Abstract

Penelitian ini bertujuan untuk meningkatkan efektivitas penggunaan arang sekam bakar dan pupuk NPK terhadap pertumbuhan bibit kelapa sawit (Elaeis guineensis Jacq). Metode penelitian yang digunakan adalah eksperimen dengan Rancangan Acak Lengkap (RAL) dengan berbagai perlakuan pemberian arang sekam bakar dan pupuk NPK pada media tanam. Hasil penelitian menunjukkan bahwa kombinasi arang sekam dengan pupuk kandang, khususnya dengan perbandingan 1:1 memberikan kontribusi nyata terhadap peningkatan tinggi bibit kelapa sawit dibandingkan dengan perlakuan lainnya. Analisis statistik menggunakan uji ANOVA menunjukkan bahwa perbedaan perlakuan memberikan pengaruh nyata terhadap pertumbuhan bibit, dengan perlakuan P2 menghasilkan pertumbuhan tertinggi. Temuan ini menggarisbawahi pentingnya penggunaan media tanam yang tepat untuk optimalisasi pertumbuhan bibit kelapa sawit, yang dapat berimplikasi praktis terhadap pengelolaan perkebunan kelapa sawit.

Abstract

Serat Cabolek shows the story which represents the Javanese mysticism, especially as told by the story of Dewaruci. The debate among Haji Amad Mutamakin and Ketip Anom about the spirituality of Dewaruci consist of synthesis Javanese and Islamic mysticism. Particularly, it is the emergence of Hinduism and Islam which shapes Javanese mysticism. Looking carefully at the dialogue and debate between Haji Mutamakin and Ketip Anom about the story of Dewaruci it shows that the concept of Javanese mysticism drawn to the fundamental themes such as what life is what to do in life, and how to live in a good life. Story of Dewaruci shows the significance of batin as an inner essence of a person. The goal of life is seeking water of life that is unity with the Divine. The Divine is not outside there and far from human. The mysticism of Java, therefore, is all about life in the world and human relation with himself, others, and the universe. It is about human activities in all their mundane activities and about human understanding of himself and the universe. Javanese mysticism lays in daily activities. It is in everyday life Javanese coming to the essence of life. These daily activities consist of all relations Javanese made the way of thinking Javanese understood and believed. All aspects become a mystic realm.

Abstract

Controlling rat at the farmer level has a variety of methods, one of which is the use of natural enemies to control the population. Owls were introduced by PPL to farmers as a natural enemy of controlling rats. This research aims to determine the role of PPL in introducing owls as rat control. The role of PPL is assessed by farmers in introducing rat control with owls as communicators, facilitators, motivators and innovators. The results obtained show that farmers assess the role of extension agents as communicators as the highest role of PPL in introducing rat pest control with owls, while their role as facilitators is assessed as the lowest role by farmers. Keywords: Control of mice, owls, natural enemies INTISARIPengendalian tikus di tingkat petani dapat dilakukan dengan berbagai cara, salah satunya adalah dengan memanfaatkan musuh alami untuk mengendalikan populasinya. Burung hantu diperkenalkan PPL kepada petani sebagai musuh alami pengendalian tikus. Penelitian ini bertujuan untuk mengetahui peran PPL dalam memperkenalkan burung hantu sebagai pengendali tikus. Peran PPL dinilai oleh petani dalam memperkenalkan pengendalian tikus dengan burung hantu sebagai komunikator, fasilitator, motivator dan inovator. Hasil yang diperoleh menunjukkan bahwa petani menilai peran penyuluh sebagai komunikator dinilai paling tinggi peran PPL dalam mengenalkan pengendalian hama tikus dengan burung hantu, sedangkan peran sebagai fasilitator dinilai paling rendah perannya oleh petani. Kata Kunci: Pengendalian tikus, burung hantu, musuh alami

Abstract

The success of oil palm cultivation is closely related to the quality of seedlings produced in the nursery phase. This study evaluated the potential acceleration of early growth in oil palm seedlings by optimizing biochar-based growing media combined with organic–inorganic fertilizer formulations. The experiment was arranged in a Completely Randomized Design (CRD) with three treatments: M1 (10 g urea + 50 g organic fertilizer), M2 (10 g NPK + 50 g organic fertilizer), and M3 (10 g urea + 10 g NPK). Each treatment was replicated ten times, resulting in 30 seedlings per replicate. Growth observations were conducted weekly from week 4 to week 20 (approximately four months), covering seedling height, leaf number, and stem diameter. Data were analyzed using one-way ANOVA at a 5% significance level, complemented by effect size analysis (?² and ?²) at week 20 to quantify the biological treatment's influence, and descriptive evaluation of the growth trend. The results showed no significant differences among treatments (p > 0.05). However, all treatments exceeded the physiological growth standards for four-month-old seedlings. M3 produced the highest growth response, with relative increases of 200% in height, 177.8% in leaf number, and 133.3% in stem diameter compared with the standard. These findings suggest that biochar-based growing media, combined with integrated organic-inorganic fertilizer formulations, can enhance early vegetative growth, although statistical significance has not yet been achieved within four months. Further observation up to ten months is recommended to validate the consistency of this growth acceleration.

Abstract

This study examines Indonesia’s immigration policies in managing the mobility of MICE delegates attending international conferences. Delegates’ mobility is a strategic element of business tourism, influencing participant arrival efficiency, travel experience, and overall destination competitiveness. The research analyzes the effectiveness of visa-on-arrival schemes, e-visa mechanisms, conference-specific immigration facilitation, and interagency coordination that supports participant flows. Data were drawn from regulatory reviews, institutional reports, and empirical insights from event organizers. Findings indicate that responsive and integrated immigration policies significantly enhance Indonesia’s attractiveness as a MICE destination, particularly in terms of accessibility, processing time, and procedural certainty. Nevertheless, challenges remain in regulatory harmonization, technological readiness, and policy literacy among stakeholders. This study recommends strengthening event-based immigration service models to improve Indonesia’s competitiveness in the global MICE market.
