Abstract

Solid waste has always been a problem for developing countries. In Bandar Lampung, the traditional market is the second largest contributor of solid waste, after households. Data for Traditional Market Solid Waste (TMSW) composition and generation rate in Bandar Lampung is rarely found, even though, data is needed to write the policy for TMSW management and its recycling potential. This research aims to provide data on TMSW composition, generation rate and chararacteristic in Bandar Lampung, also its recycling potential. The sample from 10 of 31 traditional markets in Bandar Lampung is collected for 8 consecutive days in morning and afternoon. Then, the sample was processed to obtain its composition, generation and density. 48.06% of TMSW compositions is donated by vegetable. Meanwhile, metal is rarely found in traditional markets, with only 0.37%. The average density of TMSW is 180.11 kg/m3, while Kangkung Market has the highest density with 237.84 kg/m3 and Cimeng Market has the lowest TMSW density with 123.07 kg/m3. The generation rate of TMSW is 53,602.35 kg/day. Biodegradable wastes from traditional markets in Bandar Lampung, with 53% water contents, can be potentially recycled by composting and/or anaerobic digester because of its economic value and characteristic. Keywords:   Recycling, Solid Waste Management, Traditional Market Solid Waste, Waste Characterization

Abstract

In Lampung cassava stem waste is abundant, its existence is very disturbing, it is only thrown away and burned, it has not been utilized. Its use as an insect repellent is one of the value-added treatment efforts. The purpose of this study was to study the effect of tapioca glue adhesive concentration on the characteristics of mosquito coils at several concentrations of cassava stem powder and nutmeg powder. The treatment, the concentrations of cassava stem powder, nutmeg powder, and tapioca glue adhesive were; a) 16.67%, 26.04%, 58.34%, b) 16%, 24%, 60%, c) 15.38%, 23.07%, 61.53%, d) 14.81 %, 22.23%, 62.9%, and e) 14.28%, 22.32%, 64.28%. This research was conducted to study the physical characteristics (moisture content, density, shatter resistance index, combustion rate, smoke distribution, and organoleptic tests). The method used in this study was a completely randomized design measured using the Indonesian Industrial Standard (SII) No. 1113-84. The results showed that the variety of treatments with the addition of tapioca adhesive in the manufacture of mosquito coils had a very significant effect on moisture content, density, shatter resistance index, and burning time.

Abstract

Nori is a popular seaweed-based food made from red algae Porphyra. The demand for nori in Indonesia is increasing, but Indonesia does not have Porphyra as raw material and lacks knowledge to find alternatives. Pakcoy (Brassica rapa L.) is a nutritious vegetable that is rarely developed and has the potential to become an alternative raw material for nori. This research aims to develop nori made from pakcoy with various binders to approach commercial nori products. This study is expected to produce an alternative nori that is easily sourced and cultivated in Indonesia. The research used a Completely Randomized Design (CRD) method with 10 treatment levels, which are combinations of 3 types of binders (CMC, tapioca, and cornstarch) at 3 concentration levels (3%, 5%, and 7%). Pakcoy nori was made through the processes of washing, steaming, ginding, molding, and drying. The results of the study show that the addition of 3% CMC produces pakcoy nori with the most preferred color, aroma, flavor, and crispiness by the panelists. The use of CMC, tapioca, and cornstarch as binders can produce pakcoy nori with characteristics similar to commercial nori. This research indicates that pakcoy nori has the potential to be developed as an alternative raw material for nori using 3% CMC as a binder. Keywords:  Binder, Brassica rapa L., CMC, Nori, Pakcoy, Porphyra

Abstract

Ginger has a fairly high fiber content that can affect the flour produced when it goes through the powdering process. The purpose of this research was to determine the effect of the direction and the thickness of ginger slices on the level of flour fineness. The experiment was conducted by using a completely randomized design (CRD) with two factors. The first factor is the direction of the slice with two treatments, namely vertical slice (V) and horizontal slice (H). The second factor was the thickness of the slices with three levels, namely 2 mm (T1), 4 mm (T2), and 6 mm (T3). It treatment combination was carried out in triplicates. The parameters observed were moisture content, repose angle, degree of fineness, uniformity index, grain yield, bulk density, and color. The data obtained were analyzed by using Anova test available in Excel and SAS, if there is significant different among the parameters, then is followed by LSD test at α = 0,05. The results showed that the direction of slices significantly affect the fineness of the flour, in which vertically sliced cuts produced better fineness than that of horizontally sliced cuts. The thickness of cuts did not significantly influence the flour characteristic. Keywords:  Fineness, Ginger, Ginger Fiber, Ginger Flour, Slice Direction, Thickness of the Slices.

Abstract

This study aims to determine the effect of aggregate hydroponic growing media and EC (Electrical Conductivity) nutrient solution on the growth and production of melon (Cucumis melo L.). This study used a Factorial Completely Randomized Design (RALF) consisting of 2 factors, namely the type of planting medium (cocopeat and husk charcoal) and the EC value (1, 2, 3, 4, 5) mS/cm, each replicated as much as 3 times to obtain 30 experimental units. The results showed that cocopeat was a planting medium that gave the best response to the parameters of fruit weight and sweetness level with an average fruit weight of 2.46 kg, in addition the use of EC 2 mS/cm and EC 3 mS/cm gave the best response to parameters of fruit weight and sweetness level with an average fruit weight of 2.04 kg and 2.05 kg. Based on these results, the use of EC 2 ms/cm was chosen as the best treatment, because it gives maximum results by spending less resources when compared to EC 3 mS/cm.

Abstract

Gadingrejo District is one of the sub-districts that often experience of flooding. Based on the Central Statistics Agency in 2020, Gadingrejo Sub-district is the only sub-district that floods 7 times in one year. One thing that can be done is the construction or repair of channels/rivers to dispose of floods by taking into account the design fof lood discharge. This study aims to determine the intensity and maximum design flood discharge at the 2, 5, 10, 25, and 50 year return periods in the Way Tebu watershed, Gadingrejo District, determine and the channel capacity of the Way Tebu river, and determine whether the capacity of the Way Tebu river in Gadingrejo District can accommodate design flooding at 2, 5, 10, 25, and 50 year return periods. This research method uses the rational method to determine the design flood discharge and the continuity equation to dbydischarge capacity. The results of the analysis show that theof value of the flow coefficient in 2011 was 0.233 while in 2019 it was 0.257. From these results, it is known that there are land function experts with an increase in the flow coefficient of 0.024. Rain intensity and maximum design flood discharge in the Way Tebu watershed in the 2-year return period is 4,403 mm/hour with a discharge of 39,577 m³/s, the 5-year return period is 5,914 mm/hour with a discharge of 53,164 m³/s, and the 10-year return period is 6,489 mm/hour with a discharge of 58,333 m/s, a 25-year return period of 6.918 mm/hour with a discharge of 62,185 m/s, and a 50-year return period of 7,102 mm/hour with a discharge of 63,837 m³/s. These results are in accordance with the literature which states that the design flood discharge is directly proportional to the intensity of the rain, where if the intensity of the rain that occurs is low, the resulting discharge will be small. Vice versa, if the intensity is high, the resulting discharge will be high. The discharge capacity of the Way Tebu canal/river in Gadingrejo District is 43,146 m³/sec. The capacity of the Way Tebu river can only accommodate design flood discharges during the 2-year return period. However, at the 5 to 50 year return period the capacity of the Way Tebu canal/river can no longer accommodate the design flood discharge. To prevent and reduce the flood discharge, it is necessary to hold river normalization and water conservation programs as often as possible, such as river deepening or sediment cleaning/dredging.

Abstract

The aim of this study is to analyze the potential of sand as a planting medium with the addition of cocopeat, obtain the dose of liquid organic fertilizer for sand media, and find the suitable combination of cocopeat for sand media. The method used is a Complete Randomized Design (CRD) Factorial with 2 factors. The first factor is the combination of planting media (sand and cocopeat) and the second factor is the dose of liquid organic fertilizer. The first factor consists of 3 levels: M1 (sand and cocopeat), M2 (sand and cocopeat mixed), and M3 (cocopeat and sand). Each planting medium has a height of 11 cm. The second factor has 3 levels: P1 (LOF 10 ml/l), P2 (LOF 20 ml/l), and P3 (LOF 30 ml/l). The initial stages carried out in this research include preparing the planting media, seed sowing (for approximately ±16 days), transplanting, and maintenance (watering and fertilization). Observations include monitoring every 3 days (plant height, number of leaves, and leaf width) and final observations (total weight of fresh mustard plants, weight of upper and lower mustard plant parts). The planting media (sand, cocopeat) influenced all parameters. The optimum dose of liquid organic fertilizer is a dose of 30 ml/liter. The most optimal interaction of planting media factors with the dose of liquid organic fertilizer is sand media, cocopeat, and a dose of 30 ml (M1P3) with an average total fresh weight of 4.14 grams. Keywords: Cocopeat, LOF, Planting media, Sand.
