Lettuce plants in the process of growth and development require additional nutrients by repair Techniques for cultivation and repair of organic or inorganic fertilizers. Organic fertilizers are also called natural fertilizers because all or most of them come from natural fertilizers. This study aims to (i) find out the effect of giving dung manure to the growth and yield of lettuce on swampy soil, (ii) get the best dose from the administration of duck manure to the growth and yield of lettuce on swampy swamp soil. This research was conducted in Hambuku Tengah Village, Sungai Pandan District from April to June 2010. Using a Completely Randomized Design (CRD). The factors studied were 9 doses of duck manure fertilizer dosage with 9 treatments, there are b0 = 0 t.ha-1; b1 = 2,5 t.ha-1;  b2 = 5,0 t.ha-1;  b3 =  7,5  t.ha-1;  b4 = 10 t.ha-1 ; b5 = 12,5 t.ha-1; b6 = 15,0 t.ha-1; b7 = 17,5 t.ha-1; b8 = 20,0 t.ha-1 with 3 replications, thus there were 27 experimental units. The observed variables were plant height and number of leaves aged 14, 21, 28 and 35 days after planting (DAP) and leaf wet weight at harvest. From the results of the study there was a response of tall mustard plants aged 28 HST and wet weight of mustard plants but there was no response to the height of mustard plants aged 14, 21 and 35 HST on the administration of duck manure, with the best dose was treatment b4 (10 t.ha -1)

Alabio’s yam (Dioscorea alata L.) is a potential carbohydrate source that can be developed to meet food needs, especially in swamps and in dry areas. The use of organic fertilizers is believed to bring more benefits to agricultural production. Bokashi water hyacinth is compost which contains humic acid which can increase seed germination, stimulate plant growth, increase soil fertility, increase yield and produce phytohormone compounds that can accelerate root growth. This study aims to (i) determine the effect of adding water hyacinth bokashi to vegetative and generative performance of alabio sweet potatoes on lebak swamp and (ii) to obtain the best dose of bokashi water hyacinth on vegetative and generative performance of sweet alabio on lebak swamp. This research was conducted in Sungai Tabukan Village, Sungai Tabukan Sub-District, Hulu Sungai Utara Regency from May to November 2018. This study used a single randomized block design (RBD). The factors studied were various doses of water hyacinth bokashi consisting of 4 levels of treatment, namely e0 = 0 kg, e1 = 1 kg, e2 = 2 kg and e3 = 3 kg. The results showed that the addition of water hyacinth bokashi had an effect on the vegetative performance of plants on plant height and number of leaves, not affecting the stem diameter. The e3 treatment (3 kg) is the best dose for the vegetative period of alabio’s yams. As for the generative performance, the addition of water hyacinth bokashi has no effect.

Penelitian ini dilaksanakan di Kabupaten Jembrana, dengan tujuan untuk menganalisis kerusakan lingkungan biotic di wilayah pesisir Kabupaten Jembrana, dan menganalisis kerusakan lingkungan abiotik di wilayah pesisir Kabupaten Jembrana. Metode yang digunakan dalam penelitian ini adalah wawancara, observasi dan pencatatan dokumen. Pengambilan sampel dengan menggunakan teknik purposive. Penelitian ini merupakan penelitian deskriptif dengan analisis data kualitatif. Hasil penelitian menunjukan bahwa terdapat kerusakan lingkungan biotik berupa abrasi pantai, dimana yang tertinggi terjadi di Kecamatan Melaya mencapai luas 7,45 km, sedangkan terendah terdapat pada Kecamatan Mendoyo yang hanya mencapai 2,66 km. Terdapat kerusakan lingkungan abiotik berupa pencemaran oleh industri, peternakan dan sampah plastik.

Cultivation of peanut plants in lebak wetlands is constrained by inundated land and the fertility of varied soil, from fertile to nutrient-poor levels. Poor soil nutrients can not only be overcome by fertilizing, for example with manure chicken manure. The availability of nutrients in the land can be improved by providing ameliorats such as rice husk ash. This study aims to determine the effect of (i) the interaction of chicken manure manure and rice husk ash, (ii) the single factor of chicken manure manure, (iii) the single factor of rice husk ash, (iv) getting the best dose of chicken manure manure, ( v) the best dose of rice husk ash and (vi) the best interaction of manure chicken manure and rice husk ash on lebak wetland. The study was conducted in the village of Teluk Betung, Sungai Pandan Subdistrict, HSU Regency in February - May 2019. It was using a factorial Randomized Block Design (RBD) with two treatment factors. The first factor: the dose of chicken manure, consisting of 3 levels, namely a1 = 12 tons. ha-1, a2 = 16 tons. ha-1, a3 = 20 tons. ha-1. The second factor: the dose of rice husk ash, consisting of 3 levels, namely s1 = 24 tons.ha-1, s2 = 28 tons.ha-1, s3 = 32 tons.ha-1. The results showed that the interaction between chicken manure had no effect on growth and yield, the single factor of chicken manure had an effect on growth and yield but had no effect on the number of leaves, and the single factor of rice husk ash did not affect growth and yield but had an effect on age flowering.

Along with the increasing demand for palm oil has the world's population, it is necessary to think about efforts to increase the quality and quantity of palm oil production. One of the factors such as planting material in the form of seeds, it is necessary to act technical culture or good seed treatment. Oil palm seedlings can be done in two stages: initial seeding (prenursery) and moved at the age of 2.5-3 months when they fulfill the criteria nursery ready to move to the main (main nursery). This study aims to (i) determine the speed of growth of oil palm seeds and, (ii) obtain the best type of soil for growing speed of oil palm seeds in two places making swampy marshland. The research was conducted in the Pangkalan Sari Village, Sungai Pandan Sub-district, Hulu Sungai Utara Regency in July-August 2013, using a completely randomized design (CRD) with a single factor. Factors studied were two lebak wetland of origin of uptake (T) as much as two levels and repeated nine times. The results showed that the two treatments had no effect lebak wetlands on many shoots observation variables age 14 and 28 days after seeding(DAS), the amount of leafage of 14 DAS, seedling height 14 DAS, and significant observations on many variables shoots the age of 42 DAS, number of leaves age 28 and 42 DAS, and a very significant effect on seedling height observation variables age 28 and 42 DAS.
