Abstract

West Timor Island is one of the islands in East Nusa Tenggara Province, which has a dry climate and rocky geographical area, with corn as the main commodity. Corn is a staple food and ingredient to produce various traditional ethnic foods. “Jagung katemak” is one of the traditional ethnic foods made from local corn combined with various vegetables, legumes, and other spices, using simple methods and paying attention to local wisdom. However, a comprehensive and in-depth exploration of its history, constituent composition of ingredients, and the traditional processing of “jagung katemak” is still infrequent. This paper aims to uncover the history, composition of ingredients, and the traditional processing of “jagung katemak” from various sources, including books, scientific journals, and local news relevant to the topic discussed.  The study's results show that the history, composition of ingredients, and traditional processing of “jagung katemak” have been successfully revealed in detail and depth.  In addition, the challenges and prospects of developing katemak corn in the contemporary era are also comprehensively reviewed. Hopefully, “jagung katemak” can be nationally and internationally recognizable by highlighting local wisdom.

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

Daun pedada (Sonneratia caseolaris) merupakan bagian tanaman mangrove Indonesia yang kaya metabolit sekunder dan berpotensi tinggi sebagai sumber bahan aktif alami, namun informasi terstruktur mengenai morfologi, fitokimia, teknik ekstraksi, dan aplikasinya masih tersebar di berbagai publikasi. Artikel ini bertujuan menyajikan telaah pustaka komprehensif tentang karakter morfologi daun pedada, komposisi senyawa bioaktif, pengaruh jenis dan kondisi ekstraksi terhadap kandungan fenolik–flavonoid serta aktivitas antioksidan, dan ragam aplikasi pangan maupun non pangan yang telah dikembangkan di Indonesia. Metode yang digunakan adalah tinjauan literatur sistematis terhadap artikel jurnal nasional terakreditasi dan karya peneliti Indonesia periode 2015–2025, yang diperoleh melalui basis data open access dengan kata kunci terkait daun pedada, kemudian dianalisis secara deskriptif. Hasil telaah menunjukkan bahwa daun pedada memiliki profil fitokimia yang kaya (fenolik, flavonoid, tanin, saponin, terpenoid, steroid, triterpenoid) dengan aktivitas antioksidan kuat yang sangat dipengaruhi oleh jenis pelarut dan teknik ekstraksi, serta telah diaplikasikan sebagai bahan tambahan pangan bioaktif, permen jelly, dan terutama sebagai bahan aktif fitokosmetik (face mist, tabir surya, masker, lulur) dengan dukungan data keamanan awal yang menjanjikan. Temuan ini menegaskan bahwa daun pedada merupakan kandidat penting untuk pengembangan pangan fungsional dan produk fitokosmetik tropis berbasis sumber daya mangrove Indonesia.
