Abstract

The expansion of agricultural commodities including oil palm plantations potentially causes an increase of greenhouse gas emissions by amplifying carbon dioxide (CO2) in the atmosphere. In the long term, this amplification will alter climate change. However, oil palm also has the potency to reduce greenhouse gas emissions by absorbing CO2 through photosynthesis. This study aims to determine the carbon stock that can be absorbed by oil palm and rubber plants, and to determine the relationship of rainfall with carbon stock in oil palm plants. The study used satellite image data based on Landsat and combined with rainfall data from near Perbaungan District, North Sumatra. Three Landsat data (acquisition date: (i) 12 February 2000, (ii) 8 March 2009, and (iii) 11 August 2019) were processed to estimate carbon stock. The procedure for estimating carbon stock was as follows: determining the sample and digitizing the sampling points, converting the digital value of the numbers into the spectral spectrum, calculating the albedo values, calculating the long-wave and short-wave radiations, computing biomass, and the absorbed carbon stock. The results showed that the carbon stock in oil palm was greater than that of rubber plants as oil palm has a greater biomass. The greater the plant biomass, the bigger the carbon stock absorbed. Further, the findings revealed that rainfall in dry season has a contribution to carbon stock in oil palm and rubber. The higher the total rainfall during dry season will increase the absorbed carbon stocks.

Abstract

Tanaman tebu (Saccharum officinarum L.) merupakan komoditas yang mempunyai nilai ekonomis yang tinggi di Indonesia. Proses yang terjadi pada tanaman tebu dapat disederhanakan melalui model simulasi. Model simulasi digunakan untuk melihat pengaruh unsur cuaca dan pupuk terhadap perkembangan, pertumbuhan, dan poduktivitas tanaman. Dalam pemupukan yang perlu diperhatikan adalah efisiensi pemupukan. Kekurangan nitrogen akan menyebabkan tumbuhan tidak tumbuh secara optimum, sedangkan kelebihan nitrogen selain menghambat pertumbuhan tanaman juga akan menimbulkan pencemaran terhadap lingkungan. Jika nitrogen yang diserap dari tanah ke tanaman jumlahnya lebih kecil dari pada jumlah kebutuhan nitrogen tanamannya maka sebaiknya tanaman tersebut ditambahkan unsur hara nitrogen. Tahapan kegiatan penelitian terdiri atas 4 tahap yaitu penyusunan konsep model, penentuan nilai peubah dan parameter, input model, penyusunan model simulasi. Interaksi unsur cuaca yaitu curah hujan sangat menetukan kandungan air tanah yang yang berkaitan erat dengan proses mineralisasi (amonifikasi dan nitrifikasi) yang pada akhirnya akan mempengaruhi hasil produksi tanaman tebu. Curah hujan merupakan merupakan faktor yang mempengaruhi perubahan nitrogen dalam tanah. Model simulasi nitrogen ini dapat digunakan untuk menjelaskan proses perubahan nitrogen pada tanah dan tanaman tebu pada tingkat satu kali pemupukan standar. Pada tingkat pemupukan dua kali standar, model tidak dapat digunakan karena model tidak menjelaskan keseluruhan proses yang mempengaruhi.

Abstract

Indonesia is experiencing dynamic land change. One area in Indonesia that has experienced high land use change is Central Cikarang District. Landsat 9 image sensing and land cover data from the Ministry ofEnvironment and Forestry show the increased temperature in the Central Cikarang District area since 2004. Based on the NDVI analysis, the residential area has increased, and the area of green vegetation hasdecreased. Analysis of temperature changes using satellite imagery also shows a wider distribution of hot temperatures in the 2004–2022 range. From the two data analyses that were carried out, a regression test was carried out to determine the correlation between air temperature and vegetation density. The results of the regression test obtained an R2 value of 7.2%. It is also known that the value of the regression coefficient is negative, which means that the correlation of the two data is inversely proportional. So this research analyzes changes in land cover to changes in temperature.

Abstract

Oil palm is one of the important plantation commodities in Indonesia, with a plantation area reaching 14.33 million hectares and continuing to grow. This growth has led to an increase in the number of oil palm processing factories, which produce solid waste of Empty Fruit Bunches (EFB) and liquid waste of Palm Oil Mill Effluent (POME). If not processed properly, this waste can pollute the environment. However, this waste can be used as organic fertilizer that is rich in nutrients, reducing dependence on inorganic fertilizers, and saving costs. At the Rama-Rama Oil Palm Plantation, this waste is used as a soil conditioner and source of nutrients, with the hope of increasing oil palm productivity. This study aims to determine the effect of EFB and POME applications on oil palm productivity by comparing productivity between land applied with EFB and POME using the Independent T Test method at a real level of 5%. The results of observations show that POME and EFB applications affect the production of fresh oil palm fruit bunches, the number of fresh oil palm bunches, and the weight of oil palm bunches. POME application has a greater impact on the production of fresh oil palm fruit bunches, the number of fresh oil palm bunches, and the weight of oil palm bunches compared to EFB application and without POME and EFB application. The average production of fruit bunches in the EFB and POME blocks each month is above its production potential according to the land suitability level of class S2.

Abstract

This study analyzes the latest developments and trends in the field of Mobile Ad-Hoc Networks (MANET) through a bibliometric approach using a metadata dataset from publications taken from Scopus between 2021 and 2024. By utilizing VOSviewer to visualize the data, the study identified key keywords that dominated the MANET literature, such as "security", "routing protocols", "mobility", and "5G". The visualization results show several important clusters, including topics related to network security, vehicle networks (VANET), and the application of advanced technologies such as machine learning in network management. Despite the decline in the number of publications in 2023 and 2024, collaboration between authors continues to show a strong trend. The research also highlights various challenges that are still open problems, such as the development of efficient routing protocols, improving network security, and managing resources in a dynamic MANET environment. In addition to the VOSviewer analysis, further exploration was carried out using the built-in visualization tools from the Scopus web platform to enrich the interpretation of emerging topics and research connections. This was followed by a deeper conceptual mapping using Scopus AI, which provided a visual breakdown of interconnected themes such as security issues, routing protocols, and different network types like VANET and FANET. To complement and validate the findings, the study also incorporated evidence based summaries retrieved from Consensus.app, offering additional insights from AI-driven scientific consensus. This multi-platform approach enhances the reliability of the analysis and provides a more comprehensive view of current and future research directions in the MANET domain.

Abstract

Corn (Zea mays L.) is the most widely cultivated cereal crop globally, serving as a vital source of food, animal feed, and biofuel. Efforts to improve corn production and ensure food security continue through advancements in fertilization and cultivation techniques. This study investigates the effect of different concentrations of AB Mix fertilizer on the growth and anatomical development of corn grown using an efficient floating hydroponic system. The experiment was conducted in a greenhouse at the Cikabayan Bawah Garden, Bogor Agricultural University, Bogor, Indonesia, located at an altitude of 234 meters above sea level. A completely randomized design (CRD) was used, with one factor—AB Mix concentration—at three levels: ½×, 1×, and 2× the standard concentration. Each treatment was replicated six times, resulting in 18 experimental units. Results showed that the 2× AB Mix concentration significantly enhanced plant performance, with a 107% increase in growth compared to the ½× concentration at 4 weeks after sowing (WAS). Parameters such as plant height, shoot fresh weight at 4 WAS, root fresh weight at 3–4 WAS, and total fresh weight at 4 WAS all showed marked improvements with the 2× treatment. These findings indicate that doubling the standard AB Mix concentration is optimal for hydroponic corn cultivation up to 4 WAS. Further studies are recommended to assess the physiological responses and yield outcomes across different corn varieties under varying AB Mix concentrations
