Many wastes in nature made from cellulose cause problems because it is difficult to degrade, it is needs to be treated biologically by utilizing cellulase enzymes from bacteria. Some bacteria are able to degrade a cellulose compound to be used as a source of energy, there is a lot of cattle farm. The purpose of this study was to obtain bacteria that have the potential to degrade cellulose. Isolation of cellulolytic bacteria from cattle fam waste using selective carboxymethyl cellulose media, and semi-quantitative degradation of cellulose compounds was tested. The results obtained by two cellulolytic bacteria marked the formation of inhibitory zones, in BS1 is 3.2 cm and in BS2 is 2.9 cm. From the index of inhibitory values formed, these two isolates have the ability to degrade cellulose in the average category.

Bark beetles (Curculionidae: Scolytinae) has important role in the ecosystem, mainly as decomposer. In this research, we studied the diversity and abundance of bark beetles in Gunung Walat Education Forest at Sukabumi, West Java. This area located at an altitude of 500-700m asl with about 349 ha. Bark beetles were collected by pitfall traps in four types of habitat, i.e., agathis forest, pine forest, schima forest, and mixed forest. A total of 11145 individuals belong to 11 species of bark beetles were found, i.e., Poecilips variabilis, Thamnurgides sp., Cryphalus sp1., Cryphalus sp2., Xyleborus morstatti, X. propecaniclatus, X. morigerus, X. nepotulo, X. masearemsis, Xyleborus sp1, and Xyleborus sp2. Highest abundance of bark beetle was found in the schima forest (4175 individuals) and the lowest was found in pine forest (1548 individuals). Diversity of bark beetle was highest in Schima forest (H= 0,36, E= 0,26) and the lowest in Pine forest (H'= 0,27, E= 0,19). The evenness value of bark beetle in four habitat type is very low (E= 0,19 – 0,26). There are two species dominant of bark beetles, i.e P. variabilis and Thamnurgides sp. The highest number of individual bark beetles was found in Schima forest (4175 individuals; 37%) and the lowest in Pine forest (1548 individuals; 14%). The species number of bark beetles was highest in mixed forest (seven species; 41%).

Mangrove ecosystem is a habitat of various fauna, especially macrozoobenthos. The changing vegetation of the mangrove ecosystem will influence the abundance of macrozoobenthos. This study was conducted in April-August 2019 and aims to analyze the dominance and density relations of mangrove vegetation against the abundance of Macrozoobenthos on the Pagkajene coast. The research location is conducted on three stations, each station is divided into two sampling areas, and on each sampling area is placed six sampling points. Data collection of mangrove vegetation is used with a multilevel plot method and Macrozoobenthos using a plot 50x50 cm. correlation the dominance and density of mangrove vegetation towards the abundance of macrozoobenthos used linear regression analysis. The results of the study gained that the mangrove vegetation dominancy positively affects to the abundance of macrozoobenthos but insignificant. Meanwhile, the density of mangrove vegetation significantly negatively affects to the abundance of macrozoobenthos.

The research was aimed to community pond in Borimasunggu, Maros, South Sulawesi. Aiming to socialize the polyculture technology of tiger shrimp, milk fish and seaweed. Using 3 ponds each measuring 1 ha. used post larva and milkfish seeds with an average weight of 0.056 ± 0.006 g and 75 ± 2.1 g respectively. While the seaweed seeds used are gracillaria verrucosa. Seaweed spreading is done 30 days earlier then spreading tiger shrimp and milk fish. Each ponds is scattered: A = 1,500 kg of seaweed + 30,000 tiger shrimp + 1,500 milkfish; B = 1,500 kg of seaweed + 30,000 tiger prawns; C = 1,500 kg of seaweed + 1,500 milkfish with 120 days maintenance time. Daily growth rate in plot A = (tiger shrimp = 5.66%, milkfish = 1.84% and seaweed = 2.3%) and production of 165 kg of tiger shrimp, 417 kg of milkfish and 4,285.7 kg of seaweed. Daily growth rate in plot B = (tiger shrimp = 5.21%; seaweed = 2.2%) and production of 127 kg of tiger shrimp, 3,985.7 kg of seaweed. While the growth rate in ponds C = milkfish = 1.91% and seaweed = 1.08% with a production of 450 kg of milkfish and 3,085 kg of seaweed.

Rice bran is a waste of rice processing that can be used as a growth media of fungi because it contains high carbohydrates and high protein. Rice bran infusion is made in powder form using freeze-drying techniques to maintain the nutritional content of rice bran. This study aims to determine the level of carbohydrate and protein media made from bran infusion powder and determine the dose of bran infusion powder in the preparation of dextrose bran media. In this study using the Luff Schoorl method to measure the levels of carbohydrate media and the Kjeldhal method to measure the protein content of bran media. Candida albicans, Mallasezia furfur, Aspergillus fumigatus were inoculated in each medium. From this study, the highest levels of carbohydrate (9.11%) and protein (1.64%) were obtained in media using 200 g of rice bran infusion (iBDA200) and the lowest levels carbohydrate (0.44%) and protein (0.08%) wer obtained in media using 2 g of rice bran infusion powder (SBDA2). Growth of M. furfur, C. albicans and A. fumigatus the most fertile on iBDA200 media. This study shows that carbohydrate and protein content are higher in media made from bran infusion. 10 g of rice bran infusion powder (SDA10) best grows fungi but has no significant correlation with fungi growth.

Many farmers' farmlands are found to be unproductive according to their owner's wishes. The condition is sometimes left even abandoned by the owner because it does not produce economic value for the welfare of the fishermen farming community. Touch of technology is expected to change the condition of the land from idle to helpless. Therefore, a study and constructive approach was carried out in the form of reconstruction of idle land that was intrused by seawater belonging to farmer groups in the form of reconstruction of idle land into paddy fields and ponds so that it was suitable for cultivation. This activity was carried out in Oring Lawallu Village, Soppeng Riaja Barru District of South Sulawesi. The study began with a site survey, socialization and land reconstruction from an idle paddy field to paddy fields for rice and caren for shrimp farming. The area of land used is seawater intrusion land of about 1 ha, which is owned by 5 members of the Massiddie farmer group, then reconstructed using an excavator owned by the Dinas Perikanan District of Barru. The results of the land reconstruction activities consisted of 0.363 ha of land area and caren land of around 0.242 ha equipped with 0.092 ha of reservoir and the rest of the canal and dike separating between paddy fields / ponds. The lands that have been reconstructed are suitable to be used as land for cultivation of rice and tiger shrimp and other aquaculture commodities

Rice is the main commodity for most agricultural communities in Indonesia and is still main food ingredient needed by around 90% of Indonesian population. Rice production in South Sulawesi varies greatly between 3 to 7 tons per hectare of dry un-husked rice in normal season conditions. Condition of food crops in Bone District is supported by paddy fields in several districts. Bone District is area with the largest rice production in South Sulawesi. The use of biological fertilizers needs to be developed in an effort to reduce the use of synthetic chemicals. Application of biological fertilizer becomes an excellent complement, because in addition to increasing soil fertility it also spurs plant growth. Application of Mikrobat biofertilizers is carried out on rice plantations located in Bulu Allaporenge Village, Bengo Sub-District, Bone District. Process of giving Mikrobat fertilizer is carried out 15-20 DAPs (days after planting). Treatment of Mikrobat biofertilizers at a dose of 1 liter per hectare at a ratio of 1: 100. The results of application of Mikrobat biofertilizer technology have a significant effect on plant height, panicle length, number of grain per panicle and weight of 1000 grains. While variable number of tillers and percentage of empty grains had no significant effect. The response of farmers is very high to apply biofertilizer technology on rice plantations because farmers immediately see the appearance of good plant growth compared to controls (without the application of microbial fertilizer).
