Abstract

Perusahaan UD. X tidak hanya mengirimkan saos saja namun melakukan pengambilan botol saos yang kosong. Perusahaan memiliki satu jenis kendaraan pickup L300 dengan muatan 50 krat dan perusahaan memiliki kebijakan bahwa produk dapat dilakukan pengiriman serta pengambilan botol dengan dilayani oleh lebih dari 1 kendaraan. Agar semua permintaan dapat dipenuhi maka UD. X ingin mengetahui rute yang optimal untuk melakukan pengiriman dan pengambilan botol dengan meminimasi biaya pengiriman serta meminimalkan jumlah kendaraan yang dibutuhkan untuk memenuhi semua permintaan. Dalam penelitian ini menggunakan metode vehicle routing problem: simultaneous delivery and pickup with split load. Dari hasil perhitungan bahwa untuk memenuhi 20 pelanggan dibutuhkan 3 kendaraan dimana setiap pelanggan dapat dilayani oleh lebih dari 1 kendaraan. Dari hasil perhitungan diperoleh hasil untuk subrute 1 yaitu 0-4-16-17-8-1-9-20-0 dengan total jarak 10,8 Km, untuk subrute ke 2 yaitu 0-15-19-6-18-3-20-2-5-0 dengan total jarak 13,79 Km, untuk subrute 3 yaitu 0-2-5-12-10-11-13-14-7-0 dengan total jarak 29.95 Km. Jika ditotal keseluruhan jarak dari 3 kendaraan yaitu 54.54 Km untuk memenuhi seluruh permintaan dengan total biaya pengiriman yaitu sebesar Rp 53.449.Kata Kunci: vehicle routing problem, simultaneous delivery and pick up, split load.

Abstract

In the neighborhood, there is a slew of flavored drink shops. Bubble drinks, sometimes known as "boba drinks," are currently popular across various demographics, particularly among teenagers and young people. The sweet taste of the drink and the range of options drive demand for this boba drink, which is growing increasingly popular. In addition to its presentation, this beverage producer offers customization options for beverage taste, sugar level, drink glass size, and even ice cube quantity to satisfy consumer preferences. Several criteria, such as pricing, purchasing power, and location, must be considered while deciding on store opening These elements can still be subdivided. Therefore the AHP (Analytical Hierarchy Process) method is appropriate for determining store openings. The findings of this study demonstrate that, among numerous alternative locations, location G has the highest value, with a weight of 0.2236.

Abstract

Kue kering merupakan salah satu makanan ringan yang diminati oleh berbagai macam usia, mulai anak-anak hingga dewasa. Demand kue kering akan meningkat pada saat hari raya. Kue kering dapat dijadikan hadiah kepada teman, keluarga ataupun partner kerja. Menjamurnya pengusaha kue kering membuat para produsen harus meningkatkan kualitas pelayanan mereka. Salah satu cara peningkatan pelayanan dapat dilakuakan dari sisi pengiriman yang tepat waktu. Ketepatan waktu dalam pengiriman kue kering menjadi faktor yang penting untuk sebuah pengusaha, hal ini dikarenakan terkait dengan biaya, maka dengan menentukan rute yang tepat diharapkan dapat meminimalkan biaya. Dalam pengiriman kue kering dari satu pelanggan ke pelanggan lainnya harus memperhatikan time windows dari masing-masing pelanggan, selain itu juga memperhatikan kapasitas kendaraan. Dalam permasalahan ini, setelah mengantar kue kering ke pelanggan, kendaraan akan mengambil bahan baku kue di beberapa toko. Permasalahan ini dapat diselesaikan dengan Vehicle Routing Problem with Backhauls Time Windows (VRPBTW). Penelitian ini menjelaskan proses penentuan rute pengiriman kue dan pengambilan bahan baku dengan menggunakan Nearest Neighbour dan dilakukan perbaikan dengan 2-Opt. Hasil dari penelitian ini diperlukan tiga kendaraan untuk dapat melayani semua pelanggan menggunakan VRPBTW dengan total waktu tempuh 763.2 menit dan jarak tempuh 57.9 km.

Abstract

The food and beverage industry are gaining significant attention among the public, as evidenced by the increasing number of food and drink outlets emerging. In some cities, there are even dozens of outlets due to the high level of enthusiasm among people. One particularly popular type of drink outlet currently is boba or bubble tea. Previous research has been conducted to identify potential locations for new outlets. Following the recommendations for new outlets, the research continued by determining the delivery routes for raw materials. The objective of this research is to establish new distribution routes for existing beverage outlets across several locations to minimize travel distance and transportation costs. This study utilizes the Vehicle Routing Problem with Time Windows (VRPTW), which is the most used VRP model in the industrial sector. The results of this research yielded two routes, with distances of 96.4 km and 35.7 km respectively, and travel times of 289.2 minutes and 163.5 minutes.

Abstract

Mathematics is a subject that is rarely popular with school students. Difficult material, complicated calculations, dan material that is less interactive when delivered in class are the reasons why this subject is less popular. Technological assistance, such as software, is an important thing to do in order to increase interactive learning. One of the software that is suitable for use as learning support, especially for mathematics dan science subjects, is MathCAD. This MathCAD software can help educators create math problems dan compile exercise books more quickly. The aim of this community service activity is to assist mathematics dan science teachers in teaching dan learning activities, especially in exact subjects. The method used is implementing MathCAD software training for the mathematics dan science teacher communities. With the results obtained from community service activities in the form of MathCAD software training, educators can apply the use of software during the teaching dan learning process, especially mathematics, to make it more interactive.

Abstract

Guidance and Counseling (BK) has an important role in supporting the academic, social and emotional development of students in high school. However, recording and managing guidance and counseling services which are still done manually often creates obstacles, such as limitations in data retrieval, lack of privacy, and difficulties in maintaining student development on an ongoing basis. To overcome this problem, the use of digital systems in BK services is an effective solution. The BK digital system allows for more structured student data recording, faster access, as well as features such as counseling scheduling and student progress reports. This community service aims to build an application-based counseling guidance system that makes it easier to record counseling and violations committed by students. So far, counseling has been carried out by recording it in a counseling book, or if a customer commits it, it will be recorded on a violation card, which over time will fill the storage locker and it is also difficult to make mass data changes when a class changes guidance and counseling teachers. The counseling guidance application that has been created can meet the needs of guidance and counseling teachers for scheduling counseling and can see a brief description of the number of counseling activities in a particular month and can also print the results of the counseling

Abstract

Transformasi digital dalam administrasi pendidikan menjadi kebutuhan mendesak untuk meningkatkan efektivitas, efisiensi, dan akurasi data, khususnya dalam pencatatan kehadiran siswa. SMP Al-Falah Assalam Sidoarjo menghadapi kendala akibat kerusakan sistem presensi fingerprint yang sebelumnya digunakan, sehingga kembali pada metode manual berbasis tanda tangan yang rawan manipulasi dan kurang efisien. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk merancang dan mengimplementasikan sistem presensi digital berbasis fingerprint dengan dukungan mikrokontroler Arduino, serta integrasi WhatsApp API untuk mengirimkan notifikasi kehadiran siswa secara real-time kepada orang tua. Metode pelaksanaan meliputi identifikasi kebutuhan sekolah, perancangan perangkat keras dan lunak, pelatihan penggunaan sistem, serta evaluasi efektivitas sistem melalui pendekatan kualitatif. Hasil implementasi menunjukkan adanya peningkatan signifikan dalam efisiensi kerja administrasi, keterlibatan orang tua dalam pemantauan kehadiran siswa, dan peningkatan kedisiplinan siswa. Sistem ini dinilai mudah dioperasikan, fleksibel, dan adaptif terhadap kebutuhan sekolah. Keberhasilan kegiatan ini membuka peluang untuk replikasi di institusi pendidikan lain yang menghadapi tantangan serupa, khususnya dalam upaya modernisasi administrasi sekolah melalui teknologi terintegrasi.
