Abstract

Stunting merupakan permasalahan kesehatan yang berdampak jangka panjang terhadap pertumbuhan fisik dan perkembangan kognitif anak akibat kekurangan asupan gizi dalam kurun waktu yang lama. Data Dinas Kesehatan Lampung Selatan (2022) melaporkan prevalensi stunting di Desa Banjar Agung, Lampung Selatan mencapai 21, 3%. Jamur tiram mengandung protein nabati yang cukup tinggi kaya vitamin B kompleks, serat, dan mineral seperti zat besi, kalsium, kalium, dan fosfor yang berperan penting dalam pertumbuhan dan perkembangan anak. Pemanfaatan bahan pangan lokal bergizi tinggi seperti jamur tiram menjadi salah satu solusi berkelanjutan dalam pencegahan stunting. Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan pengetahuan dan keterampilan ibu-ibu dan kader posyandu di Desa Banjar Agung, Lampung Selatan dalam rangka pencegahan stunting melalui edukasi dan pelatihan pengolahan jamur tiram tiram menjadi produk nutraseutika dalam bentuk pangan fungsional dari olahan jamur tiram yang dibuat menjadi nugget dan pepes jamur tiram. Kegiatan dilaksanakan dengan menggunakan metode pendekatan partisipatif yang meliputi edukasi terkait stunting dan pemanfaatan gizi jamur sebagai pangan fungsional yang berperan dalam pencegahan stunting, diskusi interaktif serta pelatihan praktek pembuatan nugget dan pepes jamur tiram. Hasil kegiatan menunjukkan adanya peningkatan pengetahuan 30 orang ibu-ibu dan kader posyandu sebesar 20 % yang ditunjukkan dari hasil evaluasi pretest dan posttest peserta kegiatan yang mengikuti kegiatan edukasi dan pelatihan. Selain bertambahnya tingkat pengetahuan, ibu-ibu dan kader posyandu juga mendapatkan ketrampilan dalam mengolah pangan fungsional olahan berbasis jamur tiram yang dihasilkan. Kegiatan ini terbukti efektif dalam meningkatkan pemahaman masyarakat mengenai pemahaman jamur tiram tiram sebagai alternatif pangan yang mendukung upaya menurunkan angka stunting.

Abstract

Crackers are a popular traditional Indonesian snack that generally has a low protein content. Fortification with natural ingredients rich in nutrients, such as Moringa leaves puree, is an alternative to increase the nutritional value of crackers. Nevertheless, the utilization of moringa leaves in food systems, particularly in Kalimantan Barat, remains relatively underdeveloped. So, this study aims to evaluate the protein content, moisture content, and sensory acceptance of crackers with various additions of moringa leaf puree. Crackers were made by adding moringa leaf puree at concentrations of 0% (control), 3%, 5%, and 7% (w/w). Protein content was analyzed using the Kjeldahl method, and moisture content was analyzed using the thermogravimetric method. Sensory acceptability, including color, aroma, taste, and texture, was evaluated using a scoring test, and overall acceptability was assessed using a hedonic test with 20 semi-trained panelists. Data analysis for protein and moisture content employed linear regression, while sensory acceptability was evaluated using One-way ANOVA. Results indicated that the addition of Moringa leaf puree tends to increase the protein and moisture content of the uncooked raw crackers, achieving R² values of 0.9715 and 0.9018, respectively, as determined by linear regression analysis. The scoring test revealed that the addition of moringa leaf puree significantly influenced all observed attributes. According to hedonic testing, crackers containing 5% moringa leaf puree were the most preferred by-panelists. This study concludes that a concentration of 5% moringa leaf puree is the recommended formula for producing crackers with enough nutritional value and favorable sensory acceptance by panelists. Keywords: crackers, moisture content, Moringa leaves puree, protein content, sensorial acceptability

Abstract

Syzygium myrtifolium leaves are plants commonly found in Indonesia and have the potential to be a source of bioactive compounds and essential oils. This article provides a brief review of the morphological characteristics, bioactive compounds, and essential oil profiles of Syzygium myrtifolium leaves from Indonesia, based on relevant scientific publications. The research method employed was a literature review of journal articles, proceedings, and bachelor’s thesis published between 2015 and 2025, retrieved from Google Scholar, ResearchGate, and Crossref. The study showed that Syzygium myrtifolium leaves have distinctive morphological characteristics, particularly changes in leaf color associated with leaf maturity. Syzygium myrtifolium leaves are reported to contain various bioactive compounds, including flavonoids, phenolics, tannins, saponins, alkaloids, steroids, and triterpenoids. Furthermore, Syzygium myrtifolium leaves produce essential oils with varying yields and volatile compound compositions. Overall, this brief literature review shows the potential of Indonesian Syzygium myrtifolium leaves as a source of bioactive compounds and essential oils for the development of products based on local resources. Keywords: bioactive compounds, essential oil, leaf morphology, Syzygium myrtifolium

Abstract

cJun NH2 terminal Kinase (JNK) merupakan protein kinase family MAPK yang berperan dalam j alur pensinyalan penyakit metabolisme, salah satunya dalam regulasi faktor resiko obesitas. Penelitian in bertujuan untuk mengeksplorasi potensi asemanan dan glukomanan dalam menghambat JNK sebagai antidiabetes.metode pendekatan molecular docking digunakan untuk mengidentifikasi interaksi antara senyawa asemanan dan glukomanan terhadap protein JNK. Asemanan dan glukomanan berikatan di sisi aktif yang berbeda satu sama lain. Residu sisi aktif asemanan berada di close gate protein JNK, sedangkan glukomanan menunjukkan sisi aktif jalur ikatan inhibitor dari JNK. Asemanan dan glukomanan menghambat aktivitas JNK dengan berikatan di sisi non-katalitik dan diprediksi penghambatan protein JNK oleh kedua senyawa secara alosterik yang dapat merubah konformasi protein JNK. Selain itu, asemanan berikatan dengan kuat terhadap protein JNK dengan jenis ikatan hydrogen, interaksi hidrofobik dan elektrostatik dengan energi ikatan yang lebih rendah dari glukomanan – JNK. Penelitian disimpulkan bahwa senyawa asemanan dan glukomanan berpotensi sebagai antiobesitas dengan peranannya sebagai inhibitor terhadap protein JNK.

Abstract

Persicaria odorata (Synonym of Polygonatum odoratum and Polygonum minus) leaves, locally known as Kesum leaves, is one of Indonesia's biodiversity species, particularly on Kalimantan Island, and it is contained a high concentration of essential oils. The extraction of essential oil from Kesum leaves commonly uses various methods, including solvent extraction, steam distillation, hydro-distillation, supercritical fluid extraction, microwave-assisted extraction, ultrasonic-assisted extraction, and so on, with various extract characteristics produced. Several studies reported that Kesum leaves essential oil has numerous advantages, including anti-bacterial, hepatoprotective, anti-tyrosinase, antioxidant properties, and so on. Future research will require additional and new techniques, particularly non-thermal extraction technology and other bioactivity tests, to improve yield and maintain the essential oil composition of Kesum leaves.

Abstract

White mulberry (Morus alba) is a plant classified into the Morus genus and the Moraceae family, growing wild or cultivated in Indonesia. The mulberry fruit is the plant part that is more utilized than others. However, white mulberry leaves are abundant and contain bioactive and nutraceutical compounds, which benefit the medicine and food sectors, making them an exciting material to investigate further. The method used in this study was a literature review, in which data from earlier studies were collected from open-access database sources, especially Google Scholar, from 2006 to 2023. The results showed that the white mulberry leaf contains rich bioactive compounds such as alkaloids, anthraquinone, anthocyanin, flavonoids, glycosides, phenolic acids, saponins, steroids, tannic acids, and so on, which are revealed to have pharmacological activities, and also contain complete nutraceutical composition as promised as food ingredients. Extraction is the primary process for extracting bioactive compounds from white mulberry leaves. Maceration, microwave-assisted extraction (MAE), soxhlet, supercritical CO2 extraction, and ultrasonic-assisted extraction (UAE) were common methods to extract bioactive compounds and produce white mulberry leaf extracts with different characteristics. Therefore, this review highlights the effect of various extraction methods on the bioactive compounds of white mulberry leaf extracts, represented by total phenolic content (TPC) and total flavonoid content (TFC).
