DBSCAN algorithm (Density-Based Spatial Clustering of Applications with Noise) is one of the numerical based clustering algorithms, numerical data is used as the test for this algorithm. The DBSCAN algorithm has the disadvantage of being difficult to determine the appropriate Epsilon value in order to obtain good clustering results. In the DBSCAN algorithm, the value of epsilon is calculated based on a lot of data from the entire data that is captured. In this study a modification of the DBSCAN (Density -Based Spatial Clustering of Applications with Noise) algorithm was carried out by determining the value of epsilon, the results obtained in the study of Euclidean Distance obtained better than the results obtained from the DBSCAN.
DBSCAN算法(Density-Based Spatial Clustering of Applications with Noise)是一种基于数值的聚类算法，用数值数据作为该算法的测试。DBSCAN算法的缺点是难以确定合适的Epsilon值以获得良好的聚类结果。在DBSCAN算法中，epsilon的值是根据捕获的整个数据中的大量数据计算的。本文通过确定epsilon的值，对DBSCAN (Density -Based Spatial Clustering of Applications with Noise)算法进行了改进，得到了比DBSCAN更好的欧氏距离研究结果。

Coffee plants (Coffea sp.) are C3 plant groups, with characteristic of low photosynthetic efficiency, which is due to the occurance of photorespiration. In simple agroforestry systems, legumesare commonly used as shade trees. In addition, pruning and fertilizing are also very important cultivation techniques incoffee plantation business. This study was aimed toto obtain the maximum potential of coffee production at a certain height in Humbahas Regency with a package treatment of pruning, fertilizing and shade technology. Plant experiments were carried out at an altitude zone of 1200-1300 meters above sea level(masl) which was designed in the form of Splits plot design. There are three factors tested, the main plot is shade with a levelof without shade (N0) and shade (N1); the main subplots are pruning, namely pruning with the farmer system (P1) and pruning recommendations (P2); while thesubplots are fertilization methods consisting of: farmers' fertilizing level (O0), giving organic fertilizer from coffee pulp at a level of 10 kg / tree (O1), giving organic fertilizer from manure at a level of 10 kg / tree (O2), giving phosphate fertilizer (SP36) 150 g/ tree. The growth and production of coffee plants are influenced by the interaction between shade plants, pruning and fertilization. On all altitudes level in this experiment, vegetative growth in plants were improvedin not shaded by pruning conditionsand application oforganic fertilizer, both with manure and coffee pulp compost. However, the best yield production was obtained at under shaded conditions in which the plants were cut according to theprune recommendations.

Study about Corporate Social Responsibility (CSR) is still have a limitation in CSR because of the slight findings of research to CSR and disappointing industrial social presentation. Executing CSR programs may be a way to serve to clients that are responsive to sustainable application. In years, there has been a range in thought about to improve the social and organizations’ environmental or sustainability performance. Sustainability has become increasingly significant to study of business and the application over past decades as a result of quick dilution of natural origins and interests over responsibility. The review of CSR research moves to a relational perspective for coordination, communication, and collaboration within those stakeholders. Consider the complexity of Stakeholder Environment in the construction industry, an agenda of research that integrates the management’s interest and planning theory for future CSR research.

: There are still many people in the banks of the river in the city of Medan, especially in the Deli river, which uses river water for their daily needs. This study was conducted to reduce the water turbidity of the Deli River by using a ceramic membrane made from clay. The ceramic membrane was made by analyzing the effect of the composition and the size of the additional ingredients of rice husks and sawdust to the reduction of water turbidity in the Deli River. This ceramic membrane is made in the form of a pot (pot filter) with the height of 18 cm and the diameter of 21 cm which is burned at the temperature of 850 o C - 900 o C for 8 hours.Variations in the size of the material used are range from 35-50, 50-60 and 60-100 mesh with a comparison of the composition of materials (80%: 20%), (85%: 15%) and ( 90%: 10%). The result of the research on clay ceramic membranes with the additional turbidity reduction efficiency is equal to 90.36%. Whereas, clay ceramic membranes with the addition of rice husk showed a decrease in turbidity with an efficiency of 88.76%.

Drought stress is a major problem in crop production worldwide. The unavailability of groundwater and erratic climate change causes a lack of water for plants. Efforts that can be made to maintain sweet potato production in drought conditions are by planting genotypes that are tolerant of drought stress. This research aim was to determine the growth and production and also to analyze the physiological characters of several sweet potatoes genotypes on various watering level. The observed parameters were chlorophyll a, b and total and also relative water content at two months and three months after planting (MAP). The results showed that sweet potato genotypes had a different response to the level of watering. The response of each sweet potato genotype was significantly different in the parameters of chlorophyll a, b and total chlorophyll in the third month and the relative water content at 2 MAP. The Binjai accession genotype had the highest chlorophyll a, b and total chlorophyll content compared to other genotypes at 3 MAP. Watering levels treatment significantly affected the chlorophyll a, b and total at 3 MAP. The optimum watering significantly increases the chlorophyll a, b and total chlorophyll content at 3 MAP.

: The environmental degradation in the Lake Toba Water Catchment is multidimensional, so the recovery effort requires a holistic and integrative approach. Based on its multifunction, agroforestry system has potential for ecological regulation as well as community economic development through bee cultivation. This study aims to illustrate the potential of apiculture practices in agroforestry system in Lake Toba. The research was conducted on coffee-styrax-agroforestry system integrated with Apis and Trigona beekeeping in Aek Nauli, Simalungun, Humbang Hasundutan and Pakpak Bharat, North Sumatra. Results showed that plant diversity in agroforestry system provides feed sources in form of nectar and resin for Apis and Trigona bees. Each Trigona colony produces 30-70 g propolis every two weeks which typical flavor of Styrax incense. Whereas from Apis bee cultivation obtained an average 0.3 liters of honey each stup at two weekly harvest. From this integrated practice, farmers earn income Rp1,2 to 2,4 million per month, the welfare improvement considering bee maintenance is relatively easy and minimal time allocation. The laying of bee colonies around coffee gardens also increase fruit production by flowering intensify. Beekeeping in the agroforestry system opens opportunities for alternative livelihood development, optimization land productivity, as well as increased public nutritional security.

Information about canopy density is needed in many ways, for example, in estimating forest degradation and forest quality. Utilization of vegetation index values on satellite imagery can be used to predict canopy density distribution. This study aims to predict canopy density distribution in mangrove forests. The methodology used is using regression analysis by connecting Normalized Difference Vegetation Index (NDVI) value with canopy density values in the field. The NDVI value is derived from Landsat 8 satellite images, while the canopy density percentage is obtained by using a camera. The spatial distribution of canopy density is obtained through spatial modeling using Geographic Information System (GIS). The results showed that the NDVI value of the linear regression model could be used to predict the density distribution of mangrove forest canopy with r square value of 59.0% and sig value <0.005.
