· The first time came to Japan

Japan is one of the world’s major economic and cultural powers. Located in the Pacific Ocean, it’s Asian neighbors include the People’s Republic of China, North Korea, South Korea, Russia and Taiwan.Japan is an archipelago consisting of four major islands called Honshu, Hokkaido, Kyushu and Shikoku and over 3000 smaller islands. Japan is one of the leading nations in the fields of scientific research, particularly technology, machinery and biomedical research. Japan’s global technological contributions can be found in the fields of automobiles, chemicals, electronics, earthquake engineering, machinery, optics,semiconductors, metals and industrial robotics

Japan is a constitutional monarchy where the power of the Emperor is very limited. Power is held chiefly by the Prime Minister of Japan and other elected members of the Diet, while sovereignty is vested in the Japanese people. Japan is sometimes referred to as the “Land of the Rising Sun”.

Hokkaido is an island at Japan's northern extremity, surrounded by sea in all directions. It is an extensive land, accounting for 22% of Japan's total land area. Low humidity makes the summers pleasant, while in winter you can enjoy winter sports. The island is gaining popularity as a tourist destination throughout the four seasons.

March 2^nd, 2015—the day is my first time came in Country of Sakura (Japan), i felt so amaze because i can look directly with my eyes—look the country that everyday i dream can steping my foot in ths country. Not only felt amazed, but also the weather is so cold when i came here. Of course, because actualy now in Hokkaido still in winter.

· Arrive on Hokkaido University

Hokkaido University is an international university with a long tradition of excellence in teaching and research, attracting outstanding staff and students from Japan and around the globe. Our objective is to attract the best students, regardless of their origin or financial circumstances, and to offer them a top quality education equal to any in the world.(Prof.Keizo Yamaguchi,2013)

Since first admitting students in 1876, Hokkaido University has grown rapidly. Today we enrol approximately 18,000 students, including many international students from more than 85 countries. Originally an agricultural college set up by Dr. William S. Clark , Hokkaido University has upheld four philosophies from its establishment – namely The Frontier Spirit- a spirit embodied in us all allowing us to blaze new trails in research and education, Global Perspectives – giving us the will to understand different frameworks and values from around the world, All-round Education – teaching us a wide range of skills fostering a rich humanity, and finally Practical Learning – valuing authenticity in the search for universal truth. Passed down through the ages, it is these four unwavering philosophies that have formed our DNA, and make this university the esteemed institution that it is today. .(Prof.Keizo Yamaguchi,2013)

Kim Hyong Jun as my supporter pick up me in Chitose Airport and guiding me until we arrived to the college (Kigaku Hokudai). Snow Storm faced me when my foot step the first time in this city, i felt happy but cold, its okay. And finaly i meet my sensei., Shunitz Tanaka Sensei welcoming me with his sweet smile face. And because that i judges my sensei is very kind and nice person. I love him!

· Laboratory Work on Development of Absorbent

1. Effect of pH for Cd²⁺ adsorption

¨ Instructor : Prof. Shunitz Tanaka and Endo-san (M2)

¨ Place : Tanaka Lab (GSES C604 and C606)

¨ Purpose : To investigate effect of pH of sollution in order to determine the ability and optimum condition for biosorpstion

Sasa (abundant plant in Japan) : to increase the adsorption capacity., sasa powder was modified with citric acid 1,3 M and then heated at 150*C.,the result from this process is FMCA (fresh modified with citric acid)

¨ Result

No	Sample	pH	Shaking Time	Weight (mg)	Concentration (ppm)	Dillution Time	Conc. Real	Efficiency (%)
1	ph 2	2	1,5 hours	100.0	2,0065	5	10,0325	0
2	ph 3	3	1,5 hours	100.0	0,533	5	2,665	73,35
3	ph 4	4	1,5 hours	100.0	0	5	0	100
4	ph 5	5	1,5 hours	100.3	0	5	0	100
5	ph 6	6	1,5 hours	100.0	0	5	0	100

2. Study of adsorption for anionic dyes amd magnetic separation by magnetic chitosan

¨ Instructor : Prof. Shunitz Tanaka and Yasuyuki Narita (M2)

¨ Place : Tanaka Lab (GSES C604 and C606)

¨ Purpose : Study of Adsorption Theory and Examined Adsorption Ability of Magenetic Chitosan Towards Anionic Dye

The advantage from hybrid material of chitosan and magnetite (Fe₃O₄) is collectable easily from aqueous solution using magnet.

The adsorbate is Methyl Orange(MO).

3. Electrokinetic Remediation

¨ Instructor : Prof. Shunitz Tanaka and Miyamura-san (M2)

¨ Place : Tanaka Lab (GSES C604 and C606)

¨ Purpose : To investigate remediation ability with use electrokinetic in sample of soil (white clay)

¨ Method :

After get the data from AAS, we calculated amount of Pb that contain in every fraction (1-2-3-4-5-Cathode-Anodhe-Overflow). The total leads are 5,6348 mg.,it show that the experiments is failed because target total amount of leads are 18mg. Failure reason is :

• Base Condition : Pb has been change into Pb(OH)2., hydrocsil leads cant be detect in AAS

• The Carbon is break : Carbons are contain much of Pb.,if the carbons are break, so maybe can adjust more Pb into citric acid solution

4. Selectivity of Prussian Blue for Separating Cesium Ion from Aqueous Solution.

¨ Instructor : Prof. Shunitz Tanaka and Moriya-san (M2)

¨ Place : Tanaka Lab (GSES C604 and C606)

¨ Purpose : To learning about selectivity

¨ Method :

Solution standar must contain 1000ppm of potasium ion for measuring cesium ion. Sodium ions disturb the measuring cesium ion. So, we make two types of standar solution, one is not contain sodium ion, other one is contained sodium ion. The cesium concentration in standar solution are 0~5 ppm

5. Adsorption Test of Dyes Using Alginate Gel Beads Including Activated Carbon

¨ Instructor : Prof. Shunitz Tanaka and Inaba-san (M2)

¨ Place : Tanaka Lab (GSES C604 and C606)

¨ Purpose :

1. Preparation Solution

2. Adsorption of pollutant (methylene blue, phenol red) using alginate gel beads including activated carbon

3. Measurement of absorbance using spectrophotometer

¨ Method :

v Adsorption tes of dye using alginated beads

v Reagent :

Ø 1,0x10^-5 M Mehtylene Blue

Ø 3,0x10^-5 M Phenol Red

· Hokkaido Indonesian Student Association Sciencetific Meeting

The international community’s response to population growth and development challenges over the next decades will greatly affect on the quality of life of present and future generations. Action to maintain the natural resources and promote the science and technology to humanity and prosperity in general aspect will be particularly crucial.

The world’s population, now about 7 billions, is growing rapidly. Many of the resources on which future generations will depend are being depleted at alarming rates and pollution is intensifying, driven by wasteful consumption, the unprecedented growth in human numbers, persistent poverty, and social and economic inequality.

Indonesia is one of the large countries in the world with 245 million people, has great potency in the several areas such as agriculture, forestry, marines, renewable energy and human resources. Sustainability concept should be involved during the utilization of these resources to achieve prosperity among Indonesia citizens. A sustainable development would improve the quality of human life, which then could be accessed by all individual citizens and future generations. Researchers as agent of innovation could play important and significant contribution to implement these concepts not only during the research activities but also in the application. In order to attain that purposes, the collaboration of multidisciplinary scientist are strongly needed. Indonesia Student Association in Hokkaido (PPI-Hokkaido) which is consist young talented research in the numerous area such as science, engineering, environmental, forestry, agriculture, fishery and social sciences has high motivation to participate in developing new idea and concept, new design technology for human need prosperity among Indonesia citizens.

Here, PPI-Hokkaido through the 12th Hokkaido Indonesia Scientific Meeting (HISAS 12) tries to fulfill their passion in contributing the nations’ future.
