It is also mandatory to recalculate the values to ensure the correct result is obtained. In this research, a website-based assessment system called “Website-Based Prisoner Risk Assessment Information System at Class IIB Selong Correctional Institution” is designed and built to help classify prisoners based on risk levels (low, medium, and high) which yields calculations results corresponding to the assessment guidelines. To support the website development, the object-oriented Rational Unified Process (RUP) software development method is deployed. Rational Unified Process (RUP) is chosen because it allows real-time explanation of the development process, has a clear system documentation, and flexible development process. The developed system is then tested using black-box testing and questionnaires. The black-box testing result is 1, which shows that all features in the system run correctly. Usability testing shows results at 89,7% which can be interpreted as “Very Good”, which infers that RUP is the right method for the system development.</p> anggin risna Nadiyasari Agitha Royana Afwani ##submission.copyrightStatement## 2021-10-25 2021-10-25 3 2 155 166 10.29303/jtika.v3i2.120 Implementasi Internet of Things (IoT) untuk Pengawasan dan Penyiraman Otomatis pada Budidaya Cacing Tanah dengan Protokol MQTT http://jtika.if.unram.ac.id/index.php/JTIKA/article/view/126 <p><em>The earthworm (Lumrbricus rubellus) has a special value that made it the material for cosmetics and medicine, the special value of the earth worm made it a cultivable animal.

Setiap hari manusia menghasilkan sampah, baik sampah organik maupun anorganik yang memiliki berbagai bentuk dan jenis. Tidak heran permasalahan tersebut juga banyak ditemukan di lingkungan Perumahan. Salah satu perumahan yang ada di Kota Mataram adalah perumahan Babakan Permai yang terletak di kelurahan Babakan, kecamatan Sandubaya, Kota Mataram. Penanganan masalah sampah di Perumahan Babakan Permai ditangani dengan cara penjadwalan untuk pengambilan sampah pada masing-masing rumah. Sampah di ambil setiap 2 kali seminggu oleh petugas sampah perumahan. Hal ini memiliki kekurangan yaitu potensi penumpukan sampah pada tiap rumah meningkat. Penumpukan sampah sangat mengganggu warga di lingkungan sekitar baik dari segi kebersihan maupun kesehatan Dengan demikian, permasalahan tersebut dapat di atasi dengan membuat alat <em>Smart Trash Can</em> yang dapat mempermudah petugas sampah di perumahan. Tugas akhir ini berupa <em>prototype </em>tempat sampah pintar yang dapat memonitoring tempat sampah. Hal tersebut dapat dilakukan dengan menerapkan konsep IoT (<em>Internet of Things</em>) yang memanfaatkan internet. Protokol yang digunakan dalam IoT adalah MQTT (<em>Message Queuing Telemetry Transport</em>) yang bersifat<em> lightweight message </em>dan didesain untuk perangkat-perangkat dengan sumber daya terbatas. Dengan konsep IoT, monitoring tempat sampah dilakukan dengan menggunakan beberapa sensor seperti penggunaan sensor berat (<em>load cell</em>) sebagai deteksi berat sampah, modul HX711 sebagai konversi nilai berat <em>load cell</em> dan sensor<em> magnetic switch </em>untuk mengetahui bukaan/tutupan tempah sampah yang di rangkai dengan mikrokontroler.</p> MUH.

The development of network security system demands a better security, especially in servers. However, there are still weaknesses in the server that controls incoming packet which results in more vulnerable it is to be stormed by Denial of Service and Brute Force attacks on the system. This study aims to improve network security performance using the Port Knocking and Honeypot methods which will be combined with the Iptables method. From the tests carried out with the addition of the IPTables method, an increase in performance of CPU usage (38.4%) and memory (44.2%) on servers and network security were obtained compared to those that only use the Port Knocking and Honeypot methods.</em></p> Yayank Muhammad Abdussyakur Ahmad Zafrullah Mardiansyah Andy Hidayat Jatmika ##submission.copyrightStatement## 2021-10-25 2021-10-25 3 2 35 45 10.29303/jtika.v3i2.144 Deteksi SMS Spam Berbahasa Indonesia menggunakan TF-IDF dan Stochastic Gradient Descent Classifier http://jtika.if.unram.ac.id/index.php/JTIKA/article/view/145 <p><span lang="IN">Short Message Service (SMS) has evolved in the last few decades. The simplicity of SMS makes this short message service attractive to use as a direct communication service on mobile devices. As the popularity of this service increases, it also harms attacks on mobile devices such as SMS spam. Spam SMS are short messages that the recipient doesn't want, such as advertisements and scams. Spam SMS can overwhelm your inbox and make your mobile device experience less good. One way to overcome this problem is to implement a machine learning model to automatically recognize and filter Spam SMS. This research aims to build a machine learning model that provides higher accuracy for detecting SMS spam in Indonesian using the TF-IDF method and the Stochastic Gradient Descent Classifier. Based on the test results, the model built can detect SMS spam and not spam with an accuracy of 97%.</span></p> Ramaditia Dwiyansaputra Gibran Satya Nugraha Fitri Bimantoro Arik Aranta ##submission.copyrightStatement## 2021-10-25 2021-10-25 3 2 200 207 10.29303/jtika.v3i2.145 Rancang Bangun Sistem Pendukung Keputusan Inventory Pakaian Adat berbasis Web menggunakan Fuzzy Inference Tsukamoto (Studi Kasus : Toko Bali Antic) http://jtika.if.unram.ac.id/index.php/JTIKA/article/view/150 <p>Traditional clothing is a symbol of clothing in an area that has an identity and is characterized as a relevant cultural symbol. Inventory control is very important to take into account because shortage or excess inventory is a factor that triggers an increase in costs. In daily operations, the data collection process that is still done manually is mostly done in clothing sales stores, so there are many mistakes from the responsible departments such as sales, the absence of forecasting the need for goods is also a problem for the efficiency of store operational costs. This research was developed in line with the problems that are often faced at the Bali Antic Shop. Seeing this, a website-based custom clothing inventory decision support system was developed using the Tsukamoto fuzzy method. This system is applied in determining the percentage of sales with input variables of price margin, demand and existing inventory. In this research, it is proven by comparison between manual calculation and system calculation, and the result is the percentage of sales.</p> I Made Subiantara Putra I Gde Putu Wirarama Wedaswhara W.

The traditional method that is often used to distinguish the freshness of squid by local people is from the body color and smell of the squid. This method is very simple but has many shortcomings <br>in distinguishing freshness from squid. The drawback of this method lies in the understanding and level of accuracy of each person who is different. So it is necessary to create a system that can distinguish the freshness level of squid <br>automatically only from the image of the squid. In this study, a system model was developed that can classify the freshness level of squid using the Support Vector Mahine (SVM) method. The GLCM and histogram methods as well as <br>the HSI color space are used for texture and color feature extraction. This study uses three types of classification. The total data used in this study are 360 body images of squid that have been cropped and resized by 128 x 128 pixels for <br>the treatment type class. The total data for the freshness class with three types of classes is 495 and the total data for the freshness class with two types of classes is 330. In this study, the process of cropping, augmentation, resizing and <br>conversion of color space in the dataset was carried out. The distribution of training data and test data is 70:30. The highest accuracy obtained is 67.75%.</p> fathin zulian tsany Fitri Bimantoro Gibran Satya Nugraha ##submission.copyrightStatement## 2021-10-25 2021-10-25 3 2 220 231 10.29303/jtika.v3i2.156 Rancang Bangun Aplikasi Transliterasi Aksara Latin menjadi Aksara Sasak Menggunakan Algoritma Rule Based Berbasis Android http://jtika.if.unram.ac.id/index.php/JTIKA/article/view/157 <p><em>The Sasak script is one of the cultural heritage of the Sasak people on the island of Lombok. But lately, the Sasak script has begun to be rarely used among the Sasak people, especially among the younger generation. If this continues, the existence of the Sasak script is threatened with extinction. One of the efforts in preserving the Sasak script is digitizing the Sasak script to digital technology devices by utilizing Unicode. In this research, the author will make an android-based transliteration application and develop a rule-based algorithm that refers to the rules of the Sasak script. The string replacement method with hexadecimal addressing derived from the UTF-16 Unicode is used to adjust the Latin characters with the writing rules of the Sasak script. Digital writing of the Sasak script using 47 symbols from Unicode Balinese block on “1B00-1B7F”. To transliterate Latin script into the Sasak script, the author has developed 1704 rule-based rules to apply all the rules of writing the Sasak script. The accuracy test towards on 3 data sources, namely testing of street signage in Mataram City obtained an accuracy value of 97.20% from 250 data test, testing of "Bali-Indonesian Latin and Balinese script" dictionary obtained an accuracy value of 96,375 from 800 data test, and testing of Lontar Doyan Neda (Dewi Anjani) obtained an accuracy value of 65.33% from 600 data test.

It is not efficient because it time consuming or other activities just for waiting. Thus, we need a system that can be used by patients to see the queue wherever it is. In this final project, a hospital pharmacy queue information system is designed. This information system is designed on a web basis so that patients can access through all platforms which will be used by patients to make it easier to see the queue. In making the system, the prototype method is used so that it can be evaluated periodically when finding problems in the system. The advantage is the system can be fixed immediately if a bug is found. In this system, there are two users, consist of patients and pharmacy staff, this system also makes it easier for patients to predict queues because patients can see the queue status and drug status (concocted or non-concocted) at the pharmacy. So the patients can leave the waiting room when the queues are congested and return to the waiting room when they are about to have their turn. The results of this system enable RSUD Praya to saw the average length of queues for concoctions and non-concoctions at the Praya Hospital pharmacy per month. So that it can measure the service level whether it meets the SOP that has been determined or not.</p> Lalu Novalino Roasta Ramadhan Moh.
