Abstract
True shallot seeds (Allium cepa var. ascalonicum L.) or True Shallot Seed (TSS) has begun to be used widely as planting material. However, not all types of shallot plants can flower and produce true seeds perfectly because the majority of shallot plants in Indonesia are grown in the lowlands with temperatures of more than 30°C. Although there are some local varieties, which naturally flower, they have not been tested until producing true seeds. This study aims to determine the effect of vernalization and benzyl amino purine (BAP) on the Bauji variety onion plants’ generative growth. The research was conducted from July to November 2020 in Jember Regency at an altitude of 89 asl. The research design using a factorial randomized block design. The first factor is vernalization, while the second factor is BAP concentration at 50, 100, and 150 ppm. The results showed an interaction between vernalization factors and the use of BAP, and single-use of BAP did not significantly affect the generative growth of Bauji variety shallot. The vernalization treatment separately actually gave an increasing effect on the percentage of flowering plants, the number of umbels per planting, the number of flowers per umbel, the number of capsules per umbel, the number of seeds per umbel, the TSS weight per umbel, and the weight per 100 seeds.

Abstract
Black rice is a food that can be consumed as a functional food ingredient. Black rice has not been widely cultivated while the seeds are not commercially available. Besides, black rice also has several weaknesses such as longevity, high plant habitus and low production. This study aims to test black rice accession using gamma ray irradiation in the M1 generation. The research was conducted in January - April 2020 in the experimental rice fields of Cineam District, Tasikmalaya Regency. The materials used are black rice seeds (PH2, PH3, PH5, PH7 and PH8). The treatments tested were 5 black rice accession (PH2M1, PH3M1, PH5M1, PH7M1 and PH8M1) that was irradiated with gamma rays (200 Gray) and 0 Gray as control. The results showed that irradiated and non-irradiated rice growth gave different responses. All black rice accessions after irradiation experienced stem shortening and decreased number of filled grains. Accession PH 7 showed shorter flag leaves, number of productive tillers and fewer total tillers after irradiation. Meanwhile PH8 showed the number of productive tillers and total tillers were more and the panicles were shorter after irradiation.

Abstract
The Kali Bomo watershed has a length of ± 7,417 km and passes through Rogojampi District, Banyuwangi Regency. Rogojampi sub-district consists of 10 villages, including Aliyan Village, Powder Village, Gitik Village, Gladak Village, Karangbendo Village, Kedaleman Village, Lemahbangdewo Village, and Mangir Village. The area of Rogojampi District is 102.25 km2 with a population of 94,268 people. There are 4 watersheds (DAS) in Rogojampi District, namely Binau, Tambong, Bomo and Lumbun which irrigate 11,819 hectares of rice fields and 1,113 hectares of land for corn cultivation. The main problem in watersheds in general is the occurrence of changes in land use due to development both upstream, middle and downstream as well as the conversion of forests into cultivated agricultural land. This has an impact on reduced water absorption function, increased erosion, sedimentation and river water quality. Based on the above conditions, it is very important to conduct water quality analysis, especially in the Kali Bomo watershed so that its sustainability can be maintained. The results of the water quality analysis using the STORET method show that the water quality of the Kali Bomo watershed in the 2017 period from January to April for class I, II, III and IV quality is poor, bad, moderate and moderate, respectively.

Published: April 2021

Abstract
In the present, autonomous environmental supervision and management are still insufficient. The approach of independent parameter controlling emerges to restraining plant growth and resource inefficiency. Developing a new method to control environmental parameters for accelerating plant growth should be deployed to satisfy the optimum condition and resource efficiency. In this paper, we propose a novel advanced crisp logic-based integrated with adaptive hysteresis control and data fusion algorithm to adapt the behaviour of each plant parameter in a certain condition. The objective of the proposed system is to control each plant parameter into the optimum regime while considering the coupling relationship between them. The measurement results show that our proposed system has a more sustained optimum condition and faster change into the desired grade of membership by adapting the hysteresis regime. Based on the measurements, the proposed system produces an optimum condition that are more sustain and stable and produce accelerated plant growth by 35.33%.

Abstract
The extraction of eucalyptus essential oil has been widely carried out with a variety of fairly modern tools and machines, but most of them still use conventional heating methods. The water distillation method for extracting eucalyptus leaves essential oil has been tried using a microwave but is still constrained by the limited penetration of microwaves in the material. To overcome the drawbacks of the extraction method, it is necessary to design a method of extracting eucalyptus leaves essential oil by using ohmic heated hydro distillation with this method, heat will be generated from the material so that it can reduce energy use during the extraction process. This study aims to design and test the performance of ohmic heated hydro distillation for the extraction of eucalyptus leaves essential oil. The method used in this research starts from functional and structural design, component manufacturing, assembly and performance testing of ohmic heated hydro distillation. The design results obtained the dimensions of ohmic heated hydro distillation from the central 304 stainless steel electrode with a length of 50 cm and a diameter of 1 cm. The electrically isolated outermost cylinder functions as a negative electrode with a diameter of 34 cm and a height of 55 cm. The electrodes are connected to a PLN power source with 5 kVA power. The distillation unit is then connected to the condenser of stainless steel 304. The test results obtained a distillation rate of 0.0007 kg per hour with a yield of 0.28%

Abstract
Corn has an essential role in Indonesia, especially as a livestock feed. Corn production has increased significantly over the past five years. Many provinces in Indonesia are a center of corn production, but most do not serve as corn exporter. Gorontalo is one of it that has successfully exported corn. However, corn export from the province is still facing continuity and competitiveness challenges. This study aims to analyze of the corn exports’ potential, opportunities, and challenges from the region. The survey was conducted in 2018. Data and information were collected through in-depth interviews with relevant agencies and respondents are analyzed using SWOT analysis. The results of the study show that Gorontalo Province has a good prospect for exporting corn. The main strength of this province is the availability of two export ports. However, transportation infrastructure to the ports does not optimally support corn export activities. The dynamics of corn trade policies by the Government is also a potential factor to weaken corn competitiveness. Various programs are needed to continuously increase corn exports, including simplifying corn export procedures and licenses, improving infrastructure to facilitate transportation to farmland, and improving export market access by doing good networking with corn importers.
