Abstract

ABSTRACT---Lichens are symbiotic plant composed of two different types of organisms i.e. fungi and algae. Lichens sensitive to air pollutan of sulfur dioxide (SO2). Sikidang creater are still active to emist off SO2 and will be affected the availability of lichens as well as the their individual density along SO2 gradient. Sampling of lichens taken with sistematic method. Point sampling four were taken along transect line and sample plot 5 m x 5 m in size was applied..The occurance of species and density was record in every sampling plot. The environment factor measured were air SO2, pH, moisturized and air temperature. There were three species of lichens in Sikidang Creater, those are Cladonia beaumontii, Dactylina artica abd Parmelia cumberlandia. The highets density of species lichens is Cladonia beaumontii.   Keywords : density, Lichens. Sikidang Creater

Abstract

The dissemination of information at the village level is crucial for ensuring transparency to the residents. To facilitate the quick and easy communication of such information, a web-based village information system was developed. This system can be accessed by all community members, both within and outside the village, as long as they have an internet connection. Currently, Hegarmukti Village does not have an effective web-based information system, leading to delays in information delivery and a lack of accuracy. Moreover, the potential of the village remains under-promoted. This study aims to design and implement a web-based village information system for Hegarmukti Village using the Waterfall method. The system is developed using HTML for programming and MySQL for the database, with the goal of enhancing transparency and the efficiency of information dissemination. The system provides features such as village profiles, news updates, and population data searches, improving the accessibility and reliability of village information.

Abstract

The web-based church congregation information system has become a modern solution that makes it easier for churches to manage congregation data and church activities more efficiently and organized. This research reviews the implementation of the church congregation information system in HKBP Cikarang City which previously used manual methods with notebooks. The main problem faced is the limitations of manually managing congregational data which often results in inaccurate data and operational inefficiencies. By implementing a web-based information system using the Waterfall method, this research aims to increase the efficiency and accuracy of congregation data management. The research results show that the information system developed is able to increase the accuracy of congregational data and reduce data management time by up to 60%, while increasing data accessibility for church administrators. These findings provide support that the implementation of a web-based information system can provide an effective solution to overcome the challenges of managing congregational data faced by HKBP Cikarang City. This system can be adapted and applied to other churches that have similar needs, thereby increasing the efficiency and accuracy of congregation data management in various churches.

Abstract

The quality of education in Indonesia is still a concern, seen from a number of problems that become obstacles to improving the quality of education as well as affecting the quality of Indonesian youth. This study aims to group provinces in Indonesia based on the aspect of youth education using the K-Means and K-Medoids methods. To determine the optimum k, the average silhouette method is used and the SW and SB ratio is used to evaluate the cluster results. The results obtained are 2 clusters optimum. For the K-Means method, cluster 1 consists of 19 provinces and cluster 2 consists of 14 provinces. Whereas in the K-Medoids method, cluster 1 consists of 22 provinces and cluster 2 consists of 11 provinces. The K-Means method is better than the K-Medoids method because it has a ratio value of 0.527941 which is smaller than the K-Medoid ratio value of 0.5612719.Keyword: K-Means; K-Medoid; Education; Average Silhouette; Standard Deviation.

Abstract

Drl.Rumahan is a retail store that sells a variety of motorcycle lamp modifications. Drl.Rumahan is still struggling with determining stock levels and understanding customer purchases. Additionally, they are not utilizing transaction data as a valuable information source. Without leveraging this data, Drl.Rumahan will fall behind its business competitors and lose customers because the products they seek are unavailable. This situation will inevitably become a significant problem if it continues. This study aims to utilize sales transaction data as valuable information and identify customer purchasing patterns from the sales transaction data. The algorithm used is the Apriori algorithm to identify purchasing patterns from the transaction data set. The results of this study identified the three highest rules: if someone buys a pass beam switch, they will buy a shroud with a support value of 5.8% and a confidence value of 47.6%; if someone buys a shroud, they will buy a pass beam switch with a support value of 5.8% and a confidence value of 45.5%; and if someone buys a shroud, they will buy a relay with a support value of 5.2% and a confidence value of 40.9%. These results can inform business strategy decisions by increasing the inventory of products that form rules and serve as a guide for promotional product packages for products that have rules above the minimum support and minimum confidence.

Abstract

Minimarket adalah sebuah usaha yang menawarkan berbagai macam barang mulai dari makanan, sembako, peralatan dapur serta ditunjang dengan fasilitas dan tempat yang nyaman bagi pelanggan. Seiring berjalannya waktu ritel tradisional banyak yang gulung tikar. Berubahnya pola belanja masyarakat hal tersebut juga terjadi di Yogyakarta. Oleh karena itu dibutuhkan analisis terhadap faktor yang berpengaruh. Dalam hal ini analisis yang digunakan adalah Principal Component Analysis (PCA). PCA adalah suatu metode yang melibatkan prosedur matematika yang mengubah dan mentransformasikan sejumlah besar variabel yang berkorelasi menjadi sejumlah kecil variabel yang tidak berkorelasi, tanpa menghilangkan informasi penting di dalamnya. (Jatra, Isnanto, & Imam, 2007). Hasil diperoleh hasil sebagai berikut: Faktor menjamurnya Toko Ritel Modern di Yogyakarta yaitu terdapat 5 komponen PCA. Faktor yang dapat mempengaruhi keberlangsungan Toko Ritel Tradisional di Yogyakarta yaitu terdapat 3 komponen PCA. Faktor pembanding Toko Ritel Tradisional agar tetap bertahan yaitu terdapat 3 komponen PCA.
