Pratylenchus brachyurus is a major parasitic nematode on patchouli that reduces plant production up to 85%. The use of endophytic bacteria is promising for controlling nematode and promoting plant growth through production of phytohormones and enhancing the availability of soil nutrients. The objective of the study was to evaluate the efficacy of endophytic bacteria to control P. brachyurus on patchouli plant and its influence on plant productions (plant fresh weight and patchouli oil). The study was conducted at Cimanggu Experimental Garden and Laboratory of the Indonesian Spice and Medicinal Crops Research Institute (ISMECRI), Bogor, West Java. The experi-ment was designed in a randomized block with seven treatments and eight replications; each replication consisted of 10 plants. The treatments evaluated were five isolates of endophytic bacteria (Achromobacter xylosoxidans TT2, Alcaligenes faecalis NJ16, Pseudomonas putida EH11, Bacillus cereus MSK and Bacillus subtilis NJ57), synthetic nematicide as a reference, and non-treated plant as a control. Four-week old patchouli plants of cv. Sidikalang were treated by soaking the roots in suspension of endophytic bacteria (109 cfu ml-1) for one hour before trans-planting to the field. At one month after planting, the plants were drenched with the bacterial suspension as much as 100 ml per plant. The results showed that applications of the endophytic bacteria could suppress the nematode populations (52.8-80%) and increased plant weight (23.62-57.48%) compared to the control. The isolate of endophytic bacterium Achromobacter xylosoxidans TT2 was the best and comparable with carbofuran.

Konsep blue carbon yang diperkenalkan oleh UNEP, FAO dan UNESCO pada tahun 2009 memasukkan padang lamun sebagai salah satu ekosistem yang mempunyai peran dalam penyerapan karbon global. Karbon yang diserap disimpan dan dialirkan dalam beberapa kompartemen, antara lain di sedimen, herbivora, kolom air, ekosistem lain dan dalam bentuk biomassa. Penelitian dilakukan di Pulau Barranglompo , Makassar, untuk melihat potensi stok karbon yang tersimpan dalam biomassa lamun. Kepadatan lamun diukur dengan melakukan sampling menggunakan metode transek kuadrat dengan ukuran 50cm x 50cm. Sedangkan untuk biomassa dilakukan dengan transek 20cm x 20cm. Hubungan antara kepadatan, biomassa dan kandungan karbon dari lamun digunakan untuk menentukan jumlah stok karbon. Kepadatan lamun disurvei pada 236 titik , sedangkan untuk pengambilan sampel biomassa dilakukan pada 30 titik. Hasil penelitian menunjukkan bahwa komunitas lamun mempunyai total stok karbon sebesar 73,86 ton dari total luas padang lamun 64,3 ha. Karbon di bawah substrat sebesar 56,55 ton (76,3%), lebih tinggi dibanding karbon di atas substrat yang hanya 17,57 ton (23,7%). Jenis lamun Enhalus acoroides menyumbang lebih dari 70% terhadap total stok karbon. Berdasarkan kelas karbon, kontribusi terbesar ditemukan pada kelas 100-200 gC . m - 2 sebesar 29,41 ton (39,7 %). Hasil ini menunjukkan bahwa ekosistem lamun berperan sangat penting dalam menjaga stok karbon di laut sehingga perlu mendapatkan perhatian untuk konservasinya. Kata kunci: konsep blue karbon, lamun, B arranglompo Blue carbon concept as introduced by UNEP, FAO and UNESCO in 2009 included seagrass beds as one ecosystem having a significant role in global carbon absorption. Absorbed carbon was stored and distributed in various compartments such as in sediments, herbivores, water column, other ecosystems and in form of biomass. The research was conducted in Barranglompo Island, Makassar City to analyze the potency of carbon stock that stored within seagrass biomass. S eagrass density was sampled using quadrat transect method with size of 50cm x 50cm . While for b iomass was done by harvesting seagrass at transect of 20cm x 20cm in root penetration depth. R elationship between density, biomass and carbon content of seagrass were used to determine t otal carbon stoc k. S eagrass density was surveyed at 236 points , while for biomass sampling was conducted in 30 points . The results showed that seagrass community had total carbon stocks as much as 73.86 tonnes from overall 64.3 ha of seagrass bed areas. Below ground carbon had 56.55 tonnes (76.3%), higher compared to that aboveground which only 17.57 tonnes (23.7%). Seagrass species Enhalus acoroides contributed more than 70% to the total carbon stocks, whereas, based on the carbon classes, the highest contribution was found at class 100-200 gC . m - 2 i.e. 29.41 tonnes (39.7%). These results suggest that seagrass ecosystem plays an important role in maintaining the carbon stock in the ocean and should receive good attention for its conservation.

The agriculture development of progressive crop land consists of three significant factors such as human resources, natural resources and appropriate technology. The method used in the research is survey, a kind of research of which data is collected from samples over population to represent all population. The type of survey used is explanatory research, a kind of research means to explain the position of variables researched and the relation between a variable and another. The population of the research was all the youths in Labuhan batu Utara being 17-30 years old. According to BPS data in 2013, there were 46,091 youths in Labuhan batu Utara. Sampling used simple sampling random method where sample taken randomly from population based on the probability frequency of all the population’s members. By using the formula of Frank Lynk, it was obtained 96 sample respondents. The conclusion of the research is 1) the youths’ perception to the agriculture development of progressive crop land in Labuhanbatu Utara is positive, 2) the youths’ role to the agriculture development of progressive crop land in Labuhanbatu Utara is positive and 3) the effect of the youths’ role as the agent of change, the agent of development and the agent of modernization is simultaneously significant to the agriculture development of progressive crop land in all the aspects- human resources, natural resources and appropriate technology. Meanwhile the variable of the agent of modernization effects positively but is not significant to the agriculture development of progressive crop land.Keyword: youth, agriculture development, food Land Sustainable

At this time character education can no longer be ignored because of the role that is very important to improve the moral and morals of children because the moral children of today's nation are getting away from the good word with the modern era of changes that are cultivated in information technology that is growing rapidly renewal. In this PKM activity, to overcome the apparent problems, the team of lecturers Prodi PAI offers PKM implementation with the form of Character Education Education as a Pillar in Building Moral And Child Morals held at PKBM Luthfillah, which is opened for PKBM and general participants. Considering many people who do not have formal education or equality, this counseling is expected to be useful and equip the community about understanding the guidance of Islam in educating children at home in general and about the procedures for the implementation of personal Islamic character education that can be maximally endeavored by each family members, both the head of the family and the representatives and all their members, so as to assist the government in socializing character education for the grass root community in practice level.
