The Oncidium sphacelatum orchid, commonly propagated vegetatively through pseudobulb separation, presents opportunities for further research into propagation methods and organic fertilizer application. This study, conducted in Batu City, aimed to explore the interaction between vermiwash concentration and shoot number on aeroponically cultivated Orchid sphacelatum Lind cuttings, as well as individual treatment effects. Employing a factorial RKLT design with shoot number (one or two) and vermiwash concentration (100, 200, or 300 ml/L) as factors, the study evaluated plant height, leaf count, stem length, shoot length, root count, and root length as variables. Data analysis involved ANOVA and BNJ tests. Results revealed that cuttings with two shoots and a 200 ml/L vermiwash concentration promoted optimal leaf growth. The number of shoots influenced shoot length, with two shoots demonstrating superior growth compared to single shoot cuttings. Interestingly, vermiwash concentration did not significantly impact shoot growth parameters, indicating that its effects may be limited in this context. This study sheds light on the potential benefits of using vermiwash in orchid cultivation, particularly in enhancing leaf growth when combined with multiple shoot cuttings. However, further investigation is needed to understand the nuanced effects of vermiwash on other growth aspects and its interaction with different propagation methods.Overall, the findings contribute to the optimization of orchid propagation techniques, providing valuable insights for orchid growers seeking to enhance plant growth and productivity sustainably. Further research could delve deeper into the mechanisms underlying the observed effects and explore additional variables to refine cultivation practices for Oncidium sphacelatum orchids.

One of Indonesia's centres of pepper plant yields is Lampung Province. The productivity of the pepper is decreasing. Pepper productivity is declining, so selecting the right crop system, according to the needs of the microclimate of pepper plants, is needed to produce optimal productivity. This research aims to study the microclimate variations of several agroforestry systems, analyze the relationship of microclimate productivity, determine the ideal type, and evaluate the level of pepper productivity in various systems. This research was conducted in Aji Kagungan Village, Abung Kunang District, North Lampung Regency, at 450-1500 meters above sea level in January-April 2019. The research method used was survey purposive sampling, which considered the uniformity of the age of pepper plants and differences in the types of vegetation that make up the system. The data observed were microclimate, land condition, and productivity of pepper plants. Data was collected on five types of systems divided into four zones. Each zone has four observation points, observations were made 8 times with an interval of 10 days. The results showed that the determinants of microclimate diversity of pepper agroforestry systems were canopy area, density, frequency, and vegetation. In contrast, the magnitude of sunlight transmission, temperature, and humidity in pepper agroforestry systems was influenced by vegetation characteristics. The form of relationship formed by the transmission of sunlight and air temperature is positive linear, while the humidity of the air forms a negative linear relationship to the productivity of pepper plants in the agroforestry system tested while of the five types of agroforestry systems tested. Type 5 is the ideal pepper agroforestry system. Where the microclimatic conditions formed by Type 5 can produce the highest pepper productivity among other system types

This study examines the role of asset legality and land management in strengthening agrarian reform, particularly its impact on the welfare of smallholder farmers in Indonesia. The main objectives of this study are to evaluate the effectiveness of regulations that support farmer empowerment and to formulate an integrative strategy to promote sustainable agrarian justice. This study looks at laws and regulations, checks how they are put into practice, and measures how well these policies help reduce unfairness in owning and accessing land and resources. The results show that programs such as Complete Systematic Land Registration (PTSL) play an important role in accelerating the legalization of land assets but have not fully addressed the challenges of legal uncertainty and weak land management. Legal land ownership has been shown to increase smallholder farmers' access to financing and subsidies, while effective land management contributes to increased productivity and sustainability. To realize inclusive agrarian reform, cross-sectoral synergy is needed through bureaucratic simplification, fair land redistribution, technical training, and strengthening the role of the National Land Agency (BPN) and developing a community-based land management model. Penelitian ini mengkaji peran legalitas aset dan manajemen lahan dalam memperkuat reforma agraria, khususnya dampaknya terhadap kesejahteraan petani gurem di Indonesia. Tujuan utama studi ini adalah mengevaluasi efektivitas regulasi yang mendukung pemberdayaan petani serta merumuskan strategi integratif untuk mendorong keadilan agraria secara berkelanjutan. Dengan menggunakan pendekatan normatif-empiris dan metode deskriptif-analitis, dengan menganalisis peraturan perundang-undangan, mengevaluasi implementasinya di lapangan, dan menilai sejauh mana kebijakan mampu mengatasi ketimpangan kepemilikan serta akses terhadap sumber daya agraria. Hasil penelitian menunjukkan bahwa program seperti Pendaftaran Tanah Sistematis Lengkap (PTSL) berperan penting dalam mempercepat legalisasi aset tanah, namun belum sepenuhnya menjawab tantangan ketidakpastian hukum dan lemahnya pengelolaan lahan. Kepemilikan tanah yang sah terbukti meningkatkan akses petani gurem terhadap pembiayaan dan subsidi, sementara manajemen lahan yang baik berkontribusi pada peningkatan produktivitas dan keberlanjutan. Untuk mewujudkan reforma agraria yang inklusif, diperlukan sinergi lintas sektor melalui penyederhanaan birokrasi, redistribusi tanah yang adil, pelatihan teknis, serta penguatan peran Badan Pertanahan Nasional (BPN) dan pengembangan model manajemen lahan berbasis komunitas.
