Abstract

Melon (Cucumis melo L.) is one of potential horticultural crop in Indonesia. Unfortunately, melon production is currently unable to meet national demand. The objective of this study was to investigate the effect of biofertilizer, varieties and interaction between the dose of biofertilizer and varieties on the growth and yield of melons. The study was conducted in January-April 2021 at Paloh Lada Village, Dewantara District and the Laboratory of Agriculture Faculty, Universitas Malikussaleh. These experiments were arranged in a Factorial Randomized Block Design (RBD) with two factors. The first factor was biofertilizer (P) consisting of 4 levels: P0 (0 ml/L), P1 (5 ml/L), P2 (10 ml/L) and P3 (15 ml/L) and the second factor was melon varieties (V): V1 (F1 Pertiwi Anvi) and V2 (F1 Action 88). There was 8 treatment combinations with 3 replications, resulted in 24 experimental units. The interaction between biofertilizers and varieties gave significant effect on the growth and yield of melon, while the interactions between bio fertilizer did not differ on all variables observed. The application of biological fertilizer 10 ml/L on V1 variety (F1 Pertiwi Anvi) is recommendable. There was an interaction between of biological fertilizers and melon varieties on the total dissolved solids (Brix %).

Abstract

Salon service providers are companies that provide hair, facial, body and other beauty treatments to the public. Many people are currently doing business in this field, and many business people are opening salons in various locations, starting from city areas and densely populated village areas. In Aceh Province there are 200 salons. The benefit of this application is that it can identify the recommended salons for each city/district and the shortest route to the salon that the service user will go to. In the initial stage, spatial data on salons in Aceh Province was collected and entered into a geographic database. The weights of relevant criteria such as service quality, price, location, sanitation cleanliness, and customer service are determined using the SAW method. After that, SAW is used to calculate the total score for each salon based on these criteria. Salons are then ranked by highest total score to provide recommendations that match user preferences. Next, Dijkstra's algorithm is used to determine the shortest route between the user's location and the selected salon. This helps users to plan trips efficiently and save time. The implementation of GIS and algorithms is integrated in the form of a website to facilitate access and use by the general public. Users can easily find the best salon based on their selection criteria, as well as get optimal directions. It is hoped that this research can contribute to advancing the salon industry in Aceh Province by providing practical and effective solutions for the public in choosing a salon that suits the community's needs.

Abstract

Kitab matan taqrib merupakan salah satu kitab fiqh mazhab Imam Syafii yang mana dalam kitab ini mencakup semua bab yang ada dalam kitab fiqh lainnya namun pada kitab ini pembahasannya dijelaskan secara ringkas, karena kitab ini merupakan kitab fiqh yang dipelajari pada tingkatan yang pertama. Fiqh merupakan salah satu bidang ilmu dalam syariat Islam yang secara khusus membahas persoalan hukum yang mengatur berbagai aspek kehidupan manusia, baik kehidupan pribadi, bermasyarakat maupun kehidupan manusia dengan Tuhannya. Sebagai ummat islam kita dituntut untuk  megetahui hukum-hukum syariat, agar  ibadah kita diterima oleh Allah Taala, kita tidak dapat memahami ilmu fiqh  kecuali setelah mengetahui kaidah-kaidah bahasa Arab, khusus nya ilmu Nahwu dan Sharaf. Namun yang akan di bahas disini ialah mengenai ilmu Nahwu. Oleh karena itu, sistem pendeteksi pola fiil Mudharik diperlukan untuk membantu pengguna menemukan pola-pola fiil mudharik dalam  Kitab Matan Taqrib. Dalam penelitian ini, Metode Cosine Similarity digunakan untuk menghitung  jarak kemiripan pola fiil mudharik pada citra Kitab Matan Taqrib. Dari hasil pengujian yang telah dilakukan, persentase keberhasilan data uji dimana untuk  Bab Puasa   100%  dan persentase untuk Bab Thaharah  adalah  78,79%. Persentase detection rate tersebut menunjukkan bahwa metode Cosine dapat digunakan sebagai salah satu pendekatan untuk pendeteksian pola Fiil Mudharik pada citra Kitab Mata Taqrib. Sistem ini memiliki beberapa kelemahan yaitu memiliki false positive rate yang tinggi, sebagaimana dapat dilihat pada unjuk kerja dari sistem pendeteksi pola fiil mudharik ini, proses keakurasiannya dapat dilakukan dengan memberikan pelatihan lebih lanjut dengan tambahan data training yang lebih banyak dan lebih bervariasi. Walaupun begitu, sistem pengenalan pola fiil mudharik  ini tidak menafikan pentingnya guru dalam belajar  ilmu nahwu yang benar.Kata kunci : Pengolahan Citra, Kitab Matan Taqrib, Pola Fiil  Mudharik, Cosine Similarity

Abstract

The selection of cafés that match customer preferences is a challenge, especially in the city of Lhokseumawe, which has 30 cafés with different characteristics. This research implements the Simple Additive Weighting (SAW) algorithm to provide recommendations for the best café based on six criteria, namely price (weight 0.25), menu (0.2), order duration (0.15), service (0.2), facilities (0.15), and discounts promotions (0.05). The recommendation system was developed using a combination of Laravel PHP and Python, where Laravel is used to build an interactive web interface. Python also plays a role in data processing and complex mathematical calculations. The results showed that the system was able to provide optimal recommendations, with Petrodollar Coffeeatery Roastery as the top choice based on the calculation of the highest preference values (3.28 for price, 2.48 for menu, 3.16 for order duration, 2.88 for service, 2.96 for facilities, and 2.8 for discounts promotions). TR Coffee and Platinum Coffee occupy the following positions. In addition, this study found that the weight of the criteria and the number of datasets (150 reviewers) significantly influence the quality of recommendations. The more representative the weights used and the larger the dataset analyzed, the more accurate the system will produce recommendations based on user preferences. Thus, weight optimization and dataset expansion are essential factors in improving the effectiveness of SAW-based recommendation systems.

Abstract

Drug supplies are an important aspect because of their large value and large quantity and are an important factor in supporting health services in community health centers. Ineffective drug management, especially in terms of needs planning, can lead to excess or shortage of stock. Both conditions have negative impacts, such as budget waste, drug expiration, or even disruption of patient services due to unavailability of drugs. At the Pante Bidari Health Center UPTD, the drug needs planning process is still carried out manually or based on rough estimates without using sophisticated technology. This study aims to design and build a web-based drug inventory prediction system using the Least Square method. The Least Square method was chosen because it is able to carry out the forecasting process quickly and with good results. In this study, the type of data obtained is drug usage data, data is grouped based on each supplier, from the health center information system during a certain period. After going through the pre-processing and calculation stages, the predicted values are calculated and displayed through a web-based system designed to be easy to use by health center officers. The web system developed in this study uses PHP as the programming language and MySQL as the database, implementing the Least Square method effectively. The results of this study are a drug usage prediction application for the future, applying the Least Square method, which displays drug usage data over a certain period. The system will present the data in the form of a table. Based on testing the drug usage data for Acyclovir Cream 5 mg from January 2023 to August 2024, the prediction result for the following month, September 2024, is estimated to be 38.415, which is rounded to 38 units of the drug.
