Abstract

Penelitian bertujunan mengamati serangga-serangga hama penting yang menyerang tanaman tebu di PTPN VII, Cinta Manis Sumatera Selatan, dilakukan dari bulan Februari sampai September 2012. Metode survei langsung ke pertanaman dengan mengikuti jadual early warning system (EWS) PTPN VII. Hasil penelitian menemukan serangga hama penting tanaman tebu ialah penggerek batang bergaris (Chilo saccharipaghus), penggerek batang berkilat (Chilo auricilius), dan penggerek pucuk (Scirpophaga nivella). Gejala serangan penggerek batang dan pucuk tebu ditemukanpada umur 2 bulan, serangan tinggi pada umur 3-5 bulan, hal ini berkaitan dengan cuaca. Pada saat penelitian dilakukan serangan tertinggi terjadi pada bulan Mei sampai Juli, dengan suhu, curah hujan, jumlah hari hujan, dan kelembaban nisbi berturut-turut adalah 26,6OC, 245,5 mm, 17 hari dan 98%. Serangan pada tanaman muda, menyebabkan kematian. Pada tanaman yang sudah membentuk ruas, gejala penggerek batang jelas terlihat dari luar jika daun tebu diklentek. Gejala serangan penggerek pucuk terlihat pada helai daun yang berlubang.Intensitas serangan penggerek batang tertinggi pada umur tebu 3 bulan (6,69%), sedangkan intensitas serangan (2,97%) dan populasi penggerek pucuk (44,60 larva) tertinggi pada umur 3,5 bulan.The research aimed to observe the important pest insects attacking sugarcane in PTPN VII, Cinta Manis,South Sumatra. Direct Survey methodto the crop by following the schedule ofearly warning system (EWS) of PTPN VII, conducted from February to September 2012. The results found that important insect pests attacking sugarcane werestriped stem borer (Chilo saccharipaghus), shiny stem borer (Chilo auricilius), and shoot borers (Scirpophaga nivella). Symptoms attack of shotand stemborer of sugarcane were found at 2 months of sugarcane age, high attack at the age of 3-5 months, it is highly related to weather.The highest attack occurred in May and July, with the temperature, precipitation, number of rainy days, and the relative humidity in were 26.6 oC, 245.5 mm, 17 days and 98% respectively. Attack on young plants, causing death. In plants that were already established segments, stem borer symptoms clearly visible from the outside ifsugarcane leaves were diklentek. Shoot borers attack symptoms seen in the perforated leaves. The highest intensity attackof stem borer was at 3 months of sugarcane age (6.69%), while the attack intensity (2.97%) and the highestpopulation of shoot borer(44.60 larvae) were at3.5 months of sugarcane age.

Abstract

Contaminated- agro ecosystem influences abundance and diversity of arthropods. The aims of this study were to analyze the diversity and abundance of pre-planting arthropod predators on wild plants in rice field with and without application of pesticides. The survey and direct observation of wild plants at the rice filed were conducted from January to March 2015, at 1 ha in Pemulutan and 1 ha in Musi 2 Palembang. Sampling of arthropod predator was conducted 8 times before the rice was grown, using insect nets. On the land without pesticide application was found 14 arthropod families which consists of 28 species and 15 families of wild plant consists of 25 species. On the land with pesticide application was found 8 arthropod families consists of 16 species and 15 wild plant families with 23 species. On the land without pesticide application was found High index of diversity (H=3.121) and low dominance (D=0.095), while on the land with pesticide application low index of diversity (H=2.602) and high dominance (D=0.171). It is the indicators of arthropods predator more varieties at the land without pesticide application compare to the land with pesticide application. This finding is very important for biological pest management in South Sumatra.

Abstract

The abundance and diversity of arthropod in agro ecosystem depend on the level of synthetic pesticide contamination.  This study aimed to explore, identify and analyze the diversity and abundance of predatory arthropods in swamp rice fields treated with pesticide application (in Pemulutan) and without pesticide application (in Musi 2). The swamp rice fields in Pemulutan are bordered by village, river and forest. The methods were survey and direct observation on 3 ha and 2 ha of swamp rice fields in Pemulutan and Musi 2, Palembang. Sampling of predatory arthropods were conducted at 20, 50, 80 and 110 days after rice planting using pitfall trap.  Identification of  predatory arthropods  was conducted at Laboratory of Entomology showing that the arthropod collected consisted of 17 species of insects and 9 species of Arachnida. In Pemulutan Ogan Ilir were found 19 species (10 species of insect and 9 species of Arachnida) at the village area. In the area that was bordered by river were found 8 species (7 insect and 1 Arachnida). In the area bordered by forest were found 22 species (10 species of insects and 12 species of Arachnida). The diversity level, number of species, and arthropod specimen in the field without pesticide application at Musi 2 were higher than those in the fields with pesticide application in Pemulutan.

Abstract

Waste, both organic and inorganic, has become a global problem. Waste generated from kitchen activities, such as leftover vegetables and fruit, contributes significantly to the waste problem. This community service activity aims to train people in Sungsang IV Village, Banyuasin II Distric, Banyuasin Regency, to process vegetable and fruit waste resulting from kitchen activities to be eco-enzymes and their derivative products. Activities are carried out for 3 months, starting from initial preparation of situation and needs analysis. Implementation in the field involves socialization and training methods for making eco-enzymes and their derivative products in the form of soap and fertilizer. As a result of this activity, the people of Sungsang IV Village succeeded in making 50 liters of eco enzymes and 20 liters of liquid soap. In this activity, the community was also given training to use eco-enzymes as fertilizer. Training participants are taught to grow organic vegetables in their home yards by using eco-enzymes. The people in Sungsang IV village have a high curiosity about new and positive things. They enthusiastically took part in the training and as a result, on October 7, 2023, they participated in an exhibition for MSMEs making eco-enzymes and their derivative products. The Exhibition was organized by the Banyuasin Regency Government.

Abstract

The aims of this study were to find out how the growth and yield of sorghum (Sorghum bicolor L.) responds to the application of bokashi fertilizer and got the best dose of bokashi fertilizer for growth and yield of sorghum. This study was designed using a Randomized Block Design (RBD) experimental method. Giving of bokashi fertilizer with various dosages in sorghum plants can give a good response to the growth and production of sorghum plants. Giving of bokashi fertilizer with a dosage of 15 tons/ha or equivalent to 6.48 kg/plot (P3) resulted better plant growth than other treatments, with an average plant height of 204.94 cm at the age of 56 days after planting (DAP), the number of tillers flat average 5.50 tillers at the age of 28 DAP, fastest flowering age was 55.75 DAP, average wet biomass 1710.25 g/plant, fresh weight cobs in average of 129.06 g/plant, average yield was 1892,50 g/plot, average of weight of 1000 seeds was 12.63 g. Giving of bokashi fertilizer with a dosage of 17.5 tons/ha or equivalent to 7.56 kg/plot (P4) resulted the number of leaves in average of 17.69 at the age of 56 DAP and panicle length average of 40.06 cm. Giving of bokashi fertilizer with a dosage of 10 tons/ha or equivalent to 4.32 kg/plot (P1) resulted the number of panicle branches in average of 46.75 branches.
