Bungus Oceanic Fishing Port, located in Padang, West Sumatra, is responsible for overseeing the unloading process of fish catches. This process is carried out by the crew after the vessel docks at the port. Due to the involvement of many workers, the unloading process presents a high risk of occupational accidents. This study aims to identify occupational accident cases among captains and crew …
Coastal ecosystems play a crucial role in supporting biodiversity but are increasingly threatened by heavy metal pollution originating from industrial and domestic activities. The mangrove species A. alba possesses the ability to absorb heavy metals through phytoremediation processes, making it a promising bioindicator of environmental contamination. This study aimed to analyze the concentratio…
Industrial and shipping activities in West Dumai pose a risk of heavy metal contamination in coastal waters, potentially leading to bioaccumulation in organisms such as Geloina erosa and Cerithidea obtusa. This study aimed to determine the accumulation of lead (Pb), copper (Cu), and zinc (Zn) in the soft tissues of both species and to compare the concentrations between species and sampling stat…
Coastal areas have high potential for natural resources, but the intensity of their utilization often leads to physical environmental changes. One of the significant impacts is land subsidence and sea level rise, which trigger tidal flooding (known as rob floods). This study aims to determine the rate of sea level rise based on tidal data analysis from 2015 to 2024, and to predict inundation ar…
Global warming is caused by increasing greenhouse gas emissions, particularly CO₂, and can be controlled through carbon sequestration by vegetation, including mangrove trees. The study was conducted in January-February 2025 in the mangrove area of Penempul Village, Sungai Sembilan District, Dumai City, Riau Province, with the aim of determining density in relation to biomass, carbon stock, an…
Mangroves are forests that grow in coastal areas and play an important role in maintaining environmental balance, because the health of this ecosystem greatly affects the stability of coastal areas and the survival of communities that depend on natural resources. This study aims to analyze the Mangrove Health Index (MHI) in the coastal area of Kutawaru Village, Cilacap Regency, Central Java. Th…

Coral reefs play a crucial role in maintaining marine biodiversity by providing habitat and resources for various types of marine organisms, including reef fish from the Pomacentridae family. This study aims to determine the condition of coral reef cover, the abundance of reef fish from the Pomacentridae family, and the relationship between coral reef cover and the abundance of reef fish from t…
Currently, food technology has transformed the function of food, beyond simply relieving hunger, it is also used to produce functional food products that protect the human body and treat various diseases. One such product being developed is a probiotic drink. This research was carried out from October to December 2024 at the Marine Microbiology Laboratory, Department of Marine Sciences, Faculty…
ABSTRACT The increase in the number of laundry services will be directly proportional to the amount of liquid waste generated at the end of the activity. Therefore, it is necessary to develop effective and environmentally friendly waste treatment methods. The adsorption process is still the best choice for liquid waste treatment, especially if it uses environmentally friendly adsorbents, for e…
ABSTRACT Silica gel is a material widely used in the industrial sector as an adsorbent, filler, and catalyst support. It can be synthesized from various natural sources containing silica (SiO₂), one of which is laboratory glass waste. In this study, silica gel was synthesized from laboratory glass waste through the production of sodium silicate, followed by precipitation using HCl solution. …

This research aimed to analyze the sustainable development strategies for the pineapple chips small and medium industry in Kampar Regency. The study was conducted at the pineapple chips small and medium industry in Kualu Nenas Village, Tambang District, Kampar Regency, Riau Province. The research employed observation with both qualitative descriptive and quantitative descriptive approaches…
ABSTRACT Sago starch is one of the carbohydrate-producing plants extracted from the pith of the stem. The use of natural sago starch as a source of starch in food products is still limited because it has deficiencies in physicochemical characteristics. Modified combination of fermentation and annealing method was carried out on sago starch which has limitations in physicochemical characteristi…
ABSTRACT An evaluation of community-based mangrove rehabilitation activities in Jangkang Village, Bengkalis Regency, was conducted to determine the factors influencing the success of the programme and its effectiveness. Rehabilitation focused on two locations: the coastal area and the Jangkang River. The approach used was descriptive qualitative with in-depth interviews, field observations, li…
ABSTRACT Corn is the third most important food crop after rice and wheat in Indonesia. The decrease in corn production in Riau Province is caused by several factors, one of which is the presence of weeds. The purpose of this study was to determine the interaction of pre-emergence herbicide application timing and weed weeding, the combination of pre-emergence herbicide application tim ing and w…
ABSTRACT Rice plant (Oryza sativa L.) is an important food crop commodity in Indonesia, providing calories and nutrients as a staple food for the Indonesian people. Rice cultivation is inseparable from pest attacks, which have a significant impact on decreasing rice production. One such pest is the brown planthopper (Nilaparvata lugens Stal.), which can cause total crop failure. One plant …
Lokan (Polymesoda expansa) is a bivalve that lives in mangrove forest areas and has important ecological and economic values. The lokan population plays a role in maintaining water quality and is a source of livelihood for coastal communities. This study aims to analyze the abundance, distribution patterns, and frequency distribution of individual sizes of P. expansa in the mangrove forest of B…
Coral reefs are massive piles of sediment produced from calcium carbonate produced by the phylum cnidaria, class anthozoa, order madreporaria, with the addition of calcareous algae and other organisms that produce calcium carbonate. One group of biota that lives in association with coral reefs and plays an important role in the coral reef ecosystem is Chaetodontidae fish. The taking of the Chae…
