Salted fish is one of the processed fish products that are in great demand by the people of Indonesia. This type of preparation has good durability with natural processes. However, there are some cases that use chemicals as preservatives, such as formaldehyde. This study aims to determine the formaldehyde content in salted fish that is traded in the market in Indonesia. This research is descriptive and the sample is taken from Ciroyom Market, Bandung City, Indonesia, randomly. Samples were analyzed qualitatively to observe the physical characteristics of salted fish. In addition, quantitative analysis was also carried out to determine the level of formaldehyde present in salted fish using a UV-Vis spectrophotometer at a wavelength of 520 nm. The results of the analysis showed that 4 of the 15 samples tested contained formaldehyde with a concentration of 0.033 – 0.482 ppm. The characteristics of these samples physically also have similarities with the characteristics of fish containing formaldehyde, namely bright white and hard textured.

The use of traditional medicines holds a great promise as an easily available source as effective medicinal agents to cure a wide range of ailments among the people particularly in tropical developing countries like India. The present study investigates the qualitative and quantitative analysis of the major bioactive constituents of N. crenulata leaf extracts. The extractive values of aqueous, acetone and chloroform extracts were found to be 11.34, 4.24 and 6.06 respectively. Qualitative phytochemical analysis of these three solvent extracts confirm the presence of Alkaloids, Saponins, Flavonoids and Phenolic compounds in all the three extracts; however, these phytochemicals were more significant in aqueous extract. Quantitative analysis was carried out using TLC method by different solvent system. Amongst various solvent systems, Butanol: acetic acid: water (9: 0.9: 0.1 v/v/v) shows maximum resolution and number of spots produced at long UV (365 nm) and under iodine vapours. The TLC chromatograms constituted different coloured phytochemical compounds with different Rf values. It can be conveniently used to evaluate the quality of different area samples. This indicates that the leaves can be useful for treating different diseases because the therapeutic activity of a plant is due to the presence of particular class of compounds and thus can serve as potential sources of useful drugs in future.

Ronggeng Pasaman is a performance art consisting of pantun, joget, and music, especially in Simpang Tonang, Pasaman, West Sumatra. The form of the Ronggeng Pasaman show is combining bouncing skills while dancing to the accompaniment of violin and drum music. The show starts at night, and ends until early morning. Currently Ronggeng Pasaman has undergone a transformation, people, especially young people, are less interested and begin to leave their regional arts, so the Ronggeng Pasaman show is rarely displayed. There was anxiety from the artists themselves, then initiatives emerged to attract the attention of the people. So it formed the Ronggeng Pasaman Ganto Saroha group, with the addition of keyboard music instruments in the show. Unlike the Pasaman Ronggeng Performance in general, the Ganto Saroha group does not show male singers with female appearance, but rather singers are real women or men. This study uses qualitative methods, is analytic description, observant participants. The results showed that the transformation carried out by the artists, made the Ronggeng Pasaman performance of the Ganto Saroha group well received and in great demand by all people in Pasaman, and was fully supported by the local government.</em></p><p><strong><em>Keywords : </em></strong><em>Form Transformation, Pasaman Ronggeng Performance, Ganto Saroha Group</em></p><p align="center"><strong><em>Abstrak</em></strong></p><p><em>Penelitian ini bertujuan untuk mengetahui transformasi bentuk pertunjukan Ronggeng Pasaman grup Ganto Saroha di Kecamatan Duo Koto, Kabupaten Pasaman.

The Village

The freshwater fishery sector is one of the potentials possessed by the village of Tapen due to its location near the river and the Sampean Baru dam, which is the largest river in Bondowoso Regency. However, the income of the people with the livelihood of freshwater fish fishermen in Tapen Village is not optimal because the community does not understand how to process and market processed freshwater fish products in order to increase the selling value of fish. Efforts to increase community income through the fisheries sector carried out by the 60 KKN BBM Uniar period eke-63 are socialization of processing and marketing of processed freshwater fish products. The activity was carried out with a presentation method regarding the processing and marketing of processed freshwater fish products as well as a demonstration on the process of making processed freshwater fish products in the form of catfish dumplings and tilapia nuggets. The socialization participants were PKK women, village cadres, fishermen's wives, and prospective entrepreneurs from the village of Tapen. In addition, the socialization regarding the marketing of processed freshwater fish products was also carried out using the online method using the Whatsapp group media.AbstrakSektor perikanan air tawar merupakan salah satu potensi yang dimiliki oleh desa Tapen disebabkan letaknya yang berada di dekat sungai dan bendungan Sampean Baru yang merupakan sungai terbesar yang berada di Kabupaten Bondowoso. Namun, pendapatan masyarakat dengan mata pencaharian nelayan ikan air tawar di Desa Tapen belum maksimal karena masyarakat kurang memahami cara mengolah dan memasarkan produk olahan ikan air tawar guna meningkatkan nilai jual ikan. Upaya untuk meningkatkan pendapatan masyarakat melalui sektor perikanan yang dilakukan oleh kelompok 60 KKN BBM Uniar periode ke-63 adalah dengan Sosialisasi Pengolahan dan  Pemasaran Produk Olahan Ikan  Air  Tawar.  Kegiatan yang dilakukan dengan metode presentasi mengenai pengolahan dan pemasaran produk olahan ikan air tawar serta demonstrasi mengenai proses pembuatan produk olahan ikan air tawar yang berupa siomay ikan lele dan nugget ikan nila.

ABSTRACT The prevalence and numbers of Listeria monocytogenes in various categories of ready-to-eat (RTE) food products taken from retail outlets and food industries over a 5-year period are presented. A total of 30,016 RTE food samples were analyzed for L. monocytogenes prevalence, and 3.6% were found to be positive. The highest prevalence was found for RTE fish and fish products (11.6%), especially for lightly salted and cold-smoked fish products. The overall prevalence of L. monocytogenes in other food categories was low, within the range of 0 to 3.9%. In addition, 14,342 RTE food samples were analyzed to determine the numbers of L. monocytogenes. A food safety criterion of 100 CFU/g was exceeded for 0.3% of RTE food samples. Samples most often exceeding the legal safety limit were from the RTE salted and cold-smoked fish product categories. High prevalence, 28.6 and 26.5%, respectively, and high numbers of L. monocytogenes among salted fish and cold-smoked fish products indicate a risk of listeriosis, especially for susceptible risk groups. The results of the current study can be used at both the national and the international levels to update the perception of the L. monocytogenes risk deriving from RTE foods. HIGHLIGHTS

African Intellectuals

In 1930, the same year in which the segregationist Land Apportionment Act was passed, the governor of Rhodesia addressed a meeting of representatives from the various missionary organizations operating in the colony. He proceeded to argue against the sort of education that might create a class of African intellectuals who would eventually challenge white economic and political dominance:The nature of the intellectual advance to be aimed at should be one of which advantage can be taken in the ordinary daily lives of the people, and should be a step forward in a field already familiar to them, rather than a violent transition into fields which belong to a different type of civilization. As the life of African peoples is to a preponderating extent agricultural, education should aim at making them better agriculturalists and better able to appreciate all the natural processes with which agriculture is connected.

AbstractBiodiversity is not exclusively a product of pristine natural processes but is also, to a considerable degree, caused by human activities. This is demonstrated by a detailed inspection of the use and classification of plants by the people of Nokopo village in the Finisterre Range of Papua New Guinea. Nokopo people recognise and value biodiversity on all its levels - genetic diversity, species diversity and diversity of ecosystems - and their activities enhance overall biodiversity. This can be partly explained by the usefulness biodiversity has to them, in terms of resource access and other utilitarian considerations. On the other hand, aesthetic concepts and values make a significant contribution. Both these intrinsically interwoven components - the utilitarian and the aesthetic component respectively - form the base for understanding the major role humans play in creating and maintaining biodiversity, the role of keystone species enhancing overall biodiversity in a given ecosystem.

The conditions for nitrite reductase (NiRs) produced by Lactobacillus plantarum from salted fish were optimized. Enzyme activity of nitrite reductase was used as evaluation index. The results showed that the pH value had greatest influence on enzyme activity. The optimum conditions of producing nitrite reductase were inoculate quantity 4 %, pH 6.3, culture temperature 35 °C, incubation time 48 h. The enzyme activity of nitrite reductase reached to 89.672 U/mL, which increased by 71 % after optimization. This work provided the foundation for the research of enzymatic properties of nitrite reductase. This may be useful to the production of salted fish products.
