Abstract

Timbal (Pb) merupakan jenis logam berat yang bersifat toksik, yang ketika masuk ke dalam tubuh akan terikat dengan protein sehingga hanya sedikit yang diekskresikan (Sudarwin, 2008). Ikan lele merupakan jenis ikan tawar yang banyak dikonsumsi oleh masyarakat. Selain kandungan gizinya yang  baik,  harga  ikan  lele  juga  terjangkau. Analisis logam  berat  Pb pada ikan  lele  yang dibudidayakan  di  Kota  Pekalongan  diharapkan  mampu  menjamin  hasil  budidaya  ikan  lele  yang akan  dikonsumsi  oleh  masyarakat  bebas  dari  kandungan  logam  berat  yang  berbahaya,  sehingga aman  dikonsumsi  dan  menyehatkan.  Sampel  logam  berat  Pb  diambil  dari  empat  wilayah pembudidayaan  di  Kota  Pekalongan,  yakni  Tirto,  Dekoro,  Jenggot,  dan  Panjang.  Kandungan logam  berat  Pb  dianalisis  dengan  menggunakan  metode  spektrofotometer  serapan    atom (AAS). Hasil analisis menunjukkan tiap sampel ikan lele hasil budidaya empat lokasi di Kota Pekalongan memiliki  kandungan  logam  berat  timbal  (Pb)  pada    rentang  8,3 – 39,45  μg/kg  bb.  Kadar  logam berat  Pb  hasil  analisis  tiap  sampel  masih  berada  di  bawah  ambang  batas  maksimal  kandungan logam berat Pb. Kata kunci: ikan lele, Pb, pekalongan

Abstract

Public housing issue in Indonesia,  particularly in the urban area, has become a  widely discussed issue,  whether  related  to  land  limitation,  increasing  price,  or  the  developer  promises  that sometimes differ  from the existing facts. Whatever the problem is, the  housing requirements  for the predominantly Moslem population should be the major consideration, before other aspects are considered.    The  fact  is  that  this  matter  has  been  neglected  due  to  the  consideration  of  bigger people  needs.    Other  than  that,  the  highly  increasing  price  should  be  reconsidered  because  it  is related to purchasing power of the people. In other words, in the end, people do not always have an option to choose the best they think because at the same time they have to fulfill their basic needs. This writing attempts to provide an alternative concept that can be applied in creating a conducive housing  for  Moslem  families.  It  is  expected  that  this      concept  can  be  applied  in  the  general housing planning. Key words: rooms, housing, Moslem

Abstract

Cooperative  Principle  is  a  principle  which  used  to  become  an  effective  communication.  It  often appears in the conversation. Cooperative Principle  was proposed by Grice in 1975. It consists of four maxims in the conversation. Those are quantity maxim, quality maxim, relevance maxim and manner  maxim.  The  observance  of  the  four  maxims  used  in  order  to  gain  the  meaningful conversation. Novel entitled  “Harry Potter  dan Batu  Bertuah”  is one  of the  most popular novels. The conversations among the characters in that novel is interesting to be analyzed. The purposes of the study are to identify the maxims which observe the cooperative principle in term of meanings. The  method  used  in  this  study  was  descriptive  qualitative  with  cooperative  principle  analysis approach.  The  objects  of  the  study  were  43  conversations.  To  analyze  the  conversations  which observe the maxims are done by interpreting the meanings of the conversation. The findings of the conversations which observe the cooperative principle are as follow: 60.5% utterances observe the maxim of quantity; 16.3%  utterances observe the  maxim of relevance; 16.3%  utterances  observe the  maxim  of  manner  and  7%  utterances  observe  the  maxim  of  quality. The  finding  is  also suggested as a recommendation in the teaching learning process for the advanced learner level and the  senior  high  school  level. This  findings  can  be  applied  in  the  advanced  learner  level  in transferring  the  material  of  speaking.  Another  recommendation  is  suggested  for  the  senior  high school level in the English subject. It can be applied in the discussion of the material and question and answer session between the teacher and the students.Keywords: speech act, conversation, cooperative principle

Abstract

It has been found the fact that natural dyes are not environmentally friendly dyes if they are directly discharged into the water without undergoing processing. Theoretically, both synthetic dyes and natural dyes have the same opportunity to cause pollution of aquatic ecosystems because they have the same functional groups. So far, natural dyes are considered environmentally friendly not because of the low waste pollutant parameters, but because there is a process of reuse of the remaining dyed water. The process of reusing the remaining dye solution can reduce the volume of liquid waste discharged into the water. This study aims to reuse of the remaining water dyed synthetic of vat dyes for the process of making batik. The quality of the staining results is evaluated by color fastness test on washing and rubbing. The reusing synthetic of vat dyes group is done for coloring cotton fabrics. The fabric color evaluation stage is carried out to test the color intensity and fastness of synthetic dyes of vat dyes group if the dye is reused in the batik process. Color intensity test was carried out by UV-PC spectrophotometer, color fastness test on washing use gray scale, and color fastness test on dry rubbing use staining scale. Based on the color intensity test, the process of reusing the remaining dye solution of the indantren navy blue R is still optimal if used on the same day. Reusing the remaining dye solution the next day gives a large value of color intensity value from the use of the dye solution for the first time. Indantren navy blue R color substances are relatively resistant to hydrolysis reactions during the dissolution process in water.
