Pujiastuti et al, 2017. Production of Bacillus thuringiensis Spores in Agricultural Waste with Addition of Golden Snail Shell Powder and its Toxicity Against Spodoptera litura Fabr. (Lepidoptera: Noctuidae). JLSO 6(2):150-157.Armyworm or Spodoptera litura is an important pest on the cultivation of plants. Controlling by using biological agents such as Bacillus thuringiensis is an alternative to the use of chemical insecticides which cause a negative impact on insects and environment. B. thuringiensis-based bio insecticide can be reproduced by using agricultural waste with the addition of golden snail shell flour. The study was aimed to investigate the production of B. thuringiensis spores on agricultural waste media and the addition of golden snail shell flour and its toxicity to armyworm, as well. The research design was a completely randomized design with 10 treatments and 3 replications. Treatment were the media of agricultural waste: 50 mL coconut water, 50 mL of tofu liquid waste, 50 mL of rice wash water and mixture of three media (v/v/v, 1:1:1) with the addition of golden shell flour as much as 5 g and mineral salt of CaCl2, MgSO4, K2HPO4, KH2PO4. The results showed the production of bacterial spores ranged from 8.90x107 spores/mL to 9.51x107 spores/mL with the highest production in the mixed treatment of the three waste media (coconut water, tofu waste and rice laundry water). In this treatment the level of toxicity was 40% in larvae of armyworm. The weight of leaf feed consumed by armyworm at various treatments was ranged from 36.33 to 46.67 g/10 larvae. The addition of mashed shell flour to growth media of B. thuringiensis did not increase the number of spores.

Asam-Basa adalah salah satu materi penting yang dipelajari di SMA yang mencakup pemahaman konsep dasar dan melibatkan representasi makroskopik, mikroskopik dan simbolik. Hal ini menyebabkan materi asam-basa cenderung sulit dipahami oleh siswa. Kesulitan mempelajari materi Asam-Basa berpotensi menimbulkan miskonsepsi. Oleh karena itu perlu dilakukannya identifikasi miskonsepsi. Penelitian ini merupakan rancangan deskriptif untuk membandingkan keefektifan tes pilihan ganda tiga tingkat terhadap tes pilihan ganda diikuti wawancara dalam mengidentifikasi miskonsepsi asam-basa. Subjek penelitian ini adalah dua kelas homogen dari kelas program IPA pola lima semester SMAN 8 Malang. Hasil penelitian menunjukkan bahwa tes pilihan ganda diikuti wawancara lebih efektif dibandingkan tes pilihan ganda tiga tingkat. Terdapat sembilan miskonsepsi yang dialami siswa, empat diantaranya merupakan miskonsepsi yang belum ditemukan pada penelitian lain.

The fermentation of cocoa beans is an important part of cocoa processing. Fermentation of cocoa beans increases the quality and price of the beans and the resultant cocoa. Although the fermentation of cocoa beans can increase the quality and income of cocoa farming, few farmers in Indonesia implement this fermentation process. This research therefore, focuses on the way Indonesian farmers assess whether or not to ferment their cocoa beans. A total of 284 cocoa farmers were sampled in Central Sulawesi Indonesia. The results showed that out of the more than 50% of farmers who did not ferment their cocoa beans, a majority were simply not interested in increasing the quality of the resultant cocoa. The quality of cocoa beans produced from smallholder plantations, therefore, was continually poor. The decision of cocoa farmers to ferment their cocoa beans, meanwhile, was significantly affected by the gender, age and education level of the head of the household, the number of productive family members, the quantity of cocoa bean production, and the resultant price of the fermented cocoa beans in the market. The resultant price of the fermented cocoa was the most dominant factor.

This research aim was to identify (1) The income level of monoculture and intercropping coconut farms and (2) the relationship of increasing capital and income in farm coconut. The research location was purposively chosen at Panii Village, Damsol Subdistrict of Donggala Regency. Respondents were randomly determined the toss system based on the assumption that the coconut farm condition was homogeny including: (1) land area size, and (2) self own farm. The number of population was 101 households within which 51 household samples were chosen (19 households for monoculture coconut farm and 31 households for intercropping coconut farm). The product moment correlation was used to analyze the relationship of increasing capital and income while descriptive analysis was used to identify the income level. Results of research indicated that (1) the average income of the monoculture and intercropping coconut farms were IDR 2,266,881.53 and IDR 4,859,982.97 ha-1 harvesting-1, respectively, and (2) the correlation of capital and income in coconut farm at Panii village was positive and significant.
