Abstract

The use of antibiotics as an Antimicrobial Growth Promoter (AGP) for livestock has been banned because antibiotic residues in livestock meat can trigger antibiotic resistance in consumers. Propolis is a natural source that has benefits like antioxidants, antiviral, antifungal, and antibiotic. The purpose of this study was to determine the effectiveness of the addition of feed from the optimal composition of raw propolis to increasing broiler chickens' body weight of broiler chickens. This study used broiler chickens as experimental animals. The chicken were grouped into six groups consisting of two control groups and four treatment groups with different level concentrations of propolis (2, 4, 6, and 8 g/kg feed). After treatment for four weeks, supplementation of raw propolis in the feed had not been able to provide a positive effect on growth performance and protein levels that were not significantly different from controls. Group chickens with propolis additions 6 g/kg feed showed the best results compared to other treatment groups. The group had final weight values, food conversion ratio (FCR), and carcass weight in 1970.67 gram, 1.52, and 1349.83 gram, respectively. The highest percentage of the carcass was shown by group chicken with propolis additions 2 g/kg feed, which is equal to 74.46%. Raw propolis can reduce feed consumption but increase feed conversion ratio.

Abstract

This research is a Classroom Action Research which aims to determine how efforts to improve learning outcomes through the model of Contextual Teaching Learning students 5B grade in science subjects at SDN Siliwangi. The grand tour initial showed that only 35.71% or 15 students scored above the KKM with a total of 42 students. The average science score in class 5B is 60.95. This Classroom Action Research uses the Kemmis and McTaggart model which consists of planning, implementing, observing and reflecting with success indicators of 80% of students have achieved learning outcomes with a KKM score of 65 and teacher and student activeness reaching 85%. The results showed that from 3 aspects studied, namely: Student learning outcomes obtained 54.76% learning completeness in the first cycle and 76.42% in the second cycle 84.37% student activity in the first cycle and 87.50% in the second cycle. Teacher activeness was 83.34% in the first cycle and 89.58% in the second cycle The increase in the percentage of the results of the primary cycle aspects of student learning outcomes was 19.05%, 22% student and activeness13% teacher activeness. Meanwhile, in the first cycle and the second cycle, the increase in the aspects of learning outcomes was 28%, student activity 3% and teacher activity 6%.

Abstract

Utilization of technology in education will produce good quality learning, up to date, make critical thinking, have conceptual thinking and easy to access various learning resources. Together with technology, the teacher must realize a learning assisted learning media, so that students’ interest in learning increases. Articulate storyline application is an interactive multimedia application that can be used by teachers or students. Based on observations found that teachers use media objects for learning in class, especially in force material, then based on the results of interviews with teachers, teachers more often use learning media types of objects, visuals and silently projected. The purpose of this study is to validate the articulate storyline as a learning medium on force material. The steps of this research development include initial research and information gathering, planning, developing initial product formats, initial trials and product revisions. Data collected through observation, interviews and questionnaires. The results of the validation of the material experts stated that media is valid with an average value of 79.65%. Furthermore, the results of the validation of the media experts stated that media is valid with an average value of 86.16%. In tested valid media products with an average of 81.93%. From the results of these data the researchers concluded that the articulate storyline-based media are valid, and suitable for use as learning media.

Abstract

Red shrimp paste is one of the consumers' attractions. Usually, shrimp paste uses textile dyes. The purpose of this study is to obtain a natural red pigment that is safe when applied to food products. The method used is the addition of Caesalpinia sappan extract 0.01% (w/w) and 0.02% (w/w) when compared with the control. Test parameters include water content, salt content, protein content, acid insoluble ash content, pH, hedonic organoleptic test. The results showed that the addition of Caesalpinia sappan extracts significantly affected water content (21.94% -28.06%), salinity (7.05% -6.55%), ash content (0.45% -0.48 %) and pH (6.99-6.40). The hedonic test results obtained that the preferred shrimp paste is by adding 0.02% (w/w) of Caesalpinia sappan extract with ºhue 50.11 (shrimp paste has red colour).

Abstract

Coffee commodity is one of the commodities that is the main target of the priority sub-agenda for agro-industry improvement. Indonesia is the fourth largest producer in the world and makes coffee one of the leading plantation commodities. Robusta coffee in Babakan Madang District is one of the coffees that has the potential to be developed because it is a specialty type of coffee that has a distinctive taste and has a wide-open market. However, inadequate marketing due to low prices at the farm level is one of the problems for Robusta coffee in Babakan Madang District. This study aims to analyze the structure, conduct, performance of Robusta coffee in Babakan Madang District, Bogor Regency. Data were analyzed qualitatively and quantitatively using the approach structure, conduct, performance (SCP). The result of this research is there are 6 established marketing channels, with channel II having the largest sales volume. Analysis of the market structure formed for the marketing of Robusta coffee is monopolistic competition at the farmer level. The level of village collector traders is oligopoly, large trader 1 and large trader 2 monopoly. The Robusta coffee market is very highly concentrated. Barriers to market entry are high for new competitors. In market behavior, the marketing functions performed by each marketing agency are exchange, physical, and facility functions. The price determination at the farm level is carried out by the marketing agency, then at the merchant level the price is determined by themselves. In market performance, the margin value and farmer's share efficient are obtained from channel VI, because on this channel the smallest margin value and they are obtained farmer share largest.
