supply and integrate policoes/programs with the local government and  other related stakeholders to accelerate the upscaling process.

Abstract

Penyakit mulut merupakan salah satu penyakit tidak menular (NCD) yang paling umum terjadi di seluruh dunia, dan mempengaruhi sekitar 3,5 miliar orang. Penyakit mulut utama ini mempengaruhi hampir 480 juta orang (43,7% dari populasi) pada tahun 2019. Karies gigi adalah NCD yang paling umum di seluruh dunia, dengan lebih dari sepertiga populasi global hidup dengan karies gigi yang tidak diobati. Penyebab utama adalah bakteri Streptococcus mutans. Penelitian ini bertujuan mengevaluasi aktivitas antibakteri ekstrak Fibraurea tinctoria Lour dalam pasta gigi herbal terhadap S. mutans dengan desain penelitian eksperimental laboratorium. Metode difusi cakram Kirby-Bauer digunakan untuk mengevaluasi aktivitas antibakteri, sementara sifat sensorik dan fisikokimia pasta gigi dievaluasi. Hasil menunjukkan bahwa pasta gigi dengan ekstrak etanol akar kuning pada konsentrasi 3,125% dan 6,250% memiliki aktivitas antibakteri yang signifikan, dengan zona hambat rata-rata 19,36 mm dan 11,04 mm, sedangkan konsentrasi 0,3125% tidak menunjukkan aktivitas hambatan. Penggunaan bahan pengikat CMC-Na pada konsentrasi 3% dan 5% memenuhi standar kualitas, sementara pada 1% tidak memenuhi uji viskositas. Hasil ini menunjukkan potensi pengembangan pasta gigi herbal sebagai alternatif yang efektif dalam mengatasi masalah karies gigi, dengan mengurangi ketergantungan pada produk berfluorida yang berpotensi menimbulkan efek samping.

Abstract

Oxidative stress has long been associated with increased risk for several diseases. Antioxidant is a molecule that inhibits the oxidation of other molecules and delays or prevents oxidative damage. Natural phenolic and flavonoid compounds are plant secondary metabolites directly contributing to antioxidant activity. Fibraurea tinctoria Lour, often called the yellow root, is a plant that has long been known in the traditional medicine of the native tribes of West Kalimantan to treat several diseases, including malaria, jaundice, and diabetes. This study aimed to quantify the total phenolic (TPC) and flavonoid (TFC) contents and antioxidant activity of the ethanol extract of yellow root stems. Yellow root stems were extracted by maceration in 96% ethanol for four days. The total phenolic, flavonoid, and antioxidant activities were measured using the Folin-Ciocalteu, AlCl3, and DPPH methods. Phytochemical screening showed that the ethanol extract of yellow root stems contains phenolics, flavonoids, alkaloids, saponins, tannins, and steroids/triterpenoids. The total phenol and flavonoid contents were 40.2 mg GAE/g extract and 61.2 mg QE/g extract, respectively. The ethanol extract of yellow root stems showed moderate DPPH scavenging activity, with an IC50 of 152.13 ppm. From this study, it can be concluded that this plant could be a potential source of natural antioxidants.

Abstract

The Jarwo Super innovation platform is identified as a framework for introducing Jarwo Super rice cultivation technology through the use of technological components developed for irrigated rice fields. This research examines the determining factors for the success of the collaboration process in producing agricultural innovation resulting from research and development in Indonesia. Using an innovation platform framework, this research conducted semi-structured interviews with relevant stakeholders, including researchers, policy makers, information disseminators, and local governments, to investigate multi-stakeholder perspectives. The Multi Channel Dissemination Structure (SDMC) of the Agricultural Research and Development Agency, which was created as a policy scheme starting with research, assessment, development, and application and feedback on technology, depicts actor collaboration. The findings of this study highlight the importance of three elements—demand-based participation (innovation evolution), capacity building, and commitment—for achieving multi-stakeholder collaboration. The first component, demand-based participatory, consists of implementation procedures, testing, evaluation, and research. further, the capacity building component indicates that a platform for experimentation, learning, and knowledge development is necessary for successful collaboration. The third factor is commitment which aims to encourage new developments, where the innovation platform can be a solution according to needs based on goals and vision and as a form of legitimacy for the innovation produced. We suggest that these factors can be of interest for practical application by experts to minimize uncertainty in innovation outcomes and increase the effectiveness of decision making.
