Abstract

Kandungan karbon tersimpan terdapat pada permukaan tanah sebagai biomassa tumbuhan, sisa tumbuhan yang sudah mati (nekromasa), maupun dalam tanah sebagai bahan organik tanah. Tulisan ini memaparkan tentang  bagaimana kandungan karbon tersimpan pada hutan primer dan hutan sekunder. Cadangan karbon pada berbagai kelas penutupan lahan di hutan alam berkisar antara 7,5 – 264,70 ton C/ha. Pada hutan primer cadangan karbon berkisar 15,02 – 264,70 ton C/ha. Cadangan karbon terendah terdapat pada hutan bukit kapur dan tertinggi pada hutan alam primer dataran rendah dan dipterokarpa. Hutan alam sekunder  memiliki cadangan karbon berkisar 7,5 – 249,1 ton C/ha, dengan cadangan karbon terendah pada hutan bekas bakaran dan tertinggi pada hutan bekas tebangan. Cadangan karbon hutan alam primer lebih tinggi dari pada hutan alam sekunder yang disebabkan oleh keanekaragaman jenis tumbuhan pada hutan alam primer lebih tinggi dibandingkan dengan hutan sekunder sehingga pengembalian karbon organik ke dalam tanah berjalan dengan cepat dan penyimpanan biomassa hasil konversi karbon bertambah besar seiring dengan semakin banyaknya karbon yang diserap pohon tersebut.

Abstract

Mangrove ecosystems have an important role in maintaining the balance of the coastal environment. However, its existence is increasingly threatened by human activities and climate change. Effective monitoring and preservation of mangrove ecosystems is crucial. Kota Pari Village, with its mangrove potential, needs an innovative system to support these efforts. Therefore, this study aims to develop a QR Code-based Mangrove Monitoring Information System application "SIPEMANG". This application is designed to facilitate monitoring mangrove conditions, collecting data on mangrove species, and involving the community in mangrove conservation. Community involvement is not only the community around the village of Pari City but through the application can reach community involvement around the world. QR Codes placed on each mangrove tree allow quick access to specific information about the mangrove tree. The data collected through the application will be processed and analyzed to provide the latest information about the condition of the mangrove ecosystem in Kota Pari Village. So in addition to mangrove planters, the next important thing is to ensure that mangroves grow and develop properly. It is hoped that the SIPEMANG application can be an innovative solution in supporting the monitoring and preservation of mangrove ecosystems in a sustainable manner.

Abstract

Shallots (A. ascalonicum) are a horticultural commodity that has high economic value in Indonesia and is widely used, both as a cooking spice and traditional medicine. The purpose of this study was to determine the effect of banana peel POC and rice husk charcoal growing media on the growth of shallots and to assess whether there is an interaction between the two factors. The research activities were carried out in the experimental field of Panca Budi Development University located in Sampe Cita Village, Kutalimbaru District, Deli Serdang Regency, North Sumatra Province at an altitude of 149 meters above sea level. The research implementation period was from November 2025 to January 2026. The method used was a 4x4 Factorial Randomized Block Design (RAK) with two factors resulting in 16 treatment combinations repeated in 3 blocks for a total of 48 plots. The first factor was Banana Peel POC with 4 levels, namely: F0 = Without POC, F1 = 100 ml/plot, F2 = 200 ml/plot, F3 = 300 ml/plot. The second factor of 4 Level Rice Husk Charcoal Planting Media is: H0 = Top Soil, H1 = Top Soil: Rice Husk Charcoal (3:1), H2 = Top Soil: Rice Husk Charcoal (1:1), H3 = Top Soil: Rice Husk Charcoal (1:3). The results of the study showed that the treatment of banana peel POC significantly affected the growth of shallot plants in plant height, number of leaves, number of tillers/sample, wet weight/sample, dry weight/sample and dry weight/plot, the best results in treatment F1 = 100 ml/plot. The treatment of rice husk charcoal planting media also significantly affected the growth of shallot plants in plant height, number of leaves, number of tillers/sample, wet weight/sample, dry weight/sample, but did not significantly affect the dry weight parameter/plot, the best results in treatment H1 = top soil: rice husk charcoal (1:3). There was no interaction between banana peel POC and rice husk charcoal planting media on the growth of shallots (A. ascanolicum).

Abstract

This study aims to determine the effectiveness and efficiency of weed spraying using drone technology compared to conventional spraying methods in sugarcane plantations. Weed control is an important component of sugarcane cultivation because excessive weed growth can compete with the main crop for nutrients, water, light, and growing space, thereby potentially reducing productivity. The research employed a comparative method by evaluating two herbicide application techniques, namely the use of a knapsack sprayer and a drone sprayer. The parameters observed included the speed of weed mortality, effectiveness of herbicide application, and operational efficiency of each spraying method. The results showed a significant difference between the two herbicide application techniques. The drone sprayer demonstrated higher operational efficiency because it was able to control weeds more rapidly, achieving a weed mortality rate of 98% on the 12th day after herbicide application. In comparison, the knapsack sprayer reached a weed mortality rate of 99% on the 21st day after application. These findings indicate that drone-based spraying can accelerate weed control while reducing application time and potentially minimizing labor requirements. Therefore, drone sprayers have strong potential to be applied as a more efficient weed management technology in sugarcane plantations.
