Abstract

Micro Small to Medium Enterprises (MSMEs) are one of the economic pillars of society in Indonesia. Most people choose MSMEs as their livelihood because of the relatively small capital and fast results. In Krembung Village, many MSMEs have been established in various fields, including culinary, fashion, services, and many more. However, most of the culinary sector still uses conventional marketing. This marketing is considered less effective in this digital era. The method of non KKN T MBKM in this service is by observing MSMEs, creating Instagram accounts and banners, as well as digital marketing training. The result of implementing this service is that culinary MSMEs understand digital marketing and promotions and get an increase in sales after implementing this digitalization.

Abstract

This study aims to optimize the hydrolysis process of gayam fruit peel waste using the acid method to produce glucose, which serves as a raw material for bioethanol production. Gayam peel waste contains a high amount of cellulose, which can be converted into glucose through acid hydrolysis. The process began with a delignification step using an 8% NaOH solution at 80°C for 60 minutes to reduce the lignin content. This was followed by hydrolysis using hydrochloric acid (HCl) with varying concentrations (1, 2, 3, 4, and 5 N) and durations (90, 120, 150, 180, and 210 minutes). Optimization was performed using the Response Surface Methodology (RSM) with Minitab 18 software. The RSM results indicated that the highest glucose yield was achieved at a 5 N HCl concentration and 156.67 minutes of hydrolysis time, with a predicted glucose content of 24.37%. Validation using UV-Vis spectrophotometry and the Nelson-Somogyi method showed an actual glucose content of 4.7217% or 47.217 ppm. These findings demonstrate that gayam fruit peel waste can be efficiently converted into reducing sugars and holds significant potential as an environmentally friendly raw material for bioethanol production.

Abstract

Air laut mengandung beragam ion logam, terutama ion kalsium (Ca2+) dan magnesium (Mg2+) yang menyebabkan masalah di berbagai industri, seperti pembentukan kerak pada peralatan industri dan pengolahan air minum.  Penelitian ini bertujuan untuk menentukan kondisi terbaik dalam penghilangan ion Ca2+ dan Mg2+ menggunakan Na₂CO₃ sebagai agen pengikat kalsium dan magnesium dan penambahan NH4OH sebagai bahan pengikat magnesium pada tahap kedua. Proses penghilangan dilakukan melalui reaksi pengendapan dengan variasi konsentrasi Na₂CO₃ yaitu 0,1, 0,2, 0,3, 0,4, dan 0,5 M, serta suhu operasi 30, 45, 60, 75, dan 90 °C. Waktu pengadukan ditetapkan selama 5 menit, diikuti dengan pengendapan selama 1 jam. Konsentrasi NH4OH ditetapkan pada 6,49 M berdasarkan hasil perhitungan stoikiometri. Kadar ion Ca²⁺ dan Mg²⁺ sebelum dilakukan perlakuan dan sesudah perlakuan dianalisis menggunakan metode titrasi kompleksometri dan atomic absorption spectrometry (AAS). Hasil penelitian menunjukkan bahwa peningkatan konsentrasi Na₂CO₃ dan suhu operasi berbanding lurus dengan persen penyisihan ion Ca²⁺ dan Mg²⁺. Analisis statistik menggunakan ANOVA dua arah juga menunjukkan nilai p < 0,05. Kondisi terbaik didapatkan pada penambahan natrium karbonat pada konsentrasi 0,5 M dan suhu 90 °C, dengan persen penyisihan  ion Ca²⁺ mencapai 97,85% dan ion Mg²⁺ sebesar 96,91%. Hasil penyisihan tersebut belum memenuhi standar SNI, karena kadar ion Ca2+ dan ion Mg2+ didapatkan sebesar 180,351 mg/L dan 182,288 mg/L, sedangkan standar SNI pada air minum kadar Ca2+ sebesar 10 mg/L dan kadar Mg2+ sebesar 150 mg/L. Penelitian ini mendukung pengembangan pra-pengolahan air laut yang lebih efisien dengan menurunkan kadar ion Ca²⁺ dan Mg²⁺ dalam industri air minum.

Abstract

Shell waste accumulates along the coastal areas of Surabaya and Sidoarjo, with various types of shells including blood shells, green shells, feather shells, kampak shells, and batik shells. Currently, the waste from these shells is not being utilized optimally. Marine shell waste contains more than 95% calcium carbonate (CaCO3), making it suitable for the production of aragonite crystals, which can serve as raw materials for applications such as bone regeneration, paper manufacturing, and as fillers in rubber and plastics. The objective of this research is to synthesize aragonite from five types of marine shells and to investigate the effect of carbonation temperature on the percentage of aragonite formation. The method employed for synthesizing aragonite crystals is carbonation. Initially, the CaCO3 derived from marine shells is calcined at 900°C to produce calcium oxide (CaO). This calcium oxide is then dissolved in hydrochloric acid (HCl) to form calcium chloride (CaCl2). Subsequently, sodium hydroxide (NaOH) is added to CaCl2, and carbon dioxide (CO2) gas is bubbled through the solution to precipitate CaCO3 along with by-products of NaCl and water. The variables examined include comparisons among five types of shells (blood shells, green shells, feather shells, kampak shells, and batik shells) at calcination temperatures of 30°C, 60°C, and 90°C. The best results were obtained from the synthesis using green shells, yielding an aragonite crystal polymorph percentage of 76.4% at a carbonation temperature of 90°C. Conversely, the smallest yield of aragonite crystal polymorph was observed with batik shells at 26.0%.

Abstract

The utilization of biowaste as an alternative raw material has attracted increasing attention in biomaterial research. Snail shell waste, which is abundant and underutilized, contains a high calcium carbonate content and offers a unique, low-cost, and sustainable precursor for calcium phosphate synthesis, particularly for bone substitute applications. This study aimed to synthesize calcium phosphate from snail shell waste using the hydrothermal method and to evaluate the effects of pH and hydrothermal time on phase formation, purity, and particle size. The shells were calcined at 800 °C for 4 hours to produce calcium oxide (CaO), then reacted with phosphoric acid at pH 8–12 under hydrothermal conditions for 25–125 minutes. The precipitates were dried and sintered at 1000 °C for 5 hours. X-ray fluorescence analysis showed a CaO content of 99.20%. X-ray diffraction revealed calcium hydrogen phosphate, hydroxyapatite, and calcium carbonate phosphate hydroxide phases. The highest hydroxyapatite content (54%) was obtained at pH 8 and 25 minutes. Higher pH and longer processing time reduced purity. Scanning electron microscopy showed granular morphology, with particle sizes decreasing from 63 nm to 28 nm as pH increased. Although promising, the hydroxyapatite content does not yet meet RSNI3 ISO 13175-3:2012 requirements.

Abstract

This study investigates the synthesis of hydroxyapatite (HA) from mussel shells using the hydrothermal method, focusing on the CaO to (NH₄)H₂PO₄ ratio and reaction temperature as critical parameters. Increasing seafood consumption in the Surabaya region has resulted in greater shell waste, necessitating the exploration of sustainable practices in utilizing this byproduct for bio-materials, particularly in bone implants. The research employs a hydrothermal approach due to its efficacy in controlling HA crystal morphology and enhancing crystallinity. Experimental findings indicate that the optimal yield of 69.64% occurs at a 1.7 Ca/P ratio and 96 °C, validating the importance of both parameters in achieving adequate material characteristics. XRF and XRD analyses confirm the synthesized HA's chemical composition and a high degree of crystallinity at 81.01%, exceeding the minimum requirements for biomedical applications. However, Ca/P ratios slightly above the standard range suggest incomplete reactions during synthesis. This study makes a new contribution by systematically evaluating the combined effects of the Ca/P precursor ratio and moderate hydrothermal temperature on the synthesis of hydroxyapatite derived from local shell waste in general. The results of this study demonstrate the potential of marine shell waste as a sustainable source of calcium for producing hydroxyapatite with high crystallinity suitable for biomaterial applications, thereby supporting the development of environmentally friendly biomaterials for medical use.
