Fish has two chemical sensory/receptor systems that smell (olfactory) and taste (gustatory) odor that adapt to the specific substance of the environment. In general, olfactory is similar to nasal organs for human nostrils. The olfactory receptors detect chemical stimuli in the form of electrical signals. Based on the ability of fish that can respond to chemical stimuli through the sense of smell, a substance can be used to attract the attention of fish. In response to this reality, AFA (Amino Acid Fish Aggregation) can be developed as a fish collecting tool to attract fish bu using amino acid preparation that works though the sense of smell and taste of fish. The objectives of this study were to design and produce a prototype of Amino Acid Fish Aggregation (AFA), to determine the productivity of catches of raft lift net by using AFA, and to calculate the length of the weight of the catch using AFA. The data used were catch data with weights and lengths of fish catch by raft lift net using AFA. The results showed that the AFA prototype which had a size of p x l x t : 35 x 22 x 15 cm and the highest catches was found at 18.00-00.00 WIB by using AFA with raft lift net. The catches using AFA in Palabuhanratu waters amounted to 5 types of fish, namely stolephorus sp., sardinella sp., rastrelliger kanagurta, euthynnus affinis, trichiurus sp., and positive allometrics were found in rastrelliger kanagurta and anchovy, but negative allometrics were found in euthynnus affinis, sardinella sp., and trichiurus sp.

We has been successfully creating a laboratory security system prototype based on Arduino Mega. This device assisted with PIR sensor (passive infrared) and RFID (Radio Frequency Identifier). In experiments carried out study the sensitivity of the PIR sensor at a distance of 0 meters, 0.5 meters, 1 meters, 1.5 meters, 2 meters, 2.5 meters, 3 meters, 3.5 meters and 4 meters then at an angle of 00, 300, 450, and 600 with the source of motion is the humanâ€™s body movement. In this study data showed that at a distance of 2 .5 meters at an angle of 60 degrees PIR was not able to catch the source of human movement. At a distance of 2.5 meters below and 60 degrees could not catch the source of human movement. Otherwise at a distance more than 2.5 meters human movement can not be captured by the PIR sensor. At the RFID trial data obtained that the card can be read by an RFID reader within a maximum of 3 cm, with no barrier between the RFID reader and the card. The data condition also occurs when a thick paper is placed between the card and RFID reader as a barrier. While at the moment given the barrier is made from plastic the card can be read at a distance of 1 cm maximum.

We have been successfully to create a Control System Temperature and Air Humidy Monitoring Room Based on Arduino Uno with DHT22 Sensor and Passive Infrared (PIR). DHT22 Sensor be used as a measurement of temperature and air humidity in the room and Passive Infrared Sensor as a tool of detection the movement of people in a room. In this experiment, carried out tests of the DHT22 sensor and digital thermometer with a type AZ-HT-02 to room temperature with a hot air given through a hairdryer for 3 minutes with a span of per 10 seconds. In this test, the obtained data is that the room temperature is which measured by DHT22 sensor have an average difference of 0.93 against digital thermometer (as a calibration). In this test also obtained DHT22 sensor more sensitive Rrelative Humidity (RH), this is caused when given the hot air, humidity measured more rapid adjustment and yet different with digital temperature was slow to adjust air humidity in the room. This device using an Arduino Uno board, a Liquid Crystal Display (LCD) module and Real Time Clock (RTC) as a display of the temperature and air humidity in real time. This device is connected to a fan that can stabilize the room temperature are considered less convient to do activities in the room.

The research focuses on implementing an automatic door lock system based on face recognition using the ESP32-Cam microcontroller and integrating it with the Telegram platform. The system is designed to enhance security at Proactive Robotic by leveraging IoT technology for office door access control. System design began with needs analysis and identification of existing security issues which do not integrate with other smart home systems at the institution. Development methods included hardware and software design, circuit schematic creation, PCB production, and physical assembly. System testing ensured facial detection, recognition, and essential solenoid operation in varying lighting conditions. Test results showed the system accurately recognizes registered faces under standard lighting, automatically unlocks doors, and sends real-time notifications via Telegram. However, system accuracy under low-light conditions needs improvement, as well as enhanced user data security to protect stored information privacy. This research contributes to developing IoT and face recognition-based security applications. The system successfully implements cutting-edge technology to improve physical security and access management in office environments, laying the foundation for future advancements in security technology.

Mass Rearing of Foliar Nematode Aphlenchoides fragariae on Fungal Culture This research investigated the in vitro cultivation of the foliar nematode Aphelenchoides fragariae, which can feed on both plants and fungi. As there was no prior information available in Indonesia, this study aimed to establish an efficient method for mass rearing, thereby supporting future research. Five fungal cultures i.e. Alternaria porri, Fusarium oxysporum, Botrytis cinerea, Pythium sp., and Rhizopus sp. grown in potato dextrose agar were evaluated as potential growing media at three different temperatures: 16, 28, and 37 ℃. Nematodes were surface-sterilized with streptomycin sulfat 0.1% before being introduced into the fungal cultures. Results showed that A. porri was the most favourable culture for A. fragariae reproduction, particularly at 28 ℃. Under these conditions, the average final population reached 407.8 nematodes per petri dish. Notably, A. fragariae failed to thrive at 37 ℃ in all tested fungal media. This suggests that the optimal temperature for its reproduction ranges between 16 and 28 ℃. This study provides valuable insights into the in vitro cultivation of A. fragariae, paving the way for further research utilizing this nematode species.

Tanaman Song of India (Dracaena reflexa) merupakan komoditas ekspor Indonesia dengan tujuan Jepang, Malaysia, Korea Selatan, Singapura dan Eropa. Ditemukannya nematoda pelubang akar Radopholus similis pada medium tanam kokopit menyebabkan dikeluarkannya Notification of Non-Compliance (NNC) oleh negara tujuan. Penelitian ini bertujuan mengekplorasi penggunaan teknik Direct Electric System (DES) untuk mengeliminasi nematoda pelubang akar R. similis yang ditemukan pada medium tanam kokopit. Percobaan laboratorium dilakukan untuk mengevaluasi efek penggunakan DES pada berbagai tegangan, jarak elektroda dan lama pemaparan pada medium tanah dan kokpit terhadap mortalitas R. similis. Percobaan rumah kaca dilakukan untuk mengetahui pengaruh DES terhadap mortalitas R. similis dan pertumbuhan tanaman D. reflexa. Hasil penelitian menunjukkan bahwa pada medium tanah dan kokopit kematian nematoda berturut-turut sebesar 83.46% dan 86.17% tercapai dengan tegangan DES 1500 V, serta jarak elektroda 1 dan 2 cm selama 15 menit. Perlakuan DES pada tegangan 1500 V selama 15 menit pada medium kokopit tidak menurunkan pertumbuhan D. reflexa di rumah kaca.
