Abstract

Converting conventional motors into electric vehicles can reduce dependence on fossil fuels. The conversion process involves engine replacement, charging system installation, and vehicle structure modification. The conversion program was carried out involving workshops and vocational high school students. The Social Return on Investment (SROI) method was employed to measure the social and economic impacts of the program, involving impact identification, measurement, monetization, cost comparison, and analysis. The PLN Cares program undertook motor conversion with the aim of improving sustainability and quality. The research problem and objectives focused on measuring the SROI in the electric motor conversion program. The research method employed a qualitative approach with data collection techniques through in-depth interviews, focus group discussions, observations, and literature studies. Data were continuously analyzed during and after collection. SROI calculations involved initial investment capital input and impact value, resulting in an SROI ratio of 5.03. The research results indicated that the PLN Cares program had a significant social impact, with an SROI ratio indicating a profitable investment value. Conclusions and recommendations involved maintaining the working mechanisms, synergy among stakeholders, and using the program as a guide for similar projects in the future.

Abstract

This research aims to model residual chlorine in the drinking water distribution system with EPANET 2.2 software in the IPA Aurduri 3 of service area. The problem that occurs is the construction of the Aurduri 3 IPA in 2020 to meet the need for clean water in several areas that are not reached by the Aurduri 1 IPA and 2, especially the Bougenville, Pinang Merah and surrounding areas. Adding chlorine twice, namely at the IPA Aurduri 3 and the booster pump, increases the risk of excess chlorine in the service area and can reduce water quality. Modeling the distribution of residual chlorine in the clean water distribution system can provide a solution in dealing with residual chlorine in drinking water distribution. The results found of 30 points in the clean water network that were below standard and dominated at the service end with residual chlorine ranging between 0-0.4 and after calibration 0.16-0.3. This is due to the age of the water which is influenced by velocity which does not meet the standard by 121 points and causes delays in obtaining residual chlorine at sufficient levels.

Abstract

This study aims to determine the effect of combining Kasgot fertilizer with dolomite on the growth and production of mustard plants, identify the best dose of Kasgot for mustard plant growth and production, and assess its impact on the properties of Ultisol soil. The study used a factorial Completely Randomized Design (CRD) with combinations of Kasgot fertilizer and dolomite, resulting in 10 treatments and 3 replications, yielding a total of 30 experimental units. M0 = NPK fertilizer at 200 kg/ha, M1 = 50 t/ha, M2 = 60 t/ha, M3 = 70 t/ha, M4 = 80 t/ha, D0 = without dolomite, D1 = with dolomite (1.4 t/ha). The results showed that applying dolomite at a dose of 1.4 t/ha (D1) significantly affected the growth of mustard plants compared to the treatment without dolomite (D0). The use of Kasgot fertilizer at a dose of 80 t/ha (M4) provided the best results for mustard plant growth, and the application of Kasgot fertilizer with dolomite was proven to improve the chemical properties of Ultisol soil, leading to increased pH, P-potential, and K-potential values.

Abstract

There is a gap between existing climate information and the needs of annual dam operational planning. This study aims to demonstrate that the percentile approach currently used for planning is not optimal, especially now that automation has become more accessible. The purpose of this study is to design an automated forecasting and evaluation system based on 36 10-days rainfall projections using a multi-model approach. This approach comprises a percentile, ARIMA, ECMWF+ARIMA, IOD DMI regression, ERSST regression, and ensemble methods models. Additionally, this study aims to demonstrate how a verified, multi-model-based rainfall forecast can provide more reliable assurance for the annual operational planning of Lahor-SutamiDam, simulated operationally in November 2022 for the 2022/2023 planning cycle. Data utilized include historical 10-days rainfall data from 1991 to 2023, ECMWF raw and corrected model outputs, Nino-Dipole index, and global sea surface temperature. The verification method employs four criteria based on MAE and fit index. An operational simulation approach is used for training-testing period segmentation, while a 10-year window is applied to account for possible climate-change-induced shifts in relationships. Single linear regression is used to avoid overfitting. The automation system was developed using R-Statistics. Results indicate that the current approach is only optimal for 58% of locations. Superior methods identified include ECMWFcorrected, ERSST regression, and Ensemble models. A case study for 2022/2023 demonstrates that the forecast results outperform the existing plan for at least 78% of the projected periods.

Abstract

Water hyacinth (Eichhornia crassipes) and Purun tikus (Eleocharis dulcis) plants are commonly found in rice fields, especially in South Kalimantan, where they act as weeds in the main crop. However, these plants can be utilized as compost to enhance soil nutrients for crops. This study aims to evaluate the effect of compost derived from water hyacinth, Purun tikus, and their combination on the growth and yield of purple eggplant (Solanum melongena). The study uses a Randomized Block Design (RBD) method with four treatments, each repeated six times, resulting in 24 experimental plants as follows: P0 = no treatment (control), P1 = 900 g water hyacinth compost, P2 = 900 g Purun tikus compost, and P3 = a combination of 450 g water hyacinth compost and 450 g Purun tikus compost. The results indicated that, for plant height, treatment P3 yielded an average of 53.61 cm; for leaf count, treatment P3 produced an average of 45.66 leaves; for stem diameter, treatment P1 achieved an average of 9.90 mm; for fruit count, treatment P3 showed an average of 2.16 fruits; and for fresh fruit weight, the best result was achieved by treatment P3, with an average weight of 145.83 g

Abstract

Sungkai leaf (P. canescens Jack.) is a native plant of Indonesia that has long been used in traditional medicine as a mouthwash and minor wounds. Sungkai leaves P. canescens Jack. are believed by the community to have many health benefits. Several studies have shown that sungkai leaves (P. canescens Jack.) contain active compounds. As for the extraction process, it is known that the content of active compounds obtained in the sungkai leaf extract is strongly influenced by the selection of solvents used and the extraction method carried out. In previous studies, total flavonoid content has been obtained using maceration and soxhletation methods in sungkai leaf extracts, where flavonoids are one of the profiles of secondary metabolite compounds possessed by sungkai leaves. In the next research, the profile of sungkai leaves will be determined more thoroughly through phytochemical screening and GCMS analysis of the extraction results using maceration and soxhletation methods. The histochemical profile of sungkai leaves will also be determined. Histochemical test results show that flavonoid compounds are evenly distributed in all tissues of sungkai leaves, besides that some tissues in sungkai leaves show positive results for the presence of alkaloid, steroid, terpenoid, tannin, phenol and saponin compounds.The results of phytochemical screening showed that sungkai leaves positively contained secondary metabolite compounds in the form of alkaloids, flavanoids, steroids, terpenoids, tannins, phenolics, saponins while the results of GCMS analysis for the maceration process obtained metabolite compounds in the form of terpenoids, alkaloids, and phenolics, while for the sokletation process obtained metabolite compounds in the form of flavonoids, terpenoids, and phenolics.

Abstract

An area of 1,853 ha (65.2%) of land in Megaluh District is used for rice fields. Pesticides and inorganic fertilizers are widely used as plant fertilizers in Megaluh District, where excessive use in rice fields can pollute the groundwater below. This research is aimed at identifying spatially the possibility of groundwater pollution using the hydrogeological approach of the SINTACS method. The SINTACS method has five scenarios that produce different weights for each parameter that can cause groundwater vulnerability. The data used in the SINTACS method are groundwater depth, infiltration rate, unsaturated zone, soil texture, aquifer media, hydraulic conductivity and topography. This research uses variations in the depth of the groundwater level to determine the trend in the level of groundwater vulnerability in Megaluh District during the rainy season and dry season with a severe impact scenario as an approach to environmental conditions in Megaluh District. The results of the analysis show that the level of groundwater vulnerability in Megaluh District is in the range of 143.6 (rather high) – 198 (high). The percentage of rice field area which reached 65.2% resulted in a rather high level of vulnerability of 42.35% and a high level of vulnerability of 57.65%.

Abstract

Laboratory wastewater is characterized by significant pollutants, including surfactants, phosphates, organic compounds, and inorganic compounds, leading to elevated BOD levels. BOD (Biological Oxygen Demand) serves as a key parameter for assessing the likelihood of pollution in waste materials. The higher the BOD level, the greater the potential for pollution. The utilization of phytoremediation technology with water hyacinth plants presents a promising alternative for the removal of waste pollutants, harnessing natural resources that are frequently regarded as weeds. This study thus seeks to examine BOD levels, the impact of water hyacinth quantity and waste exposure duration, and the effectiveness of the water hyacinth phytoremediation technique in lowering BOD levels in laboratory waste. This study’s benefits are to provide information on BOD level analysis, examine the impact of water hyacinth quantity and the duration of waste exposure, and assess the effectiveness of the water hyacinth phytoremediation method on BOD levels in laboratory waste. The employed research method is experimental, utilizing phytoremediation with water hyacinth plants, structured as a Factorial Randomized Block Design (RAK) with two factors and three replications. The variations consisted of 5, 10, and 15 plant clumps, with exposure durations of 3, 6, and 9 days. BOD levels were determined using the SNI 6989.72: 2009 method for the Biochemical Oxygen Demand/BOD test. The study results demonstrated an efficiency in reducing BOD levels ranging from 83.60% to 96.33%. The number of water hyacinth clumps and the duration of waste exposure had a substantial impact on the reduction of BOD and COD, with a significance level of less than 0.01. The effectiveness of the water hyacinth phytoremediation method in reducing BOD levels in laboratory waste achieved a notable N gain score of 93.27%. In conclusion, the efficiency of BOD reduction attained 96.33%. Furthermore, an increased quantity of water hyacinth plants and prolonged exposure to waste would further diminish BOD levels, indicating that the water hyacinth phytoremediation technique is effective in lowering BOD levels in laboratory waste.

Abstract

The Gembong River is a river included in the longest watershed in Pasuruan City with a length of 7.5 km. The estuary of the Gembong River is relatively wide, so it is used as a traditional port. However, the river flow in Pasuruan does not meet the quality standards for class two due to the large number of pollutants from the household and industrial sectors. Based on the results of observations that have been carried out in the Gembong River estuary area or the Pasuruan City port area, it can be seen that there is still some waste, ranging from household waste and plastic waste from snack wrappers. The method used in this study was descriptive qualitative. Data were collected through observation and interviews with 36 respondents. The instruments used in collecting data were questionnaires and interview guidelines. The sampling technique used was purposive sampling. Primary data in the form of analysis of data results regarding aspects of knowledge, attitudes, and actions of the community towards efforts to maintain river sustainability. Secondary data in the form of water quality index and its parameters in the Gembong River estuary area. The results of this study showed that based on the results of the water quality test analysis, it can be seen that the Gembong River is included in the river with lightly polluted criteria. awareness and behavior of the community around the estuary of the Gembong River or the port of Pasuruan City is quite good. However, there is still a need for optimization of the government's work programs in conducting socialization and involving the community in the prevention or control program for river pollution, so that it is hoped that the community can actively participate in protecting the environment.

Abstract

This study aims to identify mangrove species and map the density of mangrove vegetation in the Tanjung Pemancingan area, Kotabaru, using an object-based classification method (OBIA) applied to Sentinel-2 imagery and Unmanned Aerial Vehicle (UAV) data. Mangroves play a crucial role in protecting coastlines from erosion and serving as habitats for various species, making an in-depth understanding of mangrove distribution and types essential for coastal conservation and environmental management. The OBIA method allows for more accurate mapping by considering texture, shape, and more complex spatial patterns compared to traditional pixel-based methods. This study employs the Support Vector Machine (SVM) algorithm in the classification process to enhance the accuracy of mangrove species identification. The analysis utilizes Sentinel-2 satellite imagery with a spatial resolution of 10x10 meters and UAV data for higher resolution. The results show that the NDVI values for mangroves in the study area range from -0.30 to 0.686, which were classified into three canopy density classes: sparse (-0.30 to 0.026), moderate (0.027 to 0.356), and dense (0.357 to 0.686). The OBIA method combined with the SVM algorithm successfully discriminated between seven mangrove species with an overall accuracy (OA) of 72.46%. The identified mangrove species include Avicennia alba, Avicennia marina, Avicennia officinalis, Avicennia rumphiana, Bruguiera gymnorhiza, Rhizophora apiculata, and Sonneratia alba, with Avicennia rumphiana being the most dominant species, covering an area of 13.87 hectares. The mangrove vegetation density was successfully mapped, providing valuable information that can be used in conservation planning, coastal resource management, and ecotourism development in the area. Furthermore, these results have significant implications for further research in mangrove ecosystem monitoring and the application of remote sensing technology in environmental management.
