Amplapura is located in the highlands having a potential area of green open land which can absorb rainwater freely into the ground. However, in recent times, land conversion has begun to develop with new housing buildings, Griya Galiran Regency Housing. Furthermore, the effectiveness of the land area is still able to absorb water and maintain groundwater balance. A rainwater harvesting plan (RH) is needed, or, more popularly, rainwater harvesting. In this area. The aim is to provide a portion of residential land space for rainwater infiltration into the pores or soil cavities using the infiltration well method. The results showed that the Griya Galiran Regency Housing had an acceptable sand soil type and absorbed soil quickly, with a soil permeability coefficient (k) of 0.0014 cm/s. Designing the dimensions of the infiltration well at the Griya Galiran Regency Housing with an area of 70 m2 based on SNI 03-2453-2002 for a circular cross-section, an infiltration well with a diameter of 1.2 m with a depth of 2 m is made. In contrast, as a rectangular cross-section, an infiltration well has a side length of 1 m with a depth of 2 m.

PT. X is one of the ice companies in which its largest company is located in Bali, more precisely in the Pidada area, North Denpasar. Based on field observations the area is an area that has a calcareous soil structure. The water source of PT. X was extracted from the groundwater. From the field observation, it was found that the pipeline network, that connected the inlet water to water treatment system and ice production units, was severely covered by faint white scale. In order to discover the origin of this scale, water quality testing need to be carried out. From the results, it was found that the total hardness in the inlet water, taken from the groundwater tap, was 162.85 mg/l with calcium concentration of 2.15 mg/l and iron 3.83 mg/l. Water quality testing was also carried out in the water treatment unit consisting of resin softener where the total hardness surprisingly increased into 279.81 mg/l, calcium concentration was 2.96 mg/l, iron concentration was 0.55 mg/l. Even after being treated in softener resin, the total hardness increased sharply to 483 mg/l, which categorized as extreme hardness. The increase in total hardness indicates that there was a failure in the operation of the water treatment system, even it also contributed to the higher hardness and calcium concentration. This over-year’s treatment failure has been causing accumulation of hardness and calcium concentration in the compartment of both water treatment system and ice production unit that inflicts a higher hardness level in the effluent.

The increase in mask waste and a lack of understanding about the management of single-use mask waste raises the potential for environmental pollution and COVID-19 transmission. Aim: This study aimed to assess the level of understanding of medical mask waste management and strengthening health protocols in controlling COVID-19 infection in Banjar Purwa Santhi, Benoa, Badung Regency. Methodology and Results: A cross-sectional method and descriptive study design were used with a sample of 100 respondents selected via stratified sampling. The research and service activities at Banjar Purwa Santhi Benoa include public campaign and assessment of the level understanding of medical mask waste management. Based on univariate analysis, 91% of respondents know that mask waste contains hazardous and toxic substances. If mask waste is disposed carelessly, 98% of respondents stated that it can pollute the environment, and 98% of respondents also stated that it has the potential to become a means of transmitting COVID-19. However, 85% of respondents disposed of the masks in the household trash. Conclusion, significance and impact study: Respondents had a good level of knowledge about health protocols and mask waste management but have not separated masks from household waste. By holding the community service activity, it is hoped that changes in community behavior will occur.

The Tukad Badung River is a vital raw water source in Denpasar City and Badung Regency. Concerning the water pollution of the river, water treatment is necessary to manage the water quality. Constructed wetlands are a water treatment technology used for water purification. In this regard, information is essential regarding the appropriate location for the placement of the constructed wetland based on criteria related to the water treatment plant. The research was conducted to determine the suitability level of water treatment locations in the watershed using the Analytic Hierarchy Process method in integration with a Geographic Information System. The Geographic Information System analysis included overlaying steps of the processed and classified data from each criterion: land use, slope, and water pollution index. The Analytic Hierarchy Process method was carried out to obtain the weight of each criterion down to the sub-criteria, which were compiled through interviews with three informants from academic, government, and community representatives. Weight calculations were performed using Expert Choice 11 software to obtain weight values with a consistency ratio of < 0.1. Geographic Information System analysis using the Analytic Hierarchy Process method produces three suitable land types according to the level of suitability for water treatment locations, with constructed wetlands located in the upstream, middle, and downstream parts of the river. Information regarding suitable land is useful for planning the technical design of water treatment plants with constructed wetlands.

Kelompok Sadar Wisata (Pokdarwis) Dwi Manunggal di Desa Manistutu, Kabupaten Jembrana, menghadapi tantangan dalam Integrasi sistem pengolahan limbah organik berbasis budidaya Black Soldier Fly guna menunjang praktik agrowisata ramah lingkungan dan berkelanjutan. Tujuan utama adalah meningkatkan kunjungan wisata dengan mengembangkan daya tarik edukatif agrowisata yang selaras dengan tren wisata terkini. Kendala dalam pengemasan dan pemasaran daya tarik wisata, seperti ketidaksesuaian dengan tren industri pariwisata, menyebabkan daya tarik wisata terlihat usang. Melalui pelatihan dan pendampingan, Pokdarwis diberdayakan untuk menggunakan teknologi digital, seperti website dan media sosial, guna meningkatkan kualitas dan daya saing produk wisata. Pelatihan ini diharapkan dapat memperbaiki pengemasan produk hasil budidaya BSF, seperti kompos dan pakan ternak, yang dikemas dengan label informatif mengenai manfaat pengelolaan limbah organik. Strategi digital marketing dengan memanfaatkan media sosial menjadi solusi dalam memperluas jangkauan pemasaran. Konten menarik, seperti foto, video proses budidaya, dan informasi manfaat BSF, diunggah untuk menarik perhatian calon wisatawan. Solusi ini diharapkan tidak hanya meningkatkan kualitas produk dan efektivitas pemasaran, tetapi juga memperluas kesadaran publik akan pentingnya pengelolaan limbah organik. Melalui pendekatan ini, Pokdarwis Dwi Manunggal diharapkan mampu mendukung pengembangan agrowisata berkelanjutan di Desa Manistutu, meningkatkan daya saing, dan meminimalisir limbah organik di kawasan tersebut.
