Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Postharvest technology is needed so that the abundant citrus fruits at harvest time can be utilized and at the same time can increase the added value of these oranges. The potential to increase the added value of Indonesian citrus products is still huge. The processing of oranges into fruit juice drinks can be one way to increase the added value of oranges. Orange juice is currently a trendy drink as it contains vitamin C, which increases the human body's immunity in the pandemic era. The study aims to determine the effects of several types of stabilizers addition with several formulations on the physical and chemical characteristics, as well as sensory properties of the panellists' preference for Keprok Terigas juice. This study made use of Completely Randomized Design (CRD) with two factors, the first factor was the type of stabilizer (CMC, xanthan gum, arabic gum) and the second factor was the concentration of the stabilizer (0.025%, 0.05%, 0.075%, 0.1%). Results of the study indicated that vitamin C contained in the citrus fruit juice ranged from 13.49 to 24.69 mg/100 grams. Citrus fruit juice had a total dissolved solid value of 11.10 -12.63, pH was 3.535-3.787, total acid was 4.567-7.433 and viscosity value of 4.167-43.500 cp. The treatment of several types of stabilizers affected the value of vitamin C content, viscosity, and total dissolved solids, yet it gave no affect on the pH of the citrus juice.

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The composition, structure and type of vegetation are determined by land management patterns and their closely related with the organic matter input, which in turn will determine soil physico-chemical characteristics, in particular soil bulk density, organic-C, and N mineralization. This study aims to measure and compare the soil physico-chemical characteristics and nett N-mineralization, and also nitrogen leaching on agroforestri systems with different levels of tree diversity. The research was conducted on 2 (two) types of agroforestry systems with different compositions; namely simple agroforestry and complex agroforestry. The research was conducted in the Sumber Brantas sub-watershed which is located at 1150 17’00” to 118019’00” East Longitude and 7055’30” to70 57’30” South Latitude, on 3 (three) different plots for each type of agroforestry. The results showed that complex agroforestry systems had a greater input of organic matter (6.55 Mg ha-1) than simple agroforestry (4.68 Mg ha-1), with soil mineral N content of 108.2 kgha-1 and respectively. 120.2 kg ha-1 for complex agroforestry and simple agroforestry. The leached nitrate in the agroforestry systems was also greater (3.16%) than the simple agroforestry systems(1.83%) which was managed with a greater porosity in the complex agroforestry systems indicated by the lower value of soil bulk density (0.84 gcm- 3) compare with simple agroforestry (1.09 gcm-3).

Fitria W, Bambang AN, Hidayat JW.  2020.  Local People’s Perception of jambu village, kledung district, temanggung regency to the long-tailed macaque disturbance. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang  20 Oktober 2020. pp. xx.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).In recent years, the disturbance of long-tailed macaques (Macaca fascicularis) in cultivated plants has become a threat to communities near forest because it caused in significant economic losses. The interaction between humans and wildlife often creates different perceptions that determine the success of treatment efforts. The purpose of this study is to determine the general description of long-tailed macaque disturbance and public perception in responding to it so that effective treatment strategies can be formulated. The research method used is descriptive quantitative and qualitative where data collection is done through a survey with a questionnaire and interviews with respondents. The research result shows that almost all the people of Jambu Village have suffered losses due to long-tailed macaque disturbance that has occurred in the last 5-10 years with more than 20 individuals. Macaque that often attack fields consist of all age groups from puppies to adult individuals. Most people do not know the status and benefits of long-tailed macaque ecologically, biomedically, and economically, but they understand the causes of macaque's infesting fields and settlements, namely the need for food sources. Despite being a threat to the economy and safety, most people can accept the existence of long-tailed macaques if they live in the forest. From the research results, it can be concluded that the majority of the Jambu Village community has a negative perception of long-tailed macaques but has tolerance for their presence in the forest so that conservation-based management strategies can be implemented with community participation.

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang  20 Oktober 2020. pp. xx.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Water is one of the main needs of living things. Everyday human life needs water, starting from drinking water, water recreation, aquaculture, animal husbandry and agriculture. About ¾ of the human body is made up of water. Water is very important, so humans must maintain the availability of water. Water availability needs to be balanced with the maintenance of water quality, so that it can be seen that the water is in good condition or polluted. Clean water needs attention according to SDGs number 6 concerning the availability of clean water and sanitation. The quality of water in water bodies such as rivers, lakes, swamps, reservoirs and others needs to be monitored so that water can be used properly according to its purpose. This study aims to examine the method of calculating the water quality index which is commonly used in determining water status so that the characteristics of the water quality method can be identified and the advantages and disadvantages of this method. The method used is literature study from related journals. The water quality index (IKA) method used in Indonesia includes the IP, Storet and NSF WQI methods. The results of the study will describe the advantages and disadvantages as well as the characteristics of the appropriate method used in accordance with the research needs which are expected to facilitate the selection of water quality monitoring methods.

Abstract

Silalahi RE, Munandar M, Achadi T, Gustiar F, Malahayati N. 2020. Growth and organoleptic test of green mustard biofortification results of calcium cultivated hydroponic. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The low calcium intake of the Indonesian people is one of the causes of the high risk of osteoporosis. Therefore, support is needed to meet the body's calcium needs. This study aims to determine the growth and organoleptic test of mustard greens (Brassica juncea L.) as a result of biofortification with calcium (Ca) cultivated hydroponically by floating rafts. This study used a descriptive test with 2 treatments and 4 replications, consisting of 0 ppm (P0) control treatment and 300 ppm calcium (P1) treatment of mustard plants. The parameters observed included plant height, number of leaves, level of greenness, plant fresh weight, plant dry weight, moisture content, root crown ratio, calcium content, food fiber and organoleptic tests with components of assessment of color, taste, preference, and texture. The research treatment did not significantly affect plant growth seen from the height of the mustard greens with calcium treatment, only a slight decrease from the control mustard plant, but it greatly affected plant production as seen from the wet weight and dry weight of the control mustard plant which had a higher weight than the mustard plant with calcium. Giving a calcium concentration of 300 ppm increased the number of leaves, greenness of the leaves, increased calcium content and dietary fiber in mustard greens. The assessment of the organoleptic test results showed that mustard greens with calcium treatment were dark green, had a sweet taste, had a crunchy texture, and were preferred by panelists. So the mustard plants that get the addition of 300 ppm of calcium can be accepted and liked by the community to meet their daily calcium needs.

Hamidson H, Suwandi S, Nurhayati N. 2020.  Epidemiology  of  leaves caused by fungi in corn plants in Indralaya Utara Ogan Ilir district. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang  20 Oktober 2020. pp. xx.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).This study aims to observe the development of disease in maize plants caused by fungi related to the epidemiology of leaves diseases caused by fungi in corn plants in Indralaya Utara District, Ogan Ilir Regency. The low production of maize is caused by the attack of plant-disturbing organisms from both pests and diseases. The survey results showed that two maize diseases were leaf blight and leaf rust. Leaf blight can reduce production by up to 50%. Leaf blight (Helminthosporium sp; Bipolaris sp; Exserohilum sp) and leaf rust disease (Puccinia sp). The highest incidence percentage was found in plants aged 60 DAS at 16.64%. The results of the seed health tests of the six types of corn seeds observed were Annom and Sukanegara seeds growing faster, Annom seeds growing faster on the surface of the seeds followed by Bisma, Lamuru, and Srikandi Kuning seeds. Annom seeds mostly carried seed fungi that grew on the seed surface followed by Bonanza seeds. Types of fungi carried by the seeds, namely Aspergillus sp; Penicellium sp; Trichoderma sp; Diplodia sp; and Bipolaris sp.
