Abstract

Tourism is an activity for someone who wants to take a vacation or travel to a place within a certain period of time and return to the place of origin with the aim of taking a short break from daily activities. Tourism has become one of the most important economic sectors in many tourist destinations around the world, including Kuta. Kuta is a tourist area located on the island of Bali, Indonesia. Kuta has become one of the most popular tourism destinations in Bali, as well as one of the most famous tourist destinations in all of Indonesia. Kuta has many attractions such as beautiful beaches, quite active nightlife, and various culinary. However, the rapid growth of tourism also brings a number of challenges that must be faced. Therefore, the creation of a Geographic Information System (GIS) as a web-based tourism mapping tool becomes relevant. With so many culinary spread in Kuta, tourists who cannot eat pigs are very difficult to find food that does not use pork content. Because, in Kuta there are so many foods that contain pork. Therefore, with the creation of this application, tourists do not need to worry because this application can provide input on culinary places that do not contain pork. To develop this GIS research using the SDLC method which includes planning, analysis, design, and implementation.

Abstract

The celebration of Eid al-Adha is an annual holiday observed by Muslims worldwide. Every 10th of Dhu al-Hijjah, Muslims perform the Eid al-Adha prayer followed by the sacrificial ritual for those who are financially able. In Indonesia, the sacrificial ritual involves slaughtering animals such as goats, sheep, or cows, with the meat subsequently distributed to those in need in accordance with Islamic law. Conventional methods of distributing sacrificial meat can lead to issues such as long queues and an unorganized environment, as well as repeated distribution to the same individuals, causing unfair distribution of the meat. Every year, Nurul Iman Mosque in Pesanggrahan, South Jakarta conducts the slaughter and distribution of sacrificial meat to over 250 recipients. In the Community Service Activity (PKM), the author plans to develop a barcode-based queuing system to reduce the potential for repeated meat collection and to speed up the distribution process at Musala Nurul Iman in Pesanggrahan, South Jakarta. The methodology includes system design, creation of barcode coupons, socialization to the committee, and implementation evaluation. Evaluation results indicate that this system successfully reduced waiting times and made meat distribution more orderly. It is hoped that the application of this barcode-based queuing system can be adopted by other musollas or mosques conducting similar activities, thereby making the process of sacrificial meat distribution more effective and efficient. ABSTRAK Perayaan Idul Adha merupakan hari raya yang diadakan setiap tahun oleh umat muslim di seluruh dunia. Setiap tanggal 10 Dzulhijjah uman muslim menjalankan shalat Idul Adha dilanjutkan ibadah kurban bagi yang mampu secara finansial. Di Indonesia, ibadah kurban adalah dilakukan dengan cara menyembelih hewan kurban seperti kambing, domba, atau sapi yang kemudian dagingnya dibagikan kepada masyarakat yang membutuhkan dan dilaksanakan sesuai dengan syariah. Pendistribusian daging kurban yang masih konvensional mengakibatkan beberapa masalah seperti antrean panjang dan kurang kondusif, penerimaan berulang daging kurban pada orang yang sama menyebabkan ketidakadilan pendistribusian daging kurban. Musala Nurul Iman Pesangrahan Jakarta Selatan setiap tahun melakukan peyembelihan kurban dan pendistribusian daging kurban sebanyak 250 lebih penerima setiap tahunnya. Dalam Kegiatan Pengabdian Kepada Masyarakat (PKM), Penulis akan mengembangkan sebuah sistem antrean berbasis barcode untuk mengurangi potensi pengambilan daging kurban secara berulang dan mempercepat waktu distribusi di Musala Nurul Iman Pesanggrahan Jakarta Selatan. Metodologi yang digunakan meliputi perancangan sistem, pembuatan kupon barcode, sosialisasi kepada panitia, serta evaluasi pelaksanaan. Hasil evaluasi menunjukkan bahwa sistem ini berhasil mengurangi waktu antrean dan distribusi daging kurban lebih tertib. Diharapkan aplikasi sistem antrean berbasis barcode ini dapat diadopsi oleh Musala atau masjid yang melaksanakan kegiatan serupa, sehingga proses distribusi daging kurban dapat berjalan lebih efektif dan efisien.

Abstract

Indonesian SMEs contribute 15.8% to the global production supply chain at the ASEAN level. Operating in the culinary sector of Palembang specialties, UMKM Pempek Davin has the potential to expand further. If relying on conventional marketing, the marketing reach is limited. This MSME is trying to pioneer the development of its marketing potential through digital media to face the increasingly tight business competition in the digital era (start-up). Therefore, this Community Service (PKM) aims to enhance marketing efforts through website creation. The website development method includes business needs analysis, system design, website development, as well as training and mentoring in website management and digital marketing strategies. This activity is carried out in several stages, starting from data collection on the current marketing conditions, website design and implementation, and concluding with an assessment of how effectively the website improves visibility and product sales. The result of this activity is the creation of a marketing website that allows UMKM Pempek Davin to promote and sell its products online. Additionally, the UMKM owners were trained to manage the content on the website and understand effective digital marketing strategies, enabling them to expand their marketing reach through search engines and enhance the credibility of UMKM Pempek Davin by having an official digital media presence. Next, the website maintenance process will be carried out in the form of knowledge transfer from the PKM implementation team to the partner team, including the handover of the website's source code, website administrator accounts, and website usage instructions to the staff designated by the partner team. ABSTRAK UMKM Indonesia memiliki kontribusi sebesar 15.8% terhadap rantai pasok produksi global di tingkat ASEAN.

Abstract

Food prices are important global issue and their relationship with fuel prices has become a main concern in society. An increase in the subsidized fuel price on 3 September 2022 has allegedly caused a rise in food (grocery) prices. This paper conducts an empirical study to analyze the relationships between food prices in Indonesia: rice, chicken, beef, egg, red chili, cayenne, shallot, garlic, cooking oil, and sugar. The study uses time series data of food prices from 1 January 2018 to 31 December 2023, which consists of food prices from 87 traditional markets in Indonesia. The commodity prices are obtained from online public data provided by Bank Indonesia. It divides the analysis (pre- and post-3 September 2022) to see how the relationship between food prices changes due to the increase in the subsidized fuel price. It performs the Peter Clark (PC) algorithm to generate causal graphs from real datasets where the true graphs are unknown, complements the analysis by performing Vector Autoregression (VAR) to investigate the dynamic relationship between food prices, especially how the subsidized fuel price increase changes its dynamic relationship. The causal graphs from pre- and post-increasing fuel prices show the changes in the role of variable relationships, e.g., sugar and beef. The VAR results also show an interesting change in the IRF pattern. The results from both the PC algorithm and VAR show that there is a structural change in the relationship between food prices and that there is a different effect of price shock due to the subsidized fuel price increase. It might have been an indication of a change in the consumption pattern in society as a response to a food price increase. This must be a huge task to do in maintaining food prices when there is an adjustment in the subsidized fuel prices.

Abstract

A multidimensional approach to mapping poverty in Indonesia necessitates the use of the Human Development Index (HDI), Poverty Line, and Expenditure per Capita. This study aims to evaluate the performance of two clustering algorithms with distinct paradigms the centroid-based Fuzzy C-Means (FCM) and the density-based OPTICS in profiling poverty across 501 regencies and cities. Experimental results indicate that OPTICS achieved high internal validity, with a Silhouette Score of 0.7301 and a Davies-Bouldin Index (DBI) of 0.329. Significantly, OPTICS identified 94% of the data as noise. This finding reveals a fundamental characteristic: the distribution of socio-economic data in Indonesia is highly heterogeneous and sparse, lacking inherently dense cluster structures. Conversely, FCM, employing a soft clustering approach, successfully accommodates the ambiguity of data boundaries and provides comprehensive segmentation across all regions. Despite yielding lower validity metrics (Silhouette Score 0.3894), FCM was selected as the final model because it satisfies the practical requirements of the application, which demands complete coverage mapping. This study concludes that a soft clustering approach is more applicable than density-based clustering for analyzing highly heterogeneous data such as that found in Indonesia
