Published: March 2021

Abstract
The population of cattle in Indonesia reaches 17 million in 2018, but until now Indonesia does not yet have an integrated identification and recording system for cattle between farmers and / or farmer groups and the government, in this case the Livestock Service Office. The objective of this research is to build a prototype of national cattle identification and database system based on information technology. The prototype development system uses a prototyping method, preceded by surveys and interviews with farmers in several locations, namely Kupang Regency, Kupang Municipality, Tuban, Bogor and Bojonegoro. The result of this research is a prototype of a national cattle identification and database system that can be accessed using computers and smartphones by actors in the livestock industry. Cattle will obtain an identity in the form of a code written into the RFID tag issued by the district or municipal Animal Husbandry Service and recorded in a database. The identity is unique, that no cattle will have the same identity and it is valid for life. Farmers, farmer groups and companies engaged in livestock farming will also be recorded in the database so that it will facilitate national cattle management. The resulting prototype will be a model of a livestock database system in Indonesia.

Abstract
University of Darussalam Gontor (UNIDA Gontor) is one of the universities that has been developing quite significantly in Ponorogo area since 2014, especially in terms of facilities and infrastructure. Until now, UNIDA Gontor has a development master plan in physical form in the form of paper. However, there are several drawbacks to the physical prototype. First, physical documents are vulnerable to damage and loss. Second, with the condition of the campus that continues to develop, it is difficult to update the prototype in physical form. Third, physical documents cannot provide a visual representation of the buildings that have been and will be built. To overcome some of these weaknesses, it is necessary to have a solution with technology that is adaptive to needs. The purpose of this research is the design of 3-dimensional modeling of buildings in UNIDA Gontor area that can be accessed easily and dynamically. The project design is based on the steps of the waterfall model with the following stages: (1) Requirements, (2) Design (3) Implementation, (4) Verification, and (5) Maintenance. Testing is done by testing a 3-dimensional display with a 3D image viewer which shows a success rate of 90% working as expected. The test is also carried out by measuring the level of color suitability, layout and comparison of the size of the 3D media with the actual building size, implemented through distributing questionnaires to relevant parties at the university and the public gets 88% according to their wishes. The resulting media is a adaptive building asset based on 3D modeling that can be accessed easily anytime and anywhere. With various existing features, it is hoped that the resulting media can facilitate access for the community and the development activities carried out at UNIDA Gontor. The long-term benefits of this research are taken into account in the framework of the university’s development plan and its infrastructure.

The Effects of the Concentration of Red and Yellow Gambier Fruit Dyes on the Short-Circuit Photocurrent in Dye-Sensitised Solar Cells
Authors: Nasyori A , Noor F A 
Published: March 2021

Abstract
Natural dyes still have low efficiency, although there are good opportunities to apply them in dye-sensitised solar cells (DSSCs). In this research, the working-electrode was prepared from indium tin oxide (ITO) and titanium oxide (TiO2), using the doctor blade method for doping TiO2 on ITO glass. Then, the working-electrode was soaked in gambier extract for 24 hours. The counter-electrode and electrolyte were made from burning a candle and mixing KI + I2, respectively. UV-vis and FTIR spectra have been made to investigate the effect of the concentration of red and yellow gambier prepared by maceration and evaporation from methanol. They were used to analyse absorbances and compounds in gambier, respectively. From UV-vis and FTIR spectra results, we obtained that the organic dyes from the red and yellow gambier fruits could have a high potential to be used as a sensitiser to absorb photons in DSSCs. From the I–V measurement, we found that the efficiency tends to increase as the concentration increases. It indicates that the concentration of natural dyes could increase the performance of DSSC. Furthermore, an efficiency of 3.248% was found to be achievable for DSSCs from a 70% concentration of yellow gambier fruit dye.

Published: March 2021

Abstract
Until 2020, one province and two cities in Indonesia have local regulations governing green buildings’ implementation. Besides, there is also a ministerial regulation governing green building implementation, which serves as the primary reference for various cities or provinces that do not have local green buildings regulations. Three of the four laws are more than four years old. The implementation of these regulations has resulted in various achievements and findings and multiple obstacles. It is time to review these criteria so that the green building concept’s performance is broader and more weighty. This study aims to review these regulations’ requirements, particularly the requirements related to passive strategies, and propose further development directions. We were researching by dissecting the criteria contained in the rules, analyzing the potential impacts generated, and then comparing them with the opinions of building stakeholders. In the future, the green building regulation criteria need to prioritize measures that can significantly impact the environment and energy, and people as the three essential factors of the green building concept.

Published: March 2021

Abstract
Artemisinin is a compound extracted from Artemisia Annua. Artemisinin is used globally as the first-line antimalarial drug. Despite its high efficacy against the malaria parasite, artemisinin has low bioavailability because it has low solubility in water. This present study was conducted to prepare and characterize the self-emulsifying drug delivery system of artemisinin to increase the dissolution profile of artemisinin. The stability of the resulting emulsion was observed visually for 6 hours. Droplet size, polydispersity index, and zeta potential of the emulsion were measured using Nano Particle Analyzer. The optimum formulation was evaluated with the dissolution test and compared with the artemisinin crystal. Several formulations have good stability of the resulting emulsions where no creaming or flocculation was formed during the observation. Droplet sizes of the resulting emulsions ranged from 114.17-247.93 nm and the polydispersity index of the emulsions ranged from 0.35- 0.56. Zeta potential values of the selected formulations were found in the range of -23.23 - -2.33 mV. Fourier Transform Infrared Spectroscopy spectra of self-emulsifying drug delivery system showed the presence of artemisinin in the formulation with lactone and peroxide peaks. The dissolution of artemisinin in the self-emulsifying drug delivery system was significantly increased compared to artemisinin crystal. Artemisinin was released up to 98,6 %in 150 minutes in self-emulsifying drug delivery system formulation.

Published: March 2021

Abstract
Let G be an arbitrary non-trivial connected graph. For every two vertices u and v in G, a (u,v)-path in G is called a rainbow (u,v)-path if all edges are colored differently. Next, a rainbow (u, v)-geodesic in G is a rainbow (u,v)-path of length d(u,v). Graph G is rainbow connected if for every two vertices u,v ∈ V(G), there exists a rainbow (u,v)-path. If there exists a rainbow (u, v)-geodesic in G for every two vertices u, v ∈ V(G) then G is strongly rainbow connected. The rainbow connection number rc(G) is the minimum number of colors needed to make G rainbow connected, while the strong rainbow connection number src(G) is the minimum number of colors needed to make G strongly rainbow connected. Let Trn be the generalized triangle-ladder graph for n ≥ 2. The triangle-net graph, denoted by H = (Trn)m, is constructed by taking m homogeneous generalized triangle-ladder graphs and identifying their terminal vertices, for m ≥ 2. This paper determined the rainbow connection number of the triangle-net graph and the upper bound of the strong rainbow connection number of the graph.
Robustness Test of SIMON-32, SPECK-32, and SIMECK-32 Algorithms Using Fixed-Point Attacks
Authors: Susanti B H , Permana O J , Amiruddin  
Published: March 2021

Abstract
SIMON-32 and SPECK-32 are a family of lightweight block ciphers publicly released by the National Security Agency (NSA) in June 2013. Meanwhile, SIMECK-32 is a lightweight block cipher based on the combination of good design components from SIMON- 32 and SPECK-32 block ciphers. In this paper, we tested the robustness of the SIMON-32, SPECK-32, and SIMECK-32 algorithms against fixed-point attacks. Block cipher fixed-points may facilitate fixed-point attacks if an adversary can control the block cipher key input. The results of fixed-point attacks on the SIMON-32, SPECK-32, and SIMECK-32 algorithms show that all three variants of the algorithm have fixed-points.
