Effect of sago waste, manure and straw biochar on peanut (Arachis hypogaea L.) growth and yield on an Ultisol of Southeast Sulawesi E Tando; A Nugroho; T Islami

Farmland in Southeast Sulawesi is largely dominated by Red and Yellow Podzolic soil type or Ultisol up to 60.30% of total soil. Aspects that caused low productivity, deteriorating soil physically and chemical properties in Ultisol soil is low soil organic matter content. Average peanut production in Southeast Sulawesi 2014 reached 0.46 t, on the other hand average domestic production is 1.87 t. The decrease in production is caused by decline in land productivity. Low peanut production is caused by soil fertility. Declining soil fertility can be restored by applying organic matter into the soil, but, in a tropical environment, the rate of organic matter decomposition and mineralization take place very quickly, resulting in additional organic material each planting season. Another alternative is to reduce the organic matter decomposition rate and release carbon in the soil through utilizing agricultural and animal waste into biochar which is resistant to corrosion. The experiment was conducted using a randomized block design which consisted of nine treatments and three replications. The results exhibited that straw biochar at 25%, or 2.48 t/ha + manure biochar at 75% equivalent to 5.87 t/ha was capable of increasing growth and yield rate for peanut varieties Talam 1 . Peanut varieties Talam 1 yield increased after sago waste , manure and straw application, by 45.62% compared to peanut crops yield without utilizing biochar on Ultisol.

The Indonesian government begins to promote food diversification program. The government expects the Indonesian people can consume food crops other than rice, such as wheat, potatoes and sweet potatoes. While, the level of production of sweet potato production decreased in the period of 2012-2015 with total production of only 2,218,992 t/ha. In an effort to increase the production of sweet potato, improvements are needed through application of organic fertilizers like composts. The purpose of this study was to explore the effect of composted manure with ground fish bone, legume residues, and Tithonia on soil chemical properties and sweet potato production includes tuber weight and levels of starch sweet potato crops.The results showedthat application of 5 t compost/ha and 35 kg Trichoderma biofertilizer/ha increased pH, water content, organic carbon, total N, available P, total Kl, CEC,exchangeable Ca, plant height, tuber weight and levels of sweet potato starc

Pandansari village, Ngantang District was severely affected by Mt. Kelud eruption in 2014. Almost all soil surfaces were covered by the eruption product, leading to serious problems for cultivation. Pyroclastic materials potentially have high content of nutrients, but they are not readily available to plants. As an attempt to improve chemical properties of the pyroclastic materials, we applied locally available organic matters, from four different sources, i.e. leaves of sweet potatoes, Tithonia diversifolia, maize, and cow manure. The pyroclastic materials were sieved at 2 mm, placed inside pots (50 x 50 x 50 cm3), until it reached 30 cm thick. The fresh leaves were chopped into 2 mm size and mixed with the pyroclastic materials at the dosage of 15 Mg/ha. They were incubated and kept at field condition. Selected chemical properties (pH, CEC, sum of basic cations, and the total contents of N, organic C, and available P) were measured before and after 90 days incubation. The results showed that after 90 days, organic matter application significantly increased pH, cation exchange capacity, organic C, and total exchangeable basic cations content. The increases of P-available and total N contents were only detected on cow manure treated materials.

Fusarium wilt caused by F. oxysporum f.sp. cubense is one of very damaging banana plant diseases which can cause plant death. Disease control using intensive chemical fungicides will have negative impacts on the environment and humans. Endophytic Trichoderma is one of the biological control agents which can reduce the amount of inoculum of pathogens, so it can reduce disease intensity. The objectives of this study was to assess the ability of endophytic Trichoderma in inducing plant resistance against fusarium wilt. Endophytic Trichoderma was obtained from healthy roots of banana from three regencies in Yogyakarta, namely Trichoderma harzianum.swn-1, T. harzianum.swn-2, T. harzianum.psr-1, T. asperrellum, T. gamsii, and T. koningiopsis. Research on induced resintance was conducted in the greenhouse with polybag using Completely Randomized Design with 14 treatments and 3 replications. The results showed that the ability of Trichoderma gamsii antagonism against F. oxysporum f.sp. cubense was 60.61%. T. asperellum and T. harzianum.swn-2 could suppress this disease resulted in disease intensity of 8.33% which categorize as resistant. Trichoderma harzianum.psr-1 was significantly different in stimulating plant vegetative growth. Induced resistance by using endophytic Trichoderma spp. against F. oxysporum f.sp. cubense showed increase in total phenolic compounds on the third and fourth weeks as well as peroxidase activity on the third, fourth and fifth weeks. Observation of lignification on the fifth week showed that lignification occurred in root xylem

The economic activities analysis of the marginal community living around the artisanal oil mining site in Hargomulyo, Bojonegoro Regency N T Brata; S Sairin; S Setiadi

Publisher : Brawijaya University

The focus of this paper is on a marginal society in Bojonegoro Regency, East Java Province. It is a remote area in the middle of a teak forest, far away from the centre of economy and governance, it’s that makes the society find some difficulties to overcome their economic problems. There are some oil wells owned by NV BPM Company which had stopped its legal operations. Then, the society conducts illegal traditional oil mining. The purposes of this study are: (1) to study the reason of the society in making the artisanal oil mining as their livelihood, (2) to study the economic implication from their mining activities. The results showed that in a tough life to fulfil their needs, there is a creative idea from the society in seeing and understanding their infertile environment. In an environment that looks unable to provide a chance to the society for getting a livelihood, there are some people find a niche in the form of old oil wells. The society is able to find an environment niche to resolve their poverty problems. The economic implication is in the form of chance or entrance for the society to work in Artisanal Oil Mining (AOM) field.

Emerging development on the coastal region can result in coastal erosion and mangrove ecosystems damage. This disastercould eliminate settlements, agricultural land and public infrastructure. However, for mitigation of those events happened, the government has been constructing the Breakwaters andmangrove reforestation. We used survey method using quota sampling technique in 90 households. The study used a region-based approach. Measurement of socio-economic characteristics, knowledge, perception, and public participation were Chi square test and F test One-Way ANOVA. The results showed that most of samples were middle-lower socio-economy conditions (88.7%). The lower socio-economic caused of 1) the loss of residential and agricultural land due to beach erosion; 2) types of agricultural commodities; 3) work as farmers have the certainty get higher income than as fishermen; and 4) the ability of adaptation in the new location. The high public perception was not accompanied by high levels of public participation to rehabilitate coastal ecosystems
