Abstract

Nitrogen (N) fertilization in coffee agroforestry system requires proper management to increase N use efficiency (NUE) and minimize N losses. This study investigated the impact of different fertilization management on N losses, N uptake, and N storage in a coffee-based agroforestry system. The study was conducted using three types of fertilizer (organic, inorganic, and mixture of organic-inorganic) with three doses (low, medium, and high), and a control treatment (no fertilization), with 3 replications. Soil leachate was collected using lysimeter at 50 cm depth (below coffee root zone) and gas emissions were collected monthly using chamber for 4 months. Soil sample at 0-20 cm depth and leaf sample were also collected. The variables included NH₄⁺ and NO₃ˉ concentration in the leachate and soil, soil N total, N uptake, N emission, N use efficiency (NUE) and partial N balance. Results showed no significant differences in N leaching or plant N uptake across treatments. However, the mixed fertilizer with high dose treatment significantly increased soil N availability while reducing N₂O emissions and improving the overall N balance. This suggests that a high dose mixed fertilizer application can enhance N utilization in coffee-based agroforestry systems, potentially improving productivity while minimizing environmental impacts. Keywords: Agroforestry, Fertilization, Nitrogen balance, Nitrogen loss, Nitrogen storage.

Abstract

Application proper type and dose of fertilizer will maintain soil fertility and help coffee growing better in the agroforestry system. Mis-management in fertilization compromises soil quality, and therefore it is underscoring the imperative to ascertain proper type and dosage of fertilizer for maintaining soil properties and nutrient storage. The study aims to assess and evaluate the role of fertilizer management in influencing soil properties, nutrient stocks, and leaf nutrient content. The field experiment was conducted in smallholder coffee agroforestry systems East Java – Indonesia. A randomized block design including a control plot in the protected area and nine combinations of fertilizer types (i.e., organic, inorganic, and mixed) and doses (i.e., low, medium, and high), with three replications, was applied to coffee trees in an agroforestry system. This study proves that differences in fertilizer management did not significantly changes soil physical properties (i.e., soil bulk density and total porosity), indicated that changing in soil physical properties occurred in the long time. In addition, the reduced fertilizer dose (the low dose fertilizer application) had comparable soil available P, and higher soil exchangeable K and soil P stock as compared to those in the protected areas. The study revealed that applying low-dose mixed fertilizer management effectively improved soil fertility.

Abstract

Lead (Pb) is a toxic heavy metal for humans. Agrochemical applications contribute to Pb contamination and accumulation in plants which is harmful to humans. This study aims to investigate the habits of horticultural farmers in applying inorganic fertilizers and pesticides intensively on Pb concentration in the soil and cultivated plants, and its effect on plant growth. The measured parameters consisted of soil and plant Pb content, soil pH, organic C, total N, available P, and exchangeable K. This study used a randomized block design consisting of 4 treatments (Control (KT); (PR); (TN); and (TP)). The results showed that horticultural farmers' dosage of inorganic fertilizers exceeded Indonesia Ministry of Agriculture recommendation. The application of inorganic fertilizers and pesticides by farmers (business as usual) increased Pb content in plants up to 31.46 mg/kg. Besides the application of inorganic fertilizers increases fertilizer residues in the soil by up to 65%, which increases environmental pollution even though the application of inorganic fertilizers increases plant growth and production (shoot length,  the number of leaves, and plant dry weight). Thus, wisely applying agrochemicals is required in order to support plant growth and production without further environmental problems.

Abstract

This research aims to analyze the urgency of setting a minimum amount of debt as a requirement in bankruptcy applications in Indonesia by comparing it with the minimum amount of debt regulation in the United States. This type of research is normative legal research. The results of this research conclude that there is an urgency to regulate further bankruptcy requirements because the consequences of bankruptcy are very large for debtors, and Supreme Court Regulation Number 14 of 2019 concerning Procedures for Settlement of Simple Claims can be used as a reference in regulating the minimum amount of debt in the bankruptcy and the regulation of bankruptcy law in the United States, the US Bankruptcy Code is more comprehensive and responsive because it regulates the minimum amount of debt which is adjusted to the type of debtor who is going to file for bankruptcy. In contrast, Indonesia does not restrict the minimum amount of debt.Keywords: the minimum amount of debt, bankruptcy requirements, debtor AbstrakPenelitian ini bertujuan untuk menganalisis urgensi pengaturan minimal utang sebagai persyaratan dalam permohonan pailit di Indonesia dengan melakukan perbandingan dengan pengaturan minimal utang di Amerika Serikat. Jenis Penelitian ini merupakan penelitian hukum normatif. Hasil penelitian menyimpulkan bahwa adanya urgensi untuk mengatur syarat kepailitan lebih lanjut karena akibat pailit yang sangat besar bagi debitor dan Peraturan Mahkamah Agung Nomor 14 Tahun 2019 tentang Tata Cara Penyelesaian Gugatan Sederhana dapat dijadikan sebagai acuan dalam mengatur jumlah minimal utang dalam kepailitan dan pengaturan hukum kepailitan di Amerika Serikat dalam US Bankruptcy Code lebih komprehensif dan responsif karena memiliki pengaturan jumlah minimal utang yang disesuaikan dengan jenis debitor yang akan dimohonkan pailit, sedangkan Indonesia tidak mengatur jumlah minimal utang.Kata Kunci: jumlah minimal utang, syarat kepailitan, debitor.

Abstract

The concept of eco-culture has a sustainability paradigm that emphasizes the harmony of humans and ecosystems. The target is the strengthening of local characters through the study of local genius, as well as the application of science and technological innovation in managing the potential for improving the quality of the environment and humans. Increasing the economy through tourism is its added value. Kampung Baran has a unique ethnographic and geographical setting inhabited mostly by low-income people. The potential that can be developed is agriculture which is now slowly starting to be abandoned. This study examines the application of the eco-culture concept which consists of an image of space, an image of building, and an idealized concept of place for the development of Kampung Baran. Through a descriptive-phenomenological study, the researcher explores the physical-spatial-architectural and economic-social-cultural phenomena of Kampung Baran as the object of study. Furthermore, the study of the application of the concept of eco-culture in the village of Baran was carried out through a SWOT analysis. The results obtained indicate that the concept of eco-culture can be applied in Kampung Baran by emphasizing on strengthening the noble values of the culture of agrarian communities in the expression of tangible and intangible heritage that is adaptive to cultural dynamics and strengthening and developing local potential.

Abstract

Tree management such as pruning of coffee canopy and fertilization in coffee-based agroforestry systems plays a crucial role in reducing nutrient losses through leaching. This study aims to evaluate the impact of coffee pruning and fertilization management on nutrient leaching. The study was conducted in a coffee agroforestry system in the Universitas Brawijaya forest from February to August 2023. This study used a split-split plot design with main plots of coffee canopy pruning (T1: pruned coffee, T2: unpruned coffee), subplots of fertilizer type (O: organic fertilizer, A: inorganic fertilizer, M: 50% organic + 50% inorganic), and sub-plots of fertilizer dosage (D1: dosage based on farmer practice, D2: recommended dosage based on the Coffee and Cocoa Research Center, D3: dosage based on the replacement of nutrients removed by the coffee bean harvest). The study had 18 treatments with 4 replicates, resulting in 72 experimental plots. The variables measured included ammonium, nitrate, phosphorus, and potassium concentrations. Sampling of nutrient leaching was conducted four times over a period of six months (February-July), specifically in February, March, April, and July 2023 at 0.5 m distance from the coffee stem in 0.6 m depth of soil. The results showed that pruning coffee plants had a significant effect (P < 0.05) on nutrient losses due to leaching, especially nitrate and potassium. A pruned coffee canopy in an agroforestry system was able to reduce nitrate and potassium leaching by 30% and 13%, respectively, compared to unpruned coffee in the agroforestry land. Nutrient loss of phosphorus through leaching was found to be 21% greater in treatment D1 compared to D2. However, this study did not find a significant effect of the interaction between pruning and fertilization in reducing the leaching of nitrogen, phosphorus, and potassium nutrients.
