Abstract

Fertilizer divided becomes two, namely fertilizer organic and inorganic. According to USEPA, fertilizer organic is applied compost to plants as source nutrients. Fertilizer inorganic is fertilizer result of engineering process by chemical, physical and or biological and the results industry or factory maker fertilizer (Dewanto et al., 2013). Plant need fertilizer to reach production maximum. In research Roidah (2013) there is several of types of fertilizer the observed organic fertilizer cage contains 5 kg N, 3 kg P 2 O 5 and 5 kg K 2 O as well as other essential nutrients in relative amount small. This post aims to know the importance application fertilizer to growth plant cocoa. Based on some of the literature research described could be concluded that fertilizer inorganic and fertilizer organic have advantages as well as deficiencies in several parameters, namely content nutrients, duration nutrient availability, and cost. Application fertilizer inorganic takes to effect real to upgrade production plant cocoa faster and high but no sustainable whereas application fertilizer organic no take to effect real but sustainable. Then, the application of fertilizer on plants cocoa must be combined among fertilizer inorganic and fertilizer organic with composition certain. Application fertilizer inorganic and fertilizer organic in-unit tree plant cocoa need assessment more continue, study more carry on based on age, physiology, type soil, and method application. That thing is in tune with the condition geography in Indonesia which is an archipelagic country so every area has different traits.

Abstract

Coastal abrasion that occurred in Demak Regency caused the loss of agricultural land due to drowning and brought social changes to the community among farmers. In anticipating this, it is necessary to overcome abrasion and increase the social resilience of the community. The ability of GIS in monitoring and mapping the area can be used as a means of useful information for the community. This study uses a quantitative approach. Data processing is carried out using satellite image data with different temporal, namely 1991, 2002, 2012, and 2021. Analysis of shoreline change predictions is carried out using the Digital Shoorelines Analysis System Method. The results of the analysis using the Digital Shoreline Analysis System (DSAS) method found that changes in the northern coastline of Demak Regency tend to experience significant abrasion from year to year. The coastline prediction obtained from the map is known to predict the coastline in the next 10 years the north coast of Demak Regency will experience abrasion. The highest abrasion occurred in Sayung District. Abrasion has an impact on changes in farmers' economic income which changes the behavior of the farming community so that efforts are needed to increase the resilience of the farming community, efforts that can be made include: 1). Prevention of coastal abrasion in areas that have the potential to experience coastal abrasion. 2). Building synergy to increase social resilience between the Government and the community. 3). Build and revive strategic leadership oriented to farmer welfare. The results of the research can also be used as material for consideration in policy making by the relevant government in disaster management efforts that may occur.

Abstract

Bengkalis Regency is located on the north coast of Riau Province, where the coastal area is very vulnerable to the threat of maritime disasters. Global warming can result in natural disasters, which means catastrophe on earth. Global warming causes an increase in the temperature of the earth's surface. This study aims to analyze the progress of the coastline and sea level rise that occurs and their impact on the degradation of Mangrove land on the north coast of Bengkalis Island, Riau Province. The research method used is the quantitative method through analysis of satellite images to map predictions of abrasion in the future. Data processing is carried out using satellite image data with different temporal, namely 1991, 2002, 2012, and 2021. Analysis of shoreline change predictions is carried out using the Digital Shorelines Analysis System Method. Utilization of GIS data can be used to map areas with the potential for abrasion, and make anticipatory measures against abrasion that may occur. In Bengkalis Regency itself, several efforts have been made by the local government, namely through mangrove planting programs, and increasing public awareness.

Abstract

This study aims to obtain information about internal and external factors affecting porang development and obtain porang development strategies in Binjai City. The data analysis method uses the IFE (Internal Factor Evaluation), EFE (External Factor Evaluation) matrix, the IE (Internal-External) matrix, and the SWOT matrix. The results showed that the porang development strategy was an aggressive growth policy strategy by taking advantage of opportunities by using the strengths (SO Strategy) of the porang producers. Some strategies that can be applied are: (1) using social media and e-commerce as a promotional platform to increase customer interest by explaining the good quality of porang, how to cultivate plants that do not require special treatment, and how to process porang tubers into food, (2) the number of exporters and the need for exports are quite large, so the cultivation of porang plants has good potential and prospects in the future and has promising advantages.

Abstract

This study aims to determine the pattern of agarwood marketing channels, and analyze the marketing efficiency of agarwood in CV. Cahaya Gaharu Village Dendang Kec. Stabat. The type of research used is descriptive and qualitative. Determination of the research location is done intentionally or purposively. The analysis technique used is to determine the pattern of marketing channels and calculate marketing margins. The marketing process carried out by CV. Cahaya Gaharu creates a marketing channel, namely CV. Cahaya Gaharu by coming to the farmer's place and buying it according to a predetermined price, then CV. Cahaya Gaharu sells it or markets it domestically or abroad. The marketing margin obtained from the only marketing channel is Rp. 6,980,000 per kilogram of wood, the share margin received is very small, namely 0.29%. This is because farmers sell directly to retailers who sell agricultural products in the country and abroad. Efficiency in the marketing channel of 40% indicates that the marketing channel is less efficient. The lack of efficiency from this business process is due to the many challenges faced, such as transportation costs and harvesting agarwood which takes a long life of up to 7 years, there is uncertainty in harvesting agarwood which can worsen supply.

Abstract

One of the organic waste processing technologies is Eco Enzyme. Eco enzyme is a complex solution of light to dark brown color, which has a fresh sour aroma. Organic waste, in the form of fruit peels, unused fruit flesh, and vegetable pieces, is collected in containers/barrels and then mixed with molasses/brown sugar and water with a certain dose. The recommended dose for the ratio of molasses: organic waste: water is 1:3:10. The fermentation results produce environmentally friendly enzymes and other beneficial elements for agriculture. This study aims to determine the nutrient content of P2O5, K2O, and the C/N ratio of eco enzymes derived from various organic materials. This study used a non-factorial, completely randomized design (CRD). This study used 6 treatment combinations consisting of: P1 = Musa paradisiaca L Boobs (1.5 kg) + Tithonia diversifolia Leaves (1.5 kg); P2 = Musa paradisiaca L weevil (1.5 kg) + Terminalia catappa leaves (1.5 kg); P3= Musa paradisiaca L Weevil (1.5 kg) + Spreading Leaf Shoots (1.5 kg); P4= Mimosa pudica Root (1.5 kg) + Tithonia diversifolia Leaf (1.5 kg); P5 = roots of Mimosa pudica daughter (1.5 kg) + Terminalia catappa leaves (1.5 kg); P6 = Roots of Mimosa pudica (1.5 kg) + Shoots of Spreading Leaves (1.5 kg). The results showed that using organic materials significantly affected the K2O content and the C/N ratio of the eco enzyme.
