The aim of this study was to evaluate the potential use of Noni (Morinda citrifolia L.) leaves as an antibacterial agent for Escherichia coli and Salmonella typhimurium. Noni leaves are processed with four methods i.e., mealing, blending, juicing, and decocting. The data obtained were analyzed descriptively. The variables measured were phytochemical analysis and antibacterial activity through bacterial inhibitory test. Qualitative test was used for phytochemical analysis and quantitative analysis was used for antibacterial of noni leaves. The antibacterial activity of noni leaves with diffusion well method used 4 concentrations i.e., 2.5; 5; 7.5; and 10% and extracted by maceration with 4 solvents i.e., water, ethanol, ethyl acetate, and hexane. The results showed that the processing of Noni leaves produced various active compounds. The noni leaves meal produces a more active type of compound group compared to 3 other treatments. Antibacterial tests against Escherichia coli were not seen in all noni leaves processing, but were seen to positively inhibit Salmonella typhimurium in the extraction process of Noni leaves meal using ethanol and ethyl acetate solvents at 48 hours maceration. The conclusions of the results showed that noni leaves meal extract using ethanol and ethyl acetate macerated for 48 hours was able to inhibit Salmonella typhimurium bacteria.

This study aimed to determine the feasibility of upland rice farming, the breakeven point of price and production, and the ratio of increasing profit of the jajar wayang to double row planting system. The study was conducted in Singosari Village, Mojosongo Sub-District, Boyolali District during rainy season in 2016/2017. The study of upland rice planting system was demonstrated on 4 ha of dry land, using Inpago 8 and Inpago 9 varieties which were planted in double row and jajar wayang system. The data were analyzed descriptively both qualitatively and quantitatively. The results of the analysis showed that the Inpago 9 variety grown in double row gave the highest productivity (5.5 tons/ha) compared to the Inpago 8 variety and the other cropping systems so that the profit obtained was IDR13.552.000/ha (RCR=2.99). Break even point analysis of prices and production showed that if there was a decrease in prices and production of 57.39-66.59%, the farmers did not suffer losses. Changes in the planting system from jajar wayang to double row provided a proportion of increase in profits in Inpago 8 varieties by 18.79% and in Inpago 9 varieties by 7.71%, indicating NKB value of 1.24 and 1.09. Therefore, the productivity of upland rice on dry land can be increased with double row planting system.

Specialty coffee is sold in a very expensive price. Specialty coffee is usually consumed as a single origin (without mixed with other coffee). For this reason, the detection of impurities (authentication) in specialty coffee is a very important process to be performed. In this study, UV-visible spectroscopy combined with PLS-DA method were used to discriminate between two specialty coffees from South Sulawesi (Kalosi and Toraja). A number of 100 ground roasted coffee samples were used for Kalosi and Toraja, respectively (1 gram each sample). A standard aqueous extraction procedure of the coffee samples using distilled water was performed and the spectral data of aqueous samples of Kalosi and Toraja coffee were acquired in transmittance mode using a UV-Visible spectrometer (Genesys™ 10S UV-Vis, Thermo Scientific, USA). The result showed that using PLS-DA method, all prediction samples were correctly classified into their corresponding classes with 100% rate for sensitivity, specificity, and accuracy, respectively.

Aflatoxin M1 (AFM1) is a carcinogenic compound found in milk-based products including infant and young children formula. The aim of this study was to determine the risk characterization of infants and young children to AFM1 through the consumption of formula products. For this purpose, the Estimated Daily Intake (EDI) for infants and young children was calculated by multiplying AFM1 concentration in 44 infant formulas, 53 advanced infant formulas, and 16 growing up formulas with consumption data. The concentration of AFM1 in these formula products were retrieved from food registration in Indonesian FDA from January 2015-June 2018. The average concentration of AFM1 in infant formula, advanced infant formulas, and growing up formula (lower bound-upper bound) were 0.0226-0.0335; 0.0418-0.0510; and 0.0038-0.0123 ng/g, respectively. The average EDI of AFM1 for infants and young children aged 0-6 months, 6-12 months, and 1-3 years based on individual consumption were 0.260-0.386, 0.282-0.343, 0.029-0.092 ng/kg body weight (BW)/day. The average EDI of AFM1 for infants and young children aged 0-6 months, 6-12 months, and 1-3 years based on the recommended consumption by food producer (lower bound-upper bound) were 0.403-0.598; 0.663-0.809; 0.031-0.098 ng/kgBW/day. The average hazard index (HI) values for infants aged 0-6 months and 6-12 months (lower bound-upper bound) were greater than 1 (one), i.e., 1.94-2.88 and 3.20-3.90, which indicates there is a health risk. However hazard index value for young children aged 1-3 years (lower bound-upper bound) were less than 1 (one), i.e., 0.15-0.47, which indicates a lower health risk. Keywords: advanced infant formula, aflatoxin M1, growing up formula, hazard index, infant formula

Farmworkers in the coffee production section at CV. Frinsa Agrolestari are dominated by women, namely 9 women and 5 men. While the coffee production process is fairly heavy, female farmworkers continue to become workers in this company. The large number of females as farm workers can be caused by the low income in her family. Inadequate income from her husband salary will encourage some of the wifes to get additional income. This research was motivated by this phenomenon. The purpose of this study was to determine the level of welfare of female farmworker families, the contribution of female farmworkers income to the family income, and the motivation of female farmworkers working in the production field at the coffee factory of CV. Frinsa Agrolestari, Margamulya Village, Pangalengan, Bandung Regency. The approach taken in this research was a qualitative approach, using a case study with interviews based on indicators of family welfare levels according to the regulation of BKKBN in the year of 2005. The results of the study showed that the family welfare level of a female working in the field of coffee production at CV. Frinsa Agrolestari was in the Prosperous Family category I indicating that the income can fulfill basic needs such as clothing, shelter, health, and education. Contribution of income of female farmworkers to the family income ranged from 22.2% (the lowest) to 50% (the highest). Motivation of the female farmworkers to work is 89% due to economic reasons and 11% due to social reasons. Keywords: family, farm, labor, welfare,women

Forest harvesting of natural-forest production in Indonesia is carried out with a high felling intensity, thus has changed the forest biomass. Several studies have shown a strong correlation between harvesting intensity and the reduction of wood volume in the forest. This condition may disrupt the stability of forest ecosystem. This study aimed to calculate and classificate logging residue of low-harvest intensity (one tree plots-1) in Indonesian Forest Concession. The study was conducted in private concessions in North Kalimantan and West Papua. Measurements were made in 30 dynamic circular sample plots with a radius of 2 times the height of the felled tree. The average size in North Kalimantan was 2.5 ha plot-1 and in West Papua was 1.5 ha plot-1. The sample plots were randomly placed in the cutting compartment. All logging residues with dbh ≥10 cm were measured after felling. The logging residue is classified into felled and unfelled trees and four types of logging residue (fallen tree, broken stem, stump, branches and twigs). The low felling intensity produced logging residue ranging from 4.98-5.55 m3 ha-1. The result indicated that logging residue came from felled trees (66%) was higher than those from unfelled trees (34%). The most common type of logging residue of felled tree was branches and twigs, broken stem and stump. The logging residue came from unfelled tree dominated by fallen tree followed by broken stem, branches, and twigs. Keywords: felling intensity, forest conservation, natural forest, selective cutting

Etawah grade goat is a result of grading up line between Kacang and Etawah goats, which well adapted to Indonesia’s humid tropical climate. This goat is a dual-purpose goat breed for milk and meat production. The objectives of this study were to evaluate the polymorphism of fecundity genes through the investigation of four candidate genes for prolificacy, i.e., BMP15 (exon 1), BMPR1B (exon 1), KISS1 (exon 1), and KISS1 (intron 1) and their associations with the litter size of Etawah-Grade does. The diversity of BMP15 (exon 1), BMPR1B (exon 1), KISS1 (exon 1), and KISS1 (introns 1) genes were analyzed by the PCR-RFLP technique. A total of 106 of DNA samples were collected from Etawah-Grade does at BPTU-HPT Pelaihari in Pelaihari, South Kalimantan (51 heads) and Cordero Farm in Bogor, West Java (55 heads). Genetic polymorphisms between the two Etawah-Grade groups were calculated as well as their allele and genotype frequencies and the Polymorphic Informative Content (PIC). The Kruskal-Wallis one-factor ranked analysis of variance was used to determine whether there was any effect of genotype of the fecundity genes on litter size. The polymorphic information content (PIC) estimated at BPTU-HPT Pelaihari was 0.313, whereas at Cordero farm was 0.174, and overall PIC was 0.244. There was no association between genotypes of BMP15 (exon 1), BMPR1B (exon 1), KISS1 (exon 1), and KISS1 (intron 1) genes and litter size. Results indicated that BMP15 (exon 1) and KISS1 (exon 1) genes were monomorphic. However, the other two loci showed polymorphisms. The BMPR1B (exon 1) locus had two genotypes with the frequency for CC (96.23%) and for GG (3.77%), and KISS1 (intron 1) locus had three genotypes with the frequency for TT (80.19%), AT (17.92%), and AA (1.89%).

Revenue is an important thing for farmers, because with the income the farmers can meet the needs of the household. The higher the income then the welfare of farmers will be improved. The purpose of this research is to identify the characteristics of farmers, analyze farmers' income and factors affecting the income level of rubber farmers in Sako Suban Village. The selection of villages was done purposively but the selection of respondents was conducted by accidental sampling. The data used in the primary data were collected by using interview method. Quantitative data processing used linear regression by using a significant level of 10%. The results of the research showed that the education of the farmers was low, the average age of the farmers was 46 years, and the majority of the farmers work as rubber farmers. Rubber contributed 63% to the total revenue and the rest comes from company laborers and loggers and average farmer incomes was IDR733.389/month. Variables that affect farmers' income are rubber prices, farmers groups, and farmers experience in rubber gardening. The variables that have no significant effect on farmers' income are the education of farmers, the labor in the family, and the land area.
