Present Condition and Issues of the Food Recycling Loop in Japan

Presented by Dr. Izumi Yano; Date: 2012/11/03

In Japan, 36% of all food supply, which around 36.6 million, became as waste.  More than 12.7 million ton are product of soybean, meat, wheat, grain and others agriculture product during manufacturing and processing phase.  For example, whole sale market food waste encompasses fruit 60 ton and fishery product 720 ton; which are used for feed and compos.  Avoiding food loss was needed to develop standardization and sorting systems.  As a result, national system of food recycle was recommended to reduce food waste.  It was inaction in law amended in 2007 and it also promoted the new food recycle law for industries to raise recycling target by year 2012, as follow: 85% food manufacture, 70% food whole sale market, 45% food retailer, and 40% for food services industries.  As a conclusion, the loop is indispensable for food recycling and the biggest problem which consumer’s lack of awareness of recycle food waste resources.  In the future, it is needed to develop or seek from recycle system to recycle loops.

Novel Approach to Monitor Red Tide Status and Its Application for Red Tide Prediction

Presented by Kazuhiko Koike, Tato Arimoto, Maung Saw Htoo Thaw; Date: 2012/11/02

Mass mortalities of fish cage caused by red tide remain a serious problem in Japanese waters.  In 2009 and 2010, red tide led severe yellows tail kill, equivalent to a so far loss of 8.7 billion JPY in the Arieke and Yatsushiro Seas.  Avoiding mass killer of fish, it is need the new method of red tide happen.  One of novelty approach use the pulse amplitude modulation (PAM).  This study objective is PAM flourometry development for phytoplankton survey and its testing usefulness for red tide prediction.  This research was conducted in Kure Port-Hiroshima Bay in the period 11 April to 19 August 2010; Tachibana Bay and Ariake Sea on July 2012.  PAM method was used to analyze maximum photo-energy yield (Fv/Fm) in dark adapted photosystem II, and the same time actual quantum yield (ᶲ II) under illumination of various light regimes to produce electron transportation rate (ETR).

As result, using the indicato Fv/Fm and ETR, Chatonella blooms were found in the sampling occasion at Tachibana Bay and Ariake Sea.  Fv/Fm resulte has negative correlation with water quality and significant correlation with PO4-P and dissolved in-organic nitrogen.  On other hand, ETRmax, assumed from relationship between the light regimes and each corresponding ETR, increased almost one week prior to the blooming of dinoflagellate and Heterosigma.  Therefore, ETRmax would be usable for primary prediction for such phytoplankton blooms because it has advantage for the value of surface water when diatoms dominant or high at the middle or deeper water for flagellate. As recommendation, this research suggested that the vertical measurement can be used for giving a warning whether blooms of diatoms or flagellate would be forthcoming.

Specific Growth and Micro Elements Absorption of Orange Jasmine Under the Iron Deficient Environment

Presented by Cahyowulandari; Date 2014/01/15

Some calcareous soils are not suitable for citrus growth, including in Indonesia.  The best alternative for this type of soil is to introduce Fe to fertilize it for sustainable citrus farming.  Orange jasmine, Murraya sp, use Fe efficiently.  This research objective is to explore iron deficient tolerance response and soil calcareous.  Experiment 1 shown that increase of root biomass compare to those under sufficient Fe condition and flying dragon tended to decrease.  Meanwhile, experiment 2 shown that root growth of orange jasmine tent to increase under Fe condition.  And experiment 3 pointed out that orange jasmine could maintain the dry weight and total plant weight.  As a conclusion, food biomass increasing was since in calcareous soil as similar as in Fe deficient and it can grow in low level Fe and micro element.

Seaweed Production and Supply Chain in Indonesia

Presented by Achmad Zamroni; Date: 2012/08/27

Government of Indonesia has developed seaweed cultivation as alternative livelihood for fishermen. Several project such as Marine Resources Evaluation and Planning (MREP), Sagara Anakan Concervation and Development Project (SACDP), Coastal Resources Management Project (MCRMP), Coral Reef Rehabilitation and Management Project (COREMAP), and Marine Coastal Resources and Management Project (MCRMP) had implemented in recent 10 years, which aimed to improved economic of poor fishermen. Seaweed cultivation is one activities that it was concerned by all those projects.  The research was conducted in Laikang Village, South Sulawesi-Indonesia in 2011.  The objective of this research is to explore seaweed production and supply chain system for supporting alternative livelihood development.

The result of this study show that seaweed farming, mainly Euchema cottoniii species has become the main livelihood for fishermen.  Mostly, seaweed farmer used long line floating method to cultivate E. cottonii.  As consequence, fishermen income increased 50% after they involve and develop seaweed cultivation especially after SNRM Project.  This survey also figure out that 46% of fishing community conducted single seaweed farming and 37% combined seaweed farming and fishing activities.  Another finding that middleman has an important role in supply chain system.  The middlemen supply some production cost such as seed for seaweed farming, as well as they buy the seaweed product after harvesting.  The majority of fishermen expected that the sustain seaweed farming should be supported by good quality environment and marketing chain.

As a conclusion, improvement of livelihood activities for fishermen in Laikang Bay is need to be attention some factors which are supported seaweed farming development, such as change of monsoon, marketing channel, quality of seaweed, farm ownership and commercial price.  High demand of raw materials from domestic and export market, and national policy can be opportunities for future development of seaweed farming and can be expect to improve livelihood of fishermen in Indonesia.
