Abstract

Lampung Province, as one of the largest producers of robusta coffee in Indonesia, still faces issues of low productivity. Contract farming is seen as a strategy to increase productivity and income from coffee farming. The aim of this research is to analyze the effect of contract farming on production risks and income from coffee farming. The research was conducted in Tanggamus Regency, Lampung Province. The data used in this study is secondary data obtained from the Project Cooperation Agreement (PCA). The research respondents consisted of 203 farmers, comprising 99 partner farmers and 104 non-partner farmers. Data analysis methods used the coefficient of variation to analyze the level of production risk with contract farming and the Mann-Whitney test to analyze income differences between contract and non-contract farmers. The research results showed that both contract and non-contract coffee farmers faced low production risks. Income from coffee farming by adopting a contract farming system was higher than without a contract. Additionally, the total costs incurred for coffee farming by contract farmers were lower than non-contract farmers. Income difference tests between contract and non-contract farmers indicated significant differences in both cash and non-cash income. It can be concluded that farmers under contract and non-contract farmers face the same level of risk, but contract farmers have higher incomes than non-contract farmers.

Abstract

Government Ogan Ilir Regency is committed to alleviating the stunting problem, especially for most farming families ​ suffering from stunting. The research was conducted on mothers' toddler nutrition not aged 13 to 59 months in the Farming families in nine Posyandu (Integrated Healthcare Posts) in three different sub-districts, based on the Decree of the Regent of Ogan Ilir 2023, Number 188/KEP/DPPPAPPKB/2023 concerning Lokus Village Acceleration Reducing Stunting. The sample used a purposive sampling technique with 17 questions​ grouped into three parts. Data was analyzed using descriptive quantitative and partial least squares (PLS) analysis. The research results show that factor education is the highest for mothers​ influenced by the lack of knowledge about source nutrition for toddlers. The income factor is the highest family​ influenced by the nutrition choices menu when there is money—the priority of using cash in the house and the assumption that work no means wealthy. The schedule influences the highest consumption factor. All variables have convergent validity and are related to mutual relationships. The condition results in a social economy and farming families. The incidence of stunting in Ogan Ilir Regency was 59.8 %, significantly influenced by education and income factors. The effect of the moderation factor education is confirmed to be a significant strengthening factor of income and a factor that affects the consumption of farming families and stunts incidents in Ogan Ilir Regency. Additionally, the effects​ of moderation factor income were confirmed to be very significant, strengthening factor consumption farming families to stunting incidents in Ogan Ilir Regency.

Abstract

This study aims to determine the comparison of filtration processes using filtration membranes which include Microfiltration, Ultrafiltration, Nanofiltration and Reverse Osmosis on the characteristics of lemon juice functional drinks on a pilot scale, so that the stability of product results from the four different methods can be known. The best product quality parameters in this study include vitamin C content, total acid content, total soluble solids content, antioxidant activity, pH value, viscosity value, *b value (yellowish color), total microbial reduction, and hedonic quality test (aroma, taste, and aftertaste). So that a comparison of product characteristics can be obtained. The research conducted will go through three stages including the manufacture of control juice products as a comparison, the characteristics of products processed using membrane filtration machines and data processing using t tests conducted to find a comparison of the results of these products.The results of this study are the manufacture of lemon juice functional beverages using the filtration membrane method affects the vitamin C content, total acid content, total dissolved solids and antioxidant activity because the pore size of the membrane will decrease and the particles contained in the sample will be increasingly filtered and after being compared between each method, the highest results are obtained in the microfiltration method and the lowest is reverse osmosis. The manufacture of lemon juice functional beverages using the filtration membrane method affects the pH value, viscosity and color because the pore size of the microfiltration membrane to reverse osmosis is getting smaller so that it will decrease the pH value, viscosity and color. The manufacture of lemon juice functional beverages using the filtration membrane method affects the quality of the product, where in organoleptic testing the color attributes of the MF method produce lemon yellow beverage products. At the aroma attribute, the UF method produces a typical lemon-scented beverage product. At the taste attribute, the RO method produces a very sour beverage product typical of lemon. At the aftertaste attribute, the MF method produces very bitter beverage products.

Abstract

This study aims to analyze the effect of planting distance and liquid fertilizer dosage on the growth and production of shallots (Allium ascalonicum L). This study examines the effect of a combination of planting distance and dosage of liquid organic fertilizer based on animal waste on the growth and production of shallots (Allium spp.). The study was conducted using a factorial Randomized Block Design (RAK) with two main factors, namely planting distance (D1: 20 × 20 cm, D2: 15 × 20 cm, D3: 10 × 20 cm) and dosage of liquid organic fertilizer (J0: control, J1: 250 ml/liter of water, J2: 500 ml/liter of water, J3: 750 ml/liter of water). The variables observed included plant height, number of leaves, bulb weight per plant, and bulb weight per plot. The results showed that increasing fertilizer dosage and wider planting distance significantly increased plant growth and production. ANOVA showed that planting distance and fertilizer dose had a significant effect on plant height, number of leaves, tuber weight per plant, and tuber weight per plot, but the interaction between the two factors was not significant. Application of high dose fertilizer (750 ml/liter) and wider planting distance (20 × 20 cm) resulted in optimal growth in all variables.

Abstract

This research was conducted at PT Great Giant Pineapple Plantation Group 4 (GGPPG4), located in Rajabasa Lama, East Lampung, to evaluate the effectiveness of two irrigation systems in the cultivation of crystal guava (Psidium guajava L. cv. Kristal). The mini sprinkler irrigation system was applied in Block 408 P (4.2 ha) and the drip irrigation system in Block 412 N (3.46 ha). Parameters evaluated included water uniformity coefficient, soil moisture condition, water usage efficiency, and water productivity. The results showed that the water uniformity coefficient of the mini sprinkler irrigation system reached 88.49% (classified as good), higher than the drip irrigation system, which was 77.20% (classified as fair). However, drip irrigation was more efficient in water usage with a total requirement of 2,516 m³/ha, compared to 3,260 m³/ha for the mini sprinkler system. The water productivity of drip irrigation reached 11,942 kg/m³, much higher than the mini sprinkler system, which only reached 4,965 kg/m³. Although the mini sprinkler system had better water distribution uniformity, the efficiency and water productivity of drip irrigation provided more optimal results. This study indicates that drip irrigation is superior in supporting efficient and sustainable crystal guava cultivation at the research site.

Abstract

Vanda Douglas orchid is the one of tropical famous plant especially in Indonesia. The beauty of Vanda Douglas orchid is attract people’s attention as an artifial plant, cutting flower, garden decoration and public facility. The aim of research to learn more about : KNO3 fertilization, cytokinin ZPT application which is using Benzyladenine (BA) with or without Thidiazuron (TDZ), detect if there is an interaction or no interaction between application of KNO3 and ZPT cytokinin, also shoot decapitation on the flowering of Vanda Douglas orchids. Research was held in Sanggar Bunga Douglas Kelurahan Sumur Putri, Kecamatan Teluk Betung Utara, Kota Bandar Lampung started from November 2021 to February 2022. First attempt did using a Group Random Design (RAK) with three repetation. The treatment was arranged using factorial 2x5 and the first factor was KNO3 which was K0 (no fertilizer) and K1 (10 g/l of KNO3), and second factor were variant concentrate of BA and TDZ (mg/l) : no ZPT as a control, 200 BA, 400 BA, 200BA+15 TDZ and 400 BA+15 TDZ. Each treatment combination was repeating for three times and every single research consisted of 10 Vanda Douglas orchids and the number of whole plants reach 300 of Vanda Douglas orchids. Second attempt was a factorial research with Group Random Design (RAK) consisted of 2 factor. The first factor was no shoot decapitation (P0) and with shoot decapitation (P1). Second factor were variant concentrate of BA : 0, 200, 400, 200 mg/l + 15 mg/l TDZ, and 400 mg/l + 15 mg/l TDZ. Each treatment combination was repeating for three times and every single research consisted of 10 Vanda Douglas orchids and the number of whole plants reach 300 of Vanda Douglas orchids. Data analyze did by using variant analyze and if showed the significancy, it would continued by BNT test on 5% level. Observation of first attempt started on second week after KNO3 and ZPT sprayed. Observation of second attempt started in week 24 ( or week 12 after shoot decapitation). Variable that observed were : percentage of flowery plant (%) grain length (cm) and number of bud. The result of research showed that combination between KNO3 fertilization and ZPT gave the tiny effect to Vanda Douglas orchid flowering. Application of ZPT (BA or BA+TDZ), shoot decapitation and interaction between both factors was effecting to flowery plant percentage. Only for average of grain length variable and number of bud, the variant analyze did for single factor which was ZPT application. It was caused by no shoot decapitation treatment the whole plants (120 plants) wasn’t flowery. The variant analyze showed that ZPT application had real effect to grain length and bud.
