Abstract

ABSTRACTPENDAHULUANPinctada maxima adalah spesiesakuakultur yang mempunyai nilaiekonomi tinggi (Taylor et al. 1997). Dipasaran internasional, mutiara yangdiproduksi sering kali disebut dengannama “South Sea Pearl”. Indonesiatermasuk salah satu negara penghasilmutiara (South Sea Pearl) yang cukupdiskenal di pasaran dunia, sebagian besarproduksi South Sea Pearl yang dipasarkanberasal dari hasil budidaya (Anna2006). Produksi mutiara berbasisbudidaya merupakan aktivitas usaha yangmenguntungkan. Perkembangan usahabudidaya mutiara saat ini sudah mengarahpada kegiatan industri yang terintegrasi(Fassler 1995).The Effect of Temperature and Salinity to The Physiological Respons on The Larvae ofPinctada maxima (Jameson). Energy budget is one of the most sensitive tools available forindividual assessing environmental changes like temperature and salinity, and also prerequisitefor individual growth and survival. The aim of this study is to obtained information on energybudget on routine metabolism, in different levels of temperature and salinity, and to know thelevels of optimum temperature and salinity. The research was used randomized block design,with three replications. The result showed that optimal temperature and salinity on P. maximalarvae was 28 oC and 32 – 34 ‰ (BE and BF). Energy budget to routine metabolism increasedwas attributed to increased temperature and salinity due to the optimal, than would be decreasedwhen temperature and salinity increased. The highest of energy budged for routine metabolismat treatment BF.

ABSTRACTThe Effect of Depth to Deposition Process on Round Nucleus of Fresh Water Mussel (Anodontawoodiana). One of the affecting factors to the quality of pearl culture is the thickness of pearldepositions (nacre). The objective of this study was to obtain information on best level ofdepth to culture of pearl, to get fast nacre deposition and high quality of pearl. The researchwas conducted for 9 months, in the freshwater pond, was 300 m2 wide and 1 m deep. Freshwaterpearl Anodonta woodiana, sized ranging from 12 – 15 cm were studied. Completely randomizeddesign was used with levels of deep treatment (A) 30 cm; (B) 60 cm and (C) 90 cm. The resultshowed that best thickness of pearl deposition by 90 cm deep (1.30 mm) but hasn’t biggestsignificant (P>0.05) to the deep of 60 cm (1.10 mm) and biggest significant (P< 0.05) to the deepof 30 cm (0.70 mm). The result of implantation was followed that 30, 60 and 90 cm deep were 11.9%; 12.2 %; 12.0 %, whereas survival rate was followed 79.2 %; 79 % and 78.7 %.Keywords: Freshwater mussel; Anodonta woodiana; effect; level of deepKata kunci: Kerang air tawar, Anodonta, woodiana, kedalaman laut

Abstract

Penurunan kualitas perairan pada tambak Silvofishery disebabkan kepadatan biota budidaya yang terlalu tinggi dan adanya kelebiha pemberian pakan. Upaya penanggulangan permasalahan untuk meminimalisir kondisi tersebut dilakukan usaha  teknologi biofilter menggunakan rumput Gracilaria sp (Rhodophyta). Untuk dapat mengoptimalkan teknis monitoring pada setiap tahapan budidaya, maka dibandingkan dengan skala laboratoris. Perlakuan penelitian skala laboratorium (A), sedangkan perlakuan di skala lapang (Perlakuan B) dilakukan di tambak Silvofishery, dengan ketentuan umur serta ukuran biota budidaya yang sama. Gracilaria sp yang ditanam dengan metode lepas dasar (bottom method). Monitoring dilakukan selama masa pemeliharaan 60 hari,  dilakukan pengamatan terhadap pertumbuhan rumput laut (biomassa basah).  Analisis data pertumbuhan menggunakan uji T-student. Hasil pertumbuhan Gracilaria sp, rata-rata per 15 hari menunjukkan bahwa pertambahan berat berbeda nyata antar perlakuan (P £ 0,05), yang dipengaruhi oleh respon proses fotosintesis dan penyerapan kandungan Nitrogen (ammonia, nitrat dan nitrit). Pertumbuhan Gracilaria sp lebih tinggi dalam skala laboratoris mencapai 28 gram dibandingkan di lapang pada area tambak silvofishery 24,78 gram.

Abstract

ABSTRACT The objective of the research was to evaluate nutritional values of microencapsulated diet made from single cell protein of microalgae. Complete randomized design was applied using three different types of microalgae for inclusion trials i.e. (A) Nannochloropsis sp., (B) Chlorella sp., and (C) Spirulina sp. with five replications respectively. Microencapsulated diet was produced by a modification method based on thermal cross-linking with stable temperature. Phytoplankton was cultured in sea water for which fertilized by a modification of Walne and Guillard fertilizer. The results showed that the highest value of nutrition content was Spirulina sp. and the average composition of protein, crude lipid, carbohydrate, ash, nitrogen free extract, and water content was 34.80%, 0.30%, 18.53%, 20.09%, 26.29%, and 13.32%, respectively. Organoleptically, microcapsule showed that the color of capsule was dark green and smell fresh phytoplankton. Keywords: microcapsule, single-cell protein, thermal cross-linking, microalgae, phytoplankton  ABSTRAK Tujuan penelitian adalah mengevaluasi kandungan nutrisi pakan mikrokapsul protein sel tunggal (single cell protein) yang berasal dari berbagai jenis mikroalga (fitoplankton).

Abstract

The Mojo Village mangrove forest in Pemalang has undergone environmental degradation due to land conversion into shrimp farming areas. This conversion has led to increased anthropogenic activities, which are potential sources of heavy metal contamination in the waters, particularly lead (Pb). This study aimed to analyse Pb concentrations in sediments and gastropods and assess the potential of gastropods as bioindicators of Pb pollution. Sample preparation followed the USEPA 3051 method, and Pb analysis was conducted using Atomic Absorption Spectrophotometry (AAS). The results identified five gastropod species: Littoraria melanostoma, Littoraria scabra, Cerithidea cingulata, Cerithidea obtusa, and Cerithidea decollata. Pb concentrations in sediments averaged 11.86 ± 1.24 mg/kg, while in gastropods, the average was 0.43 ± 0.16 mg/kg. Although Pb levels in sediments indicate low contamination and no pollution, they may still pose potential biological risks. Cerithidea cingulata and Cerithidea obtusa were categorized as deco-concentrators with the potential to serve as bioindicators of Pb pollution. The study also revealed a very strong correlation between Pb concentrations in sediments and gastropods.

Abstract

Kelompok Wanita Tani (KWT) Kembangturi, Desa Tunjungan, Kecamatan Ngombol, Kabupaten Purworejo, merupakan komunitas masyarakat yang bergerak dalam bidang pertanian dan perikanan. Salah satu usaha yang pernah dijalankan adalah budidaya ikan dalam ember (budikdamber), namun aktivitas tersebut mengalami stagnasi sehingga sarana budikdamber tidak lagi berfungsi. Oleh karena itu, kegiatan pengabdian kepada masyarakat ini dilaksanakan untuk mengaktifkan kembali usaha budikdamber melalui peningkatan kompetensi anggota KWT. Kegiatan yang dilakukan meliputi (1) sosialisasi teknik budikdamber yang disertai pre-test dan post-test, serta (2) simulasi praktik budikdamber. Sosialisasi diikuti oleh 20 anggota KWT. Hasil evaluasi menunjukkan adanya peningkatan pemahaman, dengan nilai rata-rata pre-test sebesar 71,67 dan post-test sebesar 84,28. Selain itu, dilakukan penyuluhan dan pelatihan pembuatan sosis ikan sebagai upaya meningkatkan keterampilan pengolahan hasil perikanan, sekaligus membuka peluang usaha baru yang bernilai ekonomis tinggi dan berpotensi memperluas pasar produk lokal. Seluruh peserta mengikuti kegiatan dengan antusias dan memberikan umpan balik positif terkait pentingnya kegiatan ini dalam mendukung pemberdayaan ekonomi kelompok.
