Stingless bees generally produce honey products, but there is also pollen that can be studied in melissopalinology to identify pollen morphology, type and geography of plants. Pollen can also reveal the feeding aspects of stingless bees that are useful for their survival. This study was conducted to identify the diversity of pollen used as a food source for stingless bees Trigona sp. in Sukawening Village, Dramaga District, Bogor Regency. The research method used was the extraction of pollen from honey, acetolysis, identification and calculated the percentage of pollen. The results obtained 24 types of pollen (4 species have not been identified) which belong to 19 families and the dominant source of pollen comes from herbaceous plants. The percentage of pollen collected from Trigona sp. in Sukawening Village, Dramaga District, Bogor Regency is dominated by Cocos nucifera which is 11.03% categorized as Important Minor Pollen Type (IMPT) (3-15%).

Futus is a term used by the Dawan people to refer to woven fabrics produced by the ikat technique which is applied in the yarn dyeing process. This woven cloth is one of the local pearls of wisdom passed down from generation to generation in the Dawan Tribe, North Central Timor District. The dyeing process is an important stage in the processing of woven fabrics that use plants as dyes. This study aims to reveal the types of natural coloring plants for woven fabrics, the plant organs used, and how they are processed. The semi-structured interview method was used in focus group discussions with 38 respondents who are weavers. This study revealed that there are 17 species from 12 plant families that are used as dyes for woven fabrics of the Dawan tribe in the North Central Timor District. Turmeric (Curcuma longa L.) is the most widely used plant. The part of the plant most used as a dye is the leaves, followed by rhizomes, roots, bark, fruit, and seeds. The processing of plants into dyes for woven fabrics consists of two ways, namely boiling and without boiling, each of which produces a different color with a different fixative mixture.
Futus是大湾人使用的一个术语，指的是在纱线染色过程中应用ikat技术生产的机织物。这种编织布是在北中帝汶地区的大万部落代代相传的当地智慧珍珠之一。染色过程是植物染料机织物加工的一个重要阶段。本研究旨在揭示机织物天然着色植物的种类、所使用的植物器官及其加工过程。采用半结构化访谈法对38名织工进行焦点小组讨论。本研究发现，在北中帝汶地区的Dawan部落中，有12个植物科的17种植物被用作织物染料。姜黄(Curcuma longa L.)是应用最广泛的植物。植物中用作染料最多的部分是叶子，其次是根茎、根、树皮、果实和种子。将植物加工成机织物染料有煮沸和不煮沸两种方法，每种方法用不同的固定剂混合物产生不同的颜色。

Antioxidant compounds are compounds that counteract or reduce the negative impact of oxidants, which work by donating one electron charge so that the activity of these oxidant compounds can be prevented or inhibited. The aim of this study was to determine the formula for cream variation of extract from banana peel which has the best antioxidant activity with good quality and stability of the preparation. In this study, the antioxidant cream used 3 (three) series of concentrations of the methanol extract of the skin of the plantain (Musa paradisiaca L.) fruit, namely 0.5%, 1% and 2%. The methanol extract of plantain peel was obtained by maceration method with methanol as solvent. Antioxidant cream was tested for physical quality and stability which included organoleptic test, viscosity test, pH test, homogeneity test, adhesion test, and spreadability test. The antioxidant power test was carried out using the DPPH (1,1-Diphenyl-2-Picrylhydrazyl) method using a UV-Vis spectrophotometer with a wavelength of 400-600 nm. The results of the study were further analyzed statistically using the Tukey method and one-way ANOVA. The results showed that the methanol extract of plantain peel had very strong antioxidant activity, and cream preparations could be made with various extract concentrations and the IC50 values of formula 1, formula 2 and formula 3 were 53.81 ppm, 53.29 ppm and 53.21 ppm.

Excessive sun exposure is dangerous for humans because it has many detrimental effects on the eyes, immune system as well as on the skin. Sunscreen can prevent the harmful effects of UV radiation and free radicals. Flavonoid compounds in mangosteen rind have natural sunscreen activity. The purpose of this study was to determine the physical quality and stability and activity of the ethanol extract gel of mangosteen peel in vitro with variations of carbopol 940. The extract was obtained from the maceration process using 70% ethanol. The gel was formulated using 0.1% extract and 0.5% gelling agent variations; 1%; and 1.5%. Gel test parameters including organoleptic test, homogeneity, viscosity, pH, spreadability, adhesion stability test cycling test, and sunscreen gel activity test were carried out in vitro by measuring the value of Sun Protection Factor (SPF) using UV spectrophotometry. The results showed that the 0.1% mangosteen rind ethanol extract gel formulation with variations of the gelling agent carbopol 940 0.5;1 and 1.5% had good physical quality and stability as well as sunscreen activity with an SPF value of 41,099; 39,898; 39,270 with the ultra category.
