Abstract

Makanan jajanan sangat penting sebagai asupan gizi tambahan bagi pertumbuhan dan perkembangan anak-anak dan generasi muda. Namun permasalahannya, makanan jajanan yang banyak dijual di pasaran dan dikonsumsi oleh anak-anak dan generasi muda mengandung zat gizi yang tidak lengkap, karena lebih banyak mengandung karbohidrat dan sedikit protein, vitamin, dan mineral lainnya. Akibatnya banyak anak-anak yang mengalami stunting (gizi buruk) dan obesitas (kelebihan kalori). Hal ini disebabkan karena banyak pedagang jajanan yang menjual produk jajanannya kurang menyadari bahwa produksi jajanan yang sehat dan bergizi dapat meningkatkan nilai tambah tambah produk sehingga dapat meningkatkan harga jual produk dan dapat meningkatkan keuntungan penjualan. Selain itu, mereka juga tidak memiliki pengetahuan tentang bagaimana cara melakukan fortifikasi makanan jajanan untuk meningkatkan nilai nutrisinya. Melalui program ini, para pedagang jajanan dilatih untuk membuat berbagai macam produk jajanan yang difortifikasi dengan Spirulina, serta didampingi untuk melakukan promosi dan memasarkan produknya ke kalangan masyarakat yang lebih luas. Dalam kegiatan ini, produk jajanan yang difortifikasi dengan Spirulina adalah cendol spirulina dan dadar gulung spirulina. Pendampingan yang dilakukan oleh tim Adalah melatih cara membuat adonan yang difortifikasi serbuk Spirulina dan membantu proses pengemasan agar diminati oleh konsumen. Berdasarkan hasil dari kegiatan ini, para pedagang jajanan mendapatkan pengetahuan baru tentang manfaat Spirulina yang dapat digunakan sebagai pengganti zat warna sintetis dari produk jajanan yang mereka olah dan hal ini menjadi nilai tambahan bagi produk jajanan yang mereka produksi sehingga dapat menjadi keunggulan produk yang mereka jual dibanding produk sejenis yang telah banyak dijual di pasaran.

Abstract

The IPAS Project has a study object in the form of concrete objects and social phenomena found in nature, and it is developed based on empirical experience. This study aimed to find out various alternative study objects regarding the potential of wild mushrooms growing on oil palm empty fruit bunches (OPEFBs) piled at oil palm plantations. The research was descriptive exploratory research. Data were collected through field study, documentation, and literature study. The collected data were analyzed by using thematic analysis from Philip Marrying. The result of the field study found 12 types of wild mushrooms growing on the decayed OPEFBs. Those mushrooms were then identified based on their morphological characteristics. In this study, we found three alternative study objects towards mushrooms growing on OPEFB, which can be developed in the IPAS Project learning: (1) mushroom cultivation using OPEFB waste which includes 4 aspects (living things and their environment, substance, and their changes, earth and space, economic behavior and welfare), (2) morphological characterization for classification of mushroom including 3 aspects (living things and their environment, substance and their changes, social interaction and social dynamics), and (3) detection of chemical compounds present in mushroom, covering 3 aspects (living things and their environment, substance and their changes, economic behavior and welfare).

Abstract

Photosynthetic pigments from microalgae have great potential biotechnological applications, as healthy food colorants and cosmetics. The production of photosynthetic pigments depends on many environmental conditions, mainly light intensity during the cultivation period. The present study aimed to determine the productivity of photosynthetic pigments in the biomass of S. platensis, including total chlorophylls, carotenoids, and phycocyanin, under different light intensities: 40 µmol m–2 s–1 (lower light intensity) and 70 µmol m–2 s–1 (higher light intensity). The results showed that S. platensis culture responds to changes in light intensity by changing the composition of photosynthetic pigments as an adaptive mechanism. The higher carotenoids content (69.69 ± 7.47 µg/g dw) was found under high light intensity, meanwhile, the higher chlorophyll (1495.47 ± 279.00 µg/g dw) and phycocyanin (4995.49 ± 576.52 µg/g dw) contents were observed under low light intensity. The highest productivity of photosynthetic pigments in S. platensis was shown by phycocyanin (318.86 ± 44.22 µg/L/day) and cholophylls (95.38 ± 19.35 µg/L/day) which were produced under low light intensity. Our results show that changes in light intensity can contribute to a stronger effect on the productivity of algal pigments for human health benefits and food colorants.

Abstract

Polysaccharides are the main component in edible mushrooms and have an important role in food and medicine. Polysaccharide extraction methods and drying of mushroom simplicia are very important to obtain high polysaccharide soaks. The aim of this research was to determine the effect of adding pressure and alkali on the results of polysaccharide soaking extracted using the hot water extraction method, and the effect of different drying methods (food dehydrator and freeze drying) on the results of polysaccharide soaking. Stages in the research include: (1) collecting palm fungal biomass that grows on empty oil palm bunches, (2) preparing mushroom powder, (3) drying palm fungus biomass using a food dehydrator at a temperature of 70oC, (4) extracting dry palm fungus biomass using hot water, pressurized hot water and alkali, (5) determination of polysaccharide soak. The research results showed that the hot water extraction method without applying pressure gave a soaking yield of 3.85%, while with applying pressure the soaking yield was 8.29%. Re-extraction with the addition of alkaline solvent was able to increase the yield of polysaccharide soak by 5.08%. The research results also showed that the drying method influenced the results of the polysaccharide soak obtained. Drying with a food dehydrator was able to obtain higher soaking results (13.37%) compared to freeze drying (6.02%). Thus, it can be concluded that the oil palm mushroom simplicia which is dried with a food dehydrator and extracted using the hot water extraction method with pressure and alkali is able to increase the highest yield of polysaccharide soak. Keywords: hot water extraction, food dehydrator, freeze drying
