Abstract

Tanaman padi merupakan penyumbang produksi padi yang signifikan dan menjadi sumber pangan utama di Indonesia. Dengan meningkatnya hasil panen padi, permasalahan limbah tanaman padi, khususnya jerami padi, menjadi semakin menonjol. Limbah jerami padi sering dibakar setelah panen padi, sehingga menyebabkan pelepasan gas dan partikel beracun ke udara, menyebabkan polusi udara dan menimbulkan masalah kesehatan masyarakat. Selain itu, sebagian besar proses pengolahan biji-bijian masih mengandalkan mesin diesel berbahan bakar minyak. Penelitian ini bertujuan untuk memanfaatkan potensi biogas dari limbah jerami padi melalui fermentasi anaerobik dengan menggunakan perhitungan matematis. Selanjutnya dilakukan analisa terhadap potensi energi listrik yang dapat dihasilkan serta kajian terhadap biaya-biaya yang terkait dengan berbagai komponen pemanfaatan biogas. Hasil penelitian menunjukkan bahwa 4.800.000 kg limbah jerami padi per tahun dapat menghasilkan potensi biogas sebesar 576.000 m³/tahun. Potensi energi listrik sebesar 3.513.600 kWh/tahun cukup untuk mengoperasikan pabrik biogas sebagai pembangkit energi listrik untuk operasional pengolahan gabah di Desa Koto Laweh, beroperasi 12 jam setiap hari dan menghasilkan total energi listrik sebesar 240 kWh. Proses ini melibatkan penggunaan 960 kg limbah jerami padi dan tambahan 6,5 kg urea. Perkiraan biaya komponen pemanfaatan limbah jerami padi mencapai Rp. 112.318.925, menunjukkan potensi penghematan biaya yang signifikan dibandingkan sumber bahan bakar konvensional.Kata kunci: anaerob, jerami padi, biogas, listrik

Abstract

Biological cells has natural characteristic to isolate subtances between outside and inside cell by using its membranes. By applying pulsed electric field, membrane pores can be formed that facilitates the introduction of small foreign materials into cells. The success of this technique can be determined by observation of conductivity changes. The equivalent conductance can be measured but the unhomogeneous electric field results unhomogeneous conductance. The aim of this research is to compute conductivity distribution on a specific biological tissue (e.g. mammalian muscle tissue) that being electrically pulsed. The tissue is modeled as conductive medium due to its conductivity dominant. The medium as a system of electrocondusive, modeling of this system leads to get a model in the form of partial different equation problems. A finite element method is used as a tool to solve the problem. The final simulation result are graphical presentations showing the conductance. It is also shown that the intensity of the field is higher in the location near electrode and smaller in remote location. Then, electrical conductivity, derived from electric field exposure is then can be computed. It is shown that needle electrodes exibit inhomogeneous conductivity distribution. A large increase of conductivity occurs surrounding both electrodes and much smaller increase on other location. A larger conductivity change means more number and size of pores are produced. In practical aspect, the result can be further developed for designing in-vivo pulsed electric field applications

Abstract

Increasing population and consumption patterns affect the volume, type, and characteristics of waste which vary and increase periodically. This increment must be accompanied by the management of waste transportation so that the accumulation of waste can be prevented. Therefore, it is necessary to design a prototype of a smart dustbin condition monitoring tool that is capable of providing full information and notifying the collector in the form of the location of the IoT-based dustbin. The research method is a prototyping type to obtain a smart dustbin prototype and produces IoT-based smart dustbin hardware and software. Ultrasonic sensors are used to detect objects and measure the height of waste, loadcell sensor measure the weight of waste, and GPS is used to obtain the location of dustbin. NodeMCU ESP8266 processes sensor data and sends it to the user. The results showed that testing of the object detection hardware was able to open and close the dustbin automatically when there was an object at a distance of ≤50 cm. Detectors of height and weight of waste can measure the height and weight of waste with an error of 0.4% and 0.15% respectively. The results of software testing show that the tool succeeds in sending WhatsApp notification data when the waste height reaches 3 cm from the sensor or 4000-gram waste weight, with a Throughput measurement of 327.95 kbps, and takes 2.61 seconds to send a notification message of 69 bytes.

Abstract

Gangsa is a traditional jam musical instrument from Bali that has ten tone blades. This tool is played by hitting the blade and touching it for muted. This tool is quite expensive because of the materials and elements of art in it. In this study, designed and built a prototype of a modern and cheaper musical instrument for the needs of learning media. The prototype is designed to have a piezo-electric sensor connected to an Arduino Pro-mini as an input signal. This signal then passes the play threshold value as a determinant of whether the tone on a bar is played or not. The tone on each bar is stored on an SD-card with a PCM wav format of 12,000 kHz, 8 bits, mono. The next step after playing the bar tone is damping using a touch sensor. The sensor is designed using a darlington circuit and is connected to an Arduino as a tone-damping signal. The method is able to produce sound with good quality, but only for one bar. After playing the 5th bar, the quality of the resulting sound decreases even more. For that, a series of mixers is added for better and louder sound quality

Abstract

Television is one of the most widely used media for receiving sound and image transmissions worldwide, particularly in Indonesia. Government regulations require all television broadcasters in Indonesia to cease analog broadcasts and transition to digital broadcasts. Consequently, a device known as the Set Top Box (STB), equipped with a low noise amplifier (LNA), converts DVB-T2 digital signals into images and audio suitable for analog televisions. Tests were conducted to evaluate its signal reception capabilities. These tests took place at four Palembang city locations, utilizing indoor and outdoor antennas. The results revealed that the device's signal strength ranged from -48.7 dBm, reaching 100% signal quality, to the weakest signal at -97 dBm. Moreover, an average difference of 6.9 dB was observed between indoor and outdoor testing for each frequency. Furthermore, analyzing the average signal strength based on distance showed that the highest strength of -56.2 dBm occurred at a distance of 1.5 km from the transmitter during outdoor testing. In comparison, the weakest strength of -91.6 dBm occurred at a distance of 1.8 km during indoor testing. Additionally, a signal strength comparison between test locations indicated that the most significant difference was between the Kamboja and Plaju locations. The LNA device achieved its highest gain value of 15.2 dB. Various factors, including antenna direction, obstructions such as buildings, antenna height, signal stability, and the distance between the transmitter and receiver, influence the signal quality.

Abstract

A library is a building or room designed for the purpose of storing and organizing various types of library items, including books, monographs, serial publications, brochures, and non-library materials. In the Hasanuddin University (Unhas) library, there are at least 516,000 volumes of literature. One of the important things is how to ensure that the contents of the library remain relevant to the special literacy needs of this modern era. Considering that books are static, of course it is necessary to update and procure the newest and most up-to-date types of books. The goal of this research is to use the TOPSIS algorithm to determine the procurement and updating of books in the UNHAS library, particularly at the Faculty of Nursing. Based on the regular year data criteria (2008–2023), it is known that books borrowed (5–25≤ ) and book stocks (5–45 copies) are based on the publication every five years. It is known that if the preference value (v) 0.60 is included in the procurement category, preference (v) 0.30 is included in the updating category, and preference (v) 0.31–0.59 is not included in the procurement and update categories. The ranking results of 6 (six) book samples reveal that 2 (two) categorized into the procurement category with a preference value (v) of 0.64, 2 (two) categorized into the updating category with a preference value (v) of 0.2 and 0.3, and 2 (two) categorized into the category where book updates and procurement do not occur, with preference values (v) of 0.36 and 0.5.
