The vertical gradiometric survey was done by the Geometrics-G-858 Cesium magnetometer. The gradiometric results showed three clear longitudinal magnetic anomalies in different places on the magnetic contour map. The main anomaly is located on the edge of the northern part of the study area and extends longitudinally in the northwest and southeast direction. This may indicate the presence of the main outer wall, as it extends lengthwise about 30 m, with a width of 3-4 m, and a depth of about 1 m below the surface of the ground, and may contain the main northern gate of the Dilbat Temple. Besides that, this anomaly displayed approximately a high magnetic value of about + 60 nT, which indicates that the wall was built from baked brick composed of clay minerals rich in iron oxides. Furthermore, the magnetic contour map showed two other magnetic anomalies. The first one is located in the western part of the study area and appears perpendicular to the main magnetic anomaly. Meanwhile, the second anomaly occupied the southern part of the study area and is parallel to the main anomaly. The two anomalies showed approximately lower magnetic strength than the outer wall. So, they may represent the remains of the inner room walls built from mud bricks. The thickness of the two supposed walls is about 2.5 m and they are at a depth one meter from the ground. The findings of this method have been a good guide for new excavation, which led to finding the main wall built from fired bricks.

The typical symptom that is caused is in the form of twisting leaves so that this disease is known as Moler disease. The most frequently used control is by using chemical pesticides. Paying attention to the negative impact of chemical pesticides in the form of environmental damage and threat to the health of non-target living things, one solution is to use environmentally friendly and safer vegetable pesticides such as using durian fruit skin. Durian rind has been confirmed to contain compounds that have anti-fungal properties. Therefore, this study was conducted to determine the potential of durian peel in powder form as a vegetable pesticide to control F. oxysporum disease in shallot plants. The research was conducted in 2 stages, namely in vitro and in vivo. The research method carried out in vivo was a randomized block design (RBD) with 5 treatments (negative control (F. oxysporum inoculation), positive control (F. oxysporum + fungicide (Benomil), durian peel powder 0.125 kg/ha + F. oxysporum, Durian peel powder 0.25 kg/ha + F. oxysporum, durian peel powder 0.375 kg/ha + F. oxysporum) and 4 replications. in vitro or in vivo.

So far, efforts to control that are safe for humans and effective to inhibit the reproduction of rice lice are still being pursued. One of them is by using vegetable pesticides, therefore it is necessary to carry out safe controls for humans, one of which is the use of vegetable pesticides. This study aims to determine the effectiveness of red betel leaf powder (Piper crocatum) on the mortality of rice lice (S. oryzae). This study used a completely randomized design (CRD) with 5 one-factor treatments with 4 replications. The parameters observed were mortality of rice lice, efficacy of red betel leaf powder and percentage of damage to rice. The results showed that the treatment of red betel leaf powder with various doses was able to suppress the S. oryzae population but the red betel leaf powder could not be said to be effective, because based on the calculation of the formula of abbot (1925) the highest average mortality was only 47.50%, while mortality rice lice must be up to 70% to be effective. The lowest percentage of damage to rice was found in treatment with a dose of 2.5 grams, namely 0.18%. Some of the rice that was damaged by S. oryzae became powder and some were still intact in the form of rice but had many holes due to S. oryzae attacks.

Since it has large agricultural land, most of the livelihoods of the residents are farmers. Two major obstacles of the agriculture in this area are the land that needs fertilizer and the land sometimes flooded during the rainy season. The most effective way to solved the problems is the manufacture of organic fertilizer by utilizing indigenous microbes and water weeds as the main ingredients and the flooding itself needs government assistance to build ponds besides agriculture by utilizing yards according to the principles of urban farming. Those activities will begin with an approach to the Cempaka District Government and Bangkal Village to get an initial picture of agricultural conditions. The second stage was holding counseling meetings which involved the Cempaka sub-district head, Bangkal village head, and the head of the existing farmer group along with several members with the number of participants up to 42 people. The analysis of the questionnaire shown that farmers still need direct practice on how to make fertilizer with team assistance from the start such as looking for the isolate and processing water weeds into fertilizer. The results of isolation on the farmer's land found Trichoderma sp and water weeds of the Kalakai and Kayapu types which can be used as materials for propagating organic pesticides. Assistance on the land continued so that the Paddy Flower Farmers' group belonging to one of the farmer groups succeeded in making prepackaged fertilizer that has been ready to be marketed besides being used by members of the group and local farmers. This is a big hope for us. Altogether with the assistance of the sustainability team, Bangkal landspecific organic red rice products will be ready for market.

One of the common pests of chili was aphid that did not only damage the crop, but also was the virus disease vector, so that the chili plant faced crop failure or had low productivity. This research aimed to find out the effect of garlic solution application on the intensity of aphid attack on chili plant. This research was being conducted during 5 months (February-June 2019). The research result showed that the use of garlic solution had effect on the attack intensity, but had no effect on the number of aphid population. It was because the garlic solution was an antivirus which could inactivate the virus that was carried by the aphid.
