Abstract

Chili (Capsicum annuum L.) is one of the horticultural commodities that have high economic value which is used as vegetables or cooking spices, industrial raw materials, and has export opportunities. The development of superior chili varieties requires a large variety of germplasm that can be used as parents to be crossed with each other to obtain new superior traits. One of the efforts to determine the diversity of plants is to characterize the morphology and production. The purpose of this study was to obtain distinguishing characters among ten genotypes of large chilies, to determine the value of genetic parameter estimators for several genotypes of large chilies and to identify important characters that influence the yield of large chili genotypes. The study was a single factor field experiment in the form of 10 large chili genotypes arranged in a Randomized Completely Block Design (RCBD) with 3 blocks as replication. Genotypes of large chili are: Pilar, Arimbi, Baja, Panex, Forever, Columbus, Gada, Dewa, Rengku, Beautiful. Observation variables are plant height, stem diameter, number of leaves, width of leaves,  leng of leaves, flowering age, harvest age,  fruit length,   fruit weight per plant, fruit diameter, and weight of fruit.. Chili characters that show high genetic diversity are leaf width, while high phenotypic diversity is in fruit weight parameters. High heritability values were found in the characters of flowering age, harvest age, and fruit diameter.

Abstract

Problems related to the sustainability of water resources often occur, both from the impact of the erratic change of seasons, the reduction in water catchment areas, to the many cases of water pollution in Indonesia. However, the main problem of all that lies in the community itself where awareness of the importance of conservation and management of water resources is still low. The selected study was located in Sengi Village, Dukun District, Magelang Regency, Central Java Province. The local community utilizes springs as the main water supply source, but the water management carried out by the community is still classified as less than optimal. Therefore, there is a need for conservation efforts so that the sustainability and function of these springs can be maintained properly. The results of the study showed that spring conservation was carried out by constructing a spring reservoir with a volume of 2 m3 for spring 1 and a spring reservoir with a volume of 5 m3 for spring 2. In addition, a social approach to the community in the local area regarding the preservation of the condition of the springs was also carried out. affixed area

Abstract

Antibacterial bath soap is one of the liquid cleansing preparations made from basic ingredients and is used to clean the skin with the main benefit of effectively killing bacteria and other types of microorganisms so as to minimize skin irritation. Durian fruit skin contains alkaloids, flavonoids, steroids, triterpenoids, and tannins as antibacterial compounds and saponins that can produce foam in water. The main objective of this research is to formulate antibacterial bath soap from durian fruit peel extract. This type of research is an experiment, carried out by Soxhlet extraction of durian skin using 20%, 40%, 60%, 80%, and 96% methanol as solvent. The antibacterial bath soap formula was made at a concentration of 25% durian skin extract including formulas F, G, H, I, and J using a differentiating ingredient, namely the durian skin extract, and was tested for physical and chemical evaluations including organoleptic, homogeneity, pH, foam height, and irritation test. For the results of the remaining durian skin extract, organoleptic tests will be carried out which include  texture, color, and the presence or absence of fungi on the storage time of durian skin extract. The results showed that antibacterial bath soap from durian peel extract had met the requirements for a stable physical-chemical evaluation test which included pH, foam height, and irritation test as well as organoleptic and homogeneity tests for formula F.

Abstract

Anthocyanins are chemical compounds contained in a plants. Anthocyanin pigments are water soluble and have pink, red, purple, blue, and yellow colors. Anthocyanins act as a natural food coloring in the form of dry powder or concentrated liquid. The production of anthocyanins from butterfly pea as a natural dye is currently not maximized yet. The anthocyanin extraction process in this study was carried out by heating the butterfly pea using aquadest as a solvent. The purpose of this study is to find the optimum conditions for extracting anthocyanins from butterfly pea, to learn the effect of temperature and pH on the absorbance and color values of the butterfly pea extract with distilled water, as well as its application as a natural dye in food. In this study, it was found out that the optimum concentration was obtained at a ratio of 15 grams:500 ml (weight of butterfly pea:solvent volume) at pH 4. This proves that the concentration will increase along with the increase in the absorbance value. The optimum concentration value occurs at a temperature of 60°C. While the lowest transmittance value was obtained in the sample with a ratio of 15 grams: 500 ml (weight of telang flower: volume of solvent) at pH 4 and a temperature of 60°C. This proves that the transmittance value is inversely proportional to the concentration value. The butterfly pea extract that obtained at pH 4 produced a bluish purple color, pH 5 produced a purplish blue color, pH 6 produced a light blue color, pH 7 produces a blue color, pH 8 produces a bluish green color, and pH 9 produces a green color.

Abstract

Water is one of the important factors in fulfilling human needs. The existence of water on earth is very abundant but the quality doesn't meet the standards. The system value of a DWTP can be seen from 3 aspects, quality, quantity, and continuity of water produced. Dry season, increasing population, and the age of DWTP are things that will be faced in maintaining the three aspects of value. Seeing the several conditions experienced by PDAM Tirta Wijaya, it is necessary to conduct an evaluation to determine the performance of each unit, the quality of raw and production water, the fulfillment of water needs, the operation during the dry season and the optimization that needs to be done.  The method used is direct observation to DWTP Kesugihan. The results of the evaluation of DWTP Kesugihan are that the flocculation, sedimentation and filtration units is not comply with SNI 2774-2008, the water demand in 2029 is 1170.7 L/second.  From this study it can be concluded that the performance of the DWTP unit is categorized as quite good, the quality of raw water is still worthy of consideration, the quality of production water has met the quality standards, DWTP Kesugihan has not been able to fulfill water needs in 2029 as much as 80% coverage, there is no operational standard during the dry season. Optimization of DWTP Kesugihan by increasing the height of the filtration unit to 6.5 m, the nozzle diameter to 0.05 m and the number of nozzles to 500 and making SOPs for the dry season
