Water Stress Influence For Tomato (Solanum Lycopersicum) Production
Authors: Rusnam Rusnam , Surya Ridho Adi , Makky Muhammad
Published: April 2021

Tomato, also known as Solanum lycopersicum, is one of the horticultural commodities that have a good priority to be developed. Tomato production in Indonesia has decreased over five decades. This lack of production is caused by the limitation of water supply during the dry season as to effect of its rooting. One of the ways of ensuring water supply is using an irrigation system, including drip irrigation. The use of drip irrigation will save a lot of water, but the allocation of water to be given will cause to salinity. This phenomenon requires actions to control the water for tomato production. Research in this area is being carried out in the subdistrict of Lubuk Kilangan, Padang City. The current study observes the effect of salinity on the amount of leaf, the productivity, and the sweetness of the tomato fruit. Based on the results, the efficiency of drip irrigation is around 96.28%, and there is no real effect of salinity on the amount of leaf. Additionally, salinity does not affect productivity. The highest productivity is on the treatment of giving water at -15%, amounting to 2.30 kg, and the lowest is at -5%, amounting to 1.72%. Salinity increases the sweetness of tomato, and the highest sweetness level is on the treatment of giving water at -20%, amounting to 5.6600 Brix, and the lowest sweetness level is at the control treatment, amounting to 5.1100 Brix.

O presente artigo tem o objetivo de analisar o poder que a mídia tem, interferindo no curso de processos criminais. A questão a ser enfrentada é a espetacularização irresponsável e a propagação de notícias que influenciam o pensamento do público, e que muitas vezes desrespeitam regras e princípios penais e processuais, em especial os previstos constitucionalmente. Tal situação tem por consequência uma sociedade do espetáculo, onde não se controla a influência e a manipulação dos pensamentos. É preciso considerar o papel garantista do processo penal e a proteção dos direitos fundamentais, como a dignidade da pessoa humana, por exemplo, para que eventual condenação seja resultado de um processo justo e não pela manipulação midiática. Para a presente pesquisa foi utilizada revisão bibliográfica.
The Custom Total Contact Cast to Offload Foot Ulcers in the Presence of Biomechanical Deformities: A Case Report
Authors: Khan Mohammad , Stoupine Anna , Farha Kamal , Kim Ji , Klinoubol Poovasit
Published: April 2021

BACKGROUND: Although offloading foot ulcers with a total contact cast (TCC) remains the cornerstone of managing these wounds, the TCC is underutilized. Patient intolerance and potential iatrogenic complications due to TCCs’ general lack of customizability and the inability to address flexible biomechanical deformities that are not in the sagittal plane may be one of the reasons patients with foot ulcers do not receive this crucial component of care. PURPOSE: To describe the use of a novel approach to the standard TCC technique that uses strategic padding to potentially increase patient compliance and comfort while decreasing the likelihood of iatrogenic ulceration, as well as to correct flexible frontal plane biomechanical deformities with casting tape that is pulled medial to lateral, or lateral to medial, to bring the plantar surface of the foot to neutral position. METHODS: The custom total contact cast (C-TCC) was used in a 54-year-old woman who had diabetes, obesity, and a flexible cavovarus foot type with a recurring plantar fifth metatarsal base wound. Weekly debridement followed by silver dressings and C-TCC application were performed. The latter included strategic padding, 2 forms of plaster of paris with contouring, fiberglass, and medial-to-lateral positioning of the foot during application. RESULTS: This case study describes two (2) treatment episodes, with a focus on the second episode. At initial presentation, the ulcer took 5 weeks to heal. During the second treatment, a 48.7% reduction in wound volume was noted after 1 week. By the fourth week of treatment, a 98.7% wound volume reduction was achieved. By the ninth week, the ulcer epithelialized completely. At 1-month and 12-month follow-ups, the site remained fully epithelialized. No iatrogenic ulcerations, cast discomfort, or ambulatory dysfunction were reported by the patient. CONCLUSION: In this case, the C-TCC helped address flexible frontal plane deformities and facilitated healing. Randomized, controlled clinical studies to evaluate the safety and effectiveness of different TCC methods are needed to guide care and improve the utilization of optimal offloading methods for the management of plantar foot ulcers.

Arboreal ants are ants that do activities and spend their lives in tree. Roles of this organism are to serve as decomposers, pollinators, predators and indicators. Ant species diversity constitutes a chain for ecosystem stability. They are responsible as decomposing insects making their presence becomes ecologically vital. Research on ant species diversity in mangrove forest remains insufficient. One of the reasons possibly is that fact that mangrove is an ecosystem which is affected by sea tide. This research aims at gathering data about ant species diversity based on types of mangrove forest vegetation located in Setapuk Besar, Singkawang City. The research used a survey method by observing types of trees whose diameter was 10 cm and above. Additionally, the tree should have a large number of ants. The data was collected through fly sheet trap set under, in the mid, and above the tidal level. Findings revealed 6 types of ants consisting 4 sub-families in 6 types of the trees i.e. Rhizopora mucronata, Avicennia lanata, Hibiscus tiliaceus, Terminalia capatta, Nypa fruticans, and Bruguiera cylindrical.. Based on the diversity index of those 6 types of trees, the divercity of arboreal ants spesies could be categorized low (H’<1). The highest diversity was nypa fruticans vegetation by 0.325. This was because the tree contains sugar level and carbohydrate. The lowest diversity was Hibiscus tiliaceus and Termialia catappa. The H’ value was 0. One of the reasons was because only one species of ants can be found in both trees, namely Oecophylla smaragdina.Keywords: Arboreal Ants, Diversity, Mangrove, Singkawang

Rubber is a forestry plant producing sap. Rubber latex is needed for various industrial purposes. Rubber is a side business as well as additional income for the community besides farming in Banua Tengah Village. The method used is a survey method with interview techniques. Sampling was done intentionally (purposive sampling). The number of samples taken was 61 respondents who were ; rubber farmers, married, worked tapping rubber and owning rubber plantations. Data analysis consists of calculating total income and multiple linear regression analysis. The analysis results obtained total income / Tr received by farmers around Rp. 390,000 - Rp. 2,840,500 / month, when compared to the UMR established by the Government in 2018, UMR Kapuas Hulu Regency is Rp. 2,204,650.00 / month, there are 2 (two) farmers who have an income above the minimum wage while 59 other farmers are still under the UMR There are four factors that influence the income of rubber farmers in Desa Banua Tengah namely land area, work experience, rubber age and workdays, of the four most influential factors are land area and workday variables, while the work experience and rubber age variables are not very influential. Factors of land area, work experience, rubber age and working days together greatly affect farmers' incomes with the equation of total income of rubber farmers as follows: ln Y =  9,817 +  0,397 ln X1 + 0,098 ln X2 + 0,061 ln X3 + 1,194 ln X4 Correlation value R = 0.928 and the value of determination R2 = 0.861 From these equations obtained a constant value of 9,817 which shows that income from rubber farmers (Ŷ) in Desa Banua Tengah is Rp. 9,817 if X₁, X₂, X3 and X4 are considered zero. Ŷ is positively correlated with X₁, X₂, X3 and X4.Keywords: Influential factors, Latex, Rubber farmers, Total income

In general, the fertility rate of ex-mining tailings sand is very low, so plants to restore it must be fertilized with the right type and dosage. One type of plant that can be used for ex-mining land (tailings) is the Ketapang plant (Terminalia catappa L). The research objectives determine (1) the effect of the use of chicken manure fertilizer and urea dose on the growth of ketapang seedlings in the nursery and (2) the composition of chicken manure fertilizer with tailings and the dose of urea fertilizer for the growth of ketapang seedlings in the nursery. This research was carried out in Ketapang City by factorial completely randomized factorial design (RAL) method. The experimental treatment consisted of giving chicken manure and urea fertilizer to the tailings media. The first factor is chicken manure (T) tailing media without sand chicken manure (T0), 1: 1 (T1), 1: 2 (T2), and 1: 3 (T3). The second factor is the addition of urea fertilizer with a dose of 0 grams (P0), 0.5 g (P1), 1.0 g (P2), 1.5 (P3), and 2 g (P4). Each treatment combination was repeated 3 times so that in the experiment as many as 60 seeds were used. Data collected in the form of seedling height (cm), base diameter (mm), number of leaves (strands), and dry weight of seeds (g). The results showed that the treatment of chicken manure and urea fertilizer on ketapang seedlings on the tailings sand media in the nursery significantly affected the diameter and biomass growth (dry weight) of ketapang plant seeds (T. catappa L). The use of chicken manure fertilizer without urea fertilizer could increase height growth and the number of leaves. The composition by comparing one part of tailings sand with one, two, and three parts of chicken manure does not show a significantly different effect. This means that for the nursery of ketapang plants, it is sufficient to use the composition of one part tailing sand and one part chicken manure. Giving urea fertilizer without chicken manure has not been able to improve the growth of ketapang seedlings (T. catappa L).Keywords: chicken manure, ketapang plants, tailings Sand, urea fertilizer
