Abstract

Tomatoes are one of the horticultural crops that many people use for consumption in everyday life. Because tThe demand for tomatoes is quite large, but sometimes the availability is too little or too much, it is necessary to study the changing trends or movements in tomato production each year. This research aims to predict tomato plant production in West Nusa Tenggara (NTB) Province, using the Single Exponential Smoothing (SES) method by observing several α values. The best α value is selected by looking at the smallest MAPE (Mean Absolute Percentation Error), MAD (Mean Absolute Deviation) and MES (Mean Square Error).Those value values  is considered to give the best model.The data was taken from BPS from year 2011 to 2022This research aims to predict tomato plant production in West Nusa Tenggara (NTB) Province using the Single Exponential Smoothing (SES) method by observing several α values. The research object taken in this research is data on the number of tomato plant production from 2011 to 2022 in West Nusa Tenggara (NTB) Province. The research object taken in this research is data on the number of tomato plant production from 2011 to 2022 in West Nusa Tenggara (NTB) Province.  Data was analyzed manually using Microsoft Excel. The best α value is selected by looking at the smallest MAPE (Mean Absolute Percentation Error), MAD (Mean Absolute Deviation) and MES (Mean Square Error) values. The research results show that the value α =0,1 is the α value with the smallest MAPE, MAD and MES values. Therefore, for tomato production data from 2011 to 2022 in NTB Province, the best forecasting model using the SES method is given by α =0,1.

Abstract

Porang is a tuber which is abundantly in Indonesia, especially in the East Kalimantan region. However, the potential of porang tubers is still not widely known and optimally developed, particularly in product diversification. The stages in this research consist of making porang’s chips, making porang’s flour, physicochemical analysis of porang’s flour. Based on the research results, the yield of porang chips was 19.12% and porang flour was 23.5%. The color of the flour produced is bright yellow, due to the carotenoid content in porang tubers. The proximate content of flour is dominated by the highest nutritional content in protein content (12.34%), while other proximate contents are as follows water content (12.29%), ash content (7.85%), fat content (1.54%), and carbohydrate content (65.98%) . The high protein and low fat content produced in the research shows the potential for East Kalimantan porang flour to be developed into a functional ingredient which is beneficial for health.

Abstract

One alternative energy that can be used as a substitute for fuel oil and gas is biomass energy such as briquettes. This study aims to determine the amount of heat, moisture content and ash content of briquettes made using hazelnut shells and glutinous rice adhesives that vary in adhesive concentration and particle size. This study used a complete randomised design (CRD) with variations in glutinous rice concentration of 20%, 30%, and 40% while the particle sizes used were 12 mesh and 24 mesh. The results showed that the adhesive concentration did not significantly affect the test parameters while the particle size affected the moisture content, ash content and calorific value of the briquettes. The highest calorific value was obtained by using 24 mesh particle size with 20% adhesive concentration with a calorific value of 5321 cal/g while the 12 mesh particle size produced the highest calorific value of 4704 cal/g at 20% adhesive concentration. The lowest moisture content value was obtained by using 24 mesh particle size with 20% adhesive concentration with a moisture content value of 6.9% while the 12 mesh particle size produced the lowest moisture content value at 20% adhesive concentration with a value of 7.4%. The lowest ash content value was obtained by using 24 mesh particle size with 30% adhesive concentration with an ash content value of 4.99% while the 12 mesh particle size produced an ash content value of 5.82%. The use of 12 mesh particle size is not in accordance with SNI standards because the heating value produced is still below 5000 cal/gr while the use of 24 mesh particle size is in accordance with SNI standards for all test parameters.

Abstract

National soybean production is not enough to meet the national demand for soybeans so there is a need to increase the production of this commodity because it is needed as a raw material for various processed products. The utilisation of dry land as soybean cultivation land is still lacking. This is due to several factors, namely cultivation techniques, and limited fertilisation. So the use of cultivation techniques by applying biocompost fertiliser is one approach to improve soil nutrients and also the use of Trichoderma spp. bacteria helps soybean plants to avoid wilt disease.  This study aims to determine the growth response of several varieties of soybean on dry land by applying biocompost fermented by Trichoderma spp. The method used in this research is an experimental method carried out by manipulating the object of research and the existence of controls. The research was conducted on dry land in Giri Tembesi Village, Gerung Sub-district, West Lombok Regency, the soil type of the experimental site was regusol soil with a pH of 5.7 and organic matter moisture content of 0.77%. The results showed that the application of biocompost to several varieties of soybean has not been able to spur plant growth but in general can adapt to dry land. Differences in soybean varieties resulted in significantly different growth responses in plant height, number of leaves, number of branches, flowering age and weight of 100 soybean seeds. However, there is no significant difference in the application of biocompost on the vegetative and generative growth of soybean in dryland which is thought to be caused by the dose of biocompost given is not optimal. Therefore, further research is needed to obtain the optimal dose of biocompost.

Abstract

Cayenne pepper (Capsicum frutescens L.) is an agricultural commodity with a high economic value. Increasing cayenne pepper production in dry lands is hampered by limited water availability. Therefore, water use efficiency is required, one of which is the implementation of drip irrigation. This study aimed to test the performance of a drip irrigation system in the cayenne pepper farmland of Slengen Village, which is located in the lowlands with a dry climate (D4). Emitter discharge, emitter flow rate, and crop water requirements were used to determine the length of time the drip irrigation system was operational at each growth phase. The results show that the emitter discharge uniformity coefficient was 86.6% with a droplet distribution efficiency of 89.80%, which is included in the good category. This indicates that the drip irrigation system is suitable for irrigating plants evenly within the required water volume.

Abstract

Banyuwangi Regency is one of the largest rice producers in Indonesia. This district at the eastern tip of Java is even nicknamed the national rice barn. Banyuwangi always has a surplus of 300,000 tons of rice every year. This increase in rice consumption will have an impact on high rice bran production. Considering the benefits and potential of rice bran as an industrial raw material, activities can later be developed to process rice bran into industrial raw materials with higher economic value. A processed product derived from rice bran that has the potential to be developed is rice bran oil. This research aims to determine the proximate content of rice bran oil. Through the process of analyzing the characteristics of rice bran oil (moisture content, protein content, fat content, salt content, pH content and ash content) to determine the content of rice bran oil and palm oil as a comparison with proximate tests through a Completely Randomized Design with testing of rice bran oil and palm oil through 3 repetitions in testing. Further testing used the Duncan test with observation parameters in the proximate test. The research results showed that the best results for water content, protein content, fat content, salt content, pH content and ash content were refined rice bran oil compared to palm oil. This is a reference that rice bran oil is still better than palm oil in general. This research will later be able to increase the income of rice farmers. Apart from producing rice, they can also make rice bran oil.

Abstract

Sumbawa cow's milk processing is still limited even though it has the potential to be developed. Therefore, a diversification product like cheese as a source of probiotic is required. Cheese derived from milk that is coagulated using rennet which is expensive and has high halal critical point. Thus, an alternative coagulant that is affordable with low halal critical point such as local plant-based material is needed. This study used Sumbawa local cow’s milk to produce cheese which coagulated using pineapple and gooseberry and the addition of Lactobacillus lactis as the lactic acid bacteria. Observed parameters were clotting time, yield, hardness, protein, total fat, total lactic acid bacteria, and sensory quality. This experiment showed that the cheese yielded using pineapple was higher than that of gooseberry, while the cheese coagulated using gooseberry (26714 N/m2) was having firmer texture. Meanwhile, clotting time, protein content and total fat content of the cheese coagulated using both coagulants were the same. The total lactic acid bacteria of the cheese coagulated using pineapple and gooseberry was similar 10.80 Log CFU/mg and 10.84 Log CFU/mg, respectively. Sensory evaluation using quantitative descriptive analysis showed that the cheese coagulated using pineapple extract has higher aftertaste and bitter taste. Meanwhile, the cheese coagulated using gooseberry extract was dry, grainy, yellowish, and its overall acceptance was higher than that of pineapple.
