Abstract

LoRa merupakan teknologi komunikasi yang populer dalam aplikasi IoT karena jangkauan hingga 15 km dan konsumsi daya rendah. Teknologi ini telah digunakan di berbagai negara, termasuk Indonesia, karena efisiensi energi dan biaya. Namun, penggunaannya tidak selalu sesuai dengan regulasi frekuensi tiap negara. Sebagian besar perangkat LoRa yang beredar di pasaran bekerja pada frekuensi 433 MHz, 868 MHz, dan 915 MHz. Hal tersebut berbeda dengan regulasi frekuensi LoRa di Indonesia, yang mengharuskan perangkat LPWA (Low Power Wide Area) non seluler beroperasi pada rentang frekuensi 920–923 MHz sesuai dengan Peraturan Direktur Jendral Sumber Daya dan Perangkat Pos dan Informatika No 3 Tahun 2019. Untuk mendukung hal ini, diperlukan pengembangan antena yang sesuai. Penelitian ini bertujuan untuk merancang, mensimulasikan, dan merealisasikan antena mikrostrip patch rectangular array yang bekerja pada frekuensi 920-923 Mhz untuk komunikasi LoRa. Antena dirancang menggunakan metode konfigurasi array dengan empat elemen peradiasi guna meningkatkan gain dan performa antena. Simulasi dilakukan menggunakan CST Studio Suite 2019 untuk memprediksi performa antena. Hasil simulasi menunjukkan VSWR 1.3681, return loss -16.169 dB, gain 4.015 dBi, dan bandwidth 3 Mhz. Hasil pengukuran menunjukkan bahwa VSWR 3.2521, return loss -5.5338 dB, gain 6.298 dBi, sedangkan bandwidth tidak dapat dihitung karena VSWR lebih dari 2. Pola radiasi di bidang elevasi menunjukkan bahwa hasil simulasi mendekati bentuk unidirectional, sedangkan hasil pengukuran menunjukkan bentuk omnidirectional. Pada bidang azimuth, simulasi menunjukkan pola bidirectional, sementara pengukuran memperlihatkan pola omnidirectional. Meskipun antena berhasil meningkatkan gain secara signifikan, terdapat perbedaan parameter antara hasil perhitungan, simulasi, dan pengukuran.

Abstract

This study aims to determine the types of epiphytic plants found in oil palm plantations in Kakullasan Village, Tommo District, Mamuju Regency, West Sulawesi. Sampling was conducted using the exploration method, namely exploring the predetermined location using 4 plots measuring 10x10 m, then taking samples found and recording the condition of the location or place where the epiphytic plants grow. From the results of the study, ferns (Pteridophyta) were found and no moss (Bryophyta) was found. The total number of ferns from each plot was 88 consisting of 9 types of species divided into 5 classes of ferns, namely Pteridopsida, Filicopsida, Polypodiopsida, Filicinae and Gleicheniopsida. For the Pteridopsida class, 3 types of species were found, namely Drynaria quercifolia, Phymatosorus scolopendria and Nephrolepis exalata. The Filicopsida class found the species Dryopteris filix-mas and the Polypodiopsida class found the species Vittaria lineata. Filicinae class found 3 types of species, namely Asplenium nidus, Davalia solida and Davalia denticulate. Gleicheniopsida class found 1 type of species, namely Gleichenia linearis. The dominance index ranges between 0.002 - 0.023 which means that no species dominates because none of them are close to the value of 1, while the species diversity index is classified as high because the diversity index value is H’ = 1.206 or greater than 1 (H>1)

Abstract

The Academic Information System (SIAKAD) serves a pivotal function in enhancing both operational efficiency and the quality of academic services within higher education institutions, particularly amidst the accelerating shift toward digitalization in the education sector. Despite its strategic importance, the effectiveness of SIAKAD implementation is contingent upon the level of user satisfaction—most notably that of students—which remains insufficiently explored through analytical models capable of capturing intricate causal relationships. This study seeks to empirically examine the determinants of student satisfaction in utilizing SIAKAD by investigating the influence of system quality, information quality, and ease of use, with perceived usefulness positioned as a mediating construct. The research adopts the Partial Least Squares Structural Equation Modeling (PLS-SEM) approach, which is methodologically appropriate for complex models involving latent variables and non-normally distributed data. The analysis is based on survey data collected from 128 active undergraduate students at Universitas Patompo. The empirical findings indicate that information quality exerts a significant direct influence on student satisfaction (β = 0.547; p < 0.001) and an additional indirect effect mediated by perceived usefulness (β = 0.268; p < 0.001). Conversely, system quality and ease of use demonstrate no statistically significant effects. The coefficient of determination values (R² = 0.706 for satisfaction; R² = 0.615 for perceived usefulness) reflect a strong predictive capability of the model. These results affirm that information quality is the most salient predictor of user satisfaction, underscoring the imperative to prioritize content enhancement as a strategic direction in the advancement of academic information systems within the higher education landscape.

Abstract

This paper discusses the historical and political relations of the Patani Kingdom in Thailand and Patani in Takalar Regency, Indonesia. These two Patani had strong ties related to historical and political issues. This research uses qualitative methods with observational data collection techniques, interviews and documentation. Secondary data are obtained through textbooks, scientific journals, and online sources. The data were analyzed through the analysis of Miles and Haberman with the steps of data display, data verification and conclusions. This study found that the relationship between these two regions has occurred since 1634, where there was a massive exodus from Patani, Thailand to the Patani region in the Sanrobone Kingdom, Takalar, Indonesia due to the conflict that occurred between the Kingdom of Siam and the Kingdom of Patani in Thailand. Meanwhile, an important position in the politics of the Malays in Patani, Indonesia was as a royal clerk and harbormaster. On the other hand, the existence of the Bugis-Makassarese also had a political role in Patani, Thailand.

Abstract

Hospitals as one of the health service institutions that provide inpatient, outpatient and emergency services, in their implementation can produce waste in solid, liquid or gas form which can pollute the environment. Hospital waste water is an accumulation of domestic waste and liquid biomedical waste with high levels of organic pollutants, so it can be treated biologically. Liquid biomedical waste contains many microorganisms where the presence of microorganisms, in this case bacteria, can be used as an indicator of waste management and unfavorable environmental conditions. One waste water treatment technology that is safe for the environment is using bacteria that have the potential to act as decomposers in the biodegradation process. To obtain bacteria that have the potential to act as natural decomposers, you can isolate the waste itself. The bacteria found in liquid biomedical waste make it possible to find a group of non-pathogenic hydrolytic bacteria where this group of bacteria can produce various enzymes that are capable of degrading liquid biomedical waste. Gram staining is a method to differentiate between types or spesies of bacteria namely gram-positive bacteria and gram-negative bacteria. The aim of this study was to identify bacteria using Ziehl Neelsen gram staining. The results of the research showed that there were two bacterial isolates that were gram negative, namely isolate codes UH1.1 and UH1.2 (bacillus) form characterized by the appearance of brick red cells and five isolates that were gram positive, namely isolate codes UH1.3, UH2.1 (bacillus) UH2.2, UH2.3 and UH3.1 (coccus form) are characterized by the appearance of purple cells, the difference in color is due to differences in the composition of the cell walls of each bacteria.
