Abstract

ABSTRACT- Water is an absolute necessity that must be met, both for drinking water and for irrigation. An alternative to meet the water needs other than rainwater or surface water, is by taking underground water by drilling deep wells. Sembiran Village is a village located in Tejakula District, Buleleng Regency, the village is a dry area that requires water, both for drinking water and for agriculture. Location of groundwater drilling including Tejakula groundwater basin. In order to achieve the above objectives, an effective and efficient groundwater drilling technique should be carried out considering that the area geologically has rocks dominated by volcanic lava rock which are the products of Mount Agung and Mount Buyan Beratan Purba. The method of drilling groundwater is carried out in stages starting from drilling a Pilot Hole with a diameter of 6 to 64 meters, followed by an enlargement of 8 ", 10" to 12 "drill holes to a depth of 64 meters. In the field of drilling work the Hydrolic Rotary System Method, Direct Circulation Rotary Drilling is used and for the removal of cutting / dirt mud Fludia is used. The equipment used for drilling is rotary / skid mounted drilling machines with a capacity of up to ± 150.0-200.0 meters, equipped with equipment such as: mud pumps, a series of equipment that cannot be separated from one another. For well logging an Electrical logger is used for geophysical wellbore investigations. For the work of washing wells using compressor and other supporting equipment. Pumping the test uses a submersible pump that has a minimum discharge capability of 10 lt / sec and a maximum of 20 lt / sec. The results of direct observations and measurements of the physical parameters of the Sembiran Village Drilling Well (SEM-5) contain TDS = 219.; PH = 7.0. Chemically, Iron (Fe) = 0.001 mg/ltr; Arsenic (Ar) = 0.067 mg/ltr; Availability (CACO3) = 56.4 mg/ltr; Chloride (Cl-) = 91.6 mg/ltr; Nitrate (N) = 0.013 mg/ltr; Sulfate (SiO4) = 1.88 mg); Lead (Pb) = 0 mg/ltr; organic matter (KMnO4) = 0.34 mg/ltr, so the Drilling wells (SEM-5) meet clean water quality standards based on the Regulation of the Minister of Health of the Republic of Indonesia Number 492 / Menkes / Per / IV / 2010. Discharge obtained from pumping test results at SEM-5 wells is 20.47 liters/sec with surface water level(swl) = 23.60 m, and the position of the pump is placed at 42 m from the ground surface.

Abstract

This research needed a priori algorithm method to produce association rules, with a "if-then" pattern. Apriori algorithm uses an iterative approach known as level-wise search, where k-groups of products are used to explore (k + 1) product groups or (k + 1) -itemset (Han and Kamber, 2001). A priori algorithm method is expected to provide vacancy information on one of the stock items that are often purchased simultaneously by the customer. Product optimization is carried out using the profset model, which evaluates the profit margins generated per product and is developed to maximize cross-selling opportunities. Based on this background, research will be conducted under the title Shopping Cart Analysis in Retail Companies Using the Apriori Algorithm Method and Model Profset

Abstract

Architectural researchers have conducted researches on the architectural orientation of vernacular settlements, both explicitly and implicitly. The study results differ based on the understanding of the resident's culture of the community, their beliefs, and the context of their settlements. They understand that vernacular settlement architectural orientation results in a different orientation direction in one territory from another in Indonesia. Indonesia is an archipelago country with various tribes spread throughout the Indonesian archipelago. Each ethnic group has a different culture of living, so that the orientation of the Settlement as a form of relationship between tribal people and their "priority" is also different. The complexity of vernacular payments in Indonesia is fascinating to trace the grand conception through inductive studies. This study aimed to examine the conceptual orientation of the elaborate architectural direction of vernacular settlements in Indonesia using the literature method through the hermeneutic approach. The object of the study is the publication of research results in the form of journals and proceedings. The research results are (1) the conception of symbolic analogy, which means expressing an identity of immanent and transcendental relationships between people in a vernacular architectural territory with their "priority"; and (2) logical conception, understanding the existence of a place of residence as a necessity of life.

Abstract

Garuda was known in prehistoric India, where his paintings were found in the Harappa (Sindhu River valley), then spread to all corners of the world affected by Indian civilization. Its head, beak and claws are eagles, the light of the gods shining from its body. While Wilmana as a picture of a space vehicle that moves beyond the speed of thought. Wilmana is also a worldwide character, presented in the world of the internet, film and games. Padmasana architecture is a sacred building as a place/position of God, on the back is often carved by the two kinds of decoration. This research about ornamental variety is research in the context of traditional architecture, as an exploration of building concepts that have been developed in the past and are useful to apply to contemporary architecture. This study aims to re-express the meaning of Garuda and Wilmana and how they are placed on Padmasana architecture. The steps taken are to record the Padmasana in the Kahyangan Jagat Temple in Bali, followed by comparing the use of these two types of decoration on each Padmasana. The next step is to interpret the meaning by connecting the object with its past (expanding the horizon of the researcher). The results of the study show that the use of Garuda and Wilmana decoration in the Padmasana architecture is not a necessity. The use of Garuda points to the message that humans must try to free themselves from the bondage of worldly passions. While the use of Wilmana refers to the sky vehicle that carries passengers, both Giant and Dewata to the place they want. Both are symbolic decoration types, have the same position, placed on the body behind the padmasana. The position of the two becomes different if applied together, Garuda is placed in a position above Wilmana, because only a soul that has been freed from worldly slavery can ride Garuda.

Abstract

Biodiesel is considered as an important substitute for the replacement of fossil diesel due to its biodegradable, renewable and non-toxicity to environment. Biodiesel consist of mixture of mono alkyl esters of long chain fatty acids. It is produced from vegetable oils, animal fats and waste cooking oil. Solid catalysts are promising and advantageous for biodiesel production because those could be reusable, environmentally benign and are more effective than liquid catalysts. Moreover, the application of solid catalysts does not produce soaps through triglycerides saponification or free fatty acids neutralization. When triglycerides as major component of oil react with alcohol (methanol or ethanol) to form biodiesel in the presence of base catalyst, this called is transesterification. When acid catalysts are used for reducing free fatty acids to form biodiesel, this called is esterification. The application of solid catalysts in esterification and transesterification reactions for biodiesel production are discussed in this review.

Abstract

Energy conditions in Indonesia are not balanced so there is an overlap between energy demand and availability. Energy demand will continue to increase with population and industry growth, but the availability of energy will continue to decrease. Uncontrolled energy consumption will certainly increase damage to the environment which in turn worsens global warming. Energy management is a best practice so that the use of energy is well managed. Technological developments can also support energy management by utilizing IoT technology. This study conducted a systematic literature review related to the application of IoT in energy management systems. The results of the literature review conducted are that IoT which was built for energy management consists of several components, such as microcontrollers, sensors, modules, communication protocols, and cloud-based systems. Microcontrollers often used in building IoT systems are Arduino and NodeMCU. The sensor is varies depending on the measurement requirements, usually using the current sensor and voltage sensor.

Abstract

Online shop is one of the technological developments that makes it easy for sellers and buyers to make transactions. A batch of data is produced from the process at an online shop and will be wasted if not utilized properly. An example is a batch of transaction data that may store hidden information that might benefit the online shop, such as information on customer transaction patterns or information on the relationship between two or more items that are most often purchased by customers. Based on that problem, this research conducts market basket analysis using one of the data mining methods, namely Association Rule with FP-Growth Algorithm, to find hidden information in a transaction data produced by an online shop. The data used in this research is an online shop transaction data that contains more than one item from November 2019 to December 2019 owned by one of the textile industries located in Ubud, Bali. The calculation of the FP-Growth Association Rule also tested using the Weka application. The results of market basket analysis are several associative rules related to the combination of best-selling items, such as “customers who buy Tigers Base Grey will have a 100% chance of buying Tribal Green too”. The result can be utilized by the textile industry owner to manage the layout of the online shop, add item recommendation features to the online shop based on items purchased by the customer, and also keep stock of the best-selling items to prevent running out of stock.
