Get PDFABSTRACT
Sungkai (Peronema canescens Jack) is a locally significant commercial species whose wood production is currently declining. Therefore, it is essential to implement development and cultivation measures to enhance the production of roundwood, which can be achieved through the development of plantation forests. Palm Oil Empty Fruit Bunch Compost (TKKS) is an organic fertilizer that can be applied to ultisol land designated for planting sungkai. TKKS compost contains essential nutrients required by the soil and plants, specifically N 15%, P 0,5%, K 7,3%, and Mg 0,9%. This study employed a Randomized Block Design (RBD) based on a slope gradient of 9%. The design consisted of six treatments with four experimental groups, resulting in a total of 24 experimental plots. Each plot contained nine plants, three of which were designated as samples. The treatments tested included varying doses of TKKS compost: b0: no TKKS compost, b1: 2 kg per planting hole, b2: 4 kg per planting hole, b3: 6 kg per planting hole, b4: 8 kg per planting hole, and b5: 10 kg per planting hole. The results indicated that the application of TKKS compost improved the physical and chemical properties of the soil, including pH, organic carbon, bulk density, and soil total nutrient content. Furthermore, the application of TKKS compost significantly enhanced the growth parameters of sungkai, such as height, diameter, leaf count, dry weight of the canopy, and dry weight of the roots, with the best treatment being b2 (4 kg per planting hole).

Pengaruh Pemberian Pupuk NPK Terhadap Pertumbuhan Bibit Kaliandra Merah (Calliandra Calothyrsus Meissn) Pada Media Ultisol: The Effect of NPK Fertilizer Application on The Growth of Red Calliandra Seedlings (Calliandra calothyrsus Meissn) on Ultisol Media
Get PDFABSTRACT
Red caliandra (Calliandra calothyrsus Meissn) is a plant that belongs to the Fabaceae family. Callindra has a rapid growth rate, reaching a height of 3-5 meters in the first year on suitable land. The planting medium commonly used for seedlings includes ultisol soil, which generally has sensitive aeration pores and low stability index, causing the soil to easily become compacted. The growth of quality calliandra seedlings in the nursery is influenced by soil fertility; therefore, additional treatment in the form of fertilizer is necessary to ensure sufficient nutrient content. One of the fertilizers that can be used is the NPK compound fertilizer. This fertilizer is one of the inorganic fertilizers that is very efficient in increasing the availability of macro nutrients N, P, and K. This research was conducted in the Forest Cultivation Laboratory of the Faculty of Agriculture, Jambi University, using the Completely Randomized Design (CRD) method with one factor, namely the NPK fertilizer 15:15:15. The treatments given were: P0 (without treatment), P1 (NPK 1 grams), P2 (NPK 2 grams), P3 (NPK 3 grams), P4 (NPK 4 grams), and P5 (NPK 5 grams). Observation parameters include height increase, diameter, leaf count, root dry weight, and shoot dry weight. Based on the research results, it can be concluded that the application of NPK fertilizer has no significant effect on the growth of calliandra seedlings in ultisol media, as observed in all parameters. The application of NPK at certain doses does not yield optimal results in the growth of callindra seedlings.

ABSTRAK
Kaliandra merah (Calliandra calothyrsus Meissn) merupakan tanaman yang termasuk ke dalam famili fabaceae. Kaliandra merah memiliki pertumbuhan yang cepat, ditahun pertama tingginya dapat mencapai 3-5m pada lahan yang memadai. Media tanam bibit yang banyak digunakan diantaranya adalah tanah ultisol yang umumnya peka memiliki pori aerasi dan indeks stabilitas rendah sehingga menyebabkan tanah mudah menjadi padat. Pertumbuhan bibit kaliandra yang berkualitas di persemaian dipengaruhi oleh kesuburan tanah, dengan demikian perlu perlakuan tambahan berupa pupuk agar unsur hara mencukupi. Salah satu pupuk yang dapat digunakan adalah pupuk majemuk NPK. Pupuk ini merupakan salah satu pupuk anorganik yang sangat efisien dalam meningkatkan ketersediaan unsur hara makro N, P, dan K. Penelitian ini dilaksanakan di Laboratorium Budidaya Hutan Fakultas Pertanian Universitas Jambi dengan menggunakan metode Rancangan Acak Lengkap (RAL) 1 faktor yaitu pupuk NPK 15:15:15. Perlakuan yang diberikan yaitu: P0 (tanpa perlakuan), P1 (NPK 1 gram), P2 (NPK 2 gram), P3 (NPK 3 gram), P4 (NPK 4 gram), dan P5 (NPK 5 gram). Parameter pengamatan berupa pertambahan tinggi, diameter, jumlah daun, berat kering akar, dan berat kering tajuk. Berdasarkan hasil penelitan, dapat disimpulkan bahwa pemberian pupuk NPK berpengaruh tidak nyata terhadap pertumbuhan bibit kaliandra merah pada media ultisol yang terlihat pada semua parameter. Pemberian NPK dengan dosis tertentu tidak memberikan hasil optimal pada pertumbuhan bibit kaliandra merah.

Evaluasi Status Kesuburan Tanah dan Kesesuaian Lahan Jelutung Rawa (Dyera Lowii Hook. F) : Evaluation of Soil Fertility Status and Land Suitability of Jelutung Rawa (Dyera Lowii Hook. F)
Get PDFABSTRACT
Jambi Province is one of the regions in Indonesia with a fairly extensive peat forest area, spread across several districts, including Muaro Jambi Regency and Tanjung Jabung Timur Regency. In recent years, the peat swamp forests in this area have experienced degradation, primarily due to land fires. One important conservation area is the Orang Kayo Hitam Grand Forest Park, which is dominated by a peat swamp forest ecosystem with high plant diversity. The main problem faced is the decline in peat soil quality after the fire, which impacts the success of rehabilitation activities. This study aims to evaluate the status of soil fertility and land suitability for the growth of swamp jelutung on post-fire peatlands. The results show that the soil fertility status at the study site is still quite good, but there are main limiting factors in the form of nutrient retention and low potassium availability. Under these conditions, the current land suitability class is quite suitable (S2) and can be improved to very suitable (S1) with moderate management by adding 150-200 g of dolomite per planting hole to increase soil pH and adding 180.34 g of KCl single fertilizer per planting hole for peat soil with a BV of 0.2.

The dynamics of Indonesian language adaptation in virtual communication among Generation Z using acronyms, abbreviations, and code-mixing
Get PDFThe primary objectives of this research were to identify the dominant patterns of acronyms and abbreviations, analyze the linguistic and social factors underlying their usage, and evaluate the impact of this phenomenon on the effectiveness, clarity, and communication norms among Generation Z in Bali. The research employed a sequential explanatory mixed-methods design, involving 450 respondents aged 13-28 years. The research findings indicated a high prevalence of acronyms and abbreviations in Gen Z's communication. The ten most dominant acronyms, such as "baper" (16.1%), "pansos" (12.6%), and "bucin" (11.2%), not only serve an efficiency function but also possess rich pragmatic implications. Similarly, abbreviations like "yg" (18.7%), "udah" (16.3%), and "ga" (15.1%) are frequently used, reflecting a strong preference for typing efficiency. Analysis also revealed that code-mixing occurred in 68.3% of the conversations examined, with lexical insertion (75.2%) being the most dominant type. The primary motivations behind these linguistic adaptations include a strong drive for communicative efficiency (saving typing time), the need to construct identity and foster in-group affiliation, and aspirations towards modernity and globalization
ACTIVE AGING AMONG THE ELDERLY AND ITS ECONOMIC AND SOCIAL CONSEQUENCES IN BULGARIA
Get PDFThis study investigates the multidimensional factors contributing to active ageing among older adults in Bulgaria and examines its broader implications for the country’s social and economic development. Moving beyond traditional notions of ageing as a period of dependency and withdrawal, active ageing is framed here as a dynamic process that empowers older individuals to remain healthy, socially engaged, and economically productive. The novelty of this research lies in its integrative approach, combining sociological, economic, and technological perspectives to assess how ageing can be redefined as an opportunity rather than a burden. By evaluating key determinants—such as physical and mental health, intergenerational relationships, social integration, economic security, lifelong learning, and digital inclusion—the study provides a holistic understanding of what enables active participation in society later in life. Particular emphasis is placed on Bulgaria’s unique demographic context, marked by accelerated population ageing, a declining working-age population, and high rates of youth outmigration. These challenges intensify the need for effective policies and community-based interventions that promote independence, dignity, and lifelong contribution. The analysis highlights that active ageing is not only shaped by personal capacity but also by the accessibility of public services, the inclusiveness of social networks, and the digital readiness of the elderly population. Furthermore, the study underscores how societal attitudes toward older people influence their opportunities for social inclusion and economic engagement. By identifying enablers and barriers, this research offers actionable insights for policymakers aiming to strengthen Bulgaria’s resilience in the face of demographic change through inclusive, age-positive development strategies
