Judul: Business Model Development Strategy in the Tourism Sector (Case Study of Taman Wisata Iman, Dairi)
Abstrak: Indonesia memiliki banyak destinasi wisata yang menarik perhatian wisatawan, baik lokal maupun mancanegara. Taman Wisata Iman (TWI) merupakan gabungan konsep wisata alam dan wisata buatan bertema rohani yang menjadi salah satu sumber Pendapatan Asli Daerah (PAD) Kabupaten Dairi dan sedang mengalami penurunan jumlah pengunjung dalam beberapa tahun terakhir. Oleh karena itu, perlu dirumuskan strategi pengembangan usaha untuk memperbaiki model bisnis sehingga tujuan perusahaan dapat tercapai secara maksimal. Tujuan dari penelitian ini adalah (1) mengidentifikasi model bisnis yang diterapkan oleh TWI saat ini dengan metode Business Model Canvas (BMC), (2) menganalisis faktor kekuatan dan kelemahan, serta peluang dan ancaman (SWOT) dari setiap elemen BMC TWI, dan (3) merumuskan strategi pengembangan bisnis yang sesuai bagi TWI. Pengumpulan data dalam penelitian ini menggunakan teknik observasi, wawancara mendalam dan studi pustaka. Penelitian ini menggunakan pendekatan kualitatif dengan metode analisis BMC dan analisis SWOT. Hasil dari penelitian ini adalah berupa rekomendasi strategi yang dapat diimplementasikan sebagai upaya meningkatkan jumlah pengunjung sehingga bisnis pariwisata TWI dapat mengalami kemajuan., Indonesia has many tourist destinations that attract the attention of tourists, both local and foreign. Taman Wisata Iman (TWI) is a combination of the concept of nature tourism and artificial tourism with spiritual-themed, which is one of the sources of Dairi Regency's Original Local Government Revenue (PAD) and has experienced a decline in the number of visitors in recent years. Therefore, it is necessary to formulate a business development strategy to improve the business model so that the company's goals can be achieved optimally. The aims of this study are (1) to identify the business model currently applied by TWI using the Business Model Canvas (BMC) method, (2) to analyze the strengths and weaknesses, as well as opportunities and threats (SWOT) of each element of TWI's BMC, and ( 3) to formulate a suitable business development strategy for TWI. Collecting data in this study using observation techniques, in-depth interviews and literature study. This study uses a qualitative approach with BMC analysis and SWOT analysis methods. The results of this study are in the form of strategic recommendations that can be implemented as an effort to increase the number of visitors so that TWI can progress.

Judul: Economic Impact and Carrying Capacity Analysis of the Taman Wisata Iman in Dairi Regency Due to the Covid-19 Pandemic
Abstrak: Pandemi Covid-19 berdampak terhadap penutupan kawasan wisata sementara waktu dan terjadinya penurunan jumlah kunjungan yang bersifat fluktuatif, dimana berdampak terhadap unit usaha dan tenaga kerja di kawasan tersebut. Tujuan dari penelitian ini adalah (1) menganalisis dampak ekonomi Taman Wisata Iman, Kabupaten Dairi akibat pandemi Covid-19; (2) menghitung daya dukung wisata di kawasan Wisata Taman Wisata Iman; (3) menganalisis strategi pengembangan kawasan Taman Wisata Iman. Metode yang digunakan adalah, multiplier effect, daya dukung fisik (PCC), analisis deskriptif. Hasil penelitian menunjukkan sebelum dan saat adanya pandemi Keynesian Income Multiplier di TWI kurang dari satu, artinya dampak yang dirasakan oleh masyarakat lokal masih rendah. Namun, Ratio Income Multiplier Tipe I dan Tipe II lebih besar dari satu yang menandakan pengeluaran wisatawan sudah berdampak dan berkontribusi dengan baik terhadap pendapatan unit usaha dan tenaga kerja, baik itu sebelum dan saat pandemi Covid-19. Daya dukung kawasan TWI sebelum dan saat pandemi Covid-19 mengalami under carrying capacity, baik itu pada saat weekday, weekend dan musim libur. Pengembangan kawasan TWI dilakukan dengan tahap sarana prasarana, promosi atau iklan dan menyesuaikan kondisi carrying capacity., The Covid-19 pandemic has had an impact on the temporary closure of tourist areas and a decrease in the number of fluctuating visits, which has had an impact on business units and workforce in the area. The purposes of this research are (1) to analyze the economic impact of Iman Tourism Park, Dairi Regency due to the Covid-19 pandemic; (2) calculate the carrying capacity of tourism in the Taman Wisata Iman Tourism area; (3) analyzing the development strategy of the Faith Tourism Park area. The method used is multiplier effect, physical carrying capacity (PCC), descriptive analysis. The results of the study show that before and during the pandemic, the Keynesian Income Multiplier in TWI was less than one, meaning that the impact felt by the local community was still low. However, the Type I and Type II Income Multiplier Ratio is greater than one, which indicates that tourism expenditure has had an impact and contributed to both business unit and workforce income, both before and during the Covid-19 pandemic. The carrying capacity of the TWI area before and during the Covid- 19 pandemic experienced a lack of carrying capacity, both on weekdays, weekends and the holiday season. The development of the TWI area is carried out with the stages of infrastructure, promotion or advertising and adjusting the carrying capacity conditions

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
