Abstract

Penelitian ini dilakukan untuk mengetahui pengaruh penambahan serbuk serasah lamun (seagrass) terhadap pasir pada nilai kuat tekan dan absorbsi air eco-batako.Metode yang digunakan dalam penelitian ini yakni eksperimen dengan sampel eco-batako (20 x 10 x 6) cm dalam 4 variasi penambahan serbuk serasah lamun.Variasi pertama tanpa penambahan serbuk serasah lamun (0%), kedua dengan penambahan 5%, ketiga dengan penambahan 15%, dan yang keempat dengan penambahan 25%. Pengujian kuat tekan dan absorbs air dilakukan pada eco-batako umur 28 hari dengan sepuluh kali pengulangan dan diambil nilai rata-ratanya. Hasil penelitian menunjukan nilai kuat tekan untuk setiap variasi adalah 12,102 MPa untuk yang tanpa penambahan serbuk serasah lamun (0%), 11,011 MPa untuk penambahan 5%, 7,6044MPa untuk penambahan 15%, dan 5,3872MPa untuk penambahan 25%. Untuk data pengujian absorsi air adalah 12,439% untuk yang tanpa penambahan serbuk serasah lamun (0%), 13,81% untuk penambahan 5%, 15,215% untuk penambahan 15%, dan 16,019% untuk penambahan 25%. Kesimpulan yang diperoleh adalahsemakin banyak konsentrasi penambahan serbuk serasah lamun semakin rendah nilai kuat tekan eco-batako dan sebaliknya semakin sedikit penambahan konsentrasi serbuk serasah lamun dalam eco-batako semakin rendah daya absorbsi airnya

Abstract

Aspergillusniger is one type of mold that has a high ability to produce cellulases. Cellulases in the manufacturing process required the right conditions in order to obtain optimum quality and quantity. This study aims to determine the effect of different concentrations of inoculum and incubation time on cellulases activity of Aspergillusniger.The method used was a quantitative experiment with pattern completely randomized design(CRD) two factorial. Treatment research includes different of inoculum (K) which are 10%(K1), 15% (K2), 20% (K3) and incubation times (T) are 5 days (T1), 7 days (T2), 9days (T3). The datawere taken from the treatment is glucose levels of cellulases activity using theNelson Somogyi method. Analysis data using ANOVA two lanes with 5% of a significance level and continued to test Honestly Significant Difference (HSD). The results showed that: Fhit>Ftabso that there are significant differences in inoculum concentrations and incubation time of cellulolytic activity from Aspergillusniger.The highest glucose levels obtained in K3T1 treatment (20% of concentration and 5days of incubation time) with 0.072%.

Abstract

Education is an important role in improving human resources. SDN Sugihwaras 2 Maospati have adequate facilities and infrastructure, but its use is not maximized. Such conditions make the learning  in the classroom in which there are still many students spoke with fear, students tend to give silent resulted in low learning outcomes. Implementation of education are encouraged to use effective learning media that give pleasure to support student learning outcomes give liveliness. Based on these problems, researchers conduct studies in SDN Sugihwaras 2 Maospati. Media monopoly in learning aims to enhance the activity and learning outcomes third grade students in sci ence subjects. The research was conducted in the SDN Sugihwaras 2 Maospati. Data collection techniques were used that observation, documentation, tests, and interviews. Results showed that the average use of  monopoly can enhance the activity of learning outcomes. Data were obtained that the learning outcomes of the first cycle completeness 45% give students who are not on 55% due to the secondcycle increased to 75% Students who complete 25% give students conclusion is not. Liveliness to the  results of the first cycle 20% liveliness students are active, 45% of students are quite active, give 35% of students are less active. In the second cycle there is an increasing involvement of the student to be 70% of active students. It can be concluded there is an increase learning outcomes and student activity by monopoly media.

Abstract

This study aims to investigate the influence of concentration and soaking time of lactic acid toward glucose and quality of canna’s starch (Canna Edualis Kerr). The research method using a completelyrandomized design (CRD) with 3x3x3 factorial and three replications. The repetition are K1L1, K1L2,K1L3, K2L1, K2L2, K2L3, K3L1, K3L2, first K3L3. The first factors is variations of concentration (K)include 1%, 1.5%, 2%, the second factor is soaking time (L), there are 60 minutes, 90 minutes, 120minutes. Collecting data by calculating the glucose level using titration method with Na. Organoleptictests include color, odor, texture and level of preference to the 15 panelists using a closed questionnaire.Best organoleptic test are K3L3 treatment (2% of lactic acid concentration with 120 minutes soakingtime) with a total value of 82.5 while the lowest are K3L1 treatment (2% of concentration with a 60minutes of soaking time) with 48.5 of values. Data analysis shows the variation of concentration affect onglucose levels (P = 0.000 <0.05). Soaking time affect on glucose levels (P = 0.000 <0.05) .There are anyinteraction effect of concentration and soaking time on glucose levels. Based on the results showed thatthe highest glucose levels found in K1LI treatment with 1% of lactic acid concentration and 60 minutes ofsoaking time. As for the glucose concentration was lowest for K3L3 treatment with 3% of lactic acidconcentration and 120 minutes of soaking time. The results of this study are used as material preparationBiochemistry lab manual.

Abstract

The quality  of products  of a  Teacher Training  Institution  does not merely  depend  on the grade point everage they pursue,  but also on the competitive   advantage  they gain during  the learning   process to fight for position  and apply the pedagogical  priciples  in the work market  share.  The  quality of teaching  and' learning  process   in the campus  should  be then  fitted to  such  needs  of  the market   share, which  can  be  done  by sending lecturers   to  schools   as  apprentice teachers.This Peer Grant Research is aimed at: 1) developing  the quality of lecturers'  instruction, 2) developing relationship between IKIP PGRI Madiun   and  the  peer  institutions,   3) searching   and  implementing alternative     strategies    for  teaching    and  learning    effectiveness. Collaborative   teaching  between  lecturers  of IKIP PGRI Madiun  and teachers  of SMP N 11 Madiun  is designed  to: 1) observe  the existing condition  of classes,  2) discuss  for developing  alternative  strategies, 3) arrange and implement  the instructional  design, 4) conduct teaching and learning  process,  and 5) suggest  evaluation.  Class  observation, questionaire   and interview  are used to draw data from 7 subjects  in research,   i.e.:  Bahasa   Indonesia,   English,   Natural   Science,  Social Science,  Math, Civics  and Counseling.The  results   of  the  research   can  be  outlined   as  follows:   1) lecturers   develop   their  classes   by  inspecting    and  implementing directly the instruction  in real scholls'  classes, 2) identification  against weaknesses  in schools'  classes can be arranged for further evaluation, 3) the campus  develops  teacher  training  instructional   designs  based on field inventions,  4) collaborative  team invent alternative  strategies in classes, 5) lecturers experience real schools classes so as to develop their instructional design, 6) teachers are motivated to continously develop their teaching to gain optimal out-come.
