Complementary foods must fulfill the criteria for nutritional needs that have been regulated by the government such as adequacy of macro and micro nutrients. One of the local food ingredients that can be used as complementary foods is pumpkin.Pumpkin is known to contain nutritional components that are quite complete but have a small protein content. Therefore, it is necessary to add nuts as a source of protein. The purpose of this study was to determine the comparison effect of pumpkin puree with various types of nuts on the proximate composition and organoleptic properties of complementary foods. This study used a completely randomized design with one factor, namely the differences in the type of bean puree with five levels of treatments, A1 (35% pumpkin: 35% Bambara bean), A2 (35% pumpkin: 35% kidney bean), A3 (35% pumpkin: 35% mung bean), A4 (35% pumpkin: 35% soybean), and A5 (35% pumpkin: 35% edamame bean). Data analysis using analysis of variance and Kruskall Wallis test. The result showed that the Complementary Foods formulations made with 35% pumpkin puree and 35% soybean puree had the highest nutritional content. The Complementary Foods had 57.25% water content, 2.83% ash content, 20.62% protein content, and 10.49 fat content which had fulfill the Complementary Foods standard except the carbohydrate content.

The problem of poor drainage can be the cause of a local flood, as happened in Bogor City, West Java. Development evaluation related to local flooding in a city is an exciting topic to study further. The purpose of this evaluation is to answer the need for public information about the philosophy of flooding in the highlands, existing policies, and factors causing local flooding in Bogor City. The benefits of this analysis can also provide policymakers with input on strategic steps in the planning of urban drainage infrastructure systems, both in terms of physical channels, social approaches, and aspects of land carrying capacity within the ecological framework. The method used in this evaluation is in the form of literature studies and direct field observations of Bogor City's drainage infrastructure at specific points. The recommendation for the Bogor City government is to carry out comprehensive data collection and re-topography, namely by collecting data on buildings and drainage, determining the slope and height of the channel, and implementing risk management at each stage of its implementation. In addition, strict supervision and community participation in overseeing the development process and reducing waste disposal in the river supports the improvement of drainage development.","PeriodicalId":381629,"journal":{"name":"Indonesian Journal of Applied Research (IJAR)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127624958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Quail eggs have nutritional value that is not inferior to other poultry eggs. Feed is one of the factors that can affect egg quality. Coriander is a spice that contains essential oils that are beneficial for the body when consumed. So it is hoped that the presence of this essential oil can help improve livestock growth and produce quality quail eggs sensory. This study aimed to examine the effect of giving coriander flour to quail feed on the sensory quality of eggs. The study was conducted for 30 days. The livestock used were Japanese quail aged 30 days with 100 heads. The feed used is commercial feed and additional coriander flour. The design used was a completely randomized design with 4 treatments and 5 replications for each unit of 5 birds with treatment R0 = commercial feed +0% coriander flour, R1 = commercial feed + 0.5% coriander flour, R2 = commercial feed + 1% coriander flour, R3 = commercial feed + 1.5% coriander flour. Data were analyzed using Kruskall Wallis and Duncan's multiple range test. The results showed that the administration of coriander flour had a significant effect (P<0.05) on the hedonic test of egg white color and texture hedonic quality test, while for the egg yolk color, taste, aroma variables were not significantly different (P>0.05). This study concludes that organoleptic administration of 1% coriander flour can increase the panelists' preference for egg whites and improve the texture of quail eggs.","PeriodicalId":381629,"journal":{"name":"Indonesian Journal of Applied Research (IJAR)","volume":"224 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131847974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper has shown that the protection of natural ecosystems has a better impact than infrastructure development, especially about preventing inundation due to high surface runoff. This journal will strengthen the need for watershed-scale erosion prediction analysis because of its ability to define strategic areas of policy intervention to enable policymakers and the community to carry out recovery programs/activities more effectively and focused. The accuracy of determining the location of the policy has an impact on cost, time, and energy efficiency. Spatial calculation/analysis models combined with social and economic approaches will create a balanced and integrated sustainable development.
