Feed is an important factor that influences the chicken's development and growth. Meanwhile, dalugha debris is a by-product of dalugha processing which is expected to be a source of feed for the growth and development of broiler chickens. The good feed can optimize metabolic processes in the animal so that it can support the process of growth and development of the animal. This study aims to determine the levels of hemoglobin, cholesterol, and blood glucose in broiler chicken that is given dalugha debris supplementation. This study used a completely randomized design (CRD), where as many as 60 docs of unsex chicken used were divided into four treatments and three replications. Each replication consisted of five chickens. The treatment given was the concentration of dalugha debris at several doses: 0%, 0.065%, 0.13%, and 0.26%. The parameters observed were hemoglobin, cholesterol, and blood glucose levels. The results showed that the provision of dalugha debris in the feed significantly (p<0.05) affected the blood glucose level, but did not affect the cholesterol and hemoglobin levels (p>0.05) of the broiler chicken.

The teacher resources development becomes a central issue in public discussion. The plan, implementation, monitoring and evaluation of teacher resource development in Dinas Pendidikan Manado is being provoked and receives attention. The provoking issues play around on how teacher resouces development being planned, implemented, and evaluated. This study takes a qualitative approach and utilizes a case study method. In-depth interviews are the primary data collecting tools, followed by document study techniques/literature and observation. However, monitoring and evaluation success requires adequate implementation quality, appropriate monitoring and evaluation standards, and a special monitoring and evaluation budget. In conclusion, the government should inform and promote the pattern of execution of teacher resource development. That is, more attention and a dedicated budget for the creation of teaching resources are required. The pattern of teacher resource development monitoring and assessment is based on both internal and external stakeholders. The government must state and report the pattern of implementation of teacher resource development. This means that more attention and special budget are needed to create teaching resources. The pattern of monitoring and assessment of teacher resource development is based on internal and external interests. As a result, by using explicit and redundant standards, supervisor quality becomes an important predictor of successful monitoring and assessment.

The utilization of pineapple peel in the fermentation process produces bacteria and probiotics that are beneficial for human health. The fermentation process is carried out to enhance the nutrition, shelf life, and organoleptic properties of food products. The presence of microbes, especially bacteria, is believed to play an important role in the fermentation process of pineapple peel. However, the specific bacteria involved in the fermentation of pineapple peel are not yet fully known. The aim of this research is to study the bacterial succession during the fermentation of pineapple peel (Ananas comosus (L.) Merr) and to identify the types of bacteria obtained during the fermentation process. This research uses a qualitative descriptive laboratory-based method by conducting morphological identification of bacteria and biochemical testing to determine the types of bacteria present in the fermentation of pineapple peel. Based on the identification data, 11 bacterial isolates were found during the fermentation of pineapple peel. The isolates were identified macroscopically and then subjected to a series of biochemical tests. The results of the research indicate that the microorganisms involved in the fermentation of pineapple peel belong to the genera Staphylococcus sp., Bacillus sp., and Lactobacillus sp.. The microbial succession during pineapple peel fermentation shows that the bacterial population of the genus Staphylococcus sp. dominates on day 0 of fermentation, while the genus Bacillus sp. undergoes a succession pattern, experiencing growth on day 1 and continuing to increase until day 3. Meanwhile, bacteria from the genus Lactobacillus sp. only appeared on day 1 of fermentation.
