Abstract

CV Icommits masih melakukan presensi yang tergolong konvensional dengan cara mengisi daftar hadir oleh pegawai pada formulir presensi yang sudah disediakan di perusahaan. Presensi seperti diatas dapat menyebabkan proses presensi dinilai kurang efektif karena cara tersebut rentan terjadinya manipulasi data kehadiran seseorang yang disebabkan human error. Oleh karena itu, peneliti memberikan suatu solusi yakni dengan merancang teknologi informasi melalui sistem informasi presensi pegawai berbasis web yang terintegrasi dengan Radio Frequency Identification (RFID) reader dan kartu RFID yang dirasa mampu menyelesaikan permasalahan karena dapat mempermudah proses presensi pegawai dan menghasilkan data yang real-time. Adapun metode yang digunakan dalam analisis dan perancangan sistem ini adalah menggunakan pemodelan UML (Unified Modeling Language). Hasil akhirnya berupa perancangan dan implementasi sistem informasi presensi dengan integrasi RFID dapat mengontrol presentase data kehadiran dan ketidakhadiran setiap pegawai dalam bentuk chart/diagram serta fitur kelola data rekapitulasi presensi pegawai yang dapat mempermudah pemilik perusahaan dalam memonitoring ketercapaian jam kerja pegawai on site.

Abstract

Cijambe district is a famous area for fish farming. The group of tilapia and carp farmers consists of 50 people, and each of them has 10 to 12 ponds. The problem is that the conventional feeding system requires a lot of time and schedule uncertainty. As a result, problems arise in the fish’s growth and size. On the other hand, too much feed causes high production costs. The solution offered is by applying an automatic fish feeder (AFF) solar cell-based.  The AFF is capable of providing fish feed periodically, three times a day. The feeding schedule is set at 07.00, 12.00, and 16.00. The purpose of this service program is to increase the production of fish farmers in Cijambe village through AFF technology using solar cells.  The method used is identifying the needs of fish farmers, designing AFF tools, manufacturing AFF, operational assistance training of using and maintenance of AFF, and the output of the program. The results of the community service activities were an increase in feeding efficiency from 69.4% to 86.8%, an increase in knowledge and skills about AFF from the fish farmers group at 70%, and an increase in carp production capacity from 5 tons per month to 8 tons, and tilapia from 15 tons per month to 24 tons or an increase in production capacity of 60%.  ---  Kecamatan Cijambe merupakan daerah yang terkenal dengan budidaya ikan. Sebanyak 50 peternak sebagai kelompok peternak ikan yang masing – masing memiliki kolam 10 hingga 12 kolam. Permasalahan yang dihadapi peternak ikan adalah pemberian pakan ikan yang dilakukan secara manual sehingga dibutuhkan waktu yang banyak dan jadwal ketidakpastian pemberian pakan berdampak pada pertumbuhan dan ukuran ikan. Di samping itu, terlalu banyak pemberian pakan menyebabkan tingginya biaya produksi. Solusi yang ditawarkan yaitu dengan menerapkan teknologi alat pakan ikan otomatis/Automatic Fish Feeder (AFF)berbasis  solar cell. AFF tersebut mampu memberikan pakan ikan secara otomatis secara periodik, tiga kali sehari. Jadwal pemberian pakan di atur pada pukul 07.00, 12.00 dan 16.00. Tujuan program pengabdian ini adalah untuk meningkatkan produksi kelompok peternak ikan desa Cijambe melalui teknologi alat pakan ikan otomatis menggunakan solar cell. Metode pengabdian yang dilakukan yaitu identifikasi kebutuhan peternak ikan, desain alat pakan ikan otomatis, pembuatan alat pakan ikan otomatis, pendampingan operasional pelatihan penggunaan dan pemeliharaan alat pakan ikan otomatis, dan output program pengabdian. Hasil kegiatan pengabdian yaitu terjadi peningkatan efisiensi pemberian pakan dari 69,4% menjadi 86,8%, terjadi peningkatan pengetahuan dan keterampilan tentang AFF dari kelompok peternak ikan sebesar 70% dan peningkatan kapasitas produksi ikan mas dari 5 ton per bulan menjadi 8 ton, dan ikan nila dari 15 ton per bulan menjadi 24 ton atau terjadi peningkatan kapasitas produksi sebesar  60%.

Abstract

Feed is the single largest cost component in Nile tilapia aquaculture, frequently accounting for more than sixty percent of total production costs. However, in most Indonesian smallholder operations, feed is still dispensed manually based on visual estimation. Existing Internet of Things feeders reported in the literature generally automate the timing of feed delivery but do not provide feedback on the actual amount of feed dispensed. They are also rarely evaluated in a Recirculating Aquaculture System, where uneaten feed increases the load on the biofilter. This study addresses this limitation by designing, implementing, and experimentally evaluating an Internet of Things based automatic feeder with closed loop gravimetric dosing integrated into a Recirculating Aquaculture System for Nile tilapia culture. The system combines an ESP32 microcontroller, a load cell sensor, a servo actuated feed gate, a BTS7960 controlled direct current auger, and a real time clock scheduling module. A web based interface enables real time adjustment of feed ration and feeding schedule. The feeder was evaluated over ten dispensing cycles using a target ration of fifty grams, and its performance was compared with manual feeding during a rearing trial. Gravimetric dosing achieved an average error of two point four percent and an average dosing accuracy of ninety seven point six percent, with an average deviation of one point two grams per feeding cycle. During the rearing trial, the experimental group consumed twelve kilograms of feed, whereas the control group consumed fourteen kilograms, representing a feed reduction of fourteen point three percent. The experimental group also achieved a feed conversion ratio of one point four six, compared with two point zero zero in the control group. Survival reached ninety two point five percent in the experimental group and eighty one percent in the control group. Mean individual body weight increased from two hundred forty five grams in the control group to two hundred eighty grams in the experimental group. Size uniformity also improved, with the coefficient of variation decreasing from fifteen percent to eight percent. These findings demonstrate that integrating gravimetric feedback into an Internet of Things based feeder provides measurable feed savings beyond scheduling automation alone and offers a practical and appropriate technology solution for small scale Nile tilapia production in Recirculating Aquaculture Systems.

Abstract

The potential of Sidajaya Tourism Village, which is not yet known to many people, has hampered the development of this tourist village. Information about the Sidajaya tourist village is still difficult to access, making people reluctant to look for the information they need, so knowledge about it is limited. Therefore, a system is needed to help the public access information about the Sidajaya tourist village. This research aims to build a website-based Sidajaya Tourism Village Information System as a medium for information and promotion. This system was built using the PHP programming language and MySQL database, with data collection methods through observation and interviews. The system development stage includes analysis, design, implementation, and testing. The result of developing this system is a website that allows the public to search for information about the Sidajaya tourist village easily and supports more efficient promotion and management to increase tourist visits.
