Household waste still becomes a national problem as it causes air, soil and water pollution and disturbs aesthetics. For this reason, comprehensive and integrated waste management from upstream to downstream needs to be carried out in order to provide economic and health benefits for the community and be safe for the environment. Organic waste processing can be performed using black soldier fly (BSF). BSF is a type of fly that can eat household organic waste, making this fly is widely used as an alternative to processing organic waste, especially from households. This research uses an experimental method of cultivation scale and produces a by-product in the form of solid fertilizer which then compared with the Decree of the Minister of Agriculture of the Republic of Indonesia No. 261 of 2019 concerning Organic Fertilizer, Biological Fertilizer and Soil Improvement. From laboratory tests, the parameters of C-organic, C/N, by-products, pH, macronutrients, heavy metals, micronutrients, and biological analysis met the quality standards.

Lake Toba area has been designated a National Strategic Area, which is a priority spatial planning area. The Simanindo Area is a sub-district in Samosir Regency which is an island in the middle of Lake Toba, North Sumatra, Indonesia. Lake Toba's current condition has been polluted by organic contamination and high free chlorine. In addition, the existence of fish farming activities or floating net cages that contribute to the contamination of phosphorus by 0.78 mg/l and free chlorine by 0.84 mg/l into Lake Toba which resulted in the need for studies on the carrying capacity and environmental capacity. Land carrying capacity can be calculated by comparing the availability of land with land requirements. While the carrying capacity of water can be calculated by comparing the availability of water with water requirements or using the Thornwaite Mather Water Balance method. Land Capacity can be calculated by the Land Endurance Unit. While the Capacity of Waters can be calculated by STORET analysis or calculation of domestic waste pollution load. The existence of a massive development plan for Simanindo area and rapid population growth is projected to cause the Land Support Capacity of the Simanindo Priority Zone to be conditionally safe in 2040. Water Carrying Capacity experienced a deficit in the atmosphere in July after being calculated with the Thornwaite Mather Water Balance. In addition, the Capacity of Water Bodies is also in the Status of Severe Pollution according to the STORET Method.

Post-disaster recovery had to be measured to determine the level of success of the recovery process whether it has returned to pre-disaster condition or conditions that are better than before the disaster or even worse than before the disaster. This study aimed to analyze the social and economic recovery of disaster-affected communities in order to support sustainable regional programs. This study used qualitative research method with a case study research design. The results of the study showed that social recovery in 3 years after the Tsunami, namely in 2021, is 100.08% with the indicator of recovered. Meanwhile, the economic recovery up to 3 years after the Tsunami, namely in 2021, at 99.59% has not yet reached the recovery indicator. The recovered category is based on the calculation results with numbers above 100%. The conclusion of this research was that the effective social and economic recovery will support sustainable regional development because community resilience will be formed. The process of social and economic recovery, the current social condition of the community has recovered on average and the economic condition of the community is nearing recovery, with minimal central government programs. This was due to the resilience of local governments and communities. A strong social and economic community will support the creation of the principle of "build back better and safer", so that people's lives will be better and safer than before the disaster occurred.

Indonesia secara geografis memiliki keragaman curah hujan yang cukup besar antardaerah. Angin merupakan salah satu parameter untuk menentukan kondisi iklim suatu wilayah. Salah satu faktor penyebabnya dipengaruhi oleh sirkulasi angin zonal (Hadley) dan meridional (Walker). Aktifitas ENSO juga mempengaruhi sirkulasi angin yang masuk di wilayah Indonesia. Penelitian ini bertujuan untuk mengetahui Respons Sirkulasi Angin Zonal dan Meridional Terhadap Curah Hujan di Kabupaten Jayapura. Metode penelitian ini memanfaatkan data hujan bulanan Stasiun Klimatologi Jayapura tahun 1991-2010, Indeks Nino 3.4 NOAA, dan data angin zonal dan meridional ketinggian 10 meter ECMWF dengan resolusi spasial 0.125°x0.125° periode 1991-2010. Melalui analisis ini didapat, wilayah Jayapura memiliki tipe hujan monsunal dengan karakteristik lokal yang kuat. Hal ini juga menyebabkan tidak ada pergeseran musim saat terjadi El Nino kuat. Sedangkan untuk La Nina juga tidak ada pergeseran musim, hanya terjadi peningkatan curah hujan. SST dan curah hujan berbanding terbalik, karena karakakteristik lokal yang kuat.

The geographical location of the University of Defense in Bogor Regency, Citereup Sub-district, Bogor, West Java, is a sloping terrain that can potentially cause landslides. The InaRISK map released by BNPB, shows that the Defense University is located in an area of Bogor Regency that is prone to disasters, especially landslides. Disaster risk assessment is an approach to show the potential negative impacts that may arise due to a potential disaster. The potential negative impacts are calculated based on the level of vulnerability and capacity of the area. This potential negative impact is seen from the potential number of people exposed, property loss, and environmental damage (PERKA BNPB, 2012). Researchers conducted an analysis of landslide and earthquake disaster vulnerability at the University of Defense. A study of building and population vulnerability to potential earthquakes and landslides was conducted at the University of Defense. The components of social vulnerability at the University of Defense in the event of an earthquake and landslide were obtained. Researchers obtained data on population capacity and building conditions at the University of Defense. Landslide and earthquake disaster risks have the potential to occur at the University of Defense. The University of Defense has the potential threat of landslides because the buildings of the University of Defense are located on hilly slopes. The vulnerability of the University of Defense buildings, the University of Defense buildings have not been designed to be entirely earthquake resistant. This can be seen in some buildings that have visible cracks. It is necessary to retrofit or strengthen the foundations of buildings in the Defense University area that have experienced a decrease in performance such as cracking, shifting, displacement. An important component where the University community and students need self-protection and rescue skills through training.

Areas with high population density have the potential to degrade environmental quality. This is because an increase in population leads to a higher amount of waste accumulation. Bogor City is known for its dense population. In 2018, the Galuga Bogor Landfill received 650 tons of waste per day. With the population growing each year, accompanied by an increase in waste generation, there is a need for effective and sustainable waste management efforts. However, several obstacles are often encountered in waste management, such as the lack of understanding among the population. If left unaddressed, this situation can have serious implications for the environment, leading to natural disasters and public health issues. The aim of this research is to predict the amount of waste accumulation in Bogor City, with the hope of assisting the government and the community in enhancing waste management practices. The research methodology involves the analysis of Causal Loop Diagram (CLD) and Stock Flow Diagram (SFD), which will be simulated using Time Graph and Time Table, and processed through the Powersim Studio 10 Express application. Simulation results indicate that waste accumulation in Bogor City is expected to continue increasing from 2018 to 2025. The difference in waste accumulation between 2018 and 2025 is estimated to be 87,783 tons, with the Bogor City Landfill projected to receive 890 tons of waste per day by 2025.
