Published: December 2023

AbstractWater demand always increases, and its availability varies between regions and times. Pekalongan City is a city that faces water scarcity issues. This study aims to determine the critical water distribution zones in the coastal area of Pekalongan City by considering the critical water criteria based on the use of meteorological water balance during the wet and dry months. The research location includes eight sub-districts in the coastal area of Pekalongan City, specifically in North Pekalongan District. Water criticality is calculated by considering water availability and water demand. Water availability is influenced by rainfall, evapotranspiration, runoff, and infiltration. Water demand for domestic, industrial, and agricultural sectors is calculated based on their respective classification standards. Surplus and deficit values are obtained using the water balance. Water criticality is classified into four categories by comparing the total water availability with demand. All sub-districts experience a water deficit during the dry months, while during the wet months, all sub-districts except Padukuhan Kraton and Panjang Wetan sub-districts experience a surplus. All sub-districts are classified as highly critical in the dry month period. During the DJF period, all sub-districts are classified as not critical and near critical, while during the MAM period, one sub-district is classified as not critical.

Abstract
Jakarta’s land continues to sink, and rising sea levels pose a high risk of tidal flooding in Jakarta Bay. From 2022 until May 2023, three tidal floods in Jakarta have been recorded due to high-intensity rainfall, causing the sea level to rise above normal. This threat is of public concern due to its material and immaterial losses. To address this issue, a real-time monitoring system that can provide accurate information on sea level heights on the coast of Jakarta needs to be developed. The research aims to develop a web-based Automatic Water Level Recorder (AWLR) system tool to support flood disaster mitigation in Jakarta’s coastal areas. This system integrates several sensors to measure sea level heights, temperature, humidity, and data transmission through a telemetry system. Based on running tests conducted from December 2022 to February 2023, the AWLR recording had been validated with BMKG’s Tide Gauge data installed in the same waters. The results show the data recording performance with high accuracy (98%). The successful performance of the sensors in this device is supported by monitoring devices involving temperature and humidity sensors. The initial calibration stage also shows significant accuracy test results with an error range of 2 -5%. The measurement accuracy of the pressure, temperature, and humidity sensors are 98%, 97%, and 95%, respectively, so the data obtained is reliable. This IoT-based AWLR data recording can be an input for coastal management decision-making, especially for monitoring coastal disasters.

Abstract
The area of Delta Mahakam has not been accessible by an electricity network for a long time and has been relying on gasoline as a source of electric power generation for daily and economic activity. The community uses the Solar Home System (SHS) unit for their home and public facility. The provision of these SHSs units was an activity of a community development program from a company having industrial activity in the area. This research aims to identify the SHS unit’s condition and the attributes relevant to the condition of the SHS unit. An SHS condition was determined by gathering data on the technical specification such as unit power size and battery capacity, electricity utilization, and its financing model. Data is collected using field survey, data collection, and interviews with respondents. The data was then analysed by the Recursive Elimination of Feature (Relief) method to select features sensitive to the condition of the SHS unit. The result of this study showed that the majority of SHS units are still functional to satisfy the electricity need. The set of attributes used in this research were accurate for the intended classes of SHS condition. This result provides information beneficial to improve the existing program and impact the community.

Published: December 2023

AbstractThis study aims to determine the response of growth and yield of taro plant genotypes to the level of soil water availability. The experiment was carried out using a divided plot design with the main plot being the rate of water application, namely: 60% FC (Field capacity), 80% FC, 100% FC, 120% FC and 140% FC, while the subplots were taro genotypes consisting of two types of dasheen (Ketan and California genotype), two types of eddoe (Satoimo and Jepang Hijau) also Xanthosoma (Talas Kuning). Parameters of plant growth observations included plant height, number of leaves, leaf area, stem diameter and width of canopy, while parameters of harvest observations included tuber fresh weight and total fresh weight. Physiological observations include chlorophyll content and number of stomata. Plant height of all types of taro was more vigor at 120 and 140% FC of water. For dasheen type taro, California taro with 140% FC treatment produced tuber fresh weight 36% higher than California taro plants at 60% FC treatment, while for Eddoetypetaro, Satoimo taro with 140% FC treatment produced tuber fresh weight 25% higher thanin 60% FC treatment. This proves that 5 genotypes of taro adaptive on waterlogging stress rather than drought stress. Satoimo and Jepang Hijau (eddoe type) are more adaptive to drought and wet soil conditions than talas Ketan, California and Talas Kuning (dasheen type).

Abstract
Our lack of fundamental knowledge about species occurrence, abundance, distribution, threats, and habitat requirements makes it challenging to conserve biodiversity in the face of rising human pressure. To obtain this information, practical and sensitive methods are required to identify and quantify the occurrence and diversity of rare, cryptic, and elusive species. Environmental DNA (eDNA) is a new technology that can help to discover and quantify biodiversity by addressing some of the limitations of conventional surveys. This study aimed to evaluate the biodiversity and composition of benthic species in the Lower Ciliwung River, Jakarta, Indonesia. The investigation was conducted from upstream to downstream of the river at the three sites during the dry season (July 2022). The DNA read sequences were used to examine the composition, relative abundance, and diversity of the samples. In this study, 1,492,975 initial reads were filtered down to 1,265,307 reads belonging to 27 species of benthic organisms. The taxa identified from the eDNA samples revealed that the most frequently detected species belonged to the family Siboglinidae, order Sabellida, and class Polychaeta. The composition of benthic species discovered in the eDNA water samples varied substantially (p ≤ 0.05). Osedax sp. (class Polychaeta) was the most prevalent species across all locations. The diversity index (H) ranged from low to moderate. eDNA offers potential advantages, but is hampered by DNA degradation, primer sensitivity, and the inability to distinguish between dead and living organisms.

Abstract
Utilization of ex-tin mining land as agricultural land is thought to have the potential to contribute heavy metals in agricultural products. The research objective was to obtain data on the metal content of Pb, Cd, and Sn in various vegetable crops such as spinach, cucumber, tomato, cayenne pepper, bitter guard, eggplant, pumpkin, and pepper. In addition to obtaining data on bioconcentration factors (BCFs) of metals in various vegetables. Vegetables were obtained from ex-mining vegetable fields in Jelitik Village, Gunung Pelawan, and Rebo Village, and metal measurements used Analytical Flame Atomic Absorption Spectrophotometry (F-AAS) Jena ContrAA 300. The results showed that the Sn metal in all vegetables analyzed ranged from 4.71 -10.86 mg/kg, Pb ranged from 0 – 5.0 mg/kg, and Cd metal was not found in all the vegetables and soil samples analyzed. The highest of Sn was found in spinach, and Pb in pepper. Generally, the Pb, Cd, and Sn content in vegetables still meets the Indonesian National Standard (SNI) No. 7387:2009, because not exceed the recommended quality standards. Soil from the three villages of ex-tin mining is not categorized as polluted with Pb, Cd, and Sn metals because it does not exceed the target values recommended by WHO. The TFs (Transfer Factors) value of metals in all types of vegetables analyzed was < 1, meaning that the ex-tin mining lands in Jelilik Village, Gunung Pelawan, and Rebo Village, Bangka are still relatively safe for growing vegetables because they do not contribute to the pollution of Pb, Cd, Sn.

Abstract
Seed exploration is one of the conservation strategies used to enhance the collection of seeds as natural resources in the seed bank. In 2020, we explored Nusakambangan Island from the West Nusakambangan nature reserve area, Batar Panjang coast, to Kali Jati Riverbanks. The exploratory approach and direct fruit tree sampling were employed. This study seeks to collect and preserve plant seeds and discover their biological seed characteristics. Thirty-two (32) collection numbers were obtained, consisting of 22 families and 27 genera. Moraceae and Euphorbiaceae (4 species) have the most fruiting trees in this exploration. Ficus variegata, Mucuna gigantea, and Ziziphus horsfieldii are new Bogor Botanic Gardens database collections. Most seeds (75%) we collect are orthodox and suitable for long-term storage. In addition, the specimens are not endemic or endangered trees; few still need identification. Also, this study provides information on biological seed characteristics that facilitate seed conservation storage at Bogor Botanical Garden Seed Bank.

Published: December 2023

Abstract
Kundur Island has incredible potential for tropical fruits in Riau Islands Province. Land utilization for tropical fruit planting must be supported by land resource data, such as maps of characteristics and land suitability, to optimize tropical fruit production. This study aimed to evaluate the land suitability and determine the dominant limiting factors for tropical fruit growth and development. Land suitability was evaluated by matching the land characteristics, soil, and climatic requirements for durian, rambutan, and duku. The land suitability classes for durian, rambutan, and duku on Kundur Island are mostly marginal (S3), covering an area of 28,361 ha (90.51%), while the rest are moderately suitable (S2) and unsuitable (N). The limiting factors are drainage, root conditions influenced by peat thickness, nutrient retention, nutrient availability, depth of sulfide material, and erosion hazards. Improvements can be made by managing drainage, using cover crops, fertilization, and providing soil ameliorants. Treatments to increase land suitability must be implemented to enhance the potential of durian, rambutan, and duku plantations to be suitable (S1) or moderately suitable (S2). Land potential development for durian, rambutan, and duku is conducted by prioritizing environmental aspects and land sustainability.
Current uses of topology in 3D GIS: An overview
Authors: Salleh Syahiirah , Ujang Uznir 
Published: December 2023

Abstract
3D GIS has been widely used in various applications that require 3D visualisation and analysis. This has also been made possible by advances in data acquisition, which provide detailed and accurate spatial data as the basis for any task. Topology as a spatial property gives value to 3D GIS by maintaining connectivity, adjacency, and containment information. This study attempted to understand how topology is used in 3D GIS based on a literature review. SCOPUS databases were searched for journal articles, conference proceedings, and book chapters that implemented topology as part of their 3D GIS methodology. Keywords used to search for literature were “topology” and “3D GIS”. The articles were selected based on the uses of topology in 3D GIS. The term ‘uses’ indicates topology being used in the methodology of a 3D GIS study to achieve the objective. Based on the review, we were able to categorise the literature into 3 main uses of topology, which are validation, data reconstruction, and spatial analysis or queries. The results of the literature review were also visualised using a network map of terms that also represents the connectivity and weightage between terms. This overview provided an awareness of future research areas in which topology assisted data validation, data reconstruction, and spatial analysis can be applied and fully utilised to further enhance 3D GIS capabilities.
Integration of interferometry and altimetry techniques for comping and reducing the desertification phenomena in Iraq
Authors: Aryan Murtadha , Bin Rasib Abd Wahid 
Published: December 2023

Abstract
Iraqi society has always suffered from desertification which has started to spread suspiciously and whose worsening has been brought on by inadequate water resource management. It is essential to mention, that the desert dominates large areas of the western part of Iraq, and the southern part of this desert is very influential on the climate. Therefore, the study area is located in the southwestern part of the desert of Iraq (29°02’17.91 N; 46°25’43.54 E) and covers 65,000 square kilometers. This study investigates novel integrated altimetry and interferometry techniques based on Sentinel satellite data for water resource management and marshland generation. Altimetry satellite data from Sentenel-3A and B was used to determine the Euphrates River’s water surface elevations and contribute to determining the location for the branching of the new river, which supplies the marsh area with water. Furthermore, the determination of the channel path and the location of the marshes depends entirely on the elevations extracted from the digital elevation model (DEM) that was generated by the interferometric synthetic aperture radar (InSAR) technique by using two Sentinel-1 images for the study area. The study’s findings include a topographical map with contour lines produced by a digital elevation model (DEM) with an RMSE value of 0.36 m. Moreover, despite the Euphrates River’s small width, the altimetry outputs and gauge station data exhibit high agreement. The Sentinel-3 satellites showed the following absolute/relative RMSE results: 0.35 m/0.39 m (Sentinel-3A), and 0.29 m/0.37 m (Sentinel-3B). The results demonstrate how integrating altimetry and interferometric methods helps manage and monitor Iraq’s water supplies.

Published: December 2023

Abstract
As a result of the colonial administration’s use of correspondence, agreements, and gazettes to define interstate borders along the borders of neighbouring states, peninsular Malaysia’s interstate borders were organically drawn around rivers and watersheds. Unfortunately, several flaws need to be fixed, including the river’s fluctuating path, delays in decision-making, and the state government’s ignorance of the significance of demarcation. Due to the significant social, economic, political, and jurisdictional ramifications, the demarcation of the interstate border in peninsular Malaysia has been the focus of intense controversy. The interstate natural boundary, like the river, is linked to damaging common-pool resources in addition to the overconsumption of natural resources. In order to give a thorough understanding of inter-state border demarcation and to implicate useful policy actions, the application of effective factors for inter-state border demarcation revision into six factors should be made based on its impact: constitutive agreement, authoritative mandate, operational structure, technical specifications, dispute resolution mechanisms, and additional components known as sustainable border governance. This review was carried out by carefully examining the supporting data from the extensive border studies literature and questionnaire. The idea of interstate boundary demarcation involves several aspects that show how changing state borders can affect both states’ authority, law enforcement, socioeconomic conditions, and tax revenues. In order to help readers better comprehend the significance and impact of interstate border delineation in peninsular Malaysia, this article offered a different perspective on the topic.
