Abstract

This study aims to determine the level of behavior of organic rice farmers in carrying out environmentally friendly rice cultivation, the relationship between farmer group support and other factors related to the behavior of organic rice farmers in carrying out environmentally friendly rice cultivation in Purwo Kencono Village, East Lampung. This research was conducted in Purwo Kencono Village, Sekampung Udik District, East Lampung Regency in October 2022. The respondents in this study were members of the Multi Baliwo farmer group with 30 people in total This study uses the census method with a descriptive-quantitative approach using data testing using non-parametric statistics using Spearman's Rank correlation test. The results showed that the behavior level of organic rice farmers was in the medium category. In this study, there are four factors that influence the behavior of farmers, namely: age, education level, and length of farming, but the results of the Spearman Rank correlation test show that only farmer group support is related to the behavior of organic rice farmers in carrying out environmentally friendly rice cultivation with a significance value of 0.487. ** which means the correlation strength is quite strong. Farmer groups have tried to maximize their role for organic rice farmers, especially in improving the behavior of organic rice farmers in carrying out environmentally friendly rice cultivation

Abstract

Red onion (Allium ascalonicum L.) is a horticultural plant needed by household consumers as a complement to cooking spices and traditional medicines. Shallot production does not meet market demand in Riau, so it is necessary to bring in shallots from other regions. Efforts to increase shallot production continue to be made to meet market demand in Riau. One of the efforts that can be made to increase the production of shallot plants is through the use of natural growth hormones (ZPT). This research aims to determine the respective effects and interactions of giving concentrations of coconut water and NPK fertilizer on the growth and yield of shallot production. This research is a factorial experiment prepared using a completely randomized design (CRD) consisting of 2 factors, namely the concentration of coconut water and the dose of NPK fertilizer. Factor I: Coconut water concentration which consists of 4 levels, namely: A0 = without coconut water, A1 = 50% coconut water (500 ml coconut water + 500 ml water), A2 = 75% coconut water (750 ml coconut water + 250 ml water) and A3 = 100% coconut water (1000 ml coconut water). Factor II: NPK fertilizer dose consisting of 3 levels, namely: N1 = NPK 125 kg.ha-1, N2 = NPK 250 kg.ha-1, and N3 = NPK 375 kg.ha-1. . Data from the analysis of variance were further tested using Duncan's multiple range test at the 5% level. The research results showed that the combination of coconut water with a concentration of 100% and NPK fertilizer with a dose of 250 kg.ha-1 increase plant height, increase tuber diameter, increase fresh tuber weight per m2 and weight of storable tubers per m2.

Abstract

This study aimed to determine the habitat approach on potato cultivation to increase diversity of insects. Habitat improvement design by agricultural system and planting system on different season. This study consisted of two experiments. The first done at planting season from March to July (dry season) and the second done at planting season from October to January (rainy season). Research designed by Split plot design with main plot are farming systems (inorganic farming and organic farming) and the subplot are the design of cropping system (sole potato; potato and cabbage; potato and mustard; potato and onion). The data was analyzed by ANOVA and Tukey test. The result showed that planting season from March to July (dry season) as well as the planting season from October to January (rainy season) showed that insect diversity index, predator population and parasitoid population were higher in organic farming compared to inorganic farming systems. The design of cropping system significantly affect insect diversity index,natural enemies population such as predator Coccinelids and parasitoid Braconid wasp and M. persicae population. In organic farming, intercropping potato with cabbage found the highest insect diversity index and the highest population of parasitoid Braconid wasp and the lowest population of M. persicae. The highest population of predator Coccinelids found at interropping potato with mustard. Combined analysis of the planting on dry season and rainy season showed that insect diversity index and population of parasitoid Baraconid wasp not significantly difference between planting on dry planting and planting on rainy season. On the other hand, population of predator Coccinellids and M. persicae significantly more higher at planting on dry season than planting on rainy season.

Abstract

Misuse of chemicals, such as borax, as an additive in food is still common. This abuse is intended to increase elasticity and crispiness for longer in food products, even though borax is prohibited in the food industry. Some food products on the market that often contain borax are tofu, meatballs, noodles, and crackers. Research studies and mass media in several traditional markets in Indonesia have proven and verified the presence of borax in crackers. Based on this, we want to know whether there is the same thing in the distribution of crackers at Blauran Market, Salatiga City. Therefore, this research aims to quantitatively determine the status of borax in crackers sold at Blauran Market, Salatiga City, in 2023—a quantitative descriptive research method. Sampling used the purposive sampling method. The research design used was a completely randomised factorial design. The first factor is the type of cracker, consisting of four levels: gendar cracker brand X, gendar cracker brand Y, white eggplant cracker brand minute. Each treatment combination was repeated three times to obtain 24 experimental units. Quantitative test of samples using a UV-VIS spectrophotometer. Data processing using two-factor ANOVA with replication. The test results showed that the four brands of cracker samples contained >100 ppm borax. The highest borax content was in white eggplant crackers.

Abstract

The alignment of economic growth between the processing industry sector and the agricultural sector in the economy will encourage the transfer of surplus labor from the agricultural sector to the processing industry sector. Furthermore, these conditions will have an impact on marginal increases in labor productivity and income in the agricultural sector as well as demand for processing industry products. This study examines the structure of demand and supply, output, gross value added, and final demand of the processing industry sector in the economy of East Nusa Tenggara. The study was conducted from April to October 2023. The analysis method used is a quantitative analysis of the East Nusa Tenggara Input-Output Table in 2020 which was compiled from the update of the East Nusa Tenggara Input-Output Table in 2017. The results of the analysis show that based on the output and gross value added generated in the economy, the food and beverage industry sector can be categorized as a leading processing industry sector. The processing industry sector uses inputs that mostly come from production within the region and the final demand of the sector is mostly used for household consumption. Policymakers need to prioritize the development of the leading processing industry sector, namely the food and beverage industry sector based on domestic inputs, especially inputs originating from the agricultural sector to increase competitiveness and be able to meet intermediate demand by other economic sectors and export needs. In addition, it is also necessary to increase profitability, productivity, and output growth in the food and beverage industry sector to increase its competitiveness and a more conducive investment climate because future investment opportunities are still quite large.

Abstract

This study aims to measure  the production function and  technical efficiency of shallot farms in Indonesia using a stochastic frontier and inefficiency effect model. The data used secondary data from national agricultural census data in 2013, which is consisted of  with , which is consisted of 11,206 shallot farms,  is employed as the unit of analysis. The data consists of six conventional inputs and several other background factors affecting shallot production spread across 33 provinces of Indonesia. Results from this study indicated that all inputs significanly affect shallot production in Indonesia. Labor was the most elastic input. The average value of technical efficiency of shallot farms is 0,82. The results show that shallot farms in Indonesia is still inefficient and there is a 18% chance to increase the production.   The variables of inefficiency which significaly affected the production are age of farmers, education, proportion of self finance, government subsidy, cooperative, farmers group and the degree of commercialisation. Contract farming membership is not real.

Abstract

Sugarcane (Saccharum officinarum L.) is a plant that is cultivated to be processed into sugar. However, until now Indonesia has become a sugar importing country because the sugar industry is unable to meet the needs and demand for sugar which continues to increase as well as the high domestic selling price, so that it is necessary to import sugar to meet the demand for sugar in Indonesia. To overcome this is to apply Nitrogen fertilization on sugarcane combined with a companion material in the form of Zeolite. This study aims to obtain the growth and yield of ratoon 2 sugarcane plants by administering Zeolite and the proportion of N fertilizer as well as the interaction between the Zeolite and the proportion of N fertilizer. This study used a Randomized Block Design (RAK) Arranged in a split plot with two treatment factors repeated 3 times with 6 treatment combinations to obtain 18 experimental units. The main plot of Zeolite dosing with Z₀ is without zeolite and Z₁ is 700 kg.ha⁻¹ (equivalent to 0.8 kg.8m kairan⁻¹). Subplot dosage proportions of N fertilizer with P₁ is 100% urea (equivalent to 0.36 kg. 8m caustic⁻¹), P₂ is 80% urea (equivalent to 0.28 kg. 8m caustic⁻¹), and P₃ is 60% urea (equivalent to 0.21 kg. 8m caustic⁻¹). The results of this study indicate that the dose of Zeolite has an effect on all variable parameters of growth observations which include plant height, stem diameter, and number of internodes. As well as plant yields which include stem weight, stem length, brix value and yield. Application of [dose percentage of N fertilizer did not affect the growth and yield of sugarcane plants. There was no interaction between the Zeolite dosage and the proportion of N fertilizer doses on the growth and yield of sugarcane
