Abstract

Tanaman porang merupakan tanam umbi-umbian yang mengandung zat glukoman dalam bentuk gula kompleks dan serat larut yang berasal dari ekstrak akar tanaman. Porang menjadi salah satu komoditi pertanian yang mempunyai nilai ekonomi tinggi dan punya peluang cukup besar untuk di ekspor. Tujuan penelitian ini untuk mengetahui besarnya penerimaan usahatani porang, untuk mengetahui besarnya pendapatan usahatani porang, untuk mengetahui R/C ratio usahatani porang. Penelitian ini dilaksanakan di Desa Watu Manggar Kecamatan Macang Pacar Kabupaten Manggarai Barat secara Purpusive Sampling, dengan beberapa pertimbangan yaitu petani di Desa Watu Manggar telah mengembangkan tanaman porang dilahannya, dan pengembangan porang di wilayah Desa tersebut berpotensi memberikan penghasilan yang baik kepada petani. Jumlah populasi dalam penelitian ini adalah 60 orang dan sampelnya 30 orang. Data yang dikumpulkan adalah data primer dan data skunder dengan teknik wawancara, observasi dan dokumentasi. Untuk menganalisis data digunakan data kuantitatif yaitu analisis usahatani. Kesimpulan yang diambil yaitu penerimaan petani sebesar 2.100.000 dan jumlah biaya 1.214.000, rata-rata pendapatan petani porang 886.000, Besar R/C Ratio 1,72 artinya usahatani porang di Desa Watu Manggar menguntungkan.

Abstract

Thrips parvispinus is a pest of large chili plants Capsicum Annuum. This study aimed to determine the effect of spacing on the population and the percentage of T. parvispinus attacks on large chili C. annuum in Kintamani, Bangli Regency, Bali. This research has been conducting on farmer's land in Sekaan Village, Kintamani District, Bangli Regency, Bali from March to May 2021. This study used a randomized block design (RAK) method, with three treatment levels and five replications. The number of plants observed in each plot was ten plant clumps using a systematic sampling method (diagonal system). The results showed differences in the number of T. parvispinus pests on large chili plants in each treatment, there was an apparent difference between the spacing treatment one (1) and the spacing treatment two (2), but the spacing treatment two (2) was not significantly different from treatment three (3). The results showed that the percentage of T. parvispinus attack on spacing treatment one (1) was higher than treatment spacing two (2) and three (3) from observation one to observation six. The relationship between harvest yields and the percentage of T. parvispinus pest attacks showed differences in harvest weight. The spacing treatment one (1) has a smaller harvest weight than the spacing treatment two (2) and three (3). So the proper spacing for large chili C. annuum is the spacing treatment two and three.

Abstract

Cabbage plants are one of the horticultural commodities that many farmers cultivate in Indonesia because they have economic value, because apart from being able to meet domestic needs, cabbage also has the opportunity to become an export commodity. This study aims to determine the percentage of attacks by the cabbage leaf caterpillar Plutella xylostella and the level of parasitization of the parasitoid Diadegma semiclausum in Kintamani District. This research was carried out in Sekaan Village and Kedisan Village. The research method uses a survey method. Sampling of cabbage plants in the field was carried out diagonally so that 5 sample points were obtained, 10 plants were observed at each sample point. The research results showed that the percentage of P. xylostella pest attacks in Sekaan Village and Kedisan Village ranged from 12% to 28%. The average population of P. xylostella larvae in Sekaan Village ranges from 0.98 individuals/plant to 1.82 individuals/plant and the highest average population of P. xylostella larvae in Kedisan Village ranges from 0.7 individuals/plant to 1.66 individuals/plant. The level of parasitization of the parasitoid D. semiclausum in Sekaan Village ranges from 32% to 56% and the level of parasitization of the parasitoid D. semiclausum in Kedisan Village ranges from 24% to 48%. The highest peak of parasitization was found in the fourth observation (4 WAP).

Abstract

cultivation techniques with mina padi cultivation techniques. This study aims to increase the productivity of rice fields in Kenderan Village, Tegallalang District, Gianyar Regency. The research method used is the experimental method with Randomized Block Design (RAK) with 2 treatments. Data analysis in this study used descriptive analysis, quantitative analysis and farming business analysis. The results of the study showed that the mina sari cultivation technique was able to produce 3 types of commodities with gonda plant production of 1,760 kg/ha, rice plants 6,780 kg/ha, and tilapia fish as much as 1,390 kg/ha. The sales results from all commodities allow farmers to earn an income of IDR 83,300,000 per hectare. Monoculture system, rice fields are only able to produce rice plants with a yield of 7,334 kg/ha. The rice yield obtained from the monoculture technique is slightly higher than the Mina Sari technique, the income from farmer sales with the monoculture system is much lower, which is IDR 44,004,000 per hectare. The results of the R/C analysis showed a value of 2.02 in the Mina Sari cultivation technique and a value of IDR 2.47 in monoculture. The R/C value in farming with the Mina Sari and monoculture cultivation techniques showed a value> 1 so that both cultivation techniques were profitable.
