The ordinary information systems had low interoperability, therefore they can only be operated through uniplatform, local access, single database, and single user. The invention of Internet and HTML hadlead some information system changes to be based on the web. Information system based on web have ahigher interoperability level, meaning that they can be operated through multiplatforms, remote access,multidatabases, and multiusers. The purpose of this research is to evolve some strategies and investigatesome components which are needed to conduct the migration of information system, from the ordinaryinformation systems to information systems based on the web. As a case study, migration strategies on anoperational ordinary information system with rigorous complexity are implemented. The migration of information system can be done through two strategies, with the same operatingsystem or different one. The only component that has to be migrated in the same operating system platformis the DBMS programs. On the other hand, the components that have to be migrated in the differentoperating system platform are the components of database and the DBMS programs. The database migrationcan be done by converting the database tables and move the data to the new database tables, whereas theDBMS migration can be done by rearranging the DBMS programs into the web aplication form by using CGIand HTML. In order to interact with the database, the suitable database drivers or ODBC have to be used. The conclusion of this research are : (1) web needs CGI and database drivers to interact with thedatabase, (2) the migration of the database from xBase to mSQL database tables can be done by usingdbf2msql, (3) the suitable information to be accessed through the web are those that are always available tobe accessed through remote multiusers, (4) the most important web aplication contains passwords, and (5)the information systems based on the web support the client/server system.

Hajj guidance is a simulation activity carried out by pilgrims so that pilgrims can better prepare themselves. Even though they have carried out the guidance for Hajj, sometimes the congregation still feels that they do not understand the material they are learning and feel that they have not learned enough about the object of Hajj by using guide books, especially the practice of the Hajj. But pilgrims have not taken the guidance of other Hajj because of the cost, time and place they need. By using virtual reality based on 360-degree videos, pilgrims can understand the material better and can perform the pilgrimage independently without being hindered by time, place and cost. The research was conducted using Research and Development (R&D) research methods and then using a quantitative approach to approach the application. The instruments used in this research include material expert test sheets, media test sheets, and user usability test sheets. The results show that virtual reality (VR) based on 360-degree video is a media that is feasible to use and has very good benefits for prospective pilgrims.

Image segmentation is one of the most critical steps in computer-aided diagnosis that potentially accelerate leukemia diagnosis. Leukemia is categorized as blood cancer known as a deadly disease. Generally, acute lymphoblastic leukemia (ALL) detection can be done manually by counting the leukocytes contained in the stained peripheral blood smear image using the immunohistochemical (IHC) method. Unfortunately, the manual diagnosis process takes 3−24 hours to complete and is most likely inaccurate due to operator fatigue. An image segmentation method proposed by Vogado can achieve an accuracy of 98.5%. However, this method uses a K-means clustering algorithm that is not optimal for input images containing mostly noise. In this research, fuzzy c-means were applied to solve this problem. The dataset used in this study was ALL-IDB2, which consisted of 260 images, with each image having the size of 257×257 pixels in tagged image file (TIF) format. The initial stage of this method was to divide the ALL-IDB 2 acute leukemia dataset image into cyan, magenta, yellow, key (CMYK) and L*a*b color schemes which then subtract the M component subtracted by component *b. The subtraction results were then splits using the FCM algorithm, resulting in the nucleus and background sections. The output of this method was then evaluated and measured using the metrics accuracy, specificity, sensitivity, kappa index, dice coefficient, and time complexity. The results showed that changing the clustering algorithm in the image segmentation method did not provide a significant change in results; an increase occurred in the specificity and precision metrics with an average of 0.1−0.4%, the execution time also increased by an average of 23.10%. The decrease in the accuracy metric was down to 95.4238%, and the dice coefficient value was 79.3682%. From the explanation above, it can be concluded that the application of the FCM algorithm to the segmentation method does not provide optimal results.

Abstrak: Desa Wisata Melung memiliki beberapa UMKM lokal yang menciptakan produk pangan khas seperti kopi melung dan keripik nangka. Walaupun demikian, pertumbuhan jumlah UMKM pangan belum diimbangi dengan peningkatan daya saing produk. Salah satu langkah untuk meningkatkan daya saing adalah melalui sertifikasi halal dari Badan Penyelenggara Jaminan Produk Halal (BPJPH). Namun, hasil observasi mengungkapkan bahwa pengetahuan pelaku UMKM di Desa Wisata Melung tentang pentingnya sertifikasi halal masih kurang. Oleh karena itu, dibutuhkan pendampingan untuk memberikan pemahaman tentang pentingnya sertifikasi halal dan proses pengajuannya. Pendekatan ini melibatkan survei, observasi lapangan, pendampingan, dan evaluasi. Mitra pendampingan adalah 15 pelaku UMKM di bawah naungan Badan Usaha Milik Desa (BUMDES) Melung. Pre-test dan post-test digunakan untuk mengukur pencapaian tujuan kegiatan pendampingan. Pada pre-test dan post-test, jumlah soal yang digunakan ada 18 butir soal. Indikator keberhasilan kegiatan ini adalah sebanyak >80% peserta memahami pentingnya sertifikasi halal dan >80% peserta memahami dokumen yang diperlukan dalam proses pengajuan sertifikasi halal. Hasil post-test menunjukkan bahwa 100% peserta memahami pentingnya sertifikasi halal dan 87% memahami dokumen yang diperlukan dalam proses pengajuannya. Dengan adanya kegiatan ini, diharapkan 100% produk pangan UMKM Desa Wisata Melung mendapatkan sertifikasi halal agar dapat meningkatkan daya saing produk mereka.Abstract: The Melung Tourism Village has several local Micro, Small, and Medium Enterprises (UMKM) that produce typical food products such as Melung coffee and jackfruit chips. However, the growth in the number of UMKM food businesses has not been accompanied by an increase in the competitiveness of their products. One step to enhance their competitiveness is through halal certification from the Halal Product Assurance Agency (BPJPH). Nevertheless, observations have revealed that the knowledge of UMKM practitioners in Melung Tourism Village regarding the importance of halal certification is still lacking. Therefore, it is necessary to aid impart an understanding of the importance of halal certification and the application process. This approach involves surveys, field observations, assistance, and evaluation. The assistance partners consist of 15 UMKM practitioners under the auspices of the Melung Village-Owned Enterprises (BUMDES). Pre-tests and post-tests are used to measure the achievement of the assistance objectives. In both the pre-test and post-test, there are 18 items of questions. The success indicators of this activity are that >80% of the participants understand the importance of halal certification and >80% of the participants comprehend the required documents in the halal certification application process. The post-test results show that 100% of the participants understand the importance of halal certification, and 87% understand the required documents in the application process. With the implementation of this activity, it is expected that 100% of the food products from UMKM in Melung Tourism Village will obtain halal certification, thereby enhancing the competitiveness of their products.

Saat ini, Computer Aided Diagnosis (CAD) tengah dikembangkan secara masif sebagai second opinion reader di berbagai modalitas pencitraan medis, salah satunya ultrasonografi (USG). Untuk skrining otomatis citra USG yang banyak, berulang-ulang dan terus-menerus, teknik deteksi objek memainkan peran krusial pada sistem CAD. Deteksi objek kanker pada citra USG tidak mudah karena objek-objek tersebut berkontras rendah dan bertepi kabur akibat gangguan derau speckle dan artifak. Studi ini mengatasi tantangan ini dengan mengusulkan metode deteksi berbasis model active-contour Chan-Vese (CV) tersimplifikasi diikuti operasi morfologi. Adapun performa kuantitatif diperoleh menggunakan skor Intersection of Union (IoU) antara objek-objek terdeteksi dengan ground truth-nya. Usulan metode divalidasi menggunakan 20 citra USG tiroid dan payudara dengan hasil rerata skor IoU mencapai 92,36%. Performa yang menjanjikan ini menunjukkan bahwa usulan metode layak diimplementasikan pada sistem CAD.

The use of standard AC and fluorescent lamps tends to be more wasteful. Based on observations, building C uses standard AC with a capacity that does not match the needs of the room and uses fluorescent lamps with minimal lighting intensity, so it is necessary to conserve energy to obtain opportunities for saving electrical energy while still paying attention to environmentally friendly aspects and occupant comfort. Electrical energy saving analysis is carried out through an energy audit by calculating the Energy Consumption Intensity (IKE). The pur-pose of this study is to obtain opportunities for saving electrical energy through energy conservation. Calculation of IKE values in 2019 and 2020 in building C is in the efficient category. Opportunities to save energy are carried out by replacing standard AC with low watt AC or inverter AC, resulting in savings of 28% and 30,6% with payback periods of 2,9 years and 3,8 years. Turning off the AC 15 minutes and 30 minutes before the end of working hours resulted in savings of 2,8% and 5,7% on standard AC, 2,9% and 5,8% on low watt AC and inverter AC. Energy saving opportunities by replacing fluorescent lamps with LED lamps obtained savings of 16,28% with a payback period of 4,4 years and the lighting intensity has met SNI with lighting intensity of 358-421 lux in the working room and 315-361 lux in the meeting room.
