Mangrove diketahui mempunyai komponen fitokimia yang mempunyai kemampuan bioaktif. Uji kualitatif komponen fitokimia diperlukan untuk screening awal eksplorasi komponen bioaktif tanaman. Air adalah pelarut komponen fitokimia yang relatif aman dan tidak polutif. Penelitian ini dilakukan untuk membandingkan komponen fitokimia yang terdapat pada buah mangrove sebelum dan sesudah diekstraksi menggunakan pelarut air. Jenis buah mangrove yang digunakan adalah Rhizophora mucronata, Rhizophora apiculata, dan Avicennia marina. Pembuatan ekstrak buah mangrove dilakukan dengan menggunakan pelarut akuades, dengan proses pecacahan, pembilasan dengan asam sitrat 0,5%, perendaman akuades, pengeringan, sonikasi, dan penyaringan filtrat. Hasil uji fitokimia (kualitatif) menunjukkan kandungan fitokimia yang terdapat pada ekstrak buah Rhizophora mucronata adalah saponin dan steroid, sedangkan kandungan yang terdapat pada ekstrak buah Rizophora apiculata dan Avicennia marina adalah tanin, saponin, dan steroid. Kesimpulan dari penelitian ini adalah pelarut akuades dan pembilasan dengan asam sitrat 0,5% dapat melarutkan komponen fitokimia tanin, saponin dan steroid dalam buah mangrove.
The focus of this research is the effect of intensive and traditional ponds on the organoleptic quality of white shrimp (Penaeus vannamei) during 8 days of storage. The study was conducted in a traditional pond at Manjalling Village, Ujung Loe Sub-District, and intensive ponds at Mariorennu Village, Gantarang Sub-District, Bulukumba District. The study design was carried out using the Randomized Block Design experimental method, with storage treatment of 0,2,4,6,8 days. The parameters studied were appearance, odor and texture. White shrimp from intensive ponds and traditional ponds are put in a cooler with a ratio of 2:1 ice and shrimp. The addition of ice is done every day and organoleptic testing is done at 2-day intervals. Around 10-20 g samples were used for organoleptic test using methods employed in SNI 01-2728.1-2006. Data analyzed using Kruskal Wallis continued with multiple comparisons. Organoleptic test of intensive and traditional ponds in 8 days storage shows the value of organoleptic quality decreases and is not acceptable for consumption, with shrimp appearance values 6.28 and 6.64; the odor of 6.15 and 6.59 and textures of 6.24 and 6.6. The standard organoleptic value is 7 based on SNI method. Therefore, shrimp is rejected because it does not meet the minimum specified quality. The conclusion is the organoleptic quality value of traditional shrimp ponds is higher than intensive shrimp ponds.
The aim of this research was to study the effect of intensive and traditional farming on the chemical composition of whiteleg shrimp (Penaeusvannamei) during storage till up to 8 days. The study on intensive and traditional farming were done at MariorennuVillage, Gantarang Subdistrict and at Manjalling Village, Ujung Loe Subdistrict, respectively, Bulukumba Regency, as well as at the Research and Development Center of Fishery Products of Makassar, South Sulawesi, the Province of South Sulawesi. The research design was conducted by a randomized complete block design with a storage treatment of 0, 2, 4, 6, and 8 days. The parameters studied are water content, ash, lipid, and protein content, as well as total volatile base (TVB), trimethylamine (TMA), pH, and free fatty acids (FFA). Whiteleg shrimps from intensive farming and traditional farming were stored in a coolbox containing with 2: 1 ratio of ice and shrimp, respectively. The addition of ice was carried out every day for 8 days storage, and chemical analysis was condcuted at intervals of 2 days. Chemical testings was carried out based on the SNI method. Samples were measured as much as 10-15g and then chemically tested reffer to the method in SNI. The results for both intensive and traditional farming of whiteleg shrimp showed that storage time had a significant influence on the following parameters i.e. TVB, pH, FFA, water content, and protein content. No significant effect was found for following parameters, namely TMA, ash and fat content.
Mangrove diketahui mempunyai kemampuan bioaktif untuk menghambat aktivitas enzim tirosinase. Penelitian bertujuan untuk menentukan konsentrasi ekstrak buah mangrove yang berperan dalam menghambat melanosis udang vaname selama penyimpanan 10 hari pada 0oC. Buah mangrove yang digunakan adalah Rhizophora mucronata, Rhizophora apiculata dan Avicennia marina. Buah mangrove diekstraksi menggunakan air. Konsentrasi ekstrak yang digunakan adalah 25% dan 50%. Udang disimpan selama 10 hari pada suhu 0oC menggunakan coldbox. Rancangan penelitian menggunakan Rancangan Acak Lengkap Faktorial (RALF). Parameter uji melanosis, organoleptik, warna dianalisis dengan ANOVA, dengan uji lanjut duncan. Parameter organoleptik dianalisis dengan uji non parametrik kruskal wallis, uji lanjut multiple comparison. Hasil penelitian menunjukkan udang yang direndam menggunakan ekstrak mangrove R. mucronata 50% dan R. apiculata 50% kemudian disimpan pada suhu 0oC mempunyai nilai melanosis terendah dibandingkan dengan ekstrak mangrove lainnya. Kenampakan organoleptik udang dapat dipertahankan dengan perendaman ekstrak R. mucronata 50% dan R. apiculata 50%, seluruh ekstrak tidak mempengaruhi bau khas dan tekstur udang vaname. Uji warna menunjukkan R. mucronata 25% mempunyai nilai L* tertinggi yang tidak berbeda nyata dengan R mucronata 50%. Nilai L* udang yang direndam A. marina 25% memiliki tingkat keefektifan terendah dalam mempertahankan nilai L*, seluruh jenis ekstrak, tidak mempengaruhi nilai a* dan b* warna udang. Ekstrak buah mangrove R. mucronata 50% dan R.apiculata efektif dalam menghambat melanosis udang.
This research aims to know the increase of cleaner production environment in the fish processing industry through work motivation and leadership of women fishermen in the Tangerang Regency. A survey method is employed using a path analysis technique, whereas the sampling technique used is proportional random sampling. Samples are obtained from primary data. The results show that: work motivation has a partial significant influence on the increase of cleaner production environment in the fish processing industry; which indicates an increase in work motivation will lead to an increase in the cleaner production environment in the fish processing industry. Secondly, the leadership of women fishermen has a partial significant influence on the increase in the cleaner production environment in the fish processing industry. Third of all, both work motivation and leadership of women fishermen simultaneously have a significant effect on increasing the cleaner production environment in the fish processing industry, indicating a variable increase in the cleaner production environment in the fish processing industry which 55,8% can be accounted for by work motivation and leadership. The path analysis coefficient shows that work motivation has a significant effect on the increase in the cleaner production environment in the fish processing industry, whether directly or indirectly.
