Abstract

Flacourtia inermis fruit, locally known as lobi-lobi fruit, is one of Indonesia's rare local fruits, rich in nutritional and bioactive compounds. However, the physical-chemical characteristics, bioactive composition, bioactivity, and food innovations based on the lobi-lobi fruit have not yet been comprehensively explored. So, the objective of this article is to provide a comprehensive overview of the physical-chemical characteristics, bioactive composition, bioactivity, and food innovations based on the lobi-lobi fruit, as per earlier studies. The approach used in this study is a narrative literature review, with data sources comprising earlier publications, including articles and scientific proceedings from 2011 to 2025, that are relevant to the topic under discussion. The review findings revealed that fresh lobi-lobi fruit is characterized by its high moisture, fat, and vitamin C content, as well as its richness in various phytochemical compounds, including tannins, saponins, flavonoids, phenolics, triterpenoids, alkaloids, and anthocyanins. Numerous studies have demonstrated that lobi-lobi fruit and its extracts exhibit significant bioactivities, such as antioxidant, antibacterial, antidiabetic, anti-hypertension, acting as a lipase enzyme inhibitor, and a remedy for dyslipidemia. Innovations deriving from lobi-lobi fruit include the production of vinegar and wine, alongside its application as a natural preservative for fishery products and a flavoring agent in food products. Looking ahead, there is considerable potential for lobi-lobi fruit to be utilized for fortification and supplementation in food products, as well as being processed into powder form through drying to enhance its shelf life and accessibility. Keywords: bioactive, bioactivity, food innovation, lobi-lobi fruit, physicochemical characteristics

Abstract

Porang is rich in glucomannan, making it valuable in food and non-food applications, often processed into porang flour. Size reduction of porang flour into porang powder is a crucial stage to meet the particle size standard of commercial konjac powder.  However, this stage is rarely explored, especially when using a roller mill machine.  This study aims to evaluate the performance of a batch roller mill machine on the particle size and colour of porang powder with various porang flour masses. The mass of porang flour used in this study was 100, 200, and 300 g, which were coded M100, M200, and M300, respectively, and the results obtained were analyzed descriptively. The particle size distribution was assessed using a particle size analyzer CILAS 1090-dry method, and colour was observed using the Colour Reader Minolta CR-10. The results showed that different mass variations of porang flour produced different particle size distribution patterns in the porang powder produced. Mathematically, the parameters d10, d50, d90, and the average diameter of porang powder follow an exponential equation as a function of the increasing porang flour mass, with R2 values ranging from 0.97 to 0.99. In addition, the average diameter of porang powder from treatment M100 was 68.81 µm and met the average particle size of commercial konjac powder. The colour  L* and degree of whiteness (DoW) of porang powder decreased linearly as a function of the increasing porang flour mass, while the a* and b* values increased logarithmically, with R2 values more than 0.99.
EFEK FORMULASI TEPUNG GAPLEK, TEPUNG UBI JALAR KUNING, DAN TEPUNG LABU KUNING TERHADAP PENERIMAAN SENSORIS LAKU TOBE MODIFIKASI Naisali, Hyldegardis; Utoro, Panggulu Ahmad Ramadhani; Permatasari, Nelsy Dian; Witoyo, Jatmiko Eko

Abstract

Laku tobe merupakan makanan tradisional dari Nusa Tenggara Timur yang disajikan pada acara adat tertentu, dan umumnya dibuat dari tepung gaplek. Penelitian ini mengembangkan laku tobe modifikasi dengan 3 bahan utama, sebagai faktor independen, yaitu tepung gaplek, tepung ubi jalar kuning, dan tepung labu kuning dengan 4 respon utama, meliputi penerimaan aroma, rasa, tekstur dan warna menggunakan metode hedonik dengan skala preferensi 1-5. Rancangan penelitian yang digunakan dalam penelitian ini adalah D-optimal Mixture Design dengan kisaran untuk tepung gaplek (40-50 gram), tepung ubi jalar kuning (30-40 gram), dan tepung labu kuning (20-30 gram). Semua p-value dari tiap respon dianalisis menggunakan analisis ragam (ANOVA) pada software Design Expert 13 untuk menentukan ada tidaknya efek faktor independen terhadap respon. Selain itu, laku tobe modifikasi terbaik tiap respon dipilih berdasarkan skor penerimaan tertinggi dan dibandingkan dengan laku tobe tradisional menggunakan uji-t berpasangan. Hasil penelitian memperlihatkan bahwa semua jenis tepung yang digunakan tidak berpengaruh nyata (p > 0,05) terhadap penerimaan sensoris laku tobe modifikasi. Penerimaan sensoris aroma,  rasa, tekstur, dan warna dari laku tobe modifikasi sebesar 3,16-3,66, 3,16-3,78, 3,06-3,48, dan 3,18-3,74 secara berurutan.  Perlakuan terbaik dari laku tobe modifikasi pada setiap respon ditemukan pada run formulasi yang berbeda. Lebih lanjut, hasil komparasi laku tobe modifikasi terbaik dari tiap respon berbeda nyata (p < 0,05)  dengan laku tobe tradisonal pada parameter penerimaan sensoris aroma, tekstur, dan warna, serta tidak berbeda nyata (p > 0,05)  dengan parameter penerimaan sensoris rasa.

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.
