Authors: Ariska Fera , Marlin Marlin , Widodo Widodo 
Published: July 2020

Bawang dayak is the important medicinal plant that need to be developed in cultivation techniques and production. The use of Plant Growth Promoting Rhizobacteria (PGPR) recently known to be effective to increase plant growth and yield. The research aimed to determine the optimal concentration and immersion time of PGPR on the growth and yield of bawang dayak. The experiment was arrange in complete randomized block design (RCBD) consisting of two factors. The first factor is the concentration of PGPR with 4 levels namely K0 = 0 g L-1, K1 = 5 g L-1, K2 = 10 g L-1 and K3 = 15 g L-1. The second factor is immersion time of seed, namely P1 = 10 minutes, P2 = 20 minutes, P3 = 30 minutes and P4 = 40 minutes. The results showed that there was an interaction between concentration and immersion time of PGPR giving effect to the number of leaves and the number of tillers. The immersion time of PGPR for 10 minutes with a concentration of 15 g L-1produced the highest number of leaves (58 leaves) and produced the highest number of tillers (27.67 tillers). The treatment of PGPR concentration or immersion time of PGPR singly did not affect all observed variables of growth and yield of bawang dayak.

Grey Double Exponential Smoothing Dengan Optimasi Levenberg-Marquardt Untuk Peramalan Volume Penumpang Di Bandara Soekarno-Hatta
Authors: Primandari Arum Handini 
Published: July 2020

Aircraft has became the best choice for long distance traveling because it has shortest travel time than any other transportations. Moreover, in recent years, aviation industries have competed for providing low cost flight so that it can also be enjoyed by middle class society. Thus escalate the popularity of aircraft as economical carrier. Knowing the volume of passengers in advance will help government and related institutions to effectively providing facilities. The volume of passengers can be predicted using classic model such as double exponential smoothing model which is simpler and has high accuracy. However, the randomness of Indonesian passenger volume data cause double exponential smoothing (DES) cannot follow both data pattern and data trend. Moreover, classic model often encounters overfitting where the prediction is bigger than the actual data. Therefore, we employed Grey Method applied on DES (GDES) to overcome this problem. GDES enabled the researcher to perform better data fitting because it would generate smoothing curve which showed clearer trend. As the result, although GDES fitting curve had higher error measurement (MSE) than DES, the forecasting result of GDES was more precise than DES.

This research develops the theory of NN (neural network) by using CG (conjugate gradient) to speed up the process of convergence on a network of NN. CG algorithm is an iterative algorithm to solve simultaneous linear equations on a large scale and it is used to optimize the process of the network on backpropagation. In the process, a Neural netwok doing random weighting on the weight of v and w and this weight will have an effect on the speed of convergence of an algorithm for NN by the method of CG. Furthermore, generating the random numbers to take a sample as a generator in this research of neural network by using uniform distribution (0,1) methods. Therefore, the aims of this research are to improve the convergence on NN weighting using numbers which are generated randomly by the generator and the will be corrected with the CG method.Keywords: neural network, backpropagation, weighting, conjugate gradient

MENAFSIR LGBT DENGAN ALKITAB
Authors: Prior John Mansford 
Published: July 2020

<p>In his latest book the biblical theologian Gerrit Singgih looks in detail at verses in the Bible about same sex relationships that ring negative and also the few more positive examples of same sex relations. This article contrasts Singgih’s exegesis with that of Rome, both in documents from the Congregation for the Doctrine of the Faith and in the Catechism of the Catholic Church, and also in the Catechism of the Indonesian bishops. Rome states that finding oneself with “homosexual tendencies” is morally neutral while also declaring it “objectively bad.” According to Rome every sexual act has to be open to life and so homosexual relations are sinful. However, this is demonstrably wrong, as for instance, for infertile or elderly married couples. The writer concludes that he is in full agreement with Gerrit Singgih who interprets the negative verses in the Bible within the context of biblical times.</p><p> <br /> <strong>Keywords:</strong> LBGTQ+, Hermenutic Pattern, Creative Interpretation,<br /> Neutral Status, Natural Law.</p><p> </p>
