ABSTRAKPenelitian dilakukan untuk mengkaji mutu sedimen habitat kerang darah (Anadara granosa L) berdasarkan preferensi reburial. Uji dilakukan terhadap sedimen yang berasal dari Estuari Wakak-Plumbon di Kabupaten Kendal dan sedimen dari Pulau Panjang, Kabupaten Jepara, Jawa Tengah.Hasil pengujian menunjukkan bahwa kerang darah yang dipapar dalam sedimen dari estuari Wakak-Plumbon dan Pulau Panjang tidak menunjukkan kegagalan dalam upaya membenamkan diri (reburial failured) setelah dipapar selama 48 jam. Perbedaan hanya terjadi dalam waktu adaptasi sebelum membenamkan diri. Kerang darah umumnya membutuhkan waktu yang lebih lama untuk adaptasi sebelum membenamkan diri pada sedimen yang berasal dari Estuari Wakak-Plumbon dibanding dari Pulau Panjang.Kata kunci: Habitat, kerang darah, reburialABSTRACTThis research conducted to determine quality of sediment for habitat of blood cockle based on reburial reference. Test done to sediment from Wakak-Plumbon estuary on Kabupaten Kendal and from Panjang Island, Kabupaten Jepara, Central Java. The results showed that blood cockle exposed to sediment from two location are not different in reburial failured, but different in time needed for adaptation before reburial. Anadara granosa needed more time to adapted, before reburial in Wakak-Plumbon sediment.Keywords: habitat, blood cockle, reburial

The purpose of this study was to evaluate Pb, Cr, and Cd levels inside the Anadara granosa and to investigate the effect of submersion using Citrus aurantifolia (lime) and Orthosiphon aristatus (kidney tea leaves) solution on Pb, Cr, and Cd levels contained in the blood cockles taken from 10 markets in the city of Semarang, Central Java, Indonesia (Johar, Genuk, Gayamsari, Jati, Peterongan, Karangayu, Mangkang, Pedurungan, Boom Lama, and Ngaliyan). The concentration of heavy metals of Anadara granosa was analyzed using Atomic Absorption Spectrometer (AAS). Analysis of variance (ANOVA) showed that heavy metals (Pb, Cd, and Cr) of blood cockle taken from 10 markets provided no significant difference (P < 0.05) on the content of Pb, Cd and Cr. Purification was carried out using Citrus aurantifolia (lime) and Orthosiphon aristatus (kidney tea leaves) solution. The lowest Pb (0.00 mg kg–1) was obtained from Boom Lama and Peterongan market with purification using kidney tea leaves solution, while the lowest Cr [(0.30 ± 0.00) mg kg–1]) was obtained from Genuk market with lime solution. In addition, the lowest Cd (0.00 mg kg–1) was obtained from Boom Lama market with purification using kidney tea leaves solution. Accumulation of heavy metal contamination in blood cockle could affect the micronutrient status and consumer health.

Solang M, Lamondo D, Kumaji SS. 2017. Zinc, calcium, protein, lead, mercury, and the sensorics quality of cireng snacks supplemented with blood cockle (Anadara granosa). Nusantara Bioscience 9: 385-391. Blood cockle (Anadara granosa) is a potential nutritious food with high economic value. This study aims at evaluating the level of zinc, calcium, protein, mercury, lead, and the sensorics quality of cireng (traditional Indonesian snack made from fried-tapioca flour dipped into sauces) supplemented with blood cockle. This study used complete randomised design, where the treatment factors consisted of flour made from blood cockles to supplement the flour used in making the cireng snacks. The concentration of the treatment factors were 0%, 5%, 10%, 15%, and 20%. The data were analyzed using the One Way ANOVA test and LSD test. This study shows that blood cockles’ supplementation significantly increases the level of protein (p=0.05), zinc (p=0.031), calcium (p= 0.016), lead (0.000), mercury (p= 0.022) of the cireng snacks. Supplementation of blood cockles has increased the preference toward cireng’s flavor, aroma, and color by 10%, whereas the level of preference toward the texture of cireng which used the blood cockle has increased by 20% compared to cireng product with non-supplemented flour. The level of lead (Pb), and Mercury (Hg) are below the Indonesian National Standard (SNI). Supplementation of blood cockles from Gorontalo in the flour used in making the cireng snacks produced snacks with a better nutrition value and safe to consume. Also, the flavor, color, texture, and aroma are acceptable.

A survey research on the blood cocle (Anadara granosa) business was conducted in Rokan Hilir Regency, Riau Province, Indonesia in June-July 2020. The research objective was to formulate a strategy to develop the blood cockle business, in order to increase the income of fishermen’s families. Interviews were conducted with 10 respondents of blood cocle cultivators, local government, fisheries office, traders and blood cockle exporters. Data were analyzed using the SWOT analysis method (Strengths, Weaknesses, Opportunities, and Thereats). The results showed that the land used for the cultivation of blood cockle in Rokan Hilir was only 10% of the 12,434 hectare. The number of blood cockle cultivators in this area is only 250 people, the export volume of blood cockle is 450 tons per month (IDR 5.5 billion). The future strategy for developing a blood cockle business is: (1) increasing the productivity of blood cocle by increasing business capital, expanding cultivation land, and receiving government assistance; (2) improve the quality of blood cockles, both in terms of size and freshness when marketed; and (3) self-seeding blood cockle.

Entrepreneurship of principals in the educational environment to enhance students' creative behavior and achievements through innovation and the development of learning methods is very important. The principal has the task of managing resources and taking advantage of opportunities in improving the quality of education. This study aims to discuss the significant variables in increasing entrepreneurship principals. The study uses a quantitative approach with path analysis. The research sample was 334 Principals of Kindergarten, Elementary, Middle and High Schools in Central Java Province. Data collection was carried out by studying documentation and questionnaires. Data analysis was performed by path analysis with the AMOS program. The results showed that the rank and tenure as a teacher had a positive and significant effect on the tenure as a principal. While the use of social media has a significant negative effect. Of the various independent variables observed, only the existence of opportunities that had a significant positive effect on the ability of innovation of the principal. While the variables that significantly influence the development of learning methods are the ability of innovation and the presence of opportunities. The development of learning methods and the existence of opportunities will subsequently have a positive effect on improving student achievement, as the ultimate goal of developing entrepreneurship by the principal. Pathways to improve the entrepreneurship of principals are the existence of opportunities, tenure as principal, innovation and the development of instructional media.
