Abstract

Kemajuan teknologi komunikasi terutama smartphone tumbuh dengan pesatnya di seluruh penghujung dunia. Lembaga riset Emarketer bahkan memperkirakan bahwa pada 2018 akan ada 100 juta orang pengguna smartphone.  Saat ini, smartphone berbasis android menjadi solusi untuk mengakses ilmu dan informasi. Mempelajari Tenses dan Passive Voice adalah hal yang paling mendasar bagi seorang pemula yang ingin memahami Bahasa Inggris. Mempelajari Tenses dan Passive Voice dengan membuka buku-buku bahasa Inggris dirasakan kurang praktis dan kurang interaktif. Dengan menggunakan platform Android, aplikasi ini diharapkan dapat membantu masyarakat khususnya anak-anak dan remaja sebagai media alternatif dalam sistem pembelajaran tanpa batasan waktu dan tempat. Perangkat lunak yang digunakan dalam pembuatan aplikasi ini adalah Android-SDK (Software Development Kit), paket instalasi JDK (Java Development Kit), Eclipse Indigo, dan aplikasi ini diuji coba pada emulator Android.

Abstract

The problem of data security is still a matter of concern in the digital era like today. An effective security method is needed and it is difficult to break into. Encryption is an effective method of ensuring data security. The encryption algorithm is built using a chaotic cipher base so that performance in securing data and information increases. The new chaotic composition resulting from two chaotic maps will have better randomness. Logistic Map and Circle Map were chosen because they have good randomness. The new chaotic composition is called the Logistic Circle Map (LC Map). By bifurcation diagram test, Lyapunov Exponent, and NIST random test, the best density occurs at X_0=0.9 , K = 1000, r = 3.7 and Ω = 0.4. The new chaotic composition parameters have passed all 16 NIST (National Institute of Standards and Technology) tests. There are four parameters used in this study in order to obtain a sufficiently high key space, namely 1.296 ×〖 10〗^84 combinations and having a high level of lock sensitivity of 10−17. The image encryption algorithm of the LC Map function has high resistance against various attacks. This can be proven by carrying out key space tests, sensitivity tests for key spaces, histogram tests, entropy, correlation coefficients, and differential tests using the UACI NPCR. The test results on digital image decryption using the Mean Square Error (MSE) show a result of 0 and the Peak Signal to Noise Ratio (PSNR) shows a result of ∞. That is, the encrypted image is similar to the original image.

Abstract

Abstrak: Artikel ini menggambarkan bgaimana minat penggunaan dan tingkat kepercayaan terhadap aplikasi pencatatan keuangan Si Apik untuk UMKM dikeluarkan oleh Bank Indonesia. Kajian ini melihat pada beberapa fitur tersedia di dalam aplikasi Si Apik, di kaji dari fitur layanan, tingkat kegunaan, kemudahan, keamanan, kepercayaan dan minat penggunaan. Studi kasus pada UMKM binaan dibawah naungan rumah baca ABADIBA dan sebagai wujud pengabdian Masyarakat dengan jumlah responden sekitar 120 responden pelaku UMKM di wilayah Tangerang. Kajian menggunakan model SEM – structural equation modelling, Berdasarkan nilai outer loading setiap indikator memenuhi kriteria dan persyaratan validitas konverger, yaitu bernilai di atas 0,60 dan kajian ini bersifat confirmatory. Nilai contruct reliability dinyatakan bernilai di atas 0,70 dan setiap konstruk memenuhi persyaratan reliabilitas. Model struktur telah memenuhi model fit SEM-PLS dengan nilai SRMR sebesar 0,037 nilai NFI sebesar 0,855 nilai RMSTheta bernilai 0,235 maka dapat dinyatakan bahwa model diajukan memenuhi persyaratan model fit. Analisis dari studi minat penggunaan terhadap aplikasi pencatatan keuangan Si Apik memberikan gambaran bahwa tingkat kepercayaan terbentuk dari keamanan dan kegunaan, dan minat penggunaan terbentuk dari kepercayaan, kegunaan dan keamanan. Konstruk kemudahan dan layanan memberikan pengaruh tidak signifikan dengan kemudahan memiliki hubungan negatif terhadap kepercayaan dan minat penggunaan serta layanan memiliki hubungan negatif terhadap kepercayaan.

Abstract

Companies that carry out production activities necessarily want the company's goals to be achieved, one of which is optimal profit. Maximum profit in production can be realized by planning the optimal amount of production. The purpose of this study consists of four, namely making a profit formulation to maximize the amount of production, determining the optimal number of brown bread variants that will be produced at Win Bakery, determining the maximum profit in producing bread at Win Bakery, and predicting profits for return on investment. This research was conducted using a linear programming model. Decision variables determine the decisions that will make to achieve the optimal solution. The objective function is a function that describes the goals or objectives in linear programming problems. Relating to the optimal use of resources to obtain maximum profit or to use minimum costs. A constraint function is a form of formulation of the obstacles faced in achieving the goal. The results obtained from the research are the decision variables, with X1 being the number of square chocolate bread productions and X2 is the number of round chocolate bread productions. The objective function of the profit per unit is to maximize Z = 1000X1 + 800X2. The constraint function is the raw material used in making chocolate bread. Furthermore, the optimization of production with POM-QM resulted in the number of square chocolate bread production of as many as 13 pieces and round chocolate bread as many as 25 pieces so that the profit gained in one day was Rp. 32,500. The next calculation, the break-even point by entering fixed costs, variable costs, and profits obtained results in units of 55 units and the total profit earned is Rp. 1,777,00.

Abstract

The purpose of this study is to determine the effect of motivation, promotion, and destinaton image on visitor satisfaction through the decision to visit as an intervening variable at the Saung Angklung Udjo tourist attraction. The methods of analysis of this study used quantitative primary data, the test stages carried out are validity test, reliability test, and structural equation model (SEM). The data used in this study used a questionnaire instrument that was collected as many as 150 respondents. The sampling method in this study is non probability sampling with purposive ampling technique. Testing tools used SPSS and AMOS. The result of the study indicate that the motivation and destination image variables have a positive and significant effect on the decision to visit. The variables of promotion, destination image, and decision to visit have a positive and significant effect on visitor satisfaction. While the promotion variable does not have a positive and significant effect on decision to visit and the motivation variable does not have a positive and significant effect on visitor satisfaction.

Abstract

Program penelitian dan pengabdian kepada masyarakat ini memiliki beberapa tujuan utama. Pertama, program ini bertujuan untuk memberikan pengetahuan dan keterampilan kepada siswa-siswi dalam kelompok bimbingan belajar di rumah baca ABADIBA, Insan Citra Utama, Mutiara Qolbu Indonesia, dan Batin Al Birru Indonesia Jaya melalui kegiatan baca, tulis, dan berhitung. Kedua, program ini melibatkan pendampingan dalam manajemen dan administrasi perpustakaan di rumah baca yang sama. Ketiga, program ini menyediakan penyuluhan, pelatihan, dan edukasi terkait kewirausahaan, inovasi, dan pembekalan ide usaha kewirausahaan kepada kelompok masyarakat UMKM dan masyarakat umum. Program ini fokus pada kelompok bimbingan belajar tingkat SD, SMP, dan SMA dengan pendekatan pembelajaran yang disesuaikan dengan kebutuhan siswa. Selain itu, program juga mendukung komunitas UMKM dan masyarakat umum untuk memahami dan meningkatkan kemampuan berwirausaha. Tujuan akhirnya adalah meningkatkan hasil pendidikan, pelayanan perpustakaan yang lebih baik, dan ekonomi usaha yang dikelola oleh masyarakat. Namun, program ini menghadapi tantangan, terutama akibat pandemi COVID-19 dan penerapan PSBB. Beberapa kegiatan harus diubah dan disesuaikan dengan protokol COVID-19, seperti mengalihkan pelatihan masyarakat ke pendekatan virtual dan kelompok kecil.
