Abstract. Fish silage is a liquid product from fish by product preserved in acid, and could potentially be used as feedstuff. The fish sialge can be produced through both biological andchemical methods, however to date the the quality of result was low, therefore this study was crucially needed. The research objective was to acquire the right method to improve the nutritional quality of fish silage and produce cheap fish feed ingredients. The factorial completely randomized design was used in the study. The first treatment was the effect of various types of organic acids (formic acid, propionic acid, benzoic acid, sorbic acid, citric acid, acetic acid) and LAB (Lactobacillus casei) to fish silage quality. The second treatment was the effect fermentation time (3, 7 and 14 days) to fish silage quality. The results showed that the highest protein content (45.95%) was occured on treatment using L. casei with fermentation time of 14 days. The highest fat content (5.87%) wasfound on treatment using L. casei with fermentation time of 14 days. In addition, the lower protein content (30.02%) is occured on treatment using propionic acid with fermentation time of 3 days, while the lowest fat content (4.77%) was occured on treatment using benzoic acid with fermentation time of 3 days. It was concluded that the best quality of fish silage was occured on treatment using L. casei with fermentation time of 14 days.Keywords : fish silage; organic acid; LAB Abstrak.

This paper discusses a door lock automation system using IoT-based e-KTP that will be monitored using a smartphone. The system consists of HC-SR04 ultrasonic sensor, Radio Frequency Identification (RFID), and EasyVR 3. HC-SR04 ultrasonic is used to detect the presence of door access users. The RFID sensor is a medium for entering the access code in the form of Unique Identification (UID), and the EasyVR 3 sensor is used to detect passwords in the form of voice signals from access users. To record the real-time of door access users, Real Time Clock DS3231 is used. The microcontroller used to manage the system's work is Arduino Mega 2560. NodeMCU ESP 8266 sends data to a smartphone as a monitoring device. MG90S servo is used to drive the door opening/closing mechanical system. To get access, users must register by entering e-KTP UID data and passwords as sound signals. Testing is carried out to evaluate the performance of the system that has been made. The test scenarios consist of door access from the inside and door access from the outside, each for users who have access and those who do not have access. The test results show that the system can secure door access only for users with access. Monitoring the system using a smartphone can work well where every instance of access use can be monitored user data and access time. However, there are still weaknesses in the mechanical part of opening / closing the door where the servo fails to open and close.

This paper discusses the single-axis solar concentrator tracker system for solar thermal power plants. This system concentrates the harvesting of heat from solar radiation to increase the electrical power generated from the solar thermal conversion process. The solar concentrator is designed as a parabola and can adjust the direction following the sun's motion. The overall system work is regulated by Arduino Mega 2560. A 24-volt DC motor and BTS7690 driver are used to drive the parabola. RTC DS3231 is used to provide real-time data. ACS712 sensor is used to measure the current and voltage generated. The conversion of solar heat into electrical energy is done using Peltier SP1848. All generated data is recorded to the SD Card module, which will later be used to analyze the overall system performance. The tracker system is designed to move following the sun’s position, starting from 08:00 at position 19O to 17:00 at position 139O. Update the position or direction of the parabola to 15O, done every hour. The effectiveness of the tracker is assessed by comparing the solar concentrator system that is not equipped with a tracker. From the tests conducted for two consecutive days, the tracker-equipped solar concentrator system produced an average percent increase in electrical power of 4.86% on the first day and 5.26% on the second day. The average percent increase in power for two days was 5.06%. The results show that the application of the tracker is able to increase the productivity of the solar thermal power generation system. This opens up opportunities for larger-scale deployment in solar concentrator farms.

The Batu city government is committed to developing halal tourism, especially in meeting the needs of halal food for Muslim tourists. Food that comes from slaughtered animals has a halal critical point that needs to be considered in order to ensure the health and inner peace of the community when consuming meat by providing ASUH meat. Having a certified halal slaughterer and authorized officers to carry out antemortem and postmortem inspections is necessary as a form of consumer protection and implementing halal tourism in Batu City. Training assistance activities were carried out to find the right model for optimizing the competency certification of halal slaughterhouse officers at poultry slaughterhouses in Batu city. This research uses a quantitative descriptive research design and partial least squares (PLS). The results of the research show that before assistance was provided, respondents had low knowledge and abilities regarding the 13 SKKNI competency units so that the halal standards for slaughtered animals were not met, whereas after assistance was provided, respondents met slaughter standards so that the results of their slaughter could be categorized as halal and toyibban and consumers would be protected as halal. Appropriate training and certification is carried out for 7 days, 56 hours of learning and 13 competency units. Effective learning for respondents is at 13.00—17.00 WIB and continued with field practice at the RPA at 19.30—22.00 WIB respectively by applying the one day one competency learning model.

Menyiram tanaman adalah salah satu kegiatan yang sering dilakukan didalam kehidupan sehari-hari, dan terkadang dengan kesibukanpekerjaan kita sehari-hari, kita tidak sempat menyiram tanaman tersebut,sehingga tanaman akan layu atau bahkan mati. Untuk mengatasi masalah tersebut perlu adanya sistem kontrol otomatis, dengan cara membuat sistem penyiraman secara otomatis. Saat sistem dijalankan, sensor kelembaban tanah akan mendeteksi kondisi tanah, Jika kondisi tanah kering kelembaban < 20 % maka motor servo akan bergerak On (menarik tuas kran menjadi open). Dan data berupa angka dari arduino akan di salurkan ke ModulGprs , dan modul Gprs akan mengirimkan SMS berupa teks dan angka ke user/pengguna. Jika kondisi tanah tidak kering dan kelembaban > 50% atau lembab maka motor servo berputar terbalik(menarik tuas kran menjadi closed) sehingga kran air akan menutup atau mati. Dengan terciptanya alat ini kita sudah tidak lagi repot untuk menyiram tanaman secara manual lagi, karena alat ini akan beroprasi secara otomatis,dan juga bias menghemat waktu dan biaya

Gas LPG (Liquefied Petroleum Gas) pada saat ini memang sangat membantu dalam kehidupan masyarakat, jauh lebih baik dari pada menggunakan minyak tanah. Seperti namanya, gas LPG, berwujud gas jauh lebih hemat daripada minyak tanah yang berwujud cair. Namun dimana ada kelebihan pasti ada kekurangan, karena berwujud gas, otomatis tidak dapat dilihat dengan mata telanjang. Jika terjadi kebocoran maka akan sangat membahayakan. Alat ini bertujuan untuk mencegah kebakaran disebuah gedung atau rumah karena kebocoran gas. Oleh karena itu penulis tertarik untuk merancang alat pendeteksi kebocoran gas berbasis IOT. Menggunakan NodeMCU ESP8266 sebagai control utamanya, ditambah dengan sensor MQ-2 sebagai masukan dan buzzer sebagai keluaran. Alat ini berbasis IOT (Internet Of Things)sehingga apabila terjadi kebocoran gas, akan ada notifikasi jarak jauh melalui smartphone. Hasil pengujian untuk jarak yang ideal yaitu satu 1 cm dari regulator tabung akan menghasilkan respon 0.90 detik dan respon alat ke smartphone sebesar 2.74 detik.
