Kesehatan adalah salah satu berkah yang sangat berharga dalam kehidupan. Kondisi pandemi Covid-19 telah melahirkan budaya 3M dalam kehidupan sehari-hari, yaitu memakai masker, menjaga jarak dan mencuci tangan. Mencuci tangan menggunakan handsanitizer merupakan cara yang praktis untuk membunuh mikroorganisme. Namun, handsanitizer yang tersedia di pasaran memiliki variasi bahan baku yang mengandung Alkohol 96% dan peroksida. Pemakaian yang sering dan dalam jangka waktu yang lama dapat memberikan efek samping iritasi pada kulit tangan. Selain itu, upaya lain untuk menjaga kebersihan lingkungan dapat dilakukan dengan menggunakan larutan desinfektan. Larutan ini dapat membebaskan lantai, dinding rumah, peralatan rumah tangga, dan udara sekitar dari mikroorganisme. Namun, desinfektan umumnya mengandung komponen kimia yang sangat korosif. Oleh karena itu, kondisi ini mendorong pencarian sumber bahan ramah lingkungan. Pelatihan ini bertujuan untuk meningkatkan kesehatan masyarakat Teluk Batang secara mandiri melalui pembuatan handsanitizer dan desinfektan berbasis eco-enzyme dari limbah sayuran dan buah. Eco-enzyme dibuat dari  5kg  sampah campuran sayur dan buah yang difermentasi selama 3 bulan, dihasilkan cairan enzim sebanyak 9 kg  dan ampas fermentasi sebanyak 6 kg. Kemudian, handsanitizer diproduksi menggunakan rasio 10% : 40% dengan mencampur 100 mL eco-enzyme dan 400 mL air bersih. Sedangkan larutan desinfektan dibuat menggunakan rasio 50% : 50% dengan mencampur 250 mL eco-enzyme dan 250 mL air bersih. Produk yang dihasilkan kemudian diberi label dan dapat digunakan langsung oleh peserta pelatihan.

Free radicals contribute to human health problem resulting in various human diseases, including central nervous system injury, cancer, inflammations, and the decrease of organ function related to oxidation. This condition has encouraged the effort of finding new natural antioxidant and anti-inflammatory sources. Macroalgae act as excellent natural resources due to their bioactive potential with diverse applications in various fields. Eucheuma cottonii belonging to Rhodophyceae grow abundantly along Lemukutan Island waters, however, their existence has not been exploited. This study aims to evaluate antioxidant and anti-inflammatory activities of ethanol extract of E. cottonii from Lemukutan Island waters, West Kalimantan. The observation of antioxidant activity was done using the method of DPPH (1,1-diphenyl-2-picrylhydrazyl) with UV-vis spectrophotometer, while anti-inflammatory acyivity activity was determined using the RBCs membrane stability method. The ethanolic extract of E. cottonii had potential antioxidant activity with IC50 of 127.75 ppm and was classified as moderate category. Extracts showed also anti-inflammatory acyivity activity with the concentration of 219.83 ppm. Red macroalgae E. cottonii can be used as potential natural antioxidant and anti-inflammatory agent.

Ale-ale are popular clams in the coastal area of Ketapang. The local community uses the clams as food, one of which is in the form of fermented products. In the fermentation process, the nutritional content of course will be different from fresh ale-ale because it has gone through the preservation process. One of the goals of processing it into fermented products is to increase the product's durability. Essential mineral contents (Fe, Mn, Zn) in fermented products is different and tends to decrease. Essential mineral testing used the Atomic Absorption Spectroscopy (AAS) method. The water content and ash content of fresh ale-ale were 63.1% and 15.8%, respectively. While the water content and ash content of the fermented ale-ale were 68.69% and 17.2%, respectively. The essential mineral contents of fresh ale-ale obtained Fe 23 mg/kg, Zn 1.70 mg/kg and Mn 0.138 mg/kg. In fermented ale-ale, the content of Fe is 9.76 mg/kg, Zn is 0.740 mg/kg and Mn is 0.387 mg/kg.

Lemukutan Island in West Kalimantan has marine natural resources with a high level of diversity such as seagrass, coral reefs, macroalgae, and gastropods. Gastropods are one of the largest Mollusc phylum groups that are abundant in the waters of Lemukutan Island. Several types of gastropods have been reported to have high economic value and high nutritional content as well as macro minerals such as Na, Ca, K, F, and P. Therefore, these biota are more widely used as food. This study aims to analyze the proximate and mineral content of gastropods (Lambis and Monetaria) from the waters of Lemukutan Island. The moisture content and ash content of the sample were determined by the gravimetric method. The results of the study found that macro mineral content was determined in Lambis and Monetaria by Atomic Absorption Spectrophotometer (AAS). The protein content in both types of gastropods is quite high. Monetaria has a higher protein content (63.69%) than Lambis (50.06%). However, the fat content in Lambis is 1.88% and Monetaria is 1.14%. The highest mineral content of these two types of gastropods is iron (Fe). Lambis and Monetaria have Fe content of 0.2762 mg/kg and 0.1818 mg/kg, respectively.
