Abstract

The utilization of fish bone waste so far is processed as mixture of fodder and some into flour. It is less used for humans needs. The processed products food to be substituted of flour a bone of fish products are noodles. This research aims to determine the substitution level on fish bone flour and carrot flour that producing good quality in noodles and find out consumer acceptance toward the addition of fish bone flour and carrot flour have been substituted. The research was designed by employing complete random design with factorial pattern. The parameter of organoleptic quality test was on color, scent, taste, texture and fondness as a whole. The research result reveals that the addition of fish bone flour and carrot flour in treatment A1B2 provides quality value on color, scent and texture that can be accepted by panel.

Abstract

The results showed that there was an interaction between bokashi and vegetable waste fertilizer on N-soil parameters of 1.02%, plant height of 47.25 cm, number of fruits per plant by 4 pieces, fruit weight per plant of 84.04 g, and fruit diameter per plant is 19.96 mm. This study is an experimental study of Randomized Block Design (RBD) consisting of 6 repeated treatments. a = 0 g / polybag, b = 25 g / polybag (5 tons ha-1), c = 75 g / polybag (15 tons ha-1, d = 125 g / polybag (25 tons ha-1), e = 175 g / polybag (35 tons ha-1), f = 225 g / polybag (45 tons ha-1), g = 275 g / polybag (55 tons ha-1). The purpose of this study was to determine the effect of vegetable waste bokashi on fertilizer on N uptake and tomato fruit yield. The thinking framework is a decrease in tomato production. To overcome this we need balanced fertilization in both organic and inorganic fertilizers. This research was conducted in Donggala Kodi Village. Then it did not significantly affect the parameters of  N  Absorption plant, wet weight and dry weight of plants.

Abstract

The objective of this research is to determine Performance Index and Income Over Feed and Chick Cost (IOFCC) of super native chicken given fermented or unfermented of Acacia nilotica seed meal in the diet. The  research  was conducted at Sidera Village, Sigi Biromaru Sub District,  Sigi Regency,  Central Sulawesi Province.   The research used Completed  Random  Design (CRD) with 5 dietary reatments  and 4 replicate cages.    The treatments are: P0: feed without acacia nilotica seed meal,   P1: feed with 5%   unfermented   Acacia nilotica seed meal ,   P2  : feed   with 10% unfermented Acacia nilotica  seed meal ,  P3 :  feed with 5% fermented Acacia nilotica  seed meal , P4 : feed with 10% fermented Acacia nilotica seed meal.   Analysis of variance indicated the effect of treatments on Performance Index was not significant (P>0,05).     Means of Performance Index were  27,5 (P0),  35,3 (P1),  37,5 (P2,)    37,7 (P3)  and 38,8 (P4).  The effect of supplementation of treatments on Income Over Feed and Chick Cost (IOFCC) was highly significant (P < 0,01). Means of  IOFCC were  Rp. 7192 (P0),  Rp. 12971 (P1),   Rp. 15673  (P2),  Rp. 13864 (P3) and  Rp. 14982 (P4).  In conclusion, effect of the addition of Acacia nilotica with/without fermention on super native chiken  Performance Index was not significant.  The effect of treatments on Income Over Feed and Chick Cost was highly significant.   There is  relationship between Performance Index and Income Over Feed and Chick  Cost.  Where treatment in low  Performance Index,  an also is lowproduce in Income Over Feed and Chick  Cost.

Abstract

This is a qualitative study, the results of the observations presented descriptively. The Problem of this study was how these types of questions cognitive teachers and students in physics learning process at class X SMA of Palu City, the purpose of this study was to describe and analyze the types of questions teacher and student, classify cognitive level teacher's and student?s questions in physics learning process at SMA of Palu City. Based on analysis in physics learning process 4 teachers researched, there are 56 questions consisting from 44 questions by teacher and 12 questions submitted by students. Teacher A submitte 14 questions consisting of 6 remembering question, 4 understanding questions, 2 application questions, and 2  analysis questions. Teachers B submitte 10 questions consist 5 remembering questions, 1 understanding questions, 3 aplication questions, and 1 analysis questions. Teacher C submitte 10 questions consist 4 remembering questions, 4 understanding questions, and 2 analysis questions. Teacher D submitte 10 questions consist 4 remembering questions, 2 understanding questions, 3 application questions, and 1 application questions. This result obtained that increase the ability of teacher?s asked in physics learning process still needed, whereas question submitted by student in physics learning process are 12 questions that consist 4 remembering questions, 3 understanding question, 4 application questions. The cause of less questions submitted by student in physics learning proses is the learning process still dominate by teacher. Related material the majority of questions that teacher gave is a low-level of cognitive questions that require short and certainly answers that require knowledge and understanding. These result identify that the increased teacher ask ability in process of physics learning still needed.

Abstract

The main problem on this research is the low activity and learning output on the year six students elementary school (SD) Inpres 1 Tondo. Therefore, based on this problem, classroom action research has been done. The aim of this research is to implement the cooperative learning model of group investigation type. The studying focused on the main material about less energy which taught on semester II based on the program at that school. The instrument which used was lesson plans, scenario of teaching, sheets of observation activity for student and teacher, and final test at the action of cycle 2. For the results of learning output on cognitive at the pre-action average score was 65,9 the classical understanding was 65,9 and the classical completed was 52,5%. On cycle I, the average learning output score was 68,7, the classical understanding was 65,9, and 65,9% of classical understanding. On cycle II, the average csore was 88,30, and the classical completed was 87,5%. In cycle I, affective score was average 3,2 (begin to develope), in cycle II, it was 3,55 (habit). Psychomotorscore was average 3,2 (begin to develop) in cycle I and it was 3,8 (habit) in cycle II. To achieve the criterion of classical completed was influenced by the optimum of teacher and student actifity during the learning process using group investigation.
