Forests are one of the natural resources that provide many benefits for the welfare of living things.The dense population causes people to depend more on forest resources. One of them is illegal logging.Various strategies to control forest damage due to illegal logging have been carried out, namely by directhandling to improve damaged conditions while preventing the recurrence of forest damage. The purposeof this research is to build a mathematical model of forest resource damage control strategies due toillegal logging, determine assumptions, formulate the model, and conduct analysis and problem solvingincluding: determining the equilibrium point, determining the stability analysis of the equilibrium point,and conducting numerical simulations of the equilibrium point. The last step is to interpret the results ofthe analysis obtained and make conclusions. Based on the research and simulation results of the model,it can be concluded that taking into account the variable of forest resource damage control strategydue to illegal logging, the result shows that if the density of forest resources has been affected by thedisturbance of population density around the forest, it is necessary to have a forest resource damagecontrol strategy in order to compensate for the people around the forest who do a lot of illegal logging.In order to maintain the forest so that the forest does not quickly become extinct and can overcomedrought, prevent flooding, maintain groundwater quality, protect animals, reduce air pollution, climatecontrol, reduce dust particles, prevent the greenhouse effect, supply natural fertilizers, prevent erosion,and maintain springs.

Pembangunan berbasis pengembangan wilayah memandang pentingnya keterpaduan sektoral, spasial serta keterpaduan antar pelaku-pelaku pembangunan pada suatu wilayah. Keterpaduan sektoral menuntut adanya keterkaitan fungsional dan sinergis antar sektor-sektor pembangunan, sehingga program-program pembangunan sektoral selalu dilaksanakan dalam kerangka pembangunan wilayah. Tujuan Penelitian ini adalah untuk menganalisis struktur ekonomi melalui permintaan antara dan permintaan akhir Provinsi Nusa Tenggara Timur menggunakan pendekatan Input Output. Hasil analisis menunjukan bahwa Penelitian ini menemukan bahwa struktur permintaan antara didominasi oleh sektor pertanian yang memberikan kontribusi sebesar 40%. Struktur konsumsi rumah tangga tertinggi berada pada sektor industri dan transportasi, serta jasa pendidikan dan pertanian

Regional economic disparities and fragmented inter-island linkages remain key challenges in East Nusa Tenggara (NTT), one of Indonesia’s archipelagic provinces with diverse resource endowments. This study analyzes the structure and dynamics of NTT’s regional economy by identifying its leading sectors through intersectoral linkage analysis, estimating the magnitudes of multiplier effects, and examining spillover effects across the province’s major islands. The research utilizes the 2016 Input–Output Table of NTT Province and the accumulated Gross Regional Domestic Product (GRDP) data of regencies and cities across the Timor, Flores, and Sumba islands for the 2016–2023 period. Analytical methods include linkage analysis, multiplier effect estimation, and the Vector Error Correction Model (VECM). The results show that agriculture, manufacturing, electricity, trade, and transportation constitute the leading sectors due to their strong forward and backward linkages. At the same time, agriculture and manufacturing also generate the largest multiplier effects. These sectors further create significant inter-island spillover effects, characterized by spread effects between Sumba–Timor, Sumba–Flores, and Timor–Sumba, and backwash effects between Timor–Flores and Flores–Sumba. The findings highlight that strengthening productive linkages in agriculture and manufacturing is vital for enhancing spatial equity and promoting inclusive regional growth. Conceptually, this study contributes to the literature by integrating intersectoral, multiplier, and spillover analyses to explain spatial economic interdependence in archipelagic regions and by offering practical policy implications for fostering sustainable inter-island integration in NTT Province.
