Abstract

Sources of activity in Dorei Bay come from the Sanggeng market, the Wosi market, the port, the PLTD (Diesel Power Plant), hospitals, hotels, and residential areas. The seagrass system has a function as a food provider, as primary productivity in waters, dampers the arrival of waves, a place for growth and development of biota and sediment traps. Research and information on the accumulation of heavy metals in seagrass, especially Cymodocea rotundata are still very limited, especially in Doreri Bay. This study aims to describe the accumulation of heavy metals in seagrass Cymodocea rotundata, including leaves, roots, and rhizome, comparing the accumulation of heavy metals in seagrass Cymodocea rotundata each location as well as knowing the pollution index of each location. The research was conducted in Doreri Bay, Manokwari, West Papua in August 2018. The sampling locations for Cymodocea rotundata seagrass were around the waters of Pelayaran, Wosi, Yankarwar, Anggrem, and Nusmapi Island. The results showed that the highest Cu concentrations were described from each location, which ranged from 18.75 to 28.64 (mg.kg-1), followed by heavy metal Pb ranging from 0.46-19.31 (mg.kg-1), then logm weight of Cd ranged from 1.11-4.97 (mg.kg-1) and the lowest Cr6 + concentration in each location ranged from 0.20 -0.52 (mg.kg-1). The percentage of metal concentrations in the roots and rhizomes is 50%, it can even reach 82.64%, namely Pb metal at Yankarwar Beach. Meanwhile, the metal concentration in the leaf area ranged between 17.36-50.00% and the highest proportion was found in Pb metal at the Pelayaran location and Cr6 + metal at the Wosi location. The calculation results of the Metal poluttion Index (MPI) for heavy metals Pb, Cd, Cu, and Cr6 + show that the highest heavy metal index of 5 locations is on Anggrem Beach and the lowest is at Pelayaran Beach

Abstract

Senggreng Village is one of the areas in Sumber Pucung District, Malang Regency, promising to be developed in agriculture, animal husbandry, fisheries, and agro-tourism. Abundant water resources mainly support the fisheries and agriculture potency due to its position near the Sutami Dam. One of the community groups in Senggreng Village, "Sumber Duren", is "engaged in developing a small amusement park that integrates culinary, fishing park and freshwater fish farming business, managed through a cage system. Regardless of its considerable potency, fish farming has not been carried out intensively, especially due to the high prices of commercial fish feed. Therefore, this community service team proposed a solution by initiating mealworm (Tenebrio molitor) cultivation as a cheap, high-protein, and sustainable source of fish feed to increase crop yields. Experienced mealworm practitioners also provided intensive mealworm cultivation education, training, and profitable business planning. Through this program, the community group "Sumber Duren" has been" successful in cultivating mealworms starting from the seedling phase to becoming broodstock and laying eggs. Based on the questionnaire data collection, most community group members stated that this community service activity helped provide new knowledge interested in cultivating alternative feeds, and 80% of respondents expected the activity to continue in the following years.

Abstract

Edible film merupakan lapisan tipis atau film yang terbuat dari komponen yang dapat dimakan dan berfungsi melapisi produk pangan. Bahan pembuatan edible film adalah dari kelompok karbohidrat, lemak, protein dan bahan pengemulsi serta bahan penstabil. Rumput laut seperti Eucheuma spinosum dan Sargassum filipendula adalah biopolymer yang bersifat biodegradable. Bahan pembentuk film tidak hanya dari kelompok rumput laut akan tetapi Chitosan juga dapat dipadukan dalam pembuatan edible film. Chitosan adalah kationik. Eucheuma spinosum adalah bahan penghasil iota caragenan yang bersifat anionik. Sehingga diharapkan dari campuran bahan yang bersifat kationik dan anionik dapat memperkuat ikatan film. Pada penelitian ini didapatkan hasil kadar air berkisar antara 15,87 ± 0,35% hingga 21,23 ± 0,21%. Nilai ketebalan berkisar antara 0,04 ± 0,01 μm hingga 0,17 ± 0,00 μm. Nilai tensile strength berkisar antara 1,38 ± 0,04 MPa hingga 19,45 ± 0,06 MPa. Nilai elongasi berkisar antara 1,10 ± 0,10% hingga 8,93 ± 0,01%. Nilai transmisi uap air berkisar antara 0,00 ± 0,00 g/m2.jam hingga 0,02 ± 0,00 g/m2.jam.   Edible film is a thin layer or film made of edible components and functions to coat food products. Materials making edible films are from the group of carbohydrates, fats, proteins and emulsifying agents and stabilizers. Seaweeds such as Eucheuma spinosum and Sargassum filipendula are biodegradable biopolymers. Film-forming materials are not only from the seaweed group but also Chitosan. Chitosan is cationic. Eucheuma spinosum is an anionic which iota caragenan producing material. So it is expected that the mixture of cationic and anionic materials can strengthen the film bond. In this study, the results of water content ranged from 15.87 ± 0.35% to 21.23 ± 0.21%. The thickness value ranged from 0.04 ± 0.01 μm to 0.17 ± 0.00 μm. Tensile strength values ranged from 1.38 ± 0.04 MPa to 19.45 ± 0.06 MPa. Elongation values ranged from 1.10 ± 0.10% to 8.93 ± 0.01%. Water vapor transmission values ranged from 0.00 ± 0.00 g/m2.h to 0.02 ± 0.00 g/m2.h.

Abstract

There is increasing awareness of the importance of sustainability in aquaculture, however, research that explicitly integrates accounting with environmental information in decision-making remains relatively unexplored. Sumenep Regency in East Java is one of the largest producers of vannamei shrimp with high economic value. This research was conducted at a vannamei shrimp farming company in the area. This company uses a semi-intensive system and has made efforts to care for the environment, but has not fully integrated environmental aspects into its financial support. It has the potential to hurt sustainability. Environmental management accounting is an accounting approach that integrates environmental information into the company's accounting system, to support better decision-making in terms of environmental and economic performance. This study aims to design a scenario for the sustainability of aquaculture vanname shrimp (Litopenaeus vannamei) business through environmental management accounting in the company Sumenep Regency. The data are collected through interviews, observation, and documentation. It employs prospective analysis of SMIC-Prob based on probability with subjective probability. It is used to compute the probability of the event. This study uses probability sampling. The experts are top manager, middle managers in production and finance, local government, and researchers in fishery agribusiness. This study shows that the primary scenario recommendation for the sustainability of vanname shrimp farming is integrated environmental management in accounting. Meanwhile, the government needs to support them to apply it through socialization, regulation, and educating/training about it.

Abstract

The aim of the study was to find out the effect of using kappa caragenan as an Lactobacillus acidophilus encapsulating material on viability and “shelflife”. The research method was an experimental laboratory design with Completely Randomized Design (CRD), ANOVA, followed by the Fisher test, to test for differences. Data analysis using Minitab 16 software. The research treatment was the concentration of kappa caragenan with sub-treatment as follows: A1 (2%); A2 (2.5%); A3 (3.0%); A4 (3.5%); A5 (4.0%); A6 (4.5%) The results showed that the use of different concentrations of kappa caragenan as an encapsulation material for Lactobacillus acidophilus had a very significant  difference effect on the viability of Lactobacillus acidophilus and encapsulation yield. Viability increases with increasing concentration of kappa caragenan used. The highest viability of 8.71 log CFu / mL was obtained using a 4.5% kappa caragenan concentration with a “Shelflife” calculation of 65.73 years of storage at 5oC. The research suggestion was testing 4.5% Lactobacillus acidophilus microcapsules encapsulated by kappa carrageenan in GI Tract simulation solution. Keywords: Eucheuma cottonii, Microencapsulation, Emulsification
