Abstract

Malang Regency is an area that has many historical relics. One of the relics whose existence is preserved and can be visited is the temple landscape of the heritage of the Singosari kingdom which has the character and identity of the characteristics of the heritage of the Singosari kingdom. The Singosari Kingdom has several temples including Singosari Temple, Kidal Temple, Jago Temple, and Sumberawan Temple which are Hindu Buddhist temples based on the function, shape, and reliefs that exist in these temples. The purpose of this study is to analyze the potential of the temple landscape from the Singosari kingdom in the hope that it can be developed as a historical tourist attraction in Malang Regency, there are actions to preserve the temple landscape, and improve the economy of the local community around the temple. The research method used is descriptive quantitative. Based on the results of the analysis of existing path aspects, historical aspects, objects and attractions aspects, and visual aspects of the landscape in the landscape of the Singosari Temple, Kidal Temple, Jago Temple, and Sumberawan Temple, it shows that the four temples have the potential to be developed as historical tourism relics of the Singosari Kingdom in Malang Regency.

Abstract

ABSTRAKPenurunan hasil tomat disebabkan oleh kendala iklim, hama dan penyakit. Hama yang umum menyerang tanaman tomat adalah ulat grayak (Spodoptera litura). Hama ulat grayak mampu menurunkan hasil hingga 85% dan bahkan kegagalan panen. Mengingat berbagai dampak negatif pestisida kimia, perlu dilakukan penggunaan pestisida nabati. Pestisida nabati merupakan pestisida yang berasal dari tumbuhan yang mengandung senyawa metabolit sekunder seperti alkaloid, terpenoid, fenolik. Senyawa tersebut berfungsi sebagai penolak, penarik, antifertilitas (pemandul) dan pembunuh. Keuntungan penggunaan pestisida nabati adalah mudah terurai sehingga tidak mencemari lingkungan, relatif aman bagi manusia dan hewan. Penelitian ini bertujuan mengetahui efektivitas ekstrak daun mimba dan daun sirsak terhadap larva ulat grayak instar 2. Penelitian dilaksanakan menggunakan Rancangan Acak Lengkap (RAL) pada bulan Desember 2022-Januari 2023 di Laboratorium Hama dan Penyakit Fakultas Pertanian, Universitas Tribhuwana Tunggadewi Malang. Parameter yang diamati meliputi larva berhenti makan, mortalitas, kecepatan kematian, dan intensitas serangan pada daun. Data dianalisa menggunakan Anova dan diuji lanjut dengan uji BNJ 5%. Hasil penelitian menunjukkan bahwa perlakuan ekstrak pestisida nabati berpengaruh terhadap persentase larva ulat grayak berhenti makan, mortalitas, kecepatan kematian, dan intensitas serangan. Ekstrak daun mimba 80 ml sama efektifnya dengan ekstrak daun sirsak 80%. Pada 8 JSA ekstrak daun mimba dan ekstrak daun sirsak mampu menekan larva berhenti makan berturut-turut sebesar 17.50% dan 15%; pada 48 JSA mengakibatkan mortalitas larva ulat grayak sebesar 42.5% dan 40.00%; pada 48  JSA mengakibatkan kecepatan kematian sebesar 7.80 ekor/jam dan 7.35 ekor/jam; pada 72 JSA mengakibatkan kerusakan pada daun tomat sebesar 20.00% dan 22.50%. ABSTRACTThe decline in tomato yields is caused by climate constraints, pests and diseases. The common pest that attacks tomato plants is the armyworm (Spodoptera litura). Armyworm pests can reduce yields by up to 85% and even crop failure. Considering the various negative impacts of chemical pesticides, it is necessary to use plant-based pesticides. Botanical pesticides are pesticides derived from plants that contain secondary metabolite compounds such as alkaloids, terpenoids, phenolics. This compound functions as a repellent, attractant, antifertility (sterile) and killer. The advantage of using vegetable pesticides is that they are easily decomposed so they do not pollute the environment, and are relatively safe for humans and animals. This research aims to determine the effectiveness of neem and soursop leaf extracts against second instar armyworm larvae. The research was carried out using a Completely Randomized Design (CRD) in December 2022-January 2023 at the Pest and Disease Laboratory, Faculty of Agriculture, Tribhuwana Tunggadewi University, Malang. Parameters observed included larvae stopping eating, mortality, speed of death, and intensity of attacks on leaves. Data were analyzed using Anova and tested further with the 5% BNJ test. The results of the study showed that treatment with vegetable pesticide extracts affected the percentage of armyworm larvae that stopped eating, mortality, speed of death, and intensity of attacks. 80 ml neem leaf extract is as effective as 80% soursop leaf extract. At 8 JSA neem leaf extract and soursop leaf extract were able to suppress larvae from stopping eating by 17.50% and 15% respectively; at 48 JSA resulted in armyworm larval mortality of 42.5% and 40.00%; at 48 JSA resulted in a death rate of 7.80 individuals/hour and 7.35 individuals/hour; at 72 JSA resulted in damage to tomato leaves of 20.00% and 22.50%.

Abstract

This study aimed to identify and know the associated insects and their role in sweet corn plants. This study used a non-factorial randomized block design (RBD) with three kinds of treatment; yellow traps, net traps, and ground traps. Each treatment was repeated nine times so that there were 27 experimental units. In each treatment plot, the sample size is 3m x 1m. Sampling of insects on corn plants using net traps, yellow traps, and soil traps. The result showed that found 1,012 insects, from 8 Ordo and 25 families in sweet corn plants. In the vegetative phase found 636 insects in various roles. 408 insects are pests and 228 insects that are natural enemies. A total of 406 insects were found in the generative phase, 196 of which were pests and 210 were natural enemies.

Abstract

Polyploidy induction is a plant breeding strategy to improve agronomic traits. This study aimed to examine the effect of colchicine concentration and immersion duration on the morphological, phenological, and production characteristics of cayenne pepper (Capsicum frutescens L.). The experiment used a Factorial Randomized Block Design with two factors: colchicine concentration (0, 10, 20, 30 ppm) and immersion duration (12, 24 hours), replicated four times. Data were analyzed using two-way ANOVA and the least Significant Difference (LSD) test at ?=5%. The results showed a significant interaction between both factors on plant height, leaf area, flowering time, fruit length, and flesh thickness. The 30 ppm colchicine with 24-hour immersion (K3W2) produced the widest leaves (7.98 cm) but delayed flowering initiation to 80 days after planting (DAP). The highest yield (7.2 tons/ha) was achieved at K3W2, showing a 92% increase compared to the control. Indicated polyploidy resulted in shorter fruits (4.32 cm) but with larger diameter (1.35 cm), thicker flesh (0.044 cm), and fewer seeds (53.75 seeds/fruit). It is concluded that 30 ppm colchicine effectively induces polyploid phenotypic changes in cayenne pepper, increasing yield but reducing generative fertility.

Abstract

Penelitian ini bertujuan untuk mengukur kadar timbal (Pb) dan tembaga (Cu) pada buah jeruk manis (Citrus sinensis) yang diambil dari dua lokasi sentra produksi di Kabupaten Malang, yakni Desa Tegalweru dan Kecamatan Poncokusumo. Pengambilan sampel buah dilakukan secara acak dari tiga titik berbeda di masing-masing lokasi. Kandungan logam berat dianalisis menggunakan metode Spektrofotometri Serapan Atom (SSA/AAS) di Laboratorium Balai Besar Industri Agro, Bogor. Hasil pengukuran menunjukkan bahwa seluruh sampel dari kedua lokasi memiliki kadar Pb di bawah batas deteksi alat (<0,035 mg/kg). Sementara itu, kadar Cu yang terdeteksi berkisar antara 0,48 mg/kg (Tegalweru) hingga 1,93 mg/kg (Poncokusumo). Seluruh nilai tersebut masih jauh di bawah ambang batas maksimum yang ditetapkan oleh SNI 7387:2009, yaitu 0,5 mg/kg untuk Pb dan 5,0 mg/kg untuk Cu. Dengan demikian, dapat disimpulkan bahwa buah jeruk dari kedua sentra produksi tersebut aman dikonsumsi dari aspek cemaran logam berat Pb dan Cu. Meskipun demikian, diperlukan pemantauan lingkungan pertanian secara berkala untuk mencegah potensi akumulasi logam berat di masa depan, terutama di wilayah dengan aktivitas budidaya intensif seperti Poncokusumo
