Abstract

Jalan Sungai Ampal in front of the fresh market of Balikpapan Baru often inundation occurs when it rains. This is due to several factors, one of which is rainwater passing through the drainage channel that exceeds the storage capacity so that the water overflows which causes puddles in the surrounding area. In order for the handling to be carried out effectively, a thorough analysis of the drainage system is needed which will then be used as the basis for determining the handling of inundation. Data analysis in this research uses SWMM 5.1 application. Starting from knowing the cause of inundation to planning the ideal drainage channel capacity. This analysis is also assisted by the google earth application to see thearea subcatchmen, slope and soil elevation at the research site. Simulation of the ideal planned drainage channel capacity is carried out using the trial error method on the SWMM 5.1 application. From this method, the ideal design channel capacity is 1 m. On channel 1 can accommodate 0.574 m3/ sec with a maximum flow of 1.58 m / s and the channel capacity by 60%. On channel 2 can accommodate 0.792 m3/ sec with a maximum flow of 1.15 m / s and the channel capacity by 82%. On channel 3 can accommodate 1.418 m3/ sec with a maximum flow of 2.27 m / s and the channel capacity by 74%. No problem channels were found after re-simulation using the design channel dimensions, so the design diameter of 1 m is considered safe.

Abstract

The shrimp nursery infrastructure consists of nursery tanks, mechanical filters, biological filters, and ultraviolet (UV) filters. This study aimed to simulate the water level elevation (head) of shrimp nursery infrastructure, especially nursery tanks. The placement of the nursery greatly affects the elevation of the water table owing to the loss of energy (headloss) that occurs in the flow. The nursery tub used in this study was round and consisted of four tubs made of fiber resin measuring 250 cm in diameter and 120 cm in height. The bottom of the tub was placed at an elevation of +40 cm above the ground. The simulation was conducted for 24 hours. The results of the EPANET 2.2 simulation showed head fluctuations in each nursery with the highest elevation (1.38 m and the lowest (1.20 m, from the data. The head fluctuated constantly after 6 h of the flow. The optimal pipe diameters were 3" (80 mm) PVC and 4" (110 mm) PVC.

Abstract

Water conservation efforts are needed to meet increasing water demand (e.g., rainwater harvesting) to help maintain water and environmental sustainability in the present and future. The interdependence of the five components, which comprised 31 factors, was examined in a quick assessment of urban rainwater harvesting. This study aimed to evaluate the sustainability aspect that affects rainwater harvesting based on five sustainability factors. Stages of the research methodology; 1) Preparation of the research area and respondents, 2) Collecting data through survey methods using interview techniques to obtain related data, 3) Conducting data analysis and characterizing the sustainability of rainwater harvesting, using multi-aspect analysis based on developed factors and attributes, and 4) Using two scenarios reasonably sustainable circumstances urban rainwater harvesting variables, adapting management strategies should be developed based on the urban rainwater harvesting sustainability research, which is in a reasonably sustainable environment. The results show that the sustainability status of urban rainwater harvesting in the City of Balikpapan is relatively consistent, with an indicator of 44.77%. Institutional and technological infrastructure are aspects of low sustainability. To raise sustainability status to 'sustainable,’ then choose scenario number 1, that is a realistic scenario in which the 10 sensitive factors are upgraded, thereby raising the sustainability indicator to 65.52%. The most sensitive attributes to be improved are poor groundwater quality, availability of funding for rainwater harvesting, need for roof cleaning, need for collaboration between stakeholders, and reduction of conflict over taking water sources.

Abstract

Ketersediaan air bersih di lembaga pendidikan dasar kerap terkendala kualitas air tanah yang mengandung besi (Fe) dan mangan (Mn) melebihi baku mutu. Kegiatan Pengabdian kepada Masyarakat (PKM) ini bertujuan meningkatkan kualitas air di TKIT–SDIT Bintang Bangsa Balikpapan melalui penerapan teknologi tepat guna (TTG) aerasi–filtrasi yang hemat biaya dan mudah dirawat. Kegiatan meliputi survei kualitas air, perancangan–fabrikasi sistem, instalasi–uji fungsi, pelatihan operasi–perawatan, serta monitoring–evaluasi. Sistem yang dibangun berkapasitas ±800 L/jam (≈6.000 L/hari), terdiri dari head aerator pipa perforasi, tray aerator tiga tingkat, dan tabung filtrasi berlapis (kerikil, pasir silika, mangan zeolit, karbon aktif), digerakkan pompa 90 W dan diintegrasikan ke tandon serta jaringan distribusi sekolah. Uji lapangan pada 18 Oktober 2025 menunjukkan penurunan kadar Fe sebesar ±80% (1,5 mg/L menjadi <0,3 mg/L), Mn sebesar ±85–90% (1,0 mg/L menjadi ±0,1 mg/L), kenaikan pH dari 6,0 menjadi 7,0, serta penurunan kekeruhan hingga <5 NTU; seluruh parameter memenuhi Permenkes No. 32/2017. Dampak sosial mencakup peningkatan partisipasi dan kapasitas warga sekolah (pelatihan, backwash rutin, pencatatan monitoring), sehingga sistem beroperasi mandiri dan berkelanjutan. Kegiatan ini berkontribusi pada pencapaian SDG 6, serta mendukung SDG 3, SDG 4, dan SDG 17 melalui kolaborasi perguruan tinggi–sekolah. Model desain dan pendampingan yang dihasilkan berpotensi direplikasi pada sekolah/pesantren dengan karakteristik serupa.
