The study aimed to find the most appropriate chilli planting system to suppress the development of major pests and increase chilli yields. The research was conducted at the IVEGRI. The study was conducted from April to December 2018, and the experimental method using an RBD was repeated four times. Treatments: (A). Chilli and tomato planted together (B). Tomatoes were planted one week after chilli (C). Tomatoes are planted two weeks after chilli (D). Tomatoes are planted three weeks after chilli. (E). The chilli was grown monocrop without silver black mulch (F). Chilli was grown monocrop with silver black mulch. The results: Chilli and tomato intercropping had a good effect on suppressing aphids population 14,65%-48,91%, white flying 18,30%-27,16%, trips 11%-41,44%, and could increase chilli yields 90%-127% compared to monocropped chilli and 10%-31% monocropped chilli with silver black mulch. The implications of the research results on chilli and tomato intercropping systems can inhibit the development of the main pest population of chilli because they act as a barrier and repellant.

Budidaya komoditas ini umumnya berada di dataran tinggi dengan suhu yang rendah. Jumlah lahan pertanian di dataran tinggi semakin kecil disebabkan antara lain karena alih fungsi lahan. Penanaman kentang di dataran yang lebih rendah menjadi kendala karena adanya peningkatan suhu. Penelitian ini dirancang untuk mengetahui pengaruh ketinggian tempat dan perubahan suhu terhadap tanaman kentang pada fase pembentukan umbi. Tanaman kontrol ditanam pada ketinggian 2921 meter diatas permukaan laut (m dpl) dengan suhu siang/malam (190C/120C). Setelah fase pembentukan umbi, sebagian tanaman dipindah ke daerah dengan ketinggian 115 m dpl dengan suhu siang/malam (300C/240C). Perubahan ketinggian tempat dengan suhu yang berbeda mengakibatkan shade avoidance, perubahan akumulasi biomasa pada batang tanaman dan penurunan hasil panen. Hal ini disebabkan karena penurunan hasil fotosintesa, sukrosa, serta kadar klorofil yang disebabkan oleh faktor genetik dan metabolisme enzim. Oleh karena untuk mendukung permintaan komoditas kentang yang semakin meningkat, pemuliaan tanaman kentang tahan terhadap cekaman suhu diperlukan untuk memperluas area penanaman kentang di dataran menengah maupun dataran rendah.ABSTRACTPotato (Solanum tuberosum) is one of the important staple foods in the world. This plant is mostly cultivated in high-altitude regions with low temperatures. As the number of lands for potato cultivation is getting smaller due to land conversion. Potato cultivation in low-altitude regions with high temperatures yields low productivity. This study was designed to determine the effect of altitude and temperature changes on potato plants in the tuber formation phase. Control plants were planted in an area with an altitude of 2921 meters above sea level (m asl), with day/night temperatures (190C/120C). After the tuber formation phase, some plants were transferred to areas with an altitude of 115 m above sea level and day/night temperatures (300C/240C). Change in altitude with different temperatures resulted in shade avoidance, changes in the accumulation of biomass on plant stems, and yield reduction. This is due to decreasing sucrose content as photosynthesis assimilates, and chlorophyll content due to genetic factors and enzyme metabolism. Therefore, to support the increasing demand for potato commodities, breeding potato plants resistant to heat stress is needed to expand the potato planting area in middle or low altitudes. ","PeriodicalId":34207,"journal":{"name":"Jurnal Agro Industri Perkebunan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90154536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One way to overcome this deficiency is to make bio polybags that function as nursery containers. This research aims to make biopolybags from empty fruit bunches (EFB) more environmentally friendly because they are easily decomposed into natural fertilizers for plants. The research was carried out from June to September 2021 at The Processing Technology Laboratory and Material Laboratory, LPP Polytechnic. Bio polybag is made in several stages, i.e. grinding, mixing of materials and adhesives, shaping, drying and mechanical testings. Mechanical tests carried out are compressive tests, tensile strength tests, and hardness tests, and to confirm the results, a density test was performed. Each mechanical property test was repeated three times. The samples represent each variation of the variables. The best bio polybag result is the bio polybag of EFB, which is reinforced by a 6 g rice husk filler with a tapioca adhesive of a measure of 20%. The highest test value obtained is: 1,495 kg.cm-2 for press strength value; 404,46 kgf.cm-2 (39,67 MPa) for tensile strength; and 63,99 HV for hardness value. The existence of this bio polybag is expected to replace the plastic that is difficult to degrade because it can decompose quickly, is more practical to be planted directly, and does not cause root damage during seedling.","PeriodicalId":34207,"journal":{"name":"Jurnal Agro Industri Perkebunan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45745124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
