Abstract

DOWNLOAD PDFProses  absorpsi  foton  dengan  energi  tertentu  akan  mengeksitasi  elektron  darikeadaan energi yang lebih rendah ke keadaan energi yang lebih tinggi. Untuk menentukankoefisien  ini  secara  eksperimen  terutama  karena  adanya  pengaruh  interferensi  optis  daripola-pola  transmitansi  dan  reflektansi.  Tujuan  penelitian  ini  adalah  untuk  menentukanbesarnya absorpsi lapisan tipis In2O3: SnO2dengan berbagai kadar oksigen yang diberikanpada saat deposisi. Proses pelapisan dilakukan 90% berat In2O3 dan 10% berat SnO2padasubstrat kaca dengan cara sputtering. Pada saat sputtering dilakukan penambahan oksigentertentu  yaitu  2,50%,  3,70%,  5,10%,  6,15%  dan  8,90%  yang  dilakukan  deposisi  padatemperature 1750C. Hasil analisis teramati adanya pergeseran interferensi dan transmitansike arah panjang gelombang yang lebih pendek sebanding dengan kenaikan kadar oksigen.Pada  kadar  oksigen  2,50%  dan  3,70%  koefisien  absorbsi  makin  naik,  tetapi  pada  kadaroksigen  5,10%,  6,15%  dan   8,90%  koefisien  absorpsi  mulai  menurun.  Perlakuan  kadaroksigen  pada  saat  deposisi  lapisan  tipis  ITO  dapat  mempengaruhi  koefisien  absorpsilapisan tipis yang terbentuk.Kata kunci : Kadar oksigen, koefisien absorpsi

Abstract

DOWNLOAD PDFTelah dilakukan penelitian Analisis pedigree terhadap sifat cadel. Cadel merupakanketidakmampuan melafadskan huruf ”r”. Umum dijumpai pada anak usia BALITA (bawahlima tahun), tapi sering pula terdapat pada orang dewasa. Cadel yang dialami oleh orangdewasa  umumnya  disebabkan  oleh  pengaruh  lingkungan  seperti  psikoedukatif  danpsikokultural, dapat pula disebabkan oleh faktor penyakit seperti menderita down syndrom,stroke,  atau  pada  penderita  penyakit  yang  berhubungan  dengan  syaraf.  Adapun  yangdisebabkan  oleh  faktor  herediter  belum  diketahui  secara  pasti,   sehingga  penelitian  inibertujuan  untuk  menentukan  sifat  cadel  yang  disebabkan  oleh  pengaruh  herediter  danuntuk menentukan pola  pewarisan cadel. Penelitian ini dilakukan sejak tahun 1994  yangkemudian  dilanjutkan  lagi  tahun  2012  di  Propinsi  Sulawesi  Selatan  tempat  sampelberdomisili. Sebanyak tiga silsilah keluarga hasil penelitian yang telah disusun dari datayang  memenuhi  kriteria  dianalisis  untuk  menentukan  sifat  cadel  yang  disebabkan  olehfaktor  herediter  dan  menentukan  pola  pewarisan  sifat   cadel.  Pola-pola  pewarisan  sifatyang digunakan adalah yang umum ditemukan pada manusia. Dibuat suatu asumsi bahwa “Karakter  A  diturunkan  menurut  pola  b”  dalam  menentukan  pola  pewarisan  cadel,kemudian melalui fenotip yang terdapat pada silsilah keluarga dilihat kesesuaian denganasumsi. Hasil penelitian menunjukkan bahwa cadel dapat disebabkan oleh faktor herediterdan diwariskan menurut pola resesif autosomal.Kata kunci : Analisis pedigree, cadel, resesif autosomal.

Abstract

DOWNLOAD PDFThis study discusses the application of SEM in the field of education on the relationship between quality of service (ξ1), satisfaction (η1), confidence (η2) and loyalty (η3) are also basic concepts SEM, structural equation modeling and make a path diagram. This study aimed to determine the relationship of service quality, satisfaction, trust and loyalty student at UNM Department of Mathematics and knowing intervening variable between service quality and loyalty. Using SEM analysis found that the quality of service significantly influence satisfaction and trust while the quality of service does not have a significant  direct  influence  loyalty. Satisfaction was also no significant  effect on loyalty. Structural equation modeling results are , , . From the analysis it can be concluded that loyalty can be built with good quality service with confidence as an intervening variable. So, with good service will lead to student confidence. Once there is trust there arise loyalty. Key words: SEM, service quality, satisfaction, trust, loyalty.

Abstract

DOWNLOAD PDFAn understanding of constructivism would be complete when it could be implemented within professional practice. Taking into account the current philosophies in mathematics education, I can see a possible setting which can be generated by using constructivism as a mediator. This mediator is used to set the context in which the processes of teaching and learning of mathematical proof are conducted.   Key words: Constructivism, mathematical proof, teaching and learning.

Abstract

DOWNLOAD PDFThe study has been conducted to determine whether there are influences and interactions of type of mulberry Morus multicaulis and  Morus cathayana to cocoon production in the silkworm (Bombyx mori L.) Local varieties, Japan, China and Rumania. Study was arranged in Complete Randomized Design (CRD), with a factorial design of two types of mulberry leaf with four varieties of silkworms with three replications. The treatments combination were 24 treatments. The parameters of this research included cocoon weight, cocoon leather weight, fiber length and fiber weight. The results showed that Morus cathayana have cocoon 1.188 g weight, cocoon skin 0.214 g, 1015.027 m of fiber length and fiber weight 0.218 g in silkworm Romania variety (A2B4), when compared with Morus multicaulis produced cocoon weight as 1.143 g, and cocoon skin 0.197 g, fiber length 944.745 m, and fiber weight 0.199 g in silkworm Romania variety (A1B4). Therefore after data were analyzed with LSD (α=0.05) Morus multicaulis and Morus cathayana to silkworm Local, Japan, China and Romania and the interactions between mulberrys with four varieties of silkworm cocoons have real impact on weight, heavy leather cocoon and fiber length and weight of fiber produced.   Key words:  Morus multicaulis, Morus cathayana, production of silk cocoon, silkworm

Abstract

DOWNLOAD PDFDescriptive research was done to know the contents of lead (Pb) in tea leaf (Camellia sinensis) at top, under hills as well as soil of tea plantation at top and under the hills in Malino district. The Variable of these researches was lead content in tea leaf at top and under the hills. Another variable was soial of tea plantation at the top and under hills. The samples were taken from six stations, which were 1, 2, and 3 stations at top hill and 4, 5 and 6 stations at under hill. The leaf sample that taken was small sprout. Lead content was analyzed by using Absorption Automatic Spectrophotometer.  The results showed that mean content of lead in tea leaf at top hill was 3,4 µg/kg and mean content of lead at under hill was 5,7 µg/kg. The mean content of soil at top hill was 8,4 µg/kg and the average Pb content of soil at under hill was 7,5 µg/kg. After calculated by Mann-Whitney test found that there was difference Pb between concentration in the leaves on tea plants at top and under hills. There was no differences between lead concentration in soil at the top and under of hills. Test correlation with Spearman Rank found that there was correlation between Pb contents in the leaf of tea plants on the hill with soil at the hill. Study also showed that no correlation between lead content at tea leaf and soil at under of the hill.   Key words: Tea leaf (Camellia sinensis),  lead (Pb),  Malino tea plantation.
