The nutrients was named as MSSIP which were consist of following compositions: urea fertilizer, Arschat-M nutrient, Fe:Co:Ni metal ions (6 : 3 : 9 : 6 : 3). Methods used were identification and analysis of sea phytoplankton. Determination of optimum growth condition, pure culture, and mass culture were using local raw materials-based engineered nutrients or MSSIP (M. Sjahrul-Syahruddin Kasim-Indah Raya-Paulina Taba). Determination of product density of sea phytoplankton biomass, analyses of carbohydrate content, and lipid biomass were done by using haemocytometer and microscope, Luff Schrol method, and soxhlet method (n-hexane as solvent), respectively. Morphology of phytoplankton was identified by using a digital camera microscope, SZ60/sZ60-61. Furthermore, to understand the effect of metal ions, Fe, Co, and Ni added into MSSIP nutrient, identification of nutrient before and after culturing process were done using XRF-Thermo-Fisher. The results showed that Chlorella vulgaris, Dunaliella salina, and Spirulina sp. were suitable as raw materials to produce biofuel. Those three phytoplankton contained 0,3095 g/L, 0,3782 g/L, and 0,3325 g/L biomass, 32,49%w/w, 31,58%w/w, and 29,81%w/w carbohydrates; and 25,95%w/w, 26,82%w/w and 24,53%w/w lipid, respectively.

The kinetics of aluminium(III) and chromium(III) adsorption in an adsorbent prepared by immobilization of Chaetoceros calcitrans biomass on silica ge has been investigated. The functional groups which were probable involved in the adsorption processes also identified. Experimentally, the adsorption was conducted by coloumn and batch method. In this work atomic adsorption spectrophotometric techniques was applied indirectly to determine of the metal ion adsorpted, and infra red spectroscopic technique was used for the identification of functional groups present in the adsorbent. The study included two parts of experiment, i.e. 1) the determination of rate of adsorption and 2) the determination of capacity and energy of adsorption. Results showed that the AI(III) and Cr(III) adsorption data fit quiet well with non linear kinetics model proposed by Langmuir-Hinshelwood giving a first order rate constant, (k1) of 8.65.10-3 min-1 for AI(III) and 9.92.10-4 min' for Cr(III) when the immobilized biomass used as the adsorbent in agreement with the activation energy calculation giving values of 1.184 kcal/mole for Al(111) and 1.877 kcal/mole for Cr (Ill). It was concluded that the adsorption of Al(III) and Cr(III) on Chaetoceros calcitrans immobilized and free Chaetoceros calcitrans adsorbents, may be classified as chemical adsorption, involving entalphi of adsorption in the range of 6-17 kcal/mole. And the infra red spectroscopic data indicated that the functional groups i.e.: carboxylate (-COO), hydroxyl (-OH) silanol (SI-OH), siloksil (SI-O-Si) and amine (NH2) are present in free Chaetoceros calcitrans biomass and silanol (Si-OH), siloksil (Si-O-Si), hydroxyl (-OH)and C-H metilene (-CH2) are present in immobilized biomass Chatoceros calcitrans, while only siloksil (Si-O-Si) and silanol (Si-OH) in silica gel.

This study aims to determine the characteristics of hydroxyapatite/SiO2/gelatin composites to fulfil the bone scaffold standards. XRF analysis showed that limestone has a high CaO content of 92.89%, allowing it be used for hydroxyapatite synthesis. The wet precipitation method was used to synthesize hydroxyapatite; meanwhile, the freeze-drying method was used to synthesize the hydroxyapatite/SiO2/gelatin scaffold. FTIR analysis confirmed the characteristic peaks, which indicated the presence of compounds of hydroxyapatite (OH- and PO43-), SiO2 (Si-OH and Si-O-Si), and gelatin (N-H, C-H, and C=O). XRD analysis showed 98.1% hydroxyapatite phase and 1.9% SiO2 phase and SEM analysis showed a scaffold pore size of 155-218?m, optimal for cell attachment. Furthermore, mechanical testing resulted in a compressive strength of 1.71 MPa and porosity testing resulted in a porosity of 75%. This characterization showed the potential use of hydroxyapatite/SiO2/gelatin composites as bone scaffolds. This research can enable further development of scaffold materials in the field of tissue engineering.

Abstract Crab shell waste, which accounts for 40-60% of the total weight of crabs, is often dumped into the environment, causing pollution in coastal areas. This community service activity aims to provide education and training to the "Mappedeceng" fishing group in Lasitae Village, Tanete Rilau District, Barru Regency, on the utilization of crab shell waste into chitosan as a natural preservative. The implementation method consists of three stages: preparation, implementation (counseling, processing technology training, and direct practice), and evaluation through a pre-post test. The activity was carried out on August 9, 2025, involving 40 participants. The evaluation results showed an increase in participant knowledge of 38.75% based on a comparison of pre-test scores (average 10.575) and post-test (average 18.325). The practical activity of making natural preservatives showed high enthusiasm from the participants, with the majority feeling confident in applying this technology at home. The resulting chitosan has been proven to extend the shelf life of fishery products by two to three times and has a high economic value of around IDR 75,000-100,000 per kilogram. This program has successfully raised awareness among fishermen about the importance of a circular economy in fisheries and provided a sustainable solution to address the problem of crab shell waste while creating new economic opportunities for coastal communities. Keywords: crab shell waste; chitosan; natural preservative; fishermen empowerment; waste processing technology.
