Undang - undang no 26 tahun 2007 tentang penataan ruang secara tegas mengamanatkan 30% dari wilayah kota berwujud ruang terbuka hijau, 20% bersifat publik dan 10% bersifat privat. Pengalokasian ruang terbuka hijau ini ditetapkan dalam Peraturan Daerah tentang Rencana Tata Ruang Wilayah (RTRW) Daerah yaitu Pemerintah Kota Subulussalam. Pemerintah Kota Subulussalam perlu secepatnya menempatkan masalah ruang terbuka hijau sebagai salah satu isu penting dalam pembahasan program pembangunan berkelanjutan. Tujuan dari penelitian ini adalah memberi tambahan literasi melalui perspektif yang berbeda dari sisi akademis terhadap kawasan lindung yang telah di tetapkan dalam RTRW Kota Subulussalam sebagai perwujudan pola ruang terbuka hijau yang sistematis dan realistis. Metode yang digunakan dalam penelitian ini adalah kuantitatif deskriptif. Dalam hal ini metode integrasi Analitycal Hierarchy Process (AHP) digunakan agar dapat mengambil keputusan yang rasional dari beberapa kriteria tersebut dan Geographic Information System (GIS) sebagai pendukung keputusan dalam penentuan lokasi serta menggambarkannya pada sebuah peta zonasi. Berdasarkan hasil penelitian didapatkan bahwa dari 5 kecamatan di Kota Subulussalam, Kecamatan simpang kiri merupakan kecamatan yang memiliki kebutuhan ruang terbuka hijau paling tinggi. Hal itu dikarenakan 91,86% wilayah kecamatan simpang kiri memiliki kategori tingkat kebutuhan ruang terbuka hijau sedang hingga sangat tinggi yang berlokasi di area lapangan beringin

Parapat is the main gateway to Samosir Island and is often referred to as Parapat Tourism City. The presence of Lake Toba with its natural beauty makes the surrounding area a priority object and tourist attraction (ODTW) in North Sumatra. Currently, the Lake Toba area is designated as the National Tourist Destination (DPU) in North Sumatra. At the beginning of 2020, the world was shaken by the presence of the Covid-19 virus outbreak. The Indonesian government has also acted to contain the spread of Covid-19 by implementing the policy "Enforcement of Community Activities Restrictions Enforcement (PPKM)". The existence of these social restrictions has led to the stagnation of the tourism industry. The state of Indonesia's tourism economy, especially Parapat, remains volatile due to the Covid-19 pandemic. The purpose of this study is to investigate the economic situation of the tourist destinations of Parapat in the Covid-19 pandemic. This study uses a qualitative study with a descriptive approach. The data collection techniques used in this study include observational studies and literature studies. Looking at the economy of the tourism sector based on the WTO's Tourism Baseline Index for tourism destinations, there are three parameters: business investment in tourism, income from the tourism sector, and public spending. According to the survey, in 2020, the Covid-19 pandemic and the government's implementation of the Community Activities Restrictions Enforcement (PPKM) caused the decline of various economic sectors in the tourism industry

Perum Perumnas which was formed by the Central Government in providing housing for low-income groups of people, made a design with a uniform minimum standard, which in the end the house in a certain period of time will experience changes made by residents. Both the house and the perumnas environment will continue to experience changes every year, this is due to the increasing number of population and the alternation of residents in the perumnas. To find out what changes have occurred in Perumnas Helvetia, data processing and analysis is carried out descriptively and using cross tabulation (crosstab). The results of data processing and analysis show that the building area is the change most often carried out by the occupants of the house. For the area of land / land there is no change. The type of house also affects changes in building area, which means that where the building area changes, the type of house will also change. As for other perumnas environments, roads are the changes that have changed the most in perumnas, ranging from width to pavement.change in the residential enviroment, national housing

Penetapan suatu kawasan menjadi pusat pertumbuhan ekonomi skala nasional mendorong peningkatan aktivitas perkotaan, khususnya di kawasan metropolitan seperti Kawasan Mebidang (Medan, Binjai, dan Deliserdang). Kawasan Mebidang merupakan kawasan perkotaan dari Kawasan Mebidangro (Medan, Binjai, Deliserdang dan Karo) dicirikan dengan berbagai aktivitas perkotaan. Untuk menampung berbagai aktivitas perkotaan tersebut membutuhan lahan dan terus meningkat. Proses urbanisasi pun menjadi konsekuensi yang tidak dapat dihindarkan. Dampaknya, lahan produktif seperti lahan pertanian dan perkebunan bahkan kawasan lindung disekitar pusat kota diokupasi untuk pengembangkan permukiman atau lahan terbangun. Kota menjadi kawasan perkotaan yang luas dan melewati batas administrasi. Selain berdampak positif, perkembangan permukiman yang luas menghadapi persoalan penyediaan prasarana dan sarana perkotaan yang cukup dan berkualitas. Umumnya pemerintah daerah tidak mampu mengimbangi penyediaan prasarana dan sarana tersebut. Tujuan penelitian adalah menjelaskan perkembangan kawasan permukiman di Kawasan Mebidang dalam kurun waktu 10 tahun (2005-2014). Penelitian ini menggunakan metode komparasi penggunaan lahan pada tahun 2005 dengan tahun 2014 untuk melihat perubahan penggunaan lahannya. Untuk melihat penggunaan lahan tersebut dengan cara menginterpretasi data citra pada tahun 2005 dan tahun 2014. Dari perbandingan tersebut disimpulkan terjadi perkembangan kawasan permukiman sebesar 132,76%. Menghadapi perkembangan ini dibutuhkan kerjasama antar pemerintahan dalam pengelolaan kawasan permukiman berbasis regional untuk meminimalkan eksternalitas negatif sekaligus meningkatkan efisiensi.

Flood risk assessment plays a crucial role in determining flood hazard zones and formulating effective mitigation strategies. Using a multi- criteria decision support system, this study focuses on evaluating the flood risk index within the Bolon Watershed (DAS Bolon). Geographic Information Systems (GIS) were employed as an effective disaster mitigation tool to provide comprehensive geospatial data. The research integrates the Cellular Automata–Markov Chain (CA–MC) model using the MOLUSCE plugin in QGIS to spatially project land-use change analysis, the Analytical Hierarchy Process (AHP) to determine variable weights influencing flood risk, and Weighted Multi-Criteria Analysis (WMCA) for spatial flood zonation assessment. Between 2017 and 2021, significant land-cover changes occurred in the Bolon Watershed, with 67.55 km² converted into residential areas.

Between 2017 and 2021, significant land-cover changes occurred in the Bolon Watershed, with 67.55 km² converted into residential areas. Forest deforestation began in 2017 and is projected to continue until 2033, potentially disrupting the hydrological cycle and intensifying flood-prone zones. As a result, the flood-prone residential area increased markedly from 1.4% (2017) to 2.89% (2021) and is projected to reach 4.74% by 2033, with an average annual increase of 0.21%. This study underscores the importance of improved land-cover management to mitigate flood zonation in the Bolon Watershed. It also emphasizes the need for strict enforcement of spatial planning and zoning regulations, as well as enhanced monitoring and legal measures against land-use conversion particularly in flood-prone and water recharge areas

City dynamics must be seen as a complex system with varying degrees of non-linear interaction of space and time. Cities are not constantly growing. At some point it will shrink and may die. Many factors cause such as globalization, suburbanization, post-socialism, and changes in demographic structure and so on. In many studies, the shrinking city phenomenon is mostly carried out in developed countries. However, developing countries are not impossible to experience this phenomenon. Each city experiencing the shrinking city phenomenon has different characteristics. In developing countries, local government policies that depend on various aspects of central government policies have a level of vulnerability to shrinking city phenomenon. Changes in central government policy on the smal city have an impact on changes in the economic structure of the city. Moreover, limited resources and the absence of small city innovation make it increasingly difficult for cities to grow.

In 2021, the service coverage of PDAM Tirtanadi’s water supply system reached 73.3%. To further improve the service capacity, a new raw water source was developed through the construction of the Mebidang Regional Water Supply System (SPAM), which draws water from the Bingei River in Binjai City. The PDAM Tirtanadi branches directly affected by this change in raw water source include the Sei Agul and Diski branches. This study aims to evaluate customer satisfaction levels with the water product quality and service performance of the Mebidang SPAM at PDAM Tirtanadi. The methods employed include the Customer Satisfaction Index (CSI) and Importance and Performance Analysis (IPA). Data were collected through questionnaires distributed to both existing customers and new service connections at the Diski and Sei Agul branches of PDAM Tirtanadi. The results showed that customer satisfaction levels were as follows: long-term customers at the Diski branch scored 83.56%, new connections at Diski 83.57%, long-term customers at Sei Agul 82.78%, and new connections at Sei Agul 92.26%. These results indicate that both long-term and new customers at the Diski and Sei Agul branches are generally satisfied with the overall service quality. Based on the IPA results, the main priority for improvement at the Diski branch concerns the imbalance between the cost paid by customers and the volume of water received. Meanwhile, for the Sei Agul branch, variables categorized as low performance and low importance but still of lower priority include PDAM’s responsiveness to customer requests, such as for new connections or meter repairs.

Public construction materials laboratories play a vital role in safeguarding infrastructure quality and public safety. Although ISO/IEC 17025:2017 is widely adopted as a quality management system, its actual influence on strategic performance in government laboratories is not well understood. This study evaluates the implementation of ISO/IEC 17025:2017 at a provincial government testing laboratory in North Sumatra, Indonesia, by integrating it with the Balanced Scorecard (BSC) framework. A mixed-methods approach was used involving 60 participants—30 internal personnel and 30 external users—through surveys, interviews, and direct observation. The BSC evaluation produced a performance score of 77.35%, categorized as satisfactory, with the strongest contribution from customer and financial perspectives. This study introduces an integrated evaluation framework tailored to public laboratories, bridging quality compliance with strategic governance. The results highlight the importance of aligning technical quality with institutional accountability, offering a practical pathway for improving performance and public trust in government testing services.
