Petunjuk teknis ini diharapkan dapat memberikan alternatif baru dalam pengasapan ikan menggunakan asap cair, terutama di daerah yang banyak menghasilkan limbah kayu, tempurung kelapa, dan cangkang sawit. Dengan demikian, diharapkan dapat mengurangi buangan hasil panen dan dapat menjadi sumber pendapatan baru bagi masyaraka

One of the crucial aspects related to the production of fish is post-harvest fish loss which will substantially reduce the fish supply. Due to the perishable characteristics of fish, especially in tropical climate areas as Indonesia with high daily temperature and humidity, the situation will be more crucial and the reduction in quantity and/or quality could be considerably high. In the other side, the figure of fish stock potency does not indicate the available fish for further processing yet. Therefore, the figure will be more meaningful when it is corrected by the loss. Until recently, post-harvest fish loss in Indonesia is estimated as high as 30%; this figure has been used as reference for decades eventhough many effort has been done to reduce the fish loss. This situation indicates very serious problem since no further information how the data or the figure had been quantified. This figure needs...

Compared to chitosan which is soluble in weak acid, the CMCts is soluble in water and it becomes more desirable in many applications both in pharmaceutical and food industries. Chitosan as the raw material of CMCts was made from chitin deacetylation. The reasearch aimed to study the effect of chitin deacetylation methods and concentrations of sodium hydroxide in the alkalination process on the characteristics of CMCts produced. Three deacetylation processes were applied in the production of chitosan, i.e. treatment with 60% NaOH at 70 o C for 2 and 3 days, and treatment with 60% NaOH at ambient for 5 days. Whereas, the alkalination process was conducted using NaOH at the concentrations of 20, 30, 40 and 50%. The carboxymethylation of chitosan was carried out using monochloroacetic acid with the ratio of chitosan to monochloroacetic acid of 1 : 1.5 (w/w) at 50 o C...

This study used raw material of sap-free seaweed for ATC processing. Sap-free seaweed is a seaweed which thallus has been extracted with liquid known as sap. The use of sap-free seaweed as an ATC product is constrained by its low quality, so an effort to improve its quality is needed. Therefore the obejcetive of this Research was to get the optimal conditions of ATC processing. Experimental data were designed and analyzed using Response Surface MethodologyCentral Composite Design (RSM-CCD) using Design Expert 10.0.7® program. The optimization of ATC processing involved three components that were considered influential, namely KOH concentration, temperature, and processing time. Recommendation for optimal conditions issued by RSM-CCD on ATC processing from sap-free seawee d were 6 % KOH concentration at 75 oC for 120 minutes (93.1% desirability). The results of the response analysis...

Chi with a degree of deacetylation (DD) of 84% complexed with Alg at a mixing ratio (MR) of 0.2 was used to study Chi-Aig concentration and treatment time protein recovery effects. Insoluble SWW solids were removed by centrifugation and the supematant was then adjusted to pH 6. Flocculation at 20°C using Chi-Alg at 20, 40, 100 and 150 mg/L SWW was aided by 5 mm agitation and holding for 30 mm, lh and 24h. Concentration had an effect between low (20 and 40 mgIL) and high (100 and 150 mg/L) levels. Time had an effect between 30 mm and lh but not between 1 and 24 h. Turbidity reduction was affected only by concentration. 100 mg Chi-Alg/L SWW for 1 h achieved 83% protein adsorption and 97% turbidity reduction while lower concentrations yielding higher adsorption Redacted for privacy required longer times. Fourier Trans...

Bakteri yang hidup di limbah yang banyak mengandung protein dan lemak tersebut diperkirakan memiliki kemampuan untuk menghidrolisis lemak menjadi asam lemak dan gliserol sehingga berpotensi untuk dimanfaatkan sebagai bioremedian alami bagi penanganan air limbah hasil perikanan di tempat lain. Penelitian ini bertujuan untuk melakukan penapisan dan identifikasi bakteri lipolitik potensial sebagai bioremedian air limbah perikanan. Penapisan dilakukan terhadap 11 isolat bakteri lipolitik dari air limbah yang diambil dari industri pengalengan rajungan di Cirebon dan pengolahan surimi di Kendal dengan menggunakan media spesifik agar tributirin. Isolat bakteri lipolitik potensial ditentukan berdasarkan zona bening yang terbentuk di sekitar koloni, yaitu sekuran...

Because of less attention and knowledge, wastes become worse. The aim of this study was to discover potential microbial consortium that can degrade protein and fat of liquid waste from fish production processing. The consortiums formula were chosen from bacteria that have the highest specific growth. Formulation A which degraded soluble protein than others. Formulation of B which degraded fat than others. All formulation had pH in range are 6 - 9. Liquid waste which outoclaved had degraded protein, soluble protein and pH parameters

The present study is the first assessment of the floating plastic debris in Jakarta Bay based on an at-sea survey. The study aimed to overview the accumulation of plastic debris in different zones (west, middle, and east) of the bay as the impact of wet and dry seasons. The results showed that plastic debris was found in most sampling stations with a maximum concentration of 10,300 and 7,400 items/km2 in the wet and dry seasons, respectively. Based on the plastic types, polyethylene (PE), polypropylene (PP), and polystyrene (PS) were the main accumulated plastic debris in Jakarta Bay with a predominant macro size between 2.5 and 20 cm. According to the plastic applications, packaging and consumer products were the majority of plastic debris at concentrations of 257-1,280 items/km2 and 936-983 items/km2 in the dry and wet s...

The research aimed to identify the opportunities to overcome these problems. The research conducted with the Kaizen analysis approach that seven upstream business nodes were chosen at three locations: two Gracilaria sp. farmers and one Gracilaria sp. trader in Brebes, one Eucheumatoid farmer and one intermediary trader in Serang, also two Eucheumatoid farmers in Sumenep. The results show some inefficiency in several loci in the business lines of intermediate farmers and traders. These include a gap on moisture content (Gracilaria of 2 % and Eucheumatoid of 4 %), productivity of Gracilaria pond 0.6 t ha–1 yr–1 and its by-product is 50 %, while the productivity of Eucheumatoids was 10 %. The quality of dry Gracilaria is one grade only. All result loss of potential margin. Root problem analysis found several external factors out...

However, it is stated that these fish contains high formaldehyde up to 200 ppm, which is strongly suspected naturally due to deterioration. Furthermore, the aim of this study is to obtain the data of probabilistic health risk assessment due to consumption of opah fish that contaminated with natural formaldehyde. The study was conducted on opah fish (Lampris guttatus) that were analyzed the formaldehyde concentration in it. Along with the consumption data, body weight and the formaldehyde concentration included two others simulations of two times and four times of formaldehyde value, probabilistic dietary exposure was calculated by @Risk and produced some data regard to health risk. The result showed that Opah fish caught in Indonesian waters could produce formaldehyde naturally due to deterioration process ranged fro...
