Abstract

As part of Indonesia’s capital relocation plan to East Kalimantan, Balikpapan plays a critical role as a supporting city, facing opportunities and challenges in infrastructure, economic stability, and public services. This study forecasts two key economic indicators: monthly inflation and annual Gross Regional Domestic Product (GRDP), using Error, Trend, Seasonal (ETS) and Autoregressive Integrated Moving Average (ARIMA) methods. For monthly inflation, the SARIMA(0,1,1)(1,0,0)12 model outperforms ETS(A,N,N) with a lower RMSE, providing higher accuracy in capturing inflation dynamics. For annual GRDP, both ETS(A,N,N) and ARIMA(0,0,0) yield similar accuracy, with ARIMA slightly better. These findings support data-driven planning to maintain price stability and foster economic growth. Accurate projections ensure Balikpapan’s readiness as a sustainable, resilient city, aligning with SDG 8 (Economic Growth) and SDG 11 (Sustainable Cities and Communities).

Abstract

Abstrak: Terdapat beberapa permasalahan yang diidentifikasi di wilayah mitra antara lain letak lokasi terutama di fasilitas umum seperti posyandu, rumah Ketua RT menjadi kendala bagi navigasi pendatang baru yang dapat menghambat partisipasi warga dalam program atau kegiatan RT, serta keadaan jalan pada wilayah mitra terdapat banyak gang sempit dan perempatan dimana hal tersebut dapat mengurangi penglihatan terhadap jalan lainnya, terutama ketika keadaan sedang ramai sehingga dapat menyebabkan terjadinya potensi kecelakaan lalu lintas. Dari permasalahan tersebut, perlu dilakukan tindakan yang tepat untuk meningkatkan sarana prasarana, keselamatan dan mengurangi risiko kecelakaan lalu lintas. Tujuan dari kegiatan pengabdian masyarakat ini adalah meningkatkan pembangunan sarana prasarana wilayah mitra, yang dinilai perlu pembenahan. Beberapa kegiatan yang dilaksanakan untuk peningkatan sarana wilayah mitra yaitu pengadaan denah lokasi RT, penanda pembatas RT, pengecatan fasilitas umum seperti posyandu, serta pemasangan convex mirror. Dari evaluasi kegiatan yang telah dilakukan melalui survey kepada warga wilayah mitra, diketahui bahwa sebagian besar masyarakat memberikan penilaian positif terkait pengadaan sarana prasarana dan perbaikan posyandu dimana 83% dan 72% masyarakat menilai kegiatan tersebut sangat baik.Abstract: There are several problems identified in partner areas, including the location, especially in public facilities such as posyandu, the RT Head's house being an obstacle for navigation for new arrivals which can hinder residents' participation in RT programs or activities, as well as the condition of the roads in the partner area, there are many narrow alleys and intersections where this can reduce visibility of other roads, especially when it is busy, which can lead to potential traffic accidents. Based on these problems, appropriate actions need to be taken to improve infrastructure, safety and reduce the risk of traffic accidents. The aim of this community service activity is to increase the development of infrastructure in partner areas, which are deemed to need improvement. Some of the activities carried out to improve facilities in partner areas include providing RT location plans, RT boundary markers, painting public facilities such as posyandu, and installing convex mirrors. From the evaluation of activities that have been carried out through surveys with residents of partner areas, it is known that the majority of people give positive assessments regarding the provision of infrastructure and improvements to posyandu, where 83% and 72% of people assess these activities as very good.

Abstract

This research focuses on investigating the economy of the new capital buffer zone by identifying and clustering its leading sectors in GRDP (Gross Regional Domestic Product) of East Kalimantan. The identification of a region’s leading sector through LQ (Location Quotient) index has proven to be effective. In addition, k-means clustering and Self-Organizing Maps (SOM) are adopted to provide comprehensive insights. The results show that LQ index quickly identifies the main sectors in each district of East Kalimantan. In addition, the kmeans clustering has better performance than SOM based on the Silhouette coefficient. This meticulous analysis confirms the existence of two distinct clusters, one including eight members and the other consisting of only two. Anticipating future research endeavours, the exploration of various approaches for constructing clusters, encompassing both hierarchical and non-hierarchical approaches, provides the potential to enhance the performance of clusters. By investigating this structure, a more comprehensive comprehension of the economic framework of East Kalimantan can be achieved, as well as its potential role as a buffer for the capital region.

Abstract

This community service program aims to strengthen the capacity of micro, small, and medium enterprises (MSMEs) in branding, product design, and digital marketing in order to enhance their business competitiveness. The program was implemented through a series of training sessions and mentoring activities involving 57 MSME participants. It consisted of three main components: (1) branding and business preparation, (2) product and packaging design using simple digital tools, and (3) social media–based marketing for digital promotion. Evaluation was conducted using pre- and post-training tests, structured questionnaires, and visual documentation of product packaging. The data were analyzed using descriptive statistics and comparative analyses of participants’ test scores and design outputs. The results indicate substantial improvements in participants’ understanding of branding principles, design aesthetics, and digital literacy. Quantitatively, the average test score increased from 9.1 in the pre-test to 10.0 in the post-test, and many participants successfully redesigned their product packaging and began using social media more systematically for promotional purposes. As a result, MSME owners developed clearer product identities, more attractive packaging, and more consistent online engagement. Overall, the program demonstrates that short-term, community-based interventions can effectively enhance MSME competitiveness and digital readiness while supporting sustainable local economic growth. These findings underscore the importance of integrating creativity, technology, and community participation in MSME empowerment initiatives.
