Abstract

Silvopasture is a land management system that combines forestry components with livestock components. A study on the analysis and development of the silvopasture agroforestry system was conducted in Bangkalan Regency, Madura in September 2022. The purpose of this study is to identify the components in silvopasture and the interactions between its components. In addition, identifying the role of silvopasture based on production and protection functions for agroforestry development is then made. The research was conducted in three stages: secondary data collection, field survey for primary data collection, and presentation of research results. The results showed that silvopasture was applied using a random mixture planting pattern that was grown in a monoculture. This agroforestry system combines the cultivation of teak, cattle, and chickens, and weeds under teak stands. The silvopasture has a role in improving soil fertility, reducing nutrient loss, increasing N availability, maintaining soil physical properties, reducing erosion hazards, creating a microclimate, reducing weed populations, and protection against plant disease pests. The development plan is prepared by taking into account the principles of productivity, sustainability, and adaptability (according to local conditions).

Abstract

Walang sangit is one of the potential pests which at certain times becomes an important pest. These pests can cause yield losses of up to 50%. It is estimated that a population of 100,000 heads per hectare can reduce yields by up to 25%. This research on the intensity of the pest attack was aimed at knowing the categories of attacks on land owned by farmers in Karangnangka Village and finding out more environmentally friendly control methods. The number of plants observed every week was selected as many as 30 points (clumps) marked by pieces of bamboo or wood with a diagonal pattern. Data collection started by counting the number of plants in one clump at each sample point, then continued by counting the number of grains in each clump, and the last data was the number of seeds that were attacked or damaged in each clump. Then increase the attack intensity calculated using the absolute attack intensity formula. Calculations show a decrease every week, with values ??of 4.84%, 5.99%, and 6.60% sorted from the first observation to the third week. The control that can be applied is the use of animals (crabs) as traps to attract pests such as stink bugs.

Abstract

Chili (Capsicum annum) is one of the horticultural commodities that has an important role in human life and Indonesian chili plants have important economic value and occupy second place after beans. Meanwhile, in East Java, chili commodity production in 2013-2017 reached 440 tons and one of the highest contributors was Ringinsari, Kandat, Kediri. However, the increase in chili commodities in the village has so far been strongly influenced by the presence of the fungi pathogen is Fusarium oxysporum f.sp.capsici that cause wilt disease, can reduce production on average up to 75 % and cause the plant to die. The control of that pathogen generally uses chemical control that hurts humans and the environment so until now it have not been satisfactory. Depend of that it needs alternative control using endophytic bacteria that are formulated in organic fertilizer as biological control. Endophytic bacteria are group of bacteria that live in plant tissues without causing negative effects, including not causing plants to get sick and having a mutual relationship with their host plants. Endophytic bacteria can be found in various plants including agricultural crops and can be isolated from all parts of the plant, namely roots, stems, leaves, and seeds. Endophytic bacteria produce secondary metabolites and compounds that can be used to induce plant health and growth. Endophytic bacteria produce fenol, flavonoid that increase plant resistance to diseases and pests, improve plant health, phytohormones increase plant growth. The method stages of research are propagation of endophytic bacteria, manufacture of suspension of endophytic bacteria, mixing of suspension of endophytic bacteria into organic fertilizer, data analysis using analysis of variance and 5% BNT test. The results are Incubation period is slower, disease intensity decreases, and plant height increases.

Abstract

This extraordinary peatland area can have various impacts, especially in Indonesia and even globally. In general, in soil classification, peat soil is known as Histosol. Based on the maturity level, there are safric, fabric, and hemic maturity levels. In general, peat soils have a relatively high level of acidity with a pH range of 3-4. Peatland management in the Central Kalimantan region has developed quite rapidly where many peatlands can be used as agricultural lands, such as in the Kalampangan area. Several types of land use analyzed in this study are dragon fruit monoculture, agroforestry with chili as the main crop, burnt forest, and natural peat forest. The analysis was carried out to determine the pH and available P content in the peat soil on each land use. The pH range in each land use is acidic with the highest actual pH range of 4 in the dragon fruit monoculture land use and the lowest in the natural forest landuse of 3,2. Meanwhile, the potential pH has a fairly similar value in the range of 2.1 to 2.5. The highest available P was obtained in chili agroforestry and the lowest was in the burnt forest. The highest available P was obtained in chili agroforestry and the lowest was in the burnt forest. The available pH and p values are strongly influenced by the management carried out by farmers, whereas in some areas the management is carried out quite intensively. An inventory of peat characteristics data is needed for current and future land development.

Abstract

Rubber (Hevea brasiliensis Muell Arg.) is one of the main commodities in the plantation sector in Indonesia, making demand for rubber increases every year. The higher the demand for natural rubber, the higher the level of rubber production. Rubber productivity can be maximized through the application of exploitation systems in the field. The exploitation system is a series of tapping systems that are applied throughout the production time of rubber plants (20-25 years) with the aim of obtaining high production yields, and are divided into 2, namely conventional exploitation and stimulants. The application of an excessive rubber exploitation system can cause Tapping Panel Dryness (KAS) disease which is characterized by not releasing latex or drying latex. This research was carried out on January 10 – February 12, 2022 at PT Perkebunan Nusantara XII Kebun Kotta Blater, Jember Regency which aims to determine the effect of the exploitation system on KAS. KAS is influenced by all stages in the exploitation system such as the use of stimulants, plant age, and tapping techniques. The intensity of KAS disease in old rubber TM in 1995 and 1996 was 1-2,20%, while in young rubber TM in 2013 it was 0%. The older the age of the rubber plant, the more susceptible it is to CAS disease as a result of tapping with high intensity (over exploitation), excessive stimulants, or tapping techniques that are not in accordance with the norm, causing wood injuries.

Abstract

This paper aims to examine the role of in vitro culture as a technique to produce secondary metabolites that are needed in various fields. In addition to producing secondary metabolites, in vitro culture can also be used as a plant conservation technique that can produce plantlet asexually in large numbers. This large number of plantlets besides being commercialized, its growth and development of plants is useful for overcoming the decline in environmental quality. An example of a plant will be useful as the lungs of an area and its roots will reduce the erosion of land areas. The conceptual framework of this study is that in addition to producing secondary metabolites, in vitro culture also has a function for plant conservation which in the future can prevent environmental damage. The problem in this study is the instability in the secondary metabolite biomass production and the need for optimization in the domain of conservation techniques. The method of this paper writing was extracting data information from journals, books and online sources which being analysed descriptively and qualitatively to verify the data objectively. The result of this study showed the role of in vitro culture that can produce secondary metabolites and can be implemented in plant conservation that overcome environmental crises.

Abstract

Dragon fruit (Hylocereus sp.) has problems in its cultivation related to Plant Pest Organisms (OPT). One of the pathogens that attack dragon fruit plants is Colletotrichum sp. which can cause anthracnose. dragon fruit pest control method can be done by using biological pesticides from neem leaf extract. Pesticides from plant extracts are sources of various compounds that are rich in various types of active ingredients such as secondary metabolites that play an important role in the process of interacting or competing and protecting themselves from competitors. The purpose of this study was to determine the effectiveness of neem leaf pesticide for controlling anthracnose on dragon fruit plants. The method used is testing the inhibitory power of neem leaf biological pesticides against anthracnose on dragon fruit plants in vitro. The concentration treatments of biological pesticides included 0%, 20%, 40%, and 60%. The results obtained showed that the biological pesticide neem leaf with a concentration of 20% already had an inhibitory power against the pathogen Colletotrichum sp. which is quite good because at that concentration it already has a fairly high antifungal compound. The magnitude of the inhibitory power of neem leaf biological pesticides at a concentration of 20% was 53.94%.

Abstract

The increase in human population causes several negative impacts, one of which is the extreme climatic changes. The main cause of this climatic changes is global warming due to the increase in greenhouse gases (GHG) such as CH4, CO2, and NO2 in the atmosphere where this is caused by the burning of fuel for motor vehicles and factories, as well as a decrease in carbon-absorbing plant vegetation due to the clearing of new land. This research is to estimate how much coffe plantation in ATP Jatikerto contribute on containing carbon stock. The methods used in this study namely non destructive by adhering to SNI-7724 which recommends estimating carbon stocks using an allometric model, the types of plants at the observation site were Coffea liberica, Coffea canephora, Gliricidia sp., Leuceana sp., Musa sp., and Theobroma cacao. There are 4 vegetation structures at the observation site, namely C. liberica with Gliricidia sp., then C. canephora with Gliricidia sp., then C. canephora with Leuceana sp., and C. canephora with Musa sp.
