Nowadays most of the india market is moving towards an online world with an adroit to have an maximum market scope .So we are connecting the business of gift article to online world with the evolved versions of current algorithm of recommendation systems.Ecommerce is an online site where the sale or purchase of goods are ordered electronically.The available ecommerce system have some issues with the recommendation so we are collaborating the multiple algorithm to increase the product sale and convinient in user interaction

Development of Optimization Methodology for Short Range Air-to-Air Missile Romie Oktovianus Bura; Yudki Utama; Muhammad Farraz
INSIST Vol 3, No 1 (2018)
Publisher : Universitas Lampung

This paper illustrates the development and the use of conceptual sizing tools integrated with optimization tools. The conceptual sizing tool is based on empirical and simple analytical calculation that simple and robust enough for wide range of inputs. The genetic algorithm optimization method then used to explore the global optimum for given variables. System response analysis is conducted to gain insight about the sensitivity of objective function because of design variables.

Voltage Profile Improvement through Load Shedding Action Using Linear Programming-based Optimal Power Flow Lukmanul Hakim; Annisa Zauhar Nafisah; Heri Gusmedi; Khairudin Khairudin

Publisher : Universitas Lampung

This paper proposes a load shedding scheme to improve voltage profile of a power system. A linear programming approach to optimal power flow is utilized to obtain optimum amount of load to shed in order to bring power system to an acceptable operating region. In this work, ±5% voltage variation is considered to be acceptable and hence, an immediate control action should be taken if power system is operated beyond this limit. The proposed method was tested on the IEEE 57-bus test system. Results showed that the proposed approach was able to provide a minimum amount of load shedding action to improve voltage profile of the studied power system.

Synthesis and Characterizations of Hydroxyapatite from Bovine Bone Using Alkaline Hydrolysis Method Nuning Aisah; Muslim Efendi Harahap; Dwi Budianto; Mirza Wibowo; Mohammad Dachyar Effendi; Jan Setiawan; Seto Roseno; Dwi Gustiono

In this research, the synthesis of hydroxyapatite compound (HAp) has been done by extracting technique from cow cortex thigh bones to eliminate organic compounds contained in bone so that it can be used as raw material of bone graft. The method used is alkaline hydrolysis method of soaking bone in NaOH solution with variation of concentration (1M, 2M, 3M) and immersion time (30 minutes, 60 minutes, 90 minutes). The extracted HAp powder was then analyzed using FTIR, XRD and SEM. The results showed that a hydroxyapatite powder with a soaking time of 30 minutes and a 2M and 3M NaOH concentration did not contain organic elements. The XRD peak pattern shows the phase formed is a hydroxyapatite with a hexagonal structure having an average crystal size of 10-12 nm.

Implementation of Augmented Reality as Information and Promotion Media on Dieng Tourism Area Banu Nur Affan; Agus Suryanto; Arief Arfriandi
INSIST Vol 3, No 1 (2018)
Publisher : Universitas Lampung

Information becomes necessary for tourists to get and improve the knowledge of tourism and their experiences about tourist destination. In Dieng tourism area, tourist information and promotional media has not been structured, as well as the need of media. The purpose of this research is produce Augmented Reality application that can visualize information of Dieng tourism, as interactive and interesting information, promotion tourism media. This research produces an android application which is used as information and promotion media of tourism in Dieng. Testing according to ISO 25010 with functional suitability got 100% suitability with Blackbox test, on portability aspect application successfully installed, update and uninstall on various smartphone environment, on performance efficiency aspect show average launch time is 1817 ms and also 0,22% CPU and 177,8 MB Memory usage. Results usability obtained SUS score 79.6 indicates the application get acceptable category to be used as information and tourism promotion media in Dieng.

Anaerobic Wastewater Treatments: Prediction of Retention Time on RT/RW Plant Dessy Agustina Sari; Sukanta Sukanta; Azafilmi Hakiim

Publisher : Universitas Lampung

Wastewater treatment gave major problem in higher of chemical oxygen demand that backgrounded by amount and type of PT RT/RW products. The waste was polymer, mixture of nitrogen, mixture of phosphate, and oil. This factory used active sludge and microorganism (anaerobic condition). Research result showed that pH ranged 4,94 until 8,02. This data gave a decreasing sharply in acidic condition. The thing could be caused acetogenic phase in area pond anaerobic. The phenomenon might be recited because possibility of biologist living this waste did not take place as well and or could give deathly affect to the anaerobic bacteria. Customary pH for the bacteria was 6,8 – 7,4. Temperature data reached 28-33oC so their activities were good. Then, efficiency of anaerobic wastewater treatment was 62,95 to 66,06%. The data indicated that the research was not accordance with SOP companies. Inlet concentration of chemical oxygen demand had variation and gave unbalancing affect to digestive bacteria load. Estimation to get valid COD was 11-14 days. The duration was required by the microorganism to digest the matter organic perfectly to be methane and carbon dioxide gas.
