Abstract

According to the results of search and study (Illah Sailah, 2008) there is a difference of needs and development as well as the point of view of hard skills and soft skills between the world of work and college at the current ratio of soft skills and hard skills needs in the world of work / business inversely proportional to its development in college. Success in the world of work / effort 80% is determined by the mindset (soft skills) it has and 20% determined by technical skills (hard skills). In Wikipedia (2010) it iswritten that soft skills is a sociological termination for an individual's Emotional Intelligence Quotient (EQ), an ability of how people relate to one another, such as communicating, listening, giving feedback, working together in a team , solve problems, contribute to meetings, and resolve conflicts. However, the condition of university students hasyim asy'ari is not aware of the importance of softskill ability. Therefore, researchers make an application to measure or self-assessing students related to sofskill based on android with dynamic programming algorithm. Because android applications are now mushrooming among young people, especially students. this application can display the score of the value amount of softskill.Keywords: Algorithm Dynamic programming, softskill, Android

Abstract

Salah satu faktor penting dalam budidaya ikan nila adalah ketersediaan pakan yang memadai. Ikan nila (Oreochromis sp.) merupakan ikan air tawar yang memiliki nilai ekonomis tinggi dan banyak dibudidayakan, namun pembudidaya sering mengalami kendala karena harga pakan yang tinggi. Hal ini terjadi karena bahan baku pakan seperti tepung ikan masih diimpor. Untuk mengatasinya perlu alternatif sumber bahan baku salah satunya adalah memanfaatkan limbah kepala ikan teri. Penelitian ini bertujuan untuk memperoleh formulasi pakan yang terbaik untuk pertumbuhan ikan nila, menggunakan Rancangan Acak Lengkap dengan 5 perlakuan dan 3 kali ulangan A (tepung ikan 100%), B (tepung kepala ikan teri 25% dan tepung ikan 75%), C (tepung kepala ikan teri 50% dan tepung ikan 50%), D (tepung kepala ikan teri 75% dan tepung ikan 25%), E (tepung kepala ikan teri 100%). Data yang diperoleh dianalisis ragam dan dilanjutkan dengan uji BNT. Parameter yang diamati berupa: pertumbuhan, retensi protein, feed convertion ratio (FCR), dan survival rate (SR). hasil pengamatan menunjukkan bahwa penggunaan tepung kepala ikan teri dalam pakan buatan pada perlakuan E memberikan pengaruh nyata dibandingkan perlakuan A, B, C, dan D yakni didapat pertumbuhan, dan retensi protein tinggi, sedangkan nilai FCR rendah. Hal tersebut menyatakan bahwa tepung kepala ikan teri mampu menggantikan tepung ikan.KATA KUNCI: Ikan nila, limbah ikan teri, pakan.

Abstract

Our previous study found that KLU 11.16, isolated from shrimp waste secreted chitinolytic enzymes. The crude enzyme was interesting since their chitooligosccharide was able to inhibit some pathogenic bacteria. In this study we report a purification and characterization of the chitosanase enzyme produced and the identification of the KLU 11.16. Purification of the enzyme was done two steps by ion exchange chromatography followed by gel filtration. Two out of 4 peaks from Gel Filtration step, i.e. fraction 16 and 33 were capable of hydrolyzing 100% deacetylated chitosan, indicating that both fractions contained chitosanase enzyme. The enzyme from fraction 16 had approximate molecular weight of 98.3 kDa. The enzyme worked optimally at temperature of 300C, and pH 6. Addition of Ca2+, Fe2+, K+, Na+ ions in the form of Cl2 salt and detergent Triton X-100 increased the enzyme activity, while Co2+, Mn2+ and Zn2+ ions in the same concentration decreased the enzyme acitivity. Addition of EDTA and SDS significantly decreased the enzyme activity. Molecular based identification revealed that KLU 11.16 was 99% similar to Aeromonas media.

Abstract

Abstract. The snubnose pompano Trachinotus blochii is one of the important commercial fishery commodity in the Indonesian market. The increasing of the market demand has led some efforts to increase the production of this fish. So do the increasing need for green mussels Perna viridis meat. Therefore it is necessary to evaluate the performance of both species in the polyculture system by using raft culture. This study aims to compare the growth performance of snubnose pompano cultivated on a monoculture system and polyculture within green mussels in a raft system. The parameter observed was the differences in the  growth performance of both species and the increase in total weight and survival (SR) of the fish. The results showed that the growth of snubnose pompano did not provide a significant difference in the growth of both cultivating systems whether in monoculture or polyculture system, likewise the shell length and width of the green mussels. We conclude that it is profitable to cultivate both organisms on a polyculture system because it can harvest both green mussels and snubnose pompano together in a period.Keywords: Snubnose pompano, green mussel, monoculture, polyculture, raft, growth Abstrak.

Abstract

 The study proposes the compensation and restitution regulations which should be oriented to protect the victim of crime. Although most regulations have been adopted the right of the victims to receive the compensation and restitution, but this study finds that there are some weaknesses in such regulations. Hence, compensation regulation should be specifically focused on the fulfillment of the right of the victims of crime. It shall not depend on court decisions, but such compensation should be provided even though the victims ceased before the court proceeding has started, or even if he or she wrongly arrested by police. This compensation is only to cover material losses and traumatic stress recovery cost. It could be paid directly monthly/yearly and could be converted to other form of compensation. Restitution refers to the paradigm of restorative justice. In Indonesia, restitution should be based on final and binding court decision. If the perpetrator does not want to provide it for the victim, he/she has moral obligation to provide it for the victim oven without inkracht court decision, and this could be used by the judges to pardon the perpetrator. Restitution shall be enforced for all criminal offences which resulting direct and indirect losses for the victims. Restitution is not merely about monetary values but moral obligation of the perpetrator to recover the victim’s condition.
