Abstract

Kota batu merupakan salah satu kota di Indonesia yang menyandang predikat sebagai kota wisata. Kota di Provinsi Jawa Timur, Indonesia. Kota ini terletak 90 km sebelah barat daya Surabaya atau 15 km sebelah barat laut Malang. Desa wisata dan beragam potensi daerah nya merupakan aset yang sangat penting bagi Kota Batu. Ada 24 desa wisata yang telah terkelola oleh masyarakat dan perangat desa. Namun 5 tahun terakhir pembangunan objek wisata di Kota Batu hanya terfokus pada objek yang dikelola oleh swasta. Sehingga membuat potensi daerah Kota Batu tidak begitu banyak dikelola dan dimanfaatkan oleh masyarakat dan pemerintah Kota Batu. SIG yang informatif merupakan upaya untuk membantu berjalan nya konsep Smart City di Kota Batu. Di dalam SIG ini bertujuan untuk memberi informasi kepada wisatawan sehingga dapat membuat potensi asli daerah di kota batu bisa terlihat dan dimanfaatkan dengan maksimal oleh masyarakat dan pemerintah Kota Batu. Di dalam SIG ini penulis menggunakan metode Greedy untuk pencarian jalur terdekat. Algoritma greedy merupakan jenis algoritma yang menggunakan pendekatan penyelesaian masalah dengan mencari nilai maksimum sementara pada setiap langkahnya. Nilai maksimum sementara ini dikenal dengan istilah local maximum. Pada kebanyakan kasus, algoritma greedy memberikan solusi yang mendekati nilai optimum dalam waktu yang cukup cepat.

Abstract

Hidroponik merupakan budidaya menanam dengan memanfaatkan air tanpa menggunakan tanah dengan menekankan pada pemenuhan kebutuhan nutrisi bagi tanaman. Penerapan hidroponik lebih efisien di daerah yang memiliki ruang hijau terbatas. Salah satu jenis hidroponik adalah Deep Flow Technic (DFT) merupakan jenis hidroponik yang menerapkan aliran nutrisi secara kontinyu dan terdapat genangan setangah dari diameter pipa yang menggenangi akar tanaman. Namun, seringkali para penggiat hidroponik sistem DFT ini mengalami kegagalan selama proses pertumbuhan tanaman, dikarenakan kurangnya penjagaan terhadap unsur tumbuh tanaman seperti sirkulasi air, intensitas cahaya, suhu, kelembaban dan pH air yang menyebabkan tanaman tersebut tidak tumbuh optimal. Maka diperlukan sistem monitoring dan pengendali sirkulasi air pada hidroponik DFT berbasis IoT untuk mengantisipasi terjadinya perubahan pada unsur tumbuh tanaman. Tanaman yang digunakan adalah sawi daging (pakchoy). Data unsur tumbuh tanaman diakusisi oleh sensor yang terintegrasi dengan Raspberry Pi. Pada proses monitoring menggunakan website akan menampikan data unsur tumbuh tanaman berupa pH, suhu, kelembaban dan ketinggian air pada tandon hidroponik. Suhu dan kelembaban digunakan sebagai parameter pengendali sirkulasi air yang diproses menggunakan Metode Fuzzy Sugeno untuk menyalakan atau mematikan pompa pada hidroponik DFT. Dari hasil pengujian yang telah dilakukan, sistem dapat melakukan monitoring unsur tumbuh tanaman yang ditampilkan pada website secara realtime serta pengendalian sirkulasi air secara otomatis. Sistem yang diterapkan dalam hidroponik tanaman sawi daging ini pun menghasilkan pertumbuhan jumlah daun dan tinggi tanaman yang signifikan.

Abstract

Meeting minutes can also be used as a benchmark for whether the meeting objectives have been achieved or not. Minutes are taken during the meeting until the end of the meeting, which contain essential points from the meeting. Minutes in online meetings are currently still done manually, and generally, every meeting is recorded as documentation that requires more human resources to change the recording of the meeting file. Based on the problems above, a solution to this problem is needed by creating an automatic note-taking system that can assist the note-takers in concluding the meeting, especially in the Information Technology Department. This study uses the latent Dirichlet allocation (LDA) method to determine text summarization and topic modeling. Based on this research, the system calculation using the LDA method produces a pretty good accuracy value for text summarization of 57.91% and topic modeling with a coherence score of 64.56%. Based on this research, the implementation of the latent Dirichlet allocation method for text summarization and topic modeling provides a fairly good level of similarity accuracy when compared to the minutes that are written manually and can be implemented in the Information Technology Department.

Abstract

Most game s are used as a means of entertainment, but can also function as a means of training, education and simulation. In the field of education, educational game s can be applied by adopting educational materials to be informed in an interesting way to users. To provide a challenge to the user, the concept of level and scoring is applied in the game . The type of game made is a quiz-based educational game . Elements of educational game s made in the form of text, images, sounds and videos regarding knowledge about the classification of vertebrate and invertebrate animals. The data and answers used in the quiz are also displayed in a random way. The randomization process uses a random generator that applies the concept of Multiplicative Congruential Random Number Generator (CRNG). The use of this generator is intended so that users get different questions and answer compositions at each level. This is so that the user does not get bored quickly and the game becomes more interesting to play. So that the user indirectly conducts learning activities because the information conveyed is in the form of knowledge that is packaged in the form of a game.

Abstract

EFL learners at the tertiary level continue to struggle to understand English, especially when speaking. Certain elements become hurdles when students talk. The variables are referred to as foreign language anxiety. This phenomenon was produced by worry that interfered with students' performance: communication apprehension, fear of poor evaluation, and low self-esteem. This study employed a qualitative method with a case study methodology. The data was gathered via a questionnaire and a semi-structured interview with a non-English department student at the State Polytechnic of Malang. The questionnaire was based on Horwitz's foreign-language classroom anxiety scale. The findings of this study revealed that the most important aspects influencing student performance are avoiding mistakes that lead to poor evaluation. Suggestions for learners, that they would be more readily to speak when they get support by the new technology
