Brachiopods are a group of ancient marine invertebrates that are still found today, so they are known as "living-fossil". The purpose of this study was to determine reproductive biology through sex ratio approach, gonad maturity stages, body mass weight and growth pattern of L. anatina through size distribution approach, length-weight relationship, and condition factors. This research was conducted from April to December 2021, at the Aceh northern shore. The method used in this research is purposive sampling. The results showed that based on the morphological characteristics, only one species of brachiopods from the class Lingulata was found, namely Lingula anatina Lamarck, 1801. This species has an unequal sex ratio. Analysis of Body Mass Weight (BMW) and Gonado Somatic Index (GSI) shows an inverse relationship where the BMW value is lower than the GSI value. The condition factor of L. anatina also fluctuates every month, this is presumably due to availability of food in habitat. Gonad maturity stages of L. anatina at the locations of Syiah Kuala and Alue Naga were in spawning conditions (stages IV), especially for female L. anatina. These results indicate that the reproductive quality of L. anatina at the Aceh northern shore was maintained due to minimal exploitation from the surrounding community. Furthermore, the biometric (length – weight relationship) of L. anatina in the Aceh northern shore showing an isometric and negative allometric pattern. Basically, allometric growth is temporary, for example due to changes related to gonadal maturity, while isometric growth is a continuous change that is proportional.

Octopus is a biota with very high economic value, so it has become commercial and has high demand. Breuh Island is one of the suppliers of fresh octopus, both within and outside the Aceh region. One step to increase the selling price and long shelf life is to make the octopus into a pickled product. Kube Mangat is the fishery entrepreneur specializing in octopus processing in the Breuh Island area. Kube Mangat produces processed octopus in a very traditional way, both in terms of drying and storing the product. This service utilizes methods derived from research results, including proximate tests and microbiological tests. The results of this research explain that salted octopus products can last in excellent quality until the fourth month. The results of the research were disseminated to Kube Mangat partners and the Gampong Gugob community. This service has also successfully assisted Kube Mangat in obtaining a PIRT number, halal certificate, and trademark registration at the Ministry of Law and Human Rights. Because Kube Mangat has standardized its product packaging, it is currently suitable for entering the modern market.

The Krueng Aceh watershed, vital to Banda Aceh and Aceh Besar, is increasingly threatened by ecological disruption from land-use changes that cause erosion, turbidity, and increased runoff. This study aimed to analyze the quality conditions of the Krueng Aceh River using benthic macroinvertebrates as bioindicators of BMWP-ASPT. The analysis was conducted from March to August 2024 and used a purposive sampling method. Observation stations were distributed at 10 points along the river, representing the upstream, middle, and downstream sections of the river. The upstream and middle sections of the river used surber nets, while the downstream section used PVC pipes to collect benthic macroinvertebrates. The assessment was based on community structure, the Biological Monitoring Working Party-Average Score Per Taxon (BMWP-ASPT) method, and physicochemical parameters of water and substrate. We recorded 29 macroinvertebrate families: 15 are in the original BMWP, and 14 additional families were incorporated to adapt the index. River health showed a clear longitudinal gradient, with upstream good, midstream moderate, and downstream poor, consistent with physicochemical patterns and downstream pressures. It is concluded that BMWP-ASPT is effectively adapted for diagnosing the condition of the Krueng Aceh watershed.
