: The high data speed generated by sensor devices has led to an awareness of the potential impact of big data analytics (BDA) and the Internet of Things (IoT). This paper highlights 4 types of moral holistic values for BDA analyzer, system developer, data provider and user in integrating the BDA and IoT applications. Being ethical is about confronting ethical issues. Wisdom, glory morality, courage, and justice are important holistic values for handling data sharing, data collaboration and data analytics. Four moral holistic values will reduce the gap between IoT, human and practice to improve the performance and revolutionize the performance of BDA and IoT-based applications.

: Concentric loading on the Nailed-slab Pavement System causes stress in the soil and the inner forces in structural elements. The load stress is transferred to the soil by the structural elements tends to concentrate in the centerline area under the system. Since load stress is concentrated in the center line area, the soil stress and inner forces can be higher in the center of the system. To reduce the soil stress and inner forces of structural elements, the longer pile can be put in the center area of the system. This research is aimed to learn the soil stress and inner forces behavior of the Nailed-slab Pavement System in case putting the longer pile in the center area of the system. The maximum double wheel load was taken 50 kN which transfer to the slab surface by contact pressure. Wheel load was loaded in the center of the slab. The Nailed-slab materials properties and soft clay properties were taken from the previous researcher. The piles in the center area of the Nailed-slab were longer 33.3% than others. Results show that the Nailed-slab by longer piles in the center area can reduce the soil stress significantly for maximum shear stress up to 28%. The inner forces were also reduced by about 43% to 46% and caused the reducing in lateral deflection of pile tip about 37%. It can be concluded that the increasing pile length in the central area of the system can reduce soil stress and inner forces of the system.

: One of the large private universities (PTS) in Riau Province is known as Universitas Islam Riau (UIR). UIR is a large university and has extensive land infrastructure that is planted with a variety of green plants such as trees and flowers. These trees have encountered many problems, namely producing leaf litter and causing problems. Lots of leaf litter is collected and disposed of at the final disposal site. Some can be processed into compost manually and some are burned. In the composting process, the processing time is too long, so it is necessary to design a construction machine for crushing dry leaves. This machine consists of an inlet and outlet, a tube made of drums, a five-level shredder and with an electric motor. From the results of the design of the construction size length 60 cm width 60 cm and height 100 cm made of angle iron L profile size 40 x 40 x 4 cm with a power of 12 HP and 1400 rpm motor drive rotation.

Crude oil is a chemical compound of saturated paraffin wax, aromatics, napthane, asphaltic, and resins indeed this material produce wax deposits. Deposition of paraffin has potential to harmful the production due to the existence of blockages, whether partial or the whole of the pipeline. Various techniques have been developed to overcome this problem; one of them is the use of solvents from agriculture waste. Incidentally, the materials are easy to obtained and economical. Based on the Central Bureau of Statistics data, the agricultural waste in Indonesia recorded 5,883,730 tons/year for corn waste, 439,657 tons/year for pineapple skin waste, and 15.8 tons/year for rice husk waste. The potential of agricultural waste can be used as a source of raw materials for manufacturing solvents by using bioethanol by ways of pretreatment, hydrolysis, fermentation, and distillation process. In addition, the result of several past studies shows that bioethanol made from pineapple skin produce 8% of ethanol; bioethanol from corncobs produce 19-22% of ethanol; and bioethanol from rice husk produce 14.4227% of ethanol. Therefore, it means that agricultural waste can be used as a source of bioethanol in manufacture of solvent and could overcome the problem of paraffin wax.

: The login system is a process for accessing a computer by entering the identity of the user and the password to obtain permissions using the destination computer resources. In an information system security issues and maintaining data confidentiality is one important aspect. However, these security issues often get less attention from the owners and managers of information systems. If talking about security issues related to the use of computers, it is difficult to separate it with the login process. Login aims to provide security services on the system. In this research used ElGamal cryptography algorithm to secure username and password in web login. The security level of this algorithm is based on the problem of discrete logarithms in the multiplication group of prime modulo primes. This algorithm includes asymmetric cryptography algorithms that use two key types, namely public key and secret key. The data contained in the login is secured by using ElGamal algorithm, so the username and password entered into the database are already in the form of ciphertext.

: Importance of Carbon Dioxide (CO 2 ) injection into the subsurface reservoir is essential since the concern of global warming and climate change issues in Indonesia. Selecting the oil reservoir as a candidate for a storage site is an attractive option due to CO 2 gas utilization is effective for Enhanced Oil Recovery (EOR) purpose. Continuous and Water-Alternating-Gas (WAG) CO 2 flooding are the most commonly applied scenarios in the oil and gas industries. Considering the EOR side, choosing an appropriate scenario is mandatory for cost efficiency reason and influences the oil share amount between the Indonesian Government and operator under the gross-split mechanism. Therefore, by using a simulation approach, the feasibility of continuous and WAG CO 2 injection is observed to decide the most financially attractive choice. Simulation results reveal a WAG scenario recovers slightly more oil compare to continuous injection scheme. Application of gross-split under base-share makes both injection strategies unattractive for investors. An adjustment of government-contractor share is required to improve the feasibility of the project.
由于印尼关注全球变暖和气候变化问题，向地下水库注入二氧化碳(CO 2)的重要性至关重要。选择储层作为备选储层是一个很有吸引力的选择，因为利用二氧化碳气体可以有效地提高石油采收率(EOR)。连续和水-气交替(WAG) CO 2驱油是石油和天然气工业中最常见的应用场景。考虑到提高采收率方面，出于成本效益的考虑，选择合适的方案是强制性的，并且会影响到印尼政府和运营商在总分成机制下的石油份额。因此，通过模拟方法，观察了连续和WAG CO 2注入的可行性，以确定最具经济吸引力的选择。模拟结果显示，与连续注入方案相比，WAG方案的采收率略高。基股下的总分割使得这两种注入策略对投资者都没有吸引力。需要调整政府-承包商的份额，以提高项目的可行性。

: FWk-NN is an improvement of k-NN, where FWk-NN gives weight to each data feature thereby reducing the influence of features that are less relevant to the target. Feature weighting is proven to be able to improve the accuracy of k-NN. However, the FWK-NN still uses the majority vote system for class determination to new data. Whereby the majority vote system is considered to have several weaknesses, it ignores the similarity between data and the possibility of a double majority class. To overcome the issue of vote majority at FWk-NN, the research will change the voting majority by using distance weight. This study uses a dataset obtained from the UCI repository and a water quality data set. The data used from the UCI repository are iris, ionosphere, hayes-Roth, and glass. Based on the tests carried out using UCI repository dataset it is proven that FWk-NN using distance weight has averaged an increase about2%, with the highest increase of accuracy of 4.23% in the glass dataset. In water quality data, FWk-NN using distance weight can achieve an accuracy of 92.58% or has increased 2% from FWk-NN. From all the data tested, it is proven that the distance weight is able to increase the accuracy of the FWk-NN with an average increase about 1.9%.

: An experiment about the effect of three stocking densities (10, 30 and 50 larvae L -1 ) on growth and survival of the selais fish larvae, an important commercial species, and the source of income for the rural community was conducted at the Fish Hatchery of the Agriculture Faculty, Universitas Islam Riau, Indonesia. Three-day post-hatched larvae (0.0012 ± 0.00 g in weight ; and 0.03 ± 0.00 cm in length) were used as test fish that obtained from the artificial spawning of the selais fish broods. The fish larvae reared in recirculation system with a water flow rate of 0.05 L -1 , and fed with silkworms ( Tubifex sp ).This study used a completely randomized, non-factor design with three treatments and three replications. The best growth in weight and growth in length (of 0.87 ± 0.00 grams and 5.39 ± 0.49 cm, respectively) were found in the T1 (stocking density was 10 larvae L -1 ). The highest survival rate (57.33 ± 7.72) was attained in T1 (stocking density was 10 larvae L -1 ) while the lowest survival (51.60%) attained in T3 (stocking density was 50 larvae L -1 ) . Growth rate and survival rate of the selais fish larvae were inversely proportional to the density of the fish larvae.There’s no significant effect of stocking density on the growth and survival of the selais fish larva (P > 0.05).
