Towards batch-processing on cold storage devices
Large amounts of data in storage systems is cold, i.e., Written Once and Read Occasionally (WORO). The rapid growth of massive-scale archival and historical data increases the demand for petabyte-scale cheap storage for such cold data. A Cold Storage Device (CSD) is a disk-based storage system which is designed to trade off performance for cost and power efficiency. Inevitably, the design restrictions used in CSD's results in performance limitations. These limitations are not a concern for WORO workloads, however, the very low price/performance characteristics of CSDs makes them interesting for other applications, e.g., batch processes, too. Applications, however, can be very slow on CSD's if they do not take their characteristics into account. In this paper we design two strategies for data partitioning in CSDs -- a crucial operation in many batch analytics tasks like hash-join, near-duplicate detection, and data localization. We show that our strategies can efficiently use CSDs for batch processing of terabyte-scale data by accelerating data partitioning by 3.5x in our experiments

Environment Law and Natural Sustainability resources: case of Pawon Cave Area Conservation Gunung Masigit Village, Cipatat District, West Bandung
This study aims to examine the sustainability of the conservation of the Pawon Cave area and the factors that influence it. Sustainable development includes ecology, the region's social and economic benefits, and mining potential. The method used is a mixture of qualitative and quantitative. Herein, the community access to the Pawon Cave area is gardening, taking firewood, and taking grass. Processing and minimization of soil erosion are well managed, including a terracing system. Plants and animals in the area are maintained with no logging or hunting. The site provides benefits such as water, rice, vegetables, and fruits, as well as fertilizer for agriculture. Moreover, factors that affect the sustainability of the conservation of the Pawon Cave area are policy support from the government and having adequate human resources to manage the place. The implementation of the policy has shown that it is appropriate to support conservation efforts such as prevention of mining, preservation of springs, and protection of plants and animals in the area. Several construction facilities have also been built to support tourism. The coaching and training program for the caretaker of the Pawon Cave area is an effort to keep the area manager's human resources professionals. The incentives given by the government to the Provincial Jupel are 500,000/month, and the Regency Jupel is 450,000/month
Salicylic acid and methyl jasmonate enhance drought tolerance in chamomile plants
Introduction: The dried flowers of chamomile contain many terpenoids and flavonoids contributing to its medicinal properties. Salicylic acid (SA) and methyl jasmonate (MeJA) have antioxidant properties and function as direct radical scavengers. Two Matricaria chamomilla cultivars (Bodgold and Hungary breed seeds) were used in this study to investigate the effects of exogenous application of SA and MeJA on protection against drought stress as well as on changes of malone dialdehyde (MDA) and electrolyte leakage index (ELI), and the fluctuation of proline and soluble sugars content in the leaves under drought stress. Methods: The experiment was conducted in a factorial design based on randomized complete blocks with three replicates. Chamomile plants were treated by two levels of drought stress as well as two different levels of MeJA (i.e., 0.0 and 100 μM) and SA (i.e., 0.0 and 0.5 mM) solutions. Results: There was a dramatic drought induced increase in the MDA content (128) and ELI (49) in the leaves. Deleterious effect of drought stress was more severe in untreated plants than in treated ones. Treatments with SA and MeJA significantly improved drought tolerance in chamomile plants. These treatments effectively maintained membrane integrity, thereby retarding electrolyte leakage and membrane lipid peroxidation (MDA). Treatments with SA and MeJA were also effective in enhancing the antioxidant concentrations of proline and soluble sugars. Conclusion: The production of these antioxidants could have been part of a defence system against drought damage, reducing MDA and ELI and maintaining membrane stability.</p

SOCIAL IMPACT OF MANGROVE LAND CONVERSION IN DIMENSIONS AS RURAL SUSTAINABILITY
Mangrove ecosystem is an important part of the coastal environment. One of the problems in almost all coastal areas in Indonesia is the degradation of mangrove area. In the coastal areas of Langkat Regency, precisely in the Tapak Kuda Village is also facing the same thing. In the last 15 years, mangrove area has reduced quite high. One of them is caused by the conversion of mangrove land into ponds. The existence of mangrove ecosystems is related to socio-economic life of society that causes the decline of mangrove area and the changing environmental conditions of social life. The results showed that the conversion of mangrove land brought the social impact on residents’ lives. Changes in the types of jobs are fishermen decreased 24%, the percentage of farmers rose 19% and fish farmers also rose 10%. Income-related conditions, 24% of people feel steady and have sufficient income to meet the families’ needs, 43% of people feel sometimes high income is not enough to meet families’ needs and 33% of people feel low income that make the families’ needs are not fulfilled. The condition of public education level has increased, the percentage of people completing primary school rose 7%, junior high was up 21%, and high school 16%. Regarding the use of natural resources, there were only 35% of the natural resources that could be managed by the community. Community land use patterns are 10% of ponds, 30% of fields, 20% of fishing areas and 40% of conservation areas
