This research aims to analyze the production process of salted layur fish and its organoleptic quality in Pangandaran Regency, West Java, Indonesia. This research was conducted from 10 February 2023 to 10 March 2023. The research method used was a survey method. The research procedure was carried out in two stages. The first stage observed the process of making salted layur fish products and the second stage tested the organoleptic quality of the salted layur fish it produced. Analysis of the production of layur salted fish was carried out by observing production sites and interviewing workers and business owners. Organoleptic quality testing is done by scoring test . The format for the scoring test is shown in Table 1. Observations on the production of salted layur fish were centered in Parapat Hamlet, RT 5 RW 9, Katapang Doyong Field, Pangandaran Village, Pangandaran District, Pangandaran Regency, West Java. Astronomically the research location is at 7°41'26.1" South Latitude and 108°39'47.6" East Longitude. The data obtained were analyzed descriptively . Based on research results, it was found that the process of making layur salted fish in Pangandaran-West Java includes stages of fish preparation, salting , drying, and storage. Organoleptic quality indicates that the resulting salted layur fish is of good quality and is suitable for consumption according to the Indonesian National Quality Standards with an average value of 8.8.

Pollen analytical study of two locally produced honey samples collected from Akwa Ibom and Cross River State, Southern Nigeria were carried out in order to ascertain the preferentially foraged plants by honey bees, as well as the concentration of heavy metals. Samples were subjected to standard laboratory procedures using an acetolysis mixture (pollen analysis) and atomic absorption spectrometry (heavy metals). The results from the analysis revealed 32 taxa belonging to 17 botanical families. The number of pollen grains in the honey samples varied significantly (between 4,887 - 12,755 pollen grains), indicating their richness in pollen grains. 12 elements - Ni, Cu, Zn, Se, Br, K, Ca, Ti, Cr, Mn, Rb, and Fe were detected. Potassium had the highest concentration, followed by iron, calcium, titanium, zinc, copper, chromium, nickel, among others. What is more, in this study, some important honey plants: Spondias mombin, Daniella oliveri, Manihot esculenta, Treculia africana, Syzigium guineensis, Diospyros mespiliformis, Parkia biglobosa, Terminalia superba, Senna hirsuta, among others were found to be predominant and have been identified to be characteristic of the vegetation typical of Southern Nigeria. With regard to honey, this study gives an indication of the geographical and botanical origins, as well as types, source, and degree of contamination, and also an overall measure of honey purity. Such information, when displayed, can help consumers make informed decision when purchasing honey and will also help beekeepers to avoid possible contamination. Moreover, it will assist regulatory agencies in taking proper measures for environmental and consumer protection, since the concentration of heavy metals in honey is influenced by environmental pollution.
