Abstract

This study aims to analyze the effectiveness of community empowerment using village funds in developed and developing villages. This research employed a survey method on multiple case studies involving 70 respondents. Data were analyzed using a quantitative approach. The results showed that the effectiveness of community empowerment program is more effective in the developed village. The variables of community awareness, participation, independence, and income have a positive and significant effect on the effectiveness of the community empowerment program.

Abstract

Maluku is a province in eastern Indonesia that has experienced prolonged conflict due to racial and sectarian issues. This conflict can be resolved when the state through the military changes its approach from security to prosperity. With the synergy of the military and civil society as the basic foundation of the Green Gold program, Maluku has transformed into a producer of high-value timber such as agarwood (Aquilaria Malaccensis) and sandalwood (Santalum Album) from their production forests. This research aims to analyze the institutional governance of production forests in Maluku using the Institutional Analysis and Development (IAD) framework as an analytical tool. To analyze the above phenomenon, this research used a descriptive qualitative approach with data collected from interviews and literature studies. The research results showed that: First, in terms of Attributes of the Resource, it was found that basically local users have managed the production forest resources quite well, but they still have a high dependence on military assistance. Second, in terms of Attributes of the Users, it was found that the community has a high sense of belonging to the forest. There is an assumption that if they do not manage the forest well, it will be difficult for them to escape from conflict. Therefore, in order to realize community self-government over the forest, the military gradually reduced its role.

Abstract

Lembah Gumanti District has the largest area of Arabica coffee in Solok Regency, with a production of 2588.8 tons in 2019. Some problems farmers face in developing Arabika coffee farming include a lack of knowledge of cultivation techniques and low selling price of coffee (cherry) beans at the farm gate. The Solok Radjo Cooperative emerged to solve farmers' problems and is willing to help develop Arabica coffee plantations in partnership. This study aims to: (1) describe the implementation of partnerships in Arabica coffee farming and (2) analyze the feasibility of arabica coffee farming with partnership pattern. A survey method was used involving 40 sample farmers selected using simple random sampling. Data analysis was carried out qualitatively to determine the implementation and benefits obtained by the partnering parties (farmers and Solok Radjo Cooperative). Quantitative analysis is intended to determine the financial feasibility of developing Arabica coffee with a partnership pattern. In the partnership system, the Solok Radjo Cooperative provides farmers assistance to use superior seeds, socialization of Arabica coffee cultivation and harvesting techniques, and willingness to buy coffee beans (cherry) from farmers with higher prices than local collectors. The benefit obtained by the Solok Radjo Cooperative is the guaranteed supply of Arabica coffee production with better quality. Arabica coffee plantation business through this partnership is feasible with a Net BC ratio of 2.43.

Abstract

This study aims to analyze the factors affecting the productivity of smallholder tea farming in Solok Regency. Sixty-five tea farmers, selected using a simple random sampling approach, were involved in this study. The study reveals that urea fertilizer, SP-36 fertilizer, insecticides, labor, plant age, and seedling varieties significantly affect tea yield at the level of α = 0.10. Farmers can increase the yield of tea farming by increasing fertilizer and labor and intensive pest and disease control. Gambung variety produces a higher yield than TRI, and the yield increases with the age of the plant.

Abstract

The botanical insecticide nanoemulsion is a pesticide having an oil phase and aqueous phase that spontaneously emulsify and range in size from 20 to 200 nm. Bio-combi extracts frequently contain intricate combinations of active ingredients that may work in concert to increase bioactivity. The goal of the study was to develop the optimal nanoformulation and investigate the physiological effects of a synergistic nanoemulsion made from Tephrosia vogelii leaves and Piper aduncum fruit extracts as a substitute pesticide for Spodoptera frugiperda larvae. Low-energy spontaneous emulsification with a magnetic stirrer was used to create nanoemulsions, which were then subjected to a toxicity and food absorption test. Malvern's Zetasizer Nano (ZN), which was used to analyze the insecticidal nano formulae for PSA, revealed that the particle sizes for the 1:1, 3:1, and 1:5 ratios were 204 nm, 4724 nm, and 97 nm, respectively. Only the 1:5 formula, which is classified as a nanoparticle, met the standards for a nanoemulsion and produced S. frugiperda mortality of 82.34% at a concentration of 0.56%, and the LC25, LC50, and LC95 values were 0.1, 0.22, and 1.59%, respectively. The analyzable results demonstrated that the mixed nanoemulsion was additive at the LC50 value was 0.95 while the LC95 value was 0.70%, meaning only marginally synergistic

Abstract

The bacterial species Xanthomonas axonopodis pv allii (Xaa) is an important pathogen causing leaf blight in shallots. The use of botanical pesticides with nanoemulsion formulations has become a common alternative. This study aims to determine the characteristics and optimum concentration of the mixture of essential oil of Piper aduncum and fragrant Cymbopogon nardus waste. Nanoemulsion formulations are made using spontaneous emulsification methods. Besides, testing Bacillus thuringiensis strain MRSNR3.1 and its secondary metabolites toxicity against Xaa was carried out by the diffusion method using paper discs to determine the diameter of the inhibition zone. The results demonstrate that all four concentrations, 1%, 2.5%, 5%, and 7.5%, could control Xaa bacteria. A concentration of 1% is considered more optimal than the other three   concentrations in bactericidal effects against Xaa, as manifested in the formed clear zone (diameter of 3.17 cm). Besides, Bacillus thuringiensis strain MRSNR3.1 and its secondary metabolites were also effective againstXaa after four days of incubation with inhibition zones of 3.04 ± 0.44and 2.21 ± 0.28, respectively. Hence, it is concluded that nanoemulsion at 1% concentration and Bacillus thuringiensis strain MRSNR3.1 have  bactericidal properties that can be used to control Xaa

Abstract

Food loss is a worldwide concern, especially the losses from the fresh tubers because of their quick rottenness during post-harvest without proper preservation. Meanwhile, the tuber is an excellent source of carbohydrates that can be used in a broad range of food and other industries. Therefore, creating added-value products from crops has been considered an intriguing idea for decades in order to reduce this matter and also can utilize raw materials from agriculture. This research aimed to determine and evaluate the effects of starch addition from Jicama on the characteristic of peel-off gel masks. Five different formulations were made with increased starch concentration at 1%, 2%, 3%, and 4%, and a control sample was formulated without adding starch. Organoleptic, spreadability, homogeneity, irritation, viscosity, pH, peeling time, and antibacterial and antioxidant activity were parameters in evaluating gel formulations. The best formula showed a homogenous consistency, there was no irritating reaction, and it had the highest sensory point from the panellist. The acidic degree and viscosity were 5.53 and 32867 cPs, respectively, which adhered to the Indonesian National Standard (SNI 2007) for facial skin products; the gel had good spreadability, and the peeling time was less than 30 minutes. Moreover, the gel presented an active antibacterial activity against Staphylococcus aureus; and antioxidant activity. According to the results, Jicama is recommended for application in making good quality peel-off gel mask products at 4% concentration.
