Abstract

The Agroforestry System in Mara Satu village largely follows traditional patterns. The reason the farmers apply the agroforestry pattern has become a local culture that was passed down from their ancestors. The community of farmers is still very dependent on the commodity yields from the agroforestry system, but the community is not aware that agroforestry also affects the local culture, including the attitude of farmers to their environment. Regarding cultural aspects, agroforestry can play a role in tenure aspects, preserving various cultural identities, maintaining local institutions, and preserving traditional knowledge, while looking at farmers attitudes towards the environment, they can assess their attitudes towards grazing forested animals, harvesting forest products and attitudes of agroforestry farmers in maintaining staple plants. so this study aims to determine how the role of agroforestry in local culture and how the attitude of agroforestry farmers to their environment in the village of Mara Satu, Bulungan District. This research was conducted in the village of Mara Satu, Tanjung Palas Barat District, Bulungan Regency, North Kalimantan Province. The methodology used is a purposive sampling method that is deliberate sampling while the determination of the number of samples is determined based on the Slovin technique. Data analysis using quantitative descriptive and loaded in tabular form. Based on the results of the study it can be seen that agroforestry practices developed by farmers in the village of Mara Satu play an important role in protecting farmer's tenure rights, preserving cultural identity, enhancing the role of local institutions, and preserving traditional knowledge. Agroforestry farmers in Mara Satu village can also be said to be quite concerned about their environment. This is evidenced by the majority of agroforestry farmers not tending livestock in the forest and they no longer cut wood in the forest for sale but benefit from non-timber forest products such as swallow nests (Collocalia maxima), aloeswood (Aquilaria malaccensis), lapiu fruit (Archidendron panviflorum) and honey bee (Apis koschevnikovi) from the forest. Besides that, Mara Satu village farmers always take care of their agroforestry staple plants, in this case, durian (Durio zibethinus), as well as they, take care of other forest plants, although the intensity of each respondent varies, because they realize that it is very important to maintain the forest.

Abstract

Forestry development which is oriented towards meeting the raw materials of the forestry industry is one of them with industrial plantations. The types developed are adapted to the needs of the industry and which have high economic value. Eucalyptus pellita F. Muell is one of the fast growing species that is very important for the pulp and paper industry. The advantages of this Eucalyptus as a fast growing plant are short rotation, few disease attacks, many benefits, and high economic value. One of the parameters of vegetative growth is the diameter, which in this case is measured by different stand age classes. So the research aims to determine the effect of age on the distribution of diameters and suspect of relationship patterns. The plant material is derived from clones, namely Clone A which is the result of selection from progeny test which will produce selected clones based on specified criteria and one of them is Clone A which is now a commercial clone since 2012. Propagation through vegetative tissue culture (as mother plant) which is then made shoot cuttings in the stool plant. The study was conducted in HTI PT Surya Hutani Jaya (PT SRH) Sebulu District, Kutai Kartanegara Regency, East Kalimantan Province by determining the research plots by purposive sampling with RAK ​​and 3 replications. Furthermore, doing a diameter census (DSD) and numbering of all tree compilers stands in a circular research plot with an area of ​​0.05 ha, circle radius 12.6 m on stands aged 6 months (0.5 years), 2, 4 and 5 years. The results obtained from this study which are based on the analysis of variance (ANOVA) shows that stand age has a very significant effect on the distribution of diameters, where the results of the BNT 5% test indicate that among the average diameters per age class (6 months, 2, 4 and 5 years) show significantly different from each other. The linear regression relationship between age and diameter distribution of the average stand formed with the equation formed was: Y = 3.96 + 2.2777X, with values ​​R2 = 0.9730 and r = 0.9864.

Abstract

The research aims to analyze supply chain conditions and measure avocado marketing efficiency in Bandungan District, Semarang Regency. The research began in March ₋ June 2020. Methods of research used survey methods. The method of sampling farmers using the purposive sampling method, as much as 40 people. The sampling of marketing agencies was conducted by snowball sampling techniques. A total of 14 people consisted of Pegepul, wholesalers, and retailers. Primary data collection is done by interviews with respondents based on a prepared questionnaire. Data analysis methods used qualitative and quantitative descriptive methods and computation of marketing efficiency. The results showed that the condition of the avocado supply chain in Bandungan district was quite good. The target supply chain is clear, good supply chain structure, resources are adequate, although the implementation of management has not been said to be good, one of them because there is no contractual agreement between marketing institutions so that the amount of avocado sold can not be predicted. The supply chain business process indicates that the product flow in the avocado supply chain moves from the farmer to the consumer, the flow of information goes two-way, i.e. from farmer to consumer or vice versa and the financial flow is moving from consumer to farmer. In the business process, there is a slight obstacle because on the flow of avocado products and information is not yet well integrated, there is no definite cycle so that the delivery time or volume of production can not be predicted well. Marketing activities in the supply chain of the Bandungan district are quite efficient judging from the value of farmer's share (≥ 40%) And the value of the marketing margin of channels 1 Rp 11,800,-, Channel 2 Rp 11,374,-and channel 3 Rp 14,674,-.

Abstract

The Ministry of Agriculture through the Agricultural Quarantine Agency (2019) stated that Robusta coffee has contributed 41% of the country's foreign exchange, with an average export frequency of 102 times per month, and will continue to increase. In connection with the growth in export volume of robusta coffee, coffee farmers need additional substances for the soil in the form of nutrients to be able to meet the soil nutrient needs for coffee from planting to harvest. Organic fertilizer in liquid form is one type of fertilizer that can be an option, in addition to facilitating nutrient absorption. This study aims to determine the response of various liquid organic fertilizers at certain concentrations to the vegetative growth of robusta coffee. The content of C-organic and total Nitogen in the soil which has been given the addition of gamal liquid organic fertilizer and tofu wastewater with the addition of citronella can provide a very significant difference in the vegetative growth of robusta coffee plants at the age of 60 HSP at plant height, and 90 HSP in diameter. stem and number of leaves (strands). Based on the results of laboratory tests carried out, it was also known that the macro and micro nutrient content in the soil with the addition of poc of tofu wastewater which was given citronella had a good content compared to the control and soil conditions with the addition of gamal liquid organic fertilizer.

Abstract

ABSTRACT Organic farming continues to grow in line with the rapid market demand for organic fruit and vegetables. In our country, organic agriculture is experiencing rapid development due to the fact that agricultural products, especially fresh vegetables and fruit, are grown using organic farming systems. Organic agricultural products are starting to attract consumers, especially the upper middle class, who are willing to pay more for food products that are healthy, safe, and environmentally friendly. The purpose of this study was to determine the use of organic fertilizers for washing rice water and pruning water shoots on the growth and yield of tomato plants. The research was conducted in Gunung Kelua village, Samarinda, East Kalimantan for approximately 4 (four) months, from March to July 2020. This study used a randomized block design arranged 3x2 factorial with 3 replications. The first factor is liquid organic fertilizer which consists of 3 (three) levels, including: P0 Without Treatment, P1 (Liquid Organic Fertilizer 250 ml / l water), P2 (Liquid Organic Fertilizer 500 ml / l water). The second factor is pruning water shoots consisting of 2 (two), namely T0 without pruning water shoots on tomato plants, T1 by pruning water shoots on tomato plants. The results showed that the application of liquid organic fertilizer had no significant effect on plant height, but had a significant effect on the number of fruits and production.

Abstract

ABSTRACT Soil fertility in banana cultivation varies and this is what makes Kepok banana production very dependent on it. Banana plants planted in new cleared land originating from the forest are very fertile and are very different from other former crops or bananas. Planting locations in hilly areas away from nutrient-carrying rivers are the last resort due to limited land. This study aims to determine the level of soil fertility on the growth and production of yellow Kepok banana in Samberah, Batu-Batu village, Muara Badak district, Kutai Kartanegara district. Implementation for four months from April to July 2020. The research design used a completely randomized design (CRD) repeated ten times. Fertility levels include former rice fields and former banana plant lands. The results showed that the land formerly planted with bananas was significantly different from the former land planted with rice in the circumference parameter. There was a tendency for the dominance of high parameter data, the number of tillers, and production on former banana plantations. Kepok Kuning banana plants do not choose the location of the land. So that the cultivation of yellow Kepok banana plants can be planted on former banana plantations sustainably.
