Abstract

ABSTRACTThe objective of this research was to study the differences effects of interstock on scion growth, flowering and fruiting of ‘Nambangan’ pummelo (Citrus grandis (L.) Osbeck). The research was conducted from January to December 2005 in a green house of Cikabayan Research Station IPB, Dramaga. Th e research was arranged in randomized completely block design with singe factor i. e. kind of intertock consisted of Flying Dragon, Troyer, Citrumelo, and Rangpur Lime. All interstocks were grafted on Javanche Citroen rootstock. The result showed that the growth, flowering and fruiting of ‘Nambangan’ pummelo was significantly affected by kind of interstock. Citrumelo interstock tended to induce more vegetatif with low generatif growth of ‘Nambangan’ scion. Troyer, Rangpur Lime and Flying Dragon resulted in moderate growth of ‘Nambangan’ scion, however only Flying Dragon induced ‘Nambangan’ scion to produce more flower and fruit as compared with other interstocks. There was no significant different in carbohydrate content in leaves and C/N ratio among scion with four interstock studied.Key words: interstock, Nambangan, pummel o, flowering

Abstract

ABSTRACTPummelo productivity is still low, therefore efforts should be made to increase its flowering and production. The objective of study was to determine the effectiveness of strangulation combined with the application of breaking dormancy substances to improve flowering of pummelo. The experiment was conducted in January to November 2015, at the Cikabayan Experimental Research Station, IPB. The carbohydrate and nitrogen analysis was done in laboratory of Postharvest Agriculture Research Institute, Bogor. Three-year-old pummelo grown in field was subjected for this research. Experiment used a completely randomized design (CRD) with two factors. The first factor was treatment to stimulate flowering, consisted of 3 levels i.e. single strangulation, double strangulation and control, and the second factor was the use of dormancy breaking substances, consisted of 3 types i.e. KNO3, Ethepon and BAP. Strangulation was performed by pressing the wire with a diameter of 2.0 mm into stem as deep as the diameter of the wire. Strangulation was done simultaneously and then released after 3 months. Dormancy breaking substance was applied immediately after releasing the wire for strangulation with the concentration of 200 ppm KNO3, 100 ppm Ethepon or 100 ppm BA. Treatments were replicated 4 times. The results showed that single and double strangulation treatments for 3 months were an effective way to induce flowering of young pummelo trees. Double strangulation produced more flowers as compared to single strangulation.Increased carbohydrate content and C/N ratio in leaves were observed on flower induced trees. Strangulation treatment for 3 months can increase flowering of young pummelo trees. Application of dormancy breaking substances did not have any effect on flowering induction in pummelo.Keywords: carbohydrate content, dormancy breaking substance, flower induction, pummelo, strangulationABSTRAKProduktivitas pamelo masih rendah sehingga perlu upaya peningkatan pembungaan dan produksinya. Penelitian ini bertujuan untuk mengetahui efektivitas strangulasi yang dikombinasikan dengan aplikasi zat pemecah dormansi dalam meningkatkan pembungaan jeruk pamelo. Penelitian dilaksanakan pada bulan Januari sampai Nopember 2015, bertempat di Kebun Percobaan IPB Cikabayan. Analisis karbohidrat dan nitrogen dilakukan di laboratorium BB Pasca Panen, Bogor. Percobaan menggunakan tanaman jeruk pamelo “Nambangan’ berumur 3 tahun dengan Rancangan Acak Lengkap (RAL) dua faktor. Sebagai faktor pertama yaitu perlakuan untuk menstimulasi pembungaan, terdiri atas 3 taraf perlakuan yaitu perlakuan strangulasi tunggal, strangulasi ganda dan kontrol, dan sebagai faktor kedua adalah penggunaan zat pemecah dormansi terdiri atas 3 jenis yaitu KNO3, Ethepon dan BAP. Masing-masing perlakuan diulang 4 kali sehingga terdapat 36 unit percobaan. Strangulasi dilaksanakan dengan melilitkan kawat dengan diameter 2.0 mm pada batang dengan menekan kawat ke batang sedalam diameter kawat tersebut. Strangulasi dilakukan serentak pada batang, strangulasi dilepas setelah 3 bulan kemudian. Zat pemecah dormansi diaplikasikan segera setelah pelepasan kawat strangulasi dengan konsentrasi masing-masing 200 ppm untuk KNO3, 100 ppm untuk Ethepon atau 100 ppm untuk BAP. Hasil penelitian menunjukkan perlakuan strangulasi selama 3 bulan merupakan cara efektif menginduksi pembungaan tanaman jeruk pamelo. Perlakuan strangulasi ganda menghasilkan bunga lebih banyak dibandingkan dengan strangulasi tunggal. Tanaman yang telah terinduksi menunjukkan tingginya kandungan karbohidrat pada tajuk tanaman sehingga meningkatkan rasio C/N. Perlakuan zat pemecah dormansi tidak memberikan pengaruh yang nyata terhadap pembungaan jeruk pamelo.Kata kunci: kandungan karbohidrat, pamelo, pembungaan, strangulasi, zat pemecah dormansi

Abstract

The demand for fruits in Indonesia continues to increase along with the increase in public consumption. Melon is one of the fruits that requires intensive handling in its cultivation because it is vulnerable to environmental changes and diseases. This study aims to determine the effectiveness of adding KCL and KNO3 fertilizers on the growth and yield of two melon varieties. This study used a non-factor randomized complete block design (RCBD). There were four treatments consisting of a combination of fertilizers and melon varieties, namely P1 (KCL and new madesta varieties), P2 (KNO3 and new madesta varieties), P3 (KNO3 and glamour varieties), P4 (KCL, KNO3 and new madesta varieties), with 6 replications so that there were 24 experimental units. The results showed that P3 treatment gave the best results in stem diameter, number of leaves, early flowering age, fruit weight and fruit diameter. P2 treatment gave the highest average yield on the parameters of fruit flesh thickness and total soluble solids (PTT). P3 treatment has the potential for further research, P3 treatment can fulfill the expected criteria with the highest fruit weight of most treatments. The provision of alternative K sources did not give a real response to melon plants, thus it would be more efficient to use K sources that are more economical in the melon cultivation system carried out.

Abstract

The high demand for water spinach demands increased production through more efficient cultivation techniques. One important factor that affects plant growth and production is lighting. This study aims to optimize the growth and production of two varieties of water spinach by adding LED lights with a certain light spectrum and duration. The study used a Nested Complete Randomized Block Design (RBD) consisting of two factors. The first factor is the light spectrum (L) with 3 levels, namely the red light spectrum of the 18/6 photoperiod (L1), the blue light spectrum of the 18/6 photoperiod (L2), and the red-blue light spectrum of the 18/6 photoperiod (L3). The second factor is the variety of water spinach (V) consisting of two levels, namely the curly water spinach variety (V1) and the lacinato water spinach variety (V2). Each treatment was repeated 4 times so that there were 24 experimental units. Data analysis used ANOVA with a 5% confidence level and further testing using the Duncan test. The results showed that the growth and production of the two varieties of water spinach were more optimal with the addition of the red-blue light spectrum.

Abstract

Red chili (Capsicum annuum L.) is crucial for household consumption and the food industry, but its productivity declines due to soil fertility depletion caused by excessive chemical fertilizer use. This study aims to evaluate the effects of combining biological fertilizer and NPK on the growth and yield of red chili plants. A factorial completely randomized design (CRD) experiment with 12 treatment combinations was conducted at the UG Technopark Greenhouse, Cianjur, West Java, from May to August 2023. The first factor was the frequency of biological fertilizer application (none, biweekly, weekly, and twice a week), while the second factor was the NPK fertilizer dosage (none, 50%, and 100% of the recommended dose). The results showed that both fertilizers significantly influenced plant growth and yield, with the optimal treatment being the application of biological fertilizer twice a week combined with 100% of the recommended NPK dosage. A significant interaction between NPK dosage and biological fertilizer frequency was observed, affecting plant performance. These findings highlight the importance of integrating biological fertilizers with NPK to enhance red chili productivity while reducing reliance on chemical inputs, contributing to more sustainable agricultural practices.

Abstract

Penambangan data merupakan proses penemuan pengetahuan dalam basis data yang melibatkan identifikasi, validasi, kebaruan, dan pemahaman terhadap pola data yang besar dan kompleks. Salah satu bidang yang dapat menerapkan analisis berbasis data mining adalah pertanian. Jаmur mеrupаkаn ѕаlаh ѕаtu komodіtаѕ pеrtаnіаn yаng mеmіlіkі nutrіѕі tіnggі dan nіlаі еkonomі yаng mеnjаnjіkаn dаlаm аgrіbіѕnіѕ. Klasifikasi jamur menjadi penting untuk menentukan apakah jamur aman dikonsumsi atau beracun. Penelitian ini bertujuan untuk mengevaluasi akurasi klasifikasi berbagai algoritma dalam dataset jamur, yang diperoleh dari UC Irvine Machine Learning Repository. Beberapa algoritma yang diuji meliputi k-Nearest Neighbor (kNN), Naive Bayes, Support Vector Machine (SVM), Decision Tree, Logistic Regression, Linear Discriminant Analysis, Artificial Neural Network (ANN), Convolutional Neural Network (CNN), Extra Trees Classifier, AdaBoost, dan Voting Feature Intervals 5 (VFI 5). Berdasarkan hasil penelitian, akurasi Hold Out dari algoritma tersebut berkisar antara 0,8763 hingga 1,0000, sedangkan akurasi Cross Validation berkisar antara 0,8396 hingga 1,0000. Algoritma Decision Tree (Tuning Model), AdaBoost, dan ANN menunjukkan akurasi tertinggi (100%) pada kedua metode pengujian. Namun, penggunaan Cross Validation lebih disarankan untuk menghindari risiko overfitting, meskipun memerlukan waktu pemrosesan yang lebih lama dibandingkan dengan Hold Out. Algoritma seperti k-NN, Decision Tree, ANN, AdaBoost, dan CNN berpotensi mengalami overfitting, terutama jika dataset tidak cukup kompleks atau kelas data tidak seimbang.
