The geographical condition of Sungai Pisang Village located on the coastal fringe and not too far from the famous island tourism which potential in West Sumatera becomes an opportunity for the people of Sungai Pisang, especially the fishermen to increase their standard of living. But in reality, the outsiders in the Bungus area are more likely to take advantage of the opportunity because of their location close to the city center. The tourists can only be seen from afar by biduk fishermen of Sungai Pisang. Most tourists prefer to use Tour and Travel services from Bungus area. Biduk fishermen are only bringing few tourists to the island tour even though the price offered is much cheaper. Based on preliminary study, there are problems such as the lack of knowledge of the fisherman on the effective product marketing strategy. So far, there are no marketing tools to promote the transportation services of biduk fisherman to the island tourism in the Sungai Pisang broadly. Therefore, it is necessary to design a marketing information system for island tourism biduk. The marketing information system is a mobile web-based designed using PHP programming language and supported by the MySQL database. The information marketing system is expected to increase the number of tourists who use the island tourism biduk as an effort to increase the sustainable fishermen's economy.

Kondisi geografis Kelurahan Sungai Pisang yang terletak di pinggiran pantai dan tidak terlalu jauh dari potensi wisata pulau yang terkenal di Sumatera Barat menjadi peluang bagi masyarakat Sungai Pisang khususnya nelayan biduk untuk meningkatan taraf hidupnya. Namun kenyataannya, pihak luar yang berada di daerah Bungus justru yang lebih memanfaatkan peluang tersebut karena lokasinya yang dekat dengan pusat kota. Wisatawan yang ramai hanya bisa dilihat dari jauh oleh nelayan biduk Sungai Pisang ini. Kebanyakan wisatawan lebih memilih untuk menggunakan jasa Tour and Travel dari Bungus. Nelayan biduk hanya membawa sedikit wisatawan saja menuju wisata pulau walaupun harga yang ditawarkan jauh lebih murah. Berdasarkan analisis situasi, permasalahan tersebut terjadi karena kurangnya pengetahuan nelayan biduk tentang strategi pemasaran produk yang efektif. Selain itu, biduk yang digunakan masih sangat sederhana, belum memperhatikan aspek keselamatan dan kenyamanan penupang. Sejauh ini belum adanya sarana pemasaran produk untuk mempromosikan jasa transportasi biduk wisata pulau dari nelayan biduk di Sungai Pisang secara luas. Kegiatan ini bertujuan untuk memberikan pengetahuan dan penjelasan kepada nelayan biduk mengenai strategi pemasaran produk yang efektif untuk meningkatkan jumlah wisatawan pengguna biduk wisata pulau, merancang desain biduk yang menarik dan melengkapi biduk dengan fasilitas keselamatan dan kenyamanan penumpang untuk meningkatkan kepuasan wisatawan terhadap jasa transportasi biduk, merancang dan membuat media promosi berupa website pemasaran biduk yang dihubungkan dengan berbagai media sosial untuk memperkenalkan secara luas biduk wisata pulau di Sungai Pisang, dan memberikan pengetahuan dan keterampilan kepada nelayan biduk dalam menggunakan dan mengelola website sehingga dapat digunakan secara berkelanjutan.

One of the pivotal aspects of a company lies in its supply chain. The company must effectively and efficiently manage their supply chains to support production quality, achieve organizational goals, and ensure customer satisfaction. This research aims to determine the key performance indicators (KPIs) for the crumb rubber processing industry and provide suggestions for improving its supply chain performance. Supply chain performance measurement was conducted using the Supply Chain Operations Reference (SCOR) model in conjunction with the Analytical Hierarchy Process (AHP) method to determine the weights of the KPIs. The research found that the overall supply chain performance score for the crumb rubber company was 84.92, categorizing it as "Good." However, among the 26 Key Performance Indicators (KPIs) identified, three indicators (i.e. production of defective products, consumer complaints, and returns of defective products) fell into the "Poor" category. Hence, it is crucial for crumb rubber industry stakeholders to address these three criteria to enhance supply chain performance.

In Indonesia, the cattle agricultural business is one of the most significant food commodities for comply nutritional needs. The variable availability of cattle supplies is a challenge that the Padang City Agriculture Service must tackle. As a result, to establish the state of food security in Padang City, food security indicators must be calculated and analyzed. Food Security Quotient (FSQ) approach was used in this study to map the logistical network and beef food security. Following that, an information system based on a Geographic Information System (GIS) was created to represent the flow of the beef supply chain in Padang City. It was discovered from direct observations beef supply chain network in Padang City comprises of a fresh beef and a frozen beef supply chain. Beef suppliers from other regions, local breeders, feed lotters, slaughterhouses, wholesalers, retail traders, hotel / supermarket /restaurant/ catering consumers, rendang processing industry consumers (MSMEs), home consumers small-scale dining, and household consumers are all involved in the fresh beef supply chain. The analysis of the level of food security in Padang City revealed that three sub-districts were in the secure state, three were in a moderate state, and five were in a vulnerable state. The developed GIS is supposed to aid decision making in Padang City on food security predictions.

This study is motivated by the importance of understanding the factors influencing the net profit of Regional Owned Enterprises (BUMD) in West Sumatra Province, particularly in the context of the number of employees and the number of companies. The purpose of this research is to analyze the effect of the number of employees and the number of companies on the net profit of BUMD using multiple linear regression methods. The data used in this study were sourced from the Central Statistics Agency (BPS) for the period from 2013 to 2022. The results of the analysis indicate that the regression model is overall significant with an R2 adjusted value of 0,537, meaning that 53,7% of the variation in net profit can be explained by the number of employees and the number of companies. However, the individual effects of the number of employees and the number of companies on net profit are not statistically significant at the 95% confidence level. The conclusion of this study is that the number of employees and the number of companies collectively influence the net profit of BUMD, although the impact of each variable is not strong enough individually.

Peran UMKM dalam pertumbuhan ekonomi di Indonesia sangatlah penting karena banyaknya tenaga kerja yang terserap pada sektor ini. Pasca Covid-19 hingga saat ini, UMKM semakin berkembang dan berinovasi. Salah satu cara pemerintah untuk menghidupkan kembali laju pertumbuhan ekonomi Indonesia adalah dengan menekan laju inflasi dan menurunkan suku bunga. Jika dilihat dari hasil penelitian yang ada, inflasi dan suku bunga memiliki pengaruh yang signifikan terhadap pertumbuhan UMKM. Penelitian lainnya mengungkapkan bahwa jumlah angkatan kerja memiliki pengaruh yang signifikan terhadap kenaikan jumlah UMKM. Penelitian ini ingin melihat pengaruh dari Pertumbuhan Angkatan Kerja, Inflasi dan Suku Bunga terhadap Jumlah UMKM dengan metode regresi linier berganda dimana analisis regresi linear berganda dilakukan untuk mengetahui arah dan seberapa besar pengaruh variabel independent (bebas) terhadap variabel dependen (terikat). Penelitian ini berhasil mendapatkan persamaan regresi liner berganda untuk menentukan Jumlah UMKM (Y) berdasarkan Jumlah Angkatan Kerja (X1), Inflasi (X2) dan Suku Bunga (X3) yaitu Y = 884672 - 1,6X1 - 401729,7X2 - 2239731,6X3. Dari hasil analisis regresi yang dilakukan, dapat disimpulkan bahwa secara simultan atau bersama-sama, Angkatan Kerja (X1), Inflasi (X2) dan Suku Bunga (X3) berpengaruh signifikan terhadap Jumlah UMKM (Y) dimana nilai R square = 93,84%. Sementara sisanya 6% dipengaruhi oleh variabel diluar dari yang diteliti. Jika dilihat secara terpisah, Angkatan Kerja (X1) dan Suku Bunga (X3) secara signifikan memberikan pengaruh terhadap Jumlah UMKM dimana P-value untuk Angkatan Kerja 0,0029 < 0,05 dan P-value untuk Suku Bungan 0,022 < 0,05. Sedangkan variabel Inflasi (X2) cukup memberikan pengaruh yang signifian terhadap Jumlah UMKM karena nilai dari P-value sedikit diatas 0,05 yaitu 0,06.
