KARAKTERISTIK SABUN CAIR EKSTRAK BUAH LERAK DENGAN VARIASI KOLAGEN IKAN KOMERSIAL

Liquid soap is widely favored for its practicality and ease of use, making it a popular personal care product. Fish collagen is well-known for its ability to improve skin hydration and texture, while soapnut fruit (lerak) serves as a natural cleansing agent due to its high saponin content. This study evaluated liquid soap formulations containing different concentrations of commercial fish collagen (1%, 3%, and 5%) using a completely randomized design (CRD). The parameters assessed included viscosity, pH, total plate count (TPC), and organoleptic properties (color, aroma, and consistency). The results indicated that increasing collagen concentrations led to a significant rise in viscosity, with the 1% collagen formulation (treatment A) achieving an optimal viscosity of 1650 mPa·s, which complies with liquid soap standards. All formulations maintained pH levels within the acceptable range of 8–11 and met microbiological safety standards based on TPC analysis. Organoleptically, treatment A was rated the highest, featuring a visually appealing light grey color, a pleasant virgin coconut oil aroma, and a suitable consistency. Overall, the 1% collagen formulation (treatment A) was identified as the optimal formula, meeting the requirements of the Indonesian National Standard for liquid soap (SNI 06-4085-1996)

ANALYSIS OF POLLUTION LOAD IN THE WELANG RIVER DOWNSTREAM BASED ON ORGANIC AND HEAVY METAL PARAMETERS

To assess water pollution in the downstream of the Welang River, this research examines several key water quality indicators, including organic indicators (DO, COD, TSS) and selected toxic substances such as ammonia, chromium, and sulfide. Water samples were collected from four monitoring stations representing the estuarine zone and analyzed using the Pollution Index method in accordance with Government Regulation No. 22 of 2021. The results showed that DO levels varied between 3,6-4,2 mg/L, with COD levels reaching up to 25 mg/L, respectively. The highest level of TSS concentration was recorded at Station 4 (200 mg/L), while the highest ammonia level at Station 2 (1,38 mg/L). Chromium and sulfide levels varied between 0,015–0,031 mg/L and 0,0016–0,0029 mg/L. By integrating both organic and toxic parameters within a unified assessment framework, this approach offers a more detailed characterization of estuarine pollution—an area often underrepresented in national water quality monitoring programs. The analysis indicates that all stations are moderately to heavily polluted. These conditions are likely caused by a combination of domestic waste, agricultural runoff, and effluents from nearby industrial activities. These insights are intended to support better environmental planning and pollution control strategies, especially in coastal and estuarine zones under growing human pressure

ENVIRONMENTAL FRIENDLINESS EVALUATION OF GILLNET FISHING GEAR IN MUARA KINTAP VILLAGE, KINTAP SUB-DISTRICT, TANAH LAUT REGENCY

Gillnets are widely used fishing gears whose environmental impact varies based on their design and application. This study focuses on assessing the environmental friendliness of two types of gillnets—drift gillnets and encircling gillnets—used by artisanal fishermen in Muara Kintap Village, Kintap Subdistrict, Tanah Laut Regency. The research employed a census (total sampling) approach involving 16 respondents from the KUB Putra Pantai fishermen group. Primary data were collected through interviews, observations, and documentation. The environmental friendliness of the fishing gears was assessed using nine criteria derived from the Code of Conduct for Responsible Fisheries (CCRF) by FAO (1995), which include gear selectivity, impact on habitat and biodiversity, catch quality, fisher and consumer safety, by-catch level, involvement of protected species, and social acceptance. Drift gillnets obtained a total score of 28.3, while encircling gillnets scored 26.8. Both are categorized as environmentally friendly fishing gears. The findings show that neither gear type causes habitat damage; both yield good-quality fish, are safe for users and consumers, and are socially accepted. However, both exhibit low selectivity, with Sardinella fimbriata dominating the catch (78.97% for drift gillnets and 88.24% for encircling gillnets). Both drift and encircling gillnets are considered environmentally friendly according to CCRF criteria. Nonetheless, the low selectivity level highlights the need for improvements in gear design and fishing practices to enhance sustainable fisheries management

PENGARUH PENAMBAHAN EKSTRAK JAHE MERAH (ZINGIBER OFFICINALE ROSCOE) TERHADAP KARAKTERISTIK BAKSO IKAN PATIN (Pangasius, sp)

This study aims to investigate the effect of adding red ginger extract (Zingiber officinale Roscoe) on the chemical characteristics (moisture content and protein level) and organoleptic properties (color, aroma, taste, and texture) of catfish (Pangasius sp.) meatballs. The study used a Completely Randomized Design (CRD) with six treatment concentrations of red ginger extract: 0%, 12%, and 18%, each with three replications. The results showed an increase in moisture content from 55.10% to 61.19% and protein content from 10.50% to 12.99% as the concentration of red ginger increased. Organoleptic testing indicated the highest hedonic scores were observed at the 6% treatment level across all sensory parameters

EFFECTIVENESS OF WATER HYACINTH (EICHHORNIA CRASSIPES (MART.) SOLMS.) DAN KIAMBANG (SALVINIA MOLESTA D. S. MITCHELL) IN PHYTOREMEDIATION OF MANGANESE (MN) HEAVY METAL LEVELS IN DUG WELL WATER IN SUNGAI ULIN HOUSING ESTATE, NORTH BANJARBARU DISTRICT, SOUTH

Dug wells are water that comes from the ground and are still widely used by Indonesians, especially in the Banjarabaru area of Sungai Ulin Housing in South Kalimantan Province. The heavy metal problem that is often encountered is manganese content. Manganese is a heavy metal that is often found in the earth's skin and is often found together with iron. Manganese heavy metal levels that exceed quality standards can make well water yellowish in color, smell of rust due to its high content and if left for several days there will be sediment in the bucket, causing a yellowish color on white clothes and can cause health problems. Improving water quality is very important, one of which is the phytoremediation method. Phytoremediation is a method of utilizing plants to remove harmful organic and inorganic substances. In this study, the authors used water hyacinth and kiambang because of their ability to absorb heavy metals in water. The purpose of this study was to determine the effectiveness of heavy metal manganese absorption using water hyacinth and kiambang plants in dug well water in Sungai Ulin Housing. The research was conducted using an experimental method using a Completely Randomized Design (CRD) with three repetitions, namely on the 3rd, 6th, and 9th days and three treatments, namely control (without the addition of water plants), water hyacinth plants and Kiambang which were carried out for 3 weeks of research. The measurement results obtained were water hyacinth plants were able to reduce manganese heavy metal levels to 0.016 mg/l with a biomass of 300 grams / 10 liters on day 9 and Kiambang water plants were able to reduce manganese heavy metal levels to 0.017 mg/l with a biomass of 500 grams / 10 liters on day 9

KARAKTERISTIK PROKSIMAT DAN MINERAL TEPUNG KEPALA UDANG WINDU (Penaeus monodon) DENGAN PERENDAMAN FAAS (Filtrat air abu sekam)

Tiger shrimp heads represent a by-product of the processing industry that is not currently utilized. The substantial volume of tiger shrimp production gives rise to a considerable number of by-products, which pose environmental concerns if not properly managed, particularly with regard to the release of odors and the degradation of environmental aesthetics. One potential solution to address these issues is the utilization of tiger shrimp heads as a component of flour production. Shrimp head flour, a preserved product in dry form, is typically ground into flour. Tiger shrimp heads contain chitin, with levels ranging from 15% to 20%. This high level of chitin poses challenges during processing, particularly in the production of flour for use as a raw material in feed. The objective of this study is to ascertain the proximate and mineral composition of tiger shrimp head flour through the use of different concentrations of FAAS (husk ash water filtrate). This study used RAL with three replications and three treatments namely G1 (10% FAAS), G2 (20% FAAS) and G3 (30% FAAS) and G0 (no soaking) as control with 24 hours soaking time. Parameters observed included proximate and mineral. The results showed that shrimp head flour with FAAS soaking produced proximate and mineral characteristics that varied in each treatment, where the yield was (18.2%-22.8), water (5.24%-8.30%), ash (24.44%-25.35%), fat (3.75%-6.43%), protein (44.90%-50.49%), carbohydrate (11.54%-21.85%0), crude fiber (9.77%-13.67%), calcium (2.07%-2.93%), phosphorus (1.15%-1.54%) magnesium (0.31%-0.21)
