Abstract

Palangka Raya, as the capital of Central Kalimantan Province, is facing an increasing demand for drinking water due to rapid population growth. PERUMDAM, as a regional government-owned company (BUMD) responsible for public services, plays a crucial role in providing safe drinking water to the community. To address this issue, the local government is planning to develop a piped drinking water supply system (SPAM) using water sources from the Tumbang Rungan intake. This study aims to analyze the financial feasibility of this development plan using indicators such as Net Present Value (NPV), Benefit Cost Ratio (BCR), Internal Rate Return (IRR), and Payback Period (PP), while also considering the affordability of the community through the Contingent Valuation Method (CVM). The evaluation results show that the willingness to pay (WTP) is IDR 11.872/m³ and the ability to pay (ATP) is IDR 7.084/m³, both of which are higher than the current tariff of IDR 4.780/m³. This indicates that the community is willing to accept a tariff increase for better services. The financial feasibility analysis shows that this project is viable and supports efforts to expand piped drinking water services in Palangka Raya.

Abstract

One of the government's efforts to improve drinking water services is the implementation of a community-based drinking water supply system (DWSS) through the Community-Based Drinking Water Supply (PAMSIMAS) program. This study analyzes the sustainability of PAMSIMAS to assess its sustainability status, identify influencing factors, and formulate management strategies to ensure the sustainability of the program. The method used for the sustainability analysis is Multidimensional Scaling with RAPFISH, focusing on technical, institutional, financial, social and environmental aspects. SWOT analysis is also used to determine management strategies. The study was conducted in seven PAMSIMAS sites in Setu District, Bekasi Regency, with data collected through questionnaires, interviews and observations. The results show that the seven CBWS fall into the "fairly sustainable" category, with sustainability index values ranging from 60.00 to 72.00. The main factors influencing sustainability are water quantity, sanctions, regularity of payments, community meetings, and protection of water sources. The SWOT analysis shows that six CBWS are in Quadrant I, requiring an aggressive system development strategy. Meanwhile, another PAMSIMAS site is in Quadrant III, requiring a turnaround strategy to minimize weaknesses and capitalize on opportunities.

Abstract

The benefits of binahong leaves (Anredera cordifolia) in the treatment of external wounds and as an anti-inflammatory agent can be optimised when used in topical form compared to the extract form. This research aims to determine the particle size characteristics and entrapment efficiency of the phytosome suspension of thick ethanol extract of binahong leaves using phosphatidylcholine via PSA and calculate the entrapment efficiency using the 1:1 formula. The research was carried out using a laboratory experimental method where the phytosome suspension was prepared by thin layer hydration. Phytosomes are a technology developed for the formulation of drugs and nutraceuticals containing hydrophilic active compounds from natural sources (such as herbs). This is achieved by complexing the active ingredients (phytoconstituents) with phospholipids. The resulting phytosomes typically have an average particle size of 50 nm to 500 µm, which is the result of complexation between the plant active ingredients and phosphatidylcholine. The phytosome suspension is prepared from a mixture of phytosome complex, ethanol and water, which has been subjected to thin layer hydration. The results of previous studies show that it is possible to prepare phytosome complex suspensions using natural materials and phosphatidylcholine carriers, with the resulting particle size characteristics and entrapment efficiency varying. The mean particle size of the phytosome suspension of the thick ethanol extract of Binahong leaves was 1.154 ± 0.745 µm with a polydispersity index of 0.416 and an entrapment efficiency value of 82.7140%.

Abstract

The aim of this research is to design and build a Software Defined Radio (SDR) based ground station for communication with low earth orbit (LEO) satellites at 437 MHz. This ground station is designed to overcome the challenges of high cost and hardware complexity in conventional satellite communications. Methods used include system development using two Yagi antennas as transmitters and receivers, and the use of Raspberry Pi and RTL-SDR for signal processing. Tests were conducted at Telkom University, Bandung, with results demonstrating the ground station's ability to effectively track and receive signals from multiple LEO satellites. The test results show that the system can operate well in the UHF frequency range, with stable signal reception despite some minor interference. The study concludes that the use of SDR can increase the flexibility and efficiency of satellite communications, and provides recommendations for further hardware and software improvements to improve satellite tracking accuracy.

Abstract

In 2010, Indonesia ranked fourth in terms of waste generation. As a result, the waste sector is estimated to potentially contribute 296 Mt CO2 eq (10.32%) of total greenhouse gas (GHG) emissions by 2030, with a projected annual growth rate of 6.3% using the business-as-usual (BAU) projection from 2010 to 2030. Around seventy per cent of all waste is organic, making household waste one of the main sources of urban waste. This study was conducted at the Benowo Landfill in the city of Surabaya. The SNI 19-3964-1994 method was used to sample the composition and generation of waste at the landfill. Waste generation projections were made up to 2030, taking into account population growth. This study compares methane gas emissions from three scenarios: Scenario 1, direct landfilling of waste; Scenario 2, waste reduction through composting and 3R processing; and Scenario 3, waste processing at the landfill through gasification. Based on inventory calculations using the 2006 IPCC guidelines, the landfill scenario produces the highest greenhouse gas emissions (CO2 and CH4), with the highest CH4 emissions and the lowest CO2 emissions. The gasification scenario has the highest CO2 emissions and the lowest CH4 emissions due to the use of aerobic systems and combustion.

Abstract

In 2022, the energy cost of PT. Air Minum Bandarmasih Kota Banjarmasin will be Rp. 586/m3 while the national average energy cost was Rp. 363.45/m3. In 2023, IPA 2 Pramuka distributed 41,152,457 m3 at an energy cost of Rp. 479.13/m3. A key step in energy management is to conduct regular energy audits. Energy audits are conducted to assess pump efficiency and determine Specific Energy Consumption (SEC), which facilitates technical recommendations for energy management. The first results of the energy audit at the IPA 2 Pramuka distribution unit of PT. Air Minum Bandarmasih revealed a power factor (cos φ) of less than 0.85, which is detrimental to energy efficiency. The pump efficiency was 50-60%, indicating that minor pump adjustments were needed. In addition, the SEC in 2023 was slightly above 0.4 kWh/m3 (about 0.40094 kWh/m3). The proposed improvement measures were the repair of the pump and regular maintenance, as well as the installation of a capacitor bank to improve the energy efficiency of the distribution unit of IPA 2 Pramuka.

Abstract

This study focuses on the pollution of the Gude Ploso River in Jombang Regency, East Java Province, Indonesia, mainly caused by household and tofu industry waste. To control pollution, it is crucial to identify pollution sources, predict changes in water quality, and test the effectiveness of mitigation strategies. Our results show that several parameters in the Gude Ploso River exceed permissible limits, including total suspended solids (TSS), phosphate, and chemical oxygen demand (COD). Pollutant carrying capacity calculations indicate that phosphate and COD levels exceed the maximum carrying capacity at all sampling sites. Analysis using the STORET method indicates moderate levels of pollution with values of -30, -20, -21, and -21. Proposed mitigation strategies include monthly or quarterly monitoring of factories near the Gude Ploso River, conducting outreach and workshops for local communities to raise awareness about the state of the river, implementing phytoremediation at various points along the river, establishing environmental NGOs in the area, and conducting water flushing during dry periods. These strategies aim to reduce pollution in the Gude Ploso River, ensure the sustainability of its ecosystem, and provide a decent quality of life for the communities that rely on the river as a water resource.

Abstract

Shipyards are often criticised for the liquid waste they produce, which has the potential to contaminate marine waters. This research aims to analyse the effectiveness of chitosan from blood clam shells as an adsorbent to reduce the levels of lead and copper in shipyard liquid waste. The research technique uses a batch system. The materials used include both commercial and non-commercial blood clam shell adsorbents. The non-commercial blood clam waste was collected from a fish auction site in Kalanganyar village, Sidoarjo. The concentrations of lead and copper in the wastewater samples were 2.04 and 1.16 mg/L, respectively. Variations in the adsorption stirring speed (90, 100, 110 and 120 rpm) and the amount of commercial and non-commercial blood clam shell adsorbent added to the wastewater samples (0.5; 1; 1.5; and 2 grams) were tested. Measurements were then performed using atomic absorption spectroscopy (AAS). At final concentrations of 0.150 mg/L and 0.144 mg/L, the research results show that the commercial adsorbent with a mass of 2.0 grams and a stirring speed of 110 rpm was able to absorb Pb and Cu metals at 92.65% and 87.58% respectively, while the non-commercial adsorbent with a mass of 2.0 grams and a stirring speed of 110 rpm was able to absorb Pb and Cu metals at 91.81% and 82.31% respectively.
