ABSTRAKPanel surya merupakan energi terbarukan yang menjadi solusi untuk masa depan. Tetapi efisiensi menjadi masalah tersendiri pada panel surya, dengan efisiensi yang rendah mengakibatkan daya yang dihasilkan kecil dan tidak sebanding dengan harga yang dikeluarkan. Pada penelitian ini dilakukan perancangan untuk meningkatkan efisiensi panel surya ke titik maksimal dengan berbagai fitur yaitu sistem tracking, cermin reflector dan monitoring IoT. Sistem ini menggunakan sensor Light Dependent Resistor (LDR) yang digunakan untuk mendeteksi intensitas cahaya dan dilengkapi juga motor penggerak untuk mengatur sudut elevasi, cermin reflector sebagai pemantul cahaya, dan IoT untuk monitoring jarak jauh. Hasil penelitian menunjukkan bahwa penggunaan cermin reflector mampu meningkatkan daya pada siang hari tetapi turun ketika pagi dan sore hari, sedangkan sistem tracking mampu memproduksi daya lebih baik pada waktu kapanpun.Kata kunci: panel surya, sensor, reflektor ABSTRACTSolar panels are renewable energy which is the solution for the future. But efficiency is a problem in solar panels, with low efficiency resulting in small power generated and not worth the price incurred. In this research, the design is carried out to increase the efficiency of solar panels to the maximum point with various features, namely the tracking system, mirror reflector, and IoT monitoring. This system uses an LDR sensor that is used to detect light intensity and is also equipped with a motor to adjust the elevation angle, reflector mirror as a reflection of light, and IoT for remote monitoring. The results showed that the use of reflector mirrors can increase power during the day but go down in the morning and evening, while the tracking system is able to produce better power at any time.

The purpose of this study is to determine the form of construction work contracts and the legal consequences of construction work contracts that are not in accordance with the provisions of statutory regulations in the field of construction services. The legal research method used is normative legal research, which is a study of the prevailing laws and regulations which are particularly related to construction service contracts. This type of research is legal obscurity. A construction work contract is a type of formal agreement in which Law Number 2 of 2017 concerning Construction Services and its implementing regulations determines the procedures and conditions before the contract is made, including the form and content of the construction work contract, by determining the standard at a minimum, the contents of a construction service work contract that must be included in the construction work agreement by the parties. Since the construction work contract is a contract with mandatory conditions, the construction work contract is a formal agreement. This is if the construction work contract is made without paying attention to the provisions of laws and regulations in the field of construction services, both regarding the qualification requirements of a construction service provider, the procedure for selecting a service provider and the form and content of the construction service contract that has been determined by the law. As a juridical consequence, if the formal conditions are not fulfilled in a contract concerned, it is not legally enforceable or in other words it is a null and void contract (nietig, null and void).

The level of coconut maturity can be determined by not only observing its shell color but also by applying audio recognition approach from knocking on coconut shell. This knocking sound distinguishes young, fairly mature, and mature coconut. Recognizing the sound characteristic of knocking on coconut is usually performed by the skilled ones who are having extensive experiences and sound sensitiveness of coconut knocking. In order to substitute the skilled ones, the design of coconut maturity prediction device with acoustic frequency detection is invented. The coconut sound signal is tapped by stethoscope which is connected to MAX9814 noise sensor. Arduino Due micro-controller is used to process the signal. The process in processing the signal consists of: conversing analog signal to digital, screening the signal, and finding the average value of sound signal frequency spectrum. The signal screening uses bandpass digital filter, type IIR (Infinite Impulse Response) Elliptic order 7. This filter is utilized in order that the signal that is being processed is not some noise but the signal of knocking sound on coconut. The calculation of average value of sound signal frequency spectrum uses FFT (Fast Fourier Transform) analysis. The maturity prediction is carried out using the classification method of Naive Bayes. The input is three average value of knocking sound frequency and coconut size, and the output is classification of coconut maturity. From this research, it is generated 80% of system success rate.

The sea has many potentials to be utilized based on the ecological aspects of coastal area. Almost in the coastal areas and islands in Madura are experiencing difficulties in utilizing marine resources. Salinity changes influenced by water osmotic pressure whereas biota living in salt water should be able to adjust the osmotic pressure from its environment. The changes in pH have an effect on the survival of marine organisms as not all saltwater creatures survive with the change of it. From these problems a system of "Designing Measure of Salt Measure and Sea Water pH Using Fuzzy Logic Based Android" is made. Where measuring system is made to prioritize the level of accuracy of changes in salinity and pH value of sea water. So that people could exploit the sea potential based on the condition of the sea water.

Facial expressions are one of the ways humans communicate to convey one's emotions to their communication partner nonverbally. Therefore, human facial expressions can be used for various purposes, one of which is knowing customer satisfaction. So far, customers of Bank Rakyat Indonesia (BRI) provide feedback on service quality using only a polling system, namely by filling out a criticism and suggestion form and then entering it in a suggestion box which is distinguished between satisfied and dissatisfied. However, such a method is less effective because it can be easily manipulated by customers and customers are often indifferent to the feedback. So that the improvement of service quality tends to be less effective. This research will design a system that can recognize human facial expressions to determine the level of customer satisfaction with input data in the form of video data taken by a webcam camera with the viola-jones method to detect faces and determine facial patterns. Then the facial data will be classified using the K-Nearest Neighbor method to determine the type of facial expression. Determination of the value of k will determine the success rate of facial expression detection. The processed data will be displayed on a liquid crystal display (LCD) and then stored in a MySQL database. The results showed that the accuracy of facial expression detection was 80.77% from 52 facial expression data.
