Terrestrial arthropods were trapped with pitfalls where installed on two lakeside at nine different sampling site and two sampling date, April (before flooding) and July (after flooding). Carabidae, Formicidae, and Gryllidae dominated HLF. Carabidae and Formicidae were the primary dwellers of HLF on the outside and inside the lake, respectively. A result of Nonmetric-Multi Dimensional Scaling (NMDS) ordination was concluded that two lakeside does not show different terrestrial arthropods assemblages but outside of HLF showed higher terrestrial arthropods. The sensitivity of Carabidae to flood event and their existence in floodplain ecosystems are identification tool for successful floodplain restoration. ABSTRAK.Karakterisasi artropoda tanah yang mendiami dataran banjir danau Hanjulutung (DBDH) dilakukan. Artropoda tanah dijebak dengan perangkat sumur jebakan yang dipasang pada kedua sisi danau di sembilan lokasi yang berbeda dengan dua waktu pengambilan sampel, Bulan April (sebelum banjir) dan Juli (sesudah banjir). Komposisi artropoda tanah penghuni DBDH adalah didominasi kumbang karabid, semut, dan belalang. Kumbang karabid dan semut adalah penghuni utama DBDH pada masing-masing bagian danau. Hasil Ringkasan ordinasi Nonmetric-Multi Dimensional Scaling (NMDS) menyimpulkan bahwa kedua bagian danau tidak menunjukan perbedaan komposisi dan struktur artropoda terestrial tetapi sisi luar DBDH menunjukan kekayaan atropoda tanah yang lebih tinggi. Kepekaan kumbang karabid terhadap kejadian banjir dan keberadaannya di dataran banjir merupakan alat identifikasi keberhasilan restorasi dataran banjir.

Hospitalitermes nigriantennalis sp. n. is readily distinguished in the field from related Hospitalitermes spp. by the light brown to orangish coloration of the soldier head capsule that, further, is with vertex yellowish and nasus brownish. The soldier antenna and the maxillary and labial palps are blackish. By contrast, soldiers from other species of Hospitalitermes from this region have a uniformly black head capsule and antennae. Finally, H. nigriantennalis sp. n. has a minute indentation in the middle of the posterior part of head capsule, which further helps to differentiate this new species from other Hospitalitermes from the Indo-Malayan and Austro-Malayan regions.

Their variation in diversity can be used as bioindicator of environmental quality. However, termite community response to land use changes and habitat disturbance in highland ecosystems remains poorly under stood. This study was conducted to investigate the response of termite community to land use intensification and to explore their role as environmental bioindicator in Mount Slamet. A standard survey protocol was used to collect termites in five land use typesof various disturbance levels,i.e. protected forest, recreation forest, production forest,agroforestry, and ur ban area. It was found two termite families i.e. Rhinotermitidae and Termitidae with seven species, i.e Schedorhinotermes javanicus, Procapritermes sp, Pericapritermes semarangi, Macrotermes gilvus, Microtermes insperatus, Nasutitermes javanicus, and N. matanganensis. Termite species’ richness and evenness, Shannon-Wiener index, relative abundance, and biomass of termite were declined along with the land use types and disturbance level from protected forest to urban area. Habitat disturbance was the main declining factor of termite diversity. Termite composition changed along with the land use disturbance level. Soil feeding termites were sensitive to the disturbance – they were not found in urban area. Hence, their presence or absence can be used as environmental bioindicator to detect habitat disturbance.

The presence of organisms provides response of habitat alteration can be used as indication organism. Indication organisms or bioindicator are key component in ecosystem management. This paper aims to evaluate and review the role of termites as bioindicator. Bioindicator defined as organisms or group of organism reflect and inform the ecosystem circumstance; environmental, ecological and biodiversity status as well as. Main criteria of bioindicator are as follow: taxonomical and biological characters of these organisms well-knew, cosmopolitan organisms, they have a well-response to habitat alteration, and their responses are closed correlated to all communities or properties of stress factors. Termites showed responses to environmental change, especially in habitat alteration. Termites responded to habitat alteration on termites composition change and termites richness decrease. Furthermore, termite’s richness strong correlated with other taxon in their community. Biological and taxonomical termites are well-known. In addition, standard survey of termites has been developed to explore termite’s richness in tropics ecosystems. These implication, termites can be applied as one of indication organisms or bioindicator, notably their relation in ecological indicator and biodiversity indicator.

Termites play an important role in the process of decomposition, nutrient turnover, and other processes in the soil. Land use change and their intensification plays a major role in the destruction of habitat and loss of biodiversity. Habitat destruction and loss of biodiversity affect ecosystem health and ecosystems function. Termites have the sensitivity to land use alteration and the level of habitat destruction that can be used as environmental bioindicator. Generally, research on the sensitivity of termites to land use was conducted in the lowland ecosystem, study the highland ecosystem remain poorly investigated.

However, is the role of seminatural habitats on oil palm plantation also identity with termite’s biodiversity? Contribution seminatural habitat studies on termite’s biodiversity (especially on oil plam plantations) were rarely conducted. This research was done on PT. Bisma Dharma Kencana oil palm plantation consension located on Katingan district, central Kalimantan. On this research, termite assemblage in oil palm plantation and seminatural habitats were surveyed and were identified as oil plam plantation pests. Termites transects were placed to assess termites assemblage on five sites were chosen for study. Nine termite species were collected comprised two member of Rhinotermitidae (i.e. Coptotermes sp. and Schedorhinotermes sp.) and five species belonged Termitidae (i.e. Prohanitermes sp., Globitermes sp., Microcerotermes sp., Termes sp., Procapritermes sp., Pericapritermes sp., and Nasutitermes sp.). Seminatural habitat on oil plam plantation can conserve termite biodiversity. Two species of Rhinotermitidae are potential pests on oil palm plantation. Nevertheless, their termite control should implemented carefully.

Termites play an important role in the process of decomposition, nutrient turnover, and other processes in the soil. Land use change and their intensification plays a major role in the destruction of habitat and loss of biodiversity. Habitat destruction and loss of biodiversity affect ecosystem health and ecosystems function. Termites have the sensitivity to land use alteration and the level of habitat destruction that can be used as environmental bioindicator. Generally, research on the sensitivity of termites to land use was conducted in the lowland ecosystem, study the highland ecosystem remain poorly investigated.

Review the plants seen every week after planting, when the crop results are seen at the end of the observation. Weed in each plot is collected and the competition is weighed dry weight for the basis of calculating the competition value. The average of each variable requested by subsequent analysis of variance for further approval with the DMRT test at 5% significance level. This study determines plant spacing affects all plant yield variables such as (number of fruits and fruit weight either per plant or per plot) while the weeding frequency increases in increasing number of leaves. In general, the combination of S3J1 and S0J1 showed the best response to the number of fruits produced compared to other treatments. Furthermore, the distance and frequency of weeding increases the percentage of weeds and can increase the competition value of beans with weeds. The combination of S1J2 treatment determines the value of competition compared to other treatments and is able to reduce weed occupation by about 22%. The two main weeds in this study are Cyperus rontundus and Ageratum conyzodies.

PENDAHULUAN A. Latar Belakang Suatu ekosistem selalu melakukan hubungan interaksi satu sama lain baik bersifat intraspesifik maupun interspesifik. Mekanisme ini dilakukan suatu tanaman untuk memperoleh bahan kehidupannya berupa unsur hara yang terdapat di tanah maupun udara, air dan sinar matahari serta ruangan untuk tumbuh dan berkembang. Mekanisme pertahanan diri ini sering merangsang tanaman untuk melakukan suatu metabolisme sekunder yang produknya biasa diendapkan dalam organ tumbuhan tersebut maupun dieksudat keluar untuk menolak kompetitor lainnya. Produk metabolisme suatu tanaman ini sering memainkan peranan penting dalam interaksi ekologis, mereka dapat menghambat herbivory, perlindungan terhadap patogen, alelopati, asosiasi simbiosisme, peningkatan perkecambahan, interaksi dengan pollinator, disamping itu juga perlindungan terhadap sinar ultraviolet maupun suhu tinggi (Lambers et al. 1998). Kajian tentang alelopati untuk pertama kali umumnya dilakukan pada ilmu kehutanan. Alelopati dapat mempengaruhi banyak aspek pada ekologi tumbuhan, meliputi pertumbuhan, suksesi tanaman, struktur komunitas tanaman dominansi, keragaman produktivitas tumbuhan. Pada awalnya kajian tentang alelopati hanya menekankan pada efek negatig alelopati pada tanaman pangan, namun sejak tahun 1980an penelitian alelopati mulai mengindentifikasi tanaman kehutanan yang memberikan pengaruh menguntungkan, netral dan selektif terhadap tanaman pangan. Perkembangan terkini, kajian tentang alelopati mulai mengamati pertumbuhan yang tidak baik pada tanaman kehutanan, kerusakan tanaman pangan, pengurangan prduksi, masalah replant untuk pohon hortukultura, kwasan bebas gulma, dan pola perubahan pada vegetasi (Ferguson & Rathinasabapathi, 2003) Krebs (2001) yang menyatakan bahwa allelopati (Allelopathy) adalah salah satu mekanisme penghambatan penyebaran suatu jenis dalam kompetisi karena kehadiran organisme lain. Menurut Molisch (1937) dalam Junaedi et al. (2006) alelopati adalah

Conservation efforts are carried out by reintroduction. However, the success of the reintroduction process depends on the treatment process at the rehabilitation center. The observation of the daily behavior of orangutan infant was done at the Protect Our Borneo (POB) rehabilitation center for 15 days. The focal animal sampling technique was applied to observe the daily behavior of two orangutan infants. Each orangutans activity is observed for four hours per day from 08.00-17.00. The dominant daily activities performed by both orangutan infants are moves, followed by feeding and playing. As for agonistic and rest activity tend to show little difference in sequence. Daily activities of orangutan infants are done more in the morning. Daytime is mostly used for rest. The afternoon activity is done to move and feed in the afternoon with a lower intensity. The daily activities of orangutan infants are affected by age, life history, types and modes of nurture. Indications of success for care of orangutan infants at rehabilitation center such as adaptability and improvement of daily behavior of orangutan children according to wild behavior.

environmental quality. However, termite community response to land use changes and habitat disturbance in highland ecosystems remains poorly under
stood. This study was conducted to investigate the response of termite community to land use intensification and to explore their role as environmental bioindicator in Mount Slamet. A standard survey protocol was used to collect termites in five land use typesof various disturbance levels,i.e.
protected forest, recreation forest, production forest,agroforestry, and ur
ban area. It was found two termite families i.e. Rhinotermitidae and Termitidae with seven species, i.e Schedorhinotermes javanicus, Procapritermes sp, Pericapritermes semarangi, Macrotermes gilvus, Microtermes insperatus, Nasutitermes javanicus, and N. matanganensis. Termite species’ richness and evenness, Shannon-Wiener index, relative abundance, and biomass of termite were declined along with the land use types and disturbance level from protected forest to urban area. Habitat disturbance was the main declining factor of termite diversity. Termite composition changed along with the land use disturbance level. Soil feeding termites were sensitive to the disturbance – they were not found in urban area. Hence, their presence or absence can be used as environmental bioindicator to detect habitat disturbance.
