THE RELATIONSHIP BETWEEN LINGUISTIC INTELLIGENCE AND STUDENTS’ COGNITIVE ABILITIES IN THE SUB-CONCEPTS OF DISASTER RESPONSE ACTIONS
Full text linkThis research is a correlational study that develops quantitative descriptive research. This study aims to obtain information about the relationship between linguistic intelligence and cognitive abilities in the sub-concepts of disaster response actions and other factors that influence it besides linguistic intelligence. This research was conducted in September 2019. The population of this study was MTS Darul Irfan students of Serang City in the academic year 2019/2020. The sampling technique uses simple random sampling. The sample was 24 students of class VII-A. The data collection method is done by tests, documentation, student worksheets, and observations. Based on the regression and linearity test results, it can be concluded that the simple regression analysis with the equation Y=37.986+0.038X is linear. Based on the result of quantitative research, the correlation coefficient between linguistic intelligence and cognitive abilities is 0,0030. This correlation coefficient value indicates that H0is rejected and H1is accepted, meaning linguistic intelligence weakens student cognitive abilities. In this study, other factors affect student cognitive abilities, among others, strategies and learning methods, development of learning media in schools, and environmental factor of students

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Partnership to Create a Food Independent Urban Village in Tanjung Mas, Semarang City
Full text linkTanjung Mas Village, North Semarang District is one of the areas in Semarang City that is vulnerable to food insecurity. This food insecurity is caused by the high level of poverty in this region. Poverty has a big impact on food security because poor people are unable to provide sufficient amounts of food, either by producing it themselves or by buying it. This condition encourages the government and society to start trying to fulfill their food needs independently through farming. However, these efforts are hampered by limited agricultural land availability. The aim of the community service program is to provide knowledge, skills and facilitate urban farming facilities to achieve food independence in the Tanjung Mas, Semarang City. The methods used are socialization, counseling, dissemination, training and facilitation of urban farming facilities. The results of this community service program are that the community has an understanding of urban farming, knows the technologies in urban farming, has verticulture skills, and verticulture facilities are available as learning demonstration plots
PEMANFAATAN MIKROORGANISME LOKAL UNTUK PENGELOLAAN SAMPAH ORGANIK DI DESA SEKARAN
Full text linkThe village of Sekaran is one of the villages located close to the UNNES Campus. The cur- rent Village of Sekaran villagers are in addition to the natives, UNNES students who rent houses or boarding in the area, and some are urban, or urban, people who prefer suburban residences. Some of the land in the village of Sekaran has turned into housing and one of the closest housing of the cam- pus is Sekar Gading Housing. Residents in Housing Sekar Gading, especially the mothers belonging to Dasa Wisma are very hungry for various activities based on environmentally friendly. One of the activities they want is how to make organic fertilizer especially from household waste. Therefore, the initial plan of activities originally in the village of Banyuwindu devotees move to the village of Sek- aran, especially in Housing Sekar Gading. The main reason for moving the location because after coordination several times Banyuwindu community difficult to determine the time of activity, while the implementation time of service activities should be as soon as possible. While the choice of loca- tion in Housing Sekar Gading because of the welcome and enthusiasm of people in the housing is very good. Targets to be achieved in this activity is the increasing understanding of the community in Housing Sekar Gading in managing waste independently, the community is able to utilize local mi- croorganisms as an environmentally friendly composting material, and can reduce the dependence on the use of chemical fertilizers. The outcomes of this devotional activity are 1) articles for national seminars or journals, 2) appropriate technology (TTG) of local potential waste-based waste manage- ment. The results achieved in this activity is organic fertilizer products using local microorganisms
Diversity and Conservation Knowledge of Chondrichthyans in Northern Coastal Areas of Central Java
Full text linkNorthern coastal areas of Central Java potentially produces sharks and rays (Chondrichthyes) for dishes. However, lack of community understanding of protected species catchment affects the Chondrichthyans conservation management. This study aimed to identify of total Chondrichthyans that were captured by fisherman correlated to the conservation knowledge and action in northern coastal areas of Central Java. This research was conducted by using interview, and direct observation. Samples were collected in fish capture household places in Tegal, Pemalang, Pekalongan, Semarang, Pati, and identified in Animal Taxonomy Laboratory of Biology Department, Universitas Negeri Semarang. Data were analyzed using descriptive qualitative based on the morphology characteristic. This research found that every season, at least 1,106 individuals from 23 species of Rajiformis and Lamniformis (Chondrichthyes) orders was captured. This condition was aggravated with lack of access to information and low fisherman’ awareness of protected species. It was also found that shark and ray trading generates value chain in culinary business. It increases fish consumption demand that only can be provided by fish catchment from the ocean. The implication of species catchment is declining population of Chondrichthyes in Central Java north areas. Based on the research, a high demand and lack of access to information correlated with declining community awareness on conservation actions. this research adds more information as an effort to conserve shark and ray species based on problems faced by fishermen. The information is also able to be applied as a foundation to develop community based conservation action
