The research used a plot design divided into 3 replications, with the main plot consisting of 9 clones of second ratoon sugar cane, namely clones SB11, SB03, SB01, SB12, SB04, SB19, SB20, BC01, and clone BC02 and the subplot was a test of giving LOF, namely without LOF, LOF A 10 l.ha<sup>-1</sup>, and LOF B 6 l.ha<sup>-1</sup>. The research was carried out at the Sambiroto P3T Test Plantation, Sooko, Mojokerto in March - July 2022. The results showed that clones SB03, SB01, SB04, SB19, SB20, BC01, and BC02 were clones that interacted with the provision of LOF, this was shown in the variable number of cluster plants -1. The SB 01 clone showed the best agronomic characteristics compared to other clones Giving LOF was significant for stem weight and brix values, especially giving LOF B. Agronomic characters with high heritability predicted values were found in stem height and diameter, leaf area, and brix. Agronomic characteristics with moderate heritability estimates are found in the number of leaves and plants in clump<sup>-1</sup>. The agronomic character with a low heritability prediction value is plant stem weight<sup>-1</sup>. There is high hope of genetic progress in all agronomic characters except plant stem weight<sup>-1</sup>. Stem weight and brix showed a positive correlation with sugarcane yield. Agronomic characteristics that have the potential to be used to obtain superior sugarcane varieties are stem height, stem diameter, number and area of leaves, number of clump-1 plants, and brix.</p> 2023-12-27T00:00:00+07:00 Copyright (c) 2023 Gontor AGROTECH Science Journal RISK ANALYSIS OF COFFEE PROCESSING ENVIRONMENT WITH HAZARD IDENTIFICATION AND RISK ASSESMENT (HIRA) METHOD 2023-08-01T12:02:16+07:00 Andrew Setiawan Rusdianto <p>Coffee processing produces waste consisting of liquid waste in the form of coffee washing water and solid waste, namely coffee skins. Coffee waste has the potential to pollute the water and soil environment. Bumdesma Raisa is a jointly owned enterprise of Ijen Sumber Wringin, Bondowoso district, East Java province. This study aims to identify risks that are directly related to community activities, determine the level of risk at each risk and how to control it to overcome the problem of coffee waste. Risk assessment will be carried out using qualitative analysis, namely using a risk matrix, where the level of risk is obtained by multiplying the probability of the occurrence of a hazard and the consequences of the risk matched with a matrix table. The matrix will show the level of risk so that control methods can be determined based on the literature and conditions at the location and using the FGD (Focus Group Discussion) method. There are four categories of low risk and two categories of moderate risk. Control that can be done is the processing of coffee skin waste into compost, cattle supplements and briquettes. As for the control of coffee washing water waste, namely by making a simple wastewater treatment plant and making liquid fertilizer.</p> <p>&nbsp;</p> 2023-12-07T00:00:00+07:00 Copyright (c) 2023 Biodiversity and Species Composition of Butterflies in the Coban Glotak Waterfall, Malang, Indonesia 2023-10-30T10:25:46+07:00 Wakhid Wakhid I Made Indra Agastya Astri Sumiati Reynald Umbu Renggi Nggani <p>Butterflies have an essential role in helping pollinate flowering plants so that the process of natural plant propagation can take place. In addition, the existence of butterflies is important because of their role in the ecosystem as bio-indicators of environmental damage. This study aims to analyze the diversity and species composition of butterflies in the Coban Glotak area, Malang, Indonesia. A sampling of butterflies was carried out in July 2023 - August 2023 in three waterfalls, agricultural and bush habitats. Sampling was carried out using an observation transect with a length of one thousand meters (1000 m). The butterfly survey was carried out in the morning between 09.00-12.00 a.m. when there was no rain. The abundance of butterflies found was analyzed using the Shannon-Wiener Index for the Diversity Index, while species similarity was analyzed using the Bray-Curtis Index. There were 32 species of butterflies found in this study belonging to five families, namely Nymphalidae, Pieridae, Lycaenidae, Papilionidae, and Hesperiidae with a total of 102 individuals recorded. The Nymphalidae family had the highest percentage of abundance (68.63%) and the lowest was the Hesperiidae family (1.96%). <em>Ypthima baldus, Udara akasa</em>, and <em>Neptis vikasa</em> ranked 1st, 2nd, and 3rd with relative abundances of 30.39%, 9.80%, and 5.88%, respectively. Based on the ecological index (dominance, diversity, evenness, and species richness) it shows that the waterfall habitat has the highest index value compared to the other two habitats. The species similarity between waterfall habitat and agricultural habitat is only 19%, while the species similarity between waterfall habitat and bush habitat is only 13%. Agricultural habitats and shrubs have a species similarity value of 36%.</p> 2023-12-11T00:00:00+07:00 Copyright (c) 2023 The Combination of Planting Media and Fungicide Immersion on the Growth of Moon Orchid (Phalaenopsis sp.) Acclimatization Stage 2023-08-10T06:15:27+07:00 Ach. Habibullah Netty Ermawati <p>Acclimatization is a critical stage in the propagation of tissue culture plants, because at this stage the plant must be able to develop and form strong tissue so that it can adapt to the new environment. The aim of this research was to determine the interaction of a combination of planting media and fungicide soaking on the growth of moon orchids (Phalaenopsis sp.) at the acclimatization stage. The method used was a factorial Completely Randomized Design (CRD) and was repeated three times. The first factor is a combination of planting media consisting of 100% white moss, 50% white moss + 50% fern, 50% white moss + 50% wood charcoal, and 50% white moss + 25% fern + 25% wood charcoal. The second factor is the length of soaking in fungicide, namely without soaking, soaking 6 minutes and 10 minutes. The data obtained were analyzed using ANOVA and continued with the 5% DMRT test. The results of the research showed that the combination of planting media treatment of 50% white moss + 25% fern + 25% wood charcoal not significant on all observed parameters. These results show that the planting medium has a very important role in the growth of orchid plants, sterilization of explants at the acclimatization stage only needs to be done if the source of contaminants is in the planting material.</p> 2023-11-22T00:00:00+07:00 Copyright (c) 2023 The Potential of Dryland as An Area of Agro-Tourism and Kalimantan’s Local Fruit Producing for Buffer New National Capital Region 2023-08-01T11:30:17+07:00 I Gede Kariasa Zein Andri Faisal Akmal Andini Putri Syawalluna Riza Adrianoor Saputra Noor Laili Aziza Muhammad Noor <p>Dry land in Kalimantan has a potential area of 41.61 million ha or 29% of the area in Indonesia of around 144.47 million ha which can be developed for agriculture, plantations, and forestry. Dry land has the potential to be developed for annual crops such as fruit forest plants. Welcoming Kalimantan as the National Capital City (IKN), the development of agro-tourism and local fruit production in Kalimantan as a buffer zone for food security has national and international strategic and political values. Agro-tourism is prepared based on conservation and environmental preservation, especially local Kalimantan fruit. The steps needed to develop local Kalimantan fruit agro-tourism are determining land, making ponds, determining types of local fruit commodities, land and landscape arrangement, land preparation, selecting superior seeds, plant care, empowering local human resources, building facilities and infrastructure, promotion and partnerships, as well as the grand opening. There are several divisions of land in the Kalimantan local fruit agro-tourism area, on the mainland, namely local fruit preservation land, forest areas located on the outermost part of agro-tourism, determining the location of ponds as water sources, camping areas for visitors who want to stay overnight, as well as culinary areas. The dry land used will be planted with horticultural commodities for the first five years to fill the land until the local fruit produces fruit. Furthermore, local fruit preservation will be determined to realize Kalimantan local fruit agro-tourism. The existence of local fruit agro-tourism in Kalimantan will become a new icon for national agro-tourism, education, and environmental preservation for the archipelago. Government and community support regarding the development of local Kalimantan fruit agro-tourism is urgently needed.</p> 2023-10-30T00:00:00+07:00 Copyright (c) 2023 The Manure Dosage and Relay Cropping with Chili (Capsicum annum L.) on the Growth and Yield of Peanuts (Arachis hypogaea L.) 2023-07-24T09:49:40+07:00 Djoko Setyo Martono Wuryantoro Wuryantoro Nazil Abdi Muqorobin <p>Peanut (<em>Arachis hypogaea L</em>.) in Indonesia is an important agricultural commodity after soybean, which has a strategic role in the national food system as a source of protein and vegetable oil. Chili (<em>Capsicum annum</em> L.) is a horticultural commodity with good prospects. The community widely uses it as a cooking spice, an ingredient in traditional medicine, and a mixture in the food industry. The insertion of chili plants into peanut plantations will increase the effectiveness and efficiency of nutrient utilization from the given manure and have a positive economic impact. This study aimed to determine the effect of doses of goat manure and the insertion of chilies on the growth and yield of peanut plants in the intercropping system of intercropping plants. The study used a randomized block design (RBD) with two factors. The dosage of manure with three levels D1 = 2.5 kg goat manure, D2 = 5.0 kg goat manure, and D3 = 7.5 kg goat manure as the first factor, and the insertion of chili plants at the following levels: S0 = monoculture and S1 = relay cropping with chili as the second factor. The results showed an interaction between the treatments of various doses of goat manure (D) and the addition of plant inserts (S) on plant height aged 56 days after planting, fresh weight, dry weight, and peanut weight. The treatment of various doses of goat manure was not significantly different in all parameters except plant height 42 days after planting. Treatments of chili as relay cropping were not significantly different on all parameters except the weight of 100 peanut seeds. The higher dose of manure causes a decrease in the production of peanuts, which are inserted into the chili plants, but the amount of goat manure can increase the leaf area of the staple peanut plant but has no impact on the total growth/plant dry weight.</p> 2023-10-30T00:00:00+07:00 Copyright (c) 2023 The Influence of Seedling Age And Dosage of Phosphate Fertilizer on Rice Harvest Result (Oryza sativa L.) 2023-03-16T13:50:17+07:00 zainol arifin Ida Sugeng Suyani Susilo Ribut Anggarbeni <div><span lang="IN">This research aims to determine the effect of seed age and phosphate fertilizer dosage on rice yields.

At the beginning of corn growth, plants are still susceptible to plant pests and disease organisms (OPT) on the soil surface. Therefore, pitfall can be used to monitor the insects. Research consisted of two treatments, the location of pitfall traps on the edge and middle of the cornfield. The research area measures 11 x 14 m with 24 pitfalls for each treatment. The pitfall trap was installed using a 220 mL plastic glass buried deep and filled with a detergent solution at a dose of 23 grams in 25 liters of water and left for 24 hours. All insects obtained and identified at the family level and their numbers populations. Data were analyzed using the T-Test. There are seven families whose role as pests are Acrididae, Gryllidae, Carabidae, Agromyzidae, Termitidae, Cicadellidae, and Blattidae. There are four families as natural enemies, namely Libellulidae, Lycosidae, Araneidae, and Formicidae. The percentage of pests and natural enemies on the edge of the field is 33.57% and 66.43%. In addition, the pest percentage in the middle of the cornfield is 28.69%, while natural enemies are 71.31%.</p> <p> </p> 2023-10-30T00:00:00+07:00 Copyright (c) 2023 Gontor AGROTECH Science Journal The Effect of Different Types Manure and Altitude on Wheat Production 2023-04-06T23:27:54+07:00 Siti Nurul Iftitah Nurul Baroroh Ayyu Rahmawati Vatjarjinanto Vatjarjinanto Ringguh Puji Utami <div> <pre><span lang="EN-US">The aim of this research is to know the effect of different manure types on the yield of wheat (Triticum aestivum L.) dewata 162 at different altitudes.
