Abstract

Cascara is coffee pulp which contains caffeine, chlorogenic acid and phenolic compounds, but has not been utilised optimally. Cascara can be processed into ready-to-drink cascara kombucha products, which are beneficial for the body. This research aims to determine the effect of adding coconut water (Cocos nucifera L.) and red dragon fruit (Hylocereus polyrhizus) on the alcohol content, total phenolics, caffeine, minerals, antioxidant activity and sensory hedonic content of ready-to-drink cascara kombucha. This research method was carried out in 3 stages including optimizing fermentation time and SCOBY starter concentration based on pH value; fortification ratio optimization; and product analysis includes alcohol content by dichromate method, total phenolics by Folin-Ciocalteu method, caffeine by UV-VIS spectrophotometry method, minerals by AAS spectrophotometry method, antioxidant activity by DPPH method, and sensory hedonic. The research results showed that the best time was 12 days, pH value 3.42 at 10% SCOBY starter concentration. The ratio of cascara kombucha : fortificant is 1:1 resulting in an alcohol content of 0.23-0.43%. The highest levels for total phenolics, caffeine, and minerals were 656.32 mg/kg; 35.53 ppm; and 732.83 mg/100g respectively. The highest antioxidant activity was obtained from the red dragon fruit fortified cascara kombucha product with a yield of 89.69%. The highest color and aroma attributes were obtained from the cascara kombucha product fortified with a mixture of coconut water and red dragon fruit, while the highest value for the taste attribute was obtained from the cascara kombucha product fortified with red dragon fruit.

Abstract

Yogurt is a drink resulting from fermented milk using lactic acid bacteria. Yogurt production using Etawa goat's milk (Capra aegagrus hircus) was chosen because its nutritional content is quite good and low in lactose. The addition of avocado (Persea americana mill.) flesh to yogurt is expected to increase antioxidant activity and vitamin E levels. This research aims to produce goat's milk yogurt with the addition of avocado flesh as a functional drink that is liked by consumers, has antioxidant activity, and has high levels of high total phenolics and rich in vitamin E. The method used in this research includes the production of yogurt without the addition of avocado flesh as a control yogurt and yogurt with the addition of avocado in various variants. Then sensory analysis was carried out using the hedonic test, analysis of total phenolic content using the Follin-Cicocalteu method, analysis of antioxidant activity using the DPPH method and analysis of vitamin E levels using a spectrometer. The research results showed that the control yogurt was white in color, in the form of a thick, semi-solid liquid, had a distinctive smell, a sour taste, a homogeneous consistency and had a pH value of 4.3–4.8. The results of the sensory analysis test of yogurt with the addition of 20% avocado flesh (Y1) was the product most preferred by the panelists based on the color and aroma attributes, while for the texture and taste attributes the panelists preferred 40% (Y2). The total phenolic compound, antioxidant activity, and vitamin E test results of goat's milk yogurt reached 91.2%, the more avocado flesh was added, the yogurt with the addition of avocado flesh increased significantly with the addition of avocado pulp concentration

Abstract

The availability of food sources is very important for stingless bee farmers in Sungai Tiung Village, Banjarbaru City. Pollen is a food source that contains protein, vitamins, fats, and minerals that are important for bees. Pollen identification can be an indicator of the types of plants that bees feed on. This study aims to identify the types of pollen found in Heterotrigona itama nests and analyze each pollen category based on pollen percentage. The research was conducted at three different locations: Cempaka Kelulut, Cempaka Beton, and Kelulut Kalimantan. Samples were collected using purposive sampling. The acetolysis method was used as an indicator to identify pollen types. Pollen was identified by comparing and matching the observed characteristics with images or literature from identification guides, journals, and research theses. Based on the research results, the types of pollen found in Heterotrigona itama nests at the three meliponine beekeeping locations in Sungai Tiung Village were highly diverse. The pollen originated from 18 plant species and 13 plant families. Based on the percentage at Cempaka Beton, the dominant pollen is Scoparia dulcis (40%) and Phyllanthus urinaria (27.5%) as secondary pollen. At Cempaka Madu Kelulut, Phyllanthus urinaria is the predominant pollen (57%), while at Kelulut Kalimantan, Mimosa pudica dominates with (53.1%)

Abstract

Amethyst (kecubung) merupakan salah satu batu mulia yang banyak ditemukan di Kalimantan Selatan dan memiliki nilai ekonomis serta estetika tinggi. Penelitian ini bertujuan untuk mengkaji karakterisasi sifat fisik batu Amethyst melalui studi literatur dari 10 artikel ilmiah yang terbit dalam kurun waktu 2015–2025. Fokus kajian meliputi struktur kristal, kekerasan, densitas, sifat optik, serta respons terhadap perlakuan termal. Berdasarkan hasil analisis, Amethyst diketahui memiliki struktur kristal trigonal, kekerasan 6,5–7 skala Mohs, dan densitas antara 2,63–2,66 g/cm³. Warna ungu khasnya disebabkan oleh pusat warna akibat ion Fe³⁺ dan Fe⁴⁺ yang menyerap pada panjang gelombang 360 nm dan 545 nm. Teknik karakterisasi seperti XRD, UV–Vis, FTIR, Raman, dan Mössbauer terbukti efektif untuk mengungkap sifat fisik dan optik Amethyst. Perlakuan panas pada suhu 400–600°C terbukti menyebabkan perubahan warna dan struktur mikro yang bersifat ireversibel. Hasil kajian ini diharapkan dapat menjadi referensi dalam klasifikasi batu mulia lokal serta mendukung pemanfaatan sumber daya mineral secara berkelanjutan, khususnya di Kalimantan Selatan.

Abstract

The use of synthetic soaps containing harmful ingredients has driven consumers toward natural soap alternatives. Transparent soap offers the advantage of producing a softer lather and containing moisturizing agents that help prevent dry skin, making the development of transparent soaps with natural active ingredients essential for maintaining skin health and beauty. This study aimed to develop a transparent soap formulated with bangkal wood bark (Nauclea subdita) extract, a native plant of South Kalimantan rich in secondary metabolites such as alkaloids, flavonoids, polyphenols, and saponins. Previous studies have reported that these compounds possess natural antioxidant and sunscreen properties, as well as anti-inflammatory, antiplasmodial, antipyretic, and antimicrobial potentials. The methodology included reflux extraction using 96% ethanol, soap formulation through saponification, and comprehensive quality evaluation. Tests conducted included measurements of water content, pH, chloride content, ethanol-insoluble matter, free fatty acids/alkali, total fatty matter, unsaponified fat, foam stability, and organoleptic properties. The results showed that the transparent soaps with bangkal wood bark extract met the SNI 3532:2021 standards for water content, pH, ethanol insoluble matter, chloride content, foam stability, and total fatty matter across all extract concentrations. However, soap D (6 grams extract) exceeded the acceptable limit for free fatty acids. Organoleptic evaluation indicated that all formulations were well accepted by the panelists. Therefore, the bangkal wood bark extract demonstrates strong potential as a natural active ingredient for developing transparent soap formulations that meet quality standards.
