Abstract

An advanced public transportation system becomes an indicator for a country. Accordingly, it is essential that the decision-makers (DMs) conduct an initial study based on passengers’ view in order to improve the public transportation services. Since involving multi factors, the problem is often solved using the multi-criteria decision-making (MCDM) approaches. This study aims to examine significant factors on passengers decision making to use public transportation using Fuzzy AHP and DEMATEL. The Fuzzy AHP method is proposed to determine criteria weights so that significant critera are obtained, then the causal relations including the criteria are visualized using DEMATEL. This study demonstrates the integration of the two MCDM methods in a BRT system in the region of Yogyakarta, Indonesia, and invites passengers and the DMs. The result indicated that 21 criteria are identified, while the 11 significant criteria are selected based on the Fuzzy AHP weight – α-cut screening. Besides, the DEMATEL has succeeded in describing the influence relationship for the criteria, where firstly, the significant criteria are classified into cause and effect group and secondly, the two criteria, namely coverage to strategic points and on time arrival, should be put on the top priority list. This study enables the DMs to solve public transportation problems more effectively. However, the follow-up study should be carried out by including other factors such as economic and sustainability to strengthen the decision-making process.

Abstract

Transportation plays some important roles in supply chain management. It contributes significantly towards a business performance. Therefore, a company needs to plan its transportation system. A good transportation planning is able to lead in either efficiency or responsiveness. This paper addresses to build a mathematical model of determination of supplier contracts in a transportation problem. In this case, a company already selected a supplier partnership or, in other words, third-party logistics (3PLs) who provides trucks to be rented. The 3PLs also offers three options of contracts to the company, and the company should sign which contracts that can minimize rental costs and meet the company’s demands. This model is a linear-programming model. Using a numerical example, the problem is solved with LINGO.

Abstract

Manusia membutuhkan suatu pendidikan untuk mengasah keterampilan dalam memenuhi kebutuhan sehari-hari, baik dalam dunia usaha atau pun industri. Pendidikan tersebut dapat diperoleh melalui pendidikan formal maupun non-formal. Data statistik kementerian pendidikan dan kebudayaan Daerah Istimewa Yogyakarta (DIY) menunjukkan jumlah pendidikan non formal tahun 2018 sejumlah 433. Pendidikan non-formal melalui pendidikan ketrampilan telah menunjukkan kontribusi positif terhadap penurunan angka kemiskinan dalam pembangunan pedesaan. Smart Colleague hadir sebagai salah satu dari pendidikan non formal di Yogyakarta untuk memberikan pendukung pendidikan komputer sejak usia dini. Di tengah peluang yang menjanjikan ini belum banyak pelaku bisnis pendidikan non formal yang memanfaatkan teknologi informasi sebagai sarana promosi dan informasi. Berawal dari keterbatasan pengetahuan akan teknologi informasi inilah konsep pengabdian pada masyarakat ini disusun. Kegiatan pengabdian masyarakat ini membantu Lembaga Pendidikan Non Formal dengan sampel satu mitra, yaitu Smart Colleague yang bergerak di bidang pelatihan komputer yang fokus mengembangkan edu-games, baik untuk pra-sekolah, Siswa SD, dan juga dewasa. Kegiatan ini dilakukan dalam jangka waktu enam bulan. Tujuan dari kegiatan ini adalah memberikan pelatihan kepada relawan dan pengajar di Smart Colleague agar dapat memanfaatkan teknologi informasi untuk mempromosikan jasanya. Teknologi informasi yang digunakan adalah sistem informasi website.

Abstract

Gereja dapat diartikan dalam dua hal, yaitu sebagai tempat beribadah umat Kristen dan juga suatu badan yang mengelola kegiatan-kegiatan umat Kristen, baik yang bersifat liturgis atau non-liturgis. Demikian pula dengan Gereja Santo Petrus Warak yang selalu mengagendakan kegiatan-kegiatan tersebut. Sejauh ini, Gereja tidak banyak memberitakan kegiatan atau perkembangan yang ada di Gereja karena beberapa keterbatasan, seperti media dan sumber daya. Akibatnya, banyak umat tidak tahu perkembangan gereja. Media yang sering digunakan Gereja untuk mendistribusikan informasi kegiatan adalah pengumuman, teks misa, tabloid, buletin, dan majalah Gereja. Kelemahan media ini adalah informasi terpisah-pisah sehingga dokumentasi kegiatan Gereja tidak terpusat. Hal itu dikarenakan proses pemberitaan dilakukan oleh banyak orang dan data tidak terpusat di Gereja. Melihat permasalahan tersebut, dibuatlah website yang dapat digunakan untuk menyebarkan informasi kepada umat Gereja. Pengurus Gereja dapat menginformasikan profil Gereja, kegiatan-kegiatan apa saja yang akan dilakukan di Gereja, dan formulir-formulir yang diperlukan untuk administrasi Gereja. Selain itu, website ini memungkinkan umat untuk berpartisipasi mengirimkan berita tentang kegiatan liturgis atau non-liturgis di wilayah masing-masing. Pembuatan fitur website ini bertujuan untuk menjawab tantangan terbatasnya sumber daya manusia untuk mengunggah berita secara berkala.

Abstract

Abstrak— Tujuan dari penelitian ini adalah untuk mengevaluasi kinerja karyawan di sebuah pabrik fitting pipa yang terletak di wilayah Yogyakarta, Indonesia, dengan menggunakan teknik pengambilan keputusan multi kriteria (MCDM). Pabrikan saat ini telah melakukan evaluasi kinerja; namun, ada dua kelemahan dalam penilaian sistem saat ini. Pertama, metode saat ini tidak dapat menentukan prioritas kriteria. Kedua, penilaian pribadi juga mempengaruhi peringkat karyawan, dan oleh karena itu hal ini memungkinkan adanya ambiguitas dalam evaluasi. Dalam penelitian ini diperkenalkan hybrid BWM-Fuzzy TOPSIS untuk mengevaluasi kinerja secara lebih realistis yang melibatkan 15 karyawan. BWM digunakan untuk menentukan bobot kriteria yang terdiri dari tiga kriteria dan sembilan subkriteria, sedangkan Fuzzy TOPSIS untuk pemeringkatan kinerja pegawai. Dengan mensimulasikan model optimasi min-max yang dirumuskan, bobot kriteria optimal dari yang tertinggi hingga yang terendah adalah semangat kerja karyawan (M), efektivitas kerja (E), dan produktivitas kerja (P). Bobot global pada prioritas tertinggi adalah loyalitas karyawan (M2), dan prioritas terendah adalah akurasi pekerjaan (P3). Penelitian ini telah mengevaluasi kinerja karyawan di perusahaan dengan cara yang lebih terstruktur dan dapat diandalkan. Karena secara spesifik dapat mengurutkan yang berkinerja terbaik hingga yang berkinerja terburuk, sedangkan pada metode saat ini, ada sembilan dari 15 karyawan yang tidak dapat diurutkan karena nilai total yang sama. Untuk studi lebih lanjut, analisis sensitivitas dapat dilakukan dengan mensimulasikan berbagai skenario untuk membawa lebih banyak informasi bagi pengambil keputusan ketika berhadapan dengan situasi tertentu. Abstract— The purpose of this study is to evaluate employee performance in a pipe fittings manufacturer situated in the region of Yogyakarta, Indonesia, using multi-criteria decision-making (MCDM) techniques. The manufacturer has currently conducted a performance evaluation; however, there have been two drawbacks in the current system assessment. Firstly, the current method cannot determine the priority of criteria. Secondly, personal judgment has also influenced the employee rankings, and therefore this allows ambiguity on evaluation. In this study, a hybrid BWM-Fuzzy TOPSIS is introduced to more realistically evaluate performance involving 15 employees. BWM is used to determine the weight of the criteria comprising three criteria and nine sub-criteria, while Fuzzy TOPSIS is for ranking employees’ performance. By simulating the formulated min-max optimization models, the optimal criteria weights from the highest to the lowest one are employee morale (M), job effectiveness (E), and job productivity (P), respectively. The global weight at the highest priority is employee loyalty (M2), and the lowest priority is job accuracy (P3). This research has evaluated employee performance in the company in a more structured and reliable way. It is because it can specifically rank the best performer to the worst performer, while in the current method, there have been nine out of 15 employees who cannot be ranked due to similar total value. For further study, a sensitivity analysis can be carried out by simulating various scenarios to bring more information for the decision-makers when dealing with a particular situation.

Abstract

Delivery activities have a great role for a business actor. However, delivery issues are there all the time. This was experienced by a noodle culinary SME that experienced delays in the delivery of various noodle raw materials and noodle toppings which caused noodle sales activities to be disrupted. In addition, these raw materials have a lifespan (without preservatives) so they must be delivered according to a predetermined schedule and hours. This research will solve this problem by minimizing delays through finding the shortest mileage delivery route. Because each delivery location has its own schedule and time window, the Nearest Neighbor method by paying attention to the time window is used. Based on the calculation results, each distribution route with the shortest distance was obtained, as evidenced by a reduction in the middle route by 0.23 km and the northern route by 5.88 km. In addition, this proposed delivery route was able to save fuel consumption on the middle route by 3% and the northern route by 10%. In terms of the workload aspect, car fleet drivers were also reduced by 31% and motorbike fleet drivers by 47%.

Abstract

Indonesia is an archipelagic country and has diverse natural resources that can be developed and increase the country’s foreign exchange and economy. This natural potential is often found in rural areas that are still developing. One of the village locations not having received much attention is Desa Beteng, Kabupaten Kulon Progo. Petatas and rabbit livestock are the potential and become a business opportunity for local villagers. The team took the initiative to provide socialization about using petatas as raw material for brownies and developing a rabbit livestock business. These things aim to open the horizons of local villagers as alternative livelihoods to improve their economy. The team identified the potential of the village, studied literature, collected data, and determined solutions. Based on these steps, socialization was carried out and it was found that the majority of villagers were not aware of the potential of the business used as a source of their income. The villagers also seemed enthusiastic and some of them who had started a rabbit livestock business inspired others. Likewise with making brownies from petatas, the villagers are serious and active in participating in this socialization. Monitoring these two things in the future needs to be done.

Abstract

A robust production system needs to be implemented across all business scales, including small-scale enterprises managed by community groups. This forms the foundation for the development of more competitive businesses. As reported in this paper, a community service program was elaborated to design a production system for a stagen weaving business group located in Moyudan, Sleman, Indonesia. To implement this production system, there are five main stages: situational analysis, production system design, workshop, implementation, and monitoring and evaluation. A pilot project was tested on four weavers with distinct characteristics. The results indicate that each of the four weavers produced different stagen patterns with significant revenue gains for weaver 1 and weaver 2 amounting to more than IDR 500.000 (360.24 meters and 237.43 meters, respectively). This program successfully achieved specific targets in line with the scope.

Abstract

Logistics service providers are the key stakeholder in Indonesian logistics activities that are growing significantly and face many challenges. In this research, a case study on a logistics service provider located in the city of Yogyakarta Indonesia is evaluated. The provider is currently experiencing rapid growth indicated by increasing delivery volume and scopes. However, optimal resource management has not been able to be adequately calculated, such as inefficient courier assignment and overloaded couriers' volume. Thus, this study aims to minimize total distances through optimal zone groups under several restrictions. An optimization approach is selected in this research by initially building a mathematical model using a standard form of linear programming. Then, the mathematical model is solved to generate minimum distances. The result indicated that the total minimum distances had been reached with considerable changes in delivery zone grouping, and the couriers' capacity was optimally utilized without overloaded capacity. These zone groups can be used as a reference for further research by taking into account some restrictions such as packages fluctuations as well as adding objective to minimize couriers' traveling time.
