PHYSICOCHEMICAL CHARACTERIZATION OF PEDADA FRUIT (Sonneratia caseolaris) SLICE JAM WITH THE ADDITION OF CARAGEENAN
Full text linkThis study aims to evaluate the effect of carrageenan addition on the physicochemical properties of fruit slice jam made from Sonneratia caseolaris. This mangrove fruit contains 0.32% pectin, making it a potential raw material for jam production. However, conventional jam has limitations in practicality, leading to the development of fruit slice jam, which has a compact, non-sticky, and plastic-like texture. The study employed a Completely Randomized Design (CRD) with four treatments: P0 (control, 2% pectin), P1 (1.25% carrageenan), P2 (1.50% carrageenan), and P3 (1.75% carrageenan), each replicated five times. The physical parameters analyzed included hardness, cohesiveness, adhesiveness, and springiness, while the chemical parameters consisted of moisture content, ash content, reducing sugar, and pH. Data were analyzed using one-way ANOVA at a 95% confidence level, followed by Duncan's Multiple Range Test (DMRT). The results indicated that increasing carrageenan concentration significantly (P<0.05) decreased adhesiveness, springiness, and moisture content, while hardness, cohesiveness, ash content, reducing sugar, and pH increased. Thus, carrageenan addition significantly influences the physicochemical properties of fruit slice jam made from S. caseolaris, offering a promising innovation for fruit-based jam productsPenelitian ini bertujuan untuk menganalisis pengaruh penambahan karagenan terhadap karakteristik fisikokimia selai lembaran buah pedada (Sonneratia caseolaris). Buah pedada memiliki kandungan pektin sebesar 0,32%, sehingga berpotensi digunakan dalam pembuatan selai. Namun, selai konvensional memiliki keterbatasan dalam aspek kepraktisan, sehingga diperlukan inovasi dalam bentuk selai lembaran dengan tekstur yang lebih kompak, tidak lengket, dan plastis. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan empat perlakuan, yaitu P0 (kontrol, pektin 2%), P1 (karagenan 1,25%), P2 (karagenan 1,50%), dan P3 (karagenan 1,75%), dengan lima kali ulangan. Parameter fisik yang dianalisis meliputi hardness, cohesiveness, adhesiveness, dan springiness, sedangkan parameter kimia mencakup kadar air, kadar abu, gula reduksi, dan pH. Data dianalisis menggunakan uji One-Way ANOVA dengan taraf kepercayaan 95% dan dilanjutkan dengan uji Duncan Multiple Range Test (DMRT). Hasil penelitian menunjukkan bahwa peningkatan konsentrasi karagenan secara signifikan (P<0,05) menurunkan nilai adhesiveness, springiness, dan kadar air, sementara nilai hardness, cohesiveness, kadar abu, gula reduksi, dan pH mengalami peningkatan. Dengan demikian, penambahan karagenan berpengaruh nyata terhadap karakteristik fisikokimia selai lembaran buah pedada, sehingga dapat menjadi alternatif inovasi dalam pengembangan produk selai berbasis buah pedad

BENTUK DAN KELIMPAHAN MIKROPLASTIK DI PERAIRAN PULAU PASARAN, BANDAR LAMPUNG
No full textMicroplastics are plastic particles formed from plastic degradation to a size of <5 mm. Microplastics in waters can have adverse effects on marine organisms, aquatic ecosystems, and humans. This study aims to determine the shape, size, color, abundance, and distribution of microplastics and to determine the relationship between water quality and the abundance of microplastics in the waters of Pasaran Island. The study was conducted in November-December 2022 in the waters of Pasaran Island. Preparation and identification of microplastics in water samples were carried out in the following stages: sample preparation, organic material degradation, density separation, sample sorting, and observation of microplastic types. Data analysis was carried out using the principle component analysis (PCA) method using the Statistical Program for Social Science (SPSS) version 24 with physical and chemical parameters of the waters. Based on the study, 4 forms of microplastics were obtained, namely fiber, fragments, films, and pellets. The form of microplastic that dominated the four stations was the fiber form at 45.1%. The highest abundance of microplastics was at Station 2 (mangrove ecosystem) at 22.63 particles/liter. PCA analysis showed that the abundance of microplastics in the form of fibers, fragments, films, and pellets was negatively related to pH, salinity, current, temperature, and brightness. Increasing public awareness in reducing the use of single-use plastics and managing plastic waste needs to be done to reduce the abundance of microplastics in the waters of Pasaran Island.Mikroplastik merupakan plastik yang mengalami degradasi hingga menghasilkan partikel dengan ukuran < 5 mm.
