ANALISIS YURIDIS PUTUSAN PENGADILAN NEGERI KABUPATEN TULUNGAGUNG NOMOR REGISTER 18 / Pdt.G / 2018 / PN TLG TENTANG SENGKETA HAK ATAS TANAH EKS HAK EIGENDOM YANG BELUM DIKONVERSI

An issue involving a civil rights council against the Bolorejo village government in the court of tulungagung district registration number 18/Pdt.G/2018/PN TLG is an example of an unlawful act perpetrated by the Bolorejo village government. This is because the government of the Bolorejo village wants to take control and use the mountain bolo hill area located in Bolorejo village, by Kauman district, tulunggreat district, as a tourist resort, which can provide an interest and icon for Bolorejo village. But the goal of developing the tourist area has been deemed illegal due to the use of the mountain bolo hill area which is a legitimate burial site on behalf of a true community. The status of the land in the foothill of mount bolo still as eigendom vorponding, is the reason government of the Bolorejo village used the cemetery as a tourist resort without first applying permission to the established peace association and holding the rights of the former western right since 1912

Seed Quality of Greengram Stored in Different Storage Environment

A laboratory experiment was conducted with mungbean seeds kept in three different containers. Three containers were tin pot, poly bag and jute bag and stored at room temperature and RH for three months (23 June-23 September) in the Laboratory of Agronomy Department, Sher-e- Bangla Agricultural University, Dhaka, Bangladesh to study their storage behavior, germination percentage and quality. The seed of jute bag came to the contact with air and their moisture contents was decreased from initial moisture content and remained near to their Equilibrium Moisture content (EMC), moisture content of the seeds of jute bag was found decreased from 7.50% to 16.70% within 6 weeks of storage. But moisture contents of seeds of tin pot and poly bag remained approximate constant throughout 7 weeks period. As tin pot and poly bag was more or less air tight so the seeds of these container could not come to the contact with ambient room air, resulting no significant change of their moisture content. Germination capacity of the seeds of tin pot was found decreased from 78% to 68% and 77% to 58% in the seeds of poly bag. Germination capacity of the seeds of jute bag was found decreased from 73% to 48%t in 5th week of storage. So, the germination capacity was also found a little bit higher than the seeds of other containers. Considering three different container, tin pot container has been proved much more safe and secured than jute bag or poly bag container

RANKL/RANK/OPG Pathway: A Mechanism Involved in Exercise-Induced Bone Remodeling

Bones as an alive organ consist of about 70 mineral and 30 organic component. About 200 million people are suffering from osteopenia and osteoporosis around the world. There are multiple ways of protecting bone from endogenous and exogenous risk factors. Planned physical activity is another useful way for protecting bone health. It has been investigated that arranged exercise would effectively regulate bone metabolism. Until now, a number of systems have discovered how exercise could help bone health. Previous studies reported different mechanisms of the effect of exercise on bone health by modulation of bone remodeling. However, the regulation of RANKL/RANK/OPG pathway in exercise and physical performance as one of the most important remodeling systems is not considered comprehensive in previous evidence. Therefore, the aim of this review is to clarify exercise influence on bone modeling and remodeling, with a concentration on its role in regulating RANKL/RANK/OPG pathway. © 2020 Mohammad Tobeiha et al

Research was arranged by randomized block design, fourtreatments and six replications. Treatments consist of (1) farmerstechnology, i.e. distilled water of basil (Ocimum spp.), (2) farmerstechnology, i.e. essential oil of basil (Ocimum spp.), (3) essential oil ofbasil formulated in IMACRI and (4) commercial attractant. Each formulawas dropped as much as 0.25 ml on cotton bud, except distilled water ofbasil which is applied by dipping the cotton bud into the distilled water,placing it in the trap made from 600 ml volume drinking water, thenhanging it as high as 2 m on the mango tree. Dropping of formula wasdone just one time to evaluate the duration of attractant on trapping fruitflies in the field. Observations were done every week on the number,species, sex ratio of fruit flies trapped, and the duration of attractant abilityon trapping fruit flies in the field. The active ingredient of formula wasanalyzed by Gas Chromatograph conducted in IMACRI. The social andeconomy aspects were done by interviewing the farmers throughquestionnaires. The number of the farmers interviewed were 30 farmers,including the trader of mango. Result showed that indigenous technologyof the farmer was effective and efficient since it can decrease the use ofpesticide as much as 62% and decrease fruit damage as much as 34% andincrease their income as much as 73%. Technology of farmers in the formof distilled water of basil could stand as long as a week on trapping fruitflies, hence its application must be repeated every week. Meanwhile in theform of essential oil could stand for one month and is not significantlydifferent with attractant formulated in IMACRI, even better thancommercial attractant, hence its application can be done every month.Only male fruit flies can be trapped and most of them consist ofBactrocera dorsalis species (97%) and the rest is Bactrocera umbrosusspecies (3%). The active ingredient content (Methyl eugenol – C 12  H 24 O 2 )in the distilled water of basil is 0.43%. Meanwhile in essential oil of thefarmer is 77.9% and in essential oil of IMACRI is 73.6% and incommercial attractant is 75%.Key words : Ocimum minimum, Bactrocera dorsalis, Mangifera indic

Effect of mulching and organic manure on growth and yield performance of wheat

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh in Rabi season (dry season) of 2014 to study the effect of mulching and organic manure on growth and yield performance of wheat. Five mulching practices viz. M1=1 irrigation at 17-21 days after sowing (DAS), M2=2 irrigations at 17-21 and 55-60 DAS, M3=3 irrigations at 17-21, 55-60 and 75-80 DAS, M4=control, M5=straw mulch (6 t ha-1) and five organic manure managements viz. O1=recommended chemical fertilizer (NPKS @ 100-23-20-16 kg ha-1), O2=poultry manure @ 6 t ha-1 (100% PM), O3=vermicompost @ 8 t ha-1 (100% VC), O4=50% chemical fertilizer+50% VC and O5=50% chemical fertilizer+50% PM were used as experimental variables. The experiment was conducted in split-plot design with three replications. The results showed that mulching had significant influence on all attributes. The highest values of all attributes were found in straw mulch treatment. It was observed that organic manure had significant influences on all characters. The highest values of yield and yield attributes were found in O5 (50% chemical fertilizer+50% PM) treatment. It was observed that effective tillers hill-1, grain yield and straw yield were significantly affected by combined effect of mulching and organic manure. The highest values obtained from mulching and O5 (50% chemical fertilizer+50% PM) treatment. Therefore, it can be inferred from the results of the study that highest production could be obtained from mulching and O5 (50% chemical fertilizer+50% PM) treatment
