Abstract

Pemanfaatan Hasil Hutan Bukan Kayu (HHBK) berperan penting dalam peningkatan kesejahteraan masyarakat, namun limbah biomassa dari pengolahan komoditas hutan, termasuk kulit buah aren (Arenga pinnata Merr.), masih jarang dimanfaatkan dan berpotensi mencemari lingkungan. Penelitian ini bertujuan melakukan skrining fitokimia terhadap kulit buah aren dari hutan rakyat di sekitar Jalan Wan Abdul Rahman Lampung, untuk mengungkap kandungan senyawa bioaktif di dalamnya sebagai dasar ilmiah pemanfaatannya sebagai bahan baku produk alami bernilai tambah. Kulit buah aren diekstraksi dengan metode maserasi menggunakan etanol 96%, kemudian ekstrak diuji secara kualitatif melalui skrining fitokimia menggunakan pereaksi standar untuk mengidentifikasi golongan metabolit sekunder dan primer. Hasil menunjukkan bahwa ekstrak kulit buah aren mengandung flavonoid, senyawa fenolik (termasuk fenol hidrokuinon dan tanin), saponin, steroid/triterpenoid, dan alkaloid, serta metabolit primer berupa asam amino dan gula pereduksi. Keberadaan golongan senyawa tersebut mengindikasikan potensi aktivitas biologis, terutama sebagai antimikroba dan antioksidan alami, yang relevan untuk pengembangan produk berbasis bahan alam di bidang pangan, farmasi, dan kimia. Studi ini memberikan informasi awal mengenai potensi kimia kulit buah aren sebagai sumber senyawa bioaktif. Dengan demikian, kulit buah aren yang selama ini hanya menjadi limbah berpeluang dioptimalkan pemanfaatannya sebagai sumber HHBK bernilai tambah sekaligus membantu menurunkan beban limbah biomassa di lingkungan sekitar lokasi pengolahan.

Abstract

This study investigates sentiment analysis on user reviews from Bukalapak, a major Indonesian e-commerce platform, using the Multinomial Naïve Bayes (MNB) classifier. The study focuses on tackling the challenge of data imbalance and the linguistic complexities of Indonesian, such as slang, affixes, and negation, which are common in user reviews. Data was collected through web scraping from Bukalapak's app on the Google Play Store, resulting in a dataset of 19,999 reviews. A structured preprocessing pipeline was employed, including text normalization, tokenization, stopword removal, stemming, and term frequency-inverse document frequency (TF-IDF) weighting to prepare the data. The sentiment analysis results show that the model performs well in categorizing neutral reviews (accuracy 81%), but struggles with positive and negative sentiments due to data imbalance, leading to lower accuracy for these categories. The study highlights the effectiveness of Multinomial Naïve Bayes in large-scale sentiment analysis tasks in the e-commerce domain, particularly for platforms with large volumes of user-generated content. The study also introduces SMOTE (Synthetic Minority Over-sampling Technique) for handling data imbalance and k-fold cross-validation for model evaluation, significantly improving the model’s reliability. The research concludes that sentiment analysis can greatly benefit e-commerce platforms by improving customer service, informing product management decisions, and providing valuable insights for business strategies.

Abstract

Antimicrobial resistance (AMR) has increased interest in sustainable bioresources as alternative antimicrobial candidates. This study mapped the bioactive compound profile of wild sugar palm (Arenga pinnata Merr.) fruit peel waste collected from the Wan Abdul Rahman Forest area, Lampung, Indonesia. It established a preliminary chemical basis for its antimicrobial potential. Qualitative phytochemical screening of a 96% ethanol extract confirmed the presence of flavonoids, phenolics, tannins, saponins, steroids/triterpenoids, alkaloids, amino acids, and reducing sugars, indicating a diverse spectrum of secondary metabolites associated with antimicrobial and antioxidant activities. GC–MS analysis of methanol–chloroform (8:2) and chloroform extracts identified 31 compounds, dominated by 1-eicosanol, 9,12-octadecadienoic acid methyl ester, 9-octadecenoic acid methyl ester, octadecanoic acid methyl ester, hexadecanoic acid methyl ester, and 1,2-benzenedicarboxylic acid diethyl ester. These findings provide a chemical baseline supporting sugar palm fruit peel waste as a promising local source of value-added natural bioactive compounds.

Abstract

The development of information technology encourages government agencies to carry out digital transformation in archive management to increase administrative efficiency and effectiveness. The Communication and Information Service of East Lampung Regency still faces obstacles in the management of cooperation documents that are carried out manually, such as difficulties in searching archives and the risk of data loss. This research aims to design and build a web-based Cooperation Document E-Archive Information System as a solution to these problems. The system development method used is the Prototype method, which allows direct interaction between developers and users in the system development process. The system is built using PHP 8.1 with the Model-View-Controller (MVC) architecture and MySQL 8.0 as the database. Black-box testing conducted on 25 test cases achieved a 100% success rate, confirming that all functional requirements were met without errors. User Acceptance Testing (UAT) yielded an acceptance score of 92%, indicating a high level of user satisfaction and system usability. These results demonstrate that the developed system effectively simplifies the document management process—from storage and retrieval to structured archival grouping, thereby improving work efficiency and supporting the implementation of the Electronic-Based Government System (SPBE) in the relevant agencies.

Abstract

This study aims to analyse the vehicle characteristics and traffic density pattern at Mayjen Yusuf Singedekane road section on Palembang which is under the observation of Unit Pelaksana Penimbangan Kendaraan Bermotor (UPPKB) Kertapati by using clustering and time series analysis to process the data recorded by Weigh-in-Motion (WIM) device. The data used in this study includes the time of record, total vehicle weight, number of axles, and weight per axle. The first analysis is performing clustering of the vehicles by weight and axle charactersitics using k-Means clustering method. Second step of the analysis is by finding the traffic density pattern using time series analysis STL Decomposition method to find a short seasonal cycle. These two analysis are done using Orange data mining tool. The result of this study separates the data into 3 clusters: C1 Light represents vehicles with low weight regardless of axles, C2 Heavy represents vehicles with heavy load and focuses on axle configurations between 2 to 4 axles, C3 Large-Heavy represents vehicles with heavy load and focuses on axle configurations between 5 to 6 axles. This study determines that the weekly density pattern peaks at Friday and reaches the lowest point at Saturday. Hopefully these findings are able to contribute to the planning of traffic management and road infrastructure maintenance efforts among other potential uses.

Abstract

Development of increasingly modern technological devices can provide advantages for entrepreneurs to market services and products with the aim of expanding market share with a wide reach. The scope of product sales in an area becomes ineffective in being able to compete to attract consumer interest. The role of information technology can be carried out using internet media so that consumers can access it online or can be called e-commerce. The object of this research was carried out at a hijab shop in the Natar area, South Lampung. The problems that exist include the sales process which is carried out directly, such as consumers coming to the shop to buy products, which has an impact on operational costs, energy and time, especially consumers who are in areas where they cannot see information on the availability of the product they want to buy. The system development method used is Extreme Programming. The results obtained are that the use of the website is running well, as evidenced by the results of system testing using blackbox testing of 91.66%, which means that this e-commerce information system is running successfully and can be used by consumers, especially in the South Lampung area and its surroundings.
