Peat characteristics include low fertility, high acidity, and poor drainage because it comes from the weathering of organic matter under anaerobic conditions. However, peat has environmental benefits such as absorbing carbon, water buffers, and providing habitat for various unique flora and fauna. The use of peat as agricultural land is widely used by farmers in Pontianak City because it has a very large peatland area with a traditional agricultural system. However, traditional farming will have local knowledge (local wisdom) as a way to minimize damage to the peat ecosystem as an adaptation effort. This study aims to examine the adaptation of peatland management in traditional farming in Pontianak City. The method used in this study is qualitative descriptive and multiple linear regression analysis. The number of research samples was 68 farmers. The results of the study showed that traditional farmers have paid attention to the sustainability of their farming to minimize environmental damage. The results of the study showed that the adaptations carried out were making wells to maintain water availability, using short-lived vegetables that require shallow drainage of 20-30 cm and are adaptive to peat, providing intensive shade, planting trees on empty land, cleaning intensive irrigation, providing ameliorant ash, lime, chicken manure intensively, and arranging planting patterns with diversification. The determining factors for peatland management adaptation include age, land area, length of farming, participation of fire-conscious communities, and intensity of participation in outreach.

Belawa Village, located in Lemahabang District, Cirebon Regency, West Java, is famous for the Labi-labi Belawa tourist attraction. This study aims to develop a sustainable tourism village at the Cikuya Tourist Attraction in Belawa Village. This model is expected to be an integrated solution to support the implementation of sustainable tourism. The research method used is descriptive qualitative, with quantitative data analysis. The results of the study show that the implementation of sustainable tourism in Cikuya is evident through environmental preservation and the conservation of the Belawa turtle habitat. Although the management is not yet optimal, there are practices of utilizing organic waste, such as chicken manure for animal feed and coconut shells for souvenirs, supporting the circular economy concept. Community participation in cultural activities also supports the social and cultural aspects of sustainable tourism, although it is still incidental and has not yet been programmed sustainably. However, the implementation of sustainable tourism in Cikuya is not yet fully optimal, despite having strong natural and conservation potential. Structural and operational barriers, such as accessibility, human resources, institutional governance, economy, socio-culture, and policy support, affect the effectiveness of applying sustainability principles.

This study examines the effectiveness of organic fertilizers in improving the quality and yield of cucumber (Cucumis sativus L.) plants through a comprehensive literature study. A systematic review was conducted on recent scientific publications that discuss various types of organic fertilizers, including chicken manure, bokashi, organic liquid fertilizer, and eco-enzyme. The research method used a literature study approach by analyzing articles from 2020-2024, focusing on the effectiveness of organic fertilizers in increasing the growth and productivity of cucumber plants.The results showed that organic fertilizers do not merely provide nutrients, but transform as agents of soil ecosystem regeneration. Each type of organic fertilizer has a unique mechanism in influencing plant growth, including increased microbiological activity, optimization of soil structure, and stimulation of the root system. Variations in plant responses depend on genotype, fertilizer composition and environmental conditions. The research resulted in practical recommendations for sustainable organic fertilization strategies, emphasizing the importance of a precision and holistic approach in cucumber crop nutrient management. The findings make a significant contribution in the development of sustainable agriculture.

Asnan Ridoanrisna. Efficiency Of Pakcoy Plants (Brassica Rapa) In Maintaining Water Quality To Support The Survival Rate Of Tilapia. Under Guidance By Robin And Novita Mz. Tilapia is a freshwater fish commodity with high economic value. According to data from the Central Bureau of Statistics (BPS), tilapia exports reached 12.29 thousand tons with a value of USD 78.44 million. Tilapia farming faces the risk of mortality which can lead to economic losses, one of which is caused by organic pollution. To address this issue, this research employs phytoremediation methods with varying plant densities to improve water quality and tilapia survival. The study was conducted with four treatments: A75 (plant density 75% of the aquarium surface area), A50 (50%), A25 (25%), and A0 (no plants), using an aquarium size of 60 x 30 x 50 cm³. Each treatment received chicken manure at 1.8 grams per aquarium and 40 tilapia fish per aquarium. Observations were made over 15 days in March 2023, measuring physical and chemical water parameters including DO, pH, TDS, temperature, and ammonia, as well as calculating the survival rate of tilapia. Using a Completely Randomized Design (CRD), the study found that treatment A75 achieved the highest survival rate at 62.5%. This result indicates that higher plant density in the phytoremediation method is more effective in maintaining water quality and supporting tilapia survival.

This study aims to analyze Azolla sp liquid organic fertilizer and chicken manure. Tests on shallot plants were carried out to see the effect of organic fertilizer on growth and yield. The research method used a factorial Randomized Block Design (RAK) consisting of 2 factors with 16 combinations and 3 blocks. The first factor is the provision of azola liquid organic fertilizer consisting of 4 levels : 0 ml/l water/m2, 200 ml/l water/m2, 400 ml/l water/m2, 600 ml/l water/m2. The second factor is the provision of chicken manure consisting of 4 levels : 0 kg/m2, 0.5 kg/m2, 1.0 kg/m2 and 1.5 kg/m2. Azolla liquid organic fertilizer contains 0.03% total N, 0.11% P2O5, 0.59% K2O, 1.44% organic C, and 3.88% pH. The results of chicken manure analysis contain 1.73% Nitrogen (N), 1.45% Phospor (P), 1.12% Potassium (K), and 18.15% Organic C. Both types of fertilizers do not meet the minimum technical requirements for SNI organic fertilizers. The provision of azola liquid organic fertilizer has a significant effect on the parameters of the number of tillers, number of bulb/m2, wet weight of bulb/m2, and  dry weight of bulb/m2. The provision of azola liquid organic fertilizer 600 ml/liter of water/m2 has the best effect on all observation parameters. The provision of chicken manure has a significant effect on the parameters of plant height, number of leaves, number of shoots, number of bulb/m2, wet weight of bulb/m2, dry weight of bulb/m2. The dose of chicken manure 1.5 kg/m2 showed the best effect for all observation parameters. The interaction of the provision of liquid organic fertilizer azolla and chicken manure was not significantly different in all treatments.

Organic fertilizers are materials derived from plant residues, and animal waste, both those that have undergone decomposition and those that are undergoing a decomposition process that functions to add nutrients. Substantially organic fertilizers are composed of humus and non-humus materials so that they can improve marginal soils and sand-dominated soils. The purpose of this study was to determine the effect of various organic fertilizers on sand planting media, and to determine the growth response of pakcoy on various types of organic fertilizers. The research was conducted at the Field Laboratory I Experimental Garden and Agrotechnology Laboratory of the Faculty of Agriculture, Halu Oleo University, the research took place from September to November 2020. This study was arranged in a randomized group design (RAK) with the treatment of various organic fertilizers, which were divided into; no organic fertilizer/control (B0), cow manure (B1), chicken manure (B2), comba-sheep green manure (B3), calopogonium green manure (B4). Each treatment was repeated four times as a group, resulting in 20 experimental units. Each experimental unit consisted of six polybags, resulting in a total of 120 polybags of pakcoy plants. The variables observed were plant height, number of leaves, fresh weight and dry weight of pakcoy plants. The results showed that organic fertilizer had a very significant effect on all observed growth variables of pakcoy plants. Cow manure treatment in the first and second week plant height variables showed the highest value (5.04 cm, and 6.71 cm). But in general, in the third to fifth week, the average chicken manure gave the highest growth response on the variable of plant height, number of leaves, fresh weight and dry weight of pakcoy plants.
