Sorong is a very strategic city because it is the doorway and stopover of papua province. Sorong is also well known as city of trade and services industry because it is surrounded by very potential natural resources districts areas that can open the opportunities for domestic and foreign investment. Special Economic Zones (SEZ) are areas with certain limits to carry out the economic functions and obtain certain facilities. Those areas are prepared to maximize industrial activities, export, import, and other economic activities that have high economic value. SEZ sorong which is located in the Sele Strait provides geo-economic advantages namely the potential in the fisheries and sea transportation sectors. This location is also very strategic for development of logistic industry, agroindustry, and mining, so that SEZ sorong was developed by the activities of those three potentials and predicted to be able produce investment of Rp 32.2 trillion in 2025. This study aims to examine and analyze the effect of SEZ Sorong on economic growth of West Papua Province which was analyzed using qualitative descriptive method and to identify significant factors that effecting economic growth in West Papua with multiple linear regression analysis. Predictive variables used in this study are service (X1), industry (X2), labor (X3), service capital (X4), trade (X5), Export (X6) and economic growth as variable Y. The result of this study shows that SEZ is very influential positively on the economic growth of West Papua Province.

In flood-prone areas, coordination between parties in disaster risk reduction activities is very important. This is because disasters will directly impact the disruption of people’s lives and livelihoods, as well as hinder the process of sustainable development. This study aims to develop a public coordination scheme for flood risk reduction activities based on public resources available in North Luwu Regency. Public resources come from government agencies and the potential of the community available in North Luwu Regency with their respective tasks at the stage before, during, and after the disaster. Public coordination is expected to support the implementation of sustainable development based on disaster risk reduction in North Luwu Regency. The preparation of the public coordination scheme was preceded by a geospatial flood hazard assessment based on the characteristics of the Rongkong Downstream Watershed using a Geographic Information System (GIS). The results of the assessment form the basis for the implementation of the preparation of public coordination for DRR. North Luwu Regency is dominated by coastal land units bordering Bone Bay, plains to mountains. High rainfall, critical land use, and low-lying settlements cause the research area to be in a high to very high risk zone experiencing flooding. Sustainable development can run effectively if its implementation is based on disaster risk reduction policies with public coordination. Public coordination is carried out between government agencies and the community, who work together according to their respective roles and tasks at the pre-, during, and post-disaster stages. The results of the study indicate that more sector involvement is needed in the pre-and post-disaster stages. This indicates that public coordination before a disaster is risk prevention and reduction activity that should be prioritized in the implementation of development before hampering the sustainability of development.

Indonesia's current potato cultivation areas are mainly in the highlands (1 000 m above sea level – a.s.l.). However, there are obstacles to potato cultivation in the highlands, including erosion, declining land productivity, limited area, and high production costs (i.e. labour wages, fertilisers, and pesticides). This study was aimed at analysing the effects of both an ethanol application and moderate altitudes on the potato production and quality. This study was conducted at the Horticulture Seed Station in the Ulu Ere subdistrict, Bantaeng Regency, South Sulawesi, Indonesia. A split randomised plot design with two factors was used. The main plots were set at two elevation levels: 500 and 700 m a.s.l. The split plots were subjected to the addition of four ethanol concentration levels: 0, 10, 20, and 30%. The results showed that the ethanol application did not significantly affect the potato growth at the moderate elevation, except for the tuber diameter. Moreover, the 20% ethanol concentration produced better results than the 0% ethanol concentration. The application of 10% ethanol at an altitude of 700 m a.s.l. and 30% ethanol at an altitude of 500 m a.s.l. resulted in the best growth and yield among the studied treatments.

Kecamatan Somba Opu secara umum dan Kelurahan Tompobalang secara khusus mengalami perkembangan yang cukup progresif setiap tahun akibat meningkatnya populasi penduduk. Perkembangan wilayah studi yang signifikan berdampak pada kuantitas produksi sampah yang juga makin meningkat. Peningkatan kuantitas sampah tidak dibarengi dengan kinerja pengelolaan sampah yang baik sehingga disisi lain memunculkan gejala-gejala penurunan kualitas lingkungan. Sehingga untuk mengetahui hal itu, perlu diketahui kinerja penelolaan sampah yang ada dan hubungannya terhadap penurunan kualitas lingkungan di wilayah studi. Tujuan pertama penelitan ini adalah mengetahui pengelolaan sampah yang dianalisis menggunakan metode tabulasi silang/crosstab dengan uji chi-kuadrat pearson, menggunakan variable teknik operasional (X1), kelembagaan (X2), pembiayaan (X3), peran serta masyarakat (X4), dan regulasi (X5). Tujuan kedua dan untuk mengetahui partisipasi masyarakat terhadap pengelolaan persampahan dengan menggunankan metode skala likert. Hasil penelitian menunjukkan bahwa partisipasi masyarakat dalam pengelolaan sampah yang diukur dengan variable yang telah disebutkan masih berada pada kategori kurang baik. Selain itu, kinerja pengelolaan sampah yang masih kurang tersebut berpengaruh signifikan namun hubungannya lemah terhadap penurunan kualitas lingkungan yang terjadi di wilayah studi. Somba Opu district in general and Tompobalang sub-district in particular is experiencing a fairly progressive development every year due to the increasing population. The significant development of the study area has an impact on the quantity of waste production which is also increasing. The increase in the quantity of waste is not accompanied by good waste management performance so that on the other hand it raises symptoms of a decrease in environmental quality. As such, to know this, it is necessary to know the performance of existing waste management and its relationship to environmental quality degradation in the study area. The first objective of this research is to know the waste management which is analyzed using cross tabulation method with Pearson chi-square test, using operational technique variables (X1), institutional (X2), financing (X3), community participation (X4), and regulations (X5). The second objective is to determine community participation in solid waste management using the Likert scale method. The results showed that community participation in waste management as measured by the variables mentioned above was still in the poor category. In addition, the performance of waste management that is still lacking has a significant but weak relationship with the decline in environmental quality that occurs in the study area
