Pertumbuhan tomat pada lingkungan berbeda memberikan perbedaan hasil karena adanya interaksi genetik x lingkungan yang mempengaruhi ekspresi suatu gen pada kondisi lingkungan tertentu. Penelitian ini bertujuan untuk menduga nilai ragam genetik serta nilai heritabilitas arti luas pada genotip tomat tipe determinate di dua lingkungan tanam. Penelitian dilakukan dari Maret hingga Juli 2021 dengan menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) di dua lingkungan tanam (Depok dan Jakarta). Perlakuan terdiri dari 3 genotip tomat generasi F6 dan 2 varietas komersil diulang sebanyak 3 kali. Hasil penelitian menunjukkan bahwa lingkungan tanam memberikan pengaruh terhadap pertumbuhan dan perkembangan genotip tomat yang digunakan. Nilai ragam genetik pada setiap karakter tergolong dalam kriteria sempit, kecuali pada karakter tebal daging buah dan luas daun. Nilai heritabilitas arti luas terhadap karakter yang diamati menunjukkan kriteria tinggi, kecuali pada karakter diameter buah (kriteria sedang) dan karakter tinggi tanaman (kriteria rendah). Genotip RwTa-4-10U-6U-4U-2U memberikan penampilan terbaik pada kedua lokasi tanam, dengan tinggi tanaman lebih rendah (91,09 cm), diameter batang lebih kekar (9,69 mm), buah lebih panjang (5,64 cm), diameter buah lebih besar (4,25 cm), total padatan terlarut lebih tinggi (5,22ºBrix), bobot per buah lebih besar (48,43 g), serta umur berbunga lebih genjah (25 HST) dibandingkan varietas Tantyna dan varietas Tora.ABSTRACTTomatoes growth in different environments give different results due to genetic x environment interaction that affect the expression of genes in a certain environmental condition. This study aimed to estimate the genetic variance and the broad sense heritability of determinate tomato genotypes in two growing environments. The study was conducted from March to July 2021, using a Randomized Complete Block Design (RCBD) in two planting environments (Depok and Jakarta). The treatments consisted of 3 genotypes of tomato generation F6 and 2 commercial varieties with 3 replications. The results showed that the environment affected the growth and development of the tomato genotypes used. The genetic variance was classified into narrow criteria except for flesh thickness and leaves area. The heritability value showed high value except for fruit diameter (medium) and plant height (low). The genotype RwTa-4-10U-6U-4U-2U gave the best performance at both planting locations, with lower plant height (91.09 cm), more harder stem diameter (9.69 mm), longer fruit (5.64 cm), larger fruit diameter (4.25 cm), higher total dissolved solids (5.22ºBrix), greater weight per fruit (48.43 g), and early flowering (25 DAP) compared to the Tantyna and Tora varieties.

Kentang (Solanum tuberosum) merupakan salah satu bahan makanan yang penting di dunia. 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.

Used plastic in the form of polybags in the rehabilitation of plantation and agricultural land takes a very long time to be degraded naturally by sunlight (photodegradation) and soil microorganisms (biodegradation). 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.

The performance of tappers has an effect on the high or low level of production and productivity of the latex produced by a company. However, many tappers are only fixated on the production target (quantity) that must be achieved rather than paying attention to the quality of the tapping. This study aims to analyze the performance of tappers based on the quality of tapping and the factors that influence it and to determine the application of the premium system. The research was conducted from November to December 2019 at PT Perkebunan Nusantara VII Way Berulu, Pesawaran, Lampung. The research used a survey method and purposive sampling technique by selecting 12 tappers based on age, education level, and work experience and observing 5 sample trees from each tapper. Data were analyzed using descriptive analysis and level test analysis of 5%. The results showed that the performance of tappers is in the good category, because it has few wood wounds and the depth of tapping and bark consumption is in accordance with recommended norms. The factors of age, education level and work experience do not have a significant effect on the performance of tappers. All tappers do not receive a premium because it does not exceed the task bases.
挺杆的性能影响公司生产的乳胶的高或低生产水平和生产率。然而，许多挺杆只关注必须实现的生产目标（数量），而不是关注攻丝的质量。本研究旨在根据攻丝质量和影响攻丝质量的因素分析挺杆的性能，并确定高级系统的应用。这项研究于2019年11月至12月在楠榜省Pesawaran的PT Perkebunan Nusantara VII Way Berulu进行。该研究采用了调查方法和有目的的抽样技术，根据年龄、教育水平和工作经验选择了12名采穗工人，并从每个采穗工人身上观察了5棵样本树。数据分析采用描述性分析和5%的水平检验分析。结果表明，由于其木材损伤较少，且攻丝深度和树皮消耗量符合推荐规范，因此其性能属于良好类别。年龄、教育水平和工作经验等因素对挺杆的性能没有显著影响。所有挺杆都不会获得额外奖励，因为它不会超过任务基数。

Cocoa is one of the commodities as a foreign exchange earner in addition to oil and gas. However, Indonesian cocoa imports have increased from year to year due to low cocoa productivity. Whereas in terms of region, Indonesia has the potential to become a new cocoa power country in the world of cocoa production. This study examines the effect of rainfall, the number of rainy days, and air temperature on cocoa production in the Gunungkidul district. This study uses a quantitative descriptive method. The data used in this study is secondary data in the form of time series data on rainfall, rainy days, air temperature, and cocoa production in 2016-2020 in Gunungkidul Regency. The regression analysis results showed that all observed climatic factors such as rainfall, rainy days, and temperature did not have a significant effect on cocoa production in Gunungkidul Regency. However, the time-series data shows that the highest cocoa production was in October 2017 and November 2018 to January 2019, when rainfall and intensity (rainy days) began to increase. Meanwhile, the air temperature in Gunungkidul Regency for five years is around 24-26°C, which is the optimum temperature for cocoa growth. This study concludes that rainfall, rain intensity (rainy days), and temperature affect fluctuations in cocoa production.
